3.0 Description
The Otto Bock Harmony Pump combines the function of a vacuum pump and the function of a damping shock
absorber in one unit. The 4R144 and 4R150 include the additional features of axial rotation and torsional shock
absorption.
Function of the Vacuum Pump
The Harmony Pump is designed to generate an elevated vacuum to increase the linkage between user and
prosthesis, and requires a sealed environment between the user's leg/liner, the socket, and the sealing sleeve.
Once the environment is sealed, the Harmony Pump, which is compressed and released during normal walking,
draws air from the socket through one-way valves and evacuates it through the pump. After multiple cycles of
compression an elevated vacuum of 15-25 in. Hg. (508-847 millibars) is created in the sealed socket environment.
The Harmony Elevated Vacuum Socket System:
• Improves fluid exchange in the residual limb and helps to control daily volume fluctuations
• Increases proprioception
• Increases suspension to improve gait and overall function
• Reduces forces to the residual limb and liner
• Reduces moisture buildup on the residual limb
Function of the Shock Absorber
The Harmony shock absorption functions helps to reduce vertical and torsional forces in the extremities during
walking. The result is an improvement for both the function and loading situation of the prosthesis wearer.
