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: An occupant support includes a turn assist layer which includes left and right side arrays of two or more longitudinally distributed turn assist members. Each array member comprises one or more longitudinally distributed turn assist bladders. At least two of the array members on the left side are longitudinally spaced from each other by a left intermember reach-in space having a left intermember dimension. At least two of the array members on the right side are longitudinally spaced from each other by a right intermember reach-in space having a right intermember dimension. A support layer resides above the turn assist layer. The support layer includes a collapsible zone at least part of which overlies the intermember spaces. The occupant support also includes a user interface for enabling a user to operate the turn assist layer.

Abstract: A control system of a patient support surface calculates a surface performance index as a function of pressure and shear. The control system also receives information from an electronic medical record (EMR) corresponding to a person's susceptibility of developing at least one of a pressure ulcer and a superficial lesion and adjusts at least one of a component and a characteristic of the person support surface based on the information.

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 method and a system have been described to determine a pressure relief set point for a person-support apparatus. The method includes determining the change in pressure or volume in a zone from a vacant mode to a person occupied mode and computing the weight supported there from.

Abstract: A patient support apparatus includes a pressurized air source, a dehumidifier, and a support surface including a topper having a vapor-permeable surface.

Abstract: A person-support surface comprises a non powered mattress and a coverlet positionable on the non powered mattress. The coverlet includes an entry positioned at a first end of the coverlet, an exit positioned at a second end of the coverlet opposite the entry, an upper air impermeable layer, and a lower air impermeable layer coupled to the upper air impermeable layer to form an air flow path along the coverlet between the entry and the exit. The upper air impermeable layer is a vapor permeable and the lower air impermeable layer is a vapor permeable.

Abstract: Systems, methods, and devices for optimizing a level of fluidization of a fluidizable medium in a fluidized person support apparatus.

Abstract: A patient support includes a cover defining an interior region, an air permeable first layer located in the interior region, and a first air supply coupled to the first layer to provide air flow through the first layer. The patient support also includes a plurality of air bladders located beneath the air permeable first layer and a second air supply coupled to the air bladders to selectively inflate and deflate the air bladders. An angle sensor is located in the interior region in an articulatable portion of the patient support. A controller is coupled to the first and second air supplies and the angle sensor to control inflation and deflation of the air bladders in response to an angle signal received from the angle sensor and to control air flow through the air permeable layer in response to the angle signal.

Abstract: A method of accommodating pressure ulcer vulnerability of an occupant of an occupant support, a method of managing pressure ulcer risk of an occupant of an occupant support, and an occupant support adapted to manage pressure ulcer risk of an occupant thereof are disclosed. The methods and occupant support account for occupant specific or occupant class specific risk factors based on empirical data.

Abstract: A person-support surface comprises a non powered mattress and a coverlet positionable on the non powered mattress. The coverlet includes an entry positioned at a first end of the coverlet, an exit positioned at a second end of the coverlet opposite the entry, an upper air impermeable layer, and a lower air impermeable layer coupled to the upper air impermeable layer to form an air flow path along the coverlet between the entry and the exit. The upper air impermeable layer is a vapor permeable and the lower air impermeable layer is a vapor permeable.

Abstract: A communication system for a patient support apparatus that is operable to inductively power sensors coupled to a patient to periodically gather data from the sensors. The communication system is operable to associate the sensor data with a patient and the patient support apparatus and transfer the associated data to a hospital information system.

Abstract: This disclosure describes a patient support having an air permeable layer, a plurality of inflatable bladders, a pressure-sensing assembly and a controller. In one embodiment, a combination of transverse bladders and vertically oriented can-shaped bladders is provided. In one embodiment, one or more angle sensors are provided in articulatable sections of the patient support.

Abstract: A patient support apparatus includes a pressurized air source, a dehumidifier, and a support surface including a topper having a vapor-permeable surface. The dehumidifier is configured to selectively treat pressurized air communicated to the dehumidifier from the pressurized air source and communicate the treated pressurized air to the vapor-permeable surface.
