In fact, ethylene oxide sterilizer is the key equipment for disposable sterile medical device manufacturers. It has special requirements for installation, operation and use management. Ethylene oxide is used as a sterilant. Ethylene oxide is a widely used Spectrum sterilizer, which can kill various microorganisms at room temperature, including spores, Mycobacterium tuberculosis, bacteria, viruses, fungi, etc.

There are four key parameters: gas concentration, relative humidity, sterilization temperature and sterilization time. Ethylene oxide sterilization has been widely used in disinfection supply centers due to its good effect, good compatibility, less damage to equipment, relatively low cost, and complete monitoring methods.

gas concentration. Within a certain range, the bactericidal efficacy of ethylene oxide increases with the increase of gas concentration. If using 100 percent pure ethylene oxide gas canisters, using one canister at a time will ensure sufficient gas concentration. The concentration of ethylene oxide gas cannot be directly monitored, but can be estimated from the gas pressure sensed by the probe. The initial drop in gas pressure is due to the evacuation process. With the puncture of the EO gas tank, ethylene oxide gas is released to keep the gas pressure constant, which is the plateau period. Ventilation is then performed, and the air pressure also decreases as the ethylene oxide is expelled or increases as fresh air is injected. China Ethylene Oxide Scrubber Factory is worth noting that the red curve is always below the straight line of "standard atmospheric pressure", so as to ensure that ethylene oxide gas will not leak during the whole process.

Ethylene oxide sterilization is to sterilize items, which can kill several kinds of microorganisms. It is more hygienic and healthier for medical devices that are in direct contact with human tissues and blood, and it is more secure to use. Since the gauze sheet is in direct contact with the wound and blood, it is more healthy and hygienic to use the gauze sheet sterilized by ethylene oxide, and it is more assured to use.

Sterilized grade products can be used directly, and it is forbidden to use ordinary gauze directly after the package is damaged; it must be used after sterilization; when the product properties change (moisture absorption, yellowing, mildew), it is forbidden to use; this product is a disposable product and cannot be reused ; It should be prohibited to use beyond the expiration date.
