[0002] Atrophy of the body function of patients who have been in bed for a long time is an important problem. The body of the patient who has been in bed for a long time is pressed for a long time, which can easily affect blood circulation and cause pressure sores. The inflatable local lifting mechanism can change the contact points between the patient's body and the bed surface by inflating different parts, disperse the pressure, reduce the risk of pressure sores, and appropriately lift the local part to make the pressed part intermittent relaxation, which is beneficial to blood circulation, provides sufficient oxygen and nutrients for tissues, speeds up the excretion of metabolic products, and reduces tissue damage. When medical staff lift the limbs of the patient, the existing local lifting device for the limbs of the bedridden patient is not convenient for the medical staff to adjust and move, which wastes the working time of the medical staff and brings great inconvenience to the medical staff. Some rehabilitation training requires the patient to be in a specific angle, such as leg rehabilitation training, which requires the leg to be appropriately lifted and the angle to be adjusted to promote blood circulation and muscle recovery.
