Description
Technical field
This utility model belongs to medical instruments field, is specifically related to a kind of disposable syringe.
Background technology
Disposable syringe is widely used in various medical treatment situations, and it mainly is made up of entry needle, overcoat, core bar and piston, piston bush be contained in the core bar top and with overcoat inner surface interference fit.Therefore when reality was used, the frictional resistance between piston and the core bar was bigger, so sliding is bad.Secondly when medical personnel when extracting medicinal liquid with this syringe because product self can make that once in a while piston comes off from core bar because frictional force is excessive, thereby have influence on medical worker's operation, waste medicinal liquid.
The utility model content
The purpose of this utility model is the deficiency that overcomes the existence of above-mentioned technology, and disposable syringe a kind of simple in structure, with low cost, that sliding capability is good is provided.
This utility model for realizing the technical scheme that above-mentioned purpose adopted is:
Disposable syringe, it comprises overcoat, core bar, entry needle, said overcoat top connects entry needle, suit core bar in the overcoat, the core bar top is with piston, it is characterized in that said core bar is provided with three retainer rings.
According to the described disposable syringe of this utility model, it is characterized in that said three retainer rings are respectively: top retainer ring, middle-end retainer ring and tail end retainer ring, and these three retainer ring diameters are all greater than the diameter of other part of core bar.
According to above-mentioned disposable syringe, it is characterized in that said top retainer ring is located at the tail end that is with the piston below and is close to piston, said middle-end retainer ring is located at the core bar middle-end, and the tail end retainer ring is provided with core bar handle top and is connected with handle.
This utility model adopted 3 fixed, guaranteed the original serviceability of syringe, have the following advantages simultaneously: 1, this product has been practiced thrift the core bar raw material in a large number, can increase competitiveness to enterprise; 2, this product is than the better use of conventional syringe; Since the whole operation process that core bar, makes injection than the light special patterns with it of traditional core bar than the conventional syringe labour-saving Duo 3, the core bar style of this product design better controls when medical personnel's clinical injection is operated.4, medical personnel can adopt the method for using same with conventional syringe, can not change the operation of medical workers custom.Therefore the utlity model has advantages such as simple in structure, easy to operate, that cost is low, sliding capability is good, have favorable economic benefit.
