(57) Abstract:

The invention is intended for use in medicine for injection. The technical result - the possibility of determining the value last entered the dose and the time of its introduction for patients with diabetes. The syringe has a mechanism installation of the dose button that can be actuated to introduce the prescribed dose, switch, actuated at the same time between the beginning and end of injection, and electronic performance parameters such as the amount of the prescribed dose and the last of the administered dose. The syringe has a stopwatch, which is reset and is started when a trigger switch. State the functions of hours submitted electronically and together with the electronic representation of the parameters is reproduced on the display containing a number of segments, forming a circle. 7 C.p. f-crystals, 6 ill.

The invention concerns a syringe with the installation mechanism of the dose button, valid for injection movement with the aim of introducing the prescribed dose, switch, current, when an injection at the beginning or at the completion of the injection, or at the same time between the beginning and end of the injection, the military dose.

Electronic submission is usually in the form of electronic display that shows the number indicating the number of international units of medication in the device and the most recent input dose. However, to show the value of people with impaired vision to electronic submission, you can attract attention by speech patterns, which announces the number instead of their display. Alternatively, the number can also be converted electronic or electro-mechanical means in tactile code or number may be communicated via a suitable interface to represent any external means, such as television screens, monitors, personal computers, etc.

Diabetics who must often introduce yourself insulin may want to know not only the value of the last input dose, but also how much time has passed since then, as was done last injection.

From the document EP 87491 known set with storage box for vials of insulin and syringes, this kit is equipped with a timer, which allows you to manually set the time for the last injection. Next, you can set the hour for the next injectie injection. However, in a world where people can in a short time to fly from one time zone to another, and watch in time zones even can be translated from summer to winter time, the reference of the hour is uncertain. Here is more adequate account in reverse order, but has the drawback consisting in the fact that if You are not ready to take the shot immediately when the alarm sounds, You must manipulate the new expense of time, for example on what interval was set the alarm and how much time has passed from sound the alarm before performing an actual injection.

From the patent DE 3824217 known syringe tool, designed for installation and dose containing a timer and an electronic Central unit, connected with the installation tool and dose and timer, and having a storage device in which is stored the time and size, at least, the most recent of the group and of the administered dose. The syringe also has a display device associated with the Central unit for displaying stored in a storage device data or data calculated on the basis of data stored in said data storage device. Show calculated data may be the and, with which these problems will be overcome.

Another object of the invention is the obtaining of the relevant parameters submitted electronically, which allows the representation of these parameters in any preferred manner. When selecting liquid crystal display numbers can be arbitrarily large, since their size does not depend on the magnitude of the mechanical movement, introducing the displayed parameter. Information can be converted into audio or Braille and can be transferred to external displays.

The problem is solved syringe with the installation mechanism of the dose button operable to move the injection for injecting the set dose, the switch acting in the beginning or at the completion of the injection, or at the same time between the beginning and end of injection, and electronic submission of relevant parameters, such as the set dose and the last entered dose, this syringe in accordance with the invention is distinguished in that it includes a stopwatch, which recovers and runs when the switch is actuated, and the status of the function of the stopwatch is considered as the last action of the switch, that is, from the last injection, the user can have a comprehensive idea of the time elapsed after the last injection and the volume of this last injection. Thus, the user can set the following dose with respect to these parameters.

When in accordance with the invention, the stopwatch is reset and started when the actuation of the switch, for example, when injecting the move button is completed, the clock will automatically start timing when the injection.

According to a variant embodiment of the invention the state of the stopwatch immediately after actuation of the switch is displayed by indicating the number of seconds after the mentioned actions. This may allow the user to hold the inserted needle for injection for some seconds after pressing the button to its original position, which is desirable for the ability of fluid to adapt in the tissue before the needle is removed, since the liquid can flow through the wound left by the needle, so that the body absorbed dose is less than was intended, and it is desirable to enable pogoditsa 6 seconds.

From the application WO 90/09202 known syringe, in which the timer counts down the seconds passing from the start of injection until the completion of the injection. However, this time is less important and it is recommended that the user operated the speed of injection, because he can feel, if the liquid is introduced faster than it can absorb the fabric.

According to a variant implementation of the syringe in accordance with the invention, an electronic representation of a stopwatch is a digital display on which is displayed a number of segments, forming a circle, with each of the segments is activated during each hour elapsed from the completion of injection, that is, after it has been powered switch.

