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.

Regulating blood flow in extracorporeal circulation

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.

A device for establishing venous inflow to a blood reservoir of an extracorporeal blood circulation system includes a restricting unit for restricting a venous inflow line and a vacuum unit for supplying vacuum to the blood reservoir. The device includes a control unit that, upon setting the desired venous flow rate, automatically supplies a first actuating signal to the restricting unit for restricting venous inflow to the blood reservoir and supplies a second actuating signal to the vacuum unit for establishing a degree of vacuum within the blood reservoir, so as to achieve the set venous flow rate. The device includes a venous flow sensor.

Embodiments of the subject matter include a heart lung machine (HLM), including a plurality of actuators and a peripheral processing unit configured to receive a set of parameter data from the plurality of actuators. The HLM also may include a peripheral display device configured to present a subset of the set of parameter data and a control assembly comprising a control display device configured to present a user interface having a representation of a parameter value and an associated indication, where at least a portion of the associated indication overlaps at least a portion of the representation of the parameter value.
