The invention discloses an intensive care restraint device and a use method. The device comprises a sleeve; the lantern ring is fixed outside the sleeve; the annular air bag is fixed in the sleeve; the bandage penetrates through a gap between the inner side of the lantern ring and the outer side of the sleeve; the connecting pipe is fixed on the surface of the sleeve; the air leakage assembly communicates with the surface of the connecting pipe. Through the arrangement of the built-in annular air bag, the annular air bag can uniformly wrap and be attached to the limbs of a patient after being inflated, concentrated binding force of a traditional binding band or a rigid structure is converted into uniform surface pressure provided by the annular air bag, the risk of skin bruise and nerve and blood vessel injury is reduced, the comfort of the patient is improved, the air bag can be conveniently inflated through the inflating assembly, and the air bag is convenient to use. The restraint tightness is accurately adjusted, the restraint effect is ensured to be reliable, quick deflation can be achieved through the deflation assembly, restraint loosening or adjustment can be conveniently and emergently achieved, the overall structural design is reasonable, operation is easy and convenient, and restraint effectiveness, patient safety and clinical nursing convenience are all considered.

The application belongs to the technical field of automobile air suspension and discloses an air supply unit control system and method, which comprises an electric control module, a valve body air path module, an electric drive module and an air drying module. The valve body air path module is provided with a winding heating regeneration air path, which can guide the high-pressure gas in the gas storage tank to flow through the motor winding for heating and then be introduced into the low-pressure cavity for the dryer regeneration. The electric control module realizes the intelligent operation of the system by executing a regeneration control algorithm, a pressure regulation strategy and a temperature-pressure collaborative control method. The regeneration control algorithm automatically triggers the regeneration process according to the humidity state or the time interval; the pressure regulation strategy maintains the stable system pressure according to the sensor signals; and the temperature-pressure collaborative control dynamically optimizes the control parameters according to the winding temperature and the air path pressure. The system effectively integrates the motor waste heat utilization, the dryer regeneration and the accurate pressure regulation and control, and improves the overall energy efficiency and reliability.
