[0003] When the neck of the ampoule bottle is broken, glass chippings are inevitably produced, the glass chippings can drop into the bottle body of the ampoule bottle, the medicine in the ampoule bottle is extracted by the injection needle, after muscle injection, the glass chippings cause the occlusion of subcutaneous capillary vessels, and irreversible damage is caused. Meanwhile, when the medicine in the ampoule bottle is extracted by the needle of the syringe, the needle of the syringe is exposed in the air in advance, and the needle of the syringe is easily polluted. SUMMARY
[0004] In view of the above-mentioned deficiencies in the prior art, the utility model provides an ampoule injection filter device for preventing glass chippings produced when the neck of the ampoule bottle is broken from entering the subcutaneous tissue.
[0005] In order to solve the above-mentioned technical problem, the utility model adopts the following technical scheme:
[0006] The ampoule injection filter device includes an ampoule mixing cup, the open end of the ampoule mixing cup is an ampoule insertion end, the other end of the ampoule mixing cup is an empty needle teat connecting end matched with the empty needle teat of the syringe, and a filter membrane is arranged on the inner wall cross section of the ampoule mixing cup and between the ampoule insertion end and the empty needle teat connecting end.
[0007] As a preferred scheme of the utility model, an inner recessed empty needle teat insertion hole is arranged on the inner hole wall of the empty needle teat connecting end in the circumferential direction, and the inner diameter of the empty needle teat insertion hole is matched with the outer diameter of the empty needle teat.
[0008] As a preferred scheme of the utility model, at least two circular ring type clamping grooves are arranged on the inner wall of the ampoule mixing cup close to the ampoule insertion end, the inner diameter of the circular ring type clamping groove close to the port of the ampoule insertion end is greater than the inner diameter of the circular ring type clamping groove away from the port of the ampoule insertion end.
[0009] As a preferred scheme of the utility model, the ampoule mixing cup is made of soft rubber.
[0010] Compared with the prior art, the utility model has the following technical effects:
[0011] 1. Because this utility model has a filter membrane installed on the cross-section of the inner wall of the ampoule mixing cup and located between the ampoule insertion end and the empty needle nipple connection end, and the empty needle nipple connection end of the ampoule mixing cup is connected to the empty needle nipple on the syringe, when the broken ampoule is inserted into the ampoule mixing cup insertion end, and the syringe draws the liquid from the ampoule through the ampoule mixing cup, the filter membrane intercepts all the glass fragments generated when the neck of the ampoule is broken into the ampoule mixing cup, preventing them from entering the syringe. After intramuscular injection, it can effectively prevent the glass fragments generated when the neck of the ampoule is broken from entering the subcutaneous tissue.
[0012] 2. The syringe connects to the ampoule mixing cup via its empty needle tip to draw the medication from the ampoule, instead of using the syringe needle to directly draw the medication from the ampoule. This avoids exposing the syringe needle to the air beforehand and causing needle contamination.
[0013] 3. The inner wall of the ampoule mixing cup has at least two annular slots near the ampoule insertion end, which can accommodate ampoules of different sizes. The ampoule mixing cup is made of soft rubber. When you need to remove or replace the ampoule, simply squeeze the ampoule mixing cup to squeeze the ampoule out of the ampoule mixing cup.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0019] like Figure 1As shown, the ampoule injection filtering device comprises an ampoule mixing cup 1, the open end of the ampoule mixing cup 1 is an ampoule insertion end 2 for inserting an ampoule 9. The other end of the ampoule mixing cup 1 is a hollow needle nipple connecting end 5 for connecting with a hollow needle nipple 4 of a syringe 3. A filtering membrane 6 is arranged on the inner wall cross section of the ampoule mixing cup 1 between the ampoule insertion end 2 and the hollow needle nipple connecting end 5. An inner recessed hollow needle nipple insertion hole 7 is arranged on the inner hole wall of the hollow needle nipple connecting end 5 in the circumferential direction, and the inner diameter of the hollow needle nipple insertion hole 7 matches the outer diameter of the hollow needle nipple 4.
[0020] When using the ampoule injection filtering device, as shown, Figure 2 first, the hollow needle nipple connecting end 5 of the ampoule mixing cup 1 is connected with the hollow needle nipple 4 of the syringe 3, that is, the hollow needle nipple 4 of the syringe 3 is inserted into the hollow needle nipple insertion hole 7 in the hollow needle nipple connecting end 5, and the hollow needle nipple 4 and the hollow needle nipple connecting end 5 are sealed and connected. Then, the broken ampoule 9 is inserted into the ampoule insertion end 2 of the ampoule mixing cup, and the assembled structure is as shown in Figure 3 As the filtering membrane 6 is arranged on the inner wall cross section of the ampoule mixing cup 1 between the ampoule insertion end 2 and the hollow needle nipple connecting end 5, when the syringe 3 draws the liquid medicine in the ampoule 9 through the ampoule mixing cup 1, the filtering membrane 6 completely intercepts the glass chips generated when the ampoule 9 is broken in the ampoule mixing cup 1, avoiding entering the syringe 3. After intramuscular injection, the glass chips generated when the ampoule 9 is broken can be effectively prevented from entering the subcutaneous tissue to cause capillary blockage and irreversible damage. The syringe 3 draws the liquid medicine in the ampoule 9 through the connection between the hollow needle nipple 4 on the syringe 3 and the hollow needle nipple connecting end 5 on the ampoule mixing cup 1. After the liquid medicine in the ampoule 9 is completely drawn into the syringe 3 through the ampoule mixing cup 1, the ampoule mixing cup 1 is removed from the hollow needle nipple 4 of the syringe 3. Finally, the needle of the syringe is installed on the hollow needle nipple 4 of the syringe 3, instead of directly using the needle of the syringe to draw the liquid medicine in the ampoule 9, effectively avoiding the needle of the syringe being exposed to the air in advance and causing the needle of the syringe to be contaminated.
