Background technique
Syringe is a kind of common medical instruments, by the foraminate syringe of front end band and matching piston core pin
Composition, syringe be used to by a small amount of liquid or its be injected into region that other methods can not approach or taken out from those places
Out, perhaps gas is sucked when core bar is pushed into from syringe front end aperture by liquid or gas liquid when core bar is extracted
It squeezes out, is called injection with this process that syringe and syringe needle extracted or injected gas or liquid, mainly to inject
Medical fluid or drawing liquid.Currently in order to avoid reuse syringe and cause to infect, use disposable syringe more, and existing one
Secondary property syringe, and existing disposable syringe, generally comprise the syringe of hollow structure, set the syringe needle of syringe front end and be set to
The push rod that can be moved forward and backward in syringe, and between syringe and syringe needle it is detachable structure, therefore many people can replace for convenience
Syringe needle continues to use, and undoubtedly leads to the probability of cross-infection, influences people's health.A kind of this problem that can solve now is provided
A kind of disposable syringe.
