Abstract
The utility model relates to a safe syringe needle. A needle tube of a syringe needle is sheathed with a sleeve tube which can slide along the needle tube, the sleeve tube is connected with an elastic cambered metal wire and the other end of the cambered metal wire is connected to the tail part of the needle. At ordinary time, the sleeve tube is sheathed at the needle tip part, and accordingly, the sleeve tube covers a needle tip. During injection, the sleeve tube is blocked, only the needle tube is punctured into a punctured body. After the needle tube is drawn, the needle tube is pushed back caused by bearing the outward elastic force of the elastic cambered metal wire to cover the needle tip, and thus, the aim for preventing accidental hurt by puncturing is achieved.
Description
Affiliated technical field
This utility model relates to a kind of medication injections utensil.
Background technology
At present, injection needle commonly used all exposes, and is stabbed carelessly in the use and causes transmission of disease easily.
Summary of the invention
In use stabbed the deficiency that causes pathophoresis easily in order to overcome injection needle commonly used carelessly because of exposure causes, this utility model provides a kind of syringe needle, can effectively address this problem.
The technical scheme that its technical problem that solves this utility model adopts is: on the needle tubing of injection needle, overlapping one can be along the sleeve pipe of needle tubing slip, be connected with the flexible arc tinsel on the sleeve pipe, the curved metal silk other end is connected in the afterbody of syringe needle, usually marquis the time, casing pipe sleeve is at the needle point position, thereby needle point is hidden.During injection, sleeve pipe is blocked and has only needle tubing to penetrate and pricked in the body, extract needle tubing out after, sleeve pipe is pushed back the needle point covering because of being subjected to the outside elastic force of flexible arc tinsel, reaches to prevent the purpose of being stabbed carelessly.
The beneficial effects of the utility model are, can prevent to be stabbed by syringe needle carelessly not influencing under the normally convenient situation about using of injection needle.
Description of drawings
Below in conjunction with accompanying drawing this utility model is further specified.
Fig. 1 is a vertical section of the present utility model structural map.
Fig. 2 is the structure chart of elasticity curved metal silk (4) when not welding in this utility model.
1. sleeve pipes among the figure, 2. sleeve pipe concave inward structure, 3. the flexible arc tinsel stops end, 4. flexible arc tinsel, 5. backshank, 6. needle tubing, 7. injection needle
The specific embodiment
The backshank (5) of Fig. 1 middle sleeve (1) and injection needle (7) is symmetrically welded by two flexible arc tinsels (4) and links to each other.The flexible arc tinsel stops that end (3) is hook-shaped.
Usually marquis the time, sleeve pipe (1) is enclosed within the needle point position, during injection, sleeve pipe (1) is pricked body and is stopped, have only needle tubing (6) to penetrate and pricked in the body, extract needle tubing (6) out after, sleeve pipe (1) is pushed back needle point is hidden because of being subjected to the outside elastic force of flexible arc tinsel (4).The sleeve pipe concave inward structure (2) of sleeve pipe (1) front end can make at when injection sleeve pipe (1) and be difficult for being stained with liquid such as blood, body fluid.
When drawing liquid medicine from liquid medicine bottle, the flexible arc tinsel stops that end (3) is against on the bottle mouth wall of liquid medicine bottle, thereby sleeve pipe (1) is blocked, and needle tubing (6) can stretch into and draw liquid medicine in the liquid medicine bottle.The flexible arc tinsel stops that end (3) is on the hook-shaped bottle mouth wall that can make it be against liquid medicine bottle and is difficult for slippage.
Claims (1)
- A kind of safety needle, form by sleeve pipe (1), flexible arc tinsel (4), injection needle (7), it is characterized in that: the backshank (5) of sleeve pipe (1) and injection needle (7) is symmetrically welded by two flexible arc tinsels (4) and links to each other, and the flexible arc tinsel stops that end (3) is hook-shaped; Sleeve pipe can slide along needle tubing.
