A method for monitoring an environment for a patient on a patient support device can include: receiving a temperature reading from a wireless sensor coupled to a body of the patient; comparing the temperature reading to air flowing through an airflow system associated with the patient support device; and modifying the air flowing through the airflow system.

A patient warming system for stabilizing and/or heating and cooling a patient includes a plurality of solid-surface sections arranged for attachment to a surgical table and a warming pad layer comprising a plurality of warming pads configured for removable connection to the plurality of solid-surface sections. At least one of the plurality of solid-surface sections includes a power connector for connection to an external power source. Each warming pad of the plurality of warming pads includes a foam insulation layer, a distributed heating element layer having a warming-pad power connection for connection to the power connector, an isothermal layer, and a flexible waterproof layer. Power supplied to the warming-pad power connection of the distributed heating element layer of the respective warming pad can be used to provide a user-selected uniform temperature over the surface of the flexible waterproof layer in order to prevent hot spots.

An inflatable mattress that has multiple chambers is disclosed that includes a first section with a first pressure valve, and a second section that has a plurality of collapsible airtight vertical cylindrical chambers displaced across the first section and which defines a top surface and each vertical chamber includes valves, controlled by a central controller that is programmable and controls the flow of air in and out of each chamber, thereby providing a method to alter the vertical dimension of each chamber and affect movement to a person on the top surface mattress.

A patient support apparatus may include a support surface configured to conduct air along a top face of the support surface so that heat and moisture from a patient lying on the support surface are drawn away from the top face of the support surface. An opening may be formed in a side of the support surface. A cavity may extend from the opening into the support surface. An inlet port may be positioned within the cavity and fluidly coupled to the top face. A blower assembly may be configured to position within the cavity. The blower assembly may have an outlet port that couples to the inlet port when the blower assembly is positioned within the cavity. The blower assembly may conduct air through the inlet port to the top face of the support surface.

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.

A temperature modulation system for a bed, blanket, or other furniture includes a fluid for moderating temperature change, a number of conduit circuits for directing the fluid through respective zones, a control unit including a thermoelectric device for modulating temperature of the fluid, and a pump. Each of the conduit circuits selectively and independently directs fluid through its respective zone in order to produce a temperature within the zone that is independent of the temperature outside the zone. The system also includes an arrangement of one or more zones in an arrangement in which the control unit is programmed to vary the zone temperature over time according to a schedule.

A patient support apparatus includes a support surface including a topper. An opening is formed in a side of the support surface. A cavity extends from the opening into the support surface. An inlet port is positioned within the cavity and fluidly coupled to the topper. A pneumatic blower is configured to removably position within the cavity and has an outlet port that couples to the inlet port.

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.

A microclimate management system including a person support surface including one or more sensors, a fluid supply device coupled to an inlet of the person support surface and configured to supply fluid to an outlet the person support surface, and a controller configured to detect an inlet condition value at the inlet of the person support surface, detect an outlet condition value at the outlet of the person support surface, determine a difference between the inlet condition value and the outlet condition value, and transmit a first alert in response to determining that a rate of change of the difference between the inlet condition value and the outlet condition value is below a lower condition threshold.

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.
