Embodiment Construction

[0012] The present invention will be further described below in conjunction with accompanying drawing:

[0013] As shown in Figure 1, the disposable anti-stab injection needle, the base 1 end of the needle 3 is fixed with a retractable hollow cap body made of plastic, the retractable hollow cap body is made of 3 to 4 sleeve tubes 2 successively, and the hollow A ring-shaped hollow cavity 8 is arranged on the top of the innermost casing of the cap body. The middle of the hollow cavity 8 is a needle penetration hole 4, and two piston holes (piston buckle 5 and piston buckle 6) are symmetrically arranged on the inner wall. , the outer side of the hollow cavity is connected with an annular piston buckle 7, and the piston buckle 7 is fastened in the piston hole 6 that does not prevent the needle 3 from passing through the needle penetration hole 4 in the initial state.

[0014] Sleeve connections form a scalable structure, and there are many possible implementations in the prior ar...

Abstract

The present invention belongs to the field of medical article, and is especially one kind of disposable stab-preventing syringe cap, which is one telescopic hollow cap fixed onto the seat of the syringe and comprising several successively interlinked sleeves and has one inside ring to form a cavity and with two piston holes in the side wall and one ring piston buckle outside the cavity. The present invention has the advantages including capacity of avoiding stab by the used syringe, no contamination, possibility of being separated from the syringe tube, etc.

Description

technical field [0001] The invention relates to a disposable anti-stab injection needle, which belongs to the field of medical appliances. Background technique [0002] After the disposable needle of the syringe is used, in order to prevent and isolate infection, the syringe and needle need to be disposed of intensively. Nursing personnel need to separate the needle from the syringe, and then place the needle in other penetration-proof and leak-proof containers. The known treatment method is cumbersome to operate, the workload is increased, and the chances of stab wounds and pollution are increased. Several common ways to collect discarded needles are: (1) Use sharps boxes: the price is high, and general medical units cannot afford it due to the large amount of use; (2) Use medical plastic packaging bags, the finished packaging bags are too thin to prevent Needle stick injury. In addition, when the disposable syringe leaves the factory, a needle cap is embedded on the nee...
