Description
Die Erfindung betrifft eine Wundauflage zur Versorgung vonThe invention relates to a wound dressing for the care of
Wunden-am menschlichen und tierischen Körper.Wounds on the human and animal body.
Es ist bekannt, in der Wundbehandlung anstelle von Zellstoffauflagen Auflagen aus Polyurethanschäumen auf die Wunden auf zu legen, die eine gewisse Saugwirkung auf die Wunden ausüben.It is known to be used in wound treatment instead of cellulose pads Padding made of polyurethane foams to be placed on the wounds, which have a certain suction effect exercise on the wounds.
Dadurch werden die Gewebeflüssigkeiten in diesem schaumstoffartigen Polyurethanschwamm aufgesogen, so daß die Heilerfolge gegenüber den bekannten Zellstoffauflagen wesentlich günstiger verlaufen.This causes the tissue fluids in this foam-like Polyurethane sponge soaked up, so that the healing success compared to the known cellulose pads run much cheaper.
Ähnlich wie bei den Zellstoff- und Kompressenauflagen bildet sich jedoch auch bei der Anwendung von Auflagen aus Polyurethanschäumen zwischen der Wundgranulation und dem Auflagepolster eine feste Verbindung, so daß beim Entfernen der Saugflächen es immer zu Wundbeschädigungen kommt.Similar to the pulp and compress pads forms but also when using polyurethane foam pads between the Wound granulation and the pad a firm connection, so that when removing wound damage always occurs on the suction surfaces.
Es ist daher Aufgabe der vorliegenden Erfindung, eine Wundauflage zu schaffen, mit der ein Verwachsen mit der Wundgranulation einer heilenden Wunde vermieden wird, die einen hohen Saug- und Speichereffekt für die bei Wunden am menschlichen und tierischen Körper auftretenden Gewebeflüssigkeiten aufweist und bei der die aufgesogene Gewebeflüssigkeit nicht bei Bewegung und Druck aus der Wundauflage herausdrückbar ist.It is therefore the object of the present invention to provide a wound dressing to create a healing wound that fuses with the wound granulation it avoids having a high suction and storage effect for wounds on human and tissue fluids occurring in the animal body and in which the Tissue fluid absorbed cannot be pressed out of the wound dressing during movement and pressure is.
Zur Lösung dieser Aufgabe wird eine Wundauflage vorgeschlagen, die erfindungsgemäß aus einer Saugschicht mit einem Kapillarwirkungseffekt aus einem geschäumten, additionsvernetzten Silicon-Kautschuk mit einer in der Saugschicht mit eingeschäumten Saug-Speicher-Schicht aus einem stark hygroskopisch wirkenden Material und aus einer die Saugschicht einseitig abdeckenden Abdichtschicht besteht.To solve this problem, a wound pad is proposed which according to the invention from an absorbent layer with a capillary effect the end a foamed, addition-crosslinked silicone rubber with one in the absorbent layer with foamed-in suction storage layer made of a strongly hygroscopic acting Material and consists of a sealing layer covering one side of the absorbent layer.
Die Saug-Speicher-Schicht ist in Form von streifenförmigen Abschnitten, als perlenformartige Körper oder gitterartig in die Saugschicht mit eingeschäumt und besteht aus stark hygroskopisch wirkendem Material, wie z.B. Zellstoff od.dgl..The suction-storage layer is in the form of strip-shaped sections, foamed into the absorbent layer as a bead-like body or in a grid-like manner and consists of strongly hygroscopic material, such as cellulose or the like.
Mit einer derart ausgebildeten Wundauflage ist die Bildung einer festen Verbindung der Wundauflage mit der Wundgranulation einer Wunde nicht mehr möglich, so daß bei einem Entfernen der Wundauflage keine Wundenbeschädigung mehr eintreten kann.With a wound pad designed in this way, the formation of a firm one is possible Connection of the wound dressing with the wound granulation of a wound is no longer possible, so that no more damage to the wound occurs when the wound dressing is removed can.
