Method for preventing viral infection in infection sickroom air by using cabin type air conditioning unit

Abstract

The invention discloses a method for preventing viral infection in infection sickroom air by using a cabin type air conditioning unit, and belongs to a method for preventing viral infection in the technical field of air purification. In order to provide the method for preventing the infection of the viruses in the infection sickroom air by using the cabin type air conditioning unit, the cabin type air conditioning unit is included, the cabin type air conditioning unit comprises a clean cabin, a first air pipe and a second air pipe, the first air pipe and the second air pipe are arranged at the two ends of the clean cabin respectively, the first air pipe is internally provided with an ultraviolet lamp, an ozone device is arranged in the second air pipe, and an air inlet end of the first air pipe and an air inlet end of the second air pipe are connected with a fresh air purification device; a valve on an air outlet pipe is closed, a draught fan on the first air pipe or on the second air pipe is opened; the air first enters the first air pipe and treated by means of the ultraviolet lamp, and the disinfected and sterilized air enters the clean cabin; the air in the clean cabin enters the second air pipe, disinfected and sterilized through the ozone device, and then discharged outward.

Description

technical field [0001] The invention belongs to the technical field of air purification, and relates to a method for preventing virus infection, in particular to a method for preventing virus infection by using a cabin air-conditioning unit. Background technique [0002] With the improvement of people's living standards, air quality has become a concern of people. As we all know, various viruses and bacteria are invading human beings all the time on the earth we live on. In order to remove indoor pathogenic substances, such as bacteria, viruses, and fungi, ultraviolet light is generally used to disinfect and sterilize indoor spaces. Ultraviolet light is commonly used in operating rooms, dispensing rooms, etc. in hospitals. [0003] In the operating room, patients have extremely strict requirements on the air cleanliness in the operating room. In the prior art, in order to fill the operating room with clean air and effectively prevent the air in the operating room from cont...

AI Technical Summary

Problems solved by technology

However, although the medical staff also undergo simple disinfection before entering the operating room, as the operation proceeds, the sweat of the medical staff and the body parts separated from the body will bring bacteria and viruses on the medical staff into the operation. In the air in the room, it is very easy to cause infection of the patient during the operation

Since the clean air is blown down from the ceiling at the top of the operating room, and in the prior art, in order to reduce the bacteria and viruses in the air in the operating room to infect the patient's surgical incision, the air outlet on the ceiling is usually set in the operating room It is directly above and corresponds to the position of the patient's surgical incision; therefore, during normal operations, when the clean air is blown from top to bottom, the clean air can easily separate the sweat of the medical staff and the body from the body. Viruses and bacteria are taken away and directly act on the patient's surgical incision, increasing the probability of infection of the patient's surgical incision

In addition, when the sterilized and sterilized clean air is usually at room temperature, the clean air usually performs Brownian motion in the operating room after entering the operating room, so that the clean air will quickly spread to all corners of the operating room, and the same as the original The air in the operating room is mixed. When the original air contains bacteria or viruses, filling in clean air will have a weak effect on maintaining a non-toxic and sterile environment in the operating room.

The above-mentioned technical problems do not only appear in the operating room. Similar problems still exist in the common infectious disease ward. The bacteria and viruses in the infectious disease ward or the bacteria and viruses brought into the ward by medical staff will seriously restrict the patient. recovery, and the bacteria and viruses carried or produced by infectious disease patients will also pose a risk of infection to medical staff and the patient's family members
