Abstract

The utility model belongs to the field of medical instruments and particularly relates to a connecting structure of a syringe piston and an antiskid ring cylindrical core rod. The technical scheme includes that the connecting structure is characterized in that a fixed core rod head is processed at the front end of the stepped antiskid cylindrical core rod, a piston is mounted on the fixed core rod head, and a core rod push handle and a button are processed at the tail end of the stepped antiskid cylindrical core rod. In conclusion, a fixing ring is processed on the fixed core rod head (3), so that stability and reliability in working of the piston (2) can be guaranteed.

Description

The syndeton of a kind of syringe piston and anti-slip ring cartridge type core bar

Technical field

This utility model belongs to the medical apparatus field, specifically relates to the syndeton of a kind of syringe piston and anti-slip ring cartridge type core bar.

Background technology

The core bar of the present syringe that uses clinically, ubiquity the raw-material structural design of waste, because the syringe of Shi Yonging is disposable clinically, so waste suitable surprising, medical personnel are when inhaling medicine and injection operation, the syringe core rod push-and-pull is effort relatively also, and hands is easily from the landing of overcoat edge, thereby causes the generation of malpractice.

The utility model content

The purpose of this utility model just is to overcome above-mentioned shortcoming, and the syndeton of a kind of syringe piston that provides and anti-slip ring cartridge type core bar.

This utility model is achieved in that the syndeton of a kind of syringe piston and anti-slip ring cartridge type core bar, it is characterized in that: the front end at the anti-skidding cartridge type core bar of ladder is processed with fixedly pin head, piston fixedly is being installed above the pin head, is being processed with core bar at the end of the anti-skidding cartridge type core bar of ladder and pushes away handle and button.

Description of drawings

The utility model is described in more detail below in conjunction with accompanying drawing.

Each label declaration is as follows among the figure:

1, syringe, 2, piston, 3, fixing pin head, 4, the anti-skidding cartridge type core bar of ladder, 5, the syringe flange, 6, core bar pushes away handle, 7, button.

The specific embodiment

Syringe 1 of the present utility model is selected the time processing molding in mould of PP polypropylene material for use, the effect of syringe 1 is to store medicinal liquid and piston 2 is slided in syringe 1, piston 2 is selected the time processing molding in mould of butyl rubber material for use, the effect of piston 2 is exactly the thrust that pushes away handle 7 by core bar, the medicinal liquid that stores in the syringe 1 is passed through syringe needle, in patient's body, inject, perhaps the medicinal liquid that stores in the syringe 1 is carried out other operation etc. by syringe needle, fixedly pin head 3 is selected the time processing molding in mould of PP polypropylene material for use, fixedly be processed with retainer ring above the pin head 3, its effect is exactly fixed piston 2, the anti-skidding cartridge type core bar 4 of ladder is selected the time processing molding in mould of PP polypropylene material for use, its effect is exactly to guarantee that fixedly piston 2 working stabilities above the pin head 3 are reliable, on the anti-skidding cartridge type core bar 4 of ladder, be processed with syringe flange 5, syringe flange 5 is selected the time processing molding in mould of PP polypropylene material for use, its effect is exactly easy to operate reliable and stable when injecting, core bar pushes away handle 6 and selects the time processing molding in mould of PP polypropylene material for use, its effect is exactly when working, guarantee that anti-skidding cartridge type core bar 4 working stabilities of ladder are reliable, button 7 on pushing away handle 6, core bar is installed, button 7 is selected the time processing molding in mould of PP polypropylene material for use, its effect be exactly when working stable operation reliable.

In sum, this utility model can guarantee that like this piston 2 working stabilities are reliable owing to fixedly be processed with retainer ring above the pin head 3.

Claims

1. the syndeton of a syringe piston and anti-slip ring cartridge type core bar, it is characterized in that: the front end at the anti-skidding cartridge type core bar of ladder is processed with fixedly pin head, piston fixedly is being installed above the pin head, is being processed with core bar at the end of the anti-skidding cartridge type core bar of ladder and pushes away handle and button.
