2 Functional Description

2.1 Extracorporeal Circuit

The elements for maintaining and monitoring the extracorporeal circuit
of the multiFiltrate are as follows:

 Pumps

 Heaters

 Pressure transducer

 Air detector

 Venous clamp

 Non-opaque/opaque fluid detector

 Blood leak detector

 Heparin pump

Chapter 2: Functional Description

2.1.1 Pumps

Altogether, the multiFiltrate is provided with four pumps:

Pump Delivery rate

Blood pump 10  500 ml/min

Filtrate pump 10  180 ml/min

Substituate pump 10  170 ml/min

Dialysate pump 10  170 ml/min

The pumps are driven by direct-current geared motors. To control the
speed, these motors are each provided with a clock pulse generator,
which is directly connected to the motor shaft. The pump processors for
controlling the individual pumps (P.C.B. LP 123) are fitted on the motor
housing.

All pumps are supplied with 24 V. The nominal voltage of the blood
pump motor is 20 V. The nominal voltage of the other pumps, however,
is 24 V.

A Hall sensor in the pump housing and a permanent magnet in each
pump door monitor the state of the pump door.

The line inserting position of the pump rotors for inserting and removing
the pump segments is detected by a combination of a reed switch (in
the pump housing) and a permanent magnet (in the rotor).

The functional test covers a check of all pumps.

Fresenius Medical Care multiFiltrate TM 6/03.07 2-1

Chapter 2: Functional Description

2.1.2 Heaters

2.1.3 Pressure Transducer

To allow heating of replacement fluids, two heaters, which are activated
and monitored independently of each other, are installed in the
multiFiltrate.

The heater foil is applied to the outside of the heater rod and supplied
with approx. 28 V. The temperatures are controlled and monitored by
altogether four NTC sensors (two for the operating processor and two
for the safety processor). This is implemented on P.C.B. LP 122.

Both heaters are tested during the functional test.

Four pressures are measured at the multiFiltrate:

 Arterial pressure,

Measuring transducer (P.C.B. LP 343-1) between the patients
arterial access and the blood pump
Measuring range: 280  300 mmHg

 Pre-hemofilter pressure

Measuring transducer (P.C.B. LP 343-1) between the blood pump
and the filter inlet
Measuring range: 0  750 mmHg

 Venous pressure,

Measuring transducer (P.C.B. LP 450-3) between the filter outlet
and the patients venous access,
Measuring range: 80  500 mmHg.

 Filtrate pressure or dialysate pressure

Measuring transducer (P.C.B. LP 343-1) between the filter
connector and the filtrate pump
Measuring range: 300  300mmHg.

All pressure transducers are subjected to the functional tests.

2.1.4 Air Detector and Venous Clamp

The air detector (P.C.B. LP 450-3) serves for the detection of air in the
extracorporeal blood circuit and operates on the ultrasound principle .
Both the transmitter and the receiver are integrated in the drip chamber
holder. Once the level in the venous drip chamber has fallen below a
certain threshold, the venous clamp is closed. This function is executed
independently of the operating or safety processor. The additional
board AD 28 increases the transmitter voltage during Preparation to
ensure that the level of saline solution is reliably detected.

The air detector is subjected to the functional test.

2-2 Fresenius Medical Care multiFiltrate TM 6/03.07

2.1.5 Optical Detector (Non-Opaque/Opaque Fluid Detector)

The optical detector (P.C.B. LP 450-3) detects, according to the infrared
principle, whether saline solution or blood is present in the tubing
system.

The optical detector is subjected to the functional test.

2.1.6 Blood Leak Detector

The blood leak detector (P.C.B. LP 125) is provided for the detection of
a potential blood loss through the membrane. It is operated applying a
two-color measuring section. In the course of this, red and green light is
alternately transmitted to a reference receiver or, through the filtrate
line, to a measuring receiver.

Both the transmitter and the receiver are integrated in the line holder.

The blood leak detector is subjected to the functional test.

2.1.7 Heparin Pump

Chapter 2: Functional Description

2.2 Weighing Units

The heparin pump is used for continuous heparinization of the blood.

A syringe plunger is moved by means of a carriage bar. The carriage
bar is connected to a threaded spindle via a slide. A microprocessor­controlled stepper motor causes the spindle to rotate. Depending on the
activation, the piston will move up or down.

