Ottobock 1C62 Triton Harmony Gebrauchsanweisung Seite 23

To avoid the risk of accident and possible injury to the patient, the foot must no longer be used
after a noticeable loss of function has occurred.
This noticeable function loss may be the result of reduced spring effect or forefoot resistance,
in some cases accompanied with abnormal noises.
Measure: Have the prosthetic foot examined and, if necessary, replaced at a specialist workshop.
NOTICE
Function loss due to mechanical damage. If the Functional Ring shows any signs of damage,
proper operation of the device cannot be ensured (impossible to create an elevated vacuum).
The Functional Ring is to be protected against mechanical damage. The Functional Ring must
be replaced by qualified personnel if it shows any signs of damage (see Sections 4.4 and 4.8).
NOTICE
Health risk as a result of using wrong prosthetic socket. The application of wrong socket
techniques can cause health risks for the patient (increased accumulation of fluid in the resi-
dual limb, e.g. oedemas). The prosthetic socket has to be fabricated following exclusively the
Harmony socket fabrication technique.
NOTICE
Function loss as a result of dirty valves. Proper maintenance and care require periodic flus-
hing 30-60 ml (1-2 fl-oz) of distilled water with about 5 to 10 pumps/steps through the Harmony
System in order to clean the valves. If flushing does not solve the issue the plastic valves (4Z106
straight & 4Z108 elbow) can be easily replaced (see figure 7).
INFORMATION
Damage due to incorrect environmental conditions.
Prosthetic components must not be exposed to the following elements:
• corrosive elements (such as fresh water, salt water, and acids)
• abrasive substances (e. g. sand)
The footshell material is not UV- or water-resistant.
Do not grind the surface of this prosthetic foot, as this can lead to premature wear.
Using this medical product under such conditions will render all claims against Otto Bock
HealthCare null and void.
2.6 Qualification of the prosthetist
The fitting of a patient with a Harmony System may only be carried out by prosthetists who have
been authorized by Ottobock after completion of a corresponding training course.
