DE202007004393U1 - Instant cold compress, for acute treatment of injuries, has an inner bag filled with water within an outer bag containing a soluble salt to be mixed by piercing the separation film/membrane for solvation - Google Patents

Abstract

The instant cold compress has an outer bag (1) and an inner bag (2), separated by a film or membrane. The inner bag contains water and the outer bag contains a soluble salt as a compound for solvation with the water. A piercing tool (4) is attached (5) to the interior of the outer bag, for penetration through the film/membrane at a marked point (8). On piercing the inner bag, water mixes with the soluble salt to give an endothermic solvation action. The soluble salt can be nitro chalk, sodium nitrate, sodium chloride, calcium chloride hexahydrate, ammonium thiocyanate, urea or mixtures of at least two components.

Description

The The present invention relates to an instant cooling element, e.g. an instant cold compress with at least a first and a second interior area, wherein the at least first interior area of the at least second interior area through a destructible Foil or membrane is separated and water in one of the interior areas and in the other one in an endothermic solvation process in Water soluble Connection is included.

Sofortkältekompressen find often application, where it concerns the acute treatment of bruises, strains, Strains and compressions and the like goes. It is from particular advantage that instant cold compresses no cooling before use require.

Usually instant cold compresses are like that built that an outer bag a compound soluble in water in an endothermic solvation process contains and further a water-filled inner bag.

outer bag and inner bags are known from the skilled person water-impermeable plastics manufactured, wherein the inner bag is crushable in general, so that the water contained in this after crushing the inner bag in the interior of the instant cold compress or the outer bag pours, in which the compound soluble in water in an endothermic solvation process is included. This causes the mixing of the water with the compound and by the endothermic solution process to cool the Sofortkältekompresse.

Even though Such known from the prior art instant cold compresses are very convenient to handle, they have the disadvantage that activation the compresses are done by pressure. On the one hand, the pressure to Activation should not be too high, hence the activation also safe can be done. On the other hand, the pressure should be as large as possible, so that the compresses (eg during of transport) is not activated inadvertently until intended use become.

task Therefore, it is the instant invention instant cooling elements, in particular instant cold compresses to form so that these are compared with those of the prior art known instant cold compresses have improved properties.

The This object is achieved by an instant cold compress with the features of the attached Protection claim 1 solved.

advantageous Embodiments of the invention are the subject of the protection claims 2/3/4.

According to the invention, it is provided that is soluble in water in an endothermic solvation process Compounds containing interior of the instant cold element at least one suitably shaped body containing the destructible film or membrane of the water bag until deliberate injury The user then sustainably destroyed so that then its content exit and deal with those in an endothermic solvation process soluble in water Mixed compounds.

• 1. Verwendung von hochfesten Folien für den wenigstens einen Innen- und wenigstens einen Außenbeutel welche so zäh und fest sind, dass diese dem üblicherweise angewendeten Druck für die Aktivierung von Sofortkältekompressen mit unter Druck platzendem Innenbeutel auch unter ungünstigen Bedingungen (wie z. B. Fallen bei Transport etc.) standhalten.
• 2. Verwendung von Folien für den wenigstens einen Innen- und den wenigstens einen Außenbeutel, welche eine möglichst hohe Sperre gegen Wasser und Wasserdampf bilden.

To ensure that the instant cold pack can not activate prematurely, it must also be equipped as follows:

• 1. Use of high-strength foils for the at least one inner and at least one outer pouch which are so tough and strong that they are the pressure commonly used for the activation of instant cold compresses with inner bag bursting under pressure even under unfavorable conditions (such as traps with transport etc.) withstand.
• 2. Use of films for the at least one inner and the at least one outer bag, which form the highest possible barrier against water and water vapor.

at of the present invention is generally preferred when the in an endothermic solvation process in water soluble compounds inorganic or organic salts. Here is calcium ammonium nitrate particularly preferred, whereby also sodium nitrate, sodium chloride, calcium chloride hexahydrate, Ammonium thiocyanate, urea or mixtures of at least two the above salts give a corresponding cooling effect. The expert becomes alone on the basis of his knowledge of the cooling effect the different substances when dissolved in water, the respectively on most suitable compound or combination of compounds for the desired one degree of cold and / or the intended use. This is possible easy through research in appropriate tables, books, Internet etc. or simple experimentation.

By the invention becomes an instant cooling element provided only by a deliberately performed injury the film / membrane of the water bag can be activated and against unconsciously performed Activation (such as falling during transport, etc.) as far as possible protected is.

Claims (4)

An instant cold element, in particular a compress, having at least a first and at least a second inner region, wherein the at least first inner region is separated from the at least second inner region by a destructible film or membrane and water in one of these inner regions and one or more in the other in an endothermic solvation process water soluble compounds are included. Furthermore, characterized in that in an endothermic solvation process soluble in water containing suitable compounds containing inner region of the instant cold element contains at least one suitably designed body, which is suitable only with deliberate violation of the destructible shell or membrane of the water bag by the user with this body sustainable so destroying its contents and then mixing with the compounds soluble in water in an endothermic solvation process. Instant cooling element according to claim 1, characterized in that at least one interior of the Instant cooling element of at least one inner bag arranged in an outer bag is formed. Instant cooling element according to claim 2, characterized in that the water in the at least one Inner bag included and this at least one inner bag not easily crushed by hand is. Instant cooling element according to one of the preceding claims, characterized in that in an endothermic solvation process in Water soluble Compounds inorganic or organic salt are, in particular Calcium ammonium nitrate, sodium nitrate, sodium chloride, calcium chloride hexahydrate, Ammonium thiocyanate, urea, or mixtures of at least two the above salts.
