Replacing Valves (Harmony Only) - Ottobock 1C51 Taleo Vertical Shock Instrucciones De Uso

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.
If this measure was not successful: Replace the functional ring. Then check whether this
•
measure was successful.
If this measure was not successful: Send the vacuum pump to the manufacturer for
•
inspection.
Checking area 2
• Connect the pressure gauge with a T-piece between the socket connector and the vacuum
pump.
• Seal the opening to the socket connector on the inside of the prosthetic socket with air-tight
adhesive tape (e.g. PVC tape).
Activate the vacuum pump until a vacuum of 340 hPa to 680 hPa is reached.
•
If the vacuum is not maintained: The socket connector is defective. Replace the socket
•
connector. Then check whether this measure was successful.
If the vacuum is maintained: The glued joint of the socket connector is likely defective.
•
• Seal the opening to the socket connector on the inside of the prosthetic socket with a small
piece of paper and air-tight adhesive tape (e.g. PVC tape).
Activate the vacuum pump until a vacuum of 340 hPa to 680 hPa is reached.
•
If the vacuum is not maintained: Glue the socket connector again. Then check whether this
•
measure was successful.

7.2 Replacing valves (Harmony only)

1) Pull the old valves off the functional ring.
To check for leaks, the prosthesis is divided into areas.
