Description

Compound sterilizing machine

Technical Field

The invention relates to a composite type disinfection machine.

Background

The terminal disinfection refers to one-time complete disinfection of the epidemic point after the infectious source leaves the epidemic point or terminates the infectious state after being hospitalized, transferred and killed. Aims to completely eliminate the living pathogens which are scattered by the patient and left on the living room and various objects, and to make the epidemic spots harmless. The final disinfection in hospitals is mainly the final disinfection in isolation wards or rooms, and meanwhile, if patients are examined or diagnosed in other places such as CT rooms, operating rooms, transfer ambulances and the like, the final disinfection in the places is also very important and necessary, which is relevant to the occupational safety of medical staff and the diagnosis and treatment safety of subsequent patients. Especially, the new crown epidemic situation generates a large number of confirmed or suspected infected patients in a short time, so that people pay more attention to terminal disinfection, and especially the effect of the terminal disinfection is more concerned.

The final disinfection mode commonly used in medical institutions at present is manual cleaning and wiping and air disinfection, and chemical disinfection modes (such as spraying or atomizing of hydrogen peroxide, peracetic acid, chlorine-containing disinfectants and the like) and ultraviolet lamp irradiation disinfection are used in special periods. These means are common and mature disinfection methods and are used in various medical environments of many medical institutions, but unfortunately, many medical institutions cannot standardize the terminal disinfection method, so that a good terminal disinfection effect cannot be achieved. The conventional terminal disinfection modes also have various advantages and disadvantages, for example, ultraviolet rays and hydrogen peroxide generally cannot coexist in a man-machine mode during terminal disinfection, and plasma cannot achieve a good disinfection effect on an object surface.
