- the anti-microbial wound protection composite material is tubular so that it can be quickly and precisely placed over a wound located on the human extremities, such as the upper arm or calf. Due to the tubular geometry, which is formed in the simplest case as a uniform hollow cylinder, eliminates complicated winding and connecting the wound with conventional dressing materials.
- the tubular, antimicrobial composite material for wound protection in addition to the preferably cylindrical hollow shape, also has a conical design.
- conical is meant that a first opening of the tubular antimicrobial composite material has a smaller cross-section than a second opening, so that the cross-section widens conically in the longitudinal direction of the tubular composite material from the first opening to the second opening.

- the material layer can preferably be stitched with the first layer material, most preferably double-stitched. This is advantageous because the resulting stitching seam is particularly stable, tear-resistant and stress-resistant due to the lockstitch, in particular the lockstitch, and consequently withstands a continuous load of frequent application and removal of the tubular composite material.
- This effect is reinforced by the formation of a double stitched seam for fixing the first layer material to the material layer.
- this training of sewing is also providable so that by Versteppung, preferably by double stitch quilting, a permanent, solid, stitched fixation of the first and second
- Layer material and the at least partially arranged therebetween material layer is formed.

If the material layer is designed as a suction element, then this is advantageous for absorbing water vapor, which is caused, for example, by welding, to remove this water vapor from the first layer material and buffer it. This is particularly advantageous, since thus the first layer material arranged facing the patient essentially always remains dry, so that a foreign nucleation, which causes inflammation or fever, is avoided. Furthermore, the material layer formed as a suction element discharges water vapor, for example by sweating through the tubular, antimicrobial composite material, to the environment. This is particularly advantageous because thus no waterlogging is conditional and foreign germs can not multiply to cause inflammation and fever.
- the composite material is growth-inhibiting with respect to germs, bacteria, viruses, mites and / or fungi and / or a combination thereof.
- This growth-inhibiting formation of the composite material takes place by the use of inorganic ions, preferably metal cations, more preferably silver ions, so that the cells of, for example, germs, bacteria or viruses are damaged and destroyed.

- this is formed odor-inhibiting. This is advantageous because thus sweat odor, which is often formed by movements, is prevented. The patient is thus not affected by a foul smelling sweat or odor. Odor inhibition takes place by the arrangement of elemental silver and / or silver ions, preferably silver cations, in the fabric material mixture and / or the carrier material of the first and / or second layer material. In a further advantageous embodiment, this is designed to be washable and / or dimensionally stable. This is advantageous since the tubular, antimicrobial composite material can thus be applied in multiple ways and can preferably be disinfected and sterilized. The composite material is preferably washable at least 60 degrees, most preferably at least 95 degrees. Furthermore, it is advantageous that the composite material is dimensionally stable and is designed distortion-free with long wear or multiple use and does not widen or narrow.

Description
Schlauchförmiges, antimikrobielles Verbundmaterial Tubular, antimicrobial composite material
Beschreibung description
Die vorliegende Erfindung betrifft ein schlauchförmiges, antimikrobielles Verbundmaterial zum Wundschutz. Aus dem Stand der Technik sind derartige Verbände zum Wundschutz bekannt, welche allerdings häufig lediglich zur Wundabdeckung verwendet werden. Zur Versorgung und Desinfektion der zu versorgenden Wunde bedarf es zusätzlicher Medikamente, welche auch regelmäßig aufgebracht werden müssen, um die Wunde optimal zu versorgen und vor Fremdkeimen und Entzündungen frei zu halten. Daher bedarf es meist mehrmals am Tag eines entsprechenden Verbandwechsels. Zudem nimmt herkömmliches Verbandsmaterial häufig Schmutz und Verunreinigungen auf und führt diese durch die grobmaschige Textilstruktur zur Wunde hin, um dort Entzündungen hervorzurufen. The present invention relates to a tubular, antimicrobial composite material for wound protection. Such dressings for wound protection are known in the prior art, which, however, are often used only for wound covering. To supply and disinfect the wound to be treated requires additional medication, which must also be applied regularly to optimally care for the wound and to keep it free of foreign germs and inflammation. Therefore, it usually takes several times a day a corresponding dressing change. In addition, conventional bandage material often picks up dirt and contaminants and guides them through the coarse-meshed textile structure to the wound to cause inflammation there.
