Patent attributes
Technologies are provided for determining a likelihood or risk of a human patient for developing pressure injury based on patterns of movement by the patient determined using a specialized measurement support surface. Some embodiments automatically ascertain whether patterns of movements of a human subject, whose weight is supported on the support surface, exhibit sufficient frequency and variability of activity such as will confer either certain health benefits or expose the individual to certain health risks, such as development of pressure ulcers in the load-bearing skin and soft tissues. The measurement support surface can include a contact layer, a pressure-measuring layer having an air bladder subjacent to the measurement support surface, and a substrate layer with a density and stiffness to mechanically isolate the pressure-measuring layer from ambient vibrations transmitted through a floor, furniture, or other intervening articles upon which the measurement support surface is mounted.
