Description

A high-flow oxygen inhalation combined device for preventing the generation of biological aerosols

technical field

The invention relates to the field of breathing apparatus, in particular to a high-flow oxygen-absorbing combined device for preventing the generation of biological aerosols.

Background technique

New coronary pneumonia is mainly manifested as fever, fatigue, and dry cough. In severe cases, it rapidly progresses to acute respiratory distress syndrome, septic shock, metabolic acidosis that is difficult to correct, and coagulation dysfunction. Nasal high-flow oxygen therapy has unique advantages in improving patients' hypoxic symptoms, providing effective respiratory support, and reducing mortality. At present, the clinical use of nasal high-flow oxygen therapy is a disposable nasal oxygen tube to give oxygen; but it is easy to generate biological aerosols. When the elderly bedridden patients are in the supine position, they are used to mouth breathing, which causes the jaw to open; it is not conducive to oxygen inhalation and affects the effect of oxygen therapy. The conventional oxygen inhalation device has the following defects in use: 1. The ordinary oxygen inhalation mask does not have a decompression device, and the edge texture is hard, and the skin of the pressure part of the long-term wearer is easily damaged. 2. There is no opening design for nasal indwelling catheters in all types of oxygen inhalation masks currently in clinical use. However, most elderly bedridden patients have indwelling nasogastric and nasoenteric tubes to improve nutritional status or perform gastrointestinal decompression to relieve abdominal signs. Therefore, in the current use of oxygen masks, the mask is generally worn directly on the patient's mouth and nose, which can easily cause the edge of the mask to squeeze various nasal drainage tubes on the patient's face, causing damage to the skin where the catheter is placed. It also cannot completely fit the patient's face, which affects the effect of oxygen therapy. 3. For the elderly patients treated in the new crown, it is necessary to atomize and inhale phlegm-relieving drugs to help the sputum discharge. However, the currently used atomizing inhaler is not compatible with the high-flow oxygen nasal cannula, and the oxygen nasal cannula needs to be removed to replace the nebulizer. Repeated pulling can easily cause skin damage and increase the workload to a certain extent.
