Preventive disinfection measures shall be taken in clean areas, and terminal disinfection and instant disinfection measures shall be taken in semi polluted areas and polluted areas
In the final disinfection, after the shelter hospital is sealed, 30 g/L hydrogen peroxide solution or 500~1000 mg/L chlorine dioxide disinfectant aerosol spray is used for disinfection, with the spraying amount of 20~30 mL/m3 for 1 h. Or the hydrogen peroxide dry fog disinfection system shall be selected to carry out final disinfection according to the equipment operation instructions.
Shelter hospitals have been established in a short period of time to centrally treat a large number of patients with infectious diseases. There are greater risks and difficulties in hospital infection control. Through the above hospital infection prevention and control management measures, the hidden danger of cross infection in the hospital can be minimized, the health and safety of doctors and patients can be effectively guaranteed, and the centralized isolation and diagnosis and treatment work in the shelter hospital can be effectively guaranteed.
In the case of overloaded operation of hospitals and medical personnel and shortage of first-line protective materials, the medical shelter is like a “Noah’s Ark”, effectively facing various emergencies and meeting the needs of emergency medical and health rescue work in various emergencies. The role of the medical shelter in responding to the epidemic situation is obvious to all. The realization of the sterilization of plasma disinfection equipment in the shelter hospital is as follows:
- Air disinfection:
The air disinfection equipment of the plasma shelter hospital developed by Liden Environmental Protection Institute is used. The plasma disinfection equipment of the shelter hospital is equipped with a built-in disinfection device. The plasma tube of the plasma air disinfection device generates a large number of positive and negative ions. The charged ion cluster attacks the virus and bacteria actively, destroying the cell membrane, the DNA and protein of the virus, and making the air bacteria and viruses lose their activity rapidly until they are killed and decomposed. It can actively eliminate bacteria and viruses in the air, quickly eliminate bacteria and viruses in the air and other microorganisms, without causing harm to human bodies, and realize the coexistence of human and computer in a real sense.
- Disinfection of object surface
According to the nature of the object surface, disinfecting wipes, cleaning disinfectants or 3% hydrogen peroxide can be selected, sprayed or soaked for disinfection for 30min, and then washed with clean water to remove residual disinfectants.
- Disinfection of floor and wall
When there is no obvious pollution on the ground, wipe it with clean water and detergent; Clean at any time when there is obvious pollution. When the floor or wall is polluted by blood, body fluid, excreta, vomit or secretion, the pollutants shall be removed in time, and hydrogen peroxide disinfectant shall be used for mopping, wiping or spraying for disinfection for 30 minutes.
- Toilet disinfection
The toilets for patients in the shelter hospital are mostly temporary toilets, and there is no perfect sewage treatment system. The exhaust fan shall be used to enhance air exhaust, and the toilet door handle, faucet, hand wash basin, wall below 2m, floor, baffle, toilet pit or toilet shall be sprayed or wiped for disinfection, and the fecal sewage shall be treated with disinfectant.
The principle of partition and classification disinfection in the shelter hospital
Preventive disinfection measures shall be taken in clean areas, and terminal disinfection and instant disinfection measures shall be taken in semi polluted areas and polluted areas
