A system and method for providing a universal wrap that can apply a thermal pack to many different regions of a patient's body. The universal wrap is provided in a standardized form. The medical provider is provided with options to modify the standardized form in order to adapt the wrap to many different applications.

Polymers, hydrogels, and thermochromic agents, including products embodying them, methods of using them, and processes for making them. In certain embodiments, temperature therapy packs which utilize thermochromic agents integrated into solid, semi-solid, or liquid hydrogels. In preferred (but optional) embodiments, the thermochromic agents are integrated into the composition used as the temperature exchange material of the therapy pack. In certain other embodiments, methods of using the thermochromic integrated temperature exchange materials, or processes for manufacturing such thermochromic integrated temperature exchange materials and/or methods or processes for manufacturing or using thermal packs embodying such materials. In certain particularly preferred embodiments, novel polymer compositions and/or processes for making polymers, which improve product durability or longevity and/or which improve use cycles or usage times.

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 invention relates to a textile fabric made of a fleece comprising a super absorbing activation, to a method for producing the textile fabric, to a covering surrounding the textile fabric, to a cooling system using the covering and to a covering designed as a cooling item.

Disclosed is a cooling pack for a head including an outer cover fixed at an inside of the head protector. The outer cover adheres to a top of a human body, a refrigerant is embedded in the outer cover, and a plurality of fixers are coupled to the outer cover. The fixers are attachable to or detachable from the head protector, and the refrigerant is formed of a polyester polymer powder.

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.

The present invention provides a microwavable Phase Change Material and product thereof, particularly, the present invention relates to the field of microwave heating and use of microwave susceptor for providing heat to Phase Change Material. The invention provides a new process for preparing improved Phase Change Material which can be heated in a domestic microwave oven. The inventive composition comprises of a microwave susceptor which helps the Phase Change Material to melt within a few minutes depending upon the quantity of Phase Change Material taken. Microwave susceptor is at first uniformly mixed with some other material. The other material may be a highly conductive material, or a slow susceptor. Then this composite is incorporated in a Phase Change Material. This susceptor composite initiates uniform melting of Phase Change Material when exposed to microwave irradiation. This microwavable Phase Change Material is free of sparking, arcing and local overheating.

A flexible cold pack includes a cell layer and a flexible layer. The cell layer includes a plurality of cells that are coupled to one another. Each cell of the plurality of cells includes a first liquid associated with a first freezing temperature. The flexible layer is disposed adjacent to the cell layer such that the flexible layer spans the plurality of cells of the cell layer. The flexible layer includes a second liquid or flexible semi-solid disposed therein. The second liquid or flexible semi-solid is associated with a second freezing temperature that is lower than the first freezing temperature.
