Description
Technical field
This utility model belongs to technical field of medical instruments, more specifically relates to a kind of retracting type self-destroyed syringe.
Background technology
In the process of medical treatment, syringe is the most frequently used medical instruments of doctor, usual syringe construction is all that needle mount is directly enclosed within the conical pipe of syringe jacket front end, after once, needle exchange head is used again, syringe jacket reuses again, probably stabs hospitalized patients, cause the hidden danger such as cross infection with the syringe needle crossed because deal with improperly.
In recent years in order to control iatrogenic infectious disease, avoiding the adverse consequencess such as cross infection, generally using disposable sterilized injector.But existing disposable syringe holds and so remains intact after using, use rear complete syringe, can be utilized by some lawless persons, even obsolete disposable syringe be reused without sterilization, this very easily causes propagation and the cross infection of virus, in addition, after syringe uses, outside syringe needle is still trapped in, the personnel of such syringe needle meeting scraping contact, inevitably there will be the cross infection of pathogenic bacteria, simultaneously the exposing of syringe needle, also make troubles to the carrying of syringe and destroying.
China Patent No. ZL201220347982.8 discloses a kind of retracting type self-destroyed syringe, comprise an inside for hollow syringe, the push rod that can slide in syringe and be connected in the needle stand of syringe front end, back end of syringe is provided with syringe ear seat, described push rod front end is provided with plug and push rod front end is fixed with conehead, a syringe needle is equipped with in described needle stand front end, it is characterized in that, annular ring is provided with bottom described needle stand, described annular ring is provided with the inner cone for hollow, there is in the middle part of described needle stand the cavity be connected with cone inside, described cone is bored sheet by two panels and is surrounded, wherein a slice cone sheet height in described two panels cone sheet is higher than another sheet cone sheet, described cone rearward end is greater than cone leading section, the conehead of described push rod front end can insert the cavity of above-mentioned needle stand inside.
Although above-mentioned retracting type self-destroyed syringe largely solves the problem that syringe is reused, but this syringe is in the process of transporting and use, because improper operation or maloperation also can cause scraping contact personnel, cause cross infection, such as, in use, nurse can habitually push pin head before the injection, push rod moves ahead, the conehead of push rod front end returns the cavity inserting needle stand inside, such conehead is locked in needle stand, and when pulling open push rod, syringe needle can retracting type self-destruction, and above operation causes syringe not use.
Thus be badly in need of badly improving of the prior art.
Utility model content
