Title:
CONFIGURABLE AIR DIFFUSION BODY SUPPORTS
Document Type and Number:
WIPO Patent Application WO/2015/021374
Kind Code:
A4
Abstract:
A patient positioning wedge, mattress, pillow, pod, or other surface or apparatus for preventing or relieving pressure ulcers or other types of wounds through low air loss therapy, alternating pressure therapy, or both, and the ports, controllers, and manifolds used in combination. The mattress includes a plurality of perforated or otherwise porous air cells for supporting the patient's body weight. The mattress further includes valves and accessory ports to pump air into accessories, such as patient positioning wedges, pods, and pillows. Each accessory also includes perforated or otherwise porous air cells. The air cells in the mattress and accessories allow for low air loss therapy and/or alternating pressure therapy by passing air between the contact surface of the mattress or accessory and the contact surface of the patient, thus helping alleviate pressure, heat, friction, and moisture, while maintaining support and stability of the patient.
