Pressure control of cellular electromechanical medical mattress for bedsore prevention

Pressure ulcers are a serious problem that affects more than one million patients worldwide each year. These ulcers often occur when patients have limited mobility and cannot change positions in bed on their own. Although there are guidelines for the care and transportation of high-risk patients and products for the care of these patients have been developed and marketed, the rate of pressure ulcers continues to rise. This paper presents a prototype control pressure ulcer platform. This system controls the standard threshold pressure level by receiving feedback from the patient and bed pressure status. The proposed system has been designed and implemented. Also, mechanical and electronic structures are modeled and, a suitable controller is designed for optimal performance. The performance of the system has been proven by simulations performed.
