Abstract
The utility model provides a rotating syringe, includes syringe needle, cylinder and spiral piston, the syringe needle is connected on the cylinder, and the spiral piston sets up in the cylinder, the spiral piston includes hob, spiral handle and sealing, sealing, other end connection spiral handle are connected to the one end of hob, the hob is through setting up the spiral bayonet socket and cylinder swing joint in cylinder one end. The utility model discloses a rotating syringe releases the medicine through the rotatory spiral handle of handle when using, when rotatory easy control accuracy, simultaneously can be very steady release the medicine. Simultaneously, the syringe needle adopts the spiral installation of screwing, can prevent that the syringe needle from droing, causes the extravagant and environmental pollution of liquid medicine, is particularly suitable for the vein and injects the liquid medicine use.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly relates to a kind of rotating syringe.
Background technology
Existing syringe is all flat push type syringe mostly, because when operating, the bad control of dynamics causes the precision of injecting fluid medicine not high, simultaneously because medicine is extruded by promoting piston by hand propelled, too fast, makes patient uncomfortable, crosses and then affect efficiency slowly.
Utility model content
The technical problems to be solved in the utility model overcomes the deficiencies in the prior art, provide a kind of injection precision high, inject stable rotating syringe.
For solving the problems of the technologies described above, the technical scheme that the utility model proposes is: a kind of rotating syringe, comprises syringe needle, syringe and screw piston; Described syringe needle is connected on syringe, and described screw piston is arranged in syringe; Described screw piston comprises screw rod, spiral handle and sealing; One end of described screw rod connects sealing, the other end connects spiral handle; Described screw rod is flexibly connected with syringe by the spiral bayonet socket being arranged on syringe one end.Medicine in use, is released by rotatable handle spiral handle by rotating syringe of the present utility model, and easily medicine can be released by control accuracy, while very stably when rotated.
Above-mentioned rotating syringe, preferably, the connecting portion that described sealing comprises sealing ring and wrapped up by sealing ring, described connecting portion is connected with screw rod.
Above-mentioned rotating syringe, preferably, described syringe needle comprises pin stalk, pintle, flexible pipe and union joint; Described pin stalk is connected on pintle, and one end of described flexible pipe connects pintle, the other end connects union joint; Described union joint is connected on the nipple of syringe.
Above-mentioned rotating syringe, preferably, described nipple is provided with external screw thread, described union joint is provided with female thread, and described union joint is fixedly connected with nipple with external screw thread by female thread.Adopt and spirally screw installation, prevent disposable syringe from often causing syringe needle to come off from needle handle because pressure is excessive when administration, injection pressurization.
Compared with prior art, the utility model has the advantage of: medicine in use, is released by rotatable handle spiral handle by rotating syringe of the present utility model, easily medicine can be released by control accuracy, while very stably when rotated.Meanwhile, syringe needle employing is spiral screws installation, can prevent syringe needle from coming off, cause liquid waste and environmental pollution, is particularly suitable for intravenous injection medicinal liquid and uses.
