1.1 Construction and Function
The 4R220* Dynamic Vacuum System is a system for providing an active
vacuum. It consists of a component with an integrated piston pump, a liner
and a sealing sleeve.
The Dynamic Vacuum System uses the pistoning movements between the
residual limb and prosthetic socket to generate the vacuum. The piston of
the pump is equipped with magnets. A metallic counter-piece is installed on
the liner. Air is suctioned out of the space between the liner and prosthetic
socket into the cylinder during the swing phase, and this air is pressed out
during the stance phase. The result is a permanent vacuum, with a level that
adapts to the user's activity level.

1.2 Combination possibilities

This prosthetic component is part of the Ottobock modular system and can
be combined with other products of this modular system.
