A sealed cavity is formed in the syringe by the rubber sleeve, so that the medicine is avoided being infected by bacteria which is contacted with a tube wall; and the sterile syringe is simple in structure and lower in cost, and is suitable for common medical institutions.

Description

A kind of asepsis injector

Technical field

This utility model relates to technical field of medical instruments, relates in particular to a kind of asepsis injector.

Background technology

The syringe that uses clinically is divided into glass syringe, disposable syringe and self-destruction syringe at present.The inwall and the external world of glass syringe communicate, and antibacterial is entered in the medicinal liquid, and use repeatedly, easily medicine are infected; Though disposable syringe does not reuse, the same with glass syringe, the inwall and the external world communicate, and easily make the bacterial infection medicine; Self-destruction syringe can be avoided the infection of medicine, but can only use once, generally medicinal liquid need be extracted just can finish back and forth when making up a prescription and make up a prescription, so the range of application limitation of self-destruction syringe is too big.

The utility model content

For overcoming above-mentioned technical problem, this utility model provides a kind of simple in structure, the asepsis injector that can avoid the bacterial infection medicine.

For realizing above-mentioned technical purpose, this utility model is achieved through the following technical solutions: a kind of asepsis injector, comprise a body, be provided with piston in the body, be fixedly connected with piston rod on the piston, the top of piston rod is provided with handle, it is characterized in that: be provided with a rubber sleeve between body and the handle, the two ends of rubber sleeve and body, handle are sealedly and fixedly connected.

This utility model is compared with conventional art, has following beneficial effect: rubber sleeve will form a sealed cavity in the syringe, has avoided antibacterial to infect medicine by the contact tube wall; It is simple in structure, and cost is lower, is fit to general medical institutions and uses.
