-
Bed mattresses filled with gel to provide a pressure-relief surface to the patient. These mattresses are typically made of a foundation (e.g., foam) with several sections of gel bladders. Gel mattresses are used to reduce the pressure delivered from the mattress surface to the patient\'s skin (e.g., for the prevention of pressure sores [decubitus ulcers]).
-
Cushioning pads designed to reduce pressure on specific areas or the whole body that are filled with gel. These pads consist of a sealed plastic (e.g., vinyl) enclosure filled with liquid gel; the enclosure may include several interconnected sections that allow the movement of the gel when pressure is applied. Dedicated gel-filled pressure relief pads may be conformed in a variety of shapes and sizes. They are mainly used to distribute localized pressure to larger body areas or to shift the body weight to a different position, especially to prevent or alleviate pressure sores. Gel-filled pads are frequently used on top of chairs, wheelchairs, tables, and beds.