Daher ist es Aufgabe der vorliegenden Erfindung, ein schlauchförmiges, antimikrobielles Verbundmaterial zum Wundschutz bereitzustellen, welches die Wundheilung beschleunigt und welches das Wachstum von Keimen, wie beispielsweise Bakterien oder Pilzen, verhindert. Therefore, it is an object of the present invention to provide a tubular, anti-microbial composite material for wound protection which accelerates wound healing and which prevents the growth of germs such as bacteria or fungi.
Diese Aufgabe wird gemäß des Patentanspruches 1 sowie des nebengeordneten Patentan- Spruches 9 gelöst. Weitere vorteilhafte Ausführungsformen werden in den Unteransprüchen offenbart. This object is achieved according to the patent claim 1 and the independent patent claim 9. Further advantageous embodiments are disclosed in the subclaims.
BESTÄTIGUNGSKOPIE
Die Kernidee des erfindungsgemäßen schlauchförmigen, antimikrobiellen Verbundmaterials zum Wundschutz besteht darin, dass dieses ein erstes einem Patienten zugewandt angeordnetes Schichtmaterial, umfassend wenigstens ein Trägermaterial zur Stabilisierung des Schichtmaterials sowie wenigstens ein Gewebematerialgemisch, welches wenigstens einen Naturfaseranteil im Bereich von 10 - 15 Volumenprozent umfasst, ein dem Patienten abgewandt angeordnetes zweites Schichtmaterial, umfassend wenigstens ein Trägermaterial zur Stabilisierung des Schichtmaterials sowie wenigstens ein Gewebematerialgemisch, welches wenigstens einen Naturfaseranteil im Bereich von 10 - 50 Volumenprozent umfasst und wenigstens eine zumindest teilweise zwischen den beiden Schichtmaterialien angeordnete Ma- teriallage, insbesondere aus Kunststoff, wobei das Verbundmaterial atmungsaktiv ausgebildet ist, umfasst. CONFIRMATION COPY The core idea of the tubular, antimicrobial composite material according to the invention for wound protection is that it comprises a first patient-facing layer material comprising at least one support material for stabilizing the layer material and at least one tissue material mixture comprising at least one natural fiber fraction in the range 10-15% by volume facing away from the patient second layer material, comprising at least one carrier material for stabilizing the layer material and at least one tissue material mixture comprising at least one natural fiber content in the range of 10 to 50 percent by volume and at least one at least partially disposed between the two layer materials matriallage, in particular of plastic, wherein the composite material is breathable.
Dies ist insbesondere vorteilhaft, wenn das schlauchförmige, antimikrobielle Verbundmaterial über einer Wunde, beispielsweise an den menschlichen Extremitäten, wie Armen oder Bei- nen, angeordnet wird, ohne dass weitergehende Cremeschichten oder Wundkompressen über der Wunde angeordnet werden müssen. Insbesondere dicke Cremeschichten, welche von Wundkompressen bilden ein nahezu geschlossenes und isoliertes System um die Wunde herum aus, sodass eine Atmungsaktivität im Sinne von Wasserdampfaustausch zwischen Wundenoberfläche und Umgebung nicht möglich ist. Durch diese im Wesentlichen als Isola- tionsschichten zu verstehenden Creme-Kompressenschichten besteht eine deutlich erhöhte Gefahr von Keimbildung, welche zu Entzündungen, Eiterbildung oder Fieber des Patienten führen können. This is particularly advantageous when the tubular antimicrobial composite material is placed over a wound on, for example, the human extremities, such as arms or legs, without having to place more cream layers or wound compresses over the wound. In particular, thick cream layers which form wound compresses form a virtually closed and isolated system around the wound, so that a breathability in the sense of water vapor exchange between the wound surface and the environment is not possible. As a result of these cream compress layers, which are essentially to be understood as insulation layers, there is a significantly increased risk of nucleation, which can lead to inflammation, pus formation or fever of the patient.
