Description

Respiratory infectious disease isolation device

Technical Field

The invention relates to the field of medical air purification, in particular to a respiratory infectious disease isolation device.

Background

Respiratory infectious diseases refer to infectious diseases caused by invasion of pathogens from respiratory tract infections such as nasal cavities, throats, tracheas, bronchi and the like of human bodies, and respiratory tract infections occur due to the fact that respiratory tracts are communicated with the outside and are frequently attacked by various pathogens. Common respiratory infectious diseases comprise influenza, measles, tuberculosis and the like, the novel coronavirus pneumonia which is outbreaked in 2020 is proved to be acute respiratory infectious diseases caused by 2019 novel coronavirus infection, and epidemic prevention experts emphasize that the determined novel coronavirus transmission paths mainly comprise direct transmission, aerosol transmission and contact transmission.

Direct transmission refers to infection caused by sneezing, coughing, speaking droplets and direct inhalation of exhaled air in close proximity; aerosol transmission refers to the mixing of droplets in the air to form an aerosol which causes infection after inhalation; contact transmission refers to the condition that droplets are deposited on the surface of an article and contact with mucous membranes such as oral cavity, nasal cavity, eyes and the like after contacting with contaminated hands, so that infection is caused.

The exposure risk is very big in the transfer process of respiratory infectious disease patient, and the sneeze of patient, cough can carry a large amount of virus, and under the condition of not having perfect tertiary protective equipment, medical staff and other uninfected personnel are infected very high risk, and the droplet that the patient speaks mixes in the air, forms aerosol, or the droplet deposits on the surface of article, easily causes other uninfected personnel to contact the virus and consequently leads to the infection.
