Hi all, just trying to find a better upper extremity valve and was wondering what others were using. I am working with a AE patient who can't seem to keep vacuum. I have used SFS, and USMC two part plastic valves with little luck. I am careful during fabrication to get a good seal but there is just enough of a leak to be a real pain in the but for him.
I am using a flexible socket in a rigid frame much like an AK prosthesis but being an AE he has all the weight of his prosthesis pulling down and no weight bearing moments to expel any air that gets in.
Any thoughts...
