The SUBJECT of INVENTION

The invention relates to a syringe and method of its use, and the proposed syringe is a working tool used mainly in the field of health for medical injections and taking blood or other fluids from the body and so on. The invention can also be used in other areas that require the use of syringes for working with liquids in laboratories, different enterprises or in veterinary medicine. The invention also relates to a method of sampling and displacement of fluid with a syringe, which can be used with one hand.

Description of the prior art

Currently used syringes of various types, which, depending on the type of work performed are adapted in accordance with a certain purpose. Different existing syringes depend on the scope and application for which they are used, but working with traditional syringes is well known and is identical in all fields.

Treatment with traditional syringes require a greater or lesser degree of stability, depending on the work in which they should be used, since the use of the syringe for a set of water from a glass and subsequent distribution of it by smaller vessels do not require the same attention and stability, as the perforation in the us for taking blood from a patient.

The main drawback or problem traditional syringes is that require two hands.

The employment of both hands creates a danger, as a sudden movement by the patient may cause damage to the patient or user with a syringe needle.

To prevent the aforementioned risk, there are different syringes or transitional devices to traditional syringes that allow you to use them when working only with one hand.

In U.S. patent No. 3819091 describes an adapter for a conventional syringe, which contains a handle that facilitates the operation of the suction syringe using only one hand. This transitional device solves the problem of stable suction syringe using only one hand, but also increases production costs, as you need to produce a syringe and an adapter. Because an adapter is used only for suction and syringe certain diameter, as soon as the syringe is filled, it must be separated from the coupling and to use as a traditional syringe for injection or removal of fluid.

In U.S. patent No. 3990446 described syringe, which enables the absorption of using only one hand, while removing the liquid must be run with ISOE what Itanium both hands. This syringe longer than traditional syringes, therefore, in order to perform suction, it is necessary to have a stationary support surface for the fingers located at a certain distance, which should move side supports located at the rear end of the piston.

In U.S. patent No. 5135511 describes an adapter for a conventional syringe, which enables the absorption of using only one hand. An adapter consists of two components in addition to the two components that make up a traditional syringe, complicating thus, the Assembly of the entire device. The use of this coupling may cause a larger number of problems during its use due to the large number of component parts.

The syringe described in U.S. patent No. 5582595, unlike the aforementioned syringes, or transitional devices allows you to use one hand to perform both suction and injection. The main problem of this syringe is in its Assembly, which can cause problems when using it. The syringe consists of two main parts: a cylinder provided with two rods in the form of a ledge, passing in the direction of its rear part and having a connecting surface, and a piston with two support surfaces on its end. P is oblama due to the fact, for Assembly of the syringe plunger should be entered in the rear of the cylinder, which means that the surface is available to the rear end of the cylinder, must be able to rotate with respect to one of the rods. This makes the manufacturing process of the product and its Assembly more expensive. It also means that people using this syringe should be treated more carefully and cautiously, because the rotary surface can separate during suction. In this syringe piston similar to the piston in traditional syringes and is the only element that moves relative to the cylinder, the rods remain stationary, as they are attached to the cylinder.

The biggest drawback of the syringe of this type when using it is that it is difficult to control the needle, because the forces necessary for its application, applied at a greater distance from the needle than traditional syringes.

By means of a syringe which is the subject of the present invention, the disadvantages inherent in previous syringes, resolved, as it allows you to perform the suction and ejection of fluid very simply by the natural bend of the toes comfortable, stable and safe power, all the while monitoring the movement and the needle of the syringe. None of the mentioned documents does not allow production is a TB syringe, which can be used by only working with one hand, and which has two independent main parts, which can be easily and quickly assembled as simple as a syringe, as described below.

DESCRIPTION

The present invention relating to the syringe and method of sampling and liquid displacement through this syringe has a special design that allows you to use the syringe, working only with one hand, and provides stable control as two operations: the fence and the displacement fluid can be performed using the same steps of pressing fingers or bending. Traditional syringes during the operation of the suction necessary to use both hands, because if they are used with only one hand, the user of the syringe or the patient may be stuck or hurt.

