Europäische Patentanmeldung 83850090.8 Astra Meditec AB P a te η t an s prü ch e
1. Verfahren zur Aufbringung eines hydrophilen Überzuges, der einen niedrigen Reibungskoeffizienten hat, wenn er mit einer Flüssigkeit auf Wasserbasis befeuchtet wird, auf einer Poiymeroberflache, indem man auf die Polymeroberfläche eine Lösung aufbringt, die zwischen 0,05 und 40 % (Gewicht je Volumen) einer Verbindung, die wenigstens zwei unumgesetzte Isocyanatgruppen je Molekül umfaßt, enthält, das Lösungsmittel verdampft, eine zwischen 0,5 und 50 %(Gewicht je Volumen) Polyvinylpyrrolidon enthaltende Lösung auf der so behandelten Polymeroberfläche aufbringt und sodann das Lösungsmittel der letztgenamten Lösung verdampft und den Überzug bei erhöhter Temperatur härtet.
2. Verfahren nach Anspruch 1, dadurch gekennzeichnet, daß die Polyvinylpyrrolidonlösung oder die Isocyanatlösung einen Katalysator enthält, der die Härtung des Isocyanats beschleunigt.
3. Verfahren nach Anspruch 2,· dadurch gekennzeichnet, daß der Katalysator ein Amin, vorzugsweise ein Diamin oder Triethylendiamin, umfaßt.
4. Verfahren nach Anspruch 1 bis 3, dadurch gekennzeichnet, daß die Isocyanatlösung ein Polymer enthält, das die Isocyanatdiffusion vor dem Härten des Überzuges vermindern soll.
5. Verfahren nach Anspruch 4, dadurch gekennzeichnet, daß das Polymer in der Isocyanatlösung aus der Gruppe der
Polyester, Polyvinylverbxndungen, Polyurethane, Polyisocyanate oder Copolymere dieser. Verbindungen ausgewählt ist.
6. Verfahren nach Anspruch 1, dadurch gekennzeichnet, daß das abschließende Härten in Gegenwart eines wasserhaltigen Gases durchgeführt wird.
7. Verfahren nach Anspruch 1, dadurch gekennzeichnet, daß die zu beschichtende Polymeroberfläche ein ,- Polymer
aus der Gruppe Latex, Polyvinylchlorid und Polyurethan umfaßt.
8. Verfahren nach Anspruch 1, dadurch gekennzeichnet, daß der erhaltene hydrophile Überzug durch Behandlung mit
Jod antibakteriell gemacht wird.
9. Medizinischer Gegenstand für das Einführen in den Körper, dadurch gekennzeichnet, daß der Gegenstand mit einem
gemäß den Ansprüchen 1 bis 8 hergestellten hydrophilen Überzug versehen ist.
10. Medizinischer Gegenstand nach Anspruch 9, dadurch gekennzeichnet, daß er ein Katheter ist.
