The Automatic Patient Turner is the ultimate in pressure sore prevention by automatically, periodically, and alternately tilting, and then laterally turning an immobile patient from one complete side to the other in a manner similar to, yet gentler and less intrusive than, manual turning. This is accomplished by the patterned, sequential inflation and deflation of six strategically-placed inflatables. When the bent knees (1) are perpendicular and sandwiched between a pair of inflated knee inflatables (6 and 7), they can serve as a lever arm in the turning process. When pressure is exerted against the bent knees (1), it causes them to move well beyond their perpendicular position. They then descend in the direction of the turn as the knee inflatables (6 and 7) deflate. The descending knees laterally pull the entire body of the patient completely to the side of the turn as a back-support pillow (8 or 9) inflates.

The invention relates to a medical care auxiliary appliance, in particular to bedsore-proof early warning device. The bedsore-proof early warning device is provided with a pressure sensitive element, a tissue hypoxia degree monitoring device, a data processing unit and an alarm unit. When in use, the pressure sensitive element is attached to a bedsore-susceptible part to monitor the pressure of the part, and the tissue hypoxia degree is monitored by an instrument, thereby the actual hypoxia degree of the tissue at the pressed part of a patient can be mastered in time. When the local tissue pressure of an individual exceeds a certain range and lasts for a certain time, and the oxygen partial pressure of the tissue is lowered and possible to cause ischemic hurt, the bedsore-proof warning device warns to prompt the medical personnel and caregiver to be on guard that the patient is in the risk of suffering bedsore and take measures in time such as turning over the body of the patient to prevent bedsore. The bedsore-proof early warning device greatly lowers the workload of the nursing personnel and reduces the pain of the seriously ill patients.