In order to use the syringe with one hand, traditional syringes were made of different structural modifications, but the ease of use and manufacture have been saved.

The syringe has two main parts, or two elements, one of which is cylindrical and has an inlet and an outlet for liquid at one end, two lateral longitudinal grooves open at the opposite end, and a Central bearing surface, which has a rear part, Il the second bearing surface, and another, the front part, or the third bearing surface, and a Central canal, which is located transversely to the cylinder.

The second part consists of a rod with a piston at one end and two connectors with two protruding elements or pushers on the opposite end. On the side going to the free end (the end that must be entered into the cylinder), the protruding elements or pushers, the end of the two support surfaces (fourth support surfaces)located transversely to the plungers, while at the opposite end of both the protruding element or plunger, connected to another supporting surface of the first bearing surface).

The thickness of the protruding elements may be more or less depending on the diameter of the syringe. In syringes, of which the cylinder has a small diameter, the thickness of the protruding elements at the end, which covers the rod, there will be more to impart greater stability to the moving rod and will also allow you to extend the rear window, which must be inserted finger. These protruding elements in the injection of large diameter will have less or the same thickness as the thickness of the protruding elements.

Syringes may also have the two tabs attached to the ends of the protruding elements and designed to prevent the ingress of foreign the bodies in the grooves, which moves the connecting links.

To use the syringe should be placed the fingers of one hand in a special way, as described below. Syringe, as well as traditional syringes, has two end positions, one for fluid intake and the other for its ejection. When the syringe is in the first position, in which it is ready for absorption, and the piston is near the hole of the cylinder or in contact with him, fingers, namely any toes except the big one, place on the fourth abutment surfaces, and the thumb rests on the second support surface so that it is located in the box, limited between the second support surface and the first bearing surface. As soon as the fingers are placed, you do not need anything more than the execution of the push fingers or bending with, thus creating two opposing forces, the parallel movement of the piston and causing relative movement of the two main parts and, consequently, the absorption liquid.

To eject the liquid inside the cylinder of the syringe, after which the suction is in the second position, the fingers need to change, there is no need to release the syringe from the hands or help yourself with the other hand. To do this, the thumb is placed on the first support surface, and the other two fingers is perutsa on the third support surface. These provisions fingers perform more pressing or bending action, thus creating two opposite forces, the parallel movement of the piston and causing relative movement of the two main parts and, therefore, the extrusion or injection of a fluid.

Thanks to the above construction it is not necessary to rotate the hand, wrist or syringe for use. It is enough to use three fingers of one hand to sequentially change the actions on the fence and pulling the liquid safe and stable manner.

Because the handling of the syringe is simple, it is easy to learn, and it requires no training. Through syringe two functions can be performed quickly and safely, protecting the user from damage caused by poor treatment and suppression of uncontrolled movements.

Movements performed during operations of the intake and expulsion of liquid will always be stable, secure and fully managed, as the direction of the force applied by the thumb in both the action coincides with the axis of the moving rod and piston within the cylinder.

With this design there is no need to release the syringe from the hands, help yourself with the other hand or rotate the hand or syringe to change the position of two fingers when PE is enode from the position of the suction to the position of the ejection liquid or Vice versa.

The security, stability and full control during the suction and ejection is also due to the fact that the pressure of the fingers or bending is the same in both actions, changing only the position of the fingers, which contributes to the ease with which you can control the syringe and study it.

The use of only one arm stable and controlled manner prevents the user from causing accidental needle sticks and cuts with the absorption of fluid with a needle, avoiding, thus, the risk of infection.

When drawing blood or injecting a liquid into the vein the needle provides the advantage consisting in the fact that because it only requires one hand, the fingers of the other hand can hold the vein in one position.

The design of the syringe, which is the subject of the present invention, applicable to syringes used for one or more purposes, and can be used for injecting drugs, blood collection, perform the puncture biopsy, etc.

