This invention is a device or system which modifies the temperatures of one or more climate zones on a bed using liquid-flow tubes (or channels) which are inside air-flow tubes (or channels). The locations and shapes of the climate zones can be customized by one or more people in the bed.

A noninvasive, brain cooling method and device for cerebral cooling via a patient's nasopharyngeal cavity, is described. Thermal conductive nasal prongs are inserted into a nasal cavity and are cooled by thermoelectric cooling elements. An outward air driving fan inside the device drives a cold air current through the nasal and oral cavities. Heat transfer between the cold air and the surface of the nasal cavity cools the nasal cavity, which in turn, cools a patient's brain. Real-time temperature sensing data provides feedback for closed-loop cooling control.

A breathing assistance apparatus has a pressurised gases source featuring a lightweight impeller with a plastic shaft. The impeller is shroudless. The plastic shaft is supported within the stator by a bearing structure. A resilient motor mount couples the stator and the housing and provide compliance and/or damping for the motor.

A bed includes components to control temperature of a sleep surface, for example based on time and historical usage patterns by a user. In some embodiments the temperature of the sleep surface is controlled based on information indicating a sleep state of the user. In some embodiments the temperature is dynamically adjusted so to achieve particular sleep states and/or sleep patterns for the user. In some embodiments the temperature and timing of temperature adjustments is iteratively adjusted over multiple sleep sessions so to achieve improvements in sleep states and/or sleep quality for the user.

A water tank mounting structure and a ventilation treatment apparatus is provided. The water tank mounting structure comprises a cavity for containing a water tank, a back wall for defining the cavity, at least one side wall for defining the cavity, and a guiding assembly for guiding the water tank to assemble to the cavity. The back wall is provided with at least one opening for transmitting a respiratory gas between a main unit of the ventilation treatment apparatus and the water tank. The guiding assembly is set such that when the water tank is assembled into the cavity, at least one gas port of the water tank is aligned to the at least one opening of the back wall. The guiding assembly includes at least one first guiding component provided on the back wall and a second guiding component provided on the at least one side wall.

Fluid management systems are disclosed that include software-controlled, electro-mechanical devices used in combination with single-use or multi-use tubing sets. Functions of the fluid management systems can include fluid pressurization, fluid warming, fluid deficit monitoring (including flow-based and weight-based), suction, fluid collection, and fluid evacuation (including indirect-to-drain and direct-to-drain options). The systems can be configured based on the surgical environment (e.g., operating room or physician office) as well as other user needs and/or preferences.

The present disclosure relates to an agitator unit for use with a blood product storage system, wherein the agitator unit has a movable compartment to receive blood products and a drive for movement of the compartment. The drive of the agitator unit has at least one motor and a gear system with at least one planetary gear unit, wherein the planetary gear unit has at least one planet wheel, which is eccentrically movable by means of the motor, and a planet disc, wherein the planet wheel is connected to the compartment by means of a spigot and rolls on an internal periphery of the planet disc, wherein the spigot is adjustable in its relative position. In addition, the disclosure relates to a modular blood product storage system with an agitator unit.

Thermal management solutions for wireless power transfer systems are provided, which may include any number of features. In one embodiment, an implantable wireless power receiver includes at least one thermal layer disposed on an interior surface of the receiver configured to conduct heat from a central portion of the receiver towards edges of the receiver. The thermal layer can comprise, for example, a copper layer or a ceramic layer embedded in an acrylic polymer matrix. In some embodiments, a plurality of thermal channels can be formed within the receiver to transport heat from central regions of the receiver towards edges of the receiver via free convection. In yet another embodiment, a fluid pipe can be connected to the receiver and be configured to carry heat from the receiver to a location remote from the receiver. Methods of use are also provided.

A system for cooling the brain of a human subject, includes a cooling subsystem which inputs a flow of air or breathable gas, cool the air or breathable gas, and output cooled air or breathable gas which is delivered to a human subject. A flow control device to controls a flow rate of the flow of the air or breathable gas input to the cooling subsystem and a flow rate of the cooled air or breathable gas delivered to the human subject. One or more flow rate sensors measure at least a flow rate of flow of cooled air or breathable gas. One or more temperature sensors measure at least a temperature of a brain and the temperature of the flow of cooled air or breathable gas. A controller adjusts a cooling rate, the temperature, and the flow rate of flow of cooled air or breathable gas delivered to the human subject to cool the brain of the human subject.
