Description

Mehrschichtiges Saugkissen Die Erfindung betrifft ein mehrschichtiges Saugkissen, das eine relativ große Fähigkeit zur Flüssigkeitsaufnahme besitzt. Multilayer Absorbent Pad The invention relates to a multilayer absorbent pad Absorbent pad that has a relatively large ability to absorb liquids.

Saugkissen sind schon bekannt. Sie werden vor allem zum Absorbieren und Fernhalten von Flüssigkeiten und Ausscheidungen des ienschlichen Körpers benötigt. So werden Saugkissen als Windeln, Monatsbinden und Wundverbände verwendet.Absorbent pads are already known. They are mainly used to absorb and keeping away fluids and exudates from the human body. Absorbent pads are used as diapers, sanitary napkins and wound dressings.

Bisher sind Saugkissen häufig aus Geweben von Garnen pflanzlicher oder tierischer Fasern, beispielweise Baumwollgeweben, hergestellt worden. Gelegentlich sind Jedoch auch nicht gewebte Materialien aus Zellulose- oder anderen organischen Fasern zur Herstellung derartiger Kissen verwendet worden. Die nicht gewebten Materialien sind nicht nur billiger in der Herstellung als Gewebe, sondern sie sind vor allem in Wasser löslich. Aus derartigen nicht gewebten Materialien hergestellte Saugkissen sind daher besonders für eine einmalige Benutzung und anschliessende Beseitigung geeignet.So far, absorbent pads have often been made from woven fabrics of vegetable yarns or animal fibers, for example cotton fabrics. Occasionally However, there are also non-woven materials made of cellulose or other organic materials Fibers used to make such pillows been. the non-woven materials are not only cheaper to manufacture than woven fabrics, rather, they are mainly soluble in water. Made of such non-woven materials Manufactured absorbent pads are therefore particularly suitable for a single use and subsequent use Elimination suitable.

Gewöhnlich verteilt sich jedoch bei aus nicht gewebten Materialien hergestellten Saugkissen die absorbierte Flüssigkeit nicht gleichmäßig Uber dessen gesamtes Volumen. Die Flüssigkeit durchdringt daher einen Teil des Kissens bevor die übrigen Teile benetzt worden sind. Hierdurch ergeben sich nicht nur Unannehmlichkeiten bei der Anwendung, sondern es werden auch die nicht benetzten Teile des Saugkissens ungenügend ausgenutzt.However, it usually spreads when made of non-woven materials The absorbed liquid is not evenly distributed over the absorbent pad entire volume. The liquid therefore penetrates part of the pillow before the remaining parts have been wetted. This not only creates inconvenience during application, but also the non-wetted parts of the absorbent pad insufficiently exploited.

Das Saugkissen gemäß der vorliegenden Erfindung vermeidet weitgehend diese Nachteile. Es ist gekennzeichnet, durch zwei aufeinanderliegende flüssigkeitsabsorbierende Schichten, bei denen die Oberseite der ersten, die derjenigen der zweiten gegenüberliegt, eine kleinere Fläche als diese aufweist, durch eine zwischen beiden absorbierenden Schichten liegende, Flüssigkeiten einen Widerstand entgegensetzende Zwischenschicht, deren der Oberseite der zweiten absorbierenden Schicht gegenüberliegende Oberseite eine kleinere Fläche als diese aufweist, sowie durch eine derartige Ausbildung, daß es mit der eraten absorbierenden Schicht zum Körper des Anwenders hin zu benutzen ist, so daß Flüssigkeit, die in und durch die erste absorbierende Schicht hindurch und danach an die Zwischenschicht gelangt, über deren Ränder hinweg in die zweite absorbierende Schicht hineinfließt.The absorbent pad according to the present invention largely avoids these disadvantages. It is characterized by two superposed liquid-absorbent Layers in which the top of the first opposite that of the second has a smaller area than this, by an absorbent between the two Intermediate layer lying in layers and resisting liquids, its top side opposite the top side of the second absorbent layer has a smaller area than this, as well as by such a design, that it can be used with the appropriate absorbent layer facing towards the body of the user is so that liquid in and through the first absorbent layer and then reaches the intermediate layer, over its edges into the second absorbent layer flows into it.

