Chapter 1
Overview
The 2008T hemodialysis machine is designed to perform hemodialysis in hospitals and
dialysis clinics. It can be used for patients suffering chronic or acute renal failure.

Function of the 2008T Hemodialysis Machine

The 2008T hemodialysis machine is designed to provide hemodialysis treatment by
controlling and monitoring both the dialysate and extracorporeal blood circuits.
In the extracorporeal blood circuit, the blood is continuously circulated from the patient
through a dialyzer, where toxins are filtered out through a semi-permeable membrane, before
being returned to the patient. During this process, the extracorporeal blood circuit is
monitored for venous and arterial blood pressures, and for the presence of air and blood. The
2008T hemodialysis machine can also administer heparin evenly throughout the treatment.
In the dialysate circuit, the dialysate concentrates are mixed with purified water, heated,
degassed, and delivered to the dialyzer. Balancing chambers ensure that the incoming flow
of the dialysate is volumetrically equal to the outgoing flow in order to control ultrafiltration
from the patient.

Organization of the 2008T Hemodialysis Machine

The 2008T hemodialysis machine is designed for functional efficiency. The back of the
machine houses the utility connections such as water source, drain, and electrical
connections. By mounting them to the back, the water lines and power cord remain out of the
way during treatment.
The front of the machine contains all of the controls the operator needs access to during
hemodialysis. It can be broken down into three main sections. The top section contains the
control panel and houses the computer that runs the treatment program. The middle section
contains the modules used for the safe transmission of the blood to and from the dialyzer.
Dialysate is the primary concern of the bottom section of the 2008T hemodialysis machine.
Here the concentrates used to make up the dialysate are mixed and pumped to the dialyzer.
The following pages contain front and rear views of the 2008T hemodialysis machine and a
brief description of the machine's features. You should familiarize yourself with the location
and purpose of these features.
