[0002] Critically ill patients have extremely high requirements for oxygen during transportation, but MRI examinations cannot be performed with transport ventilators or oxygen cylinders, only oxygen bags. Currently, the common method is to use transport ventilators or oxygen cylinders before and after transporting patients for MRI, and use oxygen bags after entering the examination room.

[0003] Oxygen bags have a disadvantage. Once a certain amount of oxygen is output from the bag, the internal pressure will gradually decrease.

[0004] 1. Ordinary oxygen bags are difficult to meet the needs of critically ill patients for MRI in clinical applications: the oxygen flow is unstable, the oxygen therapy effect cannot be achieved, resulting in low pulse oxygen and even interruption of examination;

[0005] 2. Relying on manual labor to squeeze the oxygen bag to supply oxygen. Most of the time, it is difficult for medical staff to allocate manpower to supply oxygen: the patient's body gravity, the patient's family members squeeze;
