A flexible evaporative cooling pad includes a fabric base and at least two rows of fabric chambers affixed to the base. Each row of fabric chambers includes a first hydrogel-containing fabric chamber and an adjacent hydrogel-containing fabric chamber. Stitching isolates the hydrogel in each hydrogel-containing fabric chamber. The cooling pad cools under the legs or the head and neck and promotes the sleep cycle. In addition, the cooling pad may be used to treat headaches, fever, and hot flashes or just to cool down when it is hot. Use of an evaporative cooling pad may reduce the demand for air conditioning.

The present invention comprises a heat transfer vest. The vest is configured to mount a plurality of heat transfer packs on its interior surface. In the preferred embodiments the appropriate portions of the interior surface are covered in a hook-compatible material. In these versions, the thermal transfer packs include one or more hook panels that are used to attach the packs to the interior surface.

A medical pad for exchanging thermal energy between a targeted temperature management (TTM) fluid and a patient. The medical pad includes a fluid containing layer configured for circulation of a TTM fluid therein. The pad may further include a bistable stiffening structure configured to transition between a first stable shape and a second stable shape. The pad may further include a thermally-conductive compressible foam layer disposed between the fluid containing layer and a patient contact side of the pad. a self-adhering stretchable band configured to secure the pad to the patient. The pad may further include a semi-permeable layer disposed between an underside of the fluid containing layer and a hydrogel layer so that the TTM fluid may migrate from the fluid containing layer to the hydrogel layer.

A heat sleeve for selectively heating a residual limb of an amputee is provided. The heat sleeve includes a first sock member having an open proximal end, a distal end and a continuous side wall, all defining an open interior area configured to receive the residual limb therein. A temperature regulating apparatus includes a thermal adjustment element adapted to be mounted onto an exterior surface of the first sock member proximate the distal end, and a power supply operatively coupled to the thermal adjustment element. When the power supply is in its ON orientation and providing power to the thermal adjustment element, the thermal adjustment element selectively heats the residual limb within the first sock. A second sock member may then receive the residual limb, the first sock member and the flexible heating element therein.

An object of the present invention is to provide a heat-generating device with which a warm sensation is persistently perceived, and which can effectively exert a heating effect. In a heat-generating device that is used by being attached to skin, (1) a packaging material constituting a skin attachment surface of a housing is formed of a laminated sheet in which at least a moisture absorption layer that absorbs moisture and a moisture barrier layer that blocks penetration of moisture are laminated in this order from the adhesive layer, (2) an adhesive layer is partially provided on a surface of the moisture absorption layer, and (3) a warming agent that allows an enhanced warm sensation to be perceived in the presence of moisture is contained in at least one of the adhesive layer and the moisture absorption layer. This heat-generating device thereby has improved persistence of a perceived warm sensation, and can exert a markedly high heating effect.

The invention concerns the manufacture of personal care articles consisting of compresses having a cooling effect by swelling with water which are presented individually in vacuum packaging. According to the invention, successive doses of powder comprising absorbent particles are placed in grooves formed by elastic deformation in a lower sheet made of water-permeable textile material, which is continuously unwound, and covered with an upper sheet, which is continuously unwound at the same time as the lower sheet. The lower sheet is then heat-welded in the intervals between adjacent grooves thus isolating the grooves from each other. Successive compartments each containing a dose of the powder are then enclosed in each groove by heat-welding the sheets along transverse weld lines across the width of the moving sheet assembly.

Wearable heat transfer devices and associated systems and methods are disclosed herein. In some embodiments, a representative heat transfer device can comprise (i) thermoelectric components each having a first side and a second side, (ii) a heat transfer system having a heat exchanger and an array of fluid distribution networks, in which individual fluid distribution networks are thermally coupled to the second side of a corresponding one of the thermoelectric components and fluidically coupled to the heat exchanger, and (iii) a flexible support unit coupled to the first sides of the thermoelectric components and extending at least between individual thermoelectric components, wherein the flexible support unit is a heat spreader configured to enhance heat transfer from a target area.

Disclosed herein are targeted temperature management (“TTM”) systems, pads, and methods thereof for treating burn wounds. A method of a system for TTM can include a pad-connecting step, a pad-placing step, and a fluid-circulating step. The pad-connecting step can include connecting an inlet and an outlet of a pad to a hydraulic system of a control module. The pad can include a multilayered pad body having a conduit layer configured to convey a temperature-controlled fluid provided by the control module. The pad-placing step can include placing the pad on a wounded portion of a patient's body with a sterile, thermally conductive wound-healing layer of the pad body in contact with a burn wound of the wounded portion of the patient's body. The fluid-circulating step can include circulating the temperature-controlled fluid through the conduit layer to cool the wounded portion of the patient's body, thereby treating the wound to promote healing.

A heating device having at least one package surrounding a hygroscopic salt and a heater mix having at least a metal reactant. The heating device may include a source of moisture positioned in the package, the source of moisture initially generating an atmosphere having nearly 100% relative humidity inside the package. The hygroscopic salt is spatially separated from the source of moisture within the at least one package and positioned so as to absorb moisture out of the atmosphere to form an electrolyte, and the hygroscopic salt is further positioned so that the electrolyte generated by the hygroscopic salt is in contact with the heater mix. Rather than have an internal source of moisture, the at least one package may be water vapor permeable to allow ambient moisture from the atmosphere to enter the interior of the package to combine with the hygroscopic salt to generate an electrolyte.

Provided are devices for therapeutic interaction with an Abreu brain thermal tunnel (ABTT) terminus. Such devices are configured to provide one or more drugs to an ABTT terminus, and may provide heat to or remove heat from the ABTT terminus while providing the one or more drugs.
