Description

Medizinisches Kühlpad  Medical cooling pad
Die Erfindung bezieht sich auf ein medizinisches Kühlpad zum Kühlen der menschlichen Haut bzw. einer Verletzung auf und/oder unterhalb der Haut. The invention relates to a medical cooling pad for cooling the human skin or an injury on and / or below the skin.
Aus dem Stand der Technik sind medizinische Kühlpads bekannt, die aus einem Kissen mit einer flüssigen, gelartigen, sand- oder erdartigen Füllung bestehen, die eine relativ hohe Wärmekapazität aufweist und möglichst in heruntergekühlter Form auf die Haut aufgelegt und durch eine separate Bandagierung fixiert wird. Das Applizieren des kissenartigen Kühlpads auf die Haut ist umständlich.  Medical cooling pads are known from the prior art, which consist of a cushion with a liquid, gel-like, sand or earth-like filling, which has a relatively high heat capacity and possibly placed in cooled down form on the skin and fixed by a separate bandaging. The application of the pillow-like cooling pads on the skin is cumbersome.
Aus DE 102 60 872 AI und DE 10 2010 038 312 sind Kühlpads bekannt, die selbsthaftend ausgebildet sind, so das zur Fixierung auf der Haut keine weiteren Hilfsmittel und Arbeitsschritte nach dem Auflegen auf die Haut erforderlich sind,  From DE 102 60 872 AI and DE 10 2010 038 312 cooling pads are known, which are designed to be self-adhesive, so that the fixation on the skin no further aids and operations are required after placing on the skin,
Aufgabe der Erfindung ist es, ein medizinisches Kühlpad zu schaffen, das auch bei äußeren Hautverletzungen verwendet werden kann.  The object of the invention is to provide a medical cooling pad that can be used even with external skin injuries.
Das medizinische Kühlpad zum Kühlen der Haut weist einen distalen flexiblen Padträger auf, auf dessen proximale Seite eine flexible Kühlgel- Schicht aufgebracht Ist. Unter„proximal" ist vorliegend stets die der Haut nach der Applikation zugewandte Seite zu verstehen, unter „distal" die nach der Applikation hautabgewandte Seite. Sowohl der Padträger als auch die Kühigel-Schicht sind insoweit flexibel, als dass das Kühlpad sich hierdurch an die räumliche Gestalt der Hautoberfläche anpassen kann. Unter einer Kühlgel-Schicht ist vorliegend jede Art der Beschichtung zu verstehen, die eine passive oder eine aktive Kühlung der Haut ermöglicht. Unter einer Kühlgel-Schicht ist nicht notwendigerweise ein Gel im engeren Sinne zu verstehen, sondern jede Substanz, die kühlend wirken kann und eine gewisse Festigkeit aufweist, also bei Körpertemperatur nicht-fließend ist. The medical cooling pad for cooling the skin has a distal flexible pad carrier, on the proximal side of which a flexible cooling gel layer is applied. The term "proximal" in the present case is always to be understood as the side facing the skin after the application, and "distal" to the side facing away from the skin after application. Both the pad carrier and the cooling gel layer are flexible insofar as the cooling pad can thereby adapt to the spatial shape of the skin surface. In the present case, a cooling gel layer is understood to be any type of coating which enables passive or active cooling of the skin. Under a cooling gel layer is not necessarily a gel in the strict sense to understand, but any substance that can act cooling and has a certain strength, that is non-flowing at body temperature.
