Abstract
The present disclosure relates to a manually actuatable exhaust valve, coupled to an inflatable support surface that includes a position sensor that sends a signal to a controller indicating whether the manually actuatable exhaust valve is open or closed. In response to a signal indicating that the manually actuatable exhaust valve is open, the controller automatically shuts off a fluid source to the inflatable support surface.
Claims20
An inflatable support system comprising:
- an inflatable support structure configured to support a person;
- and
- a manually actuatable fluid exhaust valve configured to exhaust fluid from the inflatable support structure when the fluid exhaust valve is in an open position, comprising a housing having a manually movable portion that moves the exhaust fluid valve, and a valve state position sensor configured to detect at least an open valve position of the fluid exhaust valve in response to manual actuation of the movable portion of the housing and send a signal in response to an open position of the fluid exhaust valve indicating a deflation action and to detect a closed position of the exhaust valve indicating an inflation action for the inflatable support structure.
A support system comprising:
- a frame;
- an inflatable support structure supported by the frame;
- a fluid pump operatively coupled to provide fluid to the inflatable support structure;
- a manually actuatable fluid exhaust valve configured to exhaust fluid from the inflatable support structure when the fluid exhaust valve is in an open position, comprising a housing having a manually movable portion that moves the exhaust fluid valve, and a valve state position sensor configured to detect at least an open valve position of the fluid exhaust valve in response to manual actuation of the movable portion of the housing and send a signal in response to an open position of the fluid exhaust valve indicating a deflation action and to detect a closed position of the exhaust valve indicating an inflation action for the inflatable support structure;
- and
- a controller operatively coupled to the fluid pump and to the manually actuatable fluid exhaust valve, and operative to shut off the fluid pump, in response to the signal indicating the deflation action for the inflatable support structure and operative to start fluid supply to the inflatable support structure in response to a signal from the valve state position sensor indicating closure of the valve.

A fluid exhaust valve assembly comprising:
- an exhaust valve housing comprising a manually rotatable member and a fixed member, the fixed member configured to couple with a plurality of fluid tubes of an inflatable support structure, the manually rotatable member being rotatable relative to the fixed member about a rotation axis and having at least one fluid output port configured to release fluid from the plurality of fluid tubes in response to rotation of the rotary member causing an open valve position and the exhaust valve housing comprising a valve state position sensor operative to provide a signal in response to movement of the manually rotatable member indicating a an open valve position and deflation action for the inflatable support structure.
A method for controlling an inflatable support apparatus comprising:
- detecting, in response to a signal from a valve position sensor on a manually actuatable exhaust fluid valve that is configured to release substantially all fluid in the inflatable support apparatus, an open position of the exhaust fluid valve;
- shutting off a fluid pump coupled to provide fluid to the inflatable support apparatus, in response to the signal indicating the deflation action for the inflatable support apparatus;
- and
- starting fluid supply to the inflatable support apparatus in response to closure of the exhaust fluid valve.
