Syringe needle cap fixing device

Abstract

The invention discloses a syringe needle cap fixing device in the field of medical instruments. The syringe needle cap fixing device includes a fixing frame and a C-shaped bayonet arranged on the fixing frame; an annular groove is arranged at the middle of the inner side of the C-shaped bayonet; the inner diameter of the C-shaped bayonet is the same as the outer diameter of the middle and upper portions of the syringe needle cap; the opening of the C-shaped bayonet is larger than the outer diameter of the syringe needle handle; and the inner diameter of the annular groove is the same as the outer diameter of a ring of protrusion at the opening of the syringe needle cap. The beneficial effects of the syringe needle cap fixing device are as follows: the C-shaped bayonet with the annular groove is arranged, therefore, when removing the cap, the needle cap is inserted from top to bottom, the annular groove is used for locking the protrusion at the opening of the needle cap, and then the cap is removed; and when sleeve back, the syringe needle is inserted into the needle cap, and then the syringe needle is forced downward so that the needle cap is separated from the annular groove and then taken out from the opening of the C-shaped bayonet to complete the sleeve back operation; and therefore, the whole process is convenient and quick, the efficiency of medical staff to take caps andreturn caps with one hand is improved, and the risk of hands being injured by needles is effectively avoided.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a syringe needle cap fixing device. Background technique [0002] At present, medical staff generally require one-handed operation when taking medicine and injecting with a syringe, and one of the more troublesome steps is taking and returning the needle cap of the syringe. It is relatively easy to remove the sleeve, just use your thumb and forefinger to peel it off, but it is not easy to operate when returning the sleeve, because the needle cap is generally in a flat state after being removed, and it is difficult to pick up the needle cap with one hand. Cause needle stick injury, disease transmission and other hazards, increasing the difficulty and danger of medical operations. Contents of the invention [0003] In order to overcome the above-mentioned disadvantages in the existing one-handed operation for taking and returning the cover, the technical problem to be solved by th...
