    摘要: 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.

    摘要: The invention relates to a method for determining at least one flow parameter of a fluid (31) flowing through an implanted vascular support system (10), comprising the following steps: a) estimating the flow velocity of the fluid (31), b) carrying out a pulsed Doppler measurement using an ultrasound sensor (18) of the support system (10) in an observation window (201) inside the support system (10), wherein the observation window (201) is displaced at an observation window velocity which is determined using the flow velocity estimated in Step a), c) determining the at least one flow parameter of the fluid using at least one measurement result of the pulsed Doppler measurement or a measurement result of the pulsed Doppler measurement and the observation window velocity.
