The invention relates to a portable system for delivering drugs and can be used, in particular, the patients in the field or outside the sterile from a medical point of view of the environment, where it is possible to adjust the temperature.

Veterinarians often cause for injection domestic animals in pens, sheep farms, under the open sky or in the field. In the treatment of domestic animals, for example, farmers or veterinarians are responsible for periodically giving medicines to a large herd of animals. The duration of these periods could be just a few days. In such circumstances it is necessary to supply drugs had the means to implement vaccinations to a large number of animals in a short time. To work effectively in these conditions, the supply system of medicine should be portable, reliable, convenient and rapid introduction of drug doses to the maximum number of recipients for a minimum time.

U.S. patent N 4128173 describes the package containing intravascular catheter, guide wire, forming guiding means, and an elongated needle. This packaging is designed to use for the location of the intravascular catheter into the abdominal cavity through a small cut in bacteriostatically prepared the skin.

In addition to the fact that these system to the risk of cross-infection between humans and animals. In the usual well-known system uses a disposable pre-filled vials with attached needles. These disposable capsules can be filled with various liquid medicines, including antibiotics, steroids, vitamins or compounds to increase milk yield or the number of meat animals. The important part is bovine somatropin (BST), used as a means of increasing the efficiency of milk yield of dairy animals.

While the use of single vials significantly reduces the problem of cross-contamination, known systems are some problems. First, there is the possibility of frequent breaking of needles from the vials. Also characterized by the frequent breaking of ampoules. These problems occur due to the viscosity of the compositions, which are pre-filled ampoules. In order to overcome the viscosity of the composition, the plunger of the syringe must be reported pressure to enter the structure. The fact that some of the trains you want to freeze in the period between their manufacture and to use, complicates this problem.

U.S. patent N 4968303 describes the syringe for injection pre-filled content nodes from an ampoule of a needle, in General, the th bushing push rod, as well as the push rod slidable mounted in the sleeve.

In U.S. patent N 4865592 described ampoule filled with a drug and having a piston located in the cavity.

Moreover, in some known systems using a single ampoule sometimes breaking the ampoule, there is also the problem of disposal of used vials. Sharp needle attached to each disposable ampoule hazardous to health not only of animals and people during the process of introduction of drugs, but also in General for the population, if used capsules into the waste stream. In addition, some state and Federal regulations require that used drug ampoules were destroyed to prevent reuse. Predominant is the separation of metal needle from the usual plastic disposable vials for two components with different characteristics can be removed separately. Known injection medicines usually do not have tools for easy and safe removal of used needles from disposable ampoule. In addition, in the known systems described case in the form of a case, in the upper plane of which is a receiver for the West end of the syringe together with the needle, and means for separating the needle from the syringe.

In known systems supply drugs often is the destruction of disposable ampoules or they do not have a convenient means to fracture and ejection of used capsules, can not meet the efficiency requirements of the supply of medicines requirements for the system. Therefore, an improved system for delivering drugs.

The basis of the invention is to create a system delivering drugs, which would provide conditions for maximum sterility when performing injections with the destruction of used capsules with a minimum expenditure of time.

The problem is solved in a portable delivery system of medicine because it contains the drug vial, the device of the injection device in the form of a case for separating the needle from the vial.

The invention provides an improved delivery system of medicine that includes two main components. First, the injection device of the type of heater used for maintenance and supply of disposable pre-made am gnetales type and for the Department after the needle from the vial and discard used needles and vials. It also describes improved ampoule and a device for injection.

Device for injection heating type in accordance with the invention includes a cylindrical part, the handle, the hinged gripping lever with spring load and the safety means of the escapement mechanism. A cylindrical part having a cylindrical hole, open on one side and is designed to accommodate disposable vials with attached needle and insert the needle first end in the guide to the end of the cylindrical part. A guiding device serves to hold the disposable ampoule in place and to limit axial movement of the ampoule in the cylindrical part. Within the cylindrical hole of the open side of the cylindrical part is hinged ejector plate with spring load to force the ejection of used capsules of the cylindrical part. The casing is cylindrical part also contains a sliding lock or unlock tool for removing ampules to hold the plate in place at the time of filing of the medication in the vial. Tool unlock to release capsules also has the facility to release capsules, the result is olset in the cylindrical hole of the cylindrical part and is used to supply medication vials, begins to move from the free position, while the drug vial is loaded into an advanced position when one end of the pusher is used to push the plunger down on the drug vial, whereby the medication from an ampoule out through the needle. The other end of the pusher is mounted for sliding on the pressure lever. The plunger also has a small groove to accommodate the reed stopper attached to a safety release device. The tongue of the stopper limits the movement of the pusher down the cylindrical part, with a safety trigger device engages.

