The air inlet on shell is equipped with air inlet blinds; the upper part of shell is equipped with air outlet pipe; the left inner side of shell is equipped with adjustable speed motor, drive shaft connected with adjustable speed motor through belt; the antiseptic solution room in the right inner side of shell is equipped with antiseptic solution, guide shaft, and driven shaft; the drive shaft, driven shaft and guide shaft are equipped with sterilizing belt; the right side of shell is equipped with solution injecting valve and water-level gage; lower part of right side is equipped with solution discharge valve; inner right side is equipped with power for ultraviolet lamp; air inlet blinds is equipped with photocatalysis net and quartz electrothermal tube; said photocatalysis net is equipped with ultraviolet lamp; an air outlet photocatalysis net is equipped in shell; air outlet is equipped with active char filtering blanket and axial fan; a control board is installed on shell. The invention is characterized by rational design, simple structure, fast sterilizing speed, high efficiency and thorough sterilization. It is can be used for sterilization of ward and operating room and discharging of toxic gas in laboratory.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and in particular relates to a wall-mounted air disinfection device for a respiratory infection ward. Background technique [0002] Air disinfection and purification in respiratory infection wards has always been the top priority of hospital disinfection. Its purpose is to prevent virus infection and spread among patients, between patients and medical care and accompanying staff, and between respiratory wards and the outside world. At present, the air disinfection and purification of wards mainly adopts ozone disinfection, ultraviolet disinfection, ultrasonic atomization of various disinfectants 12 disinfection and various independently operated air disinfection and purification machines. The previous disinfection instruments can achieve a certain effect, but the person must leave the ward or the patient must be strictly protected during disinfection, and the disinfection is often carr...
