Diagnostic Kit Instructions - OHIO WILLOW WOOD LimbLogic VS Series Prosthetist's Manual

Diagnostic Kit Instructions

The following process can be used to evaluate the integrity of the system prior to fitting or to iso-
late the source of a leak in a system fabricated with the LimbLogic VS 4-Hole Attachment Plate.
Start HERE if the leak is found AFTER
the prosthesis has been delivered.
Have the patient don the prosthesis:
• fold down the top edge of the Alpha Liner
• use a latex sleeve from the kit instead of the
Alpha Flex
Activate the vacuum.
If the leak goes away, the Alpha Flex was the
source.
The leak was coming from between the adapter and
the socket or through the socket walls.
Check socket fabrication against Ohio Willow Wood's
recommendations.
Please note: if an intermittent leak is detected during
dynamic alignment, drill the center hole out to 3/8",
fill the hole with epoxy, then drill a new 9/32" hole in
the center.
The leak was coming from the proximal
sealing gasket.
Check gasket for tear or debris. Clean
with opropyl alcohol.
Install a new Proximal Gasket.
Reassemble the prosthesis.
Have the patient don the prosthesis with a latex sleeve from the
kit instead of the Alpha Flex.
Activate the vacuum.
If the leak goes away, the leak was coming from the Alpha
Flex or from the walls of the drilled hole.
If the drilled hole is the source:
• drill the hole out to 3/8", fill the hole with epoxy, then drill
a new 9/32" hole in the center.

• Remove the protective tape from the Diagnostic Disc.
• Place the Proximal Gasket in the recess on top of the
pump.
• Place the Diagnostic Disc on top of the Proximal
Gasket.
• Start the pump and make sure the vacuum does not
bleed off.
