Ottobock 1C51 Taleo Vertical Shock Instructions D'utilisation page 24

Required materials: 30 ml to 60 ml distilled water, vessel
>
1) Fill distilled water into the prosthetic socket.
Alternatively, a residual limb sock can be soaked with distilled water to flush the vacuum
pump while walking.
2) Position the vessel under the outlet of the vacuum pump.
3) Alternately load and unload the prosthesis to pump all the water through the vacuum system.
4) Clean and dry the interior surface of the prosthetic socket.
7 Maintenance
CAUTION
Failure to follow the maintenance instructions
Risk of injuries due to changes in or loss of functionality and damage to the product
Observe the following maintenance instructions.
►
► A visual inspection and functional test of the prosthetic components should be performed
after the first 30 days of use.
► Inspect the entire prosthesis for wear during normal consultations.
► Conduct annual safety inspections.
► Check the condition of the functional ring as part of each inspection. If the user frequently
compresses the functional ring to the stop while walking, or if the functional ring exhibits vis­
ible damage, replace the functional ring (see page 25).
7.1 Troubleshooting leaks (Harmony only)
This section gives a methodical troubleshooting procedure for when the vacuum system leaks.
Checking area 1
First check the donning process and the sealing sleeve. No pressure gauge is needed. The vacu­
um suctions the sealing sleeve against the socket brim. The socket brim is clearly visible under
the sealing sleeve during the stance phase. If no vacuum is generated or the vacuum decreases,
this can be identified on the sealing sleeve.
• Ask the user to put on the prosthesis. Check the process to exclude errors during donning.
• Get the user to walk in order to build up a vacuum. Get the user to stand and check whether
the vacuum is maintained.
If the vacuum is not maintained: Replace the sealing sleeve with a new one.
•
• Get the user to walk in order to build up a vacuum. Get the user to stand and check whether
the vacuum is maintained.
If the vacuum is still not maintained: The fault is in area 2 or 3.
•
Checking area 3
• Connect the pressure gauge directly to the vacuum pump.
Activate the vacuum pump two to four times (vacuum of 340 hPa to 680 hPa).
•
If the vacuum is maintained: The vacuum pump is OK. The fault is in area 2.
•
If the vacuum is not maintained: Replace the valves of the vacuum pump. Then check
•
whether this measure was successful.

To check for leaks, the prosthesis is divided into areas.
Area 1: Prosthetic socket and sealing sleeve
•
Area 2: Socket connector and connection to the
•
vacuum pump
Area 3: Vacuum pump
