ABSTRACT:
For monitoring body movements of a patient on a support, particularly to ascertain risk of bed sores, at least one fluid filled cell is inserted between the patient and a support on which the patient is lying. There is a detector of fluctuations in the state of the fluid in the cell caused by body movements of the patient, providing an output dependent on the fluctuations. This output is analysed by discriminating between fluctuations which are indicative of major body movements and fluctuations which are indicative of minor body movements.
