A heating tool (100) according to the present invention includes a steam generator (10) that a heat generating layer (11) which contains an oxidizable metal, a carbon component, a water absorbent polymer, and water, and a water absorbent sheet (102) which carries water are laminated, and a bag (20) at least a portion of which has an air permeability and accommodates the steam generator (10), in which a mass ratio of the water absorbent sheet (102) is equal to or greater than 0.9 and equal to or less than 15 with respect to the water absorbent polymer contained in the heat generating layer (11).

A device comprising a heat-generating component that comprises an alkali metal is provided. The alkali metal in the presence of water at a point of contact of the device undergoes an exothermic reaction to generate heat in situ. The amount of heat generated is proportional to and/or limited by the amount (or moles) of water at the point of contact, and the heat generated is sufficient to achieve an increase in temperature at the point of contact to achieve a therapeutic or beneficial result. In one embodiment, the device is used for reducing sweat production in a subject suffering from excessive sweating or hyperhidrosis. In other embodiments, the device is used to substantially sterilize a surface or render a surface substantially aseptic.

An exothermic warmer (1) includes an exothermic element (11) that is covered with a first cover sheet (21) and a second cover sheet (22). The first cover sheet (21) is a sheet that is air permeable and does not substantially limit an oxidation reaction. A water-retaining material (12) is provided so as to be at least partially in contact with the exothermic element (11). The exothermic warmer (1) satisfies the following conditions (A) to (C): (A) the difference between the internal temperature of the exothermic element and the highest surface temperature of the exothermic warmer is 10 C. or less; (B) the highest skin temperature obtained when the exothermic warmer is applied to human skin is 38 C. or more and 42 C. or less; and (C) the ratio of the amount (mg/cm.sup.2.Math.10 min) of steam generated in 10 minutes after the start of the oxidation reaction to the mass (g/cm.sup.2) of the exothermic element takes a value of 50 or more and 250 or less.

Wearable device is disclosed to quickly deliver thermal treatment. port. A separate material or component is later added through a port at point of injury or a medical event. Wearable thermal device comprises: at least one containment pack of selected shape; containment pack(s) contains a selected amount of first material (preloaded component); at least one port is attached to containment pack(s) configured to accept a second material (second component); and said second material is added through said at least one port to create a chemical reaction when combined with said first material. In one embodiment, first material needed to create an endothermic reaction is a selected amount of ammonium nitrate contained within wearable hypothermic treating device. A port or valve is configured to accept water. When a selected amount ammonium nitrate is combined with water a selected amount of thermal mass is created.

The invention relates to an eye mask for treating dry eyes and other eye conditions related to blepharitis or meibomian gland dysfunction. The eye mask acts as a warm compress which ensures the eyelids are heated to expedite eyelid expression to balance out the tear film and treat dry eyes. In one embodiment, an eye mask for treating an ocular condition includes: a fabric having a first layer and a second layer opposite the first layer; and a heat diffusing fill material enclosed between the first and the second layers. The first layer and the second layer are stitched together substantially along their edges. The fill material is configured to deliver a moist heat to an ocular surface.

A tape 400 or wrap is provided which includes first and second elongated elastic layers 345, 346 sized to conform to the shape of a portion of the external skin of the body of a wearer; and a heated area comprising an exothermic material 310 sandwiched between said first and second elastic layers 345, 346, wherein said exothermic material 310 is activated by exposing said exothermic material 310 to oxygen; wherein said tape 400 or wrap has a elasticity of at least about 10-90% and said heated area is capable of substantially expanding and contracting with the tape or wrap. Methods of using the tape 400 or wrap are also provided.