Das erfindungsgemäße schlauchförmige, antimikrobielle Verbundmaterial ist aufgrund der verwendeten Materialzusammensetzungen in den zwei Schichtmaterialien und bevorzugt auch in der dazwischen angeordneten Materiallage atmungsaktiv ausgebildet. Unter atmungsaktiv ist vorliegend die Fähigkeit zu verstehen, Wasserdampf von der Hautoberfläche/Wundenoberfläche des Patienten abzuführen. Bevorzugt ist die Atmungsaktivität zumindest derart ausgebildet, dass sich bildender Wasserdampf, beispielsweise durch Schwitzen, von der Hautoberfläche/Wundoberfläche durch das schlauchförmige, antimikrobielle Verbundmaterial hindurch an die Umgebung abgebbar ist. The tubular, antimicrobial composite material according to the invention is made breathable due to the material compositions used in the two layer materials and preferably also in the material layer arranged therebetween. Breathable herein means the ability to remove water vapor from the skin surface / wound surface of the patient. Preferably, the breathability is at least such that water vapor forming, for example by sweating, can be released from the skin surface / wound surface through the tubular, antimicrobial composite material to the environment.
Ferner ist auch denkbar, dass durch das schlauchförmige, antimikrobielle Verbundmaterial
auch in entgegengesetzter Flussrichtung Wasserdampf zu der Hautoberfläche des Patienten hin zuführbar ist. Furthermore, it is also conceivable that the tubular, antimicrobial composite material Also in the opposite direction of flow of water vapor can be supplied to the skin surface of the patient.

As the synthetic fiber, a polyester is preferably used. The carrier material and the tissue material mixture are firmly fixed to each other according to the invention.
Der Naturfaseranteil des Trägermaterials ist bevorzugt aus der Gruppe Samenfasern, wie meist bevorzugt Baumwolle, Bastfasern, Blattfasern, wie beispielsweise Sisal, oder Fruchtfasern, wie beispielsweise Kokos, ausgewählt. The natural fiber content of the carrier material is preferably selected from the group of seed fibers, such as most preferably cotton, bast fibers, leaf fibers, such as sisal, or fruit fibers, such as coconut.
Unter Naturfasern sind vorliegend alle Fasern zu verstehen, welche von Pflanzen, Tieren stammen und welche ohne chemische Veränderung verwendet werden. Unter Kunstfasern sind vorliegend künstliche und/oder natürliche Polymere zu verstehen.

In the present case, the synthetic fiber is preferably selected from the group consisting of polyester, polyethylene terephthalate, polyamide, polyimide, polyamide-imide, polyacrylonitrile, polytetrafluoroethylene, polyethylene, polypropylene, polyvinyl chloride, polyurethane, polyethersulfone fiber and / or a combination thereof. tion selected from this.
Das Trägermaterial weist bevorzugt eine Stärke von 0,5 bis 2 mm auf. Das erste Schichtmaterial umfassend Trägermaterial und Gewebematerialgemisch weist bevorzugt eine flächenbezogene Masse im Bereich von 80 bis 300 g/m2, mehr bevorzugt von 120 bis 170 g/m2, auf. The support material preferably has a thickness of 0.5 to 2 mm. The first layer material comprising carrier material and fabric material mixture preferably has a basis weight in the range from 80 to 300 g / m 2 , more preferably from 120 to 170 g / m 2 .
Der Naturfaseranteil im Gewebematerialgemisch umfasst einen Bereich von 10 - 50 Volumenprozent, bevorzugt einen Bereich von 15 - 40 Volumenprozent. Die Naturfaser für das Gewebematerialgemisch wird bevorzugt aus der Gruppe Samenfasern, wie meist bevorzugt Baumwolle, Bastfasern, Blattfasern, wie beispielsweise Sisal, oder Fruchtfasern, wie bei-
spielsweise Kokos, ausgewählt, wobei meist bevorzugt Baumwolle als Naturfaser ausgewählt ist. Die Verarbeitung einer Naturfaser ist besonders vorteilhaft für die Atmungsaktivität des schlauchförmigen Verbundmaterials sowie für die Wasserdampfdurchlässigkeit. Folglich werden Hautirritation und -ekzeme vermieden. Ferner erweisen sich Naturfasern als beson- ders hautverträglich und allergenarm. The natural fiber content in the fabric material mixture comprises a range of 10-50% by volume, preferably a range of 15-40% by volume. The natural fiber for the fabric material mixture is preferably selected from the group of seed fibers, such as most preferably cotton, bast fibers, leaf fibers, such as sisal, or fruit fibers, such as For example, coconut, selected, with most preferably cotton is selected as natural fiber. The processing of a natural fiber is particularly advantageous for the breathability of the tubular composite material as well as for the water vapor permeability. Consequently, skin irritation and eczema are avoided. Furthermore, natural fibers prove to be particularly skin-friendly and low-allergen.
