Devices for providing thermal therapy to the perineal and rectal areas of a patient are described. The device is particularly useful for containing gushing lochia flow. Different embodiments of the device can be used to provide either hot or cold therapy to the patient. The inventive thermal pack of the current invention comprises a thermal pouch, pad and a backing layer.

A heat generating device including a heat generating element and an enclosing material entirely enclosing the heat generating element. The heat generating element includes a base sheet formed of a fibrous sheet containing superabsorbent polymer particles and hydrophilic fibers and a layer of a heat generative composition containing oxidizable metal particles on a side of the base sheet. The enclosing material includes a first cover sheet and a second cover sheet bonded together in their peripheral portions to provide a space therebetween in which the heat generating member is placed. The heat generating element in the space is in a non-fixed state to the enclosing material. The first cover sheet has air permeability in part and is disposed on the side of the layer of the heat generative composition. The heat generating device is capable of releasing steam from the side of the first cover sheet during use.

The present invention relates to an adhesive sheet for cooling which preferably maintains a cooling effect utilizing the heat of vaporization of water and can exert a persistent high cooling effect.

A vapor heating implement satisfies: (A) the content of water in the heating implement is equal to or higher than 40 parts by mass and is equal to or lower than 80 parts by mass for 100 parts by mass of the oxidizable metal; (B) the content of the water-retention agent in the exothermic composition is equal to or higher than 0.3 parts by mass and is equal to or lower than 20 parts by mass for 100 parts by mass of the oxidizable metal; (C) the content of water contained in the exothermic layer (121A) is equal to or higher than 8 parts by mass and is equal to or lower than 45 parts by mass for 100 parts by mass of the oxidizable metal; and (D) the content of water contained in the water-retention sheet (121C) is from 15 to 30 mass % of the maximum water absorption of the water-retention sheet.

A method for cerebral cooling is described using a cooling assembly, which includes first and second elongate tubular members adapted for insertion into a nasal cavity of a patient through the patient's nostrils. The elongate tubular members each have a proximal end, a distal end, a lumen extending therebetween, and a plurality of ports in fluid communication with the lumen. The cooling assembly also includes a manifold and a reservoir, which contains a pressurized fluid that includes a propellant having a boiling point less than 22 C. The elongate tubular members are inserted into the nasal cavity through the patient's nostrils and pressurized fluid is delivered onto a surface of the nasal cavity by infusing the pressurized fluid from the reservoir through the manifold, into the lumens and through the plurality of ports of the first and second elongate tubular members.

A modified superabsorbent polymer (SAP) comprises a SAP matrix and urea in the form of crystals that is integrated into the SAP matrix. The SAP matrix and the urea are interpenetrated. A method for producing the modified SAP may comprise a) preparing a mixture comprising at least one urea solution and at least one SAP, b) swelling the SAP in the mixture, c) crystallizing the urea in the mixture obtained upon completion of step b), d) recovering the modified SAP in the mixture, and e) optionally, forming the modified SAP recovered at step d).

A heating element (10) comprises an exothermic layer (11) containing an oxidizable metal, a water absorption agent and water and a water-retention layer (12) having a water absorption sheet (102), the exothermic layer (11) and the water-retention layer (12) are in layers, in which the mass ratio of the content of the water absorption agent is from 0.3 to 20 parts by mass for 100 parts by mass of the oxidizable metal, mass ratio of content of water to the content of the water absorption agent in the exothermic layer (11) (water/water absorption agent) is from 0.8 to 13, and the content of water contained in the water-retention layer (12) is from 10 to 45 mass % of the maximum water absorption of said water-retention layer (12).

The present invention relates to a new cryogenic composition intended for use in heat treatment devices, as well as its preparation method. The invention also relates to a heat 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 procedure. The invention finds application in the therapeutic and/or medical field, but also in other fields such as for example for cooling or maintaining foodstuffs or beverages at low temperatures.
