Composite disinfecting and sterilizing device and method

Abstract

The invention discloses a composite disinfecting and sterilizing device and method. The composite disinfecting sterilizing device comprises a cabin body, wherein a temperature, ozone concentration and humidity sensor is arranged at the top of the cabin body; a barometric pressure sensor is arranged at the bottom of the cabin body; an oxygen source is communicated with the interior of the cabin body through an ozone generator via a fourth solenoid valve; an ultrasonic humidifier is communicated with the interior of the cabin body through a second solenoid valve; a heating element is arranged at the outer side of the cabin body; one end of a peristaltic pump is communicated with H2O2; the other end of the peristaltic pump is communicated with the interior of the cabin body through a third solenoid valve; high-voltage electrode plates are oppositely arranged at two sides on the inner wall of the cabin body; and a vacuum pump is connected with the cabin body through a first solenoid valve. The disinfecting and sterilizing method comprises two alternative modes of low-temperature plasma composite hydrogen peroxide and ozone; the whole disinfecting process is intelligently controlled; and the invention has the advantages of wide application range, high sterilization speed, high inactivation ratio, no residual harm or disinfecting dead corners, convenience for use, high automatic degree and the like.

Description

technical field [0001] The invention relates to a medical disinfection and sterilization device and a disinfection and sterilization method using the device. Background technique [0002] 1. Traditional thermal sterilization technology [0003] Traditional heat sterilization is an effective sterilization method, which can kill various microorganisms, and the degree of sterilization can be accurately controlled. Although the thermal sterilization method is widely used, the high temperature required by this method can easily lead to the decomposition of heat-sensitive components and the loss of volatile components, and the energy consumption is high, which can easily damage precision medical instruments. [0004] 2. Non-thermal sterilization technology [0005] (1) Ultraviolet rays: can kill various microorganisms, including bacterial propagules, spores, mycobacteria, viruses, fungi, rickettsia and mycoplasma, etc., with a broad spectrum. The principle of sterilization is t...

AI Technical Summary

Problems solved by technology

However, low-temperature plasma also has its limitations. For example, the following items are not suitable for the use of low-temperature plasma sterilizer materials: ① disposable instruments and articles; ② liquid or powder; ③ wooden instruments; ④ cotton fabric; ⑤ gauze; ⑥ not completely dry Items

[0010] At present, the disinfection and sterilization equipment at home and abroad has a single function, mainly for decontamination of certain instruments or materials, and has a complex structure, high failure rate, and poor environmental adaptability
