Abstract
A heart lung machine (HLM) includes: a pump actuator; an actuator control unit (ACU) operably connected to the pump actuator; a processing unit configured to receive a set of parameter data from the actuator; a display device configured to present a subset of the set of parameter data; and an input control device operably connected to the pump actuator. The input control device includes a rotatable knob. The ACU may be configured to: determine that the pump actuator has been stopped in response to a pump-stop trigger event; determine that the rotatable knob has been rotated to a first position; and in response to determining that the rotatable knob has been rotated to the first position, starting the pump actuator.

A heart lung machine (HLM) comprising:
- a plurality of actuators;
- a plurality of sensors;
- a peripheral processing unit configured to receive a first set of parameter data from the plurality of actuators, and a second set of parameter data from the plurality of sensors;
- a peripheral display device communicatively coupled to the peripheral processing unit;
- a plurality of actuator control units (ACUs), each of the plurality of ACUs operably connected to one of the plurality of actuators;
- and
- a control assembly comprising a control display device and a plurality of input control knobs, wherein each of the input control knobs is operably connected to one of the plurality of actuators;
- wherein the peripheral display device is separate from the control assembly;
- wherein each ACU is configured to:
- determine that its associated actuator has been stopped in response to a stop trigger event;
- and
- thereafter, determine that its associated input control knob has been rotated to a first position after the actuator has been stopped and then restart the actuator upon determining that the rotatable knob has been rotated to the first position.