Die Oberseiten der isolierenden Zwischenschicht, die den absorbierenden Schichten gegenüberliegen, weisen vorzugsweise annähernd dieselbe Fläche und dieselben Abmessungen wie die der Oberseite der ersten absorbierenden Schicht gegenüberliegende Oberseite der zweiten absorbierenden Schicht auf.The tops of the insulating intermediate layer that form the absorbent Layers facing each other preferably have approximately the same area and the same Dimensions like that of the top of the first absorbent layer opposite top of the second absorbent layer.

Gemäß einer bevorzugten Ausführungsform der Erfindung weist das Saugkissen ausserdem eine flüssigkeitsverteilende Schicht auf, die zwischen der zweiten absorbierenden Schicht und der isolierenden Zwischenschicht angeordnet ist und deren den Oberseiten der zweiten absorbierenden Schicht und der isolierenden Zwischenschicht gegenüberliegende Oberseiten beide annähernd dieselbe Pläche und dieselben Abmessungen wie de gegenüberliegende Oberseite der zweiten absorbierenden Schicht aufweisen, so daß diese Verteilerschicht die über die Ränder der isolierenden Zwischenschicht eindringende Flüssigkeit im wesentlichen gleichmäßig über die gegenüberliegende Oberseite der zweiten absorbierenden Schicht verteilt.According to a preferred embodiment of the invention, the absorbent pad also has a liquid-distributing layer between the second absorbent Layer and the insulating intermediate layer is arranged and the upper sides thereof the second absorbent layer and the insulating intermediate layer opposite Upper sides both approximately the same area and the same dimensions as the opposite Have upper side of the second absorbent layer, so that this distribution layer the liquid penetrating over the edges of the insulating intermediate layer in the substantially evenly across the opposite top of the second absorbent Layer distributed.

Das Saugkissen gemäß der Erfindung stellt daher ein Mehrschichtsaugkissen dar, das eine große Fähigkeit zur Flüssigkeitsaufnahme aufweist und bei des alle Teile benetzt werden bevor die Flüssigkeit einen Teil ganz durchdrungen hat.The absorbent pad according to the invention therefore constitutes a multilayer absorbent pad which has a great ability to absorb fluids and everything Parts are wetted before the liquid has completely penetrated a part.

Diese und andere Eigenschaften der Erfindung werden im folgenden anhand der Beschreibung unter Bezugnahme auf zwei Figuren näher erläutert, von denen die Fig. 1 eine Aufsicht eines bevorzugten Ausführungsbeispieles des erfindungsgemäßen ßaugkissens und die Fig. 2 einen Querschnitt längs der Linie 2-2 der Fig. 1 zeigt.These and other features of the invention will be discussed hereinafter the description with reference to two figures explained in more detail, of which the Fig. 1 is a plan view of a preferred embodiment of the invention suction pad and FIG. 2 shows a cross section along the line 2-2 of FIG.

Das erfindungsgemäße Saugkissen ist in den Figuren, in denen eine bevorzugte Ausführungsform desselben dargestellt ist, mit 10 bezeichnet. Saigkissen 10 enthält eine Mehrzahl übereinander gelegter Schichten, die vorzugsweise alle in Wasser auflösbar sind undzu denen eine erste und eine zweite absorbierende Schicht 12 und 14 gehören. Das Saugkissen 10 ist so ausgestaltet, daß es mit der Schicht 12 zum Körper eines Anwenders hin zu be nutzen ist. Im folgenden wird zur Vereinfachung der Erläuterungen diese Seite als die Innenseite und die bei Anwendung dem Körper des Anwenders abgewendete Seite als Aussenseite bezeichnet. In entsprechender Weise werden die Verhältnisse der übrigen einzelnen Schichten des Saugkissens 10 beschrieben.The absorbent pad according to the invention is shown in the figures in which a preferred embodiment of the same is shown, denoted by 10. Saig pillow 10 includes a plurality of superimposed layers, preferably all of them in water are resolvable and to which a first and a second absorbent layer 12 and 14 include. The suction pad 10 is designed so that it is to be used with the layer 12 towards the body of a user. Hereinafter For convenience of explanation this page is called the inside and the when used, the side facing away from the user's body is referred to as the outside. The proportions of the other individual layers are similar of the suction pad 10 described.