The device in the form of a pouch in accordance with the invention includes a plate to protect the feet, is attached to the housing for ejection of used capsules. Plate protection leg consists of at least three plastic sections connected by flexible metal sheets. Plate protection legs covered with waterproof plastic and made in the form of curved shape. The protective plate is designed to protect the user from accidental injection of the legs during use of injection drugs. The curved form of the plates increases the reference is also divided into at least three separate parts, how do you best longitudinal flexibility. On one side of the protective plate are mounted two belt loops and belt for legs that allows you to hang the case on the belt of the user. On the other side of the protective plate is supporting the belt and a clip for holding the device for injection injection type, when it is not used.

To the lower end of the plate to protect the legs to secure the housing is designed to accommodate the cylindrical parts of the device for injection of the injection type. This case holds the tool to separate the needle from the vial and release the needle and ampoule in different containers. The device also includes rotating the receiver to bias the end of the device for injection container for sharp parts is mounted for sliding on the casing, and a container for sharp parts includes a means of pushing the needle, means for holding the bag for used capsules and rocker switch for switching the direction of work a rotating receiver. Rotating the receiver includes means for receiving cylindrical parts of the device for injection of the injection type. The receiver turns vstavit in the receiver and turn in any direction. When the device for injection injection type is rotated at a first angular position in the receiver, the ampoule is placed in the device for injection injection type, pushed to the edge of the blade fixedly mounted on the container for sharp parts that is installed in the casing, resulting in separation of the needle from the vial. Separate the needle after it falls right through the receiver and the cylindrical item in the container for sharp parts, located directly below the receiver and the cylindrical item. When the device is rotated for injection injection type to the second angular position of the wedge element fixedly mounted on said housing, comes in contact with the tool of liberation for the ejection of capsules on the device for injection ninetales type, resulting in the release popped the capsules through the hole in the side of the cylindrical body in the bag for used vials held in the mentioned case. Device for injection injection type, then turns back to its original position and removed from the receiving means. Container for sharp parts is mounted for sliding on one end Zelenina position. In the free state container for sharp parts can be removed from the housing and cover, using a rotary cover with a locking mechanism connected to the container.

The housing also includes a support ridge around the said housing for receiving and holding the bag for used capsules. The housing also contains two curved guide plates connected to him for direction and extending handbags for used capsules. The guide plate also protect the bag from damage from the vials.

The capsules of the invention are improved in order to improve the operation of the device for injection injection type and mechanism of separation of the needle in the device. The comb is connected to the cylinder for ampoules at the end that connects to the needle. This comb is attached to communicate with the recess in the projecting plate of the device for injection, due to which there is rigid fastening of the end of the needle ampoule in place for more effective cutting eject mechanism. In addition, ribs connecting the needle cylinder for ampoules and holding the needle, made with extra forewarned surface intended for Firawn the same two additional enhancements to the device for injection. First, the improvement of devices for injection as a means for regulating the dosage of the medication given by the system. Several longitudinal grooves in the plunger device for injection interact with the tooth in the metering handle, thereby limiting the movement of the plunger in one of four different positions. Dosing the handle can be rotated to select the desired stroke length of the pusher.

The second enhancement ejector plate device for injection is a tool that allows the vial to rotate in one direction but restricts rotation in the other direction. Beveled tooth passing through the hole in the ejector plate, serves to limit the rotation of the filled capsules in one direction while allowing rotation in the opposite direction.

In a preferred embodiment of the proposed invention is easily portable, safe and efficient supply of medicines, including a device for injection injection type tool in the form of a case for the separation and removal of used drug vials and improved drug ampoule. In the following description, the purpose of explanation and not limitation presents concrete is elistan in the art will understand, the invention can be used in other equivalent variants of implementation that do not have these specific characteristics. In other instances, detailed descriptions of well-known aspects of the known systems is omitted in order not to complicate the description with unnecessary detail.

In Fig. 1 shows the preferred implementation of the portable system supply medicines in accordance with the invention, denoted by the main position 1. System 1 supply of drugs, as shown, includes a device for injection injection type, denoted by the General position 2, the case having a plate to protect the feet, the overall position 3, and a housing with a removal device vials, marked mainly by position 4. The device 2 for injection is associated with a protective plate 3 supporting belt 5 with the possibility of removal. Supporting strap 5 is secured in place by a fastener 6. When the fastener 6 is opened, the device 2 for injection can be removed from the protective plate 3. On the other hand the case with removing device 4 is continuously connected with the protective plate 3 at the bottom. On the reverse side of the protective plate 3 attached to it two belt loops to hold the protective plate 3 and housing with udelay. 3) for a solid attachment of the protective plate 3 to the user's foot.

