Optimal socket connection is critical to an amputee’s comfort, security and stability. By pairing Biomimetic Hydraulic Technology with an elevated vacuum system, the design of EchelonVAC works to create a secure and comfortable socket connection.
By harnessing natural ankle motion, EchelonVAC quietly creates elevated vacuum, helping to maintain an optimally fitting socket throughout the day.
With every step, the wearer presses their weight into the prosthesis, initially expelling air through a one-way valve. Simultaneously the ankle plantaflexes, actively drawing air out of the socket. This air is held in the vacuum chamber and expelled through a secondary one way valve as the tibia progresses and the ankle dorsflexes.
The result is greater residual limb volume control and an improved connection between the residual limb and the socket. For the user, this reduces relative movement, improving proprioception and control of the prosthesis for greater comfort and safety every day.
The innovative design of EchelonVAC is lightweight and has a low build height as no external power source is required.
With no batteries or pump to worry about, EchelonVAC is quiet and easy to fit.
When used in conjunction with a Silcare Breathe liner, the vacuum is applied directly to the residual limb to further enhance the connection between the limb and the socket.
Active vacuum systems help to stabilise residual limb volume to improve socket stability and proprioception. Scientific studies have shown that elevated vacuum systems help to:
