Linda,
Ameda Egnell/Hollister makes a soft silicone insert for the pump shell,
called a flexishield.  Perhaps inserting a flexishield into the breast
cup would allow this mom to pump without the dermatitis.  They do fit in
Medela kits as well, but are a little long for Medela's nipple tunnel
which can necessitate tipping the kit periodically to allow the milk to
drain into the bottle.  They work perfectly in the Ameda kits.
Hollister's 800 number in USA is 800 323-4060.