Neben dem Naturfaseranteil umfasst das Gewebematerialgemisch einen Kunstfaseranteil in einem Bereich von 50 - 90 Volumenprozent, bevorzugt einen Bereich von 60 - 85 Volumenprozent. Vorliegend wird die Kunstfaser bevorzugt aus der Gruppe Polyester-, Polyethylente- rephthalat-, Polyamid-, Polyimid-, Polyamidimid-, Polyacrylnitril-, Polytetrafluorethylen-, Polyethylen-, Polypropylen-, Polyvinylchlorid-, Polyurethan-, Polyethersulfonfaser und/oder eine Kombination hieraus ausgewählt. Meist bevorzugt ist ein Polyester vorgesehen, welches ein Molekulargewicht (Gewichtsmittel) von 40.000 bis 60.000 g/mol, bevorzugt 45.000 g/mol aufweist. Zudem ist bevorzugt, dass die verwendete Kunstfaser wenigstens ein Additiv und/oder wenigstens eine anorganische metallische Verbindung aufweist. Meist bevorzugt ist die Kunstfaser silberhaltig ausgebildet. Das verwendete Silber kann als elementares Silber vorliegen oder als Ion, insbesondere Kation. In addition to the natural fiber content, the fabric material mixture comprises a synthetic fiber content in a range of 50-90 volume percent, preferably a range of 60-85 volume percent. In the present case, the synthetic fiber is preferably selected from the group consisting of polyester, polyethylene terephthalate, polyamide, polyimide, polyamide-imide, polyacrylonitrile, polytetrafluoroethylene, polyethylene, polypropylene, polyvinyl chloride, polyurethane, polyethersulfone fiber and / or a combination thereof selected. Most preferably, a polyester is provided which has a molecular weight (weight average) of 40,000 to 60,000 g / mol, preferably 45,000 g / mol. In addition, it is preferred that the synthetic fiber used has at least one additive and / or at least one inorganic metallic compound. Most preferably, the synthetic fiber is formed silver. The silver used may be present as elemental silver or as an ion, in particular cation.
Es ist denkbar, dass das Silber bereits innerhalb des Volumens der Kunstfaser angeordnet ist oder auch lediglich an deren Oberfläche beispielsweise als Beschichtung aufgebracht ist. Elementare Silber und/oder Silberionen werden von Keimen, Bakterien, Viren, Milben, Pilzen o.ä. aufgenommen und bedingt deren Zellzerstörung. Somit wird eine Zellteilung und eine Ausbreitung bzw. Vervielfachung der Keime, Bakterien, Viren, Milben oder Pilze verhindert und das Schichtmaterial, in welchem die Kunstfaser verarbeitet ist, weist eine antimikrobielle Eigenschaft auf. It is conceivable that the silver is already arranged within the volume of the synthetic fiber or is merely applied to its surface, for example as a coating. Elemental silver and / or silver ions are or the like of germs, bacteria, viruses, mites, fungi. recorded and caused their cell destruction. Thus, cell division and propagation of germs, bacteria, viruses, mites or fungi is prevented and the sheet material in which the synthetic fiber is processed has an antimicrobial property.
Bevorzugt ist das Gewebematerialgemisch, als Stapelfasergarn, meist bevorzugt als Ringgarn, herstellbar und mit dem Trägermaterial fest verbindbar, so dass im Wesentlichen das Gewebematerialgemisch zu der zu überdeckenden Wunde direkt benachbart angeordnet ist. Sowohl Gewebematerialgemisch als auch Trägermaterial sind bevorzugt als Ringgarn herstellbar und verwendbar. Preferably, the fabric material mixture, as Stapelfasergarn, usually preferably as ring yarn, produced and firmly connected to the carrier material, so that substantially the tissue material mixture is arranged directly adjacent to the wound to be covered. Both fabric material mixture and carrier material are preferably produced and usable as a ring yarn.
Unter Ringgarn ist hierbei ein Garn zu verstehen, welches mittels speziellem Spinnverfahren herstellbar ist, so dass das hierdurch hergestellte Ringgarn besonders reißfest und stabil ist.
