CN203227153U - Syringe with inner stopper - Google Patents

Abstract

The utility model belongs to the field of medical instruments and particularly relates to a syringe with an inner stopper. The technical scheme includes that the syringe is characterized in that a solid push rod is mounted in a sleeve, a fixing ring is processed at the front end of the solid push rod, the inner stopper is mounted on the fixing ring, a piston is mounted on the inner stopper, and a guide sleeve is mounted at the tail end of the solid push rod. In conclusion, the guide sleeve (6) is mounted on the sleeve (1), and the cross section of the solid push rod (5) is processed to be quite small, so that raw materials can be greatly saved; the inner stopper (3) is mounted on the fixing ring, so that stability and reliability in working of the piston (2) in the sleeve (1) can be guaranteed.

Description

A kind of syringe that has internal congestion

Technical field

This utility model belongs to the medical apparatus field, specifically relates to a kind of syringe that has internal congestion.

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 a kind of syringe that has internal congestion that provides.

This utility model is achieved in that a kind of syringe that has internal congestion, it is characterized in that: in the inside of sleeve solid push rod is installed, front end at solid push rod is processed with retainer ring, internal congestion is installed on retainer ring, piston is installed on internal congestion, at the end of solid push rod fairlead is installed.

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, sleeve, 2, piston, 3, internal congestion, 4, retainer ring, 5, solid push rod, 6, fairlead, 7, pusher grip.

The specific embodiment

Sleeve 1 of the present utility model is selected the time processing molding in mould of PP polypropylene material for use, the effect of sleeve 1 is to store medicinal liquid and piston 2 is slided in sleeve 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 by solid push rod 5, the medicinal liquid that stores in the sleeve 1 is passed through syringe needle, in patient's body, inject, perhaps the medicinal liquid that stores in the sleeve 1 is carried out other operation etc. by syringe needle, internal congestion 3 is selected the time processing molding in mould of PP polypropylene material for use, its effect is exactly fixed piston 2, guarantee that piston 2 working stabilities are reliable, retainer ring 4 is selected the time processing molding in mould of PP polypropylene material for use, its effect is exactly to guarantee that piston 2 working stabilities above the pin head 3 are reliable, solid push rod 5 is selected the time processing molding in mould of PP polypropylene material for use, its effect is exactly to guarantee that retainer ring working stability in sleeve 1 is reliable, fairlead 6 is selected the time processing molding in mould of PP polypropylene material for use, it is easy to operate reliable and stable when its effect is exactly 5 injections of solid push rod, core bar pushes away handle 7 and selects the time processing molding in mould of PP polypropylene material for use, its effect is exactly when working, and guarantees that piston 2 working stabilities are reliable.

In sum, this utility model is owing to be equipped with fairlead 6 on sleeve 1, the cross section of solid like this push rod 5 is processed into very little, can save raw material greatly like this, owing at retainer ring internal congestion 3 is installed, can guarantees that the working stability of piston 2 in sleeve 1 is reliable simultaneously.

Claims (1)

1. syringe that has internal congestion, it is characterized in that: in the inside of sleeve solid push rod is installed, is processed with retainer ring at the front end of solid push rod, internal congestion is installed on retainer ring, piston is installed on internal congestion, at the end of solid push rod fairlead is installed.
