Preferably, the square cabin also comprises a plasma air purifier, a packaging platform, a sealing machine, a notebook workstation, an air conditioner, a field folding chair, a field folding table, a folding goods shelf, an illuminating lamp, temperature and humidity, a fire extinguisher, an air exchange fan and the like.
The operating flow scheme of the disinfection and sterilization shelter is as follows:
1. the disinfection and sterilization shelter advises personnel to allocate 2 persons, and 1 person respectively in a clean area and a decontamination area;
2. after personnel enter, the positive and negative pressure devices are started to form differential pressure gradient protection in each area in the cabin;
3. the materials to be sterilized enter from the buffer area in the cabin and enter the decontamination area through the buffer area and the decontamination area separation door;
4. after the materials enter the decontamination area, placing the articles to be treated on a classification platform for classification;
5. cleaning, disinfecting and drying the articles which can be treated by the cleaning equipment by using the cleaning equipment according to the equipment use instruction; articles which cannot be treated by the cleaning equipment can be treated in the cleaning tank;
6. delivering the cleaned, sterilized and dried articles to a clean area through a delivery window, and performing classified packaging on a clean area packaging table;
7. according to the characteristics of the sterilized article, a low-temperature hydrogen peroxide plasma sterilizer and a pressure steam sterilizer which are suitable for the sterilization are selected for sterilization treatment.
8. The article after the sterilization can be kept in the clean area temporarily, and is transmitted through the buffer area between the clean area and the medical staff passage during use.
The disinfection and sterilization shelter designed by the invention meets the requirements of the relevant standards of the health council of students, realizes the physical isolation subareas of a decontamination area, a cleaning area and a buffer area in a 6m single-expansion shelter, and is respectively provided with a positive pressure device and a negative pressure device in the decontamination area and the cleaning area, realizes the subarea pressure difference isolation function in the shelter, can realize the pressure difference gradient of not less than 5Pa-20 Pa between three areas in the shelter, realizes the directional flow function of airflow from the cleaning area to the decontamination area, realizes the directional flow of materials and personnel by the design of doors and transfer windows in each area in the shelter, and furthest reduces the possibility of cross infection in the disinfection and sterilization operation process.
