For example, the usage frequency of the gas at each oxygen supply concentration may be determined from the oxygen supply concentration record of each user in the history database, and each oxygen storage device may be set according to the usage frequency corresponding to each oxygen supply concentration, and the capacity of the oxygen storage device corresponding to the gas with a high usage frequency is larger than the capacity of the oxygen storage device corresponding to the gas with a low usage frequency, that is, the higher the usage frequency corresponding to the gas is, the larger the capacity of the oxygen storage device corresponding to the gas is.
Optionally, the at least two oxygen input ports may be disposed on the enclosure. Further alternatively, each oxygen inlet may be provided with a sliding cover matching its shape and size. The noninvasive ventilator can be specifically configured to open the sliding cover corresponding to the target oxygen input port by controlling when receiving the first control instruction, so as to supply oxygen to the user through the target oxygen input port. For example, the noninvasive ventilator includes three oxygen input ports, an oxygen input port 1, an oxygen input port 2, and an oxygen input port 3, each of which may be provided with a corresponding slide cover.
In some alternative embodiments, the opening sizes of different oxygen input ports may be set to be different, such as the opening of an oxygen input port with a high oxygen concentration is larger than the opening of an oxygen input port with a low oxygen concentration, and such as the opening of an oxygen input port with a specific oxygen concentration (such as an oxygen concentration suitable for emergency treatment or an oxygen concentration with the highest frequency of use, etc. counted according to historical data) is set to be the maximum, so as to quickly realize the gas with a high oxygen concentration (or a specific oxygen concentration) for the user in an emergency situation; and/or the opening shapes of the different oxygen input ports may be different. So that medical staff can quickly identify the oxygen concentration (oxygen supply concentration) currently used. For example, the oxygen inlet 1 and the oxygen inlet 2 have different shapes, and the three oxygen inlets have different sizes, such as a circular inlet of the oxygen inlet 1 having a diameter of 0.6 to 1.2cm (e.g., 0.7cm, 0.9cm, 1.1cm, etc.), an elliptical transverse diameter (longer diameter) of 2.8 to 3.4cm (e.g., 2.8cm, 3.1cm, 3.3cm, etc.) of the oxygen inlet 2, and a circular inlet of the oxygen inlet 3 having a diameter of 2.7 to 3.3cm (e.g., 2.7cm, 2.8cm, 3.2cm, etc.).
