Description
The BC 20 plus / BC 60 plus / BC 140 plus hemoconcentrators are used to remove excess fluid
from the blood in an extracorporeal circulation during and immediately after a cardiac surgery
procedure. Transmembrane pressure (TMP, the pressure difference between the inside and out-
side of the hollow fiber membrane) is the driving force for ultrafiltration.
Internally the blood flows through the hollow fibers. The pressure inside the hollow fiber is cre-
ated by a blood pump and is higher than that on the outside. To support this process, the hydro-
static pressure can be increased by hanging the filtrate bag lower than the outlet. A vacuum can
also be applied in order to increase the filtration performance. The ultrafiltration performance
(amount of filtrate per time unit) is primarily affected by the blood flow and the transmembrane
pressure and is controlled mainly by occlusion at the outlet tube and/or negative pressure in the
ultrafiltration line.
Hemoconcentrators are ready for use after they have been primed and de-aired as the membrane
contains no stabilizers (e.g., glycerine).
The selection of a suitable hemoconcentrator depends on the protocol used and the required fil-
tration speed.
The device may only be operated by trained medical staff experienced in extracorporeal circula-
tion.
The device is intended to be used in a clinical environment.
Within the specified flow rate, the device can be used for all patients irrespective of age, body
weight and gender.

Intended Use
The BC 20 plus, BC 60 plus and BC 140 plus hemoconcentrators are used to remove plasma fluid
and the low-molecular substances dissolved in it from the blood or to concentrate highly diluted
blood solutions. They are intended for use in extracorporeal circulation during and immediately
after a cardiac surgery procedure.
The maximum duration of use is 6 hours.
The physician in charge of treatment has sole responsibility for decisions concerning use of the
hemoconcentrator.
