Field of the invention

The invention belongs to the field of medical disinfection, and particularly relates to a telescopic positive and negative pressure disinfection method for a large-scale chamber, which is suitable for large-scale places needing microorganism disinfection, such as sterile rooms, operating rooms, sickrooms, laboratories and the like of hospitals and scientific research institutions.

Background

At present, the microbial disinfection in large-scale places such as wards of hospitals and scientific research units, operating rooms, laboratories and the like mainly has two modes, namely a conventional static disinfection mode and a dynamic filtration mode. The so-called conventional static disinfection is to evacuate personnel in large places such as laboratories, operating rooms, sickrooms and the like to be disinfected, then open disinfection facilities for disinfection, and after a certain time period to determine that microorganisms are completely killed, patients or workers can enter the disinfection facilities, but in actual operation, because many disinfection modes have certain toxic gas residues, such as ozone disinfection, ultraviolet disinfection and the like, ozone can remain for as long as 30 minutes, and the disinfection mode is not suitable for online disinfection. Another filtration sterilization method is suitable for on-line sterilization, but the device is complicated and expensive, and the sterilization effect is not ideal, so the application is limited.

Disclosure of Invention

The invention relates to a telescopic positive-negative pressure large-scale chamber disinfection method, which is suitable for any large-scale place needing disinfection and any mode of disinfection, and is particularly suitable for the online dynamic disinfection of hospitals under the condition that the normal hospitalization of patients and the normal operation and scientific research of workers are not influenced, namely, the telescopic positive-negative pressure large-scale chamber disinfection method has the unique advantages of infectious disease wards needing negative pressure disinfection, laboratories with high risk of leakage, and the dynamic disinfection of common operating rooms and laboratories needing positive pressure. The invention is that a telescopic disinfection chamber with telescopic volume is arranged beside a large place needing disinfection, such as a ward, an operating room, a laboratory and the like, and the telescopic disinfection chamber is communicated with the large place to be disinfected, such as the ward, the operating room, the laboratory and the like, through a pipeline, and disinfection facilities are arranged in the telescopic disinfection chamber and expand or contract along with the increase and decrease of the internal gas pressure. When air in an infectious disease ward needs negative pressure sterilization, the air in a place to be sterilized is sucked into the telescopic sterilization chamber through the air pipeline, the size of the telescopic sterilization chamber is increased from small to a set value along with the increase of the air pressure, a sterilization facility is started for sterilization, and after all microorganisms are killed for a certain time, the air is discharged out of the room. On the contrary, for places such as operating rooms requiring positive pressure sterilization, outdoor air is firstly sucked into the telescopic sterilization chamber, the size of the telescopic sterilization chamber is increased until the telescopic sterilization chamber reaches a set value in the suction process, then the sterilization facilities in the telescopic sterilization chamber are started to kill microorganisms in the telescopic sterilization chamber, and then the gas in the telescopic sterilization chamber is sent to the places such as the operating rooms and laboratories requiring clean gas through the air pipeline.

The specific technical scheme adopted by the invention is that at least one or more telescopic disinfection chambers are arranged near a fixed conventional sterile chamber, the fixed conventional sterile chamber and the telescopic disinfection chambers are communicated by an air pipeline, an air pipeline between the telescopic disinfection chambers and the fixed conventional sterile chamber is provided with an exhaust fan, the exhaust fan is used for exchanging air in the telescopic disinfection chambers and the fixed conventional sterile chamber, disinfection facilities are arranged in the telescopic disinfection chambers, the telescopic disinfection chambers are also provided with air exchange fans, the fixed conventional sterile chamber is provided with air regulating valves, and the telescopic disinfection chambers expand or contract along with the increase and decrease of the internal air pressure; the disinfection facilities in the telescopic disinfection chamber comprise, but are not limited to, ultraviolet disinfection, ozone disinfection, high-temperature disinfection, chemical liquid atomization disinfection and chemical liquid spray disinfection, and all the conventional disinfection facilities are used singly or in combination.
