A pressure sore (also called pressure ulcers or bedsores) is any redness or break in the skin caused by too much pressure on your skin for too long a period of time. Pressure sores are localized areas of cellular necrosis that occur most often in the skin and subcutaneous (SC) tissue over bony prominences. These ulcers may be superficial, caused by localized skin irritation with subsequent surface maceration, or deep, originating in the underlying tissue. Deep lesions often go undetected until they penetrate the skin, but by then they have usually caused subcutaneousdamage. Unrelieved pressure on the skin squeezes tiny blood vessels, which supply the skin with nutrients and oxygen. When skin is starved of nutrients and oxygen for too long, the tissue dies and a pressure ulcer forms. Skin reddening that disappears after pressure is removed is normal and not a pressure ulcer. Prevention systems seem to be essential, especially in hospitals. Mechanized and manual bed design for use by inactive patients in the hospital and at home. This bed is fitted with a heating system to keep the patient warm in winter and cooling system in summer. The function of this device is as follows: The patient is resting on the bed and depending on the specific timing the patient turns left and right. It is also equipped with a massage sensor to also massage the specific areas of the patients body.
