Disclosed is an article consisting of at least two sheets stacked and welded to define a paving including at least three tiles, each having at least three sides and vertices, arranged to define a plane, the tiles being adjacent and connected to each other by at least one of the sides, the tiles including at least one compartment including at least a material absorbent to an aqueous medium or a filler material, the tiles being closed and connected to each other by at least one weld. The weld includes a frangible line with a series of weakening welds and junction points or a pre-cut bordered to either side with a mix weld, the mix weld being broadened close to the vertex of each tile so the corner of the tiles is reinforced by an enlarged weld surface area. Also disclosed are a production method and a device.

Disclosed is a system which employs a cooling or heating pad which is preferably a thin, flexible pad for placement at an intended area of the body. The pad includes a layer of highly conductive material which can be cooled or heated using a portable source of heat or cold material delivered to the conductive material by a delivery conduit. Valves can be included to regulate flow of the cooling or heating material from the source to the pad. The system can also include a dual-chambered canister for containing two different media for heating, cooling or for alternating heating and cooling the pad.

A warming device containing a topsheet to be located close to a skin of a user, a backsheet to be located far from the skin of the user, and a heat generating element interposed between the topsheet and the backsheet. The heat generating element contains an oxidizable metal, a carbon material, an electrolyte, and water, the heat generating element is configured to generate vapor from the heat generating element itself as heat is generated, the topsheet includes a breathable fiber sheet including fibers containing at least a polyethylene terephthalate resin, and the topsheet contains first fibers having a fiber diameter of more than 15 ?m in plan view as measured by observation under a scanning electron microscope.

A cooling headgear is disclosed. Absorbent material within the headgear retains cold water. When worn by a user, the headgear holds the cold water to the head of the user, cooling the user.

An outer bag for disposable body warmer packaging and a disposable body warmer are provided that are excellent in a gas barrier property that inhibits permeation of oxygen gas, water vapor, and the like, which can allow swelling due to hydrogen gas generated during a storage period to be prevented.

Provided is an outer bag for disposable body warmer packaging having an accommodating portion accommodating a disposable body warmer accommodated in an air-permeable inner bag and generating heat through contact with air, the outer bag comprising a low air-permeability portion having an oxygen permeability of 1.5 to 20 cc/m.sup.2.Math.day.Math.atm measured at 20? C. and 90% RH and having a water vapor permeability of 0.05 to 10 g/m.sup.2.Math.day measured at 40? C. and 90% RH; and an air-impermeable portion having an oxygen permeability of 1.3 cc/m.sup.2.Math.day.Math.atm or lower measured at 20? C. and 90% RH and a water vapor permeability of 2.0 g/m.sup.2.Math.day or lower measured at 40? C. and 90% RH, wherein a ratio of an area of the low air-permeability portion to a total internal area of the accommodating portion is 15 to 75%.

A topical temperature therapy device that imparts known temperatures as a function of time to the therapy skin surface of a user during the course of therapy. The skin surface can be intact or breached through injury or surgery. The therapy temperature and time profile can be varied by varying the selections of, among several parameters, the formulation of the heat exchange material and the material and dimensions of the heat exchange material container, thus meeting the needs of a wide range of injuries and demographics. The therapy device contains a temperature indicator indicating the temperature of the heat exchange material in real time. The therapy device further provides visibility to the therapy skin surface during the course of the therapy to allow visual inspection of the therapy area as means to improve therapeutic outcomes. The therapy device is flexible and conforms to the anatomy of the therapy area.

A cooling headgear is disclosed. Absorbent material within the headgear retains cold water. When worn by a user, the headgear holds the cold water to the head of the user, cooling the user.

A heat exchanging pack comprises a substance receiving portion, a first strap receiving portion disposed adjacent a first side of the substance receiving portion, a second strap receiving portion disposed adjacent a second side of the substance receiving portion, and a strap configured for releasably coupling the heat exchanging pack to a portion of a body. The strap includes a first portion extending through the first strap receiving portion, a second portion extending between the first strap receiving portion and the second strap receiving portion, a third portion extending through the second strap receiving portion, and a fourth portion extending out from the first strap receiving portion. The second portion and the fourth portion of the strap are configured to extend at least partially around a portion of a user in need of treatment to releasably couple the heat exchanging pack to the portion of the user.

A manufacturing method for an ice/hot compress product includes the following steps: providing a polyester fiber cloth as an outer layer; adding a thermochromic material into the outer layer when the outer layer is dyed; and attaching an inner layer to an inner side of the outer layer to which the thermochromic material has been added to form a composite-layer material; manufacturing a container through the composite-layer material.
