Description

The invention relates to medical technology, more specifically to syringes, intended for drugs or strictly metered drugs.

The purpose of the invention is to prevent the illegal use of spice. Fig, 1 shows a syringe; in fig. 2 shows section A-A in FIG. one.

Ipritz with a watchdog. contains capsule 1, nipple 2, adapter 3 with cavity 4, hole 5, gasket 6, glass 7, piston 8 with rod 9 and suction valve 10, washer 11, spring 12, gripper 13, clamp 14, housing 15, tube 16, a cover 17 with a lock 18 and a latch 19, a guide lug 20, a key 21, a needle 22, pins 23 and 24, a flat spring 25, a groove 26, a slot slit 27 and a projection 28 of the lock 18. The output end of the capsule 1 is worn nipple 2, closing outlet. The nipple 2 is fixed using an adapter 3 having a cavity 4, as well as a channel for discharging the preparation. The adapter 3 is screwed onto the adapter 3. In the capsule 1 there is an opening 5 for filling the capsule 1 with the preparation, Sealing gasket 6 provides sealing of the capsule 1, the distal end of the capsule 1 is connected to the glass 7, In the cavity of the capsule 1 there is a curvature 8 with stem 9, B rod body 9 there is a suction valve 10, between the glass 7 and the capsule

11, limiting the stroke of the piston 8, lllTOK 9 is spring-loaded and has a grip 13 for compressing the spring. In. The flange of the cup 7 has a retainer 14 integrated. On the side of the outlet opening, a tube 16 is mounted on the body 15 fixed to the adapter 3, the tube 16 closes the opening 5 to fill the capsule with a medicine. The needle 22 is attached to the outlet opening of the tube 16, the housing 15 is closed by a cover 17 with a lock 18 and a latch 19, the lock 18 is controlled by turning the key 21 and a protrusion 28 interacts with a slot 27 in the rod 9, the latch I9 is spring-loaded with a flat spring 25 and engages with the groove 26 in the housing 15, the coaxiality of the parts during assembly and during operation is provided by pins 23, 24 and the guide bar 20,

The syringe works as follows. To fill the syringe with the drug you need to insert

By turning the key, the pin 21 in 3 amok 18 and 21 open the wing 17, the lock 18 of the lock 18 presses on the spring-loaded (spring 25) slide 19,

5 the latter comes out of the groove 26 and frees the wing 17. Sleep into the bottom 17, fingers are pressed under the grip 13 and the piston 8 is pulled back holding the outflow 9, while in the capsule chamber

fO creates a vacuum, the valve 10 opens, facilitating the movement of the piston 8. In the extreme position, the piston 8 opens the opening 5, Then the tube 16 is removed (the tube 16 and the needle 22 can be sterilized additionally or separately). The drug is introduced through the opening 5, while the air from the capsule cavity goes through the nipple 2 into the atmosphere, the valve 10 is closed. After the cavity of the capsule 1 is filled with the drug, the rod 9 is moved to its original position and secured with latch 14 so that the side surface of the piston overlaps the hole 5, 5, excluding the possibility of illegal (through the hole 5) extraction of the drug. A cover 17 is mounted on the housing 15 in a position fixed by the pin 23,

30 The lock 18 is retracted from the latch 19, releasing the spring 25, the latch 19 enters the groove 26 and secures the cover 17 on the housing 15, the spade of the lock 18 is inserted into the slot of the rod 27, On

Tay housing 15 installed; tube 16 installed;

while the tube 16 closes the hole 5 in the housing 15,

 filled, the spring 12 is cocked, after removing the key 21, the syringe 40 is prepared for storage. Removing the drug through the needle prevents nipple 2.

To perform a subcutaneous injection, use the key 21 to open the rod 9 from the lock 18, insert the needle 22 into the cannula of the housing 15, insert the needle 22 under the skin and press the release button 14, The latch 14 releases the rod 9, which, under the action of spring I2, starts move the piston 8, creating pressure at which the nipple 2 opens and the drug is withdrawn through the needle 22. Stop the process or change the dose

55 cannot be.

Thus, after filling the syringe with a drug, the extraction of the drug is excluded by overlapping the inlet and outlet otter-turn of the key.

stiy. Illegal use of the syringe is excluded, since the movement of the rod 9 is blocked by the lock 18. After removing the lock and pressing the latch button 14, it is impossible to change the dose of the administered medication.

F o r mule of invention I

A syringe comprising a housing, a capsule

with a drug outlet on the front side, a piston with a rod and a guard device, characterized in that, in order to ensure the safety of the drug, the guard device consists of a nipple, a tube, a lock with a latch and a lock with a protrusion, an adapter with a cavity

and a drug exit channel, a cup with a retainer in its flange, and a piston is equipped with a valve, the pump has a slot and is equipped with a spring and a catch, the housing has an opening for inserting the medicine, the capsule at one end connected to the adapter and fixing the nipple that is fitted to the capsule inlet , and on the adapter is fixed

the tube so that the side of the tube closes the opening for the introduction of the drug, while the other end of the capsule is connected to the cup, which is fixed in the body, and the end of the body from the stem side is closed with a hook so that the lock projection interacts with the slot in the stem.