Unter einer passiven Kühlung wird die Kühlung durch eine, beispielsweise in einem Kühlschrank, vorgekühlte Kühlgelschicht verstanden, die eine relativ hohe Wärmekapazität aufweist. Unter einer passiven Kühlung wird jedoch auch die Kühlung durch Einlagerung einer Flüssigkeit in die Kühlgelschicht verstanden, wobei die Flüssigkeit nach dem Applizierten auf die Haut verdampft und hierdurch Verdampfungskalte erzeugt. Geeignete Flüssigkeiten hierfür sind Wasser und/oder leicht-flüchtige Flüssigkeiten, wie beispielsweise Menthol, Methylparaben, ätherische Öle etc.  Under a passive cooling, the cooling is understood by a, for example, in a refrigerator, pre-cooled Kühlgelschicht having a relatively high heat capacity. Under a passive cooling, however, the cooling is understood by incorporation of a liquid in the cooling gel layer, wherein the liquid evaporates after the application to the skin and thereby produces evaporative cold. Suitable liquids for this purpose are water and / or volatile liquids, such as, for example, menthol, methylparaben, essential oils, etc.
Typische Produktbeispiele hierfür sind bekannt unter den Bezeichnungen SOS Kinder-Fieber-Pflaster der Dr. Kleine Pharma GmbH, Deutschland, Perskindol Cool Patch oder Sportusal Cool Patch.  Typical product examples for this are known under the designations SOS Children's Fever Plaster of Dr. Ing. Small Pharma GmbH, Germany, Perskindol Cool Patch or Sportusal Cool Patch.
Auf der proximalen Seite der Kühlgel-Schicht ist eine medizinische Wundauflage angeordnet, die eine geringere Fläche aufweist als die Kühlgel-Schicht. Die Wundauflage deckt also nur einen Teil der Kühlgel- Schicht ab, ist also kleiner als die Kühlgel-Schicht. Die Wundauflage kann mittelbar oder unmittelbar mit der Kühlgel-Schicht verbunden sein. Die medizinische Wundauflage besteht aus einem saugfähigen Material, das Feuchtigkeit, insbesondere Wundsekrete und Blut, absorbieren kann. Die Wundauflage kann ferner Substanzen enthalten, die desinfizierend wirken und/oder auf andere Weise medizinisch auf die Wunde einwirken.  On the proximal side of the cooling gel layer, a medical wound dressing is arranged, which has a smaller area than the cooling gel layer. The wound dressing thus covers only a part of the cooling gel layer, ie it is smaller than the cooling gel layer. The wound dressing may be directly or indirectly connected to the cooling gel layer. The medical wound dressing consists of an absorbent material that can absorb moisture, especially wound secretions and blood. The wound dressing may also contain substances which have a disinfecting effect and / or otherwise act medically on the wound.
Damit ist ein medizinisches Kühlpad geschaffen, das auch bei Hautverletzungen eingesetzt werden kann. Das Kühlpad wird hierzu so auf der Hautwunde platziert, dass die Wundauflage über bzw. auf der Hautverletzung zum Liegen kommt. Die Kühlgel-Schicht des Kühlpads sorgt gleichzeitig für eine Kühlung insbesondere der gesamten Zone um die Hautverletzung herum. Die Kühlgel-Schicht liegt jedoch nicht unmittelbar auf der Hautwunde auf. Mit einem einzigen Handgriff kann also sowohl die Hautverletzung versorgt werden als auch ein Haut- Kühlmittel appliziert werden. Vorzugsweise ist die medizinische Wundauflage lateral vollständig umgeben von der Kühlgel-Schicht, bildet also eine gewissermaßen auf der Kühlgel-Schicht schwimmende Insel, Auf diese Weise wird sichergestellt, dass nach Applizieren des Kühlpads die betreffende Hautverletzungs-Zone über ihrem gesamten Umfang durch die Kühlgel-Schicht gekühlt wird. This creates a medical cooling pad that can also be used for skin injuries. The cooling pad is placed on the skin wound so that the wound dressing over or on the skin injury comes to rest. At the same time, the cooling gel layer of the cooling pad ensures cooling, in particular of the entire zone around the skin injury. However, the cooling gel layer does not lie directly on the skin wound. Thus, both the skin injury can be supplied with a single handle and a skin coolant can be applied. Preferably, the medical wound dressing is laterally completely surrounded by the cooling gel layer, thus forming a quasi-floating island on the cooling gel layer. In this way, it is ensured that, after the cooling pad has been applied, the relevant skin injury zone is covered by the cooling gel over its entire circumference. Layer is cooled.
