Description
Technical field
This utility model relates to a kind of entry needle, refers in particular to a kind of anti-accidental injury pumping needle head unit.
Background technology
Traditional pumping needle uses back needle point unprotect device, and the hands of accidentally injuring doctor or nurse easily refers to; Simultaneously, when reclaiming medical waste, the staff is also accidentally injured easily; This situation is concerning the syringe needle that is used for noninfectious treatment and uses, and to the doctor, protect personnel etc. and do not have too much influence, but to being used for the syringe needle after the infectious disease treatment, as hepatitis, AIDS disease etc., consequence is just very serious.
Summary of the invention
The purpose of this utility model be to provide a kind of safe, can prevent a kind of anti-accidental injury pumping needle head unit of accidentally injuring.
The purpose of this utility model is achieved in that a kind of anti-accidental injury pumping needle head unit, comprises needle body, is arranged on the needle stand at needle body rear portion, and wherein: the forward needle body outer race of described needle stand is provided with sliding sleeve, is provided with spring between needle stand and sliding sleeve; Spring housing is located at outside the needle body, fixedlys connected with sliding sleeve with needle stand respectively in its two ends; Between sliding sleeve and needle stand, be provided with snapping and relieving mechanism, just be socketed in the needle body front end when sliding over the spring elongation.
Snapping described in the above-mentioned anti-accidental injury pumping needle head unit and relieving mechanism can be provided with hiding hole in the forward needle body of needle stand periphery, fixedly connected with the bottom in hiding hole in the lower end of spring; Side walls hinged in hiding hole have a button, and the button inboard is provided with flange, is being provided with breach with the corresponding sliding sleeve outer wall of flange, and sliding sleeve is positioned at when hiding the hole, flange and breach snapping.
Snapping described in the above-mentioned anti-accidental injury pumping needle head unit and relieving mechanism also can be provided with circumferential catching groove and at least one axial slide in the needle stand appearance, and chute and catching groove are communicated with, the button that adapts at the setting of sliding sleeve lower end and catching groove and chute.Can realize snapping equally and discharge sliding sleeve, and be communicated with catching groove for good, be provided with symmetric two buttons in the sliding sleeve lower end to be provided with symmetric two chutes in the needle stand appearance.
After this utility model adopts said structure, when normally using needle injection, sliding sleeve is snapped onto the needle stand front portion, after syringe needle is used to complete, can or rotate sliding sleeve by pressing button, the elastic force effect that slides over spring be discharged down move to the needle body front end, needle point is hidden, prevent that medical personnel from being accidentally injured by syringe needle, avoid infected chance.