Within the first seconds of running, the electronic display can be used to guide the patient to hold the needle entered within some seconds after completion of injection of the movement buttons. This guide is obtained by incorporating one or more segments in the second, taking place immediately after the injection movement of the button until all the segments of the dial will not turn on. After that, all the segments are disconnected and EIT is about is, after executing the last injection.

According to a variant of the invention, the electronic display may contain twelve segments of a circle, forming a clock and, when the segments include one hour after the last actuation of the switch, this is done in such sequence that the segment between the twelve o'clock position and the position of one hour was included after one hour, the segment between the position of one hour and the position of two hours then turn on after two hours and so on.

The same clock can be used to progress the first few seconds after actuation of the switch with the difference that two segments are included within each second that passed after setting the button to its original position. First get the two segments can be segments between five and six o'clock positions and between six and seven provisions, the following two segments can be segments between seven - and eight-hour and four - and five-hour regulations and so forth so that all the segments on the dial are included for six seconds, starting from the lower part of the dial and spreading cha is a quiet first seconds of running, they turn off and then re-run one hour, since the actuation of the switch.

According to a variant implementation of the syringe according to the invention the said syringe may be equipped with memory for storing data containing the dimensions of a quantity previously entered doses and intervals between doses and the type of insulin used for injection.

Below the invention will be described with reference to the drawings, where

in Fig.1 depicts a screen in which none of the elements of the display are not included;

in Fig. 2 is shown in Fig.1 display during control include all of the elements of the display;

in Fig.3 - display of Fig.1, showing the size of the prescribed dose;

in Fig.4 - the display of Fig.1 five seconds after pressing the button to its original position;

in Fig.5 display of Fig.1 immediately after the injection;

in Fig.6 is shown in Fig.1 display four hours after entering 20 units of medication.

In Fig. 1 shows an implementation option window display screen that displays the electronic representation of the parameters, such as the set dose, the last entered dose, and the state corresponding to the invention of the stopwatch. None of the elements of the display not including the term or when the display is off during storage, to save battery capacity.

When the device lead to readiness for use, for example, by removing the protective cap, it is possible to perform the function of short-term tests, which included all of the elements of the display to make sure they all work. This state is shown in Fig.2. The display elements contain the numbers 1 to indicate prescribed doses, the segments 2 for indicating elapsed time and dial that displays the range of 3 to indicate that the stopwatch counts down the clock.

When driven installation mechanism dose syringe, the display changes and appears on the display shown in Fig.3, the image displays the value of the prescribed dose in the form of a number representing the number of installed units. Until the injection has not yet been started, the set dose can be changed.

After installing dose needle of the syringe is injected into the subcutaneous tissue of the user and click injections in the initial position. When the complete button is pressed in the initial position actuates the switch, and this switch actuates a stopwatch, counting the hours passing after completion of the above-mentioned push of a button. In wereinjected was completed, to give the user a guarantee that the needle stays put for a few seconds after the end of injection. It is recommended to leave the needle in the tissue within 5-10 seconds after completion of injection to ensure that you have entered the full dose and that the liquid was spread on the fabric so that it will not come out through the wound from the needle. In Fig.4 shows the display after five seconds, when included two segments of the display in the second last after clicking in the initial position, that is accepted as fact, showing that the introduction of the injection is finished. The inclusion of the segments starts from the lower part of the dial and pushed two segments per second on each side of the dial. It is shown in Fig.4 series connection is illustrated by the use of light-grey color for the most recent included segments. After six seconds, all segments of the dial turned on and the image is now changed to the state shown in Fig.5. Here are included the range of 3 to show that the stopwatch, which believes hours from the end of the injection started, but since it took less than an hour, no segments are not yet included. Considered the image now shows the value of the most recent and is Diniz drugs.

The first stopwatch is running until the next actuation mechanism installation doses. The mechanism installation of dose changes the display as shown in Fig. 3, only the image will show the number "20" and the value now of the prescribed dose.

When installing the protective cap, the display turns off, and when the cap is removed, the display turns on. When the display is turned on, it briefly shows an image of the test in accordance with Fig.2 and then changes the display image shown in Fig.6, representing the last administered dose and the number of hours elapsed after the injection.