Gemäß einer bevorzugten Ausgestaltung wird die Wundauflage von einem separaten Klebeband getragen, dessen Fläche kielner als die Fläche der Kühlgel-Schicht und größer als die Fläche der Wundauflage ist, Das Klebeband weist auf seiner proximalen Seite eine Kleberschicht auf, die teilweise von der medizinischen Wundauflage verdeckt ist. In diesem Bereich klebt die Wundauflage unmittelbar an dem Klebeband. Die medizinische Wundauflage und das Klebeband bilden also ein klassisches Heftpflaster, das mit seiner distalen Seite wiederum an der Kühlgel-Schicht fixiert ist.  According to a preferred embodiment, the wound dressing is supported by a separate adhesive tape whose surface is keelner than the surface of the cooling gel layer and larger than the area of the wound dressing. The adhesive tape has an adhesive layer on its proximal side, which is partially covered by the medical wound dressing is. In this area, the wound dressing sticks directly to the adhesive tape. The medical wound dressing and the adhesive tape thus form a classic adhesive plaster, which is in turn fixed to the cooling gel layer with its distal side.
Vorzugsweise ist die Kühlgel-Schicht in Bezug auf menschliche Haut selbsthaftend ausgebildet. Das medizinische Kühlpad kann also auf einfache Weise auf die betreffende Hautverletzung aufgelegt werden, und haftet dort ohne eine Bandage oder ohne zusätzliche Haft- oder Klebemittel. Preferably, the cooling gel layer is self-adhesive with respect to human skin. The medical cooling pad can thus be easily applied to the relevant skin injury, and adheres there without a bandage or without additional adhesive or adhesive.
Typische Produktbeispiele hierfür sind bekannt unter den Bezeichnungen SOS Kinder-Fieber-Pflaster der Dr. Kleine Pharma GmbH, Deutschland, Perskindol Cool Patch oder Sportusal Cool Patch. Typical product examples for this are known under the designations SOS Children's Fever Plaster of Dr. Ing. Small Pharma GmbH, Germany, Perskindol Cool Patch or Sportusal Cool Patch.
Vorzugsweise weist die Kleberschicht des Klebebands auf der Haut eine größere Haftkraft auf als die Kühlgel-Schicht auf der distalen Seite des Klebebands. Nachdem die Kühlwirkung der Kühlgel-Schicht erschöpft ist, kann der Padträger mit der daran unverlierbar fixierten Kühlgel-Schicht von der Haut abgezogen werden. Da die Haftkraft der Klebeband- Kleberschicht auf der Haut größer ist als die Haftkraft zwischen der Kühlgel-Schicht und dem Klebeband, verbleibt beim und nach dem Abziehen des Padträgers von der Haut das applizierte Klebeband einschließlich der von ihm gehaltenen Wundauflage auf der Haut. Nach Entfernung des für die Kühlwirkung verantwortlichen Teils des Kühlpads verbleibt das Heftpflaster also auf der Wunde, die zu diesem Zeitpunkt nicht neu versorgt werden muss. Preferably, the adhesive layer of the adhesive tape on the skin has a greater adhesive force than the cooling gel layer on the distal side of the adhesive tape. After the cooling effect of the cooling gel layer is exhausted, the pad carrier with the captive fixed cooling gel layer can be removed from the skin. Since the adhesive force of the adhesive tape adhesive layer on the skin is greater than the adhesive force between the cooling gel layer and the adhesive tape, the applied adhesive tape, including the wound dressing held by it, remains on the skin during and after removal of the pad backing from the skin. To Removal of the responsible for the cooling effect part of the cooling pad so the adhesive plaster remains on the wound, which does not need to be re-supplied at this time.
