Anti-needle stick device for medical use

Abstract

The invention discloses a needle stab wound prevention device for medical use, which is characterized in that: a lock is provided in the casing, a block is arranged in the lock, and the block has a through hole for the needle tube to pass through; the needle tube is provided with a convex There is a groove on the inner wall of the shell, a boss on the front end of the shell, a cavity that can accommodate the stopper in the lock, a convex piece on the surface of the lock, and a seat at the rear end of the lock. , the inner wall of the seat is provided with concave and convex parts, the surface of the block is provided with convex and concave parts, and the front end of the lock has two "7" shaped shrapnel. Due to the addition of the anti-needle stabbing device, the present invention is provided with a lock in the shell, and a stopper is arranged in the lock. When in use, after the normal infusion and injection puncture operation is completed, the medical staff pulls out the needle tube, And move the needle tube seat so that the needle tip of the needle tube enters the lock of the anti-needle stick device. Due to the function of the lock, the needle tip will not protrude out of the lock and the shell, thereby preventing needle stick injuries and preventing medical staff from being stabbed by needles. The risk of infection due to injury, and the present invention is simple in structure and easy to use.

Description

Technical field: [0001] The invention relates to the technical field of medical injection and transfusion puncture, in particular to an anti-needle stab injury device for indwelling needles and other syringes and infusion sets. Background technique: [0002] Most of the currently used indwelling needles or other syringes and infusion sets do not have safety protection devices to prevent needlestick injuries. Although they are handled with great care, according to the available incomplete statistical data, when medical staff handle these needles and infusion containers, they are injured by needles more than once a year on average. However, there is a risk of infection for every 6 stab wounds on average. If the patient is suffering from an infectious disease, the risk of infection will increase greatly after the needle pulled out from the patient punctures the medical staff. Invention content: [0003] The object of the present invention is to provide a kind of anti-needle ...
