    Decubitus ulcer or bedsore is a pressure-induced ulceration of the skin occurring in persons confined to bed for long periods of time. Reduction of pressure over bony prominences is of primary important to prevent and cure bedsore. For this purpose, specially designed air mattresses are commonly used. However, in backrest motion of a normal medical bed with the air mattress the patient is pushed and slides down along the bed because of its thickness. New medical bed mechanism needs to prevent this sliding between the patient and the bed. The synthesis of a mechanism that prevents this motion, however, is very difficult and takes time. In this study, parameters related to the motion of the backrest are determined by sensitivity analysis. Using adjustable linkage to the previous bed mechanism we perform kinematic synthesis of a medical bed which minimizes the sliding whether in the case of the normal mattress and the air mattress.
