Background

The three influenza pandemics in 1918, 1957 and 1968 of the 20 th century caused millions of deaths, the major cause of death being acute respiratory failure. In recent decades, severe acute respiratory syndrome coronavirus (SARS) was outbreaks in 2002 and middle east respiratory syndrome coronavirus (MERS) was outbreaks in 2012, characterized by interpersonal spread and extremely high incidence of acute respiratory failure. And the recent 2019-nCoV also draws an alarm all over the world, and the key for saving critical patients and obtaining anti-epidemic victory is to effectively control the transmission, effectively carry out oxygen therapy on the respiratory failure patients and support the respiration.

Pure oxygen therapy and non-invasive ventilation are effective and common therapies to rescue patients with mild to moderate acute respiratory failure. With the support of multiple random trials, oxygen therapy and non-invasive ventilation can significantly reduce the mortality rate of patients with respiratory failure compared to pure drug therapy and mechanical ventilation by endotracheal intubation. The emergency department and intensive care unit nursing units increasingly adopt noninvasive ventilation, and the clinical treatment effects of noninvasive respiration and oxygen therapy are fully verified. However, in the face of large-scale and severe infectious diseases, the shortage of medical staff and the exposure risk of the medical staff in the treatment of patients are examined for the existing artificial modes of pure oxygen therapy and noninvasive ventilation. There is an urgent need for a device capable of remotely monitoring the blood oxygen saturation, heartbeat, respiration, blood pressure, body temperature and mental condition of a large number of patients in real time outside an isolation ward, timely feeding back the oxygen therapy or non-invasive ventilation therapy effect of the patients, and automatically adjusting and remotely controlling the simple oxygen therapy (oxygen therapy time, oxygen flow and the like) or the non-invasive ventilation (whether the mask of the patients leaks air, the non-invasive ventilator mode, the inspiratory pressure and the expiratory pressure are proper and the like).

In addition, aerosols are an important mode of transmission, and during wearing of the respirator, a large amount of aerosols may be generated, resulting in extremely dangerous viral exposure to medical personnel. Therefore, there is also a need for a device that assists a patient in donning, doffing, and cleaning a respiratory mask that actually assists the patient in the treatment of respiratory failure and in cutting off doctor-patient dissemination.

It can be seen from the current pandemic diseases that the respiratory failure support treatment is remotely and intelligently realized, the medical care occupational exposure is reduced, and the method plays an important role in the current disease treatment, control and future protection.
