bibag Details
The bibag connector is a hardware option that allows the usage of a dry
bicarbonate powder to generate dialysate solution for the 2008®T and the
2008K@HOME™ hemodialysis machines. The bibag is a bag filled with dry
bicarbonate powder with special inlet and outlet ports. Underneath the bibag
door, the bibag hangs on two nozzles, which allow for the entry of purified
water and the exit of bicarbonate concentrate solution. A door handle locks
the bibag door in place over the bibag.

Warning: The concentrate displayed on the screen must match the labels on the
acid container. Make certain there is enough concentrate in the containers to
complete the treatment.
Warning: The specific concentrate, sodium, and bicarbonate settings must be
prescribed by a physician.
Warning: Acid and basic bicarbonate hemodialysis concentrate must be diluted
(mixed with purified water as specified in the AAMI standards for water for
dialysis) immediately prior to application only.
Warning: Use aseptic technique.
Warning: Always verify the conductivity and approximate pH of the dialysate
solution through independent means before initiating dialysis. Verify that the pH
is normal and that the conductivity is reasonably close to the theoretical value. If it
is not, do not initiate dialysis.
Warning: Replace a leaking bibag immediately. Spills can cause damage to
carpeting and other surfaces. To contain such spills, the machine should be on a
spill-tolerant surface. Spills can cause slips and falls; clean up spills immediately.
Caution: Only the bags manufactured by Fresenius Medical Care may be used in
the bibag connector.
Note: When the bibag connector is installed, the online pressure holding test
becomes mandatory. For more information, see the Online Pressure Holding Test
section of the 2008®T Hemodialysis Machine Operator’s Manual P/N 490122 or
the 2008K@HOME™ Hemodialysis Machine Operator’s Manual P/N 490180.

Hydraulic Component Descriptions
100 – bibag Fill Valve
The bibag fill valve opens as needed to add water to the bibag during dialysis. When the
bibag is not used for bicarbonate during dialysis, this valve will remain closed. In rinse
and cleaning modes, this valve will alternate with valve 103.
101 – bibag Vent Valve
The bibag vent valve opens momentarily during bibag dialysis when air is detected in the
bibag air separation chamber. When the bibag is not used for bicarbonate during dialysis
(jug mode), this valve will open momentarily when air is detected in the bibag air
separation chamber.
103 – Hydrochamber Outlet Valve
The hydrochamber outlet valve opens in dialysis when valve 100 is closed. In rinse and
cleaning modes, this valve will alternate with valve 100.
104 – Bicarbonate Port Valve
Closed for bibag dialysis. Opens to empty the bibag and during bibag startup. Opens
when sodium bicarbonate concentrate is supplied. When sodium bicarbonate is supplied
by a pressurized supply, this valve will open and close based on pressure at pressure
transducer 110.
105 – Acid Port Valve
Used to regulate the pressure to the acid pump. Will open and closed based upon
pressure at pressure transducer 106.
106 – Acid Port Pressure Transducer
Senses pressure of the acid concentrate supply. Pressure detected from this sensor is used
in conjunction with valve 105 to regulate the pressure to the acid concentrate pump.
108 – Rinse Port Valve
This valve is electrically in parallel with valve 104. It opens and closes at the same time
as valve 104.
110 - bibag Pressure Transducer
The bibag pressure transducer is used to measure the pressure inside the bibag. Also used to
measure the pressure of the sodium bicarbonate concentrate source when bibag is not used.

Hydraulic Component Descriptions (cont.)
111 – bibag Air Separation Chamber
The bibag air separation chamber separates air from the sodium bicarbonate concentrate
upon leaving the bibag. It also is used to separate air from the sodium bicarbonate
concentrate supplied by external sources (pre-mixed concentrates).
112 – bibag Air Separation Chamber Air Sensor
The bibag air separation chamber air sensor detects air in the air separation chamber.
113 – bibag Conductivity Cell
The bibag conductivity cell is used to measure the conductivity of the sodium bicarbonate
concentrate leaving the bibag and the conductivity of the pre-mixed concentrates.
114 – bibag Temperature Thermistor
The bibag temperature thermistor is used to measure the temperature of the bicarbonate
concentrate leaving the bibag and the pre-mixed concentrate.
115 – bibag Present Switch
The bibag present switch is built into the bibag connector. The switch is positioned so
that when a bibag is attached to the bibag connector the switch is pressed indicating the
presence of a bibag bag.
116 – Bicarbonate Temperature Thermister
Used with conductivity cell 117 to measure conductivity.
117 – Bicarbonate Conductivity Cell
Measures conductivity of the bicarbonate concentrate from the bibag after it is mixed
with R.O. water.

