Introduction; Vacuum System Function - OHIO WILLOW WOOD LimbLogic VS Series Prosthetist's Manual

Overview

Introduction

The LimbLogic VS is a remote-controlled
vacuum suspension system. The Vacuum
Pump is mounted inline on a prosthesis
to allow for complete integration without
the annoyances of tubes into the socket.
LimbLogic VS operates quietly and
features "Set and Forget" monitoring,
which means that the system monitors
the level of vacuum in the socket to
maintain a secure and comfortable fit.

Vacuum System Function

0 in-Hg
The system monitors the vacuum level and draws more vacuum as
needed to maintain the level between a minimum value (the Lower Set
Point) and a maximum value (the Upper Set Point). The difference
between the Lower Set Point and the Upper Set Point is called the
Vacuum Control Range. The Upper Set Point cannot be set higher
than the User Maximum. The User Maximum cannot be set higher than
the System Maximum of 20 in-Hg.
The prosthetist may adjust the User Maximum as well as the width of the
Vacuum Control Range. Both the prosthetist and the patient may adjust
the Upper Set Point.
The optimum vacuum setting is different for each amputee. Keep
in mind that a higher vacuum level is not always better. Higher
vacuum levels require that the Vacuum Pump use more power and
will therefore discharge the battery faster.
