Active Vacuum System

AirFeed® Active Vacuum System

Active Vacuum eliminates the present disadvantages of socket systems and sucks the air between the socket and silicone sleeve and discharges it in the prostheses for below knee amputation patients.

By discharging the air inside the socket, the compatibility between the socket and the amputated part of the patient is ensured. By this means, the patient feels his/her prosthesis more lightly, the piston flow (entrance-exit) likely to occur in the socket is stopped, the patient is ensured to continue to his/her life for a long time actively, and the reaction force of the ground starting with stepping on the ground during walking of the patient is absorbed.

A connector rotating 360 degrees is used for modular connection of air suction line to the apparatus according to the invention in the socket application.
