    摘要： A rotary valve for use in controlling an air supply to an inflatable patient support system, especially an alternating pressure mattress. The rotary valve comprises a body member having a planar surface and at least two apertures for communication with cells or sets of cells in the patient support system. A further aperture is provided for connection to a pressurized air source and an actuator member is rotatable in face to face contact with the planar surface. The actuator has a recessed portion which forms an air supply chamber when in contact with the planar surface. The valve further comprises a drive for rotating the actuator with respect to the first member and a detector for detecting the position of the actuator relative to the body member and, in conjunction with a control for controlling the timing and duration of air supply to the cells or sets of cells.

    摘要： An alternating pressure pad comprises at least two sets of inflatable cells, an air supply line to each set, a pump to circulate pressurized air through a circuit including the sets of cells and to return air from the cells to the pump, valve means for alternately causing inflation and deflation of each set, a sensor pad in the circuit through which pressurized air is passed and detecting means for detecting a reduction in air flow through the sensor pad to a level below a predetermined level and for increasing air pressure in the sets of cells to restore the air flow to a level above the predetermined level.
