Hi again Anita:
That feeling of you skin pulling away is what the prosthetists call a slow
leak through a "channel". The channel is minute (almost a virtual cavity)
but lets the air in just as efficient as a large hole. Every individual is
different but they tend to occur in the areas where the muscles have natural
fascial planes, where one muscle can slide over another muscle just a bit,
and the overlying skin and subcutanuos tisse can, in turn, slide along and
pull away from the flexible part of the socket. Although I've been a member
of this "club" only for a little more than 1 1/4 years I have snooped around
with my prosthetist, his partners and colleagues from several facilities in
Chicago. These slow "leaks" while changig position are a little bit of a
challenge to fix. Early on while I was still undergoing atrophy
(particularly the latera and postero/lateral mucles, because those are the
ones we, AK's don't use as much as extensors flexors and adductors) we (my
prosthetist and I) had a period of several weeks of trial and error with
those liners until he crafted the right liner to hold the vaccum just right,
witouth becoming too tight or uncomfortable.
Re: Self bleeding valve: According to my prosthetist, is a new model in the
market (they just found out about it about 6 - 8 months ago). I just took it
off the socket, but not a clue about the manufacturer on it. I you want,
I'll find out who is theis suplyer and let you know.
I hope this helps to figure out the source of the leak and fix it. Good
luck, I know, it IS anoying