Bevorzugt umfassen die Ringgarne, aus welchen das Trägermaterial sowie das Gewebematerialgemisch hergestellt wird, wenigstens zwei Fasern. Under ring yarn here is a yarn to understand, which can be produced by means of a special spinning process, so that the ring yarn thus produced is particularly tear-resistant and stable. The ring yarns from which the carrier material and the fabric material mixture are produced preferably comprise at least two fibers.
Bevorzugt liegen die verwendeten Kunst- und/oder Naturfasern als Spinnfasern, Flockfasern, Stapelfasern, endlos Filamente und/oder einer Kombination hieraus vor. Preferably, the synthetic and / or natural fibers used are present as staple fibers, flock fibers, staple fibers, endless filaments and / or a combination thereof.
Das antimikrobielle Verbundmaterial zum Wundschutz ist schlauchförmig ausgebildet, sodass es schnell und präzise über einer Wunde angeordnet werden kann, welche sich an den menschlichen Extremitäten, wie beispielsweise Oberarm oder Wade, befindet. Durch die schlauchförmige Geometrie, welche im einfachsten Fall als gleichmäßiger Hohlzylinder ausgebildet ist, entfällt aufwendiges Wickeln und Verbinden der Wunde mit herkömmlichen Verbandsmaterialien. Je nach Ausführungsbeispiel weist das schlauchförmige, antimikrobielle Verbundmaterial zum Wundschutz neben der bevorzugt zylindrischen Hohlform, auch eine konische Ausbildung auf. Unter konisch ist hierbei zu verstehen, dass eine erste Öffnung des schlauchförmigen, antimikrobiellen Verbundmaterial einen geringeren Querschnitt aufweist als eine zweite Öffnung, so dass sich der Querschnitt in Längsrichtung des schlauchförmigen Verbundmaterials von der ersten Öffnung zur zweiten Öffnung hin konisch erweitert. Dies ist beispielsweise von Vorteil, wenn Wunden an der Wade geschützt werden sollen. Das dem Patienten abgewandt angeordnete zweite Schichtmaterial gemäß Anspruch 1 weist bevorzugt die gleiche Materialzusammensetzung auf, wie für das erste Schichtmaterial bereits beschrieben. Selbstverständlich ist die Materialzusammensetzung nicht hierauf begrenzt, sondern in den oben genannten Volumenbereichen bzw. -Verhältnissen variabel anpassbar. The anti-microbial wound protection composite material is tubular so that it can be quickly and precisely placed over a wound located on the human extremities, such as the upper arm or calf. Due to the tubular geometry, which is formed in the simplest case as a uniform hollow cylinder, eliminates complicated winding and connecting the wound with conventional dressing materials. Depending on the exemplary embodiment, the tubular, antimicrobial composite material for wound protection, in addition to the preferably cylindrical hollow shape, also has a conical design. By conical is meant that a first opening of the tubular antimicrobial composite material has a smaller cross-section than a second opening, so that the cross-section widens conically in the longitudinal direction of the tubular composite material from the first opening to the second opening. This is for example advantageous if wounds on the calf are to be protected. The patient facing away from the second layer material according to claim 1 preferably has the same material composition, as already described for the first layer material. Of course, the material composition is not limited thereto, but variably adaptable in the above-mentioned volume ranges or ratios.
Zwischen den beiden Schichtmaterialien ist erfindungsgemäß zumindest teilweise wenigstens eine Materiallage angeordnet, welche bevorzugt aus Kunststoff und meist bevorzugt als Nadelfilz-Vlies, ausgebildet ist. Die Materiallage weist bevorzugt eine Dicke im Bereich von 0,2 bis 50 mm, bevorzugt von 0,5 bis 15 mm, auf. According to the invention, at least in part at least one layer of material is arranged between the two layer materials, which layer is preferably made of plastic and most preferably as needle felt fleece. The material layer preferably has a thickness in the range from 0.2 to 50 mm, preferably from 0.5 to 15 mm.
