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.
Claims20
A heart lung machine (HLM), comprising:
- 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 comprising a rotatable knob, wherein the ACU is 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 method of operating a heart lung machine (HLM), the HLM comprising 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 parameter data, and an input control device operably connected to the pump actuator, the input control device comprising a rotatable knob, the method comprising:
- detecting an occurrence of a pump-stop trigger event;
- stopping operation of the pump actuator;
- determining that the rotatable knob has been rotated to a first position;
- and
- starting the pump actuator in response to determining that the rotatable knob has been rotated to the first position.
A blood pump system for use with a heart lung machine (HLM), comprising:
- a pump actuator;
- an actuator control unit (ACU) operably connected to the pump actuator;
- and
- an input control device operably connected to the pump actuator, the input control device comprising a rotatable knob, wherein the ACU is 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.
