EXPLOREEchelon<sup>VAC</sup>

EchelonVAC

Suitable for outdoor use
Niveau d’activité 3

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.

Caractéristiques

  • Biomimetic Hydraulic Technology with integrated elevated vacuum
  • Walking motion generates a natural vacuum
  • No power required, quiet gentle operation
  • Lightweight, compact design
  • Low build height
  • E-carbon springs for efficient energy return
  • Split toe design for ground compliance on uneven terrain
  • Sandal Toe Foot Shell

How does EchelonVAC work?

With every step, the wearer presses their weight into the prosthesis, initially expelling air through a one-way valve. Simultaneously the ankle plantarflexes, 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 dorsiflexes.

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.

EchelonVAC - How it works

Innovative Design

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.

The Evidence

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:

  • Reduce volume fluctuation
  • Reduce interface pressures
  • Improve wound healing
  • Reduce pistoning
  • Improve gait symmetry, balance and reduce risk of falls
  • Greater comfort and improved overall satisfaction
