1. Introduction
Your ESYSTA® BT Pen is a device for injecting insulin. As a component of
the tele-diabetological ESYSTA
®
product system, it automatically saves
all of the insulin quantities injected, along with the associated time.
This data is transferred in encrypted form via Bluetooth® radio technology1 to
your ESYSTA® App. The ESYSTA® App can be found in the corresponding App
portals. The transfer of data to the ESYSTA® Portal is also supported.
With the ESYSTA® BT Pen, you can use all common insulin cartridges from
various manufacturers. So you can continue to use the insulin preparation you
have previously been prescribed.

Thank you for trusting our ESYSTA® devices. As you will see, the ESYSTA®
BT Pen will make your treatment easier.

2. Correct use
2.1 ESYSTA® BT Pen
The ESYSTA® BT Pen is a medical product. For the treatment of
diabetes mellitus by trained patients or trained carers, it is used to manually
inject insulin preparations from 3 ml insulin cartridges2 (100 IU/ml). Up to 60
IUs can be injected through human strength. You can set your insulin dose in
whole units. An ESYSTA® BT Pen is only intended for treating one patient.
2.2 ESYSTA® Adapter (disposable adapter)
The ESYSTA® Adapter is an accessory (a consumable) required for operating
the ESYSTA® BT Pen, in order to be able to use insulins from dierent
manufacturers. There are three dierent designs.
The ESYSTA
®
Adapter is a disposable item. A new ESYSTA
®
Adapter
must be used with each new insulin cartridge. Information on selecting
the right ESYSTA® Adapters for your insulin preparation can be found in
Chapter 7.

Also referred to as a cartridge or ampoule.

2.3 Data transfer
The ESYSTA® BT Pen can transfer the injected quantities of insulin together
with the date and time of the injection to the ESYSTA® App via a conventional
smartphone using Bluetooth® radio technology.
You also have the option of registering with the ESYSTA® Portal at
www.esysta.com. On the Portal, you can allow your doctor to view your
treatment data. For optimal use of the system, we recommend that you agree
your treatment with your doctor or practice.
2.4 Information for doctors and medical sta

other insulin pens. There are additional functions and operating steps. If you
instruct patients in the use of the ESYSTA® BT Pen, or use it on patients, you
should be comprehensively familiarised in advance with both the operation
and these operating instructions in order to avoid making errors in use. Should
you have any questions, please contact us (see p. 56).

3. Information on safe use
Before using the ESYSTA® BT Pen, you must always receive training
from your doctor, pharmacist or diabetes adviser.
Before using your ESYSTA® BT Pen, please read all of these operating
instructions carefully and follow the instructions exactly. Not following
the instructions may lead to injecting a dose of insulin that is too high or too
low.
If you need help, please contact your doctor, pharmacist, diabetes
adviser or Emperra GmbH.
Before each use, check your ESYSTA® BT Pen for damage. In the case
of damage such as cracks or breaks, or if the display or parts of the
display are not functioning, do not use the ESYSTA® BT Pen.
Always handle your ESYSTA® BT Pen with care. Strong vibrations
may damage the device. The ESYSTA® BT Pen must not be used
improperly or opened using force, as this will damage the device and the
guarantee will be rendered invalid.

Always set the number of units correctly. The dose is increased by exactly
one unit for each click when the dosing button is turned clockwise. The
dose is increased by exactly one unit for each click when the dosing button is
turned anti-clockwise. Do not use the ESYSTA® BT Pen if the units displayed dier
from the number of units identied through the clicking and locking mechanism.
In this case, contact Emperra GmbH, your doctor, pharmacist or diabetes
adviser.

of other foreign matter. Only transport and store your ESYSTA® BT Pen
with the cap on, and keep it in a safe place where it cannot be confused with
other things.
On the ESYSTA® Adapter is a scale intended for use in estimating the
amount of insulin remaining in the cartridge. This scale must not be
used for measuring the dose of insulin.
Keep your ESYSTA® BT Pen, your insulin cartridges and injection
needles out of reach of unauthorised persons - and children in particular.
There are magnets in your ESYSTA® BT Pen. If you have a heart
pacemaker, please consult your cardiologist to have conrmed in writing

3.1 Risks associated with use
Find out about the risks and side eects of your insulin preparation.
In spite of all of the safety precautions, there are residual risks from the use of
the ESYSTA® BT Pen.
lInfections may occur if the injection needles are used more than once.
lUnprotected injection needles can cause injuries and transmit
diseases. Third parties - particularly children - can be injured or
even killed by the needles and the insulin contained within them.
.
lToo much or too little insulin can be injected through incorrect operation.
Under-dosing through too little insulin being injected will lead to
hyperglycaemia (high blood sugar), which may nally render the patient
unconscious and is often associated with complications. Over-dosing by
injecting too much insulin causes hypoglycaemia (low blood sugar), which
can quickly become a critical condition.
lIn order to prevent incorrect doses, the ESYSTA® BT Pen must be suciently
vented before each use and particularly after each change of cartridge; see
also Chapters 6.7 and 6.8.
