Patients in severe rehabilitation are often in long-term bed rest, and a series of complications (bedsores, muscular atrophy, decline in cardiopulmonary function) are key factors seriously harming the life and health of the patients. Therefore, the medicine has great clinical significance for the early rehabilitation treatment of severe patients lying in bed for a long time. Research shows that the rehabilitation therapy aiming at the severe patients can obviously improve the cardio-pulmonary function and reduce the incidence rate of the limb muscular atrophy. The electric standing bed is an important medical instrument for helping a critically ill patient to realize early rehabilitation, can help a long-term bedridden patient to realize weight-losing standing training from a flat lying position to an upright position and lower limb passive exercise training, and can effectively relieve the muscular atrophy symptom of the limb of the patient and improve the cardio-pulmonary function.