DESCRIPTION of the PREFERRED OPTION RUN

In the proposed syringe, the method which is the subject of the present invention, the various elements are made different from traditional syringes. This syringe also includes new elements, which allow it to perform two main actions of the syringe, suction or intake and expulsion, with the same force of pressing or bending of the fingers by only one hand of the user at the same time maintaining stability during the use of the Finance syringe and therefore making it use easy and safe.

The syringe has two main parts or an independent basic details, preferably each formed in a single piece and with a special structure. The first main part 10 is cylindrical and has a front end 10A in which is located the inlet and the outlet 11 for the liquid, and a second, open end or neck 10b. On the front end of the syringe 10A, in addition to holes 11, there are tools 16 attaching a needle for subcutaneous injection to the front end 10A.

The second main part 20 contains the first element, or rod 21, which is inserted into the first main part or the cylinder 10 through the mouth of a 10b-mentioned main part 10. The rod 21 at its end, near to the hole 11 of the syringe has a piston 21A, and at the opposite end of the stopper 21b. The second main part 20 can be moved between two positions, namely a first position (Fig.6), in which the piston 21 is in place, close to the front end 10A of the cylinder 10, and a second position (Fig.7), in which the piston 21A is in a location remote from the front end 10A of the cylinder 10. Thus, to get the liquid through the opening 11, the second main part 20 is moved from the first position to the second position, and to remove the through hole 11 of the liquid contained in the syringe, the second main part 20 is moved from the second position to the first is ulozhenie.

Syringe for his work has four main supporting surface, distributed between its two main parts 10, 20.

The second part 20 is divided into two elements, the rod 21 already described and located at one end of the main part 20, and the second element or plunger 22. The plunger 22 has two protruding element 24, 25 connected to the rear part 22b of the first support surface 23a, to which is applied the pressure in the first axial direction to move the second main portion 20 from the second position to the first position.

The cylinder 10 at its neck 10b has a supporting element or Central bearing surface 12, protruding in a transverse direction with respect to the cylinder and forming an integral part of the cylinder 10. This supporting element 12 forms a second bearing surface 12A formed in the rear side of the support element 12, and a third bearing surface 23b formed in the front area of the support element 12. This third reference element 23b pressure is applied in the axial direction D opposite to the first axial direction, to move the second main portion 20 from the second position to the first position.

The plunger 22 of the second main portion 20 has a front end 22A two fourth support surface 27A, 27b formed by two lateral protrusions 24A, 25A, each of colorinterpolator at the free end of one of the protruding elements 24, 25, which can put pressure in the second axial direction, opposite the first axial direction, to move the second main part 20 from the first position to the second position.

The thickness of the elements 24, 25 can be more or less depending on the diameter of the syringe. In syringes, of which the cylinder 10 has a small diameter, the thickness of the elements 24, 25 at the front end 22A, which covers the rod, there will be more, to give more stability to the moving part 21, and also allow you to expand the window 26 to enter the finger. These elements 24, 25 in syringes large diameter at its front end 22A may have less or the same thickness as the thickness of themselves protruding elements.

Syringes may also have the two tabs 30, 31 are attached to the ends of the elements 24, 25 and designed to prevent the ingress of foreign bodies into the grooves 13, 14 which move the connecting links 28, 29.

To enable the application of force in the same direction, which moves the piston during the suction syringe to the second main part 20 has a window 26, the value of which is large enough for insertion into the window of the thumb of the user when the second main part 20 in the first position. The window 26 when the second main part in this position before absorption liquid is restricted neck 10b of the first main part 10 side protruding elements 24, 25, attached to the connecting links 28, 29 to the rod 21 of the second main part 20 and, in turn, connected at the rear end 22b of the second main part 20 of the first support surface 23a. During the suction box 26 is increased in size until, until it reaches a maximum when the second main part in the second position. The window 26 is then limited by the stopper 21b in the rod 21, the elements 24, 25 and the first support surface 23a which connects the elements 24, 25 at the rear end 22b.

