Abstract
The invention relates to a medical apparatus and instrument, in particular to an injector, which comprises a needle cylinder, a piston and a rubber plug which can slide in the needle cylinder, wherein the rubber plug is fixed to the top end of the piston; the shape of the rubber plug corresponds to that of the end part of the needle cylinder; a latch is arranged at the top end inside the needle cylinder and forms an angle with a needle cylinder wall; and a clamping groove which corresponds to the latch is formed at the top end of the rubber plug. After the structure is used, and when the piston pushes the rubber plug forwards to the latch, the latch enters the clamping groove along a clamping groove wall to clamp the positions of the rubber plug and the piston, so that the injector cannot be recycled. The disposable injector has a simple structure and is convenient to operate.
Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, particularly a kind of syringe.
Background technology
Many times need disposable syringe in the modern medical service, for example when vaccinate or infectable infection class medicine.
Chinese invention patent ublic specification of application CN 1795021A discloses a kind of disposable syringe.This disposable syringe comprises: syringe, its both ends open; Take over, it inserts a side of this syringe; Insertion tube during it inserts and should take over, and allows this adapter to contact with the inner periphery of this syringe is airtight; And piston, it inserts in this syringe.Though this disposable syringe effect aspect disposable safety is obvious, the complex structure of this disposable syringe, cost of manufacture is high.
Summary of the invention
The technical issues that need to address of the present invention provide a kind of disposable syringe simple in structure.
For solving above-mentioned technical problem; Syringe of the present invention comprises syringe, the piston that can in syringe, slide and plug; Said plug is fixed on the top of piston; The end shape of said plug and syringe adapts, and said syringe inner tip is provided with latch, said latch and needle cylinder wall angulation; Said plug top is provided with the draw-in groove that adapts with latch.
Be stained with the air adsorption layer on the said plug.
After adopting said structure, when piston was pushed ahead latch with plug, latch can enter into latch along the draw-in groove wall, and plug and position of piston are blocked, and so just cannot reuse.Whole disposable syringe simple in structure, easy to operate.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is done further detailed explanation.
Fig. 1 is the structural representation of syringe of the present invention.
Among the figure: 1 is syringe, and 2 is plug, and 3 is piston, and 4 is latch, and 5 is draw-in groove, and 6 is the air adsorption layer
The specific embodiment
Syringe as shown in Figure 1 comprises syringe 1, the piston 3 and the plug 2 that can in syringe 1, slide, and said plug 2 is fixed on the top of piston 3, and said plug 2 adapts with the end shape of syringe 1, can plug 2 be advanced to the top of syringe 1 like this.Said syringe 1 inner tip is provided with latch 4, said latch 4 and syringe 1 wall angulation; Said plug 2 tops are provided with the draw-in groove 5 that adapts with latch 4; When like this piston 3 being advanced to the position of syringe top latch 4; Latch 4 can be stuck in the draw-in groove along draw-in groove 5 walls, so just cannot piston 3 be extracted out from syringe 1 again, has reached disposable purpose.
Be stained with air adsorption layer 6 on the said plug 2, air adsorption layer 6 can well absorb the air in the medicinal liquid, be inject more safe.
Claims (2)
1. syringe; Comprise syringe, the piston that can in syringe, slide and plug, said plug is fixed on the top of piston, and the end shape of said plug and syringe adapts; It is characterized in that: said syringe inner tip is provided with latch, said latch and needle cylinder wall angulation; Said plug top is provided with the draw-in groove that adapts with latch.
