Abstract

The invention provides a self-destructive injector, which belongs to the technical field of medical appliances and is used for solving the problems of liquid medicament pollution and the like caused by self-destruction of the conventional injectors. The self-destructive injector comprises an injection cylinder, an injection rod, a rubber plug and a needle head base, wherein the rubber plug is fixedly connected to the front part of the injection rod; the needle head base is connected to the inner side of the front end of the injection cylinder; the front part of the injection rod is provided with a rod head passing through the rubber plug and extending out of the rubber plug; the needle head base comprises a cylindrical base body I and a cylindrical base body II; a needle head is arranged on the upper part of the base body I; the base body is fixedly connected to the lower part of the base body bi-axially; a clamping structure which can be used for fixedly connecting the base body II with the inner side of the front end of the injection cylinder axially is arranged between the base body II and the inner side of the front end of the injection cylinder; the base body I is fixed circumferentially with the inner side of the front end of the injection cylinder; and the inner side of the base body II is provided with a positioning part which can be fixed circumferentially with the rod head. The self-destructive injector has the advantages of simple structure, convenience in self-destruction and the like.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and relates to a syringe, in particular to a self-destructing syringe. Background technique [0002] Currently, syringes are the most commonly used and one of the most used medical devices. In recent years, in order to control iatrogenic infectious diseases and avoid adverse consequences such as cross-infection, disposable sterile syringes have been widely used. However, the existing disposable syringes all have defects such as being intact after use and still being reusable and having no safety device, and the needle is exposed after injection. Repeated use after disinfection can easily cause virus transmission and cross-infection; on the other hand, the needles after injection are still outside. Inadvertently stabbing medical staff also often occurs, and cross-infection of germs will inevitably occur. [0003] For this reason, people have devised various self-destructing syringes. ...
