Abstract
The utility model provides a medical injection needle head, and belongs to the technical field of medical appliances. The medical injection needle head comprises a needle handle (2) and a needle body (1), and is characterized in that the needle handle (1) is sleeved and fixed in the central hole at the bottom of a round sleeve (3); two symmetric annular bulges (4) are alternately formed on the outer wall of the sleeve (3); and an elastic rubber ring (5) with inner diameter less than outer diameter of the needle tube is connected and fixed on the inner wall of the opening end of the sleeve. The medical injection needle head is simple in structure, and can prevent the needle body from being polluted when the injection needle head is arranged on the needle tube to avoid cross infection, and the needle head and the needle tube are firmly fixed, so that the working difficulty of medical staff can be alleviated.
Description
Technical field: this utility model belongs to the medical instruments technical field, is a kind of syringe needle specifically.
Background technology: at present, employed injection needle mainly is made of needle handle and needle body clinically, because the volume of needle handle is smaller, is being easy to pollute needle body when needle tubing is installed, thereby is causing cross infection; And injection needle is fixing also insecure on needle tubing, has increased medical worker's work difficulty.
Summary of the invention: the purpose of this utility model is to overcome above-mentioned deficiency, and provide a kind of and when needle tubing is installed injection needle, can prevent that needle body from being polluted, and the syringe needle of syringe needle and needle tubing fixation.
The technical solution of the utility model is: this syringe needle comprises needle handle and needle body, it is characterized in that needle handle suit is fixed at the bottom of the circular sleeve cylinder in the centre bore, sleeve outer wall is interval with two symmetrical annular protrusions, and the opening end inwall is being connected and fixed internal diameter less than the elastic rubber ring of needle tubing external diameter.
When toward needle tubing injection needle being installed, sleeve set get final product at needle tubing front end and nipple that needle handle is installed in above the needle tubing, the interior elastic rubber ring of sleeve can firmly be fixed on sleeve on the needle tubing.
The beneficial effects of the utility model are: this utility model is simple in structure, can prevent that needle body from being polluted when needle tubing is installed injection needle, avoids causing cross infection, and syringe needle and needle tubing fixation, has alleviated medical worker's work difficulty.
Description of drawings: accompanying drawing 1 is structure cutaway view of the present utility model.
The specific embodiment: be described in further detail below in conjunction with 1 pair of this utility model of accompanying drawing: this syringe needle comprises needle handle 1 and needle body 2, it is characterized in that needle handle 1 suit is fixed at the bottom of 3 of the circular sleeves in the centre bore, sleeve 3 outer walls are interval with two symmetrical annular protrusions 4, and the opening end inwall is being connected and fixed internal diameter less than the elastic rubber ring 5 of needle tubing external diameter.
