Caution
When inserting the tubing systems, the following precautions
must be respected:
– The tubing systems have to be free of kinks, tension and twists and
must not be jammed (risk of hemolysis). Use the line holders
provided.
– Ensure the correct position of the screwed connections, especially
of the connection sites to the patient, the dialyzer and the system
and check or correct them during the treatment if necessary. Take
the appropriate measures if required (e.g. retightening of the Luer
Lock connection or replacement of the tubing system).
– Check the protective caps for tight fit and tighten them if necessary.
– The lines for the supply of infusions should always be clamped,
except if they are needed.
– During long-term operation, the blood lines must be changed after
24 hours at the latest.
– Do not use cannulas with a diameter of > 20 gauge to pierce the
septum of the injection sites. Insert the cannula vertically and in the
center of the septum. Disinfect the injection sites with 70% alcohol
before use.
– The blood pump must be set to the diameter of the pump segment,
refer also to the product label of the blood lines. If a wrong line
diameter is set, this may cause significant deviations in the blood
flow and thus in the dialysis dose.
– Materials which come directly or indirectly into contact with blood
are: Plasticized PVC, unplasticized PVC, polyethylene,
polycarbonate, latex-free rubber, ABS.
– The minimum temperature of the tubing systems during use is 18 °C.
Caution
Delivery operation of the pump(s) with open doors
(blood pump, substituate pump, optional Single-Needle pump):
When the doors are open and the rotor of the pump(s) is running, make
sure that
no objects , such as fingers, hair or ball point pens, come into
contact with the rotor (risk of injury).
Arterial pressure measurement unit:
Prevent foreign objects from coming into contact with the arterial
pressure measurement unit.
Heparin pump:
If heparin syringes of third party suppliers are used, the operator is
responsible and has to ensure that the syringe data displayed match the
actual data.
Heparin syringes without Luer lock are not recommended as the
connection between the heparin syringe and the blood lines may come
loose. If heparin syringes without Luer lock are used it is the operator’s
responsibility to ensure that the connection between the heparin syringe
and the blood lines does not loosen inadvertently.
IV pole:
Securely fix bags or other objects to be hung from the IV pole.
