Disposable syringe capable of protecting needle and preventing needle-stick injury

Abstract

The invention discloses a disposable syringe capable of protecting needle and preventing needle-stick injury. The disposable syringe is composed of an injector, a transparent sleeve and an elastic clip, wherein a screw thread is formed in the barrel body of the syringe; a strip-shaped groove is formed in the top section of the transparent sleeve; an inner screw thread is formed in the inner wall of the lower end of the transparent sleeve; the inner diameter of the upper end of the transparent sleeve is more than the outer diameter of a needle bolt; the transparent sleeve covers the syringe and is in threaded connection to the barrel body of the syringe; the transparent sleeve is longer than the syringe; the position of the strip-shaped groove of the transparent sleeve is in correspondence to the needle bolt; the chuck of the elastic clip is located inside the transparent sleeve and is in correspondence to the periphery of the needle bolt; and the handle of the elastic clip extends out of the strip-shaped groove. The disposable syringe disclosed by the invention can be used for avoiding relative contact between fingers of a user and needle tip from medicine suction until to the end of injection, so as to effectively protect doctors from danger of needle-stick injury when returning a needle cap and processing sharp instrument; therefore, the occupational safety of doctors is guaranteed.

Description

technical field [0001] The invention relates to a disposable syringe for needle protection and stab wound prevention. Background technique [0002] Medical staff is a high-risk group of occupational exposure to blood-borne diseases. Due to the high work intensity and tight time, they are too fast when returning the needle cap, which is easy to stab their fingers; In order to save time, medical personnel directly remove with hands or scissors, which is very likely to accidentally injure fingers. [0003] Needlestick injury or sharp instrument injury is the most common occupational injury for nurses, and the infection caused by skin puncture accounted for 84.2%. In order to maintain the occupational safety of medical staff and effectively prevent medical staff from being infected with HIV through occupational exposure at work, the "Guiding Principles for the Prevention of Occupational Exposure to HIV for Medical Staff" stipulates that medical staff are prohibited from re-inse...