In Fig. 2 and 24 shows a device 2 for injection injection type. The device 2 for injection includes a cylindrical part, indicated in General position 8, connected to the arm 9, to which is attached a protective device 10 for a hand. Similarly, the arm 9 is connected to the articulated arm 11 with spring load. A cylindrical part 8 also includes a cylindrical bore in which is mounted for sliding the plunger 12. A cylindrical part 8 also includes a camera 13 for capsules designed for entering and placing the ampoule in alignment with the hole of the cylindrical part 8. The plunger 12 is connected to a slidable hinge lever 11 in the region of the constriction 14. Region 14 is actually a connection type "a ball in the groove". The groove 15 on the pivot lever 11 allows the ball end of the pusher 12, connected with it, move to the bottom of the groove when the compression of the hinge arm 11. The hinged lever 11 moves the plunger 12 between two positions: a retracted and free. When the movement of the articulated lever 11 (compression) to the handle 9, the plunger 12 includes a through cylindrical hole of the cylindrical part 8 in a vial, R is in the recipient injection. In this case, the hinge arm 11 and the plunger 12 are in retracted position. When removing the pressure on the hinged lever 11, the spring 16 pushes the hinged lever 11 in the free position shown in Fig. 2. The return of the articulated lever 11 in the free position causes a corresponding raising of the plunger 12 from the chamber 13 for ampoules through the opening in the cylindrical part 8. The locking protrusion 17 prevents complete raise the plunger 12 from the hole of the cylindrical part 8. The plunger 12 has a recess 18 for receiving the corresponding trigger latch 19, which is connected to a safety trigger mechanism 20. When the trigger tongue 19 of the safety trigger mechanism 20 is located in the recess 18, as shown in Fig. 2, the plunger 12 may not move in the hole of the cylindrical part 8 and, respectively, the pivot lever 11 cannot move to the arm 9. This safety mechanism prevents accidental release of the contents of the drug vial. When the grip safety trigger mechanism 20 to the handle 9 in the free position of the safety trigger mechanism 20 is rotated around the hinge 21, which causes raise the trigger latch 19 from the notch 22. This action is the establishment of a safety trigger mechanism 20, the spring 23 pushes the safety trigger mechanism 20 back in the free position, it is shown in Fig. 2. When in the free position, the safety trigger mechanism 20 again puts the trigger tongue 19 in the recess 18, which is impossible movement of the pusher 12. In an alternative embodiment of the invention the spring 16 and the spring 23 can be connected in one spring in which one end provides the force required to swivel the lever 11, and the other the force required for the safety trigger mechanism 20. Protective device 10 for a hand is located close to the handle 9 in order to protect the hand of the user when working with the device 2 for injection.

The front end of the pusher 12, the middle to the camera 13 to the sealed ends of the cylinder 24, which is more of a plunger rod 12 and more holes cylindrical part 8, as shown in Fig. 23. The head 24 has a diameter that is slightly smaller than the inner diameter of the ampoule is placed in the chamber 13 for vials. Flat surface of the head 24 (Fig. 26) provides for the release of the stopper 25 of the ampoule head 24. Thus, the cylinder 24 is extended to the position of the stopper 25. The rear end of the pusher 12, attached to the hinge arm 11 connection type "ball in the groove", has a reduced diameter section 14 DL is part of the groove 15. The lower part of the hinge arm 11 is attached in place of the hinge 27 to the arm 9, which can rotate hinge lever 11 around the center of the hinge 27. The back surface of the hinge arm 11 is bent along the shape of the palm. On the front end of the cylindrical part 8 of the guide 28 ampoule is connected to the cylindrical part 8. Guide 28 ampoule has an opening 29 adapted to accommodate the end of the needle drug ampoules with sheath on the needle. The hole 29 forms a cylindrical hole with an inner dimension slightly larger than the size of the end of the needle medicinal capsules. When the ampoule is inserted into the guide 28 capsules and pressed into position in the chamber 13, the end of the needle ampoule at the same time rises to connect with the inner upper surface of the guide 28 for ampoules. This action is intended for proper placement of the needle tip medicinal capsules in the chamber 13. Guide 28 capsules is also designed for proper placement of the vial relative to the slots 30. The needle is ejected from the ampoule through the opening of the slot 30. The device in the case, described below, includes the element in the form of a cutting edge, which is specially adapted and positioned for passing through Etco holding the ampoule and the needle on the seat during ejection.

