Problems solved by technology

[0002] According to the traditional anesthetic injection syringe, although the material of the injection syringe is very good in design, it is designed to be used with the special stainless steel syringe in the current medical equipment, and the stainless steel syringe is due to the cost. It is expensive and cannot be discarded after use, so it usually needs to be disinfected and reused after use. Once the disinfection is not complete, it will cause the risk of bacterial infection
Also, the needle at the front end of the anesthetic injection syringe is a double-ended needle. Usually, after use, the double-ended needle needs to be removed from the front end of the stainless steel syringe and then the stainless steel syringe is sterilized. It is easy to puncture the fingers of medical staff, which will also cause the risk of bacterial infection

Abstract

A disposable high-safety injector for anesthetic is composed of main tube, push rod, needle and protecting sleeve. It features that its all parts are made of plastics and after it is used; its needle can be withdrawn into its protecting sleeve and fastened in it, so it can not be used again.

Description

technical field [0001] The invention relates to a disposable anesthetic safety injection syringe, in particular to a disposable safety injection syringe with a safety protection sleeve belonging to the technical field of medical equipment. Background technique [0002] According to the traditional anesthetic injection syringe, although the material of the injection syringe is very good in design, it is designed to be used with the special stainless steel syringe in the current medical equipment, and the stainless steel syringe is due to the cost. It is expensive and cannot be discarded after use, so it usually needs to be disinfected and reused after use. Once the disinfection is not complete, it will cause the risk of bacterial infection. Also, the needle at the front end of the anesthetic injection syringe is a double-ended needle. Usually, after use, the double-ended needle needs to be removed from the front end of the stainless steel syringe and then the stainless steel ...