Vorzugswelse ist proximal der Wundauflage mindestens ein abziehbarer Kühlpad-Schutzstreifen vorgesehen, der die gesamte freiliegende Kühlgel- Schicht unmittelbar bedeckt und schützt. Der Kühlpad-Schutzstreifen schützt zum Einen die Kühlgel-Schicht vor der Austrocknung und schützt zum Anderen die medizinische Wundauflage vor Verschmutzung. Der Kühlpad-Schutzstreifen wird unmittelbar vor der Applizierung des medizinischen Kühlpads vollständig von der proximalen Seite des Kühlpads abgezogen.  Vorzugswelse at least one peelable cooling pad protective strip is provided proximal to the wound dressing, which covers and protects the entire exposed Kühlgel- layer directly. On the one hand, the cooling pad protection strip protects the cooling gel layer from drying out and, on the other hand, protects the medical wound dressing against contamination. The cooling pad protection strip is completely removed immediately before the application of the medical cooling pad from the proximal side of the cooling pad.
Ein Kühlpad mit einem Schutzstreifen ist ebenfalls aus den oben genannten Produkten bekannt.  A cooling pad with a protective strip is also known from the above-mentioned products.
Ferner kann alternativ oder ergänzend zu dem Kühlpad-Schutzstreifen ein Wundauflage-Schutzstreifen vorgesehen sein, der ausschließlich die Wundauflage und, soweit vorhanden, die Klebe rschicht-Selte des Klebebandes unmittelbar bedeckt und schützt. Der Wundauflage- Schutzstreifen bedeckt jedoch nicht die Kühlgel-Schicht lateral der Wundauflage bzw. des Klebebands. Der Wundauflage-Schutzstreifen schützt insbesondere die Wundauflage sowie gegebenenfalls die Kleberschicht des Klebebandes vor Verschmutzung.  Furthermore, as an alternative or in addition to the cooling pad protective strip, a wound protection strip may be provided which exclusively covers and protects the wound dressing and, if present, the adhesive layer-rare of the adhesive tape. However, the wound dressing protective tape does not cover the cooling gel layer laterally of the wound dressing or adhesive tape. In particular, the wound-dressing protective strip protects the wound dressing and optionally the adhesive layer of the adhesive tape from contamination.
Die Schutzstreifen zeichnen sich jeweils dadurch aus, dass sie zusammen mit der Kleberschicht bzw. mit der Kühlgel-Schicht nur eine relativ schwache Haftkraft zulassen, so dass der Kühlpad-Schutzstreifen und/oder der Wundauflage-Schutzstreifen leicht abziehbar bzw. entfern bar ist bzw. sind.  The protective strips are each characterized in that they allow only a relatively weak adhesive force together with the adhesive layer or with the cooling gel layer, so that the cooling pad protective strip and / or the wound dressing protective strip is easily removable or removable bar or are.
Vorzugsweise ist die Kühlgel-Schicht passivkühlend ausgebildet. Hierzu weist die Kühlgel-Schicht insbesondere Stoffe auf, die eine hohe Wärmekapazität aufweisen und/oder eine gewisse Verdunstungskälte erzeugen können. Besonders geeignet sind hierzu wasserbindendePreferably, the cooling gel layer is passively cooled. For this purpose, the cooling gel layer in particular substances that have a high heat capacity and / or a certain evaporation of cold can generate. Particularly suitable for this purpose are water-binding
Substanzen, durch die Wasser bzw. Feuchtigkeit gebunden wird. Substances that bind water or moisture.
Gemäß einer bevorzugten Ausgestaltung der Erfindung weist der Padträger eine Schicht aus einem Traggewebe auf. Der Padträger dient im Wesentlichen der mechanischen Fixierung der Kühlgel-Schicht.  According to a preferred embodiment of the invention, the pad carrier on a layer of a support fabric.

