Claims (14)
1. Ensartet sårforbinding omfattende: en absorberende kerne, et bagsidelag og et vævet eller ikke-vævet stoflag, omfattende et middel med en virkning mod patogen mikrobiel kolonisering af et sår, hvor det vævede eller ikke-vævede stoflag er forbundet med mindst en del af randdelen i forhold til den proksimale overflade af bagsidelaget, der grænser op til midterdelen, hvor det ikke-vævede eller vævede stof ikke er forbundet med den absorberende kerne, hvilken sårforbinding endvidere omfatter et bærerlag, der er fastgjort til det vævede eller ikke-vævede stof i mindst en del af randdelen deraf og har mindst en åbning, gennem hvilken fluid kan passere fra såret til den absorberende kerne.
2. Sårforbinding ifølge krav 1, hvor det vævede eller ikke-vævede stoflag er fastgjort til den samlede del af den proksimale overflade af bagsidelagets randdel.
3. Sårforbinding ifølge krav 1, hvor bærerlaget omfatter en polyurethanfilm, der kan tilpasse sig.
4. Sårforbinding ifølge et af de foregående krav, hvor sårforbindingen omfatter et hudklæbende lag, der er anbragt i randdelen af dens proksimale side.
5. Sårforbinding ifølge krav 4, hvor det hudklæbende lag omfatter et silikonemateriale, fortrinsvis en silikonegel.
6. Sårforbinding ifølge et af de foregående krav, hvor bagsidelaget omfatter et vanduigennemtrængeligt dampgennemtrængeligt lag, fortrinsvis en polyurethanfilm, der kan tilpasse sig.
7. Sårforbinding ifølge et af de foregående krav, hvor det vævede eller ikke-vævede stoflag, der omfatter et middel med en virkning mod patogen mikro biel kolonisering af et sår, omfatter et celluloseacetattekstil eller et bomuldstekstil, der er blevet behandlet med dialkyl-carbamoylchlorid for at give stoffet en stærk hydrofob egenskab.
8. Sårforbinding ifølge et af de foregående krav, hvor det vævede eller ikke-vævede stoflag, der omfatter et middel med en virkning mod patogen mikrobiel kolonisering af et sår, omfatter et stoflag, som bærer mindst et antimikro-bielt middel, der er valgt fra gruppen bestående af kobber, sølv, sølvsalte, jod, povidonjod, chlorhexidin, chlorhexidinsalte, polyhexamethylenbiguanid, polyhexamethylenbiguanidsalte, kvaternære ammoniumsalte og kombinationer deraf.
9. Sårforbinding ifølge krav 8, hvor det mindst ene antimikrobielle middel er frigørligt inkorporeret i stoffet.

11. Sårforbinding ifølge et af de foregående krav, hvor den absorberende kerne omfatter en række optagelser, der er tilvejebragt i den distale overflade og er fyldt med superabsorberende partikler.
12. Sårforbinding ifølge et af de foregående krav, hvor den absorberende kerne omfatter et fastholdelseslag, der er fyldt med superabsorberende materiale.
13. Sårforbinding ifølge et af de foregående krav til anvendelse i en fremgangsmåde til behandling af et sår.
14. Fremgangsmåde til fremstilling af en sårforbinding ifølge et af kravene 1 til 12, omfattende de følgende trin: a) at tilvejebringe et bærerlag; b) at påføre en overfladebehandlingssubstans eller en primer, der er opløst i et opløsningsmiddel, på den proksimale overflade af bærerlaget; c) at afdampe opløsningsmidlet, hvis der anvendes en primer, der er opløst i et opløsningsmiddel; d) at ekstrudere et lag af ikke-hærdet silikonegel homogent på den primerbehandlede proksimale overflade af bærerlaget; e) at hærde den ikke-hærdede silikonegel ved opvarmning af silikone-gelprækursoren; f) at fjerne midterdelen fra bærerlaget; g) at påføre det behandlede stoflag over den distale overflade af bærerlaget; h) at anbringe den absorberende kerne over det behandlede stoflag, der er centreret over åbningen i bærerlaget; i) at anbringe et bagsidelag over de distale overflader af den absorberende kerne og bærerlaget; j) at forbinde lagene termisk.
