16 15195 П in 11 10 ua.za rfit "tir.rif, 1 7 13 In Fig. 1 I114 The invention relates to medical technology, namely to devices for administering drugs, in particular syringes. A syringe is known which contains a cylinder, inside of which a piston and needle holder fl are placed. However, in this syringe it is impossible to create dosage accuracy. A syringe is known that contains a cylinder inside which a piston with a stem is placed, an ampoule with medicine, and also a needle holder, one of which parts is cylindrical (2}. The disadvantage of this syringe is that it takes a certain time to change the ampoule, which is not fixed in any way, it may be lost. The aim of the invention is to improve the usability of the syringe. Lp achieve the goal in the syringe containing a cylinder, inside which is placed a piston with a stem, an ampoule with medicine, as well as needles the holder, one of the parts of which is cylindrical, the stem is stepped, the lower part, the zipindra has an inwardly directed annular collar to interact with the stem step, the cylindrical part of the needle holder is installed in the cylinder, and the ampoule is placed in it. , and a vial with a notch for interacting with a protrusion.: Fig. 1 shows the proposed syringe, a general view; 2 - part of the syringe during the injection; in fig. 3 - details of the syringe. The syringe contains a cylinder 1, a needle holder 2 consisting of a cylindrical part 3 and a connecting part 4, protrusions 5 and a hollow 6 DbipHU have a replaceable ampoule 7 with a cap 8 and a piston - rod 9, and the rod has a step 10. The lower part of cylinder 1 is made with an inwardly directed collar 11 for engaging with a step 10 of a rod 9, an ampoule is made with a recess 12 and a rod with a protrusion 13 for interacting them. At the connecting part 4 of the needle holder 2, an element 14 is placed in which the needle 15 is installed to puncture the 8 ampoules and the injection needle 16. The syringe is equipped with a needle cap 17. The element 14 has an opening 18 with a protrusion 19 for entering the hollows 6. The syringe operates as follows. The syringe is charged, the ampule 7 is inserted into the cylindrical part 3 of the needle holder 2, and the rod 9 is moved into the cylinder 1 from the side of the larger diameter section until step 10 rests on the annular shoulder 11. Then a larger diameter diameter of the cylinder 1 is inserted into the needle holder 2 and slightly push the rod 9 so that the protrusion 13 enters the recess 12. This prepares the use of the syringe for use (see Fig. 1). To produce the injection, remove the protective cap 17, press the needle 16 in the direction of the needle holder 2, moving the element 14, while the protrusion 19 falls into. a hollow 6, a hollow needle 15 pierces the protective shield 8 of ampoule 7 and reaches the liquid contained in the ampoule. Pressing the rod 9, the liquid is introduced into the injection needle 16 through the hollow needle 15. When the head of the rod 9 presses the bottom of the ampoule 7, the protrusion 13 interacts with the recess 12, the ampoule swings out and the liquid completely leaves the ampoule. If, after making the injection, the rod 9 is retained, while holding the protrusion 13 and the notch in cooperation with each other, the rod 9 will pull the bottom of the ampoule 7 behind it. Thus, you can return the piston to its original position and make sure that the injection is done correctly. The proposed syringe provides the ability to supply the fluid contained in the ampoule into the hollow needle with one push of the injection needle. At the same time, the needle enters the ampoule and the liquid does not spray the other elements of the syringe, which ensures high hygiene, therefore, the syringe can be used after simple charging with its ampoule, which is very convenient in emergency cases outdoors. In addition, fluid leaks are avoided. Thus, the proposed syringe is characterized by exceptional safety and reliability.
