1.0 i-digits™ quantum
1.1 Product Description
design. dexterity. intelligent motion.
Based on the industry-leading design of our i-limb™ product
range, i-digits™ quantum combines unsurpassed functionality
with style. i-digits™ quantum incorporates gesture control via
the patented and ground-breaking i-mo™ technology and is
the first partial hand prosthesis that can change grips with a
simple gesture.
Key features include:
• Smarter
- gesture control powered by i-mo™ technology uses
simple gestures to change grips
- proximity control made available via grip chips™
technology
• Faster
- adjustable speed boost increases speed up to 30%
• Stronger
- up to 30% more power when needed
- improved component design for easier and more reliable fabrication
- 50% longer battery life
• Smaller
- new form fitting design decreases device size in
every dimension
- smaller digits now available
We are pleased that you and your clinical team decided that
i-digits™ quantum is the most appropriate prosthesis for your
needs. You will have discussed your functional goals with your
clinical team. This manual, along with the training and support of your clinical team, should help you understand how
i-digits™ quantum will help you accomplish these goals.
i-digits™ quantum is a fully customized partial hand prosthesis
with individually powered fingers. i-digits™ quantum fingers
move independently and bend at the joint to work in conjunction with any remaining fingers to help significantly increase
functional 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 using your i-digits™ quantum 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™ quantum is covered under the Touch Care program. Please contact your clinician for details about your specific Touch Care coverage.
1.2 Intended Use
i-digits™ quantum is intended to be used by individuals with
partial hand loss or deficiency. Devices are suited to individualswith 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.

1.3 Prosthesis overview
Each i-digits™ quantum 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 recommend that you make a note of it on page 16 of this manual.
i-digits™ quantum will not provide you with sensation and so
you will not be able to feel things such as heat and moisture. idigits™ quantum 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™ quantum. 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™ quantum is like any other electrical device so do not
immerse 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™ quantum without an approved cover.

1.4 Prosthesis Overview: Control Strategies
i-digits™ quantum can access automated grips using a range
of control options.
gesture control:
By enabling i-mo™ technology, gesture control allows an au-
tomated 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
app control:
i-digits™ quantum can access a grip at the touch of an icon on
the my i-limb™ app, enabling all automated grips to be avail-
able. These are called quick grips™.
i-digits™ quantum will exit automated grip when icon is tapped
again, or by selecting another grip icon.
Speed boost is also available on the app using a simple slider
bar. 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™ quantum to activate an automated grip. There
are 4 potential triggers: hold open, double impulse, triple impulse and co-contraction.
proximity control:
Grip chips™ are small Bluetooth chips which can change the
grip programming of i-digits™ quantum when you position it
near to the chip. The grip chips™ can be positioned around
the user’s environment in practical locations to allow access
to the optimum grip for particular daily tasks. Individual grip
chips™can be programmed using the biosim™ or my i-limb™
app.
