Ability dynamics RUSH FOOT EVAQ8 series Instructions For Use

SAFETY
This product is only to be used in lower limb prosthetic devices.

This system is intended to produce elevated vacuum

suspension for lower limb amputees already fit with an
appropriate vacuum suspension socket. The socket should
have a good fit with no voids. This is to help prevent
blisters and to prevent tissue from being drawn into the
voids or poor fit areas.
This product should only be fit by trained prosthetic

professionals.
The vacuum pump heel, socket valve, and associated

barbs & tubing should be inspected often for signs
of damage or excessive wear.
Ensure that the tubing is properly secured at all times.

FUNCTION
The RUSH FOOT EVAQ8 is a product designed to provide
the user with an elevated vacuum suspension for a lower
limb prosthesis. The vacuum pump compresses and expands
throughout the gait cycle. The cycling of the vacuum pump
pulls air from the socket, and after multiple steps, the system
can achieve vacuum levels of 18 to 22 inHg. The number of
steps needed to achieve maximum vacuum levels depends on
the free air in the system. This is determined by the fit of the
socket, number of socks used, and length of tubing required.

INSTRUCTIONS FOR USE
ASSEMBLY AND INSTALLATION
The RUSH FOOT EVAQ8 system comes preassembled
inside the heel of the RUSH Foot
system to the socket:
1. Connect a short piece of the tubing (4) to the socket
right angle barb (6).
2. Install the inline filter (5) into the distal end of the tubing
(the inline filter may be placed anywhere in the tubing
run between the socket and vacuum pump heel).
3. Connect a second piece of tubing (4) to the distal end
of the inline filter (5) and route the tube to the medial
side of the pylon or wrap the tubing around the pylon
(to prevent damage to the tube or snagging while walking).
4. Cut the tubing (4) to desired length and connect to the
straight barb (2) located in the recessed area of the vacuum
pump heel (1).
5. Secure the tubing to the pylon using the included hook
and loop tape (7) or other appropriate tape.
TROUBLESHOOTING
If vacuum cannot be generated or maintained by the system,
complete the following troubleshooting guide:
Inspect tubing (4) for cracks, holes or other potential leaks.

Reseat tubing at each connection point to ensure good seal.

Inspect inline filter. Remove the inline filter (5) from the tubing

and hold up to a light to look through it. If light can be seen
through it, the filter is clean. If the light is blocked, blast
air from a syringe through the inline filter (5) from distal to
proximal end (reverse of normal flow) to attempt to clear the
blockage. If blockage persists, the filter needs to be replaced.
Inspect socket right angle valve (6) and installation area for leaks.

Inspect socket expulsion valve (if used) and installation area

for leaks.
Inspect socket and suspension sleeve for potential leaks.
