OHIO WILLOW WOOD LimbLogic VS Series User manual

1
This document provides instruction for the prosthetist in
the installation and use of the system. A separate document,
LimbLogic VS Patient Information, is included with each
system and should be provided to the patient upon delivery
of a prosthesis containing the LimbLogic VS.
The Vacuum Pump and fob included in this package are
electronically keyed together and can be used only with
each other.
LimbLogic VS - 1600 Series is now waterproof.

This pump is only designed to move air; use of Vaseline®
or similar lubricating creams inside the socket will clog the
pump. Do not allow foreign substances to be pulled through
the Vacuum Pump. This may impair function of your vacuum
system.
Do not allow acetone to contact the Vacuum Pump or fob.
The LimbLogic VS is not intended to be used as the only
means of attachment of prosthesis to patient.
All LLVS components have passed safety testing for use as
medical devices. Radio enabled devices transmit with a power
of less that one milliwatt and comply with United States and
international guidelines for low power transceivers. If LLVS
components will be used around safety critical devices such
as pacemakers or defibrillators, consult the manufacturer
for appropriate usage instructions. Consult the section on
Regulatory Information for more information on safety and
compliance.

Keys to Successful Use
1. Fabricate a non-porous Total Surface Weight Bearing socket
using a LimbLogic VS 4-Hole Attachment Plate. This is critical to
the proper operation of the system. Be sure to follow the fabrication
instructions provided with the 4-Hole Attachment Plate.
Prior to delivering the prosthesis, you may want to use the Diagnostic
Kit (LLV-1300) to confirm that there are no leaks in the system.
2. Fully charge the Vacuum Pump. (Refer to “Charging the Vacuum
Pump Battery” on page 9.)
3. Properly secure the fully charged Vacuum Pump to the socket,
Vacuum Plate (LLV-01043), or Vacuum Pyramid (LLV-01044) with
M6 flathead screws. Tighten the screws to 9 ft-lbs (12 Nm).
4. Assemble the prosthesis, inserting one end of the exhaust port tubing
into the exhaust port. Attach the other end of the tubing as desired.
5. Have the patient don an Alpha®Liner, the prosthesis, and an Alpha
Sleeve. For the best seal proximally, t he patient should fold over the
top edge of the liner and roll the sleeve up onto the folded edge
to create a gel-to-gel seal, as shown in the figures on pages 6 and 7.

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
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.

Charging the Vacuum Pump Battery
1. Remove the cap from the charging port on the Vacuum Pump.
2. Insert the charging plug into the charging port as follows:
a) Gently insert the plug into the port, holding the black plastic
portion of the plug, with just enough force to feel the plug touch
the port.
b) Align the green alignment marks on the charging port and the
charging plug.
The charging plug can only be inserted into the Vacuum
Pump charging port in one orientation. Forcing the plug will
damage the plug, will possibly damage the vacuum system,
and will void the warranty.
3. Plug the charger into a power outlet. The blue light on the two-pronged
adapter will light, followed by the green LED. The fob will display the
battery charging indicator.
If the green LED does not light, press and hold the reset button until
the light comes on.
4. When charging is complete, the green LED will flash. Disconnect
the power cord from the Vacuum Pump and from the power outlet.

5. Reinstall the cap onto the charging port on the Vacuum Pump.
Use ONLY an Ohio Willow Wood charger. For LLV-01042
series Vacuum Pumps use Ohio Willow Wood charger part
number LLV-01011. For LLV-01040 series Vacuum Pumps
use Ohio Willow Wood charger part number LLV-01010.
Use of any other charger may result in damage to the
Vacuum Pump or the charger or both.
If the charger needs to be reset, press the reset button. With normal
usage, the rechargeable battery should last for the life of the product.
Charging the Vacuum Pump Battery in a Vehicle
To use a vehicle’s power to charge the Vacuum Pump, you must purchase
a Power Inverter rated at 75 Watts or less to convert the vehicle’s 12V DC
power to 120V AC. Examples of acceptable Power Inverters include the
Digital Concepts 75 Watt Portable Power Inverter (available from general
retailers) and the Radio Shack® 75 Watt Power Inverter (Catalog
Number 22-153).
1. Plug the Power Inverter into the vehicle’s cigarette lighter socket.
2. Connect the charger to the Vacuum Pump.
3. Plug the charger’s two-pronged adapter into the Power Inverter’s
three-pronged receptacle.
