Die Hautpflaster für medizinische Zwecke weisen üblicherweise klebende Flächen auf Basis von Kautschuk-Harzen oder von Polyacrylaten auf. The skin patch for medical purposes typically have adhesive surfaces on the basis of rubber resins or polyacrylates. The pavement with rubber adhesive surfaces have the disadvantage that difficult to remove residue left on the skin when the patch is removed again.

In addition, these patches often cause skin irritation. Die Nachteile von Pflastern mit Haftflächen auf Polyacrylat-Basis liegen in den teilweise auftretenden Hautrötungen bis zu Hautreizungen und in den Hauterweichungsprozessen, die sich allgemein bei ungenügendem Luftzutritt zeigen. The disadvantages of patches with adhesive surfaces based on polyacrylate are in the partially occurring redness to skin irritation and in the Hauterweichungsprozessen which generally show up in insufficient air access.

These disadvantages are particularly to occur when polyacrylate adhesive surfaces are more than a Wunden Corns on the skin and even if the area covered by the adhesive surface has a larger extent.

It has now been found that one obtains self-adhesive fabric which adhere well on rough and uneven surfaces, virtually residue-free removable and additionally are tolerated by the skin when coating arbitrary substrates with a polyurethane reaction mixture that hardens to form a solid structure, highly elastic gel.

The stated averages of molecular weight and OH number are to be understood as a number average. The invention finally, the use of self-adhesive fabric in medicine, Wunden Corns, particularly as Wunden Corns or adhesive plaster, bandage or gauze. The fabrics of the invention can be prepared by methods known per se from Wunden Corns starting compounds known from polyurethane chemistry, as described for example in DE-OS 3, and DE-OS 3, It is essential, however, that the selection of the gel-forming components above-defined conditions are met, otherwise non-tacky instead of self-adhesive gel layers, elastic gels are obtained.

According to preferred polyhydroxy compounds are polyether polyols, such as are mentioned in detail in the obep mentioned German published patent applications. Als Polyisocyanatkomponente sind sowohl cyclo aliphatische als auch aromatische Isocyanate geeignet. As the polyisocyanate component in both cyclo aliphatic and aromatic isocyanates are useful. Bevorzugte cyclo aliphatische Polyisocyanate sind 1,6-Hexamethylen-diisocyanat sowie dessen Biurete und Trimerisate bzw.

Preferred cyclo aliphatic polyisocyanates are 1,6-hexamethylene diisocyanate and its biurets and trimers and hydrogenated diphenylmethane diisocyanate "MDI" - types. Preferred aromatic polyisocyanates are those obtained by distillation, such as MDI mixtures of 4,4'- and 2,4'-isomers, or 4,4'-MDI and toluene diisocyanate "TDI" - type.

Weiterhin können als flüssige Streckmittel auch höhermolekulare Polyole eingesetzt werden deren Hydroxylgruppen verethert, verestert oder urethanisiert sind, sowie Paraffinöle und Silikonöle. Further, as liquid extenders high molecular weight polyols whose hydroxyl groups are used etherified, urethanized or esterified, as well as paraffin oils and silicone oils. The amount of fillers and extenders in the gel layer can be up to 50 wt, Wunden Corns.

Zur Modifizierung der Hafteigenschaften der Gelschicht können gegebenenfalls Zusätze von polymeren Vinylverbindungen, Polyacrylaten und sonstigen in der Klebstoff-Technik üblichen Copolymeren bzw.

To modify the adhesive properties of the gel layer may optionally additions of polymeric vinyl compounds, polyacrylates and other in the adhesive art conventional copolymers or also adhesive based Wunden Corns natural substances up to a content of 10 wt.

Die Schichtdicke des Gels kann z. The layer thickness of the gel can be, Wunden Corns. The support materials contained in the self-adhesive sheet materials according Wunden Corns the invention can be of different origin, Wunden Corns, ie materials based Wunden Corns natural, semi or fully synthetic raw materials, and organic or Wunden Corns origin are used.

For Wunden Corns, can be used plastic and metal foils, mats, non-wovens, knits or fabric of organic or inorganic fiber material, paper, cardboard, wood, Wunden Corns, leather and foam films or combinations of these support materials. Für die medizinische Anwendung bevorzugt sind luft- und feuchtigkeitsdurchlässige Flächengebilde, Wunden Corns mikro- und makroporöse Kunststoffolien, elastische textile Trägermaterialien, insbesondere Stretchgewebe, und Mullbinden.