Dies ist auf die verwendete Saugschicht aus additionsvernetztem Silicon-Kautschuk zurückzuführen, der eine toxikologische Unbedenklichkeit aufweist, die wesentlich höher liegt als die bekannten als Wundauflagen verwendeten Polyurethanschäume.This is due to the addition-crosslinked silicone rubber absorbent layer used attributable, which has a toxicological harmlessness, which is essential higher than the known polyurethane foams used as wound dressings.
Additionsvernetzter Silicon-Kautschuk wird vom Körpergewebe nicht angenommen, d.h. ein Verwachsen der Wundauflage mit der Wunde, d.h. mit der Wundgranulation,ist nicht mehr gegeben.Addition-crosslinked silicone rubber is not absorbed by the body tissue assumed, i.e. the wound dressing has grown together with the wound, i.e. with the wound granulation no longer given.
Daraus ergibt sich, daß Wundauflagen mit einer Saugschicht aus einem geschäumten, additionsvernetzten Silicon-Kautschuk ideale Voraussetzungen für die Wundheilung ergeben.It follows that wound dressings with an absorbent layer from one foamed, addition-crosslinked silicone rubber ideal conditions for Result in wound healing.
Durch die Verwendung von geschäumtem, additionsvernetztem Silicon-Kautschuk als- Saugschicht wird die Saugschicht mit einem Kapillarwirkungseffekt versehen, der ein Aufsaugen der Gewebeflüssigkeit aus der Wunde ermöglicht. Diese Gewebeflüssigkeit wird durch die in der Saugschicht ausgebildeten Kapillarkanälchen bis in die Saug-Speicher-Schicht befördert, die aus einem stark hygroskopisch wirkenden Material besteht und somit die Eigenschaft hat, die Flüssigkeit aufzusaugen und zu speichern mit der Folge, daß bei der Ausübung eines Druckes auf die Saugschicht Gewebeflüssigkeit nicht heraustreten kann, da diese von der Saug-Speicher-Schicht aufgesogen und in dieser Schicht festgehalten wird. Durch das in der Saugschicht ausgebildete Kapillar-Wirkungs-System nimmt diese eine bestimmte Menge Gewebeflüssigkeit auf, die jedoch bei Bewegung und Druck nicht aus dem als Schwamm wirkenden Kompressionsteil herausgedrückt werden kann, da die Gewebeflüssigkeit von der Saug-Speicher-Schicht aufgenommen und in dieser festgehalten. wird.Through the use of foamed, addition-crosslinked silicone rubber as an absorbent layer, the absorbent layer is provided with a capillary effect, which enables the tissue fluid to be sucked out of the wound. This tissue fluid is through the capillary channels formed in the absorbent layer into the absorbent storage layer conveyed, which consists of a strongly hygroscopic material and thus has the property of absorbing and storing the liquid with the result, that tissue fluid does not come out when pressure is exerted on the absorbent layer can, since these are absorbed by the suction-storage layer and held in this layer will. The capillary action system formed in the absorbent layer reduces this a certain amount of tissue fluid, but not with movement and pressure can be pressed out of the compression part acting as a sponge, since the Tissue fluid is absorbed by the suction storage layer and retained in this. will.
Weitere vorteilhafte Ausgestaltungen der Erfindung gehen aus den Unteransprüchen hervor.Further advantageous refinements of the invention emerge from the subclaims emerged.
So sieht u.a. die Erfindung die Verwendung eines Funktionsteiles aus einer Saugschicht mit einem Kapillarwirkungseffekt aus einem geschäumten,additionsvernetzten Silicon-Kauthuk mit einer in der Saugschicht mit eingeschäumten, streifenförmig,gitterförmig, flächenmäßig oder perlformartig ausgebildeten Saug-Speicher-Schicht aus einem stark hygroskopisch wirkenden Material und aus einer die Saugschicht einseitig abdeckenden Abdichtschicht als nicht mit dem Körpergewebe verwachsende Wundauflage mit einem hohen Saug- und Speichereffekt für die bei Wunden am menschlichen und tierischen Körper auftretende Gewebeflüssigke zwecks Verbesserung der Wundheilung vor.This is how the invention looks, among other things, to the use of a functional part an absorbent layer with a capillary effect made of a foamed, addition-crosslinked Silicone rubber with a foam layer in the absorbent layer, strip-shaped, grid-shaped, Areal or bead-like suction storage layer made of a strong hygroscopic material and from one the absorbent layer on one side covering sealing layer as a wound pad that does not grow together with the body tissue with a high suction and storage effect for wounds on human and Tissue fluids occurring in the animal body for the purpose of improving wound healing before.
