摘要： 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.

摘要： A heart lung machine (HLM) with simplified setup based on role-profile mapping. The HLM includes a control assembly including a control display device and a processing unit configured to create a mapping profile by associating each of a plurality of HLM component names with one of a plurality of HLM component roles and assigning at least one dependency between a first one of the plurality of HLM components and a second one of the HLM components. Each of the plurality of HLM component roles is associated with an HLM component function.

摘要： A system for regulating blood flow in extracorporeal circulation, and including a blood reservoir to receive blood from a patient, an oxygenator to condition the blood, a centrifugal pump to pump the blood from the blood reservoir to the oxygenator and back to the patient, an electronic remote clamp to regulate flow of the blood, and a controller to operate in a flow control mode and a speed control mode. The controller includes an operational element to set a blood flow value in the flow control mode and to set a speed of the centrifugal pump in the speed control mode. The controller to automatically switch between the flow control mode and the speed control mode in response to one or more trigger conditions and to automatically switch between the speed control mode and the flow control mode in response to opening the electronic remote clamp.

摘要： Methods and systems for controlling one or more pumps of a heart-lung-machine. An illustrative method may comprise receiving an actual flow rate of a pump, determining the actual flow rate is from a primary pump, determining an available amount of the actual flow rate of the primary pump that is available to one or more subordinate pumps, comparing the available amount of the actual flow rate of the primary pump to a sum of set flow rates of the one or more subordinate pumps, and operating the one or more subordinate pumps in a proactive control mode or a reactive control mode.

摘要： A heart lung machine (HLM) includes a control area net-work (CAN); a pump; a number of sensors; and a control assembly, all communicatively coupled to the CAN. The control assembly includes a control display device and a processing unit, which is configured to fa-cilitate a semi-automatic safety check. To do so, the processing unit is configured to provide an HLM system safety check user interface (UI) on a display device, the HLM system safety check UI including a rep-resentation of each sensor; activate a sensor; present, via the UI, an in-dication of the activation of the sensor; determine an alarm state of the sensor; present a representation of the alarm state of the sensor on the control display device; present a safety check result of the sensor via the UI; and save a safety check result corresponding to the sensor.