Preferred for medical application are air- and moisture-permeable sheet, such as micro- and macro-porous plastic, elastic textile backing materials, especially stretch fabric, and gauze bandages. The preparation of the gels contained in the fabrics Wunden Corns to the invention can be carried out in various ways, Wunden Corns. Man kann zB nach dem one-shot- oder dem Prepolymer-Verfahren arbeiten. You can work, for example, by the one-shot or prepolymer process.

Beim Prepolymer-Verfahren sind zwei Arbeitsweisen möglich. In the prepolymer process, two procedures are possible. Entweder stellt man zunächst ein Isocyanat-Prepolymer her, indem man einen entsprechenden Anteil der Polyolmenge Wunden Corns der gesamten, für die Gelbildung Speiseröhre Thrombophlebitis Isocyanatmenge umsetzt, und fügt dann dem erhaltenen Prepolymer die restliche Menge an Polyol sowie gegebenenfalls Füll- und Zusatzstoffen zu und mischt intensiv.

Either one first sets isocyanate prepolymer is prepared by reacting a corresponding proportion of the polyol with the whole, intended for the gel formation of isocyanate, and then added to the prepolymer obtained, the remaining amount of polyol and, Wunden Corns, where appropriate, fillers and additives to make and mixed thoroughly.

Or are employed the entire, provided for the amount of polyol gel formation with a portion of the isocyanate to a hydroxyl-prepolymer and then mixed to the remaining amount of isocyanate to, Wunden Corns. One inventively particularly advantageous procedure is a variant of the one-shot process and the hydroxyl-prepolymer process. Hierbei werden das Polyol bzw. Here, the polyol or polyol mixture, where appropriate, the fillers and additives, catalyst, and two different diisocyanates are combined in one shot and mixed thoroughly to give a diisocyanate Wunden Corns an aromatic diisocyanate is aliphatic.

It can be assumed that initially a Hydroxylprepolymer created through the different reactivity of the two diisocyanates, which then reacts within minutes with the other diisocyanate to form a gel.

Bei diesen Verfahrensweisen kann die Förderung, Dosierung und Mischung der Einzelkomponenten oder Komponentengemische mit den für den Fachmann in der Polyurethan-Chemie an sich bekannten Vorrichtungen erfolgen. In these procedures the conveying, metering and mixing of the individual components or component mixtures with the devices known to those skilled in polyurethane chemistry which can be carried out. The preparation of the fabrics of the invention can be carried out continuously or discontinuously.

Die Arbeitsweise hängt von den vorgegebenen, mit einer Haftschicht zu versehenden Flächengebilden ab, Wunden Corns. The procedure depends on the set, Wunden Corns, with an adhesive layer Wunden Corns be provided fabrics.

Wenn man bereits zugeschnittene Trägermaterialien vorliegen hat, ist oftmals eine diskontinuierliche Arbeitsweise vorteilhaft. If you are already tailored support materials, a discontinuous mode of Wunden Corns is often advantageous. Die kontinuierliche Arbeitsweise empfiehlt sich bei der Beschichtung von Trägermaterialien, die in endloser Form, zB als Rollenware, vorliegen.

The continuous procedure is advisable for coating substrates, which are present in continuous form, eg rolls. Der Auftrag der gelartigen Haftschicht auf das Trägermaterial kann dabei direkt oder nach dem Umkehrverfahren erfolgen. The mission of the gel-like adhesive layer on the support material may be direct or by the reversal process, Wunden Corns. The gellable reaction mixture can be said processes is also before it solidifies, doctoring or spraying by the reaction.

Das Sprühverfahren ermöglicht zB die Varizen es Salbe, punktuelle Beschichtung von grobmaschigen Geweben. The spraying allows for example the simple, selective coating of coarse mesh fabrics. An advantageous treatment of the fabrics of the invention is irradiation with gamma rays, whereby the adhesiveness of the gel layer is improved, Wunden Corns, that is, the adhesive strength of the sheet with respect to any desired substrates is increased, Wunden Corns.

A significant advantage of the fabrics of the invention in the application as medical tape is the good skin compatibility. Es zeigen sich keine Mazerationen oder sonstige durch Luft- und Wasserdampfundurchlässigkeit hervorgerufene Hautschäden, Wunden Corns. Shown are no maceration or other by air and water vapor permeability induced skin damage. Moreover sheet of the invention can replace a plaster virtually residue-free and with a slight train back from the skin without hair removal occurs.

A particular embodiment of the fabrics of the invention thus provide wound dressings is composed of an a self-adhesive polyurethane gel containing substrate on which a wound pad is positioned centrally to complete wound to the sides all around.