An important element of the device 2 for injection is eject tool 31. Eject the tool 31 has the means to force the removal of used capsules with pushed the needle from the chamber 13. Eject tool, the overall position 31 includes an ejector plate 32, having a size corresponding to the inner part of the chamber 13. Eject the tool 31 is connected to the cylindrical part 8 of the hinge 33. United thus eject the tool 31 can freely rotate around the center of the hinge 33. This rotation of the ejector means 31 is between the loading position of the ampoule shown in dotted lines, in which one end 34 of the said ejector plate 32 extends from the said chamber so that a new ampoule can be loaded into the chamber 13, and a work position, in which both end of the said ejector plate 32 is placed in the chamber and the vial lying on the ejector plate 32 is coaxial with hole cylindrical part 8. Spring 35, which is located under the ejector means 31, as shown, is used for pushing the pushing means 31 upwards, resulting in the used ampoule with the power removed from the bath ampoule is pushed out from the chamber 13 eject tool 31, eject means 31 is in the loading position and are ready for download a new ampoule. When a new vial is placed in position on the plate ejector means 31 and is directed down into the operating position, the eject plate means 31 is used for the corresponding alignment capsules coaxially with hole cylindrical part 8.

The ampoule is closed in the operating position in alignment with the hole of the cylindrical part 8 of the tool 36 unlock. The tool 36 unlock mounted slidable on a cylindrical part 8 along the pusher 12. The tool 36 unlock is configured to slide in a direction parallel to the movement of the plunger 12 in the hole of the cylindrical part 8. Movement means 36 takes place between two positions: a locking position of the ampoule and release position. In the locking position of the ampoule cutting edge means 36 37 forms a contact with the top surface of the pushing means 31. In addition, the edge 37 forms a contact with the vials loaded in the camera 13, and holds the vial 38 at the bottom in the operating position. Spring 39 compressed between the intermediate wall 40 in the cylindrical part 8 and the circumferential protrusion 41 osvobozhdyeniya district ledge 41. In the locking position of the ampoule means 36 unlock overcomes the force provided by the spring 35 of the lower side of the ejector means 31. Ampoule, located in the chamber 13, the result is held in the working position (i.e., coaxially with the hole of the cylindrical part 8) means 36. The means 36 moves to the position release capsules by means of sliding back in the direction from the camera 13. This action is shown in Fig. 2 by the lines and arrows 42, and part of the means 36 unlock dotted line. The means 36 moves to the position release capsules, the locking end 37 pulls away and stops contact with the ampoule 38 in the chamber 13. After his release capsules from the locking edge 37 of the spring 35 is released and pushes the pushing means 31 in the upward direction, thereby forcing the removal of the capsules from the chamber 13. The front surface of the locking edges 37 are beveled so that the ampoule can push into position without direct manipulation means 36 unlock. The wedge action of the front surface of the locking edge 37 is intended for temporary moving means 36 is in position release capsules, while the ampoule is locked in the reflection, resulting in locking of the ampoule in position in the chamber 13. The plunger 12 passes through the hole formed by a circumferential ledge 39 which help to capture the tool 36 unlock cylindrical part 8.

The supporting means 43 is rigidly attached to the upper side of the cylindrical part 8. The supporting means 43 is intended to form a gap 44 between its surface and the surface means 36 unlock. The slit 44, in particular, adapted for automatic actuation means 36 unlock wedge element attached to the device in the form of a case, as described below. The V-element case is to enter the slot 44 when the device 2 for injection rotates the device in the form of a case, as described below. When the V-element case is inserted into the slot 44, the tool 36 unlock moves back into position release capsules, due to which there is ejection of used capsules from the chamber 13. The supporting means 43 is used to assist clinovia element of the case when the push switch 36 is in position release capsules. The device 36 unlock also has a small rounded end 45 for manual what Finance wedge element or manually using the rounded end 45 necessary force to move the tool 36 in position release capsules, resulting in the ampoule can be pushed from the chamber 13. At termination, the efforts of the tool 36 unlock returns to the locking position of the ampoule through the efforts provided by spring 39.

Except for the items of the spring device 2 for injection injection type, the entire device can be manufactured from plastic. For example, a device 2 for injection can be cast polypropylene or polycarbonate. Technology for casting plastics well known to specialists in this field of technology. General structural and reinforcing elements of the device 2 for injection shown on the drawings. Thus, the described device 2 for injection injection type in accordance with the invention.

In Fig. 1 shows the protective plate 3 and the device 4 in the form of a case for separating the needle from the vial. Plate 3 of the protection of the foot consists of at least three separate plastic sections connected by flexible metal sheets. Plate 3 of the protection of the foot is covered with resistant to changing environmental conditions plastic and is made curved. Protective plate 3 SL is ignota form plate 3 increases the bearing strength of the plate and better match the rounded shape of a foot of a user of the system. Plate 3 for the protection of the foot is divided at least into three separate but connected parts are indicated by the positions 46 and 48, thereby providing improved longitudinal flexibility. On one side of the protective plate 3 are mounted two belt loop that allows you to hang the case 4 on the belt of the user. On the other hand the protective plate has a supporting belt 5 and the latch 6 to hold the device for injection injection type, when not in use. To the protective plate 3 is connected foot belt 49, which is designed for durable attachment of the protective plate 3 to the user's foot.

