Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A device for pumping blood in an extracorporeal circuit includes a centrifugal pump that suctions the blood to be pumped via a venous hose line connected to a suction side of the pump and releases it via an arterial hose line connected to a release side of the pump. The device includes a flow sensor that detects a released quantity on the release side of the pump and emits a measurement signal corresponding to the released quantity, a pressure sensor that detects the pressure on the release side of the pump and emits a measurement signal corresponding to the pressure, and an evaluation unit to which the measurement signals of the sensors are fed and which determines a value corresponding to the pressure on the suction side of the pump, taking into consideration the two measurements signals and the rotational speed of the centrifugal pump.

Abstract: A display and control device for medical equipment, comprising several identically configured display/control units, which are located on a base unit. The base unit is equipped with a bus, to which the display/control units and components of the medical equipment are connected. The base unit comprises connection devices, which are used to connect the display/control units to the bus. Once a display/control unit has been connected, a configuration unit transmits configuration data to the display/control unit and only then defines which function the display/control unit is to fulfill. This permits defective display/control units to be simply replaced. The construction of the display/control units is likewise simple and not susceptible to malfunctions.
