Description
Mehrlagiger Verbandstoff Die Erfindung betrifft einen mehrlagigen Verbandstoff mit einer als Wundauflage ausgebildeten, durchlässigen, aus feuchtigkeitsbeständigem, an der Oberfläche faserfreiem Vliesstoff bestehenden Wundabieckung, die mit hinterlegten Saugschichten verbunden ist. Multi-layer dressing material The invention relates to a multi-layer dressing Bandage material with a permeable, moisture-resistant, on the surface of fiber-free non-woven fabric, which is deposited with the wound Absorbent layers is connected.
Mehrlagige Verbandstoffe für die Wundbehandlung bestehen aus einer Wundauflage, die mit Sauglagen kombiniert ist.Multi-layer bandages for wound treatment consist of one Wound pad combined with absorbent layers.
Die Wundauflage besteht aus wundverträglichen Geweben.The wound pad consists of wound-compatible tissues.
Sie kann auch aus perforierter Folie aus Kunststoffen oder Metallen bestehen. Die Sauglagen, die wundabseitig angeordnet sind, sind bei bekannten Ausfahrungsformen mit der Wundabdeckung bereits vernäht worden, wobei die Fäden jedoch stören. Es ist auch bekannt, eine Folie mit lochartigen Durchbrechungen zu versehen, wobei die Ränder der Durchlochungen in die Sauglagen hineinragen. Die Sauglagen können dann, ebenso wie bei sonstigen Wundabdeckungen, unmittelbar mit der Wunde in Berührung kommen.It can also be made of perforated plastic or metal foil exist. The suction layers, which are arranged away from the wound, are in known embodiments has already been sutured to the wound cover, but the threads interfere. It is also known to provide a film with hole-like openings, wherein the edges of the perforations protrude into the suction layers. The suction pads can then, as with other wound coverings, directly in contact with the wound come.
Weiterhin ist es bekannt, als Wundabdeckung ein faseriges Material durch Bindemittel zu verfestigen. Das Ausgangsmaterial wird mit einer stark wasserhaltigen Polyäthylen-Dispersion imprägniert, anschließend mehrfach getrocknet und dann zwischen heiBen Walzen gepreßt, sodaß das Material eine glatte, faserfreie Oberfläche erhält, die Jedoch in gleichmäßiger Verteilung von begrenzten Flächen des Polyäthylen-Filmes durchsetzt ist. Die Porosität eines derartigen Wundabdeckungsmaterials ist demnach einerseits durch die Anlagerung der Bindemittel und andererseits durch die Polyäthylen-Filmflächen bestimmt.It is also known to use a fibrous material as a wound covering to solidify by binding agents. The starting material is made with a highly hydrous Impregnated polyethylene dispersion, then dried several times and then between hot rollers pressed so that the material has a smooth, fiber-free surface, However, in an even distribution of limited areas of the polyethylene film is interspersed. The porosity of such a wound covering material is accordingly on the one hand through the accumulation of the binding agent and on the other hand through the polyethylene film surfaces certainly.
Es liegt also keine Mikroporosität vor, wie dieses gerade gemäß der vorliegenden Erfindung gefordert wird. Insbesondere soll die Wundabdeckung wie ein Diaphragma wirken, indem Wundausscheidungen mit Sicherheit von der Wunde zu den Saugschichten transportiert werden, Jedoch auch bei feuchter Sättigung der Saugschichten der Drockungsprozeß der Wunde nicht gestört wird. Darüberhinaus soll erreicht werden, den Sekrettransport von der Wunde her an keiner Stelle zu unterbrechen, d.h. dem sich austretenden Sekret setzen sich über die ganze gleichmäßig poröse Fläche keinerlei örtliche Verfestigungs- und damit Sperrpunkte entgegen.So there is no microporosity, as is the case according to FIG present invention is required. In particular, the wound covering should be like a The diaphragm work by securely moving exudates from the wound to the diaphragm Absorbent layers are transported, but also when the absorbent layers are saturated with moisture the drying process of the wound is not disturbed. In addition, it should be achieved not to interrupt the transport of secretions from the wound at any point, i.e. the emerging secretions do not settle over the entire evenly porous surface local consolidation and thus blocking points against.
Eine weitere Aufgabe besteht darin, daß die Saugschichten möglichst dicht an die Wundoberfläche herangeführt werden, ohne mit dieser in Kontakt zu kommen.Another object is that the absorbent layers as possible be brought close to the wound surface without coming into contact with it.
Dieses wird erfindungsgemäß dadurch erreicht, daß die Wundabdeckung aus einem bindemittelfrei-verfestigten, metallisierten Vliesstoff besteht, der mit seiner Rückseite auf einer der Außenseiten der in an sich bekannter Weise aus einzelnen übereinander angeordneten, untereinander verbundenen Lagen gebildeten Saugdicht durch in geringster Ausdehnung ausgeführter Verklebung bzw. Verschweißung mittels pulverförmig eingebrachter, unregelmäßig verteilter Bindemittel so fixiert ist, daß die völlig glatte Oberfläche der Wundabdeckung erhalten bleibt.This is achieved according to the invention in that the wound covering consists of a binder-free, bonded, metallized non-woven fabric that is joined with its back on one of the outer sides of the individual in a manner known per se superimposed, interconnected layers formed suction seal by gluing or welding carried out in the slightest extent by means of irregularly distributed binding agent that is introduced in powder form is fixed in such a way that that the completely smooth surface of the wound covering is retained.
