Abstract

A cooling cushion for use in cooling processes, contains a gel forming agent mixed with a salt mixture, and an activator. The agent and the salt mixture are stored separately from the activator in the cushion, until they are brought together.

Description

Die Erfindung betrifft ein Kühlkissen für die Anwendung im medizinischen und touristischen Bereich, im Bereich der Wandertouristik und des Campings, Veranstaltungen im Freien sowie anderer mit dem Erfordernis einer spontaner Kühlung begleitender Anwendungsgebiete, mit dem bei der erstmaligen Anwendung der jeweilige vorgesehene Kühlvorgang spontan ausgelöst werden kann und bei nachfolgenden Anwendungen des Kühlkissens wie bei Kühlkissen des Standes der Technik zwecks Aufladung dieses extern gekühlt wird. So wird nach dem DE 29 81 1496 U 1 ein Getränkebehälter mit einem internem Kühlmittel beschrieben, mit dem ohne Vorkühlung und ohne die Verwendung von isolierten Transportbehältern direkt vor Ort, ohne externe Hilfsmittel zum Augenblick des Verzehrs, allerorts gekühlt werden kann. Da bei diesen Gelegenheiten nicht immer die Möglichkeit einer Kühlung der Getränke vorhanden ist, bedarf es für den Transport die Anwendung von Kühltaschen o. ä. Zwecks Erreichung der Kühlung ist der Getränkebehälter mit einem internen Reaktionsmittelbehälter ausgestattet. Durch den Verbraucher wird der Reaktionsmittelbehälter mittels einer Vorrichtung aktiviert. Dadurch findet eine Reaktion der Komponenten Salz mit Wasser statt, deren chemische Vereinigung zum Kühlmittel wird. Nachteilig an diesem Getränkebehälter ist, die nur einmalig mögliche Anwendung der Einrichtung. Bekannt sind auch Kühlkissen, die nur für eine einmalige Anwendung geeignet sind. Die Aufgabe der Erfindung besteht deshalb in der Schaffung einer Einrichtung, insbesondere eines Gelkissens, das zur anfänglichen unabhängig von einer externen Vorbehandlung einmaligen Anwendung geeignet ist und zudem die Voraussetzungen für eine wiederholte Aufbereitung besitzt.The invention relates to a cooling pillow for use in medical and tourist Area, in the field of hiking tourism and camping, outdoor events as well other areas of application accompanying the requirement of spontaneous cooling, with the intended cooling process when used for the first time spontaneously can be triggered and in subsequent applications of the cooling pad as in Cooling bags of the prior art for the purpose of charging them are cooled externally. So will according to DE 29 81 1496 U 1, a beverage container with an internal coolant described with the without pre-cooling and without the use of insulated Transport containers directly on site, without external aids at the moment of consumption, can be cooled everywhere. Because on these occasions not always the possibility cooling of the drinks is available, the use of for transport is required Cooling bags or similar. To achieve cooling, the beverage container is marked with a internal reagent container. The consumer will Reactant container activated by means of a device. This causes a reaction from the Components salt with water instead, whose chemical association becomes the coolant. A disadvantage of this beverage container is the only one-time use of the Facility. Also known are cooling cushions that are only suitable for one-time use are. The object of the invention is therefore to create a device especially a gel pad that is initially independent of an external one Pretreatment single use is suitable and also the prerequisites for one repeated processing.

Gelöst wird diese Aufgabe durch die Merkmale des Anspruches 1. Vorteilhafte Weiterbildungen des Kühlkissens werden durch die Ansprüche 2-8 beschrieben.This problem is solved by the features of claim 1. Advantageous Developments of the cooling pad are described by claims 2-8.

Das erfindungsgemäße Kühlkissen soll nachfolgend anhand eines Ausführungsbeispieles näher erläutert werden. Innerhalb des Kühlkissens befindet sich ein Salzgemisch aus Ammoniumnitrat und einen aus Methylcellulose - Natrium bestehendem Gelbildner. Der Gelbildner wird mit dem Ammoniumnitrat verrieben bis ein homogenes, feinkristallines Salzgemisch entsteht. Desweiteren beinhaltet das Gelkissen einen Aktivator, der aus einem Gemisch aus Wasser und Lebensmittelfarbe besteht. Wasser und Lebensmittelfarbe werden in ein Folientütchen abgefüllt, das Folientütchen verschweißt und zusammen mit dem Salzgemisch in das Kühlkissen eingeschweißt. An Stelle des Ammoniumnitrates kann sich im Inneren des Kühlkissens auch eine Kältemischung, wie z. B. Mischungen aus Salzen oder Trockeneis mit Wasser, Eis oder organischen Flüssigkeiten, die sich bei ihrer Zusammenführung abkühlen, befinden. Durch äußeren mechanischen Druck auf den Aktivator wird dieser zerstört und durch die Vermischung mit den im Kühlkissen vorhandenen Substanzen kommt es zur Kältereaktion. Der Umgebung wird Wärmeenergie entzogen und die Temperatur des Kältekissens sinkt auf ca. Null Grad Celsius ab. Durch Hinzufügen von geeigneten gefrierpunktherabsetzenden Zusätzen bleibt die Viskosität des Kältekissens auch bei ca. 18 Grad Celsius (Gefrierschranktemperatur) erhalten. Nach der erstmaligen Nutzung entsteht nach ca. 24 Stunden ein blaues, klares, homogenes, hochviskoses Gel. Dieses Kühlkissen kann jetzt wie an sich bekannte Kühlgelkissen extern gekühlt werden und steht für weitere Anwendungen zur Verfügung.The cooling pad according to the invention is intended to be described below using an exemplary embodiment are explained in more detail. There is a salt mixture inside the cooling pad Ammonium nitrate and a gelling agent consisting of methyl cellulose sodium. The Gelling agent is triturated with the ammonium nitrate until a homogeneous, fine crystalline Salt mixture is formed. Furthermore, the gel cushion contains an activator that consists of a Mixture of water and food coloring consists. Water and food coloring are in filled a foil sachet, the foil sachet sealed and together with the Salt mixture welded into the cooling pad. Instead of ammonium nitrate inside the cooling pad also a cold mixture, such as B. mixtures of salts or  Dry ice with water, ice or organic liquids that are present in your Cool, merge. By external mechanical pressure on the Activator is destroyed and by mixing with those in the cooling pad existing substances cause a cold reaction. The environment becomes thermal energy withdrawn and the temperature of the cold cushion drops to approximately zero degrees Celsius. By Adding suitable freezing point reducing additives will keep the viscosity of the Keep the cold pillow at around 18 degrees Celsius (freezer temperature). After first-time use, a blue, clear, homogeneous, highly viscous gel. This cooling pad can now be used externally as is known as a cooling gel pad be cooled and is available for other applications.
