Device for cooling surfaces by evaporation, e.g. bandage for soothing wounded areas by cooling, comprising hydrogel between inner and outer layers, plus separating textile to give dimensional stability

摘要

A cooling device, comprising a chamber (10) with an inner layer (11) for application to a surface to be cooled, an outer layer and a cooling medium (14) (consisting of a hydrogel which is in granular form when dry, binds water and in water-loaded form releases water by evaporation with abstraction of heat) in the chamber between the layers, includes a 3-dimensional separating textile (13) (specifically in knitted or woven form) to provide dimensional stability.
