Abstract
The utility model relates to medical equipment, in particular to a hypodermic syringe which comprises a needle cylinder, a piston and a rubber plug, wherein the piston can slide in the needle cylinder; the rubber plug is fixed at the top end of the piston; the rubber plug is adaptive to the shape of the end part of the needle cylinder; latches are arranged at the top end in the needle cylinder; angles are formed between the latches and the wall of the needle cylinder; and necks adaptive to the latches are arranged at the top end of the rubber plug. With the adoption of the structure, when the rubber plug is pushed forward to the latches by the piston, the latches enter the necks along the walls of the necks so as to clamp the rubber plug and the piston, so that the hypodermic syringe cannot be used again. The whole disposable hypodermic syringe is simple in structure and convenient in operation.
Description
Technical field
This utility model 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
This utility model technical issues that need to address provide a kind of disposable syringe simple in structure.
For solving above-mentioned technical problem; The syringe of this utility model 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 this utility model is done further detailed explanation.
Fig. 1 is the structural representation of this utility model syringe.
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.
