The MEDTRONIC HC150A Emergency Handcrank serves as a critical backup component for Medtronic’s Bio-Console 560 Speed Controller System and related cardiopulmonary bypass setups. Designed for emergency scenarios where electrical power fails, this manual handcrank enables immediate operation of the centrifugal blood pump motor (like the 560A model), ensuring continuous blood flow during cardiac surgery without interruption. Its compact, ergonomic design allows quick attachment to the console for reliable mechanical override.
