An electronic interface facilitates automatically transferring data from a heart pump controller database to an EMR system, thereby reducing or eliminating the need for caregivers to manually transcribe heart pump operational data from a heart pump controller screen to the EMR system. Some embodiments reduce or eliminate the need to periodically visit a patient to record the operational data. Instead, once programmed, the interface can automatically periodically send the operational data to the EMR system.

A system including tubing and a filter configured to be fluidly coupled to a vacuum source and to a heater/cooler unit by the tubing. The filter includes a filter container having negative air pressure in the filter container provided by the vacuum source to pull aerosol from the heater/cooler unit into the filter container and eliminate and/or reduce the aerosol emitted from the heater/cooler unit.

A system for calculating cardiac output (CO) of a patient undergoing veno-arterial extracorporeal oxygenation includes measuring first oxygenated blood flow rate by a pump in the extracorporeal blood oxygenation circuit as introduced into an arterial portion of the patient circulation system and a corresponding arterial oxygen saturation, then changing the pump flow rate, such as decreasing, to produce a corresponding change in arterial oxygen saturation (wherein such change is outside of normal operating variances, operating errors or drift), which change in the arterial oxygen saturation is measured. From the first flow rate and the second flow rate along with the corresponding measured arterial oxygen saturation, the CO of the patient can be calculated, without reliance upon a measure of venous oxygen saturation. Alternatively, the CO of the patient can be calculated, without reliance upon a change in flow rate by changing a gas exchange with the blood in the extracorporeal blood oxygenation circuit to impart corresponding changes in a blood parameter in the arterial portion of the patient circulation system and the blood delivered from the extracorporeal blood oxygenation circuit.

A system for carbon dioxide (CO2) removal from a circulatory system of a patient includes a medical device providing extracorporeal lung assist (ECLA) treatment to the patient through extracorporeal removal of CO2 from the patient's blood; at least one control unit controlling the operation of the medical device so as to control a degree of CO2 removal obtained by the ECLA treatment; and a bioelectric sensor detecting a bioelectric signal indicative of the patient's efforts to breathe. The at least one control unit is configured to control the operation of the medical device based on the detected bioelectric signal.

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.

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 perfusion system includes a fluid reservoir configured to hold a portion of fluid, the portion of fluid having a volume, the fluid reservoir having a total capacity that is greater than the volume; an imaging device, the imaging device configured to obtain image data corresponding to the fluid reservoir; and a controller. The controller is configured to receive the image data from the imaging device; determine the volume based on the image data; and facilitate control, in response to at least one of a user input and the determined volume of the portion of fluid, of an operating parameter corresponding to the fluid reservoir to facilitate changing or maintaining the volume of the portion of the fluid.

Provided is an extracorporeal circulator capable of judging a timing suitable for detachment with high accuracy. The extracorporeal circulator includes a blood removal side catheter with a part that can be inserted into a patient and guide the blood taken from the patient; a pump that can take the blood from the patient and return the blood to the patient; a blood transfer side catheter provided downstream of the pump, and that has a part that can be inserted into the patient and guide the blood sent out from the pump back into the patient; a pump rotation speed detection unit that can detect a rotation speed of the pump; and a control system including at least one of an extracorporeal circulation management system that can judge stability of the extracorporeal circulation and a cardiac function measurement system that can judge stability of a heart function of the patient.

A percutaneous catheter for blood removal includes a catheter tube extending in an axial direction with a plurality of distal side holes provided on a distal end part of the catheter tube and communicating a lumen of the catheter with an outside of the catheter tube. The plurality of distal side holes is spirally arranged in the axial direction of the catheter tube, and at least one distal side hole at the proximal end side of the spirally arranged side holes is formed to have a diameter smaller than a diameter of a distal side hole at the distal end side of the spirally arranged side holes.
