Abstract
The invention relates to a safety type disposable scalp needle. The safety type disposable scalp needle comprises a syringe needle and an infusion tube, wherein the syringe needle is fixed at the end part of the infusion tube; a needle wing is arranged on the side face of the end part of the the infusion tube ; the safety type disposable scalp needle is further provided with a safety protective jacket; one circle of convex clamping ring is arranged on the outer wall of the end part of the infusion tube. According to the safety type disposable scalp needle, the syringe needle and the infusion tube are slidably arranged in one safety protective jacket, so that the front part of the safety protective jacket is in clearance fit with the clamping ring and the rear part of the safety protective jacket is in interference fit with the clamping ring. When the disposable scalp needle is used up, the infusion tube is backwards pulled until the clamping ring is in interference fit with the pipe wall of the back part of the safety protective jacket, so that the infusion tube is clamped and the syringe needle is completely retracted into the safety protective jacket, and furthermore, accidental injuries to medical personnel are avoided.
Description
Technical field
The present invention relates to a kind of medical needle set, be specifically related to the disposable scalp acupuncture of a kind of safety.
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 object of the present invention is to provide the disposable scalp acupuncture of safety that a kind of use is safer.
For achieving the above object, the invention provides following technical scheme: the disposable scalp acupuncture of a kind of safety, comprise syringe needle, tube for transfusion, described syringe needle is fixed on the end of tube for transfusion, the end sides of described tube for transfusion is provided with the pin wing, it is characterized in that: be also provided with safety shield, the end outer wall of described tube for transfusion is provided with the snap ring of a circle projection, described safety shield is tubular element, before and after described safety shield, internal diameter differs, forward part and described snap ring matched in clearance, rear section and described snap ring interference fit, described safety shield is axially set in outside syringe needle and tube for transfusion slidably, length and the described needle length of described safety shield match, described safety shield tube wall is provided with one end and is provided with the grooving that width coordinates with pin wing thickness gap vertically, the open end of described grooving in leading section namely towards syringe needle side.
The disposable scalp acupuncture of safety of the present invention 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 protruding snap ring, safety shield forward part and described snap ring matched in clearance, rear section and described snap ring interference fit.When disposable scalp acupuncture is finished using, pull back tube for transfusion and block tube for transfusion to snap ring and safety shield rear portion tube wall interference fit, syringe needle is retracted in safety shield completely, thus avoids surprisingly causing accidental injury to medical worker, and structure is very simple.
Below in conjunction with the drawings and specific embodiments, the invention will be further described.

Detailed description of the invention
As shown in Figure 1, the disposable scalp acupuncture of safety comprises syringe needle 1, tube for transfusion 2 and safety shield 3, described syringe needle 1 is fixed on the end of tube for transfusion 2, the side, end (or both sides) of described tube for transfusion 2 is provided with the pin wing 4 of handled easily, and the end outer wall of described tube for transfusion 2 is provided with the snap ring 5 of a circle projection.As illustrated in figs. 5-7, described safety shield 3 is tubular element, before and after described safety shield 3, internal diameter differs, forward part and described snap ring 5 matched in clearance, rear section and described snap ring 5 interference fit, as shown in Figure 7, before and after described safety shield 3, internal diameter can be that taper is arranged, in this specific embodiment, as shown in Figure 6, before and after the endoporus of described safety shield 3, two sections of internal diameters differ setting, cone connection is provided with between described two sections, the leading portion internal diameter of described safety shield 3 coordinates with described snap ring 5 crest clearance, the back segment internal diameter of described safety shield 3 coordinates with described tube for transfusion 2 crest clearance, with described snap ring 5 interference fit in the middle of cone connection, as Fig. 3, shown in 4.Described safety shield 3 is axially set in outside syringe needle 1 and tube for transfusion 2 slidably, described safety shield 3 tube wall is provided with one end and is provided with the grooving 6 that width coordinates with the pin wing 4 thickness gap vertically, the open end of described grooving 6 in leading section namely towards syringe needle 1 side.Length and described syringe needle 1 length of described safety shield 3 and grooving 6 will match, namely enough displacements should be had to make described snap ring 5 slide to cone connection interference fit with it when the described pin wing 4 is sliding after grooving 6, when described snap ring 5 slides to cone connection and cone connection interference fit, described safety shield 3 should have sufficient length to be accommodated in safety shield 3 by whole syringe needle 1, as in Figure 2-4, thus avoid surprisingly causing accidental injury to medical worker, the preferred employing of described snap ring 5 has certain elastic material such as silica gel and makes, more be conducive to and cone connection interference fit.
