The action mechanism of IFN is mainly to induce a series of expressions which mainly take IFN stimulating genes to influence the regulation and control genes of the IFN by starting a tyrosine kinase-signal transducer and a transcription activator path to generate a plurality of proteins and enzymes which directly act on viruses, thereby achieving the aim of preventing the body from being infected by the viruses; in addition, IFN plays an important role in regulating innate immune response and activating adaptive immune response. Although the administration route of the interferon has various modes, including subcutaneous and intramuscular injection, aerosol inhalation and the like, the injection of the interferon can cause adverse reactions such as a transient flu-like symptom, bone marrow suppression, mental disorder and the like, and the aerosol inhalation can effectively avoid the adverse reactions and improve tolerance and compliance; IFN can be distributed and absorbed in the lung to take effect, and animal experiments prove that the curative effect of atomizing and inhaling the IFN is better than that of other antiviral drugs; therefore, IFN aerosol inhalation is a convenient and effective administration route for treating the novel coronavirus infection, and represents an important role in the treatment of the infectious diseases in theory and clinical effect.
However, most infectious diseases in the respiratory system are accompanied by cough, the inhalation of the medicine can induce the irritable cough of a patient, the cough can generate a large amount of highly infectious aerosol and spray, the existing inhalation device only has a simple buccal ventilation hole or a simple mask which is covered on the mouth and the nose of the patient, the simple mask is provided with an exhalation hole which is directly and completely communicated with the outside, in addition, the edge of the simple mask cannot be in sealed joint with the face of the patient, and a large amount of gaps exist. Thus, existing aerosol inhalation devices expose the healthcare worker who is instructing the patient to aerosol inhalation therapy completely to the patient's large volume of highly contagious aerosols and droplets resulting from coughing, which is a major feature of respiratory infections, and the risk of infection for healthcare workers is no less than the occupational exposure for endotracheal intubation unless the healthcare worker is equipped with higher levels of protection, such as positive pressure hoods.
