Abstract
The utility model relates to the technical field of medical machinery and particularly relates to an injector, comprising a syringe and a push rod, wherein the push rod is arranged inside the syringe and can stretch out from the back end of the syringe; a convex plate is vertically arranged at the back end of the syringe; the injector is characterized in that: an annular bulge is arranged at the front part of the syringe along an external circle; two arc-shaped bumps are symmetrically arranged on the outer circle of the middle part of the syringe; the edge of the convex plate which is arranged at the back end of the syringe is squared and an anti-sliding bump is distributed on the back end face of the push rod; and the anti-sliding bump is in a semispherical shape. The injector disclosed by the utility model has the characteristics of simple and reasonable structure, convenience for operation and capability of improving the working efficiency.
Description
Technical field
This utility model relates to a kind of technical field of medical instruments, specifically a kind of syringe.
Background technology
Syringe often and hypodermic needle connect together and be used for medicinal liquid is injected in the body.Syringe is divided into two kinds of plastic and glasses according to material, and goes out the scale indication of liquid volume at the syringe subscript.Glass syringe is reusable after with autoclave sterilization, and the plastic injector cost is lower, processes disposable product usually; Above-mentioned two kinds of syringes in use because the syringe outer wall is smooth, clamping difficulty during injection; Cause finger to slide easily, the accuracy of influence operation.
Summary of the invention
This utility model provides a kind of simple and reasonable for structure, easy to operate, the syringe of increasing work efficiency in order to overcome above-mentioned defective.
The technical scheme that this utility model adopts is: a kind of syringe, comprise syringe, push rod, and push rod is arranged on syringe inside and can stretches out from back end of syringe; Back end of syringe vertically is provided with flange; It is characterized in that: along cylindrical annular protrusion is set in the syringe front portion, on the cylindrical of syringe middle part, is symmetrical set two arc bumps, the edge of the flange of back end of syringe is square; Distributed and arranged has anti-skidding projection on the rear end face of said push rod, and this anti-skidding projection is hemispherical
.
This utility model is provided with symmetric two arc bumps at the middle part simultaneously owing to be provided with annular protrusion in the syringe exterior front, can increase the frictional resistance of syringe, clamping when being convenient to inject; The rear end face of push rod is provided with anti-skidding projection, also is in order to increase frictional resistance, to be convenient to injection operation; It is more convenient to make dispensing operation or in syringe, suck liquid; It is square structure that the flange of back end of syringe is arranged to the edge, and syringe is difficult for rolling when placing like this, places stable.
Description of drawings
Fig. 1 is the sketch map of this utility model.
The specific embodiment
Combine accompanying drawing that this utility model is further described, Fig. 1 is a kind of embodiment of this utility model at present, comprises syringe 1, push rod 2, and push rod 2 is arranged on syringe 1 inside and can stretches out from syringe 1 rear end, and syringe 1 rear end vertically is provided with flange 3.This utility model is provided with annular protrusion 4 in syringe 1 front portion along cylindrical; Usually annular protrusion 4 is provided with three to five; On syringe 1 middle part cylindrical, also be symmetrical set two arc bumps 5; The edge of the flange 3 of syringe 1 rear end is square, and distributed and arranged has anti-skidding projection 6 on the rear end face of said push rod 2, and this anti-skidding projection 6 is hemispherical
.
This utility model is provided with annular protrusion 4 in syringe 1 exterior front, and is provided with symmetric two arc bumps 5 at the middle part, all is in order to increase the frictional resistance of held syringe 1, and clamping when being convenient to inject makes things convenient for injection operation.The rear end face of push rod 2 is provided with anti-skidding projection 6, also is in order to increase frictional resistance, to be convenient to injection operation, thereby improves medical personnel's work efficiency.It is square structure that the flange 3 of syringe 1 rear end is arranged to the edge, and syringe is difficult for rolling when placing like this, places stable.
The utlity model has simple and reasonable for structure, easy to operate, the characteristics of increasing work efficiency.
