Description
Mehrlagiger Verbandstoff
Die Erfindung betrifft einen mehrlagigen Verbandstoff mit einer durchlässigen Wundabdeckung, die mit Saugschichten hinterlegt ist. Die Wundauflage besteht bei bekannten, derartigen Verbandstoffen aus wundverträglichen Geweben. Sie kann auch aus perforierter Folie aus Kunststoffen oder Metallen bestehen. Die Sauglagen, die wundabseitig angeordnet sind, sind bei bekannten Ausführungsformen mit der Wundabdeckung bereits vernäht worden, wobei die Fäden jedoch stören. Es ist auch bereits 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.
Demgegenüber ist bei dem eingangs genannten mehrlagigen Verbandstoff erfindungsgemäss die aus feuchtigkeitsbeständigem Faservlies bestehende Wundabdeckung mit ihrer Rückseite auf den Saugschichten durch punktförmige Verbindungen fixiert. Nachstehend werden Ausführungsbeispiele der Erfindung erörtert.
Die Vereinigung der Wundabdeckung mit den Sauglagen kann durch punktförmige Verschweissung erfolgen. Die Sauglagen sind unter sich durch Prägung oder durch Verschweissung vereinigt. Die Verbindungspunkte tragen wundseitig nicht auf, so dass eine glatte Oberfläche und eine völlige Anschmiegung erreicht wird; die wundseitige Oberfläche der Wundabdeckung ist völlig homogen.
Die Sauglagen sind durch örtliche Prägung miteinander verbunden oder auch durch Verschweissung der einzelnen Lagen. Im letzteren Falle k-ann die Verschweissung bzw. Verklebung durch pulverförmig eingebrachte thermoplastische Kunststoffe erfolgen, wobei die Verbindung punktförmig ausgeführt ist.
In allen Fällen ist die Anordnung so getroffen, dass ganz überwiegend saugfähige Stellen verbleiben.
Auch ist die Vereinigung mit der Wundabdeckung bzw. der Sauglagen untereinander durch thermoplastische Fasern oder Fäden möglich, die auch Bestandteile der Lagen sein können.
Die Wundabdeckung besteht bei einer bevorzugten Ausführungsform aus einem Faservlies, das ohne Spinnen oder Weben aus wundneutralen Fasern hergestellt ist. Das Faservlies kann z. B. auch in metallisierter oder hydrophobierter Form Anwendung finden. Die Wundabdeckung ist durchlässig für Wundsekret, das unmittelbar durch die Sauglagen aufgenommen werden kann.
Auf der Zeichnung ist ein Ausführungsbeispiel der Erfindung schematisch dargestellt, und zwar zeigt:
Fig. 1 eine Schnittdarstellung,
Fig. 2 eine Ansicht von oben.
Die durchlässige Wundabdeckung ist mit 10 bezeichnet, die Sauglagen mit 11, die Verbindungspunkte mit 12.
Die Herstellung erfolgt z. B. in folgender Weise: Das z. B. metallisierte Vlies der Lage 10 wird auf Sauglagen 11 aufgebracht, die in erwünschter Schichtfolge und -dicke 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, so dass punktförmige Verbindungen entstehen. Statt eines Kunststoffklebers können auch alkohollösliche Kleber Verwendung finden, die beispielsweise dann aufgesprüht werden.
Ausser der Vereinigung der Sauglagen durch Prägung können diese ebenfalls durch eingestäubtes Kunstharzpulver örtlich vereinigt sein. Auch ist es möglich, örtliche Verschweissungspunkte so zu wählen, dass punktförmige Verschweissungsmuster zwi schen den Sauglagen und/oder der Wundabdeckung entstehen.
Die aus einem feuchtigkeitsbeständigen Faservlies bestehende Wundabdeckung ist wundseitig völlig glatt. Die Sauglagen bestehen aus Zellstoff oder entsprechend stark saugfähigem Material.
Durch die punktförmige Verbindung der Sauglagen mit der Wundabdeckung wird eine völlig gleichförmige Oberfläche der Wundabdeckung erreicht, die weder Fäden, Durchstechungen noch sonstige indifferente Stellen aufweist. Es ist somit an allen Stellen der Oberfläche eine gleichförmige Wirkung gesichert.
Die Sauglagen sind mit der Wundabdeckung punktförmig fest verbunden, jedoch so, dass die Schmiegsamkeit der Wundabdeckung nicht leidet, und dass deren Handhabung eine unbesorgte Wundbehandlung erlaubt. Die Stärke der Sauglagen kann je nach der erforderlichen Wundbehandlung eingerichtet sein. Entsprechend erfolgt auch die Vereinigung der Lagen miteinander.
Multi-layer dressing material
The invention relates to a multi-layer bandage material with a permeable wound covering which is backed with absorbent layers. In known dressing materials of this type, the wound pad consists of wound-compatible tissues. It can also consist of a perforated film made of plastics or metals. The absorbent layers, which are arranged away from the wound, have already been sutured to the wound covering in known embodiments, but the threads interfere. It is also already known to provide a film with hole-like perforations, the edges of the perforations protruding into the absorbent layers. As with other wound coverings, the absorbent layers can then come into direct contact with the wound.
In contrast, in the case of the multi-layer bandage material mentioned at the beginning, the wound covering consisting of moisture-resistant fiber fleece is fixed with its rear side on the absorbent layers by point-like connections. Embodiments of the invention are discussed below.
The union of the wound covering with the absorbent layers can be done by point-like welding. The suction layers are united by embossing or welding. The connection points do not appear on the wound side, so that a smooth surface and a perfect fit is achieved; the wound-side surface of the wound covering is completely homogeneous.
The suction layers are connected to one another by local embossing or by welding the individual layers. In the latter case, the welding or gluing can be carried out by means of thermoplastic plastics introduced in powder form, the connection being made point-like.
In all cases, the arrangement is made so that predominantly absorbent areas remain.
It is also possible to combine the wound covering or the absorbent layers with one another by means of thermoplastic fibers or threads, which can also be components of the layers.
In a preferred embodiment, the wound covering consists of a fiber fleece which is produced from non-wound fibers without spinning or weaving. The nonwoven fabric can, for. B. can also be used in metallized or hydrophobized form. The wound cover is permeable to wound secretion, which can be absorbed directly through the absorbent layers.
In the drawing, an embodiment of the invention is shown schematically, namely shows:
1 is a sectional view,
Fig. 2 is a view from above.
The permeable wound covering is denoted by 10, the absorbent layers by 11, and the connection points by 12.
The production takes place z. B. in the following way: The z. B. metallized fleece of the layer 10 is applied to absorbent layers 11, which are combined in the desired layer sequence and thickness of cellulose by embossing at the points 12. On the combined suction layers, thermoplastics such. B. a powder made of polyethylene, dusted in a weak layer, whereupon the wound cover is pressed warm on the absorbent layers, so that point-like connections are formed. Instead of a plastic adhesive, alcohol-soluble adhesives can also be used, which are then sprayed on, for example.
Apart from 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 cover.
The wound covering, made of a moisture-resistant fiber fleece, is completely smooth on the wound side. The absorbent layers are made of cellulose or a correspondingly highly absorbent material.
The punctiform connection of the absorbent layers to the wound cover results in a completely uniform surface of the wound cover that has neither threads, punctures nor other indifferent places. A uniform effect is thus ensured at all points on the surface.
The absorbent layers are firmly connected to the wound covering in punctiform fashion, but in such a way that the pliability of the wound covering does not suffer, and that its handling allows a carefree wound treatment. The strength of the absorbent layers can be adjusted depending on the wound treatment required. The layers are also united with one another accordingly.