Die Lagen 12 und 14 enthalten nicht gewebte Streifen flüssigkeitsabsorbierenden Materials wie z.B. Zellulesefasern, und/oder organische nichtzellulosartige Teile und/oder Fasern, wie sie in den US-Patenten 3 347 236 und 3 070-095 offenbart sind. Wie in diesen Patenten angegeben ist, sind derartige organsiche nichtzelluloseartige Teilchen und/oder Fasern solche, die aus einer Gruppe ausgewählt sind, zu der Bluteiweiß, Hühnereiweiß, Stärke, Pektin, algin, Tragant- und Guargummi, natürlicher und synthesischer Gummi, auf Polysaccharidbasis aufgebaute Gummisorten, chemisch veränderte Stärkearten und chemisch veränderte auf Polysaccharid beruhende Gummi sorten gehören. Ähnlich wie viele Zellstoffe sind solche nichtzellulosearte Stoffe sowohl flüssigkeitsabsorbierend als auch im trockenen und im feuchten Zustand unschädlich fur den Körper. Die Schichten 12 und 14 haben rechteckige Gestalt und weisen etwa dieselbe Länge auf. Die Schicht 12 ist jedoch schmaler als die Schicht 14, so daß die Außenfläche der Schicht 12 kleiner als die Innenfläche der Schicht 14 ist, was bedeutet, daß die Oberfläche der Schicht 12, die einer Oberfläche der Schicht 14 gegenüberliegt kleiner ist als diese. Die Schicht 12 ist in Querrichtung mittig auf der Schicht 14 angeordnet, Das Saugkissen 10 enthält außerdem eine zwischen den Schcihten 12 und 14 angeordnete Schicht 16, die für Flüssigkeiten einen großen Widerstand darstELLT: Sie kann eine flüssigkeitsundurch lässige Folie enthalten, besonders günstig ist jedoch eine luftdurchlässige und im wesentlichen flüssigkeitsundurchlässige Folie, wobei mit flüssigkeitsundurchlässig gemeint ist, daß ein Durchdringen der Flüssigkeit erst nach einer Zeitspanne von mehr als einigen Sekunden, beispielsweise 1-5 Minuten, ständigen ausgesetztseins erfolgt. Solche Folien können nicht gewebte Folien aus Zellulosefasern, die eine flüssigkeitsabstoßende Deckschicht, z.B. eine Latexschicht, eine Lackschicht oder eine aus einer aufgeschäumten organischen Suspension bestehende Schicht aufweisen, oder perforierte Plastikfolien sein.The layers 12 and 14 contain nonwoven strips of liquid absorbent Material such as cellulosic fibers, and / or organic non-cellulosic parts and / or fibers as disclosed in U.S. Patents 3,347,236 and 3,070-095. As indicated in these patents, such organic are non-cellulosic Particles and / or fibers those selected from a group to which blood protein, Chicken protein, starch, pectin, algin, tragacanth and guar gum, more natural and synthetic Rubber, types of rubber based on polysaccharides, chemically modified types of starch and chemically modified polysaccharide-based gums. Similar like many pulps, such non-cellulosic fabrics are both liquid-absorbent as well as harmless to the body when dry and when wet. The layers 12 and 14 are rectangular in shape and have approximately the same length. The layer However, 12 is narrower than layer 14, so that the outer surface of layer 12 is smaller than the inner surface of layer 14, which means that the surface of the layer 12, which is opposite to a surface of the layer 14, is smaller than these. The layer 12 is arranged in the transverse direction centrally on the layer 14, The absorbent pad 10 also includes one disposed between the layers 12 and 14 Layer 16, which presents a great resistance to liquids: it can be liquid impermeable contain casual film, is particularly cheap however, an air-permeable and essentially liquid-impermeable film, whereby by liquid-impermeable is meant that a penetration of the liquid only after a period of more than a few seconds, e.g. 1-5 minutes, constant exposure occurs. Such films can be made from non-woven films Cellulose fibers that have a liquid-repellent cover layer, e.g. a latex layer, a layer of lacquer or one consisting of a foamed organic suspension Have a layer, or be perforated plastic sheets.

