Abstract
A pressure reduction mattress construction for a liquid or gel bed having a flexible basin (10) forming a cavity (20) with inclines head (16H) and foot (16F) for surrounding and supporting a liquid or gel filled flotation bladder (30) that is anchored (36) to the head of the basin (10). The inclines (16F & 16H) made of a soft yielding material allow the head or foot of the bed to be easily raised as the liquid or gel (48) moves toward the center of bed. The head incline (16H) also serves to provide a soft yielding surface to support a patient after liquid or gel (48) has naturally moved to the sacral area (21). The entire structure is then covered with a flexible and yielding hospital fabric cover (40), giving the bed the appearance of a conventional hospital mattress. In some disclosed embodiments, an optional heater pad (22) may be used with a fiber (25) filled sacral bladder (26) placed over the heater pad (22) to prevent complete displacement of water over heater pad (22). In other embodiments a sacral bladder (26) is used to provide extra support when sitting up.
