Hello colleagues,
Thanks for all the responses. Most of you suggested inverting the proximal edge of the liner. This of course requires a liner that is long enough but it always leaves a think edge, especially with a 9mm liner and that is also then prone to vacuum blistering. Some suggested using an ESP seal ring, ALPS scrap or even an Ossur seal ring glued to the proximal liner. In fact I did glue a scrap of inverted Willowwood gel sock to the proximal edge of the liner. It works intermittently possibly because it is very think and wrinkly. The most interesting response was “to poke a hole in the vacuum line to deactivate the elevated vacuum”. The most helpful responses included the possibility of slowly and carefully peeling the fabric off the proximal area of a new liner, starting at the tiny gap at the seam between different coloured fabric patches. Thanks again for the help (and the laughs),

We have trialled him in elevated vacuum (Harmony P3) which works very well except for the typical skin suction rash at the edge of the liner. An interim solution has been to use silicone adhesive to make the fabric proximal portion of the liner airtight but this only works intermittently. The WillowWood One liner would be ideal but its also only 6mm. Any other brilliant solutions or suggestions other than a recast of the socket over a 6mm One liner?
