Blatchford EchelonVT Guide De L'utilisateur page 2

The term device is used throughout this document to refer to EchelonVT.
This device is to be used exclusively as part of a lower limb prosthesis.
The device provides limited self-alignment of the prosthesis on varied terrain and following
footwear changes. It is intended to improve on postural sway and symmetry while easing
abnormal pressures at the socket interface.
The device also includes a spring element capable of absorbing axial and rotational shocks
intended to reduce sheer stresses at the residuum/socket interface.
After continuous use the ankle casing may become hot to the touch.
To minimise the risk of slipping and tripping, appropriate footwear that fits securely onto
the foot shell must be used at all times.
Be aware of finger trap hazard at all times.
Any changes in performance of this device must be reported to the practitioner.
Changes in performance may include:
• Increase in ankle stiffness
• Changes in axial or torsional stiffness
• Reduced ankle support (free movement)
• Softening of springs
• Excessive play in bearings
• Any unusual noise
The user should contact their practitioner if their condition changes.
The practitioner must also be informed of any changes in body weight and/or activity level.
A regular visual check of the foot is recommended. Signs of wear that may affect function should
be reported to the practitioner (e.g. significant wear or excessive discoloration from long term
exposure to UV).
Cleaning
Use a damp cloth and mild soap to clean outside surfaces. Do not use aggressive cleansers.
Maintenance
Maintenance must be carried out by competent personnel. It is recommended that maintenance
is carried out annually.
