Abstract
An apparatus for monitoring a vascular access includes a dialysis circuit having a venous needle and a blood pump of a peristaltic type which generates oscillatory perturbations in the circuit. An optical sensor, arranged on a patient's body by the venous needle, perceives the perturbations transmitted through the needle and sends a pulsating signal to an analysis device. The absence of a pulsating signal indicates a detachment of the needle.
