Vacuum Assisted Suspension

A vacuum system provides superior fit between the liner and the socket while minimizing residual limb volume changes throughout the day.

This is achieved by using a pump and exhaust valve. The system is activated at each step when using a pump or a sensor. It regulates the required negative pressure within a defined range. The system controls the volume of the residual limb and simultaneously improves blood circulation. This type of system increases safety in everyday life.

Vacuum technology is intended to:

• Minimize limb movement in the socket
• Maintain a balanced volume in an amputee’s residual limb
• Facilitate perspiration evaporation within the socket
• Reduce friction between the limb, liner, and socket

An example of a Vacuum Assisted Socket System that SCOPe Orthotics and Prosthetics, Inc. uses is the Harmony Socket Enhancement System by Otto Bock.
