pen/syringe and insulin with you. Without insulin, diabetic ketoacidosis
may develop and this may require in-patient hospital treatment.
Caution: If an “Error E4: Occlusion” occurs, immediately check your
blood glucose level, because insulin delivery may have been interrupted. If
your blood glucose level is high, take appropriate actions according to your
health care team’s instructions.
Caution: After an error occurs, your insulin pump returns to STOP and the
insulin delivery is interrupted. In order to maintain insulin delivery, you
must act immediately according to the instructions given for each error
code and put your insulin pump into RUN to continue the insulin delivery.
An “Error E4: Occlusion”may be caused by a blocked infusion set, a blocked adapter
or by the cartridge itself (for example if the cartridge has been reused).
Please refer to section 7.2.4 “Error E4: Occlusion” for further information.
Caution: Properly tighten the infusion set to the adapter to avoid leakage.
Turn the infusion set luer-lock connector only as far as to the stop. Do not
turn it any further and do not use any auxiliary tools as this may crack the
infusion set luer-lock connector and result in leakage. Your insulin pump
cannot detect infusion set leakage. Therefore, you must inspect all
parts of the infusion set at least every three hours during the day and be-
fore you go to sleep. Should you detect any loss of insulin and all parts are
correctly tightened, immediately replace the leaking component. Immedi-
ately check your blood glucose level, because insulin delivery has been in-
terrupted. Check your blood glucose level and take appropriate actions ac-
cording to your doctor’s and/or your health care team’s instructions.
Caution: Air bubbles in the cartridge, adapter and in the infusion set
cause the infusion of air instead of insulin. Your body does not receive the
required amount of insulin. An “Error E4: Occlusion” may be delayed.
Remove these bubbles while filling the cartridge and/or priming the infu-
sion set. Make sure the infusion set is not connected to your body. Cold in-
sulin may release air when warmed. Use only insulin at room temperature
when filling the cartridge and priming the infusion set.
Warning: Any changes or modification to the devices not expressly ap-
proved by Disetronic Medical Systems AG could void your ability to ope-
rate the Accu-Chek D-TRONplus insulin pump.
1.2 Precautions
Caution: If your insulin pump automatically returns to RUN (timeout)
before you finish programming a bolus, no bolus is delivered. Check the
bolus history screens on your insulin pump for the bolus amount delivered
with time and date and program a new bolus if necessary. Please refer to
section 6.1.1 “Review the bolus history” for further information.
Caution: When your insulin pump is in STOP, it does not deliver any
insulin.
Caution: Be aware that the interruption of insulin delivery (e.g. due to a
leak, occlusion or loss of insulin potency) or the malfunction of your insulin
pump can result in a rapid rise of your blood glucose level. Although your
insulin pump has an internal security check system, it cannot alert you if
your infusion set is leaking or if the insulin you are using has lost its po-
tency.
Frequent testing of your blood glucose levels helps you to find your personal settings
more rapidly and to detect incorrect dosages early. Successful pump therapy requires
at least four blood glucose tests per day, or as directed by your health care team.
Caution: Since only short-acting or fast-acting insulin is used for insulin
pump therapy, there is only a small insulin reserve in the body. If insulin
administration is interrupted for any reason (e.g. technical problem of the
insulin pump, leakage in the cartridge, occlusion of the infusion set tube or
of the infusion set needle, infusion set needle has slipped out of the infu-
sion site), you must be prepared to replace the missing insulin immedia-
tely. Always carry spare accessories and disposables (adapter, infusion set,
insulin cartridge, PowerPack) as well as your backup pump or an insulin
