Description
Technical field
A kind of double push rod self-destructive syringes are the utility model is related to, belong to medical instruments field.
Background technology
Disposable sterilized injector is a kind of new type medical equipment that China introduces the eighties in last century, it is avoided that intersecting
The adverse consequences that infection, iatrogenic infectious disease etc. are brought, instead of traditional glass syringe and has been widely used.It is but existing
Outward appearance still remains intact some disposable sterilized injectors after use, easily by some illegal retailers purchase, peddle and cause
Secondary or be used for multiple times, this measure easily causes the propagation and cross-infection of virus, and consequence is extremely serious.
At present, there are some destructive syringes in the market, and destructive syringe is to prevent recycling once
Property syringe products, it with technological means eliminate disposable syringe backflow market, reuse possibility.Use at present
Needle retraction type self-destructive syringe, it the front end of syringe needle and push rod set locking device, after the completion of injection, locking dress
Startup is put, pumpback push rod can make syringe needle be retracted syringe.It is not only avoided that cross-infection, while can reduce the useless note of recycling
Needle stick injury during emitter, further protect the safety of patient and medical personnel.
Although above-mentioned needle retraction type self-destructive syringe largely solves disposable syringe and recycled
The problem of, but such a syringe still has some problems, medical personnel when habituation promote push rod forward, if one is small
Push rod is pushed away forward by the heart, will start locking device, syringe will self-destruction, easily cause waste.Therefore currently on the market
Still lack a kind of more reasonably destructive syringe of needle retraction type.
Utility model content
The purpose of this utility model is solve above-mentioned the deficiencies in the prior art, proposes a kind of double push rod self-distroyable disposable injections
