Hydrogen peroxide double-temperature vaporizing device of low-temperature plasma sterilizer

Abstract

The invention relates to a hydrogen peroxide double-temperature vaporizing device of a low-temperature plasma sterilizer, belonging to the technical field of medical disinfection and sterilization. The vaporizing device comprises a high-temperature vaporizing chamber main body and a low-temperature vaporizing chamber main body, wherein the low-temperature vaporizing chamber main body is located above the high-temperature vaporizing chamber main body, and a high-temperature vaporizing chamber and a low-temperature vaporizing chamber are respectively arranged in the high-temperature vaporizing chamber main body and the low-temperature vaporizing chamber main body; a hydrogen peroxide inlet is arranged on the high-temperature vaporizing chamber, a hydrogen peroxide outlet is arranged on the low-temperature vaporizing chamber, and a heating rod and a temperature probe are arranged on the high-temperature vaporizing chamber main body. The vaporizing device has the main structural characteristics that the high-temperature vaporizing chamber main body and the low-temperature vaporizing chamber main body are connected into a whole by arranging a heat isolating cushion and a heat conducting screw between the two main bodies, a gas heat isolating block is installed between the high-temperature vaporizing chamber and the low-temperature vaporizing chamber, a gas channel is arranged in the gas heat isolating block, and a heat dissipating sheet is arranged on the low-temperature vaporizing chamber main body. The invention has the advantages of simple structure, low cost and good application prospect, and is applicable to popularization and use in the filed of medical sterilizers.

Description

technical field [0001] The invention belongs to the technical category of medical disinfection and sterilization, and in particular relates to a hydrogen peroxide dual-temperature vaporization device for a low-temperature plasma sterilizer. Background technique [0002] With the development of medical and biological high-tech, the existing sterilization technology can no longer meet some special needs. Some precision medical instruments that are not resistant to high temperature, such as various endoscopes, fiberscopes, batteries, electric knife wires and Other materials that are sensitive to heat and humidity require low-temperature sterilization technology. Plasma sterilization technology is another new low-temperature sterilization technology after methane, ethylene oxide, glutaraldehyde and other sterilization technologies. The low-temperature plasma sterilization technology has almost all the conditions that an ideal sterilization method should have: compared with high...

AI Technical Summary

Problems solved by technology

The hydrogen peroxide vaporization device in the previous low-temperature plasma sterilizer uses two vaporizers to turn the hydrogen peroxide liquid into a gaseous state and transmits it to the sterilization chamber. Since the two vaporizers have different temperatures, two sets of temperature control systems are required Control the temperature of each vaporizer separately, the device is too complicated and the cost is high
