Abstract
A manually or automatically controlled adjusting bed-chair combination for persons suffering limited mobility due to accident, disease, or age who thus require intensive caregiving efforts by others. This portable body supporting device provides a patient with greater mobility and self-care even if he/she is confined therein for weeks, months, or longer. The bed-chair includes an upper frame for supporting the invalid'"'"'s body in a large number of postures ranging from side, supine, sitting, reclining or standing. In turn, this upper frame is articulated by lower supporting frames powered by linear actuators, or the equivalent, and controlled by the patient control or the caregiver'"'"'s override and automatically preset control to provide a timed regimen of turning or tilting according to the occupant'"'"'s needs. Whether in bed or chair mode, the support frame consists of an upper body, middle and leg-foot segment. The mid-section provides a base to which the other two sections are pivotally mounted. Turning the middle section up to 20° right or left relieves the local pressure on skin and other tissue yielding comfort and avoiding ulceration, cramping and discomfort. The optional accessories further increase the freedom of choice of more positions, actions, and controls, even to sensing difficulty and aiding excretion along with the option of using vibration and other therapeutic stimulations. The bed-chair'"'"'s diverse positions enable easier entrance and exit. Ready disassembly into three or more sections facilitates transport. A mattress with special foam distributes the body weight over maximum area while cervical and lumbar supports plus adjustable edge tubes give security and comfort choice to abet healing.
