Pneumatic systems
The Ikus has 3 pneumatic systems operating independently of each other. One
pneumatic system is required for each blood pump, while the 3
rd serves as an
emergency backup. Each pneumatic system includes:
• a compressor
• pressure and suction limiters
• pressure and vacuum cylinders
• control electronic
• control valves
The compressor, the pressure and the suction limiters deliver constant pressure
conditions in the pressure and vacuum cylinders. The control valves at the outlet of
each cylinder allow optimal adjustment of the positive and negative (suction) pressure
values.
Control computer
The Ikus system has 2 control computers operating independently of each other: the
active (main) control computer and the backup control computer.
Laptop with monitor program
Messages and pressure graphs in the monitor program inform the user of the current
status and working condition of the system. In addition, the laptop computer is used