To ensure movement of the second main part 20 relative to the first main part 10 of the latter has at its neck 10b at least two longitudinal grooves 13, 14, running from the neckline 10b to the front end 10A of the cylinder. In these grooves 13, 14 are connecting links 28, 29, which connect the elements 24, 25 of the plunger 22 and the stopper 21b of the shaft 21. Grooves 13, 14 are from the neckline 10b of the cylinder 10 to the place where the connecting links 28, 29 when the piston 21A of the rod 21 in the first position, i.e. in contact with the hole 11.

When the second main part 20 in the first position, i.e. when you are ready to suck or pick up a liquid, the stopper 21b of the shaft 21 is located at a distance from the neckline 10b of the cylinder 10, which corresponds to the length of movement of the second main portion 20 between the first and second the provisions. Once absorption is complete, and prior to the removal of the liquid, that is, when the second main part 20 is in the second position, the stopper 21b of the shaft 21 is located at the same level with the neck 10b of the cylinder 10.

The above-mentioned supporting element 12, which serves as a Central support surface has a through hole 15, the shape of which provides entry in the axial direction of the rod 21, the connecting links 28, 29, the fourth bearing surfaces 27A, 27b and parts of elements 24, 25. A through hole 15 has a lateral abutment edges 15A, which serve to hold the elements 24, 25 in place.

To translate the second main part from the second position to the first position, i.e. before removal of the fluid contained in the syringe, you must place your fingers on the third support surface 23b. Therefore, the distance between this abutment surface 23b and the front end 22A of the plunger 22 is such that the user can place a finger on each side of the syringe.

The syringe, in particular, is used for taking blood, so when you need to pierce a vein, it is necessary to hold the finger of one hand, while with the other hand you can use a syringe to suction or removal of the blood, and removal or introduction of drugs.

To use the syringe for taking fluid must be located in order to revive the hole 11 of the first main part 10 in running contact with the fluid and install the stem 21 in the first position. Once this is done, the fingers should be positioned on different surfaces of the syringe so that the thumb was in the window 26 is limited by a stopper 21b of the shaft 21, the elements 24, 25 and the first support surface 23a located at the rear end 22b of the plunger 22, while two fingers of the same hand must be placed on the fourth support surface 27A, 27b. To start suction using a syringe, you need to press with your thumb on the second bearing surface 12A in the first axial direction; and simultaneously you need to press two fingers of the same hand on the fourth support surface 27A, 27b in the second axial direction D opposite to the first axial direction, to move the second main portion 22 from the first position to the second position.

At this step, the stopper 21b of the shaft 21 prevents the filling of the syringe, exceeding its maximum capacity, as at the end of operation of the suction stopper 21b comes into contact with the thumb inserted in the window 26 and positioned on the second support surface 12A.

In addition to this measure, which prevents removal of the rod 21 of the cylinder 10, on the inner surface of the cylinder 10 near its neck 10b, a raised ring 17 which serves as a barrier that impedes the extraction of the rod 21 of the cylinder 10.

For deleted what I fluid previously entered into the syringe, it is necessary to place the thumb on the first support surface 23a, and two fingers of the same hand on the third support surface 23b. As soon as the fingers are positioned on the syringe and the hole 11 is placed over the reservoir or tube for receiving the contents of the syringe with your thumb to press in the first axial direction, and the other fingers to press in the second axial direction, opposite the first axial direction, to move the second main portion 22 from the second position to the first position.

To perform the preceding actions is stable, secure and simple way with the use of only one arm, the syringe should have a specific and distinctive design, with the pressure of the fingers on the syringe operates in such a way that the direction of the applied force coincides with the direction of movement of the piston in one direction or another depending on how the move is performed, for suction or removal of fluid.

The invention within its scope in practice can be implemented in other embodiments, differing only in detail from the scenarios presented above only as an example.