Länge und Breite der Schicht 16 sind kleiner als diejenigen der Schicht 14, so daß die inneren und äusseren Oberflächen der Schicht 16 jeweils eine kleinere Fläche als die innere Oberfläche der Schicht 14 aufweisen, was bedeutet, daß die den Schichten 12 und 14 gegenüberliegenden Oberflächen der Schicht 16 kleiner sind als die Oberfläche der Schicht 14, die derjenigen der Schicht 12 gegenüberliegt. Länge und Breite der Schicht 16 sind annähernd gleich groß wie bei Schicht 12, so daß ihre innere und ihre äussere Oberfläche jeweils annähernd gleich groß wie die äussere Oberfläche der Schicht 12 sind, was bedeutet, daß die den Schichten 12 und 14 gegenüberliegenden Oberflächen der Schicht 16 annähernd dieselbe Größe und Abmessung wie die der Oberfläche der Schicht 14 gegenüberliegende Oberfläche der Schicht 12 aufweist.The length and width of the layer 16 are smaller than those of the layer 14, so that the inner and outer surfaces of the layer 16 each have a smaller one Area than the inner surface of the layer 14, which means that the surfaces of layer 16 opposite layers 12 and 14 are smaller than the surface of layer 14 opposite that of layer 12. The length and width of layer 16 are approximately the same as for layer 12, see above that their inner and their outer surface are each approximately the same size as the outer surface of the layer 12 are, which means that the layers 12 and 14 opposite surfaces of the layer 16 are approximately the same size and dimension like the surface of layer 12 opposite the surface of layer 14 having.

Das Saugkissen 10 enthält ausserdem eine der Flüssigkeitsverteilung dienende Schicht 18, die zwischen der äusseren absorbierenden Schicht 14 und der für Flüssigkeiten schwer durchlässigen Schicht 16 liegt. Die Schicht 18 enthält ein nichtbewebtes Band aus Material, das eine merklich höhere Kapillarität als das Material aufweist, aus dem die Schichten 12 und 14 bestehen, es kann also beispielsweise ein kreppartigen Band aus Zellulosefasern sein. Länge und Breite der Schicht 18 sind annähernd dieselben wie bei der Schicht 14, so daß die innere und äussere Oberfläche der Schicht 18 jeweils dieselbe Fläche wie die innere Oberfläche der Schicht 14 aufweisen, mit anderen Worten, die Oberflächen der Schicht 18, die den Schichten 14 und 16 gegenüberliegen, weisen jeweils dieselbe Fläche und Abmessungen auf, wie die der Schicht 12 gegenüberliegende Oberfläche der Schicht 14.The absorbent pad 10 also contains a liquid distributor serving layer 18, which is between the outer absorbent layer 14 and the layer 16, which is difficult to pass through liquids, is located. The layer 18 contains a non-woven tape of material that has a noticeably higher capillarity than that Has material from which the layers 12 and 14 are made, so it can for example be a crepe tape made of cellulose fibers. Length and width of layer 18 are approximately the same as for layer 14, so that the inner and outer surface of layer 18 each have the same area as the inner surface of layer 14, in other words, the surfaces of layer 18 which facing layers 14 and 16, each have the same area and dimensions on, like the surface of the layer 14 opposite the layer 12.

