Sterilization method with gasified hydrogen peroxide

Abstract

The invention relates to the technical field of sterilization, in particular to a gasified hydrogen peroxide sterilization formula. The technical scheme adopted in the present invention is: a gasification hydrogen peroxide sterilization method, which is characterized in that it consists of four stages, wherein the first stage is a dehumidification preheating stage, the second stage is a gas injection stage, and the third stage It is the sterilization stage, and the fourth stage is the residue removal stage; in the first stage, the dehumidifier is turned on to reduce the humidity in the cavity, and the heating plate is turned on at the same time to heat up the evaporation chamber. When the temperature reaches the set value, the heating plate keeps Low temperature heating to ensure the temperature of the evaporation chamber is stable, when the humidity reaches the set value, this stage ends. The advantages of the present invention are: using vaporized hydrogen peroxide for sterilization, short process time, good compatibility with materials, easy verification, better and more thorough sterilization effect, preventing environmental pollution, and sterilizing pharmaceutical equipment. The effect is better and it is more convenient to use.

Description

Technical field [0001] The present invention relates to the field of sterilization technology, in particular to a method for sterilizing vaporized hydrogen peroxide. Background technique [0002] Sterilization has always been a key link in the production of sterile products. With the implementation and promotion of the new version of GMP, the requirements for the production of sterile drugs continue to increase. In order to improve the quality of drugs and the health of the Chinese people, choose effective and safe , Environmentally friendly sterilization method is very important. Gas Hydrogen Peroxide (GHP, GAS Hydrogen Peroxide) has a broad-spectrum antimicrobial performance, and has a good sterilization effect on fungi, molds, viruses, gram bacteria, especially anaerobic bacillus. After the vaporized hydrogen peroxide is degraded, it will decompose into oxygen and water, which is harmless to personnel and the environment.

AI Technical Summary

Problems solved by technology

[0003] Formaldehyde fumigation is to vaporize formaldehyde or formalin by heating, the effect is relatively slow, and it takes a long time to fumigate. After fumigation, there will be crystalline white powder residue, which is troublesome and incomplete. Toxic chemicals and classified as "Class A" substances that cause cancer and cell mutation. With the improvement of human health requirements, formaldehyde will be restricted as a clean room sterilant. Therefore, formaldehyde must be replaced

[0004] Ozone has strong oxidation-reduction and corrosiveness, and it will cause irreversible damage to the human body after inhalation. The decomposition speed of ozone is very fast, and the sterilization effect in complex spaces is very poor.
