1.2 Intended Use
i-digits™ is intended to be used by individuals with partial
hand loss or deficiency. Devices are suited to individuals
with any 3, 4 or 5 digit loss, while patients or users with 1
or 2 digit loss are also indicated when the digits of loss are
either the thumb or the main digits of opposition, namely
the index and middle fingers.
* Note: only available on i-digits™ quantum.
i-digits™ is a fully customized partial hand prosthesis with
individually powered fingers. i-digits™ fingers move inde-
pendently and bend at the joint to work in conjunction with
any remaining fingers to help significantly increase func-
tional capabilities.
Each digit of the device has its own motor that allows the
digits to run until they meet the object being grasped. The
result of this is the device taking the shape of that object
(compliant grip). The power for the prosthesis comes from
two batteries which are located in the wristband. Initially,
you and your clinical team will develop control of opening
and closing your hand. At this stage, you should be able
to carry out a wide range of functional daily activities us-
ing your i-digits™ device.It takes time and practice to gain
control and master the best way to perform tasks with your
prosthetic device. The pace at which individuals gain this
control varies.
Your i-digits™ is covered under the Touch Care program.
Please contact your clinician for details about your specific
Touch Care coverage.

Fig. 1: Serial Number
Fig. 2: Weight distribution
1.3 Prosthesis overview
Each i-digits™ has a unique identifying number called the
serial number as depicted on the image to the right (fig.1).
This is an important piece of information and we recom-
mend that you make a note of it on page 16 of this manual.
i-digits™ will not provide you with sensation and so you
will not be able to feel things such as heat and moisture.
i-digits™ cannot absorb any shock as your own body is able
to do. If high degrees of force are applied, you may cause
damage to your i-digits™. If this does happen, then please
contact your clinical team who will contact Touch Bionics
Customer Support team to resolve the matter as quickly as
possible. To best protect the hand when carrying objects,
the weight should be distributed evenly across the digits
as close to the knuckles and palm of the device as possible
rather than out on the tips of the digits. The image to the
right (fig.2) is an example of how to correctly carry objects.
i-digits™ is like any other electrical device so do not im-
merse in water and do not pour water over the device.
When cleaning the covering use a damp cloth to remove
any dirt.
Do not use i-digits™ without an approved
cover.
If you have any specific questions about your i-digits™
device then please contact your clinical team or visit the
Touch Bionics website www.touchbionics.com for the latest
information and news.
Avoid the use of oils on your skin, such as
Vaseline or oil based moisturisers.

1.4 Prosthesis Overview: Control Options
i-digits™ can access automated grips using a range of control
options depending on the type of i-digits™ device being used.
gesture control (only available on i-digits™ quantum):
By enabling i-mo™ technology, gesture control allows an auto-
mated grip to be accessed through a smooth and natural motion
of the prosthesis in 1 of 4 directions.
To access gesture control:
• Device must be in full open hand mode
• Hold arm parallel to ground (elbow bent to 90°)
• Maintain an open signal until finger twitches
• Move the hand (within 1 second) in direction assigned to
desired grip
• i-digits™ quantum will adopt the grip
Note: gesture control can also be accessed using co-contraction.
Depending on how your clinician has set up your prosthesis for
you.
app control:
i-digits™ can access a grip at the touch of an icon on the my i-
limb™ app, enabling all automated grips to be available. These
are called quick grips™.
i-digits™ will exit automated grip when icon is tapped again, or by
selecting another grip icon.
Speed boost (not available on i-digits™ access) is adjusted using
a simple slider bar on the my i-limb™ app. This increased speed
can provide benefits of a more responsive action, more natural
appearance of motion and increased grip force.
muscle control:
Triggers are specific muscle signals that you can use to instruct
i-digits™ to activate an automated grip. There are 4 potential trig-
gers: hold open, double impulse, triple impulse and co-contrac-
tion.
proximity control (not available on i-digits™ access):
Grip chips are small Bluetooth chips which change the function
of the i-limb quantum hand when the hand comes close to them.
Grip chips are programmed (and can be reprogrammed using
the myi-limb App.
To use grip chips, make sure the i-limb hand is not connected to
the App. The i-limb must be fully open/digits stalled open. Each
grip chips must be at least 24” apart.
Proximity is accessed by holding the i-limb hand fully opened
near (15 cm/ 6”) to a grip chip. Wait until the grip is accessed,
which may take up to 3 seconds. To exit a grip accessed via prox-
imity control, give a long open signal.
Double tapping a grip chip activates the grip. Quickly tap a grip
chip twice, just like double-clicking a computer mouse. The LED
on the grip chip flashes once when tapping is successful. NOTE:
a 3 second pause between each double tap is required.

2.1 Wristband componentry
The wristband houses the microprocessor and the batter-
ies unit. It is buckle fastened, designed to fit loosely around
the forearm. To switch the device on, press the button and
the LED light will illuminate. To switch it o, press the but-
ton again and the LED will light momentarily.
The wristband is designed to fit loosely around the forearm.
It is not designed to be used for suspension of the prosthe-
sis or to hold electrodes in position against the skin.
2.2 Controlling your prosthesis
To fit i-digits™ a socket interface has been specially cre-
ated by your prosthetist team. They will have made this to
ensure it is comfortable and fits directly to your residual
hand. You may experience some minor redness on your
residual hand but this should not last very long after you
remove the device. If the device is causing you discomfort
or aecting you using your i-digits™ then we recommend
that you contact your clinician.
As part of the fitting process, your prosthetist selected
the best method for you to provide control of your device.
This communicates to the processor whether you want
i-digits™ device to open or close. The most common input
type is called an electrode. Electrodes pick up on the elec-
trical activity that your body gives o when you contract
a muscle. While gaining good control may take time and
practice, your method of input should not cause pain. Talk
with your prosthetist if you do not understand how your
input control is working or if it is causing discomfort.

2.3 Battery Charging
i-digits™ is powered by two, 800mAh, 3.7 Volt batteries
which have been specifically designed to meet the power
requirements of i-digits™ devices. Four batteries are pro-
vided, two for the wristband and two spares. Two 3.7 V bat-
teries will be needed with the wristband (the wristband will
not work with only one battery).
Each battery is equipped with a LED display alerting you
when the battery is low on charge. If the battery is low on
charge the LED will illuminate RED. The LED will remain
illuminated until the battery is adequately charged.
Only use supplied Touch Bionics charger
to charge batteries. Depending on your
location, you will receive one of the chargers
shown (fig. 7).
If you intend to travel outside of your home country you will
need to ensure that you have a Touch Bionics charger that
will work in the country to which you are traveling. Addi-
tional chargers are available from Touch Bionics (see fig.7).
As an alternative to charging directly from domes-
tic power, a car charger is also provided with the
i-digits™.