In der Zeichnung ist der Gegenstand der Erfindung beispielsweise dargestellt, und zwar zeigt Fig. 1 eine kissenförmig ausgebildete Wundauflage in einer Ansicht von oben und Fig. 2 einen senkrechten Schnitt gemäß Linie II-II in Fig. 1 in einer vergrößerten Wiedergabe.In the drawing, the object of the invention is shown, for example, namely, Fig. 1 shows a cushion-shaped wound dressing in a view from above and FIG. 2 shows a vertical section along line II-II in FIG. 1 in one enlarged playback.
Die beispielsweise in Form eines Kissens 10 ausgebildete Wundauflage 100 besteht gemäß Fig. 1 und 2 aus einer Saugschicht 20 aus einem geschäumten,additionsvernetzten Silicon-Kautschuk, der der Saugschicht 20 einen Kapillarwirkungseffekt verleiht.The wound pad, designed for example in the form of a pillow 10 100 consists according to FIGS. 1 and 2 of an absorbent layer 20 made of a foamed, addition-crosslinked one Silicone rubber, which gives the absorbent layer 20 a capillary effect.
Dieser Kapillarwirkungseffekt wird bei der Verwendung eines geschäumten , additionsvernetzten Silicon-Kautschuks erhalten,jed besteht auch die Möglichkeit, einen additionsvernetzten Silicon Kautschuk-Schaum zu verwenden, in dem feinste, nebeneinander an ordnete Kapillar-Röhrchen ausgebildet sind, so daß aufgrund der Kapillarwirkung bei dünnen Röhrchen ein Saugeffekt erhalten wir, Diese saugfähigen Kapillarkanälchen bzw. -röhrchen sind in Fig. 2 bei 25 angedeutet.This capillary effect is when using a foamed , addition-crosslinked silicone rubber, but there is also the possibility of to use an addition-crosslinked silicone rubber foam in which the finest, side by side on arranged capillary tubes are formed, so that due to the Capillary action with thin tubes we get a suction effect, these absorbent Capillary tubules or tubes are indicated at 25 in FIG. 2.
Mit in die Saugschicht 20 ist eine Saug-Speicher-Schicht 30 mit eingeschäumt, die aus einem stark hygroskopisch wirkenden Material, wie z.B. Zellstoff od.dgl. besteht, wobei jedoch auch andere Stoffe und chemische Verbindungen verwendet werden können, die stark hygroskopisch wirkende Eigenschaften aufweisen. Die Saug-Speicher-Schicht 30 ist in die Saugschicht 20 beispielsweise in Form von streifenförmigen Abschnitten 30a integriert, wobei es vorteilhaft ist, diese Saug-Speicher-Schicht 30 im Randbereich der Saugschicht 20 anzuordnen, worauf nachstehei noch näher eingegangen wird. Anstelle von streifenförmigen Abschnitten 30a kann die Saug-Speicher-Schicht 30 aus perlformartige Körpern 30b bestehen, die über den Innenraum der Saugschicht 20 verteilt in dieser mit eingeschäumt sind. Auch eine flächenmäßige Ausbildung, beispielsweise in Form einer Zwischenschicht, mit Saug- und Speicherschichteigenschaften ist möglich. Darüber hinaus können auch gitterförmig ausgebildete Saug-Speicher-Schichten verwendet werden, wobei das Gitter dann ebenfalls aus stark hygroskopisch wirkendem Material besteht.A suction storage layer 30 is also foamed into the absorbent layer 20, made of a strongly hygroscopic material, such as cellulose or the like. exists, but other substances and chemical compounds are also used that have strongly hygroscopic properties. The suction storage layer 30 is in the absorbent layer 20, for example in the form of strip-shaped sections 30a integrated, whereby it is advantageous to have this suction storage layer 30 in the edge area to arrange the absorbent layer 20, which will be discussed in more detail below. Instead of of strip-shaped sections 30a, the suction-storage layer 30 can be made of pearl-shaped Bodies 30b exist, which are distributed over the interior of the absorbent layer 20 in this are foamed with. Also a planar design, for example in shape An intermediate layer with absorbent and storage layer properties is possible. About that In addition, grid-shaped suction storage layers can also be used, the grid then also consists of a strongly hygroscopic material.
