PURAP is developed by PRS Medical Technologies, Inc. (“PRS”), a privately-held company engaged in the development, manufacture, and commercialization of medical devices to prevent and expedite treatment of pressure ulcers/sores, also known as decubitus ulcers. PRS’s technology applies laws of physics to minimize focalized peak skin interface pressures at or near bony prominences that are typically associated with formation and existence of pressure ulcers. PRS strives to improve people’s lives through easy to use products based upon patent pending technologies that enable low cost alternatives to complicated and expensive products that are less effective than PRS products in lowering peak skin interface pressures. PURAP is a FDA registered product.
PRS was founded in 2011 to develop technologies that minimize peak skin interface pressures of products that are in direct contact with people. PRS believes that the lowest peak skin interface pressures will result in lowest rates of pressure ulcers.
