A support structure for a patient at risk of pressure ulcers comprises a first vibration motor 16 disposed within a housing, a first flexible sheet frame 12 connected to said housing, and a first layer of resiliently deformable plastics material foam 14 bonded to a first surface of said sheet frame 12. The support structure may be used with, or incorporated in, a mattress or cushion on which a patient lies or sits. The mattress or cushion may have pressure relief features such as a castellated surface or a pneumatically operated alternating pressure inflatable cells 42. The sheet frame 12 can be solid or a metal lattice and can have a hinge. The motor 16 may produce cycloidal vibrations and have control means to allow it to operate at specified intervals. A plurality of motors 16 and sheets 12 may be used and may be positioned near high risk areas of a mattress. The device is designed to help prevent pressure ulcers. |
