A long-acting ice pack includes a mixture of a cold preservation substance and a gel therein. The gel is mixed with a plurality of heat-insulating particles. For a portion of the ice pack, the heat-insulating particles can be used to block the transmission of the interior temperature of the ice pack and the outside temperature so as to decrease the area and efficiency of temperature transmission. The ice pack not only effectively extends the time of cold preservation, meeting the demand of ice compress or cold preservation for a long time, but also provides the most comfortable temperature for ice compress, without using a towel to cover the ice pack.

A hand warmer with double-sided heating is provided. The hand warmer includes a hand warmer body with a cambered surface on one side and a flat surface on the other side. Through the flat surface of the hand warmer body, two hand warmer bodies can be attached together. The hand warmer body includes an outer shell, a heating film disposed on each of two sides of the outer shell, and an aluminum alloy thermally-conductive cover plate covered on the heating film. The outer shell is internally provided with a Hall switch that is tightly attached to the flat surface and a magnetic steel located on a side of the Hall switch. Flat surfaces of the two hand warmer bodies are opposite and attached to each other.

The subject matter of the invention relates to therapy wraps for the application of compression and/or thermal therapy to a patient. The wraps are formed of at least two layers of material which are sealed together to form at least one cavity between them. The wraps may be used in conjunction with a therapy machine which fills the cavity or cavities of the wraps with fluid such as a gas and/or a liquid. The unique shapes of the wraps are particularly suitable for providing therapy to the human body. The shapes permit the manipulation of the wraps around various portions of the human body such as the shoulder, back and foot.

Embodiments described herein relate to a reusable chemical cold pack. The apparatus includes a body which defines a chamber having two volumes separated by a thin film composite membrane. The thin film composite membrane includes a fabric material sheet, a thermoplastic polymer material sheet, and a polyamide material sheet. A first volume disposed on one side of the thin film composite membrane contains a solvent and a second volume disposed on an opposite side of the thin film composite membrane contains a solute. A check valve is disposed through the thin film composite membrane and enables mixing of the solvent and the solute. The solvent and the solute may also be separated after mixing by diffusion of the solvent through the thin film composite membrane.

A device for warming a human body. The device is a gown that has a body with a thorax portion and a leg portion. One embodiment prevents redistribution hypothermia with a distributor attached to the inside of the leg portion. The sleeves, leg portion, and posterior of the gown are heat reflective. The anterior of the thorax portion of the gown is non-reflective. The distributor inflates when heated air is supplied. The distributor exhausts air into the gown. Temperature is maintained at a desired level for the extremities, while preventing the thorax area from being elevated to an uncomfortable level. Another embodiment is a perioperative warming device. The device is a gown that has a thorax portion and a leg portion. Each portion has an independent air chamber and inlet. The two portions are releasably connected. The sleeves, leg portion, and anterior of the gown are heat reflective.

A device and method for reducing heat loss in at least one region of a subject's body is described. The device includes a mask component, a heat releasing reservoir, and a conduit connecting the mask component to the heat releasing reservoir and creating an airflow path therethrough, wherein the heat releasing reservoir includes at least one air permeable region that is impermeable to condensed water. Heat loss is reduced by the subject positioning the mask over the mouth and/or nose, positioning the heat releasing reservoir over the region of the subject's body, and passing warmed air exhaled by the subject into the mask through the conduit and into the heat releasing reservoir, such that the warmed air passes through the heat releasing reservoir while retaining condensed water within the heat releasing reservoir, thereby increasing the temperature of the air surrounding the at least one region of the subject's body.

An object of the present invention is to provide an exothermic device which is capable of reaching a high temperature upon use, and capable of sustaining a high temperature state for a prolonged period of time. The present invention provides an exothermic device (1) including: an exothermic agent (5); and a packaging material enclosing the exothermic agent (5). The packaging material is in the form of a flat bag composed of a first surface and a second surface. Each of the first surface and the second surface includes a breathable region (2) and a non-breathable region (3).
