Anti-stabbing syringe and self-destruction method thereof

Abstract

The invention discloses an anti-stabbing syringe and a self-destruction method thereof, and relates to the technical field of medical supplies. An anti-stabbing syringe comprises a needle tube, a push-pull rod, a needle seat, a needle head and a needle sleeve. A normal connection state and a destroy connection state exist between the needle sleeve and the needle seat; in a normal connection state, the needle sleeve is sleeved into the needle head and the needle seat through the opening and is in screwed fit with the external thread of the needle seat through the internal thread, and the two buckles of the needle sleeve are respectively opposite to the two ports of the groove of the needle seat; and in a connection destroying state, the needle sleeve is sleeved into the needle head and the needle seat through the opening, and the internal thread of the needle sleeve integrally crosses the external thread of the needle seat or partially crosses the external thread of the needle seat and is respectively clamped into the two ports of the groove of the needle seat through the two buckles. The needle sleeve has the advantages that the mounting and dismounting mode of the needle sleeve is changed from traditional'plugging 'into'screwing-in and screwing-out', only radial rotating force needs to be provided when the needle sleeve is dismounted, pulling with force is not needed, and the needle stick injury caused by hand rebound when the needle sleeve is pulled out is effectively avoided.

Description

technical field [0001] The invention relates to the technical field of medical supplies, in particular to an anti-stab syringe and a self-destruction method thereof. Background technique [0002] Syringes are common medical supplies. There is a risk of needle-stick injuries during use of syringes. Needle-stick injuries are the main way to cause occupational infections. As the infection rate of blood-borne diseases continues to rise in recent years, attention should be paid to and prevention of needle-stick injuries Very important. [0003] The structure of the existing syringe is as Figure 9-11 As shown, it includes a syringe 6, a piston rod 7, a coupling seat 8, a needle head and a needle cap 9; the interior of the syringe 6 is provided with an inner cavity for containing liquid medicine, one end of the syringe 6 is provided with an installation port, and the other end is provided with a liquid medicine outlet; One end of the piston rod 7 is movably installed in the inner...

AI Technical Summary

Problems solved by technology

[0009] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a stab-proof syringe and its self-destruction method, which solves the difficulty of returning the needle cap of the existing syringe with one hand, and the existence of stab wounds when the needle cap is pulled out. Risks, it is difficult to pull out the connecting seat, needle and needle cap together, and it is necessary to rely on the sharps box to destroy the needle
