Hollister sizes

Hi everybody it's been about a year since I've had my ostomy I'm bleeding around my stoma on one side and I know the last time that happened the nurse made me go to a larger flange size so now I have to use the 70 mm I have the bags but I don't know the corresponding flange that fits on the bag number 18104 Hollister and does anyone know if there is an accordion Flange type with Hollister like convatec has thanks so much
