Abstract
The utility model relates to a disposable syringe. A push rod is arranged inside an injection cylinder of the utility model. The front end of the push rod is provided with a rod head, and the back end is provided with a rod body. Rubber layers are attached to the front end and the side surface of the rod head. The back end of the rod head is connected with an elastic blocking sheet. The inner side of the front end of the injection cylinder is provided with a convex ring. When the push rod is pushed to the front end of the injection cylinder, the elastic blocking sheet can be blocked by the convex ring so that the push rod can not be retreated. Thereby, the utility model can be only used once.
Description
This utility model belongs to technical field of medical instruments.
Existing disposable syringe, himself is still excellent owing to use the back, be difficult to the disposable effect that reaches real, thereby result of use is poor.
The purpose of this utility model is design a kind of result of use good disposable syringe, and this syringe is after use, because the structure of himself changes, thereby can not reuse.
The utlity model has an injection tube, an end is equipped with syringe needle, and push rod is installed in the injection tube, and push rod is made of the bar head and the body of rod, and the two connects by a fixed axis, and an end of the body of rod stretches out outside the injection tube, is connected with antifouling film between the outer end of push rod and the injection tube; Be connected with rubber layer on the front end of bar head and the side, the rear end is connected with a recurvate elastic block piece; Be provided with a convex ring in the inboard of injection tube front end;
This utility model in use, when push rod was pushed into the front end of injection tube, elastic block piece can be blocked by bulge loop, and push rod can not be extracted, thereby this utility model can only disposablely be used, result of use is good.
Accompanying drawing is the structural representation of this utility model embodiment.By accompanying drawing as can be seen, the utlity model has an injection tube 1, syringe needle 2 is installed at the one end.In the injection tube 1 push rod is installed, this push rod is made of the bar head 3 and the body of rod 4, and the two connects by a fixed axis 5, and an end of the body of rod 4 stretches out outside the injection tube 1, is connected with antifouling film 8 between the outer end of push rod and injection tube 1, and this antifouling film 8 can use plastic sheeting.Be connected with rubber layer on the front end of bar head 3 and the side, the rear end is connected with a recurvate elastic block piece 6.Be provided with a convex ring 7 in the inboard of injection tube 1 front end.This utility model uses and once can damage, and has fundamentally solved the problem that existing disposable syringe can be used again.
