Abstract
The utility model discloses a self-destruction type disposable syringe. The utility model comprises an injection cylinder and an injection rod, wherein, the injection rod is composed of a rod body and a rod head. The front end of the rod head is sheathed with a rubber plug, and the back end is provided with an elastic fin sheet. The rod head and the rod body are connected in a thin neck shape mode. The inner side surface of the front end of the injection cylinder is provided with an annular shoulder. The utility model after use can be self destroyed thoroughly, and the real disposable use can be realized. Simultaneously, the utility model has a safety device and brings convenience for use, packaging, and transportation.
Description
This utility model relates to a kind of medical apparatus and instruments, particularly a kind of re-use preventing once-used syringe.
Disposable syringe is the most frequently used in recent years syringe, and its easy to operate, safe and sanitary is popular.But in use, some user is often reused for cost saving, may make the cross infection of patient's virus, has lost disposable meaning.For this reason, many people have proposed the innovation and creation of relevant re-use preventing once-used syringe.Although these innovation and creation have certain self-destruction effect in varying degrees, often the degree of self-destruction is thorough inadequately, exists the possibility that is re-used.Simultaneously, there are not safety on the syringe, the phenomenon that is destroyed because of maloperation before regular meeting appears at and uses.
The purpose of this utility model is at the problems referred to above, a kind of thorough self-destruction is provided and has the re-use preventing once-used syringe of safety.
This re-use preventing once-used syringe comprises the injection rod in injection tube and the injection tube, injection rod is made up of the body of rod and bar head, the front end of bar head is with rubber stopper, the rear end of bar head is along some elastic fins of horizontally set, be connected for thin neck shape between bar head and the body of rod, injection tube front end inner surface is provided with an annular convex shoulder.When this syringe used, injection rod was pushed ahead by the injection tube rear end, and the injection in the injection tube is entered in the human body.After the bar head of injection rod passed through the annular convex shoulder of injection tube inner surface, because the elastic fin bullet is lived, injection rod just can not back withdraw from, and reaches only expendable purpose.Owing to be connected for thin neck shape between bar head and the body of rod, one pull at the body of rod slightly, just can cause the body of rod to separate with the bar head, make syringe thoroughly ruin ring.
The utility model is described in further detail below in conjunction with embodiment that accompanying drawing provides.
Fig. 1 is the cutaway view of the re-use preventing once-used syringe that provides of this utility model.
Fig. 2 is the sketch map of bar head rear end.
Among the figure, 1, injection tube; 2, injection rod; 3, bar head; 4, the body of rod; 5, rubber stopper; 6, elastic fin; 7, annular convex shoulder; 8, banking stop.
As shown in Figure 1, this type self-destroyed shot device comprises injection tube 1 and injection rod 2, and injection rod 2 is made up of bar head 3 and the body of rod 4 two parts.Bar head 3 front ends are with rubber stopper 5, and the rear end is provided with elastic fin 6.As shown in Figure 2, elastic fin 6 is cross in the present embodiment, has certain radian and elasticity.After elastic fin 6 passed through the annular convex shoulder 7 of injection tube 1 inner surface, injection rod 2 just can not be return.In the present embodiment, except rubber stopper 5, remainder all adopts plastics to make.In addition, the afterbody of the body of rod 4 is provided with banking stop 8, is connected for point between banking stop 8 and the body of rod 4.The effect of banking stop 8 is that the bar head 3 of restriction injection rod 2 passes through annular convex shoulder 7, reaches safety effect.When using this syringe, as long as banking stop 8 is pulled off.
The utility model compared with prior art has following advantages:
1, owing to is connected for thin neck shape between bar head and the body of rod, so real disposable use is accomplished in the thorough self-destruction of this syringe energy.
2, be provided with banking stop on the injection rod, can prevent from using the generation of front maloperation, bring convenience for simultaneously packing, transportation.
