CAUTION
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.
CAUTION
Risk of injury as a result of excessive strain.
Excessive impact loading typical with competitive sports beyond running or jumping activities,
may weaken the spring elements.
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 as a result of improper use. The patient should be properly instructed in the use
of the Harmony® Pump and Harmony® System.
NOTICE
Function loss as a result of dirty valves. Proper maintenance and care require periodic flushing
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
• Handle the Harmony® Pump carefully and examine regularly for any signs of damage and wear.
• Work with your prosthetist to make sure you understand how the Harmony® System feels
when functioning properly, when loss of vacuum occurs and what the overall effects of app-
lying an elevated vacuum to the limb are.
2.4 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 Otto Bock after completion of a corresponding training course.
