The design of high-efficiency exhalation disinfection device for the patient infected with SARS / 医疗卫生装备

ABSTRACT

High-efficiency exhalation disinfection device for the patient infected with SARS can also meet the disinfection requirements of the patients with severe respiratory communicable diseases. Connected with the exhaust vent of the breathing mask or the respirator by corrugated tubes, this device gathers exhalation containing a large amount of causative agents through the completely leakproof ductwork and then expels purified air after multiplicate disinfection by high temperature, high pressure and chemical disinfectant. The device can prevent the patient with severe respiratory communicable disease from polluting their surrounding air and thus cut off the route of transmission, reduce the infection rate and the death rate of the person and medical personnel who has made intimmate contact with the patient.