In der Figur 1 ist ein in einem Schutzbeutel 100 verpacktes medizinisches Kühlpad 10 im Längsschnitt dargestellt. Das Kühipad 10 dient der Wundversorgung und Kühlung einer leichteren Hautverletzung. Das medizinische Kühlpad 10 ist vielschichtig aufgebaut. Von distal nach proximal weist das medizinische Kühlpad 10 einen flexiblen Padträger 20 auf, der eine flexible Kühigel-Schicht 30 unverlierbar trägt, auf der wiederum mittig ein bezüglich seiner Fläche kleineres Klebeband 50 mit der kleberfreien Seite haftet, das wiederum auf seiner proximalen Kleberseite ungefähr mittig eine Wundauflage 40 hält, wobei die Klebeband- Kleberschicht 54 und die Wundauflage 40 durch zwei sich mittig überlappende abziehbare Wundauflage-Schutzstreifen 70, 71 abgedeckt sind, und wobei die proximale Seite der Kühlgel-Schicht 30 und der Wundauflage-Schutzstreifen 70, 71 wiederum durch einen einzigen großflächigen Kü h I päd -Sch utzstreif en 60 abgedeckt sind. FIG. 1 shows a longitudinal section of a medical cooling pad 10 packaged in a protective bag 100. The Kühipad 10 is used for wound care and cooling a lighter skin injury. The medical cooling pad 10 has a complex structure. From distal to proximal, the medical cooling pad 10 has a flexible pad carrier 20 which captively supports a flexible cooling layer 30 on which in turn centrally adheres a smaller adhesive tape 50 to the adhesive-free side, which in turn is approximately centered on its proximal adhesive side a wound dressing 40 holds, wherein the adhesive tape adhesive layer 54 and the wound dressing 40 are covered by two centrally overlapping peelable wound dressing protective strips 70, 71, and the proximal side of the cooling gel layer 30 and the wound dressing protection strip 70, 71 again a single large-area Küh äd päd-S utzstreif en 60 are covered.
Der flexible Padträger 20 besteht im Wesentlichen aus einem vliesartigen Traggewebe 22, das distal durch eine wasserundurchlässige Beschichtung The flexible pad carrier 20 consists essentially of a fleece-like support fabric 22, the distal by a water-impermeable coating
24 bedeckt ist. Die wasserundurchlässige Beschichtung 24 kann beispielsweise aus einer geeigneten Kunststoff- Folie bestehen» 24 is covered. The water-impermeable coating 24 may consist of a suitable plastic film, for example »
Das Traggewebe 22 kann ein Viiesmaterial sein, das dem Verbund aus The support fabric 22 may be a Viiesmaterial, the composite of
Padträger 20 und Kühlgel-Schicht 30 eine ausreichende mechanischePad carrier 20 and cooling gel layer 30 a sufficient mechanical
Festigkeit gibt, sich jedoch an die Oberflächen- Form der betreffenden Hautpartie anpassen kann. Strength, but can adapt to the surface shape of the skin area concerned.
Die Kühlgel-Schicht 30 besteht aus einem Kühlgel-Körper 32, der beispielsweise aus einem medizinischen Kühlgel gebildet wird. Die Kühlgel- Schicht 30 ist relativ dick, und kann eine Dicke von bis zu mehreren Millimetern aufweisen. In dem Kühlgel-Körper 32 kann in einer entsprechenden Matrix Wasser, Methanol bzw. Feuchtigkeit eingelagert sein, und können alternativ oder zusätzlich auch andere leicht-flüchtige Flüssigkeiten eingelagert sein. The cooling gel layer 30 consists of a cooling gel body 32, which is formed for example from a medical cooling gel. The cooling gel layer 30 is relatively thick and may have a thickness of up to several millimeters. Water, methanol or moisture may be incorporated in the cooling gel body 32 in a corresponding matrix, and alternatively or additionally, other readily volatile liquids may also be incorporated.