One Hall sensor each signals when the piston has reached its upper
and lower end of travel. The safety system of the pump comprises a
speed monitoring device (slotted disc with optical sensor) and a motor
current monitoring function. The syringe types are set via a coding
switch (HEX switch).

The weighing units are used for managing the fluid balance during
treatment.

The weighing cells are operated according to the strain gauge principle.
Signal conditioning, including analog-to-digital conversion, is achieved
per weighing cell on the P.C.B. LP 127. The actual weights are
produced by the operating processor.

Scale 1 and scale 2 each have a useful load of approx. 12 kg.

The scales are subjected to the functional test. To test the scales, a test
weight (ball) of defined value must be taken off each scale. Proper
functioning of the scales can be concluded from the correct difference
between the weights before and after lifting.

Chapter 2: Functional Description

2.3 Ci-Ca Module (Option)

The Ci-Ca module is intended for regional citrate anticoagulation in the
CVVHD treatment therapy.

Turning power on The Ci-Ca module requires a supply voltage of 24VDC. This voltage is

provided by the multiFiltrate system’s power supply unit via the
connector in the lower IV pole support of the IV pole located on the right
of the system.
After the multiFiltrate system was turned on by pressing the power
switch on its rear, the supply voltage of the module is connected. The
operating processor of the Ci-Ca module switches into the standby
mode.
If the multiFiltrate systems is then turned on via the I/O key on the front
of the system, the operating processor of the Ci-Ca module will perform
an internal processor test. This test is performed simultaneously to the
processor test of the multiFiltrate system.

The Ci-Ca module communicates with the multiFiltrate basic system via
a serial interface.

Processor test If a test is not passed successfully, the module will not establish

communications with the multiFiltrate system. It is not possible to
perform a treatment with citrate anticoagulation. The multiFiltrate
system recognizes this problem and displays a message which
proposes to use an alternative anticoagulation equipment (e.g. heparin
pump) and which has to be confirmed by the operator.

T1 test The Ci-Ca module performs its own T1 test, independent of the T1 test

of the multiFiltrate system. This test will be started automatically and
simultaneously to the multiFiltrate T1 test after the prompt whether the
starting conditions are met was confirmed with [OK].

This test cannot be skipped or deselected.

System errors If it is still possible, system errors in the Ci-Ca module are shown on the

multiFiltrate display with the indication that citrate anticoagulation is not
available.

2.4 Functional Test (T1 Test) and Error Messages

After it has been turned on the rear and the [I/O] key has been pressed,
the system automatically starts the processor test. After completion of
the processor test, the display test will be performed. In this test, the
numerical characters are represented for 2 seconds in all of the three
fonts used. After this test, the functional test (T1 test) is started
automatically. Depending on the configuration in the SETUP (SETUP
automatic), the test is running in the background or (SETUP detailed)
the test steps are represented separately on the display.

Chapter 2: Functional Description

2.4.1 Battery Test, Part 1

At the beginning of the T1 test, the system assumes the terminal voltage
and loads the battery with a defined resistance over the entire test.

2.4.2 Scales Test

In the first step, the temperature compensation and calibration factors
are tested. In the second step, the scales are tared. The linearity test
follows in step three. The 4 test weights are lifted, and the weight (44.3
g) is tested for a tolerance of ±0.5 g. The offset drift is tested in step four.
The test weights are lowered again; the system expects a weight of 0.0
g with a tolerance of ±0.5 g. The time out for each step (2 to 4) is 10 sec.
In the event of an error, messages are emitted. Here, the error
messages section only relates to scales I. The messages are identical
for scales II to IV.

2.4.3 Pump Test

In the first step, the stop-by-OP function is tested, i.e. the pumps must
stop running. In this step, the safety processor releases the pumps, and
the operating processor does not activate the pumps. In the second
step, all of the four pumps are activated with a rate of 100 ml/min. The
safety processor checks whether the pumps are running at the correct
rate and whether the reed contact (line inserting position) is actuated. In
the third step, the operating processor activates the pumps and the
safety processor disables the pump activation, i.e. the pumps may not
be running. In the event of an error, messages are emitted. Here, the
error messages section only relates to the blood pump. The messages
are identical for the other pumps, i.e. the filtrate, substituate and
dialysate pumps.
