Description

Technical Field

[0001] The present invention relates to the technical field of biosafety disinfection equipment, and particularly to an integrated transfer type fumigation device and disinfection method for protective appliances. Background Art

[0002] The disinfection and sterilization of protective appliances is a necessary prerequisite for reuse. Taking the positive pressure biological protection hood as an example, the positive pressure biological protection hood is a reusable personal protective equipment that can provide high-level safety protection for the head and respiratory tract of personnel. During the operation of pathogenic microorganisms, the positive pressure biological protection hood is extremely vulnerable to contamination by pathogenic microorganisms. Usually, it needs to be disinfected comprehensively after use before it can be safely used by others again. The positive pressure biological protection hood mainly consists of a hood body, an air supply pipeline, and a power supply air filtration device. In the early stage, it was mainly disinfected by methods such as soaking, spraying, and wiping with disinfectant solution. At the same time, in order to remove the residual disinfectant solution, it was also necessary to wash, dry, and disinfect with clean water. The process was extremely cumbersome, and there was a risk of exposure for operators during the disinfection process. At the same time, in some biosafety protection facilities, such as negative pressure isolation wards, biological product workshops, etc., there are independent channels for personnel to enter and exit, and the donning and doffing of the positive pressure biological protection hood are usually located in different rooms. In order to reuse the hood, a complex item transfer process is also required.

[0003] Therefore, in view of the problems of disinfection and transfer in the safe reuse of the positive pressure biological protection hood, there is an urgent need to develop an integrated transfer type fumigation device for protective appliances. Summary of the Invention

7. The integrated transfer type protective appliance fumigation device according to claim 1, characterized in that: A temperature sensor and a VHP sensor are arranged in the disinfection chamber, the temperature sensor is used to measure the temperature in the disinfection chamber, and the VHP sensor is used to measure the concentration of the disinfectant in the disinfection chamber and the humidity in the disinfection chamber.

8. A disinfection method using the integrated transfer type protective appliance fumigation device according to any one of claims 1-7, characterized in that: It includes the following stages: The first stage includes a ventilation process and a dehumidification process. First, the ventilation process is carried out, and then the ventilation process and the dehumidification process are alternately carried out until the temperature sensor detects that the temperature in the disinfection chamber and the VHP sensor detects that the humidity in the disinfection chamber reach the set values. At the same time, the generating device works for preheating; When carrying out the ventilation process, compressed air sequentially passes through a first pressure reducing valve, a first filter, a compressed air solenoid valve, and an air supply filter and enters the disinfection chamber, and then sequentially passes through an air outlet valve, an exhaust valve, an exhaust filter, and an exhaust manual valve and is discharged to realize ventilation; When performing the dehumidification process, close the first pressure reducing valve and the exhaust valve, open the circulation valve, operate the second circulation fan, and operate the pipeline heater to achieve heating of the internal circulation. The heated gas passes through the main pipe and each branch pipe and enters the disinfection chamber; In the second stage, the dehumidification process continues. At the same time, open the disinfection exhaust valve, operate the first circulation fan, start the generating device to vaporize the disinfectant liquid to form disinfection gas, open the disinfection inlet valve, start the metering pump, and the metering pump operates according to the working set value and working time. The disinfection gas enters the disinfection chamber. At the same time, under the action of the circulation pipeline, the disinfection gas enters each branch pipe through the main pipe to disinfect the protective equipment to be disinfected; In the third stage, the working frequencies of the first circulation fan and the second circulation fan are changed according to the set value, and the working set value of the metering pump is changed to make the disinfection gas in the disinfection chamber more uniform; In the fourth stage, close the disinfection exhaust valve, open the residue removal valve, stop the metering pump and the generating device. The disinfection gas in the disinfection chamber passes through the residue removal tank, the residue removal valve, and the disinfection inlet valve under the action of the first circulation fan. At this time, the circulation pipeline continues to be open, and the working frequency of the second circulation fan changes in real time until the concentration of the disinfection gas in the disinfection chamber is reduced to a certain value; In the fifth stage, when the VHP sensor detects that the concentration of the disinfection gas in the disinfection chamber is reduced to a certain value, close the circulation pipeline, open the exhaust valve and the air supply valve. The gas passes through the air supply valve and the air supply filter into the disinfection chamber in sequence, and then is discharged through the air outlet valve, the exhaust valve, the exhaust filter and the exhaust manual valve.
