Description
Technical field
This utility model relates to a kind of medical needle set, is specifically related to a kind of Anti-stabbing scalp acupuncture.
Background technology
Pricking wound a kind ofly enters skin deep part by syringe needle and be enough to the unexpected injury that makes victim hemorrhage.As contaminated syringe needle, sharp instrument injury then have the danger infecting Emperical Bayesian method.Existing disposable scalp acupuncture is made up of syringe needle, the pin wing, nylon leather hose, the pin wing is fixed on the front portion of nylon leather hose, syringe needle is fixed on the front end of nylon leather hose, and also always exposedly not protect outside after using, its major defect is: scalp acupuncture syringe needle is in free exposed state or puts into sharp disposable container process again in separation after extracting in patient body, easily causes pricking wound.Much research shows, nurse is the professional colony that in hospital, pricking wound occurrence frequency is the highest, and incidence rate is 88.97%, and nurse is also the colony occurred frequently infecting Emperical Bayesian method simultaneously.More than 20 can be propagated by pricking wound and plant hematogenous infectious disease, wherein the most common, to endanger maximum be HBV, HCV, HIV.When nursing staff's accidental needle sticks wound almost all occurs in and pulls out liquid, trace it to its cause and mainly contain: 1. tradition is separated after pin is pulled out in scalp needle for infusion operation and gets fluid bag immediately, scalp acupuncture is in free state, easily stab the people of oneself and periphery, and when processing the syringe needle pricking bottle stopper, likely cause the secondary pollution of blood.2. all pending article of tradition separation scalp needle for infusion operation are put together, easily stab, although the injuries such as medical worker is stabbed by sharp instrument in curative activity, scratch are still inevitably.
Summary of the invention
For the deficiency that prior art exists, the purpose of this utility model is that providing a kind of uses safer Anti-stabbing scalp acupuncture.
For achieving the above object, this utility model provides following technical scheme: a kind of Anti-stabbing scalp acupuncture, comprise syringe needle, tube for transfusion, it is characterized in that: be also provided with safety shield, described syringe needle is fixed on the end of tube for transfusion, described safety shield is tubular element, described syringe needle and tube for transfusion are axially slidably disposed in safety shield, length and the described needle length of described safety shield match, described syringe needle has the working position that a syringe needle exposes and the recovery position be in completely in safety shield in safety shield, the end tube wall of described tube for transfusion is provided with the retaining sheet of one end tilting, the inwall of described safety shield rear and front end is respectively equipped with the first draw-in groove matched with retaining sheet and the second draw-in groove, described safety shield outer wall and the first draw-in groove opposite position are provided with pressing piece, working position is with under the state of recovery position, described retaining sheet position is corresponding with the first draw-in groove and the second draw-in groove respectively.This utility model Anti-stabbing scalp acupuncture is owing to being axially slidably disposed in a safety shield by syringe needle and tube for transfusion, and the end tube wall of tube for transfusion is provided with the retaining sheet that one end tilts, the inwall of safety shield rear and front end and working position and reclaim on position that position matches and be respectively equipped with the first draw-in groove and the second draw-in groove that match with retaining sheet, like this, when scalp acupuncture is in the process punctured and infuse, retaining sheet is stuck in the first draw-in groove and is in working position, after completing transfusion operation, retaining sheet is pressed by pressing pressing piece, pull back tube for transfusion to retaining sheet to be stuck in the second draw-in groove to be in and to reclaim position state simultaneously, syringe needle is retracted in safety shield completely, thus avoid surprisingly causing accidental injury to medical worker.
This utility model is arranged further: described safety shield inwall is provided with connection first draw-in groove and the second draw-in groove gathering sill, and described gathering sill cross section and retaining sheet cross section match.By arranging gathering sill, conveniently pull back syringe needle time retaining sheet energy auto-alignment snap in the second draw-in groove.
This utility model is arranged further again: corresponding first slot of described safety shield installs the arch guard shield that flexible material makes and forms described pressing piece.Be provided with arch guard shield and form described pressing piece, structure is simple and retaining sheet can be prevented damaged.
Below in conjunction with the drawings and specific embodiments, this utility model is further described.
