Claims (13)
1. Sårforbindingsmateriale med et dækelement til optagelse af sårsekret eller til påføring af sårhelingsfremmende midler og en kontaktside til at lægge på såret, kendetegnet ved, - at kontaktsiden er dannet af et biokompatibelt monofilamentstof af monofi-lamenttråde af PET med en glat stabil overflade, - at PET-monofilamenttrådene har en diameterstørrelse på mellem 20 pm til 500 pm, og - at monofilamentstoffet er udformet som et bærelag med en overside, der vender bort fra såret, hvorpå dækelementet er påført og områdevist er fast forbundet med bærelaget ved hjælp af punktsvejsning.
2. Sårforbindingsmateriale ifølge krav 1, kendetegnet ved, at monofilamentstoffet er udformet som et enkeltvævet stof med åbenmasket struktur, der har en porestørrelse på 5 pm til 500 pm, fortrinsvis 20 pm til 300 pm, og at porerne udgør en andel på 15 % til 60 % af monofilamentstoffets flade.
3. Sårforbindingsmateriale ifølge krav 1 eller 2, kendetegnet ved, at monofilamentstoffets monofilamenttråde har en diameterstørrelse på mellem 50 pm til 150 pm.
4. Sårforbindingsmateriale ifølge et af kravene 1 til 3, kendetegnet ved, at kontaktsiden i det mindste områdevist er forsynet med et klæbelag.
5. Sårforbindingsmateriale ifølge krav 4, kendetegnet ved, at klæbelaget er påført strimmelformet langs et kantområde af monofilamentstoffets kontaktside, og at monofilamentstoffets kantområdes overside, der vender bort fra kontakt siden, holdes fri fra dækelementet.
6. Sårforbindingsmateriale ifølge et af kravene 1 til 5, kendetegnet ved, at dækelementet omfatter et stof, et non-woven-tekstil, en folie, en membran og/eller et skum.
7. Sårforbindingsmateriale ifølge et af kravene 1 til 6, kendetegnet ved, at dækelementet er punktsvejset med monofilamentstoffet ved hjælp af ultralydssvejsning.
8. Sårforbindingsmateriale ifølge et af kravene 1 til 7, kendetegnet ved, at dækelementet omfatter et ydre dæklag, der er forbundet med monofilament-stoffet ved dannelse af mindst et optagelsesområde.
9. Sårforbindingsmateriale ifølge et af kravene 1 til 8, kendetegnet ved, at tykkelsen af oversiden, der er dannet af dækelementet, udgør 60 % til 98 % af sårforbindingsmaterialets samlede tykkelse.
10. Sårforbindingsmateriale ifølge et af kravene 1 til 9, kendetegnet ved, at dækelementet omfatter en plejende eller medicinsk effektiv substans.
11. Sårforbindingsmateriale ifølge et af kravene 1 til 10, kendetegnet ved, at monofilamentstoffet eller monofilamenttrådene, der danner monofilamentstof-fet, er forsynet med en coating.
12. Sårforbindingsmateriale ifølge et af kravene 1 til 11, kendetegnet ved, at monofilamentstoffet er vævet med en ensartet defineret porestørrelse, hvor porestørrelserne ikke afviger mere end 10 % fra hinanden.
13. Fremgangsmåde til fremstilling af et sårforbindingsmateriale ifølge et af kravene 1 til 12, hvor - et biokompatibelt monofilamentstof af monofilamenttråde af PET med en glat stabil overflade dannes som et første banemateriale, hvor PET-monofilamenttrådene har en diameterstørrelse på mellem 20 pm til 500 pm, - et dækelement dannes som et andet banemateriale, - det første banemateriale og det andet banemateriale føres sammen, hvor det biokompatible monofilamentstof tilvejebringes som et bærelag med en overside, der vender bort fra såret, og hvorpå dækelementet påføres og ved hjælp af punktsvejsning forbindes fast med bærelaget, og - sårforbindingsmaterialet fremstilles som et bånd.
