Hi Homie,
I often wonder what the impact is to the area of skin that is permanently covered by my appliance flange, particularly as it gets no natural air or light or vitamin D?
After showering daily and removing my used one-piece (flange and pouch), I avoid replacing it for as long as possible to enable the area under the flange to breathe in some air. I stay in the bathroom and usually get a window of time of around 15 minutes while my stoma is inactive and can carry on with grooming and clear up the bathroom, etc., after which time the skin has died too!
Personally, for me, it's important that the area of skin beneath my appliance gets some air, and it may be a coincidence; however, the area does remain healthy.
I did discuss my changing routine with my stoma nurse and without knowing anything about cups (until your posting) and attempted to describe a contraption design that I had in mind that would involve a small tray with elastic straps that could go around the waist and capture waste - she exclaimed enthusiastically that what I was describing was a pelican bib.
Will
