An improved medical pad for contact thermal exchange with a patient includes a fluid circulation layer for containing a thermal exchange fluid circulatable therethrough, a first port and a second port for circulating the thermal exchange fluid in to and out of the fluid circulation layer, and a hydrogel layer interconnected to and extending across one side of the fluid circulation layer to define an adhesive surface for adherence to a patient's skin. The hydrogel layer can include an ultraviolet light-cured composition with a cross-linking copolymer, water, and glycerol. The hydrogel layer is provided to have a thermal conductivity of at least about 1.9 ca//hr-cm-° C.

The invention is a cooling unit for a heat exchanger, which preferably is a heat exchanger integrated in an oxygenator for the purpose of controlling the temperature of blood conveyed in an extracorporeal blood circuit. The cooling unit has a reservoir in which a liquid is stored, a reaction vessel comprises a reactant and which, in conjunction with the liquid, is able to initiate an endothermal reaction. A fluidic access is generated between the reservoir and the reaction vessel. A fluid line extends at least in part inside the reaction vessel which has an inlet line and outlet line, which are each connectable or connected in a fluid-tight manner to a hose system of the heat exchanger, which together with the hose system of the heat exchanger, provides least part of a fluid circuit.

In one instance, a recovery system for a user is presented that includes a battery-operated, flexible wrap that applies heat with both conductive heat and radiant heat. The recovery system has a control unit that ramps the temperature applied using primarily perceived conductive heat before leveling at a target temperature. Other systems and devices are presented.

A therapeutic sleeve and techniques for using it are provided. A therapeutic sleeve may house a conduit carrying a constant stream of a chilled or heated working fluid throughout the sleeve. A heating element may evenly distribute heat throughout the sleeve. The sleeve may provide a precise temperature-controlled pocket that significantly improves treatment of pain or discomfort in the user's feet, head, or other body parts. A software application may enable a user to set or adjust a temperature, set timers, record sleep patterns, and view analytics or other data.

A vein heating assembly includes a sleeve that has a first portion which is hingedly coupled to a second portion. The first portion is positionable in an open position to have a patient's arm positioned therein and the first portion is positionable in a closed position to surround the patient's arm. A plurality of nozzles is each integrated into the sleeve. A plurality of heating elements is each coupled to the sleeve to warm the patient's arm when the heating elements are turned on thereby increasing blood flow in the arm for enhancing the appearance of veins. A steam unit is integrated into the sleeve to produce steam that is delivered onto the patient's arm for increasing blood flow in the arm for enhancing the appearance of veins.

A temperature-management device comprises a wearable sleeve including a foot portion configured to cover at least a portion of a sole of a foot of a patient, a calf portion configured to cover at least a portion of a calf of the patient, the calf portion having one or more compression bladders associated therewith, and a popliteal fossa portion configured to cover at least a portion of a popliteal fossa of the patient. The temperature-management device further comprises a heater assembly configured to be secured to the wearable sleeve, the heater assembly including a foot heating pad, a popliteal fossa heating pad, and a physical connector extending between the foot heating pad and the popliteal fossa heating pad.

Wearable heat transfer devices and associated systems and methods are disclosed herein. In some embodiments, a representative heat transfer device can comprise (i) a thermoelectric component (TEC) including a first side configured to be operated at a desired temperature and a second side opposite the first side, (ii) a thermally conductive contact member thermally coupled to the TEC, and (iii) a heat transfer system configured to distribute heat from the TEC. The heat transfer system includes a heat transfer structure thermally coupled to the TEC, and a heat exchanger thermally coupled to the heat transfer structure.

Apparatus and methods for producing thermal comfort using two point or multipoint heating or cooling that is applied to portion of a human body part to produce a warm or cool sensation over a larger area than that where the heating or cooling is directly applied. The body is induced to heat or cool itself by adjusting its neutral temperature setpoints. Increased warming perception from two-point, multipoint, and switching point stimulation causes downward adaptation in the neutral skin temperature of the user. Because spot heating and cooling sources operate at higher temperature differences from the skin than do area sources, they create a stronger perceived thermal sensation for the same power consumption. Point heating or cooling, rather than whole-area heating, can result in power savings and cost savings while improving occupant comfort.

The invention preferably relates to a device for hyperthermal treatment of itching and/or herpes diseases comprising a control device on which at least two treatment programs are stored and an interface for a selection of one of the at least two treatment programs by means of a mobile device, so that after actuation of an operating element the control device heats a treatment surface according to the selected treatment program to a treatment temperature between 40°-65° C. and holds the treatment temperature for a treatment duration between 1 and 12 seconds.

A radiant heat foot warming device including a top planar surface configured to emanate radiant heat therefrom to warm feet of a user; a bottom planar surface spaced apart from the top planar surface; a plurality of curved sidewalls positioned between and connected to the top planar surface and the bottom planar surface; and an adjustable temperature control member positioned on the top planar surface that displays device temperature and further adjustably controls device temperature to regulate radiant heat emanating from the top planar surface.
