Maintenance - Otto Bock Dynion 3R85 Instructions For Use Manual

→ Dry the prosthetic knee joint with a lint-free cloth and allow it to air dry in order to remove
residual moisture.
→ Check the prosthetic knee joint for proper functioning (e.g. flexion and extension, switch­
ing threshold, cycling mode and lock).
→ After reaching the maximum period of use for salt water (days per year: 14 – hours per
day: 0.5), have the prosthetic knee joint checked by qualified personnel.
→ Deactivate cycling mode.

9 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.
►
► NOTICE! Do not lubricate and grease the prosthetic joint.
► NOTICE! Repair work must be performed exclusively by manufacturer service.
► Arrange regular maintenance intervals with the patient depending on the level of use.
► Following an individual period for the patient to get accustomed to the prosthesis, check the
settings of the prosthetic joint and adapt them to the patient's requirements again as needed.
► The prosthetic components should be inspected after the first 30 days of use.
► Inspect the entire prosthesis for wear during normal consultations.
► Conduct annual safety inspections.
► As part of the safety inspections, inspect the prosthetic joint for wear and proper functionality.
Special attention must be paid to the movement resistance, switching threshold, bearing
points and development of unusual noises. Full flexion and extension must always be ensured.
Make adjustments as needed.
► After using the product in salt water, check it closely for salt residues and signs of corrosion
(e.g. set screws).
► Check all product functions to ensure they work reliably (especially the locking function, activ­
ated and deactivated cycling mode, flexion and extension, and the switching threshold).
► In case of functional limitations and damage, send the product to the manufacturer's service
department.

rather than the product.
► Instruct the patient to have the prosthesis inspected as soon as possible in case of visible cor­
rosion (e.g. rust on the set screws that clamp the proximal adapter on the prosthetic knee
joint).
► Check the sacrificial anode during the annual safety inspection.
► Remove any dirt and crystals from the area around the sacrificial anode prior to inspection.
→ Continue using the product if the sacrificial anode is present as shown in the illustration.
( Entire
dimension: < 5 mm)
→ NOTICE! If the sacrificial anode has been fully or partially destroyed down to the specified
dimension as shown in the illustration, have a new sacrificial anode installed by the
manufacturer's service department. ( Sacrificial anode no longer present;
sacrificial anode present – dimension: ≥ 5 mm)
10 Disposal
In some jurisdictions it is not permissible to dispose of the product with unsorted household
waste. Improper disposal can be harmful to health and the environment. Observe the information
