Abstract
A vaccum self-destruction type disposable injector belongs to the medical treatment apparatus manufacture technical field. A gun head is arranged on the inner wall of the needle tube close to the tip of the pinhead. A thin separation layer is arranged in a piston corresponding with the gun head. A hole is arranged inside the piston and communicated with the thin separation layer. The gun head can be various sharp bodies, such as three-corner knifepoint or shovel. A push rod is used to supply medicine by operators. When the operation is about to end, the thin separation layer on the piston contacts with the gun head and thrusts the thin separation layer. A hole inside the piston enables the piston to perforate from back to forth, and the injector is damaged and can not be used repeatedly. The utility model has the advantages of simple and convenient operation, safe and reliable performance, effective self-destruction for disposable utilization, simple structure and low cost.
Description
Technical field:
This utility model belongs to manufacture technology field of medical appliance, is a kind of syringe.
Background technology:
Injector for medical purpose mainly is made of needle tubing, syringe needle, push rod and piston body, is mainly used in subcutaneous injection, because syringe uses repeatedly and may produce cross infection, generally all adopts disposable syringe at present.And existing disposable syringe is to be processed with the frangibility gap on push rod, after the use, operator fracture push rod, to prevent repeated use, this kind method needs the repeated use of active protection syringe, because a variety of causes, as operator's push rod that in time do not fracture, or subjectively will reuse consciously, then can not reach disposable purpose.
Summary of the invention:
The technical problems to be solved in the utility model is to disclose a kind of disposable syringe that can self-destruction.
The scheme of this utility model technical solution problem is on the termination inwall of the close syringe needle of needle tubing the rifle head to be housed, and there is the leptophragmata layer at the piston body place of rifle head correspondence position, has through hole, through hole to be communicated to leptophragmata layer place in the piston body.Wherein, the rifle head can be various tip shape bodies,, shovel shape etc. pointed as knife with three edges.During use, the operator is by push rod drug delivery forward, when operation closes to an end, the leptophragmata layer contacts with the rifle head on the piston body, and the rifle head punctures the leptophragmata layer, owing in the piston body through hole is arranged, make the piston body front and back connect, syringe suffers passive failure, can not reuse.
This utility model is simple, convenient, and serviceability is safe and reliable, and self-destruction effectively reaches disposable application target, and simple in structure, cost is low.
Description of drawings:
Accompanying drawing is this utility model cutaway view.
The specific embodiment:
This utility model is made of needle tubing 1, syringe needle 2, push rod 3 and piston body 4, on the termination inwall of the close syringe needle 2 of needle tubing 1 rifle head 7 is housed, and there is leptophragmata layer 6 at piston body 4 places of rifle head 7 correspondence positions, and through hole 5 is arranged in the piston body 4, and through hole 5 is communicated to leptophragmata layer 6 place.
Claims (1)
1, a kind of vacuum re-use preventing once-used syringe, be made of needle tubing, syringe needle, push rod and piston body, it is characterized in that: on the termination inwall of the close syringe needle of needle tubing the rifle head is housed, there is the leptophragmata layer at the piston body place of rifle head correspondence position, through hole is arranged in the piston body, and through hole is communicated to leptophragmata layer place.
