Abstract
Support pads for reducing the pressure exerted on some portion of the human body are disclosed. A first transparent flexible plastic sheet is bonded to a layer of four-way stretchable polyamide fabric which houses a medical-grade gel. An external surface of the four-way stretchable fabric is coated with urethane to avoid migration of the enclosed gel. This support pad exerts a pressure that is below the level producing venous stasis (0.5 psi).
Claims4
A pad for supporting at least a portion of a human body while a patient lies substantially motionless for a prolonged period of time, said pad producing a contact pressure of less than 0.495 psi and comprising:
- a) a compartment having at least a first body-contacting surface made of a four-way stretchable fabric having elastane fibers incorporated therein;
- b) a medical-grade gel contained within said compartment;
- whereby said medical-grade gel and said four-way stretchable fabric synergistically combine to provide a support for the portion of the body while laying substantially motionless which exerts a pressure of less than 0.495 psi, below that which causes venous stasis.
