Ottobock’s Harmony® Vacuum Management System provides superb fit between the liner and socket while minimizing residual limb volume changes throughout the day.
The Otto Bock Harmony vacuum offers a secure suspension by creating a negative vacuum in the socket, offering unprecedented comfort, control and safety. The system uses a pump and an exhaust valve, which are activated at every step when using the mechanical pump or by a sensor with the electronic version. The pump and valve allow the system to constantly regulate pressure for the optimal suspension. The mechanical version of the Harmony also offers a shock damping and torsion function, integrated into the mechanical pump.
In combination with the other Harmony System components (e.g. an Anatomic 3D PUR Liner, a ProFlex Sleeve and the custom made Harmony compatible socket) the Harmony E2 provides volume management for the residual limb, enhanced suspension and reduced forces in the socket.
