An appendage cooling and heating system has a body with an outer layer, an inner layer, and an interstitial space for containing a thermo-regulator material. The inner layer and the outer layer are nested to form a joint. An appendage opening is formed in the appendage cooling and heating system to receive an appendage of the user. The joint forms an interlocking seal between the outer layer and the inner layer to contain the thermo-regulator material within the interstitial space.

A cold and/or hot therapy device that utilizes insulation to maintain its temperature.

A neck wrap for cooling down a neck area of a person. The neck wrap can be worn around a neck and have two pouches. Each of the two pouches can receive a liquid container that can be filled with cold liquid and optionally frozen. The two pouches having a contact area coming in contact with skin made of heat conductive material that can permit removing heat from the neck area by the cold liquid in the liquid containers when the neck wrap is worn around the neck.

An equine cryotherapy overleg device that encircles the lower limb of a subject horse and provides cryotherapy to the subject horse. The one-piece device includes upper and lower fasteners, a pastern area that will hold ice and ice water and a vertical zipper. The arrangement of the hoof cover, and hoof slipper allow for free movement of the subject horse and for a thermal fluid to contain ice and prevent the ice from migrating under the subject horse hoof.

A multi-part safety closure for a hot-water bottle includes at least one closure part (4) having an external screw thread (12) for screwing into an internal screw thread of a hot-water bottle and having a first force transmission element (6) for transmitting force for screwing and unscrewing the closure part (4) into and out of, respectively, the internal screw thread of the hot-water bottle (14) to seal the bottle (14) in a water-tight manner; and a manual actuating element (2) having a second force transmission element (8) for transmitting to the closure part (4) the force required to screw and unscrew the closure part (4) into and out of, respectively, the internal screw thread (17). The first force transmission element (6) and the second force transmission element (8) are configured such that the closure part (4) is operably connectable with the manual actuating element (2) in a detachable manner.

A cold block for cooling an extremity comprises a container defining an internal chamber. A recess is defined in the container. The recess is surrounded, in part, by the internal chamber. The recess is configured to receive an extremity of a person. In use, in one example, the internal chamber of the cold block is filled with fluid, such as water, and frozen. In another example the internal chamber contains a gel that may be cooled or frozen. A patient undergoing chemotherapy may place a respective extremity in one or more cold blocks to decrease neuropathy.

Wearable device is disclosed to quickly deliver thermal treatment. port. A separate material or component is later added through a port at point of injury or a medical event. Wearable thermal device comprises: at least one containment pack of selected shape; containment pack(s) contains a selected amount of first material (preloaded component); at least one port is attached to containment pack(s) configured to accept a second material (second component); and said second material is added through said at least one port to create a chemical reaction when combined with said first material. In one embodiment, first material needed to create an endothermic reaction is a selected amount of ammonium nitrate contained within wearable hypothermic treating device. A port or valve is configured to accept water. When a selected amount ammonium nitrate is combined with water a selected amount of thermal mass is created.

A therapeutic garment for cooling an arm of a user includes a vest that is configured to position over a torso of the user. A sleeve is coupled to and extends from a circumference of an armhole of the vest so that the sleeve is configured to insert the arm of the user. The sleeve comprises an inner layer that is coupled to an outer layer so that the inner layer and the outer layer define an interior space. The interior space extends from a cuff of the sleeve to the armhole. An orifice is positioned in the outer layer proximate to the armhole. The orifice is configured to selectively insert a cooling material into the interior space, positioning the cooling material to cool the arm of the user. A closure is coupled to the outer layer proximate to the orifice and is positioned to selectively and sealably close the orifice.

A mouthpiece having particular suitability for cooling oral tissue of a patient undergoing chemotherapy or other medical treatments in which reducing oral cavity temperature is beneficial. The mouthpiece includes a cooling medium contained within the top element and the bottom element and able to retain a cooling environment within the mouth, preferably sufficient to reduce capillary blood flow to the patient's mouth. In one embodiment, an external chamber extends from the front of the mouthpiece to house a cooling medium. A bladder is positioned inside the external chamber for storing a solution having a freezing temperature above the freezing point temperature of the cooling medium to assist in cooling the cooling medium. At least one breathing tube extends through the external chamber to permit a patient to breathe through the mouth when the mouthpiece is emplaced within the mouth in the operative close-fitting relationship.

Described are various embodiments of a cooling pack. In one such embodiment a cooling pack is provided for cooling a crotch region of a human while seated on a seating surface, the cooling pack comprising a tapered container for holding a cooling material therein, and defined by tapering upper and lower surfaces drawing into a tapered edge to be positioned between the crotch region and the seating surface in use, thereby providing cooling for the region.
