In order to improve the disinfection effect of vaporized hydrogen peroxide sterilizer in blood transplantation ward; Through the statistical big data analysis of the disinfection effect of vaporized hydrogen peroxide disinfection machine in the blood transplantation ward; Quantitative monitoring of the efficacy of vaporized hydrogen peroxide sterilizer in blood transplantation ward; A monitoring method for disinfection effect of vaporized hydrogen peroxide sterilizer in blood transplantation ward based on big data analysis is proposed; To build a big data statistical average analysis model for the disinfection effect of vaporized hydrogen peroxide disinfection machine in the blood transplantation ward; Combined with the method of sample regression analysis, the segmented sample regression analysis of the disinfection effect of vaporized hydrogen peroxide disinfection machine in the blood transplantation ward was carried out; The decision-making objective function for evaluating the efficacy of vaporized hydrogen peroxide sterilizer in blood transplantation ward was constructed; The method of fuzzy decision evaluation was used to quantitatively analyze the cross infection items of the efficacy of vaporized hydrogen peroxide disinfection machine in the blood transplantation ward;
During the sterilization process of the sterilization/ventilation double cycle technology, hydrogen peroxide steam will not be lost through the catalyst and dryer, with low hydrogen peroxide consumption and short decomposition time. The circulation process is closed without exhaust gas, and the maximum sterilizable capacity of reagents saved is not less than 400m3. The gas flow is not less than 400m3. The hydrogen peroxide liquid injection rate is 10~20g/min, the air flow is 30~50 m3/h, the sterilization space temperature is 15~35 ℃, the sterilization space humidity is not more than 80%. The control system uses Siemens PLC, and is equipped with data RS485 or RS232 interfaces, which is convenient for remote PLC control and data download. H2O2 liquid reagents are opened, Domestic H2O2 liquid H2O2 storage tank with a concentration of 30% – 35% W/W ≥ 4L can be used, which can at least meet the consumption of the largest sterilization space at one time, without stopping the machine in the middle
