Medical device for preventing puncture wound by needle

Abstract

The invention discloses a medical needle stick injury preventing device, which is characterized in that: an outer shell is internally provided with a lock catch; the lock catch is internally provided with a limit stop which is provided with a through hole used for the passing-through of a needle tube; the needle tube is provided with a lug boss; the inner wall of the outer shell is provided with a concave groove; the front end of the outer shell is provided with a lug boss; the lock catch is internally provided with an empty cavity used for containing the limit stop; the surface of the lock catch is provided with a convex piece; the rear end of the lock catch is provided with a base body; the inner wall of the base body is provided with a concave and convex part; the surface of the limit stop is provided with a concave and convex part; the front end of the lock catch has two spring plates in shape of '7'. Due to that the needle stick injury preventing device is additionally arranged on the invention, the lock catch is arranged inside the outer shell, and the limit stop is arranged inside the lock catch, when in use and when the normal puncture operation of infusion and injection is completed, medical staff pull out the needle tube and move the base of the needle tube, and put the tip of the needle tube into the lock catch of the needle stick injury preventing device; the function of the lock catch ensures the needle tip does not extend out of the lock catch and the outer shell, thus preventing needle stick injuries and avoiding the danger of inflection of the medical staff due to the needle stick injury; in addition, the medical needle stick injury preventing device has the advantages of simple structure and convenient operation.

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 ...
