Needle for medical clinical injector

Abstract

The invention discloses a needle for a medical clinical injector. The needle for the medical clinical injector comprises the injector and a clamping device, the injector is composed of a needle cylinder and an injection needle body, the needle cylinder is in a horizontally-placed cylindrical shape, the right side face of the needle cylinder is fixedly connected with a nipple, the left end of the surface of the needle cylinder is fixedly connected with a finger plate, a piston handle is slidably connected to the inner wall of the needle cylinder, the injection needle body is arranged on the right side face of the needle cylinder, and a piston is fixedly connected to the right side face of the piston handle. The needle is simple in structure and convenient to use, the problem of suction of liquid in a bottle is solved by arranging the injector, the front part of an inner-layer tube and the top end of a needle point are located on the same plane when liquid medicine is extracted, the liquid in the bottle can be effectively and completely sucked, waste is avoided, meanwhile, the suction efficiency is improved by arranging a telescopic rod and a first spring, the overall working efficiency is improved, and meanwhile, a sliding handle is arranged, so that the overall injection efficiency is improved, and recovery of a patient is facilitated.

Description

technical field [0001] The invention relates to the technical field of medical injectors, in particular to a needle used for medical clinical injectors. Background technique [0002] Syringes are a common medical tool. As early as the 15th century, Italian Catinel proposed the principle of syringes, which are mainly used for injecting liquid medicine or drawing liquid. Syringes can also be used for medical equipment, containers, such as some chromatography The scientific instruments in the instrument are injected through a rubber septum. Injecting gas into a blood vessel will cause an air embolism. The way to remove air from a syringe to avoid an embolism is to invert the syringe, tap it gently, and squeeze it out before injecting into the bloodstream A little liquid. [0003] At present, medical syringes are a kind of medical equipment commonly used in medical treatment. After diluting the liquid or extracting the liquid in the ampoule bottle, because of the needle point ...

AI Technical Summary

Problems solved by technology

[0003] At present, medical syringes are a kind of medical equipment commonly used in medical treatment. After diluting the liquid or extracting the liquid in the ampoule bottle, because of the needle point at the needle, the liquid in the bottle is often not drawn cleanly, resulting in a certain waste. At the same time, because most of the liquid medicine is antibiotics, etc., the processing cost is increased during processing. Improper handling will also cause a certain impact on the environment. For this reason, we propose a needle used for medical clinical syringes.