Die Kühlgel-Schicht 30 ist selbsthaftend ausgebildet, weist also eine Haft- Beschichtung oder eine selbsthaftende Eigenschaft auf, die auf der Haut eine gewisse Anhaftung der Kühlgel-Schicht 30 bzw. des medizinischen Kühipads 10 sicherstellt. Ferner sorgt die Hafteigenschaft der Kühlgel- Schicht 30 dafür, dass das Klebeband 50 zentral in Position gehalten wird. Das Klebeband 50 kann ein übliches medizinisches Klebeband aus einer geeigneten Kunststoff-Folie oder einem geeigneten Kunststoff- Gewebe sein, dessen distale Seite nicht-klebend ausgebildet ist und das auf der proximalen Seite eine Kleberschicht 54 aufweist. Das Klebeband 50 ist sowohl in der Längserstreckung als auch In der Quererstreckung kleiner als die Längserstreckung und Quererstreckung der Kühlgel-Schicht 30. The cooling gel layer 30 is designed to be self-adhesive, that is to say it has an adhesive coating or a self-adhesive property which ensures a certain adhesion of the cooling gel layer 30 or of the medical cooling bath 10 on the skin. Further, the adhesive property of the cooling gel layer 30 ensures that the adhesive tape 50 is centrally held in position. The adhesive tape 50 may be a conventional medical adhesive tape made of a suitable plastic film or a suitable plastic fabric, whose distal side is non-adhesive and which has an adhesive layer 54 on the proximal side. The adhesive tape 50 is smaller than the longitudinal extent and transverse extent of the cooling gel layer 30 both in the longitudinal extent and in the transverse extent.
Auf das Klebeband 50 ist mittig die medizinische Wundauflage 40 aufgeklebt, die von einem saugfähigen, also feuchtigkeitsaufnehmenden medizinischen Vlies 42 oder Gewebe gebildet wird, das aseptische Substanzen aufweist, Das Klebeband 50, und die Wundauflage 40 bilden zusammen ein herkömmliches Heftpflaster 55, wie es beispielsweise unter der Bezeichnung Hansaplast Universal Pflaster Strips bekannt ist. On the tape 50, the medical wound dressing 40 is glued in the middle, which is formed by an absorbent, so moisture-absorbing medical non-woven 42 or tissue having aseptic substances, the adhesive tape 50, and the wound dressing 40 together form a conventional adhesive plaster 55, as for example known as Hansaplast Universal Plaster Strips.
Die proximale Seite des Klebebandes 50 bzw. seine Kleberschicht 54 sowie die Wundauflage 40 sind durch zwei sich überlappende Wundauflage- Schutzstreifen 70,71 aus Kunststoff- Folie abgedeckt, die nur eine relativ kleine Klebekraft mit der Kleberschicht 54 entwickeln, also leicht von der Kleberschicht 54 abziehbar sind. The proximal side of the adhesive tape 50 or its adhesive layer 54 and the wound dressing 40 are covered by two overlapping wound-dressing protective strips 70, 71 made of plastic film, which only develop a relatively small adhesive force with the adhesive layer 54, that is to say slightly from the adhesive layer 54 are removable.
Den proximalen Abschluss des medizinischen Kühlpads 10 bildet schließlich ein vollflächiger Kühlpad- Schutzstreifen 60 aus Kunststoff- Folie, der die Kühlgel-Schicht 30 vollflächig unmittelbar bedeckt und schützt bzw. mittig unmittelbar die beiden Wundauflagen-SchutzstreifenThe proximal end of the medical cooling pad 10 finally forms a full-surface cooling pad protective strip 60 made of plastic film, which covers the cooling gel layer 30 over the entire area immediately and protects or centrally directly the two wound-protective strips
70 bedeckt. 70 covered.
Der Verbund aus Padträger 20, selbstklebender Kühlgel-Schicht 30 und Kühlpad -Schutzstreifen 60 kann, ohne Heftpflaster, unter anderem bezogen werden unter den Produkt-Bezeichnungen SOS Kinder-Fieber- Pfiaster der Dr. Kleine Pharma GmbH, Deutschland, Perskindol Cool Patch oder Sportusal Cool Patch. The composite of pad carrier 20, self-adhesive cooling gel layer 30 and cooling pad protection strip 60 can be obtained, without adhesive plaster, inter alia under the product designations SOS Children's Fever Pfiaster the Dr. med. Small Pharma GmbH, Germany, Perskindol Cool Patch or Sportusal Cool Patch.
