Fresenius Medical Care multiFiltrate IFU-EN-UK 15A-2015 12-15
pF = pressure from filter
P
ven
= venous pressure
P
pHF
= pre-filter pressure
Pre-filter pressure Measuring range: –50 mmHg to +750 mmHg
For haemoperfusion: –50 mmHg to +500 mmHg
Blood pump Delivery rate: 10 ml/min to 500 ml/min
(MPS: 10 ml/min to 300 ml/min)
(Citrate anticoagulation: 10 ml/min to 200 ml/min)
(Paed. treatment: 10 ml/min to 100 ml/min)
Control accuracy: ±5%
Inner line diameter: 6.4 mm
System accuracy of the delivered blood volume: ±10% over the
complete duration of the treatment for typical treatment situations.
Time-based standstill monitoring as a safety system against blood loss
through coagulation.
Operator stops the blood pump with the [STOP] key; immediate visual
alarm, acoustic alarm after 2 minutes.
Air detector Response threshold: drop of the fluid level, air bubbles, foam or
microfoam (blood / air mixture) over the entire blood flow range of
0 ml/min to 300 ml/min or 500 ml/min
Method: ultrasonic transmission
Heparin pump Pump type: syringe pump
Delivery rate: 0.1 ml/h to 25 ml/h
Resolution: 0.1 ml/h
Accuracy: ±5% for a delivery rate of 1 ml/h to 25 ml/h and a
measurement time of 2 hours up to a counterpressure of 1.2 bars
(calibrated for 30 ml Fresenius heparin syringes). With delivery rates
< 1.0 ml/h, the tolerance may exceed the specified ±5% accuracy.
Bolus administration: 0.5 ml to 5 ml in increments of 0.1 ml (the
maximum bolus amount to be injected is preset to 5 ml. This parameter
can be set to smaller volumes in the System parameters screen).
Ci-Ca drop counter Measuring range: 0 to 5 drops / second
Citrate pump * Pump type: roller pump
Delivery accuracy: pressure-dependent, ±10% (above typical pressure
range); for delivery rates < 6 ml/h, the deviation can be ±20%
Delivery rate: 10 to 600 ml/h (citrate / blood ratio: citrate concentration
per litre of delivered blood: 2–6 mmol/l)
Warning
Reduced treatment effectiveness
If the arterial pressure before the blood pump reaches extreme negative
values, the blood flow may be reduced, which will affect the
effectiveness of the treatment.