Case 4 includes a housing 50 that is attached to the protective plate 3 for the legs at the lower end portion 48. The housing 50 includes a flat upper surface 51, in the centre of which is a flow rotating the receiver 52 to the compressor. In Fig. 26 depicts a rotating receiver 52 to the compressor, which basically has a cylindrical shape and in the preferred embodiment, is molded from plastic. The channel, which includes several rectangular sections shaped to accommodate the end of the blower tube passes through the center of Zilina third rectangular surface 55, which includes an inclined inner surface 56, which holds the inclined frame 57, as shown in Fig. 2. The end of the supercharger, containing ampoule, will slide freely in raznoprofilnye channel receiver 52 to until the outer surface of the device 10 to protect the hands does not hook on the flat surface of the case 50 case. This is shown in Fig.3.

Cylindrical receiver 52 is formed near parallel and separated from each other by annular surfaces marked positions 58 - 62. The annular surface 62 is the upper surface in which the channel of rectangular shape, and the surface 58 is the lower surface of the cylinder. These ring the surface like the ribs in design and provide support for receiver 52 without adding a large mass and weight of the case. Rectangular channel comes out of the rectangular hole 63 on the side of the receiver 52. The hole 63 extends from the bottom surface 58 to the upper annular surface 62, with the exception of direct bridge element 64 attached to the underside of the plate 58 across the opening.

The receiver 52 is attached to the housing 50 by the receiver, which is shown in Fig. 26 divided by p is nick 52. The lower annular surface 58 is captured by the annular ridge 67 on the bottom halves 65 and 66 that forms a complete circle when half 65 and 66 are closed together. Likewise annular ledge 68 is combined with the annular channel 69 on the top plate 62 of the receiver 52. Thus, when the housing halves receiver 65 and 66 are closed together and surround the cylinder 52, the cylinder 52 is squeezed between the lower circular ridge 67 and the upper circular protrusion 68 of the receiver's housing formed by the halves 65 and 66. Half 65 and 66 of the receiver's housing adapted for bolting to the bottom surface of the housing 50. The upper surface of the plate 62 of the receiver 52 becomes coplanar.net with the surface 51 of the housing.

Each of the halves 65 and 66 of the casing has a lateral rectangular hole 70 and 71, respectively. The receiver 52 can rotate in the housing of the receiver and the hole 63 can be combined with each of the holes 70 and 71.

The housing 50 also includes a side plate 72 connected to the upper surface of the housing 50. Reference comb 73 extending from the side panel 72 and passing completely around the casing 50 is a means for maintaining the bag 74 for removal of vials used for maintenance and the ciently large to slip on top of the support ridge 73, however, small enough to be put firmly on the supporting ridge 73. The housing 50 also includes a guide plate 75 attached to the plates 72 and passing down from them; the guide plate 75 is intended for the direction of bags 74 to remove the vials over the crest 73 and for the proper unfolding of the bag 74 for removal of the vials. The inner surface of the guide plates 75 also has the advantage that it protects the bag 74 to remove vials from damage to the vials, are pushed out of the receiver 52 of the compressor.

In Fig. 27 and 28 shows a top view in cross section of the receiver 52, collected together with the halves 65 and 66 of the casing of the receiver, the cross-section taken along the plane with the annular surface 61. Round the outer perimeter surface 61 has two cut with an angle of 90oor slots 76 and 77. Slots are located on each side of the rectangular channel in the center of the receiver 52.

The switch 78 of the rotation direction is attached to the halves 65 and 66 of the body around the pivot points 79 and passes through a hole in the side plate 72. The switch 78 of the rotation direction is used to select the direction of rotation of the cylinder 52. The switch 78 SEL the echoes 52 clockwise or counterclockwise. The result of clicking one side of the switch 78 select the direction of rotation of the pin (80 or 81) is in the slot 76 or 77, respectively, which is limited to movement in one of two directions. Due to the fact that the slit is at an angle of 90othe receiver can be rotated 90o.

The lower ends of the halves 65 and 66 of the housing of the receiver provide the support 82 of the slide container for sharp parts when they come together. Bearing 82 slide container for sharp parts, in particular, is designed to accommodate and support the top of the ridge 83 on the upper opposite sides of the container 84 for sharp parts. Thus, the container 84 for sharp parts may slide freely and can be removed from the case 4.

