Medical environment sterilization device

Abstract

The invention relates to the technical field of indoor sterilization equipment, and discloses a medical environment sterilization device. The medical environment sterilization device comprises a four-port communication valve, wherein two air outlet ends of the four-port communication valve respectively communicate with an ultraviolet sterilization device and a sterilization oxygenation device; twoair inlet ends of the four-port communication valve respectively communicate with an air outlet of an internal circulation type air conditioner and an air outlet of a ventilation type device; one-waycheck valve I (a) is arranged on a communication pipe of the four-port communication valve and the ultraviolet sterilization device so as to control air flow connection-and-disconnection of the ventilation type device; and a one-way check valve II (b) is arranged on a communication pipe of the four-port communication valve and the sterilization oxygenation device so as to control air flow connection-and-disconnection of the internal circulation type air conditioner. According to the medical environment sterilization device, the ultraviolet sterilization device communicates with the ventilation type device through the four-port communication valve, and the sterilization oxygenation device communicates with the internal circulation type air conditioner, so that the internal circulation typerefrigeration sterilization is mainly formed to comprehensively achieve the effects of refrigeration, sterilization, oxygen supply, moisture supplement and energy saving with assistance of carbon dioxide content reduction through periodic ventilation.

Description

technical field [0001] The invention relates to the technical field of indoor sterilization equipment, in particular to a medical environment sterilization device. Background technique [0002] To meet the needs of sterile environments such as operating rooms, wards, and nursing rooms in medical institutions, most of the current technologies are based on ultraviolet disinfection, ozone disinfection, and negative ions. Because ozone and negative ions not only have high equipment costs, but also have high-voltage safety hazards, At present, most of them still use ultraviolet disinfection, and some key aseptic environments use ethylene oxide for disinfection. Because ultraviolet rays are harmful to the human body and there are blind spots in the irradiation, it is proposed to install sterilization equipment on the air inlet of the indoor ventilator or air conditioner, install the ultraviolet lamp in the sterilization box, and use the power cycle of the ventilation equipment to ...