Die Verbindungspunkte tragen wundseitig nicht auf, sodaß eine glatte Anschmiegung erreicht wird. Die Oberfläche der Wundabdeckung ist also völlig faserfrei und glatt.The connection points do not appear on the wound side, so that a smooth Snuggling is achieved. The surface of the wound covering is therefore completely free of fibers and smooth.
Die Sauglagen sind durch örtliche Prägung miteinander verbunden oder auch durch Verschweißung der einzelnen Lagen. Im letzteren Falle kann die Verschweißung bzw.The suction layers are or are connected to one another by local embossing also by welding the individual layers. In the latter case, the welding respectively.
Verklebung durch pulverförmig eingebrachte thermoplastische Kunststoffe erfolgen, wobei die Verbindung punktförmig, d. h. in geringster Flächenausdehnung ausgeführt ist.Bonding through powdered thermoplastic plastics take place, the connection point-like, d. H. in the smallest area is executed.
Die uiidabdeckuilg besteht bei einer bevorzugten Ausführungsform aus einem Vliesstoff, der ohne Spinnen oder Weben aus wundneutralen Fasern, insbesondere Zellulosefasern, bindemittelfrei durch Laugenbehandlung hergestellt ist.In a preferred embodiment, the uiidabdeckuilg consists of a non-woven fabric that is made from non-wound fibers, in particular without spinning or weaving Cellulose fibers, made without binding agents by means of a lye treatment.
Der Vliesstoff ist anschließend metallisiert oder hydrophobiert. Die Wundabdeckung ist durchlässig für Wundsekret, das unmittelbar durch die Sauglagen aufgenommen werden kann.The nonwoven is then metallized or hydrophobized. the Wound cover is permeable to wound secretion, which is directly passed through the absorbent layers can be included.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung wiedergegeben, das anhand der nachfolgenden Beschreibung näher erläutert wird. Es zeigen: Fig. 1 eine Schnittdarstellung, Fig. 2 eine Ansicht von oben.In the drawing, an embodiment of the invention is shown, which is explained in more detail with reference to the following description. They show: Fig. 1 is a sectional view, FIG. 2 is a view from above.
Die Wundabdeckung ist mit 10 bezeichnet, die Sauglagen mit 11, die Verbindungspunkte mit 12.The wound covering is denoted by 10, the absorbent layers by 11, the Connection points with 12.
Die Herstellung erfolgt z. B. in folgender Weise: Das metallisierte Vlies der Lage 10 wird auf Sauglagen 11 aufgebracht, die in erwünschter Schichtfolge und -stärke aus Zellstoff durch Prägung an den Punkten 12 vereinigt sind. Auf die vereinigten Sauglagen werden thermoplastische Kunststoffe, z. B. ein Pulver aus Polyäthylen, in schwacher Schicht aufgestäubt, worauf die Wundabdeckung auf die Sauglagen warm aufgepreßt wird. Statt eines Eunststoffklebers können auch alkohollösliche Kleber Verwendung finden, die beispielsweise dann aufgesprüht werden.The production takes place z. B. in the following way: The metallized Fleece of the layer 10 is applied to absorbent layers 11 in the desired layer sequence and strength from cellulose united by embossing at the points 12 are. Thermoplastics, z. B. a Polyethylene powder, dusted on in a weak layer, whereupon the wound cover is pressed warm on the absorbent layers. Instead of a plastic adhesive you can also use Find alcohol-soluble adhesives that are then sprayed on, for example.
Außer der Vereinigung der Sauglagen durch Prägung können diese ebenfalls durch eingestäubtes Kunstharzpulver örtlich vereinigt sein. Auch ist es möglich, örtliche Verschweißungspunkte so zu wahlen, daß punktförmige Verschweißungsmuster zwischen den Sauglagen und/oder der Wundabdeckung entstehen.In addition to the union of the suction layers by embossing, these can also be locally united by dusted synthetic resin powder. It is also possible to choose local welding points so that point-like welding patterns arise between the absorbent layers and / or the wound covering.
Die Wundabdeckung ist wundseitig völlig glatt und kann mit heilenden Zusätzen oder mit sonstigen Behandlungsmitteln versehen sein. Die Sauglagen bestehen aus Zellstoff oder entsprechend stark saugfähigem Material.The wound covering is completely smooth on the wound side and can be treated with healing Be provided with additives or other treatment agents. The suction layers exist made of cellulose or a correspondingly highly absorbent material.
Durch die erfindungsgemäße Verbindung der Sauglagen mit der Wundabdeckung wird eine völlig gleichförmige Oberfläche der Wundabdeckung erreicht, die weder Fäden, Durchstechungen noch sonstige indifferente Stellen aufweist.The inventive connection of the absorbent layers to the wound cover a completely uniform surface of the wound covering is achieved, which neither Has threads, punctures or other indifferent places.
Es ist somit an allen Stellen der Oberfläche eine gleichförmige Wirkung gesichert.There is thus a uniform effect at all points on the surface secured.
Die Sauglagen sind mit der Wundabdeckung fest verbunden, so daß die Schmiegsamkeit der Wundabdeckung nicht leidet und daß deren Handhabung eine unbesorgte Wundbehandlung erlaubt. Die Stärke der Sauglagen kann je nach den Erfordernissen der Wundbehandlung bemessen sein.The absorbent layers are firmly connected to the wound covering so that the The pliability of the wound covering does not suffer and that its handling is carefree Wound treatment allowed. The strength of the suction layers can be depending on the requirements be appropriate to wound treatment.
Sntsprechend erfolgt auch die Vereinigung der Lagen miteinander.The locations are also united with one another accordingly.
