Abstract
The utility model discloses an integrated drug and needle injector. The utility model comprises a pinhead, a syringe, a piston, a handspike and a bayonet cap, wherein the pinhead and the bayonet cap are integrated; The rear end of the syringe is provided with a piston that can slide within the syringe; the central piston along the axial direction is arranged with an piston central hole with inner worms; the surrounding edge of the joint between the pinhead and the syringe has a slide proof protuberance; the internal surrounding edge of the opening end of the bayonet cap is provided with a socket matched with the slide proof protuberance. Due to adopting the above structure, the liquid medicine directly stores in the syringe so as to being without the trouble that ordinary syringe firstly needs to inject the liquid medicine into the tube. When being used, the injector is pulled out the bayonet cap and the front end of the handspike is revolved into the piston central worm hole, and then the utility model can be used for injecting.
Description
Technical field
This utility model relates to a kind of injector for medical purpose, relates in particular to the syringe of the direct use of disposable medicine pin one.
Background technology
At present, generally the syringe of Shi Yonging all is that medicinal liquid and syringe are isolating, will extract medicinal liquid from liquid storage peace bottle with entry needle during use, the peace bottle of sealing needs to fracture from bottleneck earlier to extract medicinal liquid, not only medical worker's troublesome poeration but also pollute easily.Chinese patent discloses a kind of " disposable injection peace bottle ", though this disposable injection peace bottle has solved ordinary syringe and has wanted to extract medicinal liquid earlier from the peace bottle, the problem of injecting again, be that medicinal liquid directly is stored in the syringe, but because syringe and syringe needle are isolating, during use syringe needle to be installed now, often cause the sealing of syringe needle and injection tube bad, and syringe separate and also is not easy to deposit with syringe needle.
Summary of the invention
The purpose of this utility model is exactly the problem that exists at above disposable injection peace bottle, and a kind of improved syringe is provided, and has advantage simple in structure, esy to use, safe and reliable.
The purpose of this utility model is to realize like this, this syringe comprises syringe needle, syringe, piston, push rod, the pin medicated cap, described syringe needle and pin medicated cap are structure as a whole, there is a piston that can slide the rear end of described syringe in syringe, described piston center is provided with the piston center hole of a female thread vertically, there is an on-slip projection described syringe needle and border, syringe junction, the inboard border of described pin medicated cap opening is provided with the groove that matches with the on-slip projection, so that being buckled on the syringe needle that the pin medicated cap is firm do not slipped down, the front end of described shank be provided with piston center hole on the external screw thread that matches of female thread so that push rod and piston are fixed.
Because adopt said structure, medicinal liquid directly is stored in the syringe, has saved ordinary syringe and wanted earlier the trouble in the medicinal liquid suction tube.During use, pull out the pin medicated cap, the front end of push rod being screwed in the screwed hole of centre of piston is injectable.
Description of drawings
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing
