Hi, Herb, The Hollister flange which is the part that is on your skin that the bag attaches to (the system Jim uses is two piece)Edgepark Item #51125276 I think if you enter that number in the search you will find the specific flange. It has a matching bag number #51401545. It seems that the larger area being covered has helped Jim plus the part that attaches to your tummy is a paper like material that doesn't seem to irritate his skin. The Eakins that Jim has are rings Edgepark item#51839002. The Eakins seals are stretched to a size that is just about 1/4" beyond the largest edge of the stoma area. Jim is using a precut 1 5/8" flange so his Eakins is made just about 1/4" larger than the 1 5/8" opening in the flange. He applies it to the flange so that once his skin is prepped with the barrier adhesive wipes etc he can just put the entire flange, eakins on it right onto the belly over the stoma area. I know this may sound confusing and i wish I could draw what I am trying to tell you. Basically we make the flange and Eakins into one piece then apply it to the belly around the stoma leaving that approx 1/4" distance around the perimeter of the stoma or "innie". Hold it in place for a moment BTW, put a 4x4 gauze square over the opening as we all know they start squirting at inopportune moments! Then take the paper backing off the flange and hold it in place until it sticks well. Once this is done, apply the bag. It sounds MUCH more complicated than it is. Since we've used the Eakins and the skin cleaning method no more sores/raw areas etc plus the newer precut flange with the paper backing. BTW, check what size precut you need when you order. Jim uses the size above which comes in red boxes. Herb, this is all a big learning process for all of us and I know you will do fine. It just frustrates when you can't get the right size, or leaks etc. I hope this helped some. If not private message me and we can find a way to get more info to you.
