Decubitus Prevention System Based on Mechanical Switches and Temperature Sensors
Bedsores (also known as Decubitus) are the adverse effects and emerge when skin under long-time pressured (including bones, and joints). The skin will cause poor blood loop so that cells cannot obtained nutrient, eventually cause injury to skin tissue. Unfortunately we will currently find that we are vulnerable to it. Bedsores have always been a threat to handicapped, illness or elderly persons who stays in bed or wheelchair for hours. Although normal human body is not threatened by bedsore, but there is no guarantee that any one of us can stay healthy forever. The price of existing medical instruments designed for bedsores are costly. Therefore we use mechanical switches and temperature sensors which are much cheaper to measure local pressure and temperature of body parts. The blood circulation of certain parts of the body can be monitored to solve bad blood circulation problem caused by local overpressure.
