FEATURES
OF
THE
CS5+
The CS5+ improves upon the design and performance of its predecessors. The
CS5+ processes shed blood faster without compromising the quality of the end
product (concentrated RBCs). Haemonetics has improved and streamlined the
features and functions of earlier units and introduced the latest microprocessor
and sensor technologies to produce a significant advance in autologous blood
recovery systems, one which meets the demands and needs of the modern
operating room.
Automated
Operation
The bowl optics sensor in the centrifuge well, an ultrasonic air detector on the
tubing line and an optical effluent line sensor provide information to the CS5+
microprocessor. The processor determines the optimal processing parameters for
each individual cycles of the machine.
These parameters have been thoroughly tested and carefully calculated to
produce consistently optimal results under most operating conditions. Although
it is possible to reprogram the parameters, changes should be carefully
considered.
The
ultrasonic air detector
monitors the fluid flow in the tubing. When air in the
pump tubing is detected, the pump is stopped, the appropriate tubing is clamped
and a message is sent to the display.
The
bowl optics sensor
monitors the red blood cell level in the bowl. This sensor
initiates tripping to the WASH mode when the RBC level reaches the sensor trip
point.
Note: Bowl optics sensor is disabled when processing the 70mL bowl.
The
effluent line sensor
monitors the quality of the effluent as it leaves the bowl.
Among the actions the system might initiate are determining when the RBCs are
adequately washed or slowing the pump rate in WASH or FILL mode if RBC
spillage is detected. Additionally, with the 70mL bowl algorithm, the effluent line
sensor monitors the red blood cell level to initiate tripping to WASH mode.
An onboard computer
(microprocessor) uses
data from a variety of
sensors to control the
processing of blood,
allowing an
unprecedented level
of automation.