Erfindungsgemäß ist die Materiallage mit dem ersten Schichtmaterial, welches dem Patienten zugewandt angeordnet ist, fest verbindbar, insbesondere ist die Materiallage mit dem ersten Schichtmaterial manuell und/oder maschinell vernähbar. Für diese Fixierung wird meist bevorzugt eine Vielnadelsteppmaschine eingesetzt, welche mehrere Nadelreihen mit
geringen Nadelabständen aufweist. Die Materiallage ist bevorzugt mit dem ersten Schichtmaterial versteppbar, meist bevorzugt doppelstichversteppbar, ausgebildet. Dies ist vorteilhaft, da durch den Steppstich, insbesondere dem Doppelsteppstich, die resultierende Steppnaht besonders stabil, reißfest und strapazierbar ausgebildet ist und folglich einer Dauerbe- lastung von häufigem An- und Ausziehen des schlauchförmigen Verbundmaterials standhält. Verstärkt ist dieser Effekt durch die Ausbildung einer Doppelstichsteppnaht zur Fixierung des ersten Schichtmaterials mit der Materiallage. Selbstverständlich ist diese Ausbildung des Vernähens auch derart vorsehbar, dass mittels Versteppung, bevorzugt mittels Doppelstich- versteppung, eine dauerhafte, feste, durchgenähte Fixierung des ersten und zweiten According to the invention, the material layer can be fixedly connected to the first layer material which is arranged facing the patient; in particular, the material layer can be manually and / or mechanically sewn to the first layer material. For this fixation is usually preferred a multi-needle stitching machine used, which several needle rows with having small needle spacings. The material layer can preferably be stitched with the first layer material, most preferably double-stitched. This is advantageous because the resulting stitching seam is particularly stable, tear-resistant and stress-resistant due to the lockstitch, in particular the lockstitch, and consequently withstands a continuous load of frequent application and removal of the tubular composite material. This effect is reinforced by the formation of a double stitched seam for fixing the first layer material to the material layer. Of course, this training of sewing is also providable so that by Versteppung, preferably by double stitch quilting, a permanent, solid, stitched fixation of the first and second
Schichtmaterials sowie der zumindest teilweise dazwischen angeordneten Materiallage ausgebildet ist. Dies ist vorteilhaft, da die resultierenden Steppnähte, insbesondere Doppelstichsteppnähte, eine Oberflächengestaltung des schlauchförmigen Verbundmaterials bedingen. Durch diese Versteppung, bevorzugt Doppelstichversteppung, von erstem Schichtmaterial mit Materiallage und mit zweitem Schichtmaterial sind Kammerelemente mit wenigstens ei- nem Wölbungsmaximum ausgebildet, wobei die Kammerelemente eine Polsterwirkung aufweisen. Somit sind vorteilhaft Druckstellen und Hautekzeme vermeidbar. Layer material and the at least partially arranged therebetween material layer is formed. This is advantageous because the resulting stitching, in particular double stitched stitching, necessitates a surface design of the tubular composite material. As a result of this desertification, preferably double stitch stitching, of first layer material with material layer and with second layer material, chamber elements with at least one arching maximum are formed, wherein the chamber elements have a cushioning effect. Thus, pressure points and dermal eczema are advantageously avoidable.
Bevorzugt umfassen erstes und zweites Trägermaterial und/oder erstes und zweites Gewebematerialgemisch die gleiche Faserzusammensetzung auf. Vorteilhaft weisen erstes und zweites Trägermaterial eine Materialdicke von 0,2 bis 10 mm, bevorzugt von 0,5 bis 3 mm auf. Vorteilhaft weisen erstes und zweites Gewebematerialgemisch eine Materialdicke von 0,2 bis 25 mm, bevorzugt von 0,5 bis 5 mm auf. Ferner ist denkbar, dass bei gleicher Faserzusammensetzung die beiden Trägermaterialien und/oder die beiden Gewebematerialgemische von einander verschiedene Materialdicken aufweisen. So kann das erste und zweite Trägermaterial eine im Wesentlichen gleiche Dicke aufweisen und zeitgleich die beiden Gewebematerialgemische ein voneinander verschiedene Materialdicke aufweisen und umgekehrt. Als Bezug für die Materialdicke der jeweiligen Schichten ist diese in ihrem jeweiligen unkomprimierten Ausgangszustand zu verstehen. In einer weiteren vorteilhaften Ausführungsform ist das schlauchförmige, antimikrobielle Verbundmaterial mehrlagig, bevorzugt aus 2 - 5 Materialschichten, ausgebildet. Vorteilhaft ist diese mehrlagige Ausbildung des Verbundmaterials sandwichartig vorgesehen, sodass jeweils zwei Schichtmaterialien von einer dazwischen angeordneten Materiallage zumindest teilweise voneinander beabstandet angeordnet sind. Dies ist vorteilhaft sofern ein Polsteref-
