Patent ID: 11458237

Abstract:
A blood purification apparatus that detects dislodgement of a puncture needle is provided. The apparatus includes an arterial electrode, a venous electrode, a power source capable of causing a current to flow through an arterial puncture needle and a venous puncture needle that are stuck in a patient, a body-surface electrode closely attached to a body surface of the patient, a detection device capable of acquiring a heart rate of the patient in accordance with an electrical signal detected by the body-surface electrode, a monitoring device capable of monitoring in real time the current flowing through the arterial electrode or the venous electrode and a change in an impedance in a body of the patient that is detected by the detection device, and an identifying device capable of identifying a dislodged state where the arterial puncture needle or the venous puncture needle is dislodged from the patient, in accordance with the change in the impedance that is an object of monitoring by the monitoring device.
