  • Patent number: 8122545
    Abstract: A cushioning device for a body support such as a mattress, seat, sofa, or the like where support is obtained from a fluid. The cushioning device is self-inflating, self-adjusting, and provides a low interface pressure under the entire contact surface of a patient. Shear force scraping damage is prevented by a sleeve apparatus. A support system apparatus provides separately adjustable pressure support zones. For physical therapy, an alternating pressure system provides alternating lifting and lowering pressure zones under a patient.

  • Patent number: 8087113
    Abstract: An alternating pad comprises a first set and a second set of alternately inflatable cells. Both sets of inflatable cells are supplied with air from a pump via a rotary valve. A sensor is positioned under the pad to receive pressure exerted by a patient upon movement and to be compressible relative to the applied pressure. Any change in patient position or movement will cause an alteration in the airflow in the sensor pad tube and will reduce or increase the differential pressure measured at the pressure transducer. Based on this feedback the microprocessor directly controls the power level to the pump and increases or decreases the air flow to the cells to alter the amplitude of the cells and also controls the timing of the rotary valve to change the timing of the inflation and deflation cycle.

A pressure controller controls the output of the compressor. Also connected to supply line (3) is an angle detection valve (40) restricting flow of air to atmosphere with increase in its angular position and a pressure transducer (17). Any increase in pressure due to an increase in angle of the detection valve (19) results in back pressure in the detection line. The pressure controller (2) uses the pressure transducer (17) to detect this change in pressure and then acts to adjust compressor output to the cells (9, 10) accordingly. The angle detection valve (40) is positioned under the head section of the pad to move with the head rest section.

  • Publication number: 20110138539
    Abstract: A method for adjusting pressure within an air bed comprises providing an air bed that includes an air chamber and a pump having a pump housing, selecting a desired pressure setpoint for the air chamber, calculating a pressure target, adjusting pressure within the air chamber until a pressure within the pump housing is substantially equal to the pressure target, determining an actual chamber pressure within the air chamber, and comparing the actual chamber pressure to the desired pressure set-point to determine an adjustment factor error. The pressure target may be calculated based upon the desired pressure setpoint and a pressure adjustment factor. Furthermore, the pressure adjustment factor may be modified based upon the adjustment factor error determined by comparing the actual chamber pressure to the desired pressure setpoint.

  • Patent number: 7954186
    Abstract: A cushioning device having a first deep cell inflatable bladder, a first restraint structure, a pump and an attachment. The first deep cell inflatable bladder has a first side, a second side, an upper surface and a lower surface. The first restraint structure has a top surface and a bottom surface. The pump has (a) a maximum inflation mode that inflates the first deep cell inflatable bladder so the bladder's upper surface and the first restraint's top surface are in or approximately in the same plane and (b) a normal operating inflation mode that provides sufficient inflation to (A) prevent the first bladder's upper surface from contacting the first bladder's lower surface, (B) decrease (i) the formation of debuticus ulcers on a patient and (ii) the patient's tissue interface pressure, and (C) allow the restraint structure to inhibit and/or restrain the patient from rolling off the first deep cell inflatable bladder.

  • Publication number: 20110094040
    Abstract: A system and method for controlling the flow of fluid for an inflatable body support 30 system, such as a mattress, having multiple, inflatable chambers. Each inflatable chamber can be selectively and independently inflated and deflated to vary the pressure exerted from the mattress surface to selected areas of a human body, thereby preventing the formation of decubitus ulcers. The system includes a valve assembly that includes a plurality of solenoid valves to direct air at a pressure of less than 1 pound per square inch into each chamber and a separate vent valve all operable by a controller to regulate the level of inflation of each inflatable chamber.

  • Publication number: 20110068932
    Abstract: A mattress system includes a mattress, a control unit spaced from the mattress, and a connector assembly that pneumatically and electrically interconnects the control unit with the mattress. The control unit has a main housing and a plurality of user interface modules that are selectively coupleable to the control unit and that are programmed differently to provide different modes of operation for the mattress system. A pressure sensor inside the mattress detects the presence or absence of a person on the mattress. The mattress system has a bed exit alarm system that, when armed, provides a bed exit alarm if the pressure sensor in the mattress detects that a patient has exited the mattress. The connector assembly includes a dual mode connector having both electrical and pneumatic couplers and a dual lumen hose assembly that extends from the dual mode connector to the mattress.
