technical field

The invention relates to the field of medical technology, in particular to a respiratory medicine nursing mask capable of automatically controlling the concentration of oxygen inhalation.

Background technique

Nursing masks for respiratory medicine, also known as oxygen masks, are equipment that transfers oxygen from storage tanks to human lungs. Medical oxygen masks usually include ordinary masks, masks with storage bags, and venturi masks. Oxygen concentration should also be monitored in real time, to avoid the patient's breathing difficulties due to too low oxygen concentration, and the lack of nourishment effect. If the oxygen concentration is too high, the patient has been intoxicated with oxygen or oxygen poisoned.

Traditional oxygen masks generally need to manually set the oxygen concentration in the mask in advance. When the patient is breathing, there is a lack of real-time monitoring and adjustment of the oxygen concentration in the patient's inhaled air, which can easily lead to potential safety hazards.