fekt gewünscht ist. Bevorzugt weist der schlauchförmige, antimikrobielle Verbundmaterial eine Schichtenfolge von A-B-C-B-A auf, wobei A das jeweilige Gewebematerialgemisch, B das jeweilige Trägermaterial und C die Materiallage darstellt. Bei einer weiteren vorteilhaften Ausführungsform ist die Materiallage als Dämpfungselement und/oder als Saugelement ausgebildet. Dies ist vorteilhaft, da die Materiallage als Dämpfungselement eine Polsterwirkung aufweist und zugleich auch die Körperwärme hält. Ferner wird der Tragekomfort bei dem Patienten erhöht. Ist die Materiallage als Saugelement ausgebildet, so ist dies vorteilhaft zur Aufnahme von Wasserdampf, welcher beispielsweise durch Schweiß bedingt wird, diesen Wasserdampf von dem ersten Schichtmaterial abzuführen und zwischenzuspeichern. Dies ist insbesondere vorteilhaft, da somit das dem Patienten zugewandt angeordnete erste Schichtmaterial im Wesentlichen immer trocken bleibt, sodass eine Fremdkeimbildung, welche Entzündungen oder Fieber bedingen, vermieden wird. Ferner führt die als Saugelement ausgebildete Materiallage entstehenden Wasserdampf, bei- spielsweise durch Schwitzen durch das schlauchförmige, antimikrobielle Verbundmaterial an die Umgebung ab. Dies ist insbesondere von Vorteil, da somit keine Staunässe bedingt wird und sich Fremdkeime nicht vermehren können, um Entzündungen und Fieber zu bedingen. Preferably, first and second carrier material and / or first and second tissue material mixtures comprise the same fiber composition. Advantageously, the first and second carrier material have a material thickness of 0.2 to 10 mm, preferably 0.5 to 3 mm. Advantageously, the first and second fabric material mixtures have a material thickness of 0.2 to 25 mm, preferably 0.5 to 5 mm. Furthermore, it is conceivable that, given the same fiber composition, the two carrier materials and / or the two fabric material mixtures have different material thicknesses from each other. Thus, the first and second carrier material may have a substantially equal thickness and at the same time the two fabric material mixtures have a different material thickness from each other and vice versa. As a reference for the material thickness of the respective layers, this is to be understood in their respective uncompressed initial state. In a further advantageous embodiment, the tubular, antimicrobial composite material is multi-layered, preferably from 2 to 5 material layers. Advantageously, this multilayer construction of the composite material is sandwiched, so that in each case two layer materials are arranged at least partially spaced from one another by a material layer arranged therebetween. This is advantageous if a cushioning is desired. The tubular, antimicrobial composite material preferably has a layer sequence of ABCBA, where A represents the respective fabric material mixture, B the respective carrier material and C the material layer. In a further advantageous embodiment, the material layer is designed as a damping element and / or as a suction element. This is advantageous because the material layer has a cushioning effect as a damping element and at the same time also holds the body heat. Furthermore, the wearing comfort in the patient is increased. If the material layer is designed as a suction element, then this is advantageous for absorbing water vapor, which is caused, for example, by welding, to remove this water vapor from the first layer material and buffer it. This is particularly advantageous, since thus the first layer material arranged facing the patient essentially always remains dry, so that a foreign nucleation, which causes inflammation or fever, is avoided. Furthermore, the material layer formed as a suction element discharges water vapor, for example by sweating through the tubular, antimicrobial composite material, to the environment. This is particularly advantageous because thus no waterlogging is conditional and foreign germs can not multiply to cause inflammation and fever.
