According to one embodiment, a seat cushion comprises a second air cell section that is located on the rear side of a seat surface and a third air cell section that is located rearward of the second air cell section. The second air cell section and the third air cell section are adjacent to each other and have a common boundary extending diagonally in the front-rear direction of the seat surface such that the ischial region of a user fits in the boundary.

A patient support, such as a mattress, includes a plurality of inflatable bladders. Depth sensors are included in the support that measure the degree of penetration of a patient into the mattress. An air pressure sensor is also included that measures the pressure inside at least one bladder. A suitable inflation level of the mattress is determined by monitoring the rate of change of the depth with respect to air pressure as the bladder is either inflated or deflated. By detecting an inflection point in the graphical relationship of the depth and pressure outputs, a suitable inflation point for the bladders is determined that reduces interface pressures experienced by the patient, yet does not overly sink the patient into the mattress to a degree of discomfort. Analyzing the outputs of the depth and pressure sensors can also be used to detect a patient's heart rate and respiration rate.

A patient support apparatus includes a first transceiver adapted to wirelessly communicate with a second transceiver of a headwall interface that is positioned off of the patient support apparatus. A communication link is automatically established between the first and second transceivers without requiring a user of the patient support apparatus to activate a designated control and without requiring the user to identify the headwall interface. The first transceiver includes a unique identifier assigned to the headwall interface in its messages to the headwall interface. The first transceiver may also automatically transmit a disconnect signal to the headwall interface indicating the termination of the communication link is not accidental. The disconnect signal is sent based on one or more of the following: (1) a brake being off, (2) an A/C power cord being unplugged; and/or (3) a signal strength between the transceivers decreasing.

A seat cushion includes a plurality of inflatable cells, a pumping mechanism, and a manifold or valve system fluidly between the pumping mechanism and the inflatable cells. The manifold or the valve system, which may include a clutch and a motor, connect the pumping mechanism with, the inflatable cells such that a plurality of zones are created. A valve assembly can include a plurality of valves and is adjustable among at least three valve configurations to vary fluid connections to the inflatable cells to produce rearwardly advancing waves. The pumping action produced by the inflation and deflation of the inflatable cells assists in pumping blood in a user's legs back toward the heart.

A patient support apparatus may include a foam frame defining a space. A bladder assembly may be positioned in the space. The bladder assembly may include a plurality of foam filled bladders. Each of the foam filled bladders may be interconnected by a manifold. A plurality of mutually exclusively selectable pressure relief valves may be provided to release air from the bladder assembly.

A multifunctional nursing mattress, which includes a mattress main body. The mattress body includes a plurality of inflatable bags arranged in parallel with each other, a mattress cover for wrapping the plurality of inflatable bags, a back lifting inflatable bag, a left-side overturning inflatable bag, a right-side overturning inflatable bag and a foot lifting inflatable bag arranged under the mattress main body. The anti-bedsore mattress of the present invention has the advantages of simple structure and reasonable design, and can realize the functions of back lifting, turning over and foot lifting, which is advantageous for the user to adjust the body posture and has the preventive effect on bedsore.

A mobility device for assisting a patient includes a frame having a wheel arranged to maneuver the mobility device; a lift assembly coupled to the frame and movable between a lowered position and a raised position; and a support arm coupled to the lift assembly for movement with the lift assembly and arranged to support an upper part of a body of the patient and to support at least part of his weight on the mobility device when the lift assembly is raised from the lowered position to the raised position and when maneuvering the mobility device.

A patient support apparatus includes a frame having a supporting surface. A transmitting element is coupled to the frame. A surface assembly is selectively positioned on the supporting surface. The surface assembly includes a surface selectively enclosing an interior. A controller is communicatively coupled to the transmitting element. A sensor assembly is coupled to the surface assembly. The sensor assembly includes a sensor configured to sense information about at least one of the surface assembly and a person positioned on the surface assembly. A receiving assembly is operably coupled to the surface assembly and the sensor assembly. The receiving assembly is configured to selectively interact with the transmitting element via a charging interface to power the sensor assembly.

A support surface includes a patient fluid support surface that includes a first set of inflatable portions having an adjustable width and a second set of inflatable portions having an adjustable length, the width and length both adjustable by changing an amount of fluid in each of the first and second inflatable portions and a controller housing that includes a user interface device and a controller operative to provide control of both inflating and deflating of the first and second set of inflatable portions in response to electronic control signals from the user interface device.

A patient support apparatus comprises a plurality of load cells, a frame supported on the load cells, a mattress, a plurality of air pressure sensors, and a control system. The mattress includes a plurality of inflatable zones positioned on the frame, the mattress and frame cooperating to direct any patient load through the mattress and frame to the load cells. Each of the plurality of air pressure sensors measures the pressure in a respective inflatable zone of the mattress. The control system includes a controller operable to receive a separate signal from each of the plurality of load cells and each of the plurality of air pressure sensors and process the signals to identify motion of the patient. The motion of the patient is further processed by the controller to characterize the nature of the patient motion and, based on the characterization of the patient motion, the controller automatically updates a patient profile in a patient record to reflect the characterization of the patient motion.