Door
The bibag connector holds the bag with dry bicarbonate during dialysis. The bibag
connector incorporates a three position door (see Figure 3). The door may be placed in
the position open, operating, or bypass. In the open position (1) and (4), a bibag may be
installed or removed from the connector. The operating position (5) is used when a bibag
is installed for dialysis. The bypass position (3) is the completely closed position (not
possible if a bag is hanging from the connector). The door must be in the closed position
(3) for rinse, cleaning, and jug dialysis mode. Position (2) should not be used.

Hydraulic Operation
Dialysis with bibag
Heated water from chamber E of the hydrochamber flows to the junction of valves 100 and
103. Valve 100 opens and the bibag will start filling when the dialysate temperature at
temperature sensor 3 reaches 30 degrees C. Valve 100 will close when the pressure
reaches 150mmHg as monitored by the pressure transducer 110. After this initial fill,
valves 104 and 108 open, valve 103 closes, the balancing chamber valves open and any
excess gas generated in the bag is flushed through the hydraulics down the drain. The flow
pump runs and the machine is kept in bypass during this initial flush. Afterwards,
additional water will be added to the bag to maintain pressure in the bag of about 90mmHg.
The conductivity cell (113) and temperature sensor (114) measure the conductivity and
temperature of the sodium bicarbonate concentrate as it leaves the bag. The temperature
compensated conductivity determines the concentration of the sodium bicarbonate
concentrate and the delivery rate of the bicarbonate pump (17).
If air is sensed by the probes (112) in the air separation chamber, valve 101 is
momentarily opened to vent the air.
If the bibag pressure does not change while the bicarbonate pump is pumping, an airlock
condition is detected. To remove the airlocked condition in the bicarbonate pump, valve
100 opens to pressurize the bag to 150mmHg. Next, the flow is stopped, the balance
chamber valves are opened up, the flow pump runs, and the machine is kept in bypass.
Conductivity cell 117 checks the amount of sodium bicarbonate added to the dialysate
and an error will be displayed if the solution is not within ±5% of expected.
Dialysis with Sodium Bicarbonate Concentrates
Jug bicarbonate dialysis is also supported with the bibag hydraulics. To run in this mode,
the bibag connector door must be completely closed and the bicarbonate connector pulled
out. Valves 104 and 108 will open and close based on pressure transducer 110 to allow
bicarbonate concentrate to reach the bicarbonate pump. Conductivity and temperature of
the solution is monitored.
Rinse & Mandatory Rinse
Mandatory rinse is run after a chemical disinfect. Both rinse and mandatory rinse are the
same valve sequence for the valves in the bibag hydraulics. Valves 104 and 108 alternate
opening every 3 seconds. Valves 100 and 103 alternate opening every 3 seconds. Valve
101 is also opened periodically when conductivity is low. Valve 105 is open.

Acid Clean
The bibag valve sequence is the same as chemical rinse. Both concentrate and
bicarbonate connectors are plugged into acid.
Heat disinfect
The bibag valve sequence is the same as rinse.
Flow off
Valves 100 and 101 closed. Valve 103 open
bibag Empty
The bibag empty procedure removes the liquid solution from the bag to make disposal of
the used bag easier and cleaner. To empty the bag, valves 100, 103 and 105 are closed
while the balancing chamber and valves 104 and 108 are opened up. The flow pump runs
to suck solution from the bag and send it out the drain. During the emptying process, the
hydraulics are kept in bypass. When the empty is complete, the operator is notified,
normal balance chamber switching resumes, but the hydraulics remain in bypass until a
new bag is installed and correct conductivity of the dialysate returns.

Electronic Description
bibag Interface Board
The bibag interface board ‘piggybacks’ onto the actuator - test board and communicates
with it. The bibag hydraulic assembly and the bibag distribution box 2 connect
electrically to the bibag interface board with ribbon cables.
The bibag interface board contains all of the electronics required to activate the 5
additional valves, read conductivity from the bibag and bicarbonate conductivity cells,
read temperature from the bibag and bicarbonate temperature thermistor, read the status
of the bibag air sensor, and read the status of the bibag door’s internal switches. A
microcontroller on the board controls all of these processes and communicates serially
with the actuator - test board. The presence of the communications between the bibag
interface board and the actuator - test board indicates to the system the presence of the
bibag hydraulic components.
The bibag pressure transducer is automatically calibrated when the door is open, and the
value is saved into memory on the bibag interface board.
bibag Hydraulic Assembly – Distribution Board
The bibag hydraulic assembly - distribution board is a passive board that connects to the
bibag interface board through a 26 pin cable. All of the individual bibag components on
the bibag hydraulic assembly connect electrically to this distribution board.
bibag Distribution Box 2 – Distribution Board
The bibag distribution box 2 - distribution board is a passive board that connects to the
bibag interface board through a 20 pin cable. All of the individual bibag components on
the distribution box 2 connect electrically to this distribution board.
