A pad () of interleaving linear cells () has loop straps () to hold the central section of the cells () linearly in parallel with the cell axis (), whilst the opposite ends () of each cell () are secured a pre-determined distance () off-set from the cell axis (). The distance () can vary along the length of the pad. By fixing of the ends () of the cells () at a distance () away from the cell axis, each end () of the cell () is pulled away from the centre axis of the cell, the loop straps () and the cell () become tensioned, preventing the central cell section from moving or rotating. The resulting cell has been seen to dramatically reduce the movement of a user along the pad with improved user comfort and enhanced pressure relief.

Inflatable pad

An alternating pad consisting of transverse inflatable cells (and) alternately inflated and deflated. An internal cell () is provided at the outermost edges of each transverse cell (). The internal cell () is constantly inflated at a higher pressure than the traverse cells (). The internal cell () is at a lower height than the cells () and preferably of a chamfered shape to provide optimum pressure relief across the whole surface of the pad. The internal cell () provides stable patient exit, entry or transfer from a bed or seat.

Inflatable support

A pressure pad has two sets of cells with a sensor pad positioned under the pad. During inflation, part of the flow goes to the sensor pad to exhaust and the rest fills the cells. Any change in patient position/weight causing a change in airflow in tube will alter the differential pressure measured at a pressure transducer. Based on this feedback a microprocessor directly controls the power level to the pump, thus adjusting the airflow to the cells to prevent bottoming or to rung at a minimum pressure. The pressure pad is segmented into a heel section, upper leg section, torso section, and a head section. The heel, head, and upper leg sections are maintained at a lower pressure, and the torso section at a higher pressure. A control module to control the flow in the segments is provided inside the pressure pad. The pressure pad can be an alternating or static pad.

Seat cushion

Alternating pad

A patient support includes an alternating pressure pad having separate sets of alternately inflatable cells and at least one further inflatable cell under the pad, with a support for the head of a patient lying thereon, and a control mechanism arranged to maintain alternate inflation and deflation of the cells of the pad to deflate the cells at the head end of the pad and also to inflate the cells under the pad in order to raise the level of the chest of a patient supported on the pad.
