Abstract:
A protective and pressure normalizing device including a support member having an exterior wall and an interior wall which define a first chamber and a second chamber, and a pressure adjustment device sealed within at least a portion of the second chamber, the pressure adjustment device defining a third chamber and a medium transfer passageway interconnecting the first chamber and third chamber.
Abstract:
A protective and pressure normalizing device including a support member (12) having an exterior wall (16) and an interior wall (18) which define a first chamber (20) and a second chamber (20a), and a pressure adjustment device (14) sealed within at least a portion of the second chamber (20a), the pressure adjustment device defining a third chamber (20b) and a medium transfer passageway interconnecting the first chamber and third chambers.
Abstract:
The present invention is directed to a gelastic cushion. The gelastic cushion is made from a conventional gelastic composition. The gelastic cushion has a structure having a first wall that defines an opening area and buckles when a force is applied to the first wall. When the first wall buckles a predetermined amount, a second wall, interconnected to the first wall, also buckles. The second wall decreases the chance that the first wall bottoms out. Bottoming out increases the pressure on the patient {a.k.a., the force) overlying the gelastic cushion. That increased pressure is undesirable.
