Harmony® System

Otto Bock’s Harmony® Vacuum Management System provides superb fit between the residual limb and socket while minimizing residual limb volume changes throughout the day.

The Harmony® system effectively reduces the amount of air between the socket and the liner. This is achieved through the use of a pump and an exhaust valve. The system, which is activated at every step when using the mechanical pump or by a sensor with the electronic version, regulates the required negative pressure within a defined range.

A damping and torsion function is also integrated into the mechanical pump. The Harmony® system controls the volume of the residual limb and simultaneously improves blood circulation. High adhesion improves proprioception. The prosthesis wearer feels what is happening under his or her prosthetic foot. This increases safety in everyday life. The Harmony® system is used in conjunction with a polyurethane liner. A standard or custom liner is used depending on the residual limb. The negative pressure system is sealed on the outside by means of a gel-coated sealing sleeve.

Certification is required to fit the Harmony® system. Please contact your national Otto Bock subsidiary for more information.
