摘要:
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.

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.

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.

A patient support apparatus includes a base, a frame coupled to the base, a deck supported by the frame and capable of moving relative to the frame, and a siderail assembly movable between a raised position above the deck and a first lowered position below the deck. The patient support apparatus further includes a siderail mover coupled to the deck to move the siderail assembly from the first lowered position to a second lowered position in response to movement of the deck relative to the frame.

A hospital bed has a base, an upper frame above the base, and a lift system to raise and lower the upper frame relative to the base between a low position and a high position. The bed also has control circuitry coupled to the lift system to command operation of the lift system. The control circuitry further includes an angle sensor to provide a signal indicative of an angle at which at least one of the base and the upper frame are tilted away from a substantially horizontal orientation. The control circuitry has an indicator that is activated to indicate to a caregiver that the lift system should be operated to move the upper frame to the low position when the angle sensor indicates that the angle is greater than a threshold amount.

One embodiment of a topper for a bed includes a liner assembly 40 having a top liner 42, a bottom liner 44 and a slip liner 70 underneath the bottom liner. The slip liner is of relatively lower friction than the top liner. An apron 62, with openings 76 therein, extends from the perimeter of the liners. Another embodiment includes a liner assembly having a top liner, a bottom liner and a slip liner underneath the bottom liner. The slip liner is of relatively lower friction than the top liner. Bridge straps 98, or 98′ having a working length of at least the width of a host mattress minus the arm length of a fifth percentile female extend from the liner assembly.

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.
摘要:
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.

A siderail assembly includes a guide, a support frame coupled to the frame and movable between first and second positions, and a barrier coupled to the support frame and movable therewith. The siderail assembly further includes a handle coupled to the barrier to move between a first position and a second position relative to the barrier. The siderail assembly may include electronic controls to change the position or limit movement of various portions of a patient support apparatus on which the siderail assembly may be coupled.
