Chapter 1—Overview

Modules

The modules accompanying the 2008K are located just below the control panel. Each
component contributes to the task of transmitting the blood from the patient, through the
dialyzer and back to the patient. Any machine can be set up for a pre-pump or post-pump
arterial chamber, or single-needle dialysis (requiring two blood pumps) by adding modules,
or rearranging their order.
The preferred arrangements, shown in Figures 14 and 15 on page 36, can help to simplify the
routing of the blood tubing and minimize the possibility of kinking the bloodline.
The Blood Pump
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.
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
fluid level in the arterial chamber. This
level of fluid in the chamber, and cannot be used to lower it. This is to avoid introducing air
into the blood flow.
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 2008K 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.
