A system includes a client application executed by a client computing device for setting up an inflation level and checking an inflation level of an inflatable cushion having at least one air cell or zone and at least one pressure sensor within the cushion that detects air pressure. The client computing device communicates with the inflatable cushion and determines an optimal inflation level for a user of the inflatable cushion.

A system for monitoring medical conditions including pressure ulcers, pressure-induced ischemia and related medical conditions comprises at least one sensor adapted to detect one or more patient characteristic including at least position, orientation, temperature, acceleration, moisture, resistance, stress, heart rate, respiration rate, and blood oxygenation, a host for processing the data received from the sensors together with historical patient data to develop an assessment of patient condition and suggested course of treatment, including either suspending or adjusting turn schedule based on various types of patient movement. The sensor can include one or more of bi-axial or tri-axial accelerometers, magnetometers and altimeters as well as resistive, inductive, capacitive, magnetic and other sensing devices, depending on whether the sensor is located on the patient or the support surface, and for what purpose. In some embodiments, the sensor can be self-contained in that it can detect orientation and suggest repositioning independent of a host.

A vehicle includes a floor. The vehicle includes a first track elongated along a vehicle-longitudinal axis and fixed to the floor. The vehicle includes a roof above the floor. The vehicle includes a second track elongated along the vehicle-longitudinal axis and fixed to the roof. The vehicle includes a post supported by and movable along the first track and the second track. The vehicle includes an airbag supported by the post and inflatable from an uninflated position to an inflated position.

A patient support apparatus includes a bed frame having a head end and a foot end and control circuitry carried by the bed frame. The control circuitry receives information about conditions of the patient support apparatus. A light is coupled to the bed frame adjacent the foot end and is coupled to the control circuitry. The light is in a first state when the patient support apparatus is operating normally and the light is in a second state when the control circuitry detects an alert condition.

An air mattress control system is disclosed. The air mattress control system comprises a mattress and a gas regulating device. The mattress comprises a plurality of inflation layers. The gas regulating device comprises a first three-way solenoid valve, a pumping motor, a second three-way solenoid valve, a connecting conduit, a gas guiding device, and a control device. The pumping motor connects the first three-way solenoid valve and the second three-way solenoid valve connects the pumping motor. The connecting conduit connects the first three-way solenoid valve and the second three-way solenoid valve. The gas guiding device connects the connecting conduit and a plurality of the inflation layer. The control device controls the switch of the first three-way solenoid valve and the second three-way solenoid valve, and starting the pumping motor to inflate or deflate the plurality of inflation layers.

The invention relates to a method for producing a cushion for an orthopedic device, the cushion having at least one fluid-filled volume, wherein the method includes compression molding of a three-dimensional first cushion component made of at least a first material, which is preferably elastic, in a mold that comprises an inner mold and an outer mold, and bonding the first cushion component to at least a second cushion component in such a way that the fluid-filled volume is created.

Sleeping equipment includes: a mat body including a middle support portion configured to support buttocks of a user, an upper support portion configured to support a back and head of the user, and a lower support portion configured to support thighs of the user; a movable mechanism configured to switch the mat body between a bed mode in which the mat body has a flat shape in which the middle support portion, the upper support portion, and the lower support portion are continuous with each other and a comfortable mode in which the upper support portion and the lower support portion are tilted upward with respect to the middle support portion; and a lower back pressing mechanism configured to cause a part of the upper support portion corresponding to a lower back of the user in the comfortable mode to bulge out toward the user.

A support cushion liner includes a liner body having a cavity disposed between an outer layer and an inner layer and a plurality of artificial muscles disposed in the cavity of the liner body. Each of the plurality of artificial muscles include a housing having an electrode region and an expandable fluid region, a dielectric fluid housed within the housing, and an electrode pair positioned in the electrode region of the housing. The electrode pair includes a first electrode fixed to a first surface of the housing and a second electrode fixed to a second surface of the housing. The electrode pair is actuatable between a non-actuated state and an actuated state such that actuation from the non-actuated state to the actuated state directs the dielectric fluid into the expandable fluid region, expanding the expandable fluid region thereby applying pressure to the outer layer of the liner body.

A patient support apparatus comprises a plurality of load cells, a frame, a mattress, a plurality 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 a 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 sensors, and a physiological sensor, process the signals to identify movement data and sleep data and to display the movement data and sleep date on a segmented screen on a user interface.