The container 84 for sharp parts intended for keeping many used non-sterile needles, which are separated from the used drug vials. The container 84 for sharp parts shown in detail in Fig. 18 20. As shown, blades 85 (i.e., means for separating needles) attached to the container 84 for sharp parts. The container 84 for sharp parts is made of a material that can prevent the container from being punctured with a sharp needle sharp parts can move in a support 82 slide container for sharp parts and fix in place by a lock 86 container for sharp parts, attached to the support 82 sliding in the holes (Fig.1). Pin 87 that is attached to the switch 88 of the lock container for sharp parts made this to go down into the hole 89 (Fig.9) in the container for sharp parts, resulting in a locking container for sharp parts in the support 82 of the slip. When you want to remove the container 84 for sharp parts, the switch 88 of the lock container for sharp parts move upward, causing the locking pin 87 extends from the hole 90 and releases the container 84 for sharp parts for movement of the support 82 of the slip. The plate spring (not shown) is inserted at the point 91 (Fig. 5) between the container 84 for sharp parts and the end of the sliding bearing. The plate spring pushes the container 84 for sharp parts of the support 82 of the slide when the locking pin 87 extends from the lock 86.

As shown in Fig. 5 and 19 and 20, the container 84 for sharp parts also includes a cover 92 of the container for sharp parts attached to the container by a hinge, which results in the turning of the cover 92 at the top and closing the container 84 for sharp parts. It should be noted that all sharp edges and cutting edge delivery system of medicines in accordance with izaberete the container 84 for sharp parts of the case can be isolated and safely control all dangerous elements of the system.

The separation barrier 93 passes through a portion of the upper cylindrical part of the container for sharp parts, in order to prevent the escape of used needles from the container through the top. The passage 94 passes through the barrier 93 in the cylindrical portion of the container, so that through him you can remove used needles.

In Fig. 3 8 device 4 to remove the vials shown with a device 2 for injection injection type, is inserted in the receiver 52 of the compressor. Action introduction device 2 for injection in case 4 occurs after the device user finishes the injection and flow of the composition in dosage vials installed in the device 2 for injection. Therefore, it is necessary to separate the needle from a used medicinal capsules and remove needle and vials in separate compartments within the case 4. The device 2 for injection and case 4 include the total tool for the implementation of these operations, as described below.

The joint action of the device 2 for injection and case 4 occurs in two main stages. First, the device 2 for injection is inserted into the device 4 in the form of a case, as shown in Fig. 3. Secondly, the device 2 for injection is rotated in one and is trojstva for injection is shown in Fig. 6 and 7. When turning the device for injection of two actions occur in two different positions of angular rotation. In a preferred embodiment, the first angular position corresponds to 45orotation in either direction from the position of placement of the device for injection. Second angular position in the preferred embodiment, corresponds to the 90orotation in either direction from the position of placement of the device for injection. Specialists in the art it is clear that the two actions described below, in each angular position of rotation can occur in angular positions that are not relevant 45oand the 90o.

In a preferred embodiment, during the first turn at 45othe device 2 for injection in either direction, the needle 95 is separated from the used drug ampoules one set of blades 85 attached to the container 84 for sharp parts that is installed in the holder 4. Schematically this is shown in Fig. 30, where the vial 38 and the needle 95, depicted with thick lines shown in the initial position, and the dotted lines show what happens when the compressor and the receiver is rotated at 45o(see also Fig. 4). During Vtorov the effect of interacting components, connected to the case 4. In particular, the wedge element 96 that is attached to the inner surface of each of the halves 65 and 66 of the housing of the receiver, is used to actuate the ejector means of the device for injection, resulting in used and separated USD forcibly expelled from the device 2 for injection through a hole 63 in the receiver 97 and one of the holes 70 and 71 in the casing 65 or 66 of the receiver, respectively, and in the bag 74 for removal of the vials. It should be noted that the container 84 for sharp parts and bag 74 to remove the vials represent two separate containers for different parts of the used capsules. Two pieces of used capsules, thus, can be removed separately.

In Fig. 4 shows a picture of the case 4 from the point on the receiver 52. The circuit device 2 for injection is shown dash-dotted line, when it is inserted into the case 4. Also shows the center of rotation 98 of the device 2 for injection. Because the drug vial 38 installed in the device 2 for injection, slightly offset from the center of the center point 98, the ampoule 38 changes the position of the arc when turning the device 2 for injection, as shown in the drawing. By changing the position of drug is standing apart blades 85, depending on the direction of rotation. At the completion of the rotation of the device 2 for injection at 45othe saw blade 85 will separate the needle from the body of the ampoule. At the time of completion of rotation of the device for injection 90oseparate ampoule is moved into position directly above the blade 85, and separated the needle will fall through the opening between the blades 85 and fall into the container 84 for sharp parts. Thus, rotation of the device 2 for injection provides a separation of needles from drug vials.