Die Vorbereitung bzw. Applizierung des Kühlpads 10 ist sequenziell in den Figuren 1-6 dargestellt: Zunächst wird der Schutzbeutel 100, der die Sterilität des Kühlpads 10 sicherstellt, aufgerissen, und wird das Kühlpad 10 aus dem aufgerissenen Schutzbeutel 100 entnommen, so dass das Kühlpad 10 in der in der Figur 2 dargestellten Ausgangs-Konstitution vorliegt. Anschließend wird, wie in Figur 3 dargestellt, der Kühlpad-Schutzstrelfen 60 vollständig von dem Kühlpad 10 abgezogen. Schließlich werden die nun zugänglichen beiden Wundauflage-Schutzstreifen 70,71 vollständig von dem Klebeband 50 abgezogen so dass, wie in Figur 4 dargestellt, das Kühlpad 10 ' nun bereit zum Applizieren auf der Haut ist. The preparation or application of the cooling pad 10 is shown sequentially in FIGS. 1-6: First of all, the protective bag 100, which ensures the sterility of the cooling pad 10, is torn open, and the cooling pad 10 is removed from the opened protective bag 100, so that the cooling pad 10 is in the starting constitution shown in FIG. Subsequently, as shown in FIG. 3, the cooling pad protection device 60 is completely pulled off the cooling pad 10. Finally, the now accessible two wound protection strips 70,71 are completely removed from the adhesive tape 50 so that, as shown in Figure 4, the cooling pad 10 'is now ready for application to the skin.
Der auf die Haut 8 applizierte Zustand des Kühlpads 10 ' ist in der Figur 5 dargestellt. Hier ist bereits erkennbar, dass im Bereich des Klebebands 50 die Kleberschicht 54 des Klebebandes 50 unmittelbar auf der Haut 8 klebt. Die selbsthaftende Kühlgei-Schicht 30 haftet In allen nicht von dem Klebeband 50 abgedeckten Bereichen direkt und unmittelbar an der Haut 8. The applied to the skin 8 state of the cooling pad 10 'is shown in Figure 5. Here it can already be seen that in the region of the adhesive tape 50, the adhesive layer 54 of the adhesive tape 50 directly adheres to the skin 8. The self-adhesive Kühlgei layer 30 adheres in all not covered by the tape 50 areas directly and directly on the skin. 8
Sobald die Kühlwirkung der Kühlgel-Schicht 30 erschöpft ist, kann der Padträger 20 einschließlich der daran fixierten Kühlgel-Schicht 30 von der Haut 8 abgezogen werden. Da die Haftkraft zwischen der Kühlgel-Schlcht 30 und der distalen nicht-klebenden Seite des Klebebands 50 verhältnismäßig klein ist, reicht die Klebkraft zwischen der Kleberschicht 54 und der Haut 8 aus, damit beim Abziehen des Verbandes aus Padträger 20 und Kühlgel-Schicht 30 das Klebeband 50 einschließlich der Wundaufiage 40 auf der Haut 8 kleben bleibt. Nach dem Abziehen der Kühlgel-Schicht 30 gelangt mehr Luft an die Haut 8, wodurch der Heilprozess begünstigt wird.  As soon as the cooling effect of the cooling gel layer 30 has been exhausted, the pad carrier 20, including the cooling gel layer 30 fixed thereto, can be pulled off the skin 8. Since the adhesive force between the cooling gel slit 30 and the distal non-adhesive side of the adhesive tape 50 is relatively small, the adhesive force between the adhesive layer 54 and the skin 8 is sufficient to allow the pad backing 20 and cooling gel layer 30 to peel off the dressing Adhesive tape 50, including the wound dressing 40, sticks to the skin 8. After removing the cooling gel layer 30 more air reaches the skin 8, whereby the healing process is favored.
