Vaporized hydrogen peroxide sterilizer

Abstract

The invention relates to the technical field of medical disinfection and sterilization, and in particular to a vaporized hydrogen peroxide sterilizer. The sterilizer comprises a shell, wherein an upper end of the shell is rotatably connected with a rotating diffuser head, inside of the shell is provided with a hydrogen peroxide storage tank, a liquid level sensor, a liquid pump, a mixing tank, a fan, a vacuum pump, a battery, and an electric heating tube, and a dual-axis motor is provided in the rotating diffuser head; one side wall of the shell is fixedly connected with a singlechip control panel, the singlechip control panel is provided with a display screen, the other side wall of the shell is provided with a maintenance port, and the upper end of the maintenance port is hinged with a cover plate. The sterilizer has compact structure and low cost, is convenient to carry and is suitable for popularization and use.

Description

technical field [0001] The invention relates to the technical field of medical disinfection and sterilization, in particular to a vaporized hydrogen peroxide sterilizer. Background technique [0002] Hydrogen peroxide (hydrogen peroxide), chemical formula H2O2. Pure hydrogen peroxide is a light blue viscous liquid that can be miscible with water in any proportion. It is a strong oxidant. The aqueous solution is commonly known as hydrogen peroxide and is a colorless transparent liquid. Its aqueous solution is suitable for medical wound disinfection, environmental disinfection and food disinfection. Under normal circumstances, it will slowly decompose into water and oxygen, but the decomposition speed is extremely slow. The way to speed up its reaction speed is to add a catalyst - manganese dioxide, etc. or irradiate with short-wave radiation. [0003] The use of hydrogen peroxide is divided into three types: medical, military and industrial. Daily disinfection is medical hy...

AI Technical Summary

Problems solved by technology

[0004] With the advancement of hydrogen peroxide application technology in the field of sterilization and the continuous expansion of information transmission, vaporized hydrogen peroxide and dry mist hydrogen peroxide are more and more widely used in practical applications, in sterile pharmaceutical companies, biological laboratories, animal rooms , medical institutions, disease control systems, emergency systems and other applications are gradually being promoted, and the effect of use has also been recognized by everyone. In some radiopharmaceutical manufacturers, the scale is generally small and the production frequency is high, which is not suitable for large and expensive hydrogen peroxide extinguishers. Bacteria

[0005] And the existing vaporized hydrogen peroxide sterilizer is bulky, not easy to carry, and the manufacturing cost is high, so it is expensive

[0006] Moreover, the existing vaporized hydrogen peroxide sterilizer has a fixed mist angle, which is not conducive to the diffusion of hydrogen peroxide vapor, and the sterilization range is small and the effect is not good
