Disclosed is a self-heating thermal-insulation multilayer film comprising a structure of at least three layers, which from outside to inside are respectively: an outer layer (1) formed of an air permeable material; a heat-generating layer (2) loaded with heat-generating composition (21) that generates heat on contact with air, at least an upper sealing surface of the heat-generating layer that is in contact with the outer layer being formed of an air permeable material; and an thermal-insulation layer (3) formed of a material having waterproof and thermal-insulation properties. The present self-heating thermal-insulation film is structurally simple, is not constrained by environmental resources, does not require energy supply from an external energy source, is safe and stable, uniformly generates heat, and can effectively prolong heating time and reduce peak heating temperature. The present self-heating thermal-insulation film can be manufactured into a three-dimensional face mask, a face mask, or an eye mask.

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 is an applicator device for an apparatus used in a localized cryotherapy treatment. The applicator device is configured, when positioned over a body area to be treated, to receive and to uniformly distribute across the entire area covered thereby a stream of medium, such as air, adjusted to a temperature equal to or above −40 degrees Celsius (° C.) and directed, at a predetermined speed, via the applicator to the area to be treated, whereby a cold-induced thermal shock response is developed in skin and an underlying tissue within the area covered by the applicator. Related apparatus and a method are further provided.

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.

Packs for providing heat or cold to a body part or parts. In some embodiments, packs comprising an outer flexible shell or skin housing or carrying a plurality of beads mixed in combination with a liquid or gel. In some embodiments, packs, which can be (or are) configured into various shapes, which contain heads in combination with a liquid or gel solution, which can be heated or cooled for application, thereafter, to a body part for providing hot or cold therapy to the body part.

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.

The invention pertains to an applicator device 10 for an apparatus 100 used in a localized cryotherapy treatment. The applicator device 10 is configured, when positioned over a body area to be treated, to receive and to uniformly distribute across the entire area covered thereby a stream of medium, such as air, adjusted to a temperature equal to or above −40 degrees Celsius (° C.) and directed, at a predetermined speed, via said applicator 10 to the area to be treated, whereby a cold-induced thermal shock response is developed in skin and an underlying tissue within the area covered by said applicator. Related apparatus 100 and a method are further provided.

The present invention relates to a mask-shaped skin treatment device and system. The device comprises one or more coupling agent detectors configured to detect presence of coupling agent on one or more skin portions of a user and one or more heating elements configured to cause local heating of one or more skin portions of the user. The one or more heating elements are configured to cause heat selectively based on the presence of coupling agent measured by the one or more coupling agent detectors.

The embodiments herein provide a method for producing activated carbonaceous balls. The method includes a step of crushing and sizing raw coconut shells to form coconut shell granules having a diameter of about 0.02 mm-2.36 mm, preferably 0.075 mm-1.18 mm. The method includes a step of mixing pure water to a food grade powder appropriately and boiling it slowly at 15° C.-80° C. to obtain a water-food grade powder mixture. The method includes a step of adding the water-food grade powder mixture 20-40% by weight to the coconut shell granules 100% by weight to obtain a slurry in a pourability condition. The method includes a step of pouring the slurry into a pill making machine equipped with a mold of 3 mm, 5 mm, and 8 mm in diameters selectively to produce the spherical carbon tablets. The method includes a step of drying the spherical carbon tablets and carbonizing the spherical carbon tablets to obtain the activated carbonaceous balls.
