Abstract

A disposable syringe without residual liquid medicine belongs to the medical appliance technical field and consists of a pin cylinder (1), a push rod (2), a piston (3) and a pin tube (4); the pin cylinder (1) is in movable and sealed connection with the piston (3); the front end of the piston (3) is matched with the inner wall of the front end of the pin cylinder (1); the back end of the piston (3) is connected with the push rod (2); the utility model is characterized in that a plurality of concave points are uniformly distributed on the outer wall of the pin cylinder (1); the pin tube (4) is fixed on the front end of the pin cylinder (1); the pin tube (4) is communicated with the inner cavity of the pin cylinder (1); the bottom of the pin tube (4) is level with the inner wall of the front end of the pin cylinder (1). The utility model has the advantages of simple structure and convenient operation; when a patient is injected, as the outer wall of the pin cylinder is provided with the concave points, the force can be well controlled to make the operation accurate; as the bottom of the pin tube is level with the inner wall of the front end of the pin cylinder, after injection is completed, no liquid medicine is remained in the pin cylinder and no waste of liquid medicine can be caused.

Description

The residual syringe of disposable no medicinal liquid

Technical field

This utility model belongs to technical field of medical instruments, the residual syringe of a kind of specifically disposable no medicinal liquid.

Background technology

The syringe that uses clinically mainly is made up of syringe needle, syringe, piston, push rod at present, and pinhead sleeve is contained on the syringe needle Connection Block of syringe front end, the syringe smooth in appearance, and finger is bad during use controls, exerts oneself, and makes operation inaccurate, the influence treatment; And in injection finishes the syringe needle Connection Block of back at the syringe front end, usually have medicinal liquid residual, cause liquid waste.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of and when injection syringe is controlled firmly easily, does not have the residual residual syringe of disposable no medicinal liquid of medicinal liquid in the syringe.

The purpose of this utility model is achieved in that the residual syringe of this disposable no medicinal liquid is made up of syringe, push rod, piston, needle tubing, slipper seal is connecting piston in the syringe, the front end of piston and syringe front inner wall adapt, the rear end is connected with push rod, on the syringe outer wall, be provided with a plurality of concave points uniformly, the syringe front end is being fixed needle tubing, and needle tubing communicates with the syringe inner chamber, and needle tubing is terminal concordant with the syringe front inner wall.

Advantage of the present utility model: simple in structure, easy to operate, when giving patient injection,,, make operation accurately so can be good at controlling firmly because the syringe outer wall is provided with concave point; And needle tubing is terminal concordant with the syringe front inner wall, and no medicinal liquid is residual in the syringe of back so injection finishes, and can not cause the waste of medicinal liquid.
