The new coronaries are mainly characterized by fever, hypodynamia and dry cough, and severe patients rapidly progress to acute respiratory distress syndrome, sepsis shock, metabolic acidosis which is difficult to correct and coagulation dysfunction. Nasal high flow oxygen therapy has unique advantages in improving hypoxia symptom of patients and carrying out effective respiratory support, and reduces the death rate. At present, the clinical nasal high flow oxygen therapy is to supply oxygen through a disposable nasal oxygen tube; but bioaerosols are easily produced. When the old bedridden patient is in the supine position, the old bedridden patient is used to open the mouth and breathe, so that the lower jaw is opened; is unfavorable for oxygen inhalation and affects the oxygen therapy effect. While conventional oxygen inhalation devices have the following drawbacks in use: 1. the common oxygen inhalation mask has no pressure reducing device, and the edge is hard, so that the skin of the pressed part of a long-term wearer is easy to break. 2. The design of the opening of the nasal indwelling catheter is not adopted in all kinds of oxygen masks. While most of the old bedridden patients are left with nasogastric tubes and naso-intestinal tubes to improve the nutritional status or to perform gastrointestinal decompression to relieve the abdominal signs. Therefore, in the use of the current oxygen mask, the mask is generally worn on the mouth and nose of a patient directly, the edge of the mask is extremely easy to squeeze various nasal drainage tubes on the face of the patient, the skin at the tube placement position of the guide tube is damaged, and meanwhile, the mask cannot be completely attached to the face of the patient, so that the oxygen therapy effect is affected.
