Description
Technical field
This utility model relates to safety injector; be specifically related to a kind of safety injector with needle guard mechanisms, can prevent from especially that the employed syringe needles of medical apparatus and instruments such as syringe from meeting accident to stab medical care or cleanup crew's the safety injector with needle guard mechanisms after use.
Background technology
In medical practice, use very extensively with the medical apparatus and instruments of sharp-pointed syringe needle, such as syringe, hemostix etc.These medical apparatus and instruments are not only and are used by the professional in medical institutions and process, but also are usually used in the family by the layman and process.
The multiple disposable syringe major part of prior art outside syringe needle is exposed to, and is injected complete after taking packing apart, outside syringe needle is exposed to equally, be easy to stab the related personnel, cause very large difficulty for medical care or cleanup crew's collection and treatment, this stabbing also can cause bacteria infection.
In order to prevent the generation of accidental puncture, the syringe that syringe needle can be retracted after people had proposed to use.Although this syringe has solved the problem of easily stabbing medical personnel's hands, this syringe construction is complicated, and cost is high, malfunction.
Summary of the invention
The purpose of this utility model is: a kind of safety injector with needle guard mechanisms is provided, and simple structure, production cost is low, can prevent from that syringe with syringe needle from meeting accident to stab after use.
Technical solution of the present utility model is: this safety injector comprises syringe needle, syringe, helmet, push rod, plug and needle guard mechanisms, described syringe needle comprises needle stand and the pin that is installed on the needle stand, helmet is fixed on the syringe needle, syringe needle is fixed on the syringe with Rule outer cone locked joints, push rod with O type plug is installed in the hollow cavity of syringe, needle guard mechanisms is installed on the locked joints cylindrical of syringe, whole formation safety injector; Described needle guard mechanisms comprises the retaining collar that can be fixed together with syringe, the connecting portion that can combine with retaining collar, syringe needle can be received in inner protection arm, can stably needle guard mechanisms be positioned at retaining structure and the hinge member of various desired location.Described hinge member is connected between described connecting portion and the described protection arm, so that described protection arm can rotate with respect to described connecting portion; Described retaining structure has four pairs and holds button, and it comprises: packing holds button, use holds button and two pairs of symmetrical protections hold button.
Wherein, described packing holds button and comprises draw-in groove and helmet; described draw-in groove is formed on the U-shaped ribs of nearside of described protection arm; the radially inside and outside expansion in two pairs of upper end ends of U-shaped rib and form protuberance; when described protection arm with respect to described retaining collar turn to the angle of helmet hour; the protuberance of rib is crossed the outer peripheral face of helmet and helmet is fastened in the groove; prevent that protector from arbitrarily rotating in transportation; save packaging space; described a pair of retaining structure can be with the mode combination that can withdraw from, and described protector is in wrapping position.
Wherein, described packing holds button and uses front only the needs firmly just can will protect arm to release a little towards the direction away from helmet, and helmet withdraws from draw-in groove, so the protection arm begins to rotate until next position.
Wherein, described use holds button and comprises movable bottom grab and solid bottom claw; the nearside bottom of protection arm and the bottom of described connecting portion under it is respectively formed at; when described protection arm turns to the extreme position of the pin that deviates from syringe needle with respect to described connecting portion; described a pair of retaining structure can engage in the mode that can withdraw from, the use location when described protector is in injection or drawing liquid.
