A means can be used instead of or with conventional temperature control to achieve warming device temperature control at a lower cost, prevent or reduce deterioration of a warming device over time, and lower generated heat temperature due to storage at high temperatures. The warming device can be used for the same. A higher level temperature control means can be used for warming devices for medical applications. An improved warming device can be used for medical applications with a high level of safety and efficacy. A temperature control agent controls a maximum temperature of a warming device with a heat generating composition that generates heat by reaction with oxygen. Said agent includes an aliphatic compound that has a particle form that will not pass through a standard sieve with a #60 mesh, a melting point of 35-65? C., and an aqueous solubility (g/100 mL) at 20? C. of ?5.

A cooling garment for use by workers in hot, humid climates comprising: a moisture-wicking under layer; an outer layer with an air permeability less than 200 L/m.sup.2/s when subjected to 125 Pascals of air pressure; at least one air channel formed between the layers and supported in at least some locations by a porous filler material; and an above ambient pressure gas supply attached operably to the inlet of the channel. Also a cooling garment comprising: a moisture-wicking under layer; an outer layer; one large air channel formed between the layers; tacks connecting the outer layer to the moisture-wicking under layer to prevent ballooning; and an above ambient pressure gas supply operably attached to the inlet of the channel.

The present invention relates to a novel cryogenic composition intended to be used in thermal treatment devices, and also to its process of preparation. The invention also relates to a thermal treatment device and more particularly to a medical device used to cool a part of the human or animal body, in particular after trauma, inflammation or a surgical act. The invention has application in the therapeutic and/or medical field but also in other fields, such as, for example, for the cooling or the maintenance at low temperature of foodstuffs.

An object of the present invention is to provide a heat-generating device with which a warm sensation is persistently perceived, and which can effectively exert a heating effect. In a heat-generating device that is used by being attached to skin, (1) a packaging material constituting a skin attachment surface of a housing is formed of a laminated sheet in which at least a moisture absorption layer that absorbs moisture and a moisture barrier layer that blocks penetration of moisture are laminated in this order from the adhesive layer, (2) an adhesive layer is partially provided on a surface of the moisture absorption layer, and (3) a warming agent that allows an enhanced warm sensation to be perceived in the presence of moisture is contained in at least one of the adhesive layer and the moisture absorption layer. This heat-generating device thereby has improved persistence of a perceived warm sensation, and can exert a markedly high heating effect.

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.

The present invention comprises a heat transfer vest. The vest is configured to mount a plurality of heat transfer packs on its interior surface. In the preferred embodiments the appropriate portions of the interior surface are covered in a hook-compatible material. In these versions, the thermal transfer packs include one or more hook panels that are used to attach the packs to the interior surface.

The disclosure concerns an improved system for administering moisture therapy to a patient, the system including: a conventional moisture therapy compress, and a therapeutically adaptive cover configured to contain the conventional moisture therapy compress and further adapted to communicate a therapeutic delivery of hot or cold moisture through a fluid permeable material to a treatment site of a patient. The therapeutically adaptive cover communicates hot or cold moisture therapy while isolating the compress from the treatment site, allowing for re-use of the compress by way of replacing the cover, or washing the cover prior to subsequent use for maintaining optimum sterility and cleanliness. Other features and advantages are disclosed in the appended detailed description of the preferred embodiments.

The invention relates to a bandage comprising a flat web material as a substrate, wherein a self-adhesive cohesive adhesive compound is at least partially applied to both flat sides of the substrate, and the substrate is impregnated with a liquid preparation, characterised in that said adhesive compound comprises an anhydrous cohesive pressure sensitive adhesive which contains natural and/or synthetic rubber, this natural and/or synthetic rubber being dissolved in an organic solvent for application, or the pressure sensitive adhesive being molten for application.

A system for delivering thermal therapy to a treated body portion of a subject. The system preferably includes a therapy compress having at least one pocket or retainer, and at least one self-heating element configured for removable insertion within the at least one pocket of the therapy compress. In some example embodiments the therapy compress is in the form of an eye mask having first and second eye-covering lobes, each eye-covering lobe having a pocket for receiving a self-heating element. In some example embodiments the at least one self-heating element is air or oxygen activated, for example including a zinc-based self-heating material.

The pressure relief device for ears includes first and second ear assemblies, corresponding to first and second ears of a user, and a resilient headband. Each of the first and second ear assemblies includes a hollow vapor chamber, an earpiece, a container and an absorbent pad. The hollow vapor chamber includes an upper portion and an open lower portion. An open internal channel is formed through the hollow vapor chamber. The earpiece has an opening formed therethrough and is adapted for engaging the corresponding ear of the user. The earpiece is secured to the upper portion of the hollow vapor chamber, and the opening is in open fluid communication with the open internal channel. The container is releasably secured to the open lower portion of the hollow vapor chamber and is in open fluid communication with the open internal channel. The absorbent pad is removably received in the container.