Zusätzlich weist das Saugkissen 10 einen Überzug 20 auf, der um die absorbierenden Schichten 12 und d 14 angebracht ist, und der einen Innenteil 22 und einen Aussenteil 24 aufweist. Die Teile 22 und 24 des Überzuges halten die verschiedenen Schichten des Saugkissens 10 im zusammengesetzten Zustand zusammen.In addition, the absorbent pad 10 has a cover 20 that extends around the absorbent layers 12 and 14 is attached, and the one inner part 22 and an outer part 24. Parts 22 and 24 of the cover hold the various ones Layers of the absorbent pad 10 together in the assembled state.

Der äussere Teil 24 liegt auf der äusseren Oberfläche der ab sorbierenden Schicht 14 auf und hat etwa dieselbe Länge und Breite wie diese. Ähnlich wie die großen Flüssigkeitswiderstand aufweisende Schicht 16 kann dieser äussere Teil 14 flüssigkeitsundurchlässiges bandförmiges Material enthalten, vorzugsweise enthält er aber luftdurchlässiges und annährend flüssigkeitsundurchlässiges flexibles bandförmiges Material.The outer part 24 lies on the outer surface of the absorbent Layer 14 and has about the same length and width as this. Similar to that Layer 16 exhibiting high fluid resistance can be this outer part 14 contain liquid-impermeable tape-shaped material, preferably contains but he air-permeable and almost liquid-impermeable flexible band-shaped Material.

Der innere Teil 22 liegt auf der inneren Oberfläche der absorbierenden Schicht 12 auf und erstreckt sich bis über die Ränder der äusseren Oberfläche der absorbierenden Schicht 14 und des äusseren Teils 24 des Überzeuges 20. Die Ränder des Teils 22 sind über diejenigen des Teild 24 umgeschlagen und an dessen äusserer Oberfläche in einer geeigneten Weise befestigt, z.B. durch Ankleben oder durch Anschmelzen. Der innere Teil 22 enthält flüssigkeitsundurchlässigen nicht gewebtes bandförmiges Material, das keine Feuchtigkeit annimmt, wie z.B. bandförmiges Material aus Rayonfasern.The inner portion 22 lies on the inner surface of the absorbent Layer 12 and extends over the edges of the outer surface of the absorbent layer 14 and the outer part 24 of the convex 20. The edges of part 22 are folded over those of part 24 and on its outer side Surface attached in a suitable way, e.g. by gluing or by melting. The inner part 22 comprises liquid impervious non-woven tape-shaped Material that does not absorb moisture, such as ribbon-shaped material made of rayon fibers.

Das Saugkissen 10 weist ausserdem noch eine zweite der Flüssigkeitsverteilung dienende Schicht 26 auf, die zwischen der inneren Oberfläche der absorbierenden Schicht 12 und dem Teil 22 des Überzuges angeordnet ist. Ähnlich wie die Schicht 18 enthält auch die Schicht 26 nicht gewebtes bandförmiges Material, das eine merklich höhere Kapillarität als das Material aufweist, aus dem die absorbierenden Schichten 12 und 14 bestehen, beispielsweise kreppartiges bandförmiges Material aus Zellulosefasern. Länge und Breite der Schicht 26 sind annährend gleich groß wie bei der Schicht 12, so daß die innere und äussere Oberfläche der Schicht 26 annähernd dieselbe Fläche wie die innere Oberfläche der Schicht 12 aufweisen, d.h. die Oberflächen der Schicht 26, die der Schicht 12 und dem Teil 22 des überzuges gegenüberliegen, weisen Jeweils annähernd dieselbe Fläche und dieselben Abmessungen wie die dem Teil 22 gegenüberliegende Oberfläche der Schicht 12 auf.The absorbent pad 10 also has a second one for distributing the liquid serving layer 26, which is between the inner surface of the absorbent layer 12 and the part 22 of the cover is arranged. Similar like layer 18, layer 26 also includes non-woven tape material, which has a noticeably higher capillarity than the material from which the absorbent Layers 12 and 14 are made of, for example, crepe tape-like material made of cellulose fibers. The length and width of the layer 26 are approximately the same as with layer 12, so that the inner and outer surfaces of layer 26 approximately the same area as the inner surface of layer 12, i. the surfaces of layer 26, those of layer 12 and part 22 of the coating opposite each other have approximately the same area and the same dimensions like the surface of the layer 12 opposite the part 22.

