Abstract

The invention relates to a hydrogen peroxide injecting device of a rotating disc type low-temperature plasma sterilizer. A fixed elastic clip is adopted, and a hydrogen peroxide capsule is filled in the elastic clip. One stepping motor is utilized to drive the elastic clip to rotate for 360 degrees and move and position the capsule in the elastic clip, and another stepping motor is utilized to drive a syringe needle to cause the syringe needle to work in a mode of moving back and forth. The syringe needle is connected with an injection valve, and the injection valve is connected with a sterilizing chamber. The syringe needle moves forwards to pierce the hydrogen peroxide capsule in the elastic clip, and hydrogen peroxide is injected into the sterilizing chamber by control of the injection valve. The injecting device has the advantages of reliability and safety in injection, simplicity in structure and the like.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a hydrogen peroxide injection device on low-temperature plasma sterilizer equipment. Background technique [0002] Low temperature plasma sterilizer equipment is widely used in the sterilization of biological, pharmaceutical, medical and other industries. As the sterilizing agent of low-temperature plasma sterilizer equipment, how to safely and reliably inject hydrogen peroxide into the sterilization chamber has become the primary problem for low-temperature plasma sterilizer equipment. [0003] The hydrogen peroxide injection used in low temperature plasma sterilizers currently on the market is bottled injection and cassette injection: [0004] (1) Bottled injection is to pour hydrogen peroxide into the liquid storage tank through the metering container, and then inject hydrogen peroxide from the liquid storage tank into the sterilization chamber. The bottled injectio...
