Iceross Clean&Simple Spray or equivalent.
FINISHING / LINER OPTIONS
Össur recommends that the device is used with an Iceross Seal-In
Precaution: Make sure the Flex-Foot sock does not interfere with the
device as it could compromise the function of the pump.
THE TUBE
The tube is the most sensitive part of the device, and special attention
should be paid to it for potential functional issues that might arise.
Precaution: Ensure that device tubing is not compressed or folded by the
application of cosmetic finishing.
Ensure the tube is NOT:
• Folded (Figure 3).
• Pressed up against sharp objects.
• Punctured.
• Dangling during gait.
• Located laterally, as there is more likelihood of damage.
TROUBLESHOOTING
Check the following:
• Is there leakage in the socket?
• Is the tube punctured?
• Is the membrane punctured or torn?
• Has the membrane been pulled out of the membrane housing?
• Is there dust or grit inside the device?
• Is the tube fully inserted on the inlet port? (Check both at the device
