The Blood Pump Module - Fresenius Medical Care 2008T Operator's Manual

The Blood Pump Module

The blood pump draws blood from the patient and pumps it to the dialyzer and back to the
patient in a closed circuit. To accomplish this, the pump segment of the blood tubing is
threaded through the pump housing along a circular track. As the pump rotor rotates, twin
rollers squeeze the pump segment, pulling and pushing the blood through the blood pump
segment. The speed of the pump can be adjusted using the arrow keys on the blood pump or
the Blood Pump Rate button on the "Home" screen (see page 75 for more information). The
blood pump can be stopped by pressing the Start/Stop key or by opening the blood pump
door. When the door is open, the diameter of the pump segment is shown in the display
window.
Pressing the single  key on the Blood Pump Module activates a small pump that raises the
fluid level in the arterial chamber. This  key (level adjust) can be used only to raise the
level of blood in the chamber, and cannot be used to lower it. This is to avoid introducing air
into the blood flow.
Warning! The  key (level adjust) on the Blood Pump module can only be used to raise
the level in the arterial chamber. Do not press the level adjust key so long that the pressure
transducer protector becomes wet. Wet transducer protectors must be replaced to avoid
erroneous pressure readings.
Note: A separate hand crank is supplied with the pump at the back of the machine that can
be used to return the blood to the patient in case of a power failure.
Note: The 2008T hemodialysis machine's modules and internal hydraulics involve fluids:
accidental spills can occur. Spills may cause slips and falls and can cause damage to
carpeting and other surfaces. To contain such spills, the machine should be on a spill-
tolerant surface. Clean up spills immediately.
