A therapy seat cushion, method of making the cushion and method of using the cushion. The cushion has a planar array of at least two sets of alternatively inflatable and deflatable cells controlled by an inflation control system, and at least one non-inflatable offloading cushioning cell interspersed amongst the inflatable cells. The non-inflatable offloading cushioning cell configured and arranged to align with a pressure sore or an area prone to development of a pressure sore on an individual.

A leg pulling device has a traction device and a supporting device. At least one force or at least one pressure which is exerted on a patient by the supporting device upon the actuation of the traction device can be measured.

A posture determination apparatus including at least two vibration sensors and a controller. The controller causes the vibration sensors to detect vibrations while the user is lying in bed, calculates waveforms from the detected vibrations and recognizes the characteristics of the waveforms, and determines the posture of the user based on the characteristics. Thereby, it is possible to provide a posture determination apparatus capable of appropriately determining the posture of the user which is one factor of the state of the user.

A mattress assembly includes: multiple gas-filled chambers each having a top surface, the top surfaces of the chambers collectively composing a top surface of the mattress assembly; multiple composite sensors each associated with a corresponding chamber. Each composite sensor includes a pressure sensor to measure a pressure at a wall of the corresponding chamber and a temperature sensor to measure a temperature of the corresponding chamber. The assembly includes chamber regulators each in communication with a corresponding chamber, each regulator configured to pump gas at a first, higher temperature and gas at a second temperature to the corresponding chamber. The assembly includes a controller in communication with the composite sensors and chamber regulators, programmed to: receive, from composite sensor(s), state data including pressure and temperature information for the chamber corresponding to the composite sensor; determine, based upon the received state data, information about a patient's position relative to the corresponding chamber; and based on the patient's position, control the chamber regulator for the chamber to modify a pressure and/or a temperature of the chamber.

An advanced manually propelled wheelchair (100) is described. The wheelchair (100) has a chassis (110). In certain examples this may be a single piece design. The wheelchair (100) may further have one or more of a load adjustment mechanism (150) and a power-assist mechanism. The load adjustment mechanism (150) is configured to adjust a position of a set of rear wheels (120) for the wheelchair (100) relative to a loading of the wheelchair (100). Load adjustment may be performed based on a sensed loading. The power-assist mechanism provides a powered torque to a set of front wheels (130) to help a user propel the wheelchair (100) or to stabilise the wheelchair (100) during use. The power-assist mechanism may be provided as a set of modular front wheel units.

A posture determination apparatus including at least two vibration sensors and a controller. The controller causes the vibration sensors to detect vibrations while the user is lying in bed, calculates waveforms from the detected vibrations and recognizes the characteristics of the waveforms, and determines the posture of the user based on the characteristics. Thereby, it is possible to provide a posture determination apparatus and capable of appropriately determining the posture of the user which is one factor of the state of the user.

A mattress has a first support portion configure to receive and support a first user and a second support portion configured to receive and support a second user. The first support portion and the second support portion are adjacent to each other such that the first user is capable of rolling over from the first support portion to the second support portion while sleeping on the first support portion. A sensor is configured to sense first pressure in the first support portion and sense second pressure in the second support portion. The sensor is further configured to transmit data of the first pressure and the second pressure. The controller is configured to receive the data and from the data of the first pressure and the second pressure, determine if the first user has rolled over from the first support portion to the second support portion.

A patient support system comprises a patient support apparatus for patients. The patient support apparatus comprises a base and a patient support surface supported by the base. The patient support apparatus also comprises powered devices that perform one or more predetermined functions on the patient support apparatus. Multiple input devices are employed to control the powered devices. The input devices are designed to enable caregivers to cause operation of the powered devices, as needed, while freeing the caregivers to perform other tasks.

A backrest for a wheelchair or other mobility device configured to provide user controllable cooling and heat to the wheelchair user's back. The cooling element includes a Peltier chip, heat sink and gel pad for user contact. The heating element includes heating wire interposed between the fabric cover and the compressible foam of the backrest cushioning. The cooling element and heating element both move with the movement of the fabric cover so as to provide good heat conduction contact without adversely affecting cushioning. The backrest includes a tillable mount.

Described herein are devices, systems, and methods relating to making individuals comfortable when in contact with surfaces (e.g., seats and beds) including preventing pressure injuries on subjects. In embodiments, disclosed herein are pressure injury prevention systems comprising actuator assemblies that can simultaneously provide immersion and offloading of pressure while allowing a subject to retain balance. In other embodiments, moisture control devices and/or sensing networks can be used in conjunction with said actuator assemblies to prevent pressure injuries in a subject in need thereof. In embodiments, also described herein are computing devices and applications that alert a manual intervention or trigger an automated intervention between the individual and the intervention surface based on a risk determination. Such interventions can send instructions to the system to relieve pressure and/or moisture at one or more interface locations on the interface surface between the system and a subject according to a set of rules based on a predetermined profile, data collected continuously in real time, or both.
