Diagnostic Kit Instructions

Press the Suction

Pad against the

proximal surface of

the distal adapter

with the dome side

facing down.

Activate the vacuum.

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.

Press the Suction

Pad against the

proximal surface of

the distal adapter

with the dome side

facing up.

Activate the vacuum.

The leak

was coming

through the

socket walls.

Laminate a

new socket

with an inner

layer of

PETG.

To conrm that you have xed the leak:

• Reassemble the pump and gasket to the socket.

• Activate the vacuum.

• Make sure that there are two

Proximal Gaskets in place

between the pump and the

themoplastic socket.

• Make sure that the four M6

screws are tightened to 9

ft-lbs or 12 Nm.

• Make sure that the internal

surface of the thermoplastic

socket is at and free of

defects.

The leak was

coming from the

Vacuum Pump.

Contact Ohio

Willow Wood.

Follow this process to evaluate the integrity of the

LimbLogic VS prior to tting or to isolate the source

of a leak in the system.

The Alpha

Flex was the

source of the

leak.

Start HERE if the

leak is found AFTER

the prosthesis has

been delivered.

Renove the pump from the socket. Use the Diagnostic

Disc that is included with every pump to see if the leak is

coming from the pump:

• 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.

• Attach the pump with the Diagnostic Disc and

Proximal Gasket to the socket.

• Start the pump and make sure the vacuum does not

bleed off.

The leak is coming from where the socket meets the pump. Possible causes:

• The 4-Hole Distal Adapter was not attached to the socket using Fabtech 60 structural

urethane.

• The pump was installed with the wrong bolts. If the 55 mm bolts for the thermoplastic

adapter were used in a laminated socket, the bolts will bottom out before they can be

appropriately tightened.

• The leak could be coming from the proximal sealing gasket. Make sure the gasket is the

one that was provided by Ohio Willow Wood. Clean with isopropyl alcohol to remove

any debris. If the gasket is torn, install a new one.

• The surface of the 4-Hole Distal Adapter and/or pump are damaged or dirty.

• The walls of the center hole could be leaking. Drill the hole out to 3/8", ll the hole

with Fabtech 60 structural urethane, then drill out a new 9/32" hole.