Wie vorstehend schon erwähnt, ist das Saugkissen 10 so ausgestaltet, daß es mit der absorbierenden Schicht 12 zum Körper des Anwenders hin zu benutzen ist. Der Innenteil 22 des Überzuges wird dabei in engen Kontakt mit dem Körper gebracht, so daß vom Körper ausgeschiedene Flüssigkeiten oder sonstige Ausscheidungen in Richtung des Pfeils 28 in Fig. 2 in das Kissen hineinfliessen können. Die Flüssigkeit durchdringt den Innenteil 22 des Überzuges ohne hierbei absorbiert zu werden, so daß der sich mit dem Körper in engem Kontakt befindliche Teil des Kissens relativ trocken bleibt, womit die größtmögliche Annehmlichkeit erzielt wird. Nachdem die Flüssigkeit den Teil 22 des Überzuges durchdrungen hat, gelangt sie in die der Flüssigkeitsverteilung dienende Schicht 26, die infolge ihrer relativ hohen Kapillarwirkung nicht nur die Flüssigkeit im wesentlichen gleichmäßig über die innere Oberfläche der absorbierenden Schicht 12 verteilt, sondern auch das Hindurchtreten der Flüssigkeit durch den Teil 22 des Überzuges beschleunigt.As already mentioned above, the suction pad 10 is designed so that it can be used with the absorbent layer 12 towards the body of the user is. The inner part 22 of the cover is brought into close contact with the body, so that the body excreted fluids or other excretions in the direction of the arrow 28 in Fig. 2 can flow into the pillow. The liquid penetrates the inner part 22 of the cover without being absorbed, so that the part of the pillow that is in close contact with the body remains relatively dry, with which the greatest possible convenience is achieved. After the liquid has passed the Has penetrated part 22 of the coating, it gets into the liquid distribution serving layer 26, which due to their relatively high capillary action not only the Liquid is substantially uniform over the inner surface of the absorbent Layer 12 distributed, but also the passage of the liquid through the part 22 of the coating accelerated.

