Vacuum & Suction Socket Designs & Components
Harmony (Vacuum Assist Suspension System)
The Harmony® System uses a pump and a one-way valve to effectively create vacuum between the socket and liner. With every step, the system is activated and maintains the required vacuum to control the volume of the residual limb while improving circulation. Shock absorbtion and torsion control add extra function. Better suspension improves proprioception, allowing the user to feel more connected to their environment and improving security in everyday life. The Harmony® System is used with either a standard or a custom polyurethane liner depending on the residual limb conditions.
