A protective device for maintaining body temperature in a living being is provided. The inventive protective device comprises a first sheet member having a left portion and a right portion. The first sheet member has a left edge and a right edge. A first channel member defines structure defining a first channel. The first channel member defines structure which is secured to and overlies a first portion of the left portion of the first sheet member and overlies a first portion of the right portion of the first sheet member. A second channel defining structure defines a second channel, the second channel defining structure secured to and overlying a second portion of the left portion of the first sheet member and overlying a second portion of the right portion of the first sheet member. Each of the channels have a first side and an opposite side opposite the first side. A variable length member is disposed on and extends along the length of each of the channels. There is a connection structure positioned proximate the left edge; and a mating connection structure positioned proximate the right edge.

The garments described herein cool the human body and effectively reduce the working environment temperature. They can also reduce the temperature of the human body in time when exercising. The garments are provided with seals that improve fit and define a relatively closed space within the garments such that cold air is not easily emitted, which enhances the cooling effect.

A main garment body 1, which is formed using a cloth C that is gas-impermeable or is gas-permeable to the extent that the cloth can be inflated by the introduction of air by a fan 2 and which comprises a fan installation hole 13 for installing a fan 2, and an air discharge part 14 for discharging the air introduced by the fan 2, the main garment body having an outer surface space-maintaining means 17, a back body section inner surface space-maintaining means 18, and a front body section inner surface space-maintaining means 19 for maintaining a space between the cloth C and the wearer's body and/or between the cloth C and another garment worn over the main garment body 1. As a result thereof, it is possible to provide a main garment body of an air-conditioning garment and an air-conditioning garment for which the function is not easily reduced even when worn under another garment, etc.

The invention relates to a composition comprising 50-99 wt. % of Na.sub.2SO.sub.4.10H.sub.2O and 0.1-5.0 wt. % of an alginic acid salt. Such composition may advantageously be used as a phase change material since the composition (and a pouch comprising the composition) remains flexible during the phase change. This was also the case when subjected to a high number of subsequent cycles of heating and cooling.

A temperature controlled garment or bra system can be integral with a bra or a separate thermal insert that can be coupled to any type of garment. The thermal insert having one or more thermal zones or regions that are configured to form a temperature gradient for different breast regions for the purpose of having a uniform breast implant temperature.

A wireless charging system for heated garments includes a garment body, a heater coupled to the garment body, a receiver coupled to the garment body and configured to wirelessly receive power, an energy storage element coupled to the garment body and configured to store charge provided to the receiver, a controller selectively providing power from the energy storage element to the heater, and a power supply including a transmitter configured to wirelessly provide power to the receiver when the transmitter is near the receiver.

A garment for patients receiving medical treatment is disclosed. The garment has a sleeve that has an outer surface and an inner surface each made of a first material, a fastener coupled to the sleeve and configured to open and close the sleeve, an inner lining attached to the inner surface of the sleeve. The inner lining is made of a second material that has a higher elasticity than the first material. The garment has a series of pockets disposed on the inner lining configured to hold a heating element to keep the patient's arms warm while in the treatment position.

A cooling knee pad includes a housing having a base, a perimeter wall extending upwardly from the base, and an upper end defining an interior volume. A pad is affixed to the upper end of the housing. A power supply is operably connected to a cooling mechanism disposed within the interior volume of the housing. The cooling mechanism may include a Peltier cooling unit including a radiator, an electric fan, a water pump, and at least one buck converter. A pair of adjustable fasteners affixed to the housing is configured to secure the housing to a user such that the pad contacts a knee of the user. In this way, the user can kneel on the pad to comfortably support the knee and cool the knee with the cooling mechanism.
