the needle in the skin for this length of time and only withdraw from the skin
once the countdown is complete. In this way, you can guarantee that the set
insulin dose has been injected completely. Then, for five seconds, the display
indicates the dose administered and then goes out.
Note:
The ESYSTA
®
BT Pen is equipped with a mechanism that guarantees that the
insulin emerges evenly during the injection procedure. However, pushing the
dosing button too fast may lead to the insulin being injected too quickly. This
may lead to an alteration in the cells (hardening or lumps in the fatty tissue,
also called lipodystrophy or lipohypertrophy). Please press slowly until the
dosing button locks into place.
You should also systematically change your injection sites.
The dosing button is equipped with a strong spring to guarantee complete and
correct administration of the insulin. If the dosing button is not pressed in far
enough, this may lead to the dosing button not locking into place during the
injection, and popping back out again.
In this case, you must leave the needle in the skin and press the dosing button
in again – without twisting it – until it locks completely into place. Even if this
happens several times or the ESYSTA
®
BT Pen displays "3 Er" (see Chapter
10), only the previously set dose of insulin will be injected in total. The injection
process is only completed correctly once the dosing button locks and you have
held the needle in the skin for at least 8 seconds.
