Background

When a patient with weak lung function and dyspnea is treated, oxygen supply equipment is usually used for supplying oxygen to the patient, so that the patient is prevented from being seriously ill due to the dyspnea. In the case of different altitudes, the oxygen pressure to be supplied is different, so that the medical staff needs to adjust the oxygen supply pressure of the oxygen supply equipment when reaching different altitudes. Or the same oxygen supply equipment, when each oxygen supply equipment arrives at areas with different altitudes, local medical personnel need to adjust the oxygen supply pressure of the equipment. However, the experience and skill of the worker are important to adjust the oxygen supply pressure, and thus the results of the adjustment are different among different persons. And once medical personnel forget to adjust the oxygen supply pressure, the treatment of the patient is seriously influenced. And along with the change of the altitude, medical staff can not adjust the output pressure of the oxygen supply device at any time, and for the areas which do not need to adjust the pressure at ordinary times, the medical staff in the areas can not adjust the output pressure of the oxygen supply device once the medical staff enters the high altitude areas.

And the oxygen supply amount of different altitudes is different, the adjustment of the oxygen supply mode is easier, only medical staff are needed to adjust the equipment, but the adjustment precision of the oxygen supply amount is not high, and the adjustment method basically depends on the experience and proficiency of the medical staff. And doctors often have no time to count and regulate the oxygen supply of patients along with the change of the illness state of the patients. In different altitude areas, if the oxygen supply quantity does not meet the requirement, the treatment of the patient is influenced non-negligibly.

Meanwhile, people entering the plateau area are prone to discomfort caused by the problem of low oxygen content in the air, and even more serious conditions occur, so that the people need to be supplied with oxygen independently, and the people gradually adapt to the plateau area or an anoxic environment to ensure the respiratory safety of the people. At present, oxygen supply to people of this kind needs to pass through a single oxygen supply device, and an oxygen bottle for supplying oxygen can be used for many times, but the mask for supplying oxygen needs to be additionally treated after being recycled, so the recycling cost is higher, and the direct discarding can cause waste. And when controlling the oxygen supply volume, a lot of users do not know how to adjust the oxygen supply volume to reach the purpose of reducing the oxygen waste, and the oxygen supply volume that different altitude areas need is also different, therefore to same kind of product, the user still uses the same oxygen supply volume at different altitude, thereby has caused the waste of oxygen, or because the not enough demand that can't satisfy the user of oxygen supply volume.
