Portable micro-plasma sterilizer

Abstract

The invention provides a portable micro-plasma sterilizer, and relates to a non-equilibrium plasma type spray germicidal disinfectant generation device. The device comprises a mainframe 1 and a plasma sprayer 2. The mainframe comprises a housing 6, a high-tension transformer 7, a water pump 9, a flowmeter 10, and the like; the plasma sprayer comprises an insulator cover 18, a knife structure metal electrode 24, a water vapor atomizing nozzle 26 and the like. Disruptive discharge arcs are formed in the minimum distance position between electrodes by virtue of high-voltage potential difference between metal electrodes in the plasma sprayer; the disruptive discharge arcs quickly glide downstream along the surfaces of the electrodes under the driving of a water-vapor mixture generated by the atomizing nozzle and pulsed gliding arc non-equilibrium plasmas are formed on the surfaces of the electrodes, and therefore, a water-vapor mixture containing oxidizing particles such as hydrogen peroxide, ozone, hydroxyl radicals and oxygen radicals is generated; and the water-vapor mixture is jetted out from the insulator cover to form a water-vapor spray germicidal disinfectant.

Description

technical field [0001] The invention relates to a sterilization and disinfection generating device, in particular to a portable micro-plasma sterilizer. Background technique [0002] With the development of medicine and biotechnology and the widespread use of polymer medical devices, the existing ethylene oxide, formaldehyde, and steam sterilization can no longer meet some special needs in terms of efficacy and environmental impact, and it is urgent to find new sterilization methods. method to sterilize some heat-sensitive substances at low temperature. The ideal sterilization technology should have the following properties: 1) The sterilization time should be as short as possible, at least less than the traditional thermal sterilization method; 2) The temperature during sterilization should be lower than 50°C; 3) It can meet the sterilization needs of various objects; 4) The entire sterilization process should be harmless to operators, patients and objects to be sterilized...

AI Technical Summary

Problems solved by technology

Traditional plasma sterilization equipment mostly adopts low-pressure radio frequency discharge plasma method. The vacuum range generated by plasma is in the range of several Pa to tens of Pa. The manufacturing cost and operating cost of plasma equipment are relatively high.