In Fig. 5 7 illustrates the operation of the device ejection of capsules and separation of the needle from the vial. In Fig. 5, the device 2 for injection is shown as inserted in the receiver 52 after the filing of a medicinal dose of the composition from the drug vial 38. Also shows the tool 36 release and push the tool 43 support push. Besides, the edge means 36 37 release pushing, holding drug vial 38 in position in the device 2 for injection. Wedge element 96 is also shown in position in line with the gap 44 between the switch 36 release ejection device 43 support push.

When the device is rotated for injection 2 for the first 45orotation of the ampoule 38 and the needle 95 is driven and falls into the container 84 for sharp parts. With continued rotation of the device 2 for injection on the second 45orotate the front end of the wedge element 96 begins to enter the slot 44. Upon further rotation of the device 2 for injection wedge element 96 separates the tool 36 unlock from support means 43. The tool 36 unlock due to this, moves back and away from the ampoule 38. When continuation of such wedge impact edge means 36 37 unlock actually ceases to contact the vial 38. This edge 37 stops to let the pressure down on the vial 38. When removing the pressure downward on the vial 38, the spring 35 on the lower side of the tool 31 release capsules device 2 for injection is free with the power to push the separated ampoule 38 from the chamber 13 of the device 2 for injection. Separate drug vial 38 is then ejected out of the device 2 for injection and falls into the bag 74 for vials. As a result the camera 13 for ampoule device 2 for injection remains in the loading state. When turning the device 2 for injection back into its original position wedge element 96 is removed from the slit 44, and the switch 36 unblock returns to the forward position (locking capsules). In this position, the tool 36 razblokirovat 2 back to the original starting position of the device 2 for injection can be removed from the case 4, and then load the new, pre-filled vials. The cycle of implementation of the injection, feeding and removing of the new capsules can then be repeated.

The case can be made of plastic or metal, suitable for use in harsh environments and under the open sky. Preferably it is made of polycarbonate with a thickness suitable for obtaining an easy case with long life. Plate 3 protect the legs and attached to the case 4 is made with belt loops and foot strap on the back side of the plate 3 to protect the feet in order to ensure the suspension of the case on the belt of the user of the system. Thus, described herein, the delivery system of drugs is lightweight, portable and effective.

The ampoule is improved in the invention to improve the operation of the device for injection injection type and casing of the mechanism of separation of the needle. In Fig. 8 shows the improvement of the ampoule and the corresponding modification of the ejector plate of the device for injection of the injection type. Comb 99 added to the cylinder 100 capsules on the end that connects to the needle 101. Comb 99 formed by preharden is 102, in which the needle 101 is connected to the end of the cylinder 100 means 103 of the support needle. The tool 103 support needle includes longitudinal ribs 104 for placement and retention of the needle 101. Comb 99 adapted to engage the notches 105 to eject the tool 31 of the device for injection, resulting in the locking end of the needle ampoule 100 still in place for more effective cutting blade 85 separating mechanism case. When an improved ampoule is loaded into the device 2 for injection, as shown in Fig. 9, the ridge 99 gears in the recess 105. When the ampoule 100 is in the operating position, as shown in Fig. 10, the ampoule 100 is clamped in place due to the interaction of the ridge 99 and grooves 105 on the needle end of the ampoule. At the other end of the ampoule is clamped in place by means of 36 unlock. Since the ampoule firmly clamped in place in the device for injection, the effect on the separation of the needles carried by the casing 4, more efficiently. This reduced slippage capsules during indentation capsules on the blade 85, as described above. In addition, the clamping capsules using crest as improvements used for more accurate placement and alignment of the ampoule to be cut off at the specified location is second with clamping blower which was inherent in prior devices with an ampoule. In the manufacture of plastic ampoules sometimes there is extra material after the casting process on the circumference of the rear end (i.e. the end opposite the needle end of the ampoule. The remaining excess material can sometimes braking operation, when the device 36 unlock is actuated to eject the capsules from the supercharger. If the rear end of the ampoule is captured by the tool 36 unlock, USD pulled back from the guide 28 capsules, resulting in the separated end of the ampoule out of the camera 13 to the rear end of the ampoule. This can cause jamming of the device 2 for injection injection type. The ridge 49 together with the notch 105 serves to hold the separated end of the ampoule in the chamber 13, which in turn decreases the ability of the clamp blower 2 ampoule.

Another improvement of the ampoule in accordance with the invention is shown in Fig. 11. As shown in Fig. 11, the ribs supporting means 99 needles are made with wedge surface 106 intended for alignment and placement of the separating blade 107 case for more accurate cutting. Wedge surface 106 formed through rozliczeniowa form 108 edge of the blade 107 in the case interacts with the wedge surface 106 of the ampoule to push the ampoule 109 slightly forward, as shown by the arrow 110 in Fig. 13, when the ampoule 109 faces the blade 107 as described above. This is a small movement of the ampoule 109 serves to equalize the ampoule relative to the blade 107 immediately before the separation of the needle shown in Fig. 14.