Die in die Schicht 12 fliessende Flüssigkeit wird dort solange aufgehalten, bis diese Schicht vollkommen getränkt ist. Daraufhin fließt sie, da die Schicht 26 im wesentlichen flüssigkeitsundurchlässig ist, über die Ränder der Schicht 26 hinweg in die zweite der Flüssigkeitsverteilung dienende Schicht 18, wie in Fig. 2 durch Pfeile 30 angedeutet ist. Die Schicht 16 verhindert auf diese Weise, daß Flüssigkeit direkt in die Schicht 18 hineinfliessen kann und verringert hiermit die Möglichkeit, daß Flüssigkeit einen Teil des Saugkissens 10 durchdringen kann, bevor alle Teile durchtränkt worden sind. Die der Flüssigkeitsverteilung dienende Schicht 18 verteilt, ähnlich wie die Schicht 26 nicht nur die Flüssigkeit im wesentlichen gleichmässig über die innere Oberfläche der absorbierenden Schicht 14, von der ein Teil der äusseren Oberfläche der Schicht 16 gegenüberliegt, sondern verhindert auch, daß Flüssigkeit, die über die Ränder der Schicht 16 fließt an den Teil 22 des Überzuges zurückgelangen kann, Auf diese Weise fließt die Flüssigkeit in die Schicht 14 hinein, bis auch diese gesättigt ist, Die obenstehend geschilderten Vorgänge innerhalb des Saugkissens 10 gewährleisten die größtmögliche Annehmlichkeit für den Anwender, indem sie den Kontakt zwischen Flüssigkeit und Körper verringern und vergrößern die Ausnutzung des Materials, aus dem das Saugkissen besteht, indem sie sicherstellen, daß sämtliche seiner Teile befeuchtet werden, bevor die Flüssigkeit in einen anderen noch nicht befeuchteten Teil eindringt. Ausserdem weist das Kissen aufgrund der vorstehend gesohilderten Vorgänge eine relativ hohe Fähigkeit zur Flüssigkeitsaufnahme auf.The liquid flowing into layer 12 is held there until until this layer is completely soaked. It then flows as the layer 26 is substantially impervious to liquids beyond the edges of the layer 26 into the second layer 18 serving for liquid distribution, as shown in FIG. 2 is indicated by arrows 30. The layer 16 prevents in this way that Liquid can flow directly into the layer 18 and is hereby reduced the possibility that liquid can penetrate part of the absorbent pad 10, before all parts have been soaked. The one used to distribute the liquid Layer 18, similar to layer 26, not only distributes the liquid substantially uniformly over the inner surface of the absorbent layer 14, one of which Part of the outer surface of the layer 16 is opposite, but also prevents that liquid which flows over the edges of the layer 16 to the part 22 of the coating can get back, in this way the liquid flows into the layer 14, until this is also saturated, The processes described above within the Absorbent pad 10 ensure the greatest possible convenience for the user, by decreasing and increasing the contact between the fluid and the body the exploitation of the material from which the absorbent pad is made by ensuring that all of its parts are moistened before the liquid enters another not yet moistened part penetrates. In addition, the pillow has due to the The processes described above have a relatively high ability to absorb fluids on.

Wenn nicht durchlässiges, im wesentlichen aber flüssigkeits undurchlässiges flexibles bandförmiges Material für die Schicht 16 und den Aussenteil 24 des tberzuges verwendet werden, ergibt sich ein zusätzlicher Nutzen. Es fördert nämlich die Luftzirkulation zwischen dem Teil 24 des Überuges und der Schicht 16, die eine demgegenüber geringere Flächenausdehnung aufweist, die Verdunstung der im Kissen 10 aufgenommen Flüssigkeit und verlängert so die Dauer, während der das Kissen benutzt werden kann.If not permeable, but essentially liquid impermeable flexible band-shaped material for the layer 16 and the outer part 24 of the cover are used, there is an additional benefit. Namely, it promotes air circulation between the part 24 of the overhang and the layer 16, which in comparison has a smaller surface area has, the evaporation of the liquid contained in the cushion 10 and prolonged so the length of time the pillow can be used.

Das Kissen 10 wird nach einmaligem Gebrauch am besten weggeworfen. Da seine einzelnen Schichten vorzugsweise aus in Wasser auflösbarem Material bestehen, ist als hygienische und rationelle Beseitigungsethode das Wegspülen in der Toilette geeignet, da sie sich nach wenigen Augenblicken des Einweichens auflösen.The pillow 10 is best thrown away after a single use. Since its individual layers are preferably made of material that can be dissolved in water, is the hygienic and rational disposal method to flush it away in the toilet suitable as they dissolve after a few moments of soaking.

Man erkennt, daß das Saugkissen 10 in idealer Weise als Wegwerfwindel, als Monatsbinde oder als Wundverband geeignet ist, wenn Größe und Gestalt dem gewünschten Verwendungszweck angepaßt sind.It can be seen that the absorbent pad 10 is ideal as a disposable diaper, is suitable as a sanitary napkin or as a wound dressing, if the size and shape are the desired Purpose are adapted.

Vorstehend wurde ein bevorzugtes Ausführungsbeispiel im einzelnen beschrieben. Für den Fachmann sind dadurch noch verschiedene Modifikationen nahegelegt.A preferred embodiment has been described in detail above described. This also suggests various modifications for the person skilled in the art.