Die Saugschicht 20 der Wundauflage 100 ist einseitig mit einer Abdichtschicht 40 abgedeckt, die den Innenraum der Saugschicht 20 außenseitig abdichtet. Diese Abdichtschicht 40 besteht vorzugsweise ebenfalls aus additionsvernetztem,homogenem Silicon, wodurch die Wirkung des Saugmaterials noch wesentlich ver--ht, bessert wird. Die Saug-Speicher-Schicht 30 ist dann in der Saugschicht 20 benachbart zur Abdichtschicht 40 angeordnet, wobei die Abdichtschicht 40 den äußeren Abschluß der Wundauflage darstellt. Diese Abdichtschicht bzw. -haut 40 und die Saugschicht 20 sind über eine bei 50 in Fig. 1 angedeutete Verzapfung miteinander verbunden.The absorbent layer 20 of the wound pad 100 has a sealing layer on one side 40 covered, which seals the interior of the absorbent layer 20 on the outside. These Sealing layer 40 preferably also consists of addition-crosslinked, homogeneous one Silicone, which significantly reduces the effectiveness of the absorbent material, improves will. The suction storage layer 30 is then adjacent to the suction layer 20 Sealing layer 40 arranged, the sealing layer 40 being the outer end of the Wound pad represents. This sealing layer or skin 40 and the Absorbent layer 20 are connected to one another via a mortise indicated at 50 in FIG. 1 tied together.
Der Schwammeffekt der Saugschicht 20 ist in Fig. 2 bei 20a angedeutet.The sponge effect of the absorbent layer 20 is indicated in FIG. 2 at 20a.
Um den Saugeffekt der Saug-Speicher-Schicht 30 zu erhöhen kann in der Abdichtschicht 40 der Wundauflage ein Absaugventil 6 vorgesehen sein, so daß die Saug-Speicher-Schicht 30 mit einem leichten Vakuum versehen werden kann, was durch Verwendung z.B.In order to increase the suction effect of the suction storage layer 30, in the sealing layer 40 of the wound pad, a suction valve 6 can be provided so that the suction storage layer 30 can be provided with a slight vacuum, what by using e.g.
eines kleinen Gummiballes oder Gummikissens als Absaugventil 40 erhältlich ist, der mit in die Abdichtschicht 40 so eingearbeitet ist, daß er überhaupt nicht aufträgt (Fig.2). Durch Einwirkung eines Druckes auf den Gummiball oder -kissen und Aufhebung des Druckes wird nach erfolgter Uberführung des Gummiballes oder -kissens in seine . Ausgangsstellung das jeweils gewünschte Vakuum erzeugt. Aufgrund des vorgesehenen Rückschlagventils wird eine Verbindung zur Außenluft verhindert, so daß das ausgebildete Vakuum in der Saug-Speicher-Schicht 30 erhalten bleibt.a small rubber ball or rubber cushion available as suction valve 40 which is incorporated into the sealing layer 40 so that it is not at all applies (Fig. 2). By applying pressure to the rubber ball or cushion and the pressure is released after the rubber ball or cushion has been transferred in his . Starting position creates the vacuum required in each case. Because of the provided check valve prevents a connection to the outside air, so that the vacuum formed in the suction storage layer 30 is maintained.
