Ethylene oxide preheating, sterilization and resolution integrated cabinet and sterilizing method

Abstract

The invention relates to an ethylene oxide preheating, sterilization and resolution integrated cabinet and a sterilizing method. The integrated cabinet comprises a cabinet body, wherein a sealing door is arranged on the front part of the cabinet body; a cavity in the cabinet body is connected with a vacuum pump through a vacuumizing pipeline; the cavity in the cabinet body is connected with a humidifying device through a humidifying pipeline; the cavity in the cabinet body is connected with wet and hot air making devices through wet and hot air delivery pipelines; a heating water jacket is arranged outside the cabinet body; a circulating air pipeline is arranged on the outer side of the cabinet body; a fan is connected in series to the circulating air pipeline; an air inlet of the circulating air pipeline is arranged on one side in the cabinet body; an air outlet of the circulating air pipeline is arranged on the other side in the cabinet body; and the cabinet body is connected with an ethylene oxide container through a pipeline provided with a valve. The ethylene oxide preheating, sterilization and resolution integrated cabinet has the advantages of high operating efficiency, few matched facilities, low fault rate, short construction period, low daily using cost and low energy loss, and can reduce pollution to human body and environment and improve the comprehensive benefit by over 40 percent.

Description

technical field [0001] The invention relates to an ethylene oxide preheating, sterilization and analysis integrated cabinet and a sterilization operation method. Background technique [0002] The products produced by medical supplies companies must be sterilized to reach a sterile state before they can be sold on the market. The existing medical supplies sterilization system is usually divided into three parts, one is the preheating room, and the other is the sterilization cabinet. , The third is the analysis room. The sterilization method adopts ethylene oxide to sterilize. The characteristics of ethylene oxide are flammable, explosive, and strong penetrability. Fumigation of the product for a certain period of time in a relatively low temperature and humidity can achieve the purpose of sterilization . However, ethylene oxide also has certain harm to the human body, and it may even cause personnel poisoning when the concentration is high. [0003] Ethylene oxide steriliz...

AI Technical Summary

Problems solved by technology

Moreover, according to the normal configuration, the number of preheating rooms is twice that of the sterilizer, and the analysis room is 4-6 times that of the sterilizer, which increases the construction area of ​​the plant, the supporting facilities, the input cost, the number of staff, and the workload. The failure rate increases, the management cost increases, the construction period increases, the verification use performance cycle increases, and the daily use cost increases