In Fig. 15-17 shows an alternative example of the improvement of the ampoule in accordance with the invention. In this alternative made improvement capsules and the corresponding change of the separating blade device in the form of case. As shown in the drawings, the ridge 111 is added to the cylinder 112 capsules at the end of the connection needle 113. The ridge 111 can be performed similarly to the ridge 99 described above and shown in Fig. 8 -10. In Fig. 15 wedge surface 111 formed on the blade 114. A method of manufacturing a blade with a shape that is shown in Fig. 15-17, obvious to experts in the given field of technology. This wedge surface of the blade interacts with the ridge 111 for the direction of the ampoule 112 upward, as shown by the arrow 115 when natakamani ampoule 112 on the blade 114 during operation of the Department of needle described above. It is a small move up ampoule 112 serves to properly align the ampoule relative to the blade 114 directly Pereda injection. First, the improvement of devices for injection is a means for regulating the dose entered by the system. The second enhancement ejector plate device for injection is a means allowing rotation of the ampoule in one direction only, resulting in the removal of the needle cap and the proper placement of the beveled needle tip.

In Fig. 21 a further improvement of the device 2 for injection provides a means for regulating the dose, submitted in accordance with the invention. The flange 116 dosing arm 117 captured two notches 118 in each half of the 119 middle or relatednode the end of the cylindrical body 8 of the device for injection, when the cylindrical part 8 is collected. Dosing arm 117 can rotate freely in the cylindrical part 8. Dosing arm 117 is formed with a cylindrical cavity into which you can insert the plunger 120. A number of longitudinal grooves 121 of the plunger 120 interacts with the tooth 122 located in the inner cavity of the metering arm 117. Lateral groove 123 is cut out in a certain place in the plunger 120 so that the tooth 122 is placed in the lateral groove 123, when the plunger 120 on the bottom to rotate 360oaround the plunger 120. Through such rotation of the metering arm 117, the user of the device for injection can choose one of four dosing positions corresponding to the four longitudinal grooves 121 of the plunger 120. In each of the four provisions of the tooth 122 is combined with one of the longitudinal grooves 121, the plunger 120 can freely pass into the casing 8 through the metering arm 117 as long as the tooth 122 will not come into contact with the locking element 124, which is located in the longitudinal groove 121 and perpendicular to the groove. The pusher 120 passes the distance between the side groove 123 and the locking element 124, which corresponds to the number of drugs that are pushed out of the ampoule plunger 120. In each of the four longitudinal grooves 121 of the locking element 124 is located at a different distance from the lateral grooves 123. Thus, the rotation of the metering arm 117, which is located on the cylindrical casing 8, and select one of four different longitudinal grooves 121, the user device for injection can choose one of four different levels of dosage devices for injection.

In an alternative embodiment, the device for injection, marked 125, as shown n the ment of the plunger, in the result, you can use one of the two channels 128 or 129, cut in the plunger. The channels have different lengths, thereby restricting the movement of the pusher in two different positions. These two positions correspond to two different drug doses supplied supercharger.

In Fig. 22 and 23 the improvement of the ejector plate 130 of the device 2 for injection has a ratchet, allowing the vial to rotate in one direction but restricts rotation in the other direction. By limiting rotation in one direction ampoule firmly clamped in the desired position, which might result in the removal of the cap covering the needle. When rotated in the opposite direction of the ampoule can be rotated to align the beveled needle tip.

In Fig. 22 23 and 26 shown eject tool 130. Beveled tooth 131 is shown passing through a hole 133 in the eject tool 130. Spring 132 pushes the tooth 131 up in the hole 133, but allows you to press the tooth 131 down to the point where the top edge of the tooth 131 is flush with the top surface of the pushing means 130. The tooth 131 is eject the tool 130 in the place corresponding to the position cont 130. The longitudinal ribs 134 shown in Fig.8. The tooth 131 beveled to a sharp edge for contact between each of the longitudinal ribs 123 means 103 of the support needle. During the rotation of the ampoule in one direction each edge strikes the beveled surface of the tooth 131, causing the tooth 131 is pushed down in the wedging action of the beveled surface. When each edge is rotated and passes the tooth 131, the spring 132 forces the tooth 131 to return to its extreme upper position between the ribs up until the next edge will not provide downward force beveled surface. Thus, the beveled surface of the tooth 131 allows the rotation of the ampoule. However, rotation in the opposite direction is impossible, since the beveled surface has only one side of the tooth 131. Therefore, the edge, rotating in the opposite direction, can not create pressure on the tooth 131, downward. Therefore, the tooth 131 remains in place, thus failing the opposite rotation of the ampoule.
