Medical instrument sterilization and disinfection device and method based on low-temperature plasma

Abstract

The invention provides a medical equipment disinfection box based on low-temperature plasma at normal temperature, universal wheels are mounted at the bottom of a box body, and the medical equipment disinfection box is characterized in that: the box body comprises a low-temperature plasma generating device module, an airflow control module, a motor driving module and a power supply module. Specifically, the plasma generating device module comprises a discharge assembly and a plasma generator; the airflow control module comprises an air tank, an airflow controller and an air washing device; the motor driving module comprises two motors and is used for controlling the plasma generator and a to-be-processed equipment clamp to move. excited state and metastable state high-energy active particles of various electrons, ions, active oxygen, active nitrogen and inert gas molecules in the plasma act on the medical instrument, bacteria and viruses on the surface of the equipment are removed, sterilization and disinfection of the medical instrument are achieved, the whole process is in a normal temperature state, and no damage is generated to the equipment.

Description

technical field [0001] The disclosure belongs to the technical field of low-temperature plasma sterilization equipment, and in particular relates to a low-temperature plasma-based medical device sterilization and disinfection device and method. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art. [0003] Traditional sterilization methods mainly use heat, chemistry and radiation to inactivate bacteria. Emerging sterilization methods use new methods such as ultra-high pressure, ultrasonic waves, pulsed electric fields and low-temperature plasma to sterilize. These methods have their own advantages and disadvantages, some can reach the level of disinfection (3 orders of magnitude reduction in the number of colonies), and some can reach the level of sterilization. However, the traditional sterilization methods have disadvantages such as the limitation o...

AI Technical Summary

Problems solved by technology

However, the traditional sterilization methods have disadvantages such as the limitation of the sterilization space or the addition of toxic chemicals, and they may also affect the surrounding environment during sterilization, and the sterilization time is long and the efficiency is low.
