Pressure reducing device

摘要

A pressure reducing device for reducing pressure at bony prominences of limbs is disclosed. A preferred embodiment is formed of an elastic foam, having upper and lower portions similar to oppositely-facing square pyramids, but having four arced sides rather than flat sides, and where the four sides converge at their apexes to form a blunted peak. The cushion body is shaped and sized so as to reduce the loading and shearing forces over the bony prominences of limbs, thereby reducing pressure and to readily allow a user to move along the support surface and to change orientations (roll or lie on their side).

主权项

1. A foam limb-support device for reducing pressure on heels and feet and other bony prominences for a user, comprising:
an upper portion and a lower portion which are each shaped as oppositely-facing square pyramids having four converging arced sides; a channel extending through the device between the upper portion and the lower portion; and wherein, at least one of the upper portion and lower portion includes a separation running the length of the channel and dividing at least one said portion into two parts, such that when the two parts are separated, a user's limb can pass between the two parts and into the channel; and a means for fastening said two parts together, once the user's limb is in place in the channel.
