The chemical disinfection method that belongs to the chemical disinfection method is ethylene oxide sterilization.
Chemical disinfection refers to the use of chemical disinfectant drugs to act on microorganisms and pathogens, so that their proteins are denatured, lose normal function and die. Commonly used chlorine disinfectants, oxidizing disinfectants, iodine disinfectants, aldehyde disinfectants, heterocyclic gas disinfectants, phenolic disinfectants, alcohol disinfectants, quaternary amine disinfectants and so on.
Ethylene oxide sterilization device is the key equipment of single-use sterile medical device manufacturers, installation and operation, use and management of its special requirements, the use of ethylene oxide as a sterilizing agent, ? Ethylene oxide is a broad-spectrum sterilizing agent, which can kill various microorganisms at room temperature, including bacillus, tubercle bacillus, bacteria, viruses, fungi and so on.
Test equipment
(1) Bacillus subtilis black variant (ATCC?9372) bacillus tablets.
The bacterial content is required to be 5×10cfu/tablet to 5×10cfu/tablet. In the amount of ethylene oxide 600mg/L±30mg/L, temperature of 54 ℃±2 ℃, relative humidity of 60%±10% conditions, the bacterial piece on the bacterial spore survival time should be ≥7.8min, killing time ≤ lift dust register 58min, positive macro D value of 2.6min~5.8min.
(2) dyeing carriers (10mm×10mm), to the cloth sheet as a Representative, if necessary, with the sterilization object, additional or change to other carriers.
(3) polyethylene plastic bag (encapsulation of slices of bacteria, the size of 60mm × 40mm, 0.2mm ~ 0.4mm thick).
(4) live bacteria culture counting equipment required, the use of instructions for the use of the sterilizer can handle the items.
