Ventilation device for hospital infectious disease department ward

Abstract

The invention discloses a ventilation device for a hospital infectious disease department ward. The ventilation device comprises an exhaust device, an adsorption filtration treatment device, a disinfection treatment device and a gas-liquid separation device, wherein the adsorption filtration treatment device is communicated with the exhaust device; the disinfection treatment device comprises a disinfection box, an atomization generator and an atomization spray pipe; the disinfection box is provided with a first cavity and a second cavity; the second cavity is provided with an air inlet and an exhaust port; the air inlet is communicated with the adsorption filtration treatment device; the atomization generator is arranged in the first cavity; the atomization spray pipe is arranged in the second cavity and communicated with the first cavity; and the gas-liquid separation device is communicated with the exhaust port. According to the ventilation device for the hospital infectious disease department ward provided by the embodiment of the invention, air in the ward can be effectively sterilized and disinfected and then exhausted, the treated air is cleaner and safer, and the infectious risk in the environment is reduced.

Description

technical field [0001] The invention relates to an air treatment device, in particular to a ventilation device for a ward of a hospital infectious disease department. Background technique [0002] For some departments with infectious diseases, patients are active in the ward, and there may be infectious viruses and other harmful substances in the air of the ward, such as tuberculosis patients, tuberculosis is a chronic infectious disease caused by Mycobacterium tuberculosis, which can invade many Organs, pulmonary tuberculosis infection is the most common, and bacteria excretion is an important source of infection, mainly through droplets, saliva and other means of transmission. Therefore, the air exchange units in such wards need to process the air. At present, the ventilation devices used in hospitals generally use physical filtration to filter the air in the ward and then discharge it. This method is less effective, and there is still a greater risk of infection to other...

Problems solved by technology

At present, the ventilation devices used in hospitals generally use physical filtration to filter the air in the ward and then discharge it. This method is less effective and there is still a greater risk of infection to other environments after discharge.
