Checking For Leaks - Ottobock 3 R60 Vacuum Gebrauchsanweisung

A reduced vacuum indicates contamination. In case of contamination, the system has to be
flushed to clean it. This flushes the vacuum pump and valves. The flushing process can also help
if the system is plugged.
Required materials:
>
Vessel with 30 ml to 60 ml distilled water, one collecting vessel
Preparations required:
The prosthesis is not worn for this process
1) Pour the distilled water into the prosthetic socket.
2) Position the vessel under the outlet hose.
3) Flex and extend the prosthetic knee joint to pump the water through the system.
4) Continue performing these movements until the full volume of water has been pumped out of
the system.
5) Clean the interior surface of the socket.

8.1 Checking for leaks

Remove the hose between the vacuum connector of the prosthetic socket and the suction connector of the
prosthetic knee joint. Use the T-piece to connect the vacuum gauge to the vacuum connector and suction con­
nector. Cover the entire vacuum connector on the inside of the socket with a small piece of paper and airtight
tape (e.g. Coroplast). Flex and extend the prosthetic knee joint until a constant vacuum of at least 300 mbar is
reached. Check whether the vacuum level is maintained.
Problem: Proximal seal
Solution: Check the proximal seal; seal or replace as
necessary.
