Abstract

The utility model relates to an automatic intravenous syringe, which belongs to the technical field of medical instruments. The automatic intravenous syringe comprises a needle head, a needle cylinder, a piston, a connecting rod, a sliding block, handles, a support spring, and a needle cylinder cover. The needle cylinder connected with the needle head at the front end is internally provided with the piston. The rear end of the piston is connected with the sliding block arranged inside the needle cylinder and adaptive to a cavity of the needle cylinder through the connecting rod. The handles on the side wall of the sliding block through axial through holes symmetrically with each other on the cylinder wall in the rear section of the needle cylinder are exposed out of the needle cylinder. A fixing strap is connected between external ends of the two handles. The needle cylinder cover provided with a slot on the external wall is in threaded connection at the rear end of the needle cylinder. The support spring is connected between the internal wall of the needle cylinder cover and the sliding block. The automatic intravenous syringe provided by the utility model has a simple structure and is simple and convenient to operate and saves time and labor when used to inject intravenously, thereby alleviating the work difficulty of nursing personnel.

Description

The vein automatic injector

Technical field

This utility model belongs to the medical instruments technical field, is a kind of vein automatic injector specifically.

Background technology

At present, the nursing staff often needs the tens minutes time to half an hour when carrying out intravenous injection to patient, and medical worker's both hands are held syringe during this period, and inject incessantly.This process operation trouble wastes time and energy, and has increased work difficulty to the nursing staff.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of vein automatic injector easy and simple to handle, time saving and energy saving when carrying out intravenous injection to patient is provided.

The technical scheme of this utility model is: this vein automatic injector is made up of syringe needle, syringe, piston, connecting rod, slide block, handle, support spring, syringe lid; The syringe inside that front end is connected with syringe needle is provided with piston; Piston rear end is through linking to each other with slide block that the syringe inner chamber adapts in connecting rod and the syringe; Be exposed at the syringe outside after two handles above the slider side wall pass axially extending bore symmetrical above the syringe back segment barrel respectively, be connected with fixing band between two handle outer ends; The back end of syringe outer wall that is being threaded is provided with the syringe lid of draw-in groove, is connected with support spring between syringe lid inwall and the slide block.

During use, the pulling handle is stuck in syringe to fixing band again after with injection suction syringe and covers in the draw-in groove of face, puncture and successfully then takes down fixing band from the syringe face of covering, and under the effect of support spring, can realize venous is injected automatically.

The beneficial effect of this utility model is: this utility model is simple in structure, and is easy and simple to handle, time saving and energy saving when carrying out intravenous injection to patient, alleviated nursing staff's work difficulty.
