摘要： One embodiment of a topper assembly for a mattress comprises a liquid permeable cover layer, a liquid transport layer beneath the cover layer that directs liquid transport therethrough in a preferred direction, a liquid impermeable base layer beneath the transport layer, an air mover in fluid communication with the transport layer and a reservoir positioned downstream of the liquid transport layer. Operation of the air mover moves air and liquid through the liquid transport layer in the preferred direction such that the reservoir captures liquid discharged from the liquid transport layer. A related support apparatus comprises a mattress and a condition management assembly atop the mattress. The condition management assembly includes the liquid transport layer, the liquid impermeable base layer, the air mover and the reservoir.

摘要： A method for detecting occupant position change on a support surface includes establishing a rate of change of pressure in a head end test zone and in a foot end test zone, comparing the head end rate to at least one head end rate limit, comparing the foot end rate to at least one foot end rate limit, and inferring, in response to the comparing steps, whether or not occupant migration has occurred. An associated occupant support includes a frame and a mattress. The mattress includes head and foot zones each having at least one pressurizable bladder. The support also includes a controller adapted to compare a head end rate of pressure change to a head end rate limit, to compare a foot end rate of pressure change to a foot end rate limit, and to infer, in response to the comparing steps, whether or not occupant migration has occurred.

摘要： A method for controlling performance of an MCM capable support surface having a flowpath for guiding a stream of air along at least a portion of the surface, comprises specifying a desired evaporative rate greater than an evaporative rate achievable with unconditioned ambient air, chilling the unconditioned ambient air to a temperature at least as low as that required to achieve 100% relative humidity, thereby demoisturizing the air, and supplying the chilled, demoisturized air to the flowpath. The method may also include the step of heating the chilled, demoisturized air prior to step of supplying it to the flowpath. A system for carrying out the method includes a microclimate management (MCM) capable support surface 22, a chiller 60 for cooling air to be delivered to the MCM capable surface, a user interface 42 for receiving instructions concerning desired microclimate management performance, and a controller 50, responsive to the instructions, for operating the chiller.

摘要： A cooling system for an occupant of an occupant support comprises a coolant conduit having an inlet for receiving coolant and an outlet for discharging the coolant to a destination. The conduit is nonpermanently and manually shape adjustable, shape stable subsequent to adjustment, and removably securable to the occupant support, the occupant or both. In one embodiment the destination is an ambient environment selected to achieve targeted coolant delivery to a localized region of the occupant's body. A cooling glove to be worn by a user has at least one coolant intake and at least one of a) a coolant passage extending from the coolant intake to an exhaust opening which exhausts coolant to an ambient environment; and b) a cooperative relationship with the user which defines a fluid pathway bounded in part by the glove and in part by the user and which discharges coolant to an ambient environment.

摘要： A bed comprises a frame 34 with at least one orientation adjustable section (44, 46, 48), a mattress 58 supported by the frame and having at least one A bladder and at least one B bladder. The bladders are inflatable and deflatable out of phase with each other in coordination with at least one of a) issuance of a command for the frame section to change orientation and b) an actual change in orientation of the frame section. Also described is an associated method for operating an occupant support at least part of which is orientation adjustable relative to other parts of the occupant support. The method comprises providing, in response to a change of orientation of the orientation adjustable part, a relatively lower occupant/support interface pressure (OSIP) at a location A and a relatively higher OSIP at a location B followed by providing a relatively higher OSIP at the location A and a relatively lower OSIP at the location B.
