Description

Technical Field

[0001] The utility model relates to the technical field of humidification of ethylene oxide sterilizers, in particular to a humidification system of an ethylene oxide sterilizer. Background Art

[0002] The working principle of ethylene oxide (EO) sterilizer mainly depends on the chemical properties of ethylene oxide and its effect on microorganisms. Ethylene oxide is an active cyclic ether that can undergo non-specific alkylation reactions with proteins and nucleic acids in microorganisms, causing the death of microorganisms after a series of reactions. Ethylene oxide has strong penetrating power, and its sterilization effect is affected by many factors, including sterilization temperature, relative humidity, ethylene oxide concentration and action time. The sterilization process is generally divided into three stages: pretreatment, sterilization cycle and analysis. Pretreatment is the treatment of the product under specific temperature and humidity conditions.

[0003] In summary, the ethylene oxide sterilizers in the prior art are limited by factors such as the space in the cabin and the steam pipe valve, and often have excessive or insufficient humidification, as well as uneven humidification during use. These factors will lead to misjudgment of humidity detection, thereby affecting the sterilization effect; in addition, the humidification and heating of the existing ethylene oxide sterilizers are usually carried out separately, and the coordination between moisture and temperature is closely related to the sterilization effect; in view of this, there is a need for an ethylene oxide sterilizer humidification system to solve and improve the above-mentioned problems.
