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

The present invention is a disposable anesthetic safety injection syringe, which mainly discloses an injection syringe consisting of a syringe, a push rod, a needle and a safety protection sleeve. The feature of the present invention is that all components of the injection syringe are made of plastic After use, the needle is retracted into the safety protection sleeve and locked, and all the components of the syringe can be discarded without repeated disinfection, so as to prevent infection due to accidental disinfection.

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 in 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 syringe is...