Bei einer weiteren vorteilhaften Ausführungsform ist das Verbundmaterial wachstumshem- mend bezüglich Keimen, Bakterien, Viren, Milben und/oder Pilzen und/oder einer Kombination hieraus ausgebildet. Diese wachstumshemmende Ausbildung des Verbundmaterials erfolgt durch die Verwendung von anorganischen Ionen, bevorzugt Metallkationen, mehr bevorzugt Silberionen, so dass die Zellen von beispielsweise Keimen, Bakterien oder Viren geschädigt und zerstört werden. Somit können sich Keime, Bakterien oder Viren nicht im Wundbereich ausbilden. Gleiches gilt für Milben oder Pilze, deren Wachstum bzw. Zellteilung ebenfalls durch anorganische Ionen gehemmt bis nahezu gänzlich verhindert wird. Bevorzugt weist die Kunstfaser des Gewebematerialgemisches wenigstens eine anorganische Verbindung, bevorzugt metallische Verbindung, auf. Bei einer weiteren vorteilhaften Ausführungsform sind das erste Schichtmaterial und das zweite Schichtmaterial zumindest teilweise aneinander fixiert. Dies ist vorteilhaft, da somit Kammerelemente ausgebildet sind, welche ein Kammervolumen aufspannen und somit als Polster dienen.
Bei einer weiteren vorteilhaften Ausführungsform ist die Fixierung der beiden Schichtmaterialien wabenartig und/oder zwiebelmusterartig ausgebildet. Dies erweist sich als vorteilhaft, da durch die speziell ausgebildete Geometrie der Fixierung, welche bevorzugt als Absteppung ausgebildet ist, so dass durch die zwischen den Schichtmaterialien angeordnete Materiallage 5 und der Absteppung ein Polstereffekt bedingt wird. In a further advantageous embodiment, the composite material is growth-inhibiting with respect to germs, bacteria, viruses, mites and / or fungi and / or a combination thereof. This growth-inhibiting formation of the composite material takes place by the use of inorganic ions, preferably metal cations, more preferably silver ions, so that the cells of, for example, germs, bacteria or viruses are damaged and destroyed. Thus, germs, bacteria or viruses can not form in the wound area. The same applies to mites or fungi whose growth or cell division is also inhibited by inorganic ions to almost completely prevented. The synthetic fiber of the fabric material mixture preferably has at least one inorganic compound, preferably a metallic compound. In a further advantageous embodiment, the first layer material and the second layer material are at least partially fixed to one another. This is advantageous since chamber elements are thus formed, which span a chamber volume and thus serve as a cushion. In a further advantageous embodiment, the fixation of the two layer materials is honeycomb-like and / or bulb pattern-like. This proves to be advantageous because, due to the specially designed geometry of the fixation, which is preferably designed as stitching, so that a cushioning effect is caused by the material layer 5 arranged between the layer materials and the stitching.
Unter wabenartig ist hierbei die Geometrie der Kammerelemente in Form von bevorzugt sechseckigen Elementen zu verstehen, welche in einer hexagonaldichtesten Packung angeordnet sind. Dies ist von Vorteil, da somit eine Vielzahl von Kammerelementen ausbildbar ist, i 10 welche einen polsternden Effekt aufweisen. Mehr bevorzugt weisen die wabenartigen, Kammerelemente in ihrer Längsrichtung eine Ausdehnung von 2 - 15 cm, bevorzugt von 8 - 13 cm, auf und in ihrer Breite, welche senkrecht zur Längsrichtung ausgebildet ist, eine Ausdehnung im Bereich von 1 - 15 cm, bevorzugt von 7 - 12 cm. Unter Längsrichtung der wabenartigen Kammerelemente ist die Richtung zu verstehen, in welcher die wabenartigen 15 Elemente ihre längste geometrische Ausdehnung aufweisen. Under honeycomb this is the geometry of the chamber elements in the form of preferably hexagonal elements to understand, which are arranged in a hexagonaldichtesten pack. This is advantageous since a multiplicity of chamber elements can thus be formed, which have a cushioning effect. More preferably, the honeycomb-like, chamber elements in their longitudinal direction an extent of 2-15 cm, preferably from 8-13 cm, on and in its width, which is perpendicular to the longitudinal direction, an extension in the range of 1-15 cm, preferably from 7-12 cm. The longitudinal direction of the honeycomb chamber elements is to be understood as the direction in which the honeycomb elements have their longest geometric extension.
Bevorzugt erfolgt die Fixierung der beiden Schichtmaterialien sowie der dazwischen angeordneten Materiallage bevorzugt durch Absteppung oder Vernähen, welches maschinell und/oder manuell erfolgt. Preferably, the fixing of the two layer materials and the material layer arranged therebetween preferably takes place by stitching or sewing, which takes place mechanically and / or manually.
