SECTION 1  SYSTEM OVERVIEW
Federal Law restricts that the Espire Elbow system is to be purchased,
configured and fit only by a board-certified prosthetist, licensed by the
state in which they practice. This device is intended for use in accordance
with the information contained in this document. Instruct the patient on
proper use of this device before transferring device to patient.
Intended Use Statement:
The Espire Elbow is to be used exclusively for external prosthetic fittings
of the upper limbs. The Espire Elbow processes the end-user’s input
signals to activate and control powered elbow movement.
1.1 INTRODUCTION
Thank you for purchasing the Espire Elbow system from College Park
Industries. The following pages will cover everything you need to know
about this system from setup to operation. If you have any questions,
concerns or comments, please contact our Technical Service team at
800 728 7950 (US/Canada), ([phone] (International).
In the following document you will find information on everything from
fabrication to maintenance and care of the Espire Elbow system. Read
these instructions carefully and educate the end-user on all functions
of this product before final delivery. Espire is a tool designed to make
the lives of prosthetists and transhumeral (or above elbow) amputees
successful and productive.
The Espire Elbow is a state-of-the-art, internally powered, myoelectric
elbow prosthesis. Espire Pro uses electrical signals from muscles to
proportionally control a powered elbow and terminal devices, whereas
the Espire Hybrid uses electrical signals from muscles to control terminal
devices only. College Park does not recommend that the device contain
more than 3 degrees of freedom; the clinician should evaluate according
to the combination of terminal devices that are required by the patient.
The system’s versatility also allows many other control schemes such as
switches, linear transducers, pattern recognition systems, etc. Signals
from these inputs are processed by Espire’s internal microprocessor unit
and then sent to the respective devices.

3.3 CONNECTING CABLES
TO THE INPUT BOARD
When attaching cables, note the proper orientation. The connectors
are “keyed” or asymmetrical to assure proper alignment. The connector
should plug in easily and is held in place with friction.
When removing cables, pull close to the connector to avoid pulling on the
wires. Wires that become loose could cause intermittent operation.
3.4 STRAIN RELIEF DISC
The strain relief disc prevents accidental disconnection of the input
wires and acts as a seal to prevent moisture and dirt from entering from
entering the area with the receptacles.
1. Thread the input wires through
the center hole of the disc, then
connect the wires to the board.
Apply silicone grease to the plug
connectors before inserting into the
board (see section 3.3).
2. Fasten the wires to the strain relief
disc using the provided zip-tie. This
is necessary to prevent accidental
wire disconnection.
Sealing the Input Board
3. Apply a small amount of silicone
grease at the perimeter seal
between the disc and the ring.
4. Line up the fastener holes on the
disc to the mounting threads on the
input board, then gently press the
disc to the board.
5. Use (2) M2 x 5mm fasteners and
washers to secure the disc to the
input board. A 1.3 mm Allen wrench
has been provided to tighten the
fasteners finger-snug
(2 in-lb / 0.23 N-m).

A/C MYOELECTRODES WITH
TRUSIGNALTM TECHNOLOGY
4.1 ELECTRODE OVERVIEW
College Park’s A/C electrodes are an eective and convenient way to
increase signal resolution. These are the recommended electrode option,
designed to work exclusively with the Espire Elbow; however, cased DC
electrodes are also compatible.
TruSignal Technology
The electrodes utilize TruSignalTM technology; a unique process for
buering a signal immediately, sending it to the microprocessor, and then
amplifying it.
The benefit of amplifying the signal later in the process is that it results
in a cleaner and clearer signal than other electrode options. The result is
better slow speed control of the elbow and its accessories.
How it Works:
1. TruSignal board, located directly at the electrode, “cleans” signal and
lowers impedance.
2. Cleaned A/C signal delivered to Espire microprocessor.
3. Software in elbow amplifies the signal corresponding to the
patient’s calibration.
4.2 ELECTRODE KITS
An electrode kit consists of a wire harness with TruSignal boards attached,
and a set of metal electrodes. To order an electrode kit by part number,
identify the number of myo sites (1 site, 2 site, 4 site, 6 site), wire length
(6 in, 12 in, 24 in), and dome size (pediatric, medium, large).

Espire Elbow Technical Manual | 14
Example Part Number:
CP TLE 212 M - TruSignal AC Electrode Kit, 2 Site, 12 in, Medium Dome
Remote Metal Electrodes
The remote metal electrodes are Cavity-Backed™ for use with the
electrode kits and snap onto the TruSignal boards. They have a recess on
the back allowing the inner socket material to deform into this space,
thus reducing the bulge on the outer socket.
Dome selection is based on the patient’s needs. Medium electrodes
are most commonly used, however, if the patient has significant
soft tissue over the myoelectric sites, the large electrodes are
recommended. Pediatric electrodes are for pediatric applications.
Large Medium Pediatric
4.3 ELECTRODE PLACEMENT
Since the electrodes are independent, the clinician can place these
where they want in the socket. Each site has 2 active electrodes.
In general, each pair of electrodes should lie along the longitudinal
axis of the muscle with an edge-to-edge spacing of not more than 1
cm. An additional pair of reference electrodes (grounds) should be
located o-axis, away from the active electrodes where they will not
interfere with muscle signals.

4.5 ELECTRODE INSTALLATION INSTRUCTIONS
1. Use an awl or other small tool with a
sharp point to puncture the center of the
electrode location.
For test sockets and rigid inner sockets,
a power drill with 0.0938” drill bit is
recommended.
2. Insert the post of the electrode dome
through the inside of the socket. The dome
should be inside of the socket where it will
contact the residual limb.
3. Place the nut snap onto the post of the
electrode dome and hand tighten. Use
the provided hex driver (CP HXD) to
tighten snugly.
4. Use a pair of wire snips to trim the post.
The post should not protrude beyond the
snap when secured in place.
5. Snap the electrode boards onto the
electrode dome posts and ensure they
are attached securely. The location of
the electrodes can always be changed
later if desired.

AXIS ELECTRONIC LOCK ACTUATOR
5.1 ELECTRONIC LOCK ACTUATOR OVERVIEW
The Axis Shoulder Joint is available with an electronic lock actuator in
both exoskeletal and endoskeletal versions. The shoulder is powered
by the Espire Elbow battery and controlled via the input of choice. It
requires an output cable to actuate the lock, which connects to the
input board.
5.2 ROUTING CABLES THROUGH THE
SHOULDER JOINT
In the exoskeletal version, both input and output wires are routed through
a channel between the yoke plate and the humeral plate.
Input wires travel from the input control (electrodes, switches, etc) to the
input connector board. The Axis output wire travels from the shoulder
joint to the input connector board.
