Abstract: A bed comprises a mattress and a topper resting atop the mattress and extending in longitudinal and lateral directions. The topper has a fluid flowpath having an inlet and an outlet. The flowpath exhibits a nonuniform resistance to fluid flow in at least one of the longitudinal and lateral directions. The bed also includes a blower connected to the inlet for supplying air to the flowpath. The resistance may be a monotonically varying resistance to fluid flow in at least one of the longitudinal and lateral directions and configured to preferentially drive fluid flow through the topper so that a larger proportion of the fluid flowing through the topper flows under a target region and a relatively smaller portion bypasses the target region.

Abstract: 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.

Abstract: A patient support surface includes a cushion and an inflatable patient positioning unit. The cushion is adapted to support a patient. The inflatable patient positioning unit is arranged over a portion of a top side of the cushion at a foot end of the cushion. The inflatable patient positioning unit includes a plurality of positioner bladders shaped so that when inflated a distal end of each positioner bladder is taller than a proximal end of the positioner bladder.

The flowpath exhibits a nonuniform resistance to fluid flow in at least one of the longitudinal and lateral directions. The bed also includes a blower connected to the inlet for supplying air to the flowpath. The resistance may be a monotonically varying resistance to fluid flow in at least one of the longitudinal and lateral directions and configured to preferentially drive fluid flow through the topper so that a larger proportion of the fluid flowing through the topper flows under a target region and a relatively smaller portion bypasses the target region.

Abstract: A bed frame includes a weight bearing framework 30, and a footboard 82 that cooperates with the framework to define an edge 90 of an occupant region 92 of the bed. The footboard 82 includes a footboard frame 100 and a pressurizable cushion 104. A mattress system 160 includes a main occupant support portion 162 with a support surface 168 and a cushion 170 located footwardly of the occupant support portion. The cushion has a deployed state in which it projects vertically higher than the support surface and a stored state in which it does not project vertically higher than the support surface.

Abstract: 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.

Abstract: A topper (38) for a bed extends in longitudinal and lateral directions and includes a fluid flowpath (60) for channeling fluid through the topper from an inlet (62) to an outlet (64). The flowpath is configured to distribute the fluid to a preferred target region (50) of the topper. A bed which includes the topper has a blower (72) connected to the topper inlet for supplying air (88) to the flowpath.

Abstract: A patient position-activated room device control apparatus coupled to a patient's bed controls a device associated with a patient's room in response to the patient changing position relative to the patient's bed.

Abstract: A pneumatic accumulator integral to a structural member of a person-support apparatus to store air is disclosed. The accumulator serves as a reservoir available for rapid changes in demand for pressurized air, for use by a variety of devices integral or external to the person-support apparatus or for extension and retraction of at least one portion of the person-support apparatus. A pump supplies air to the accumulator. The pump and at least one pressure sensor are in communication with a controller. At least one valve in the fluidic path is in communication with the controller and meters the supply of air. The controller may further be connected with an alarming unit, hospital network, activity log, communication station nurse call system or electronic medical records.
