Abstract
A device for detecting embolus uses ultrasonic signals reflected on a fluid flow in a body. The device features a first ultrasonic unit for receiving a first signal generated in a first position in a vessel and a second ultrasonic unit for additional reception of a second signal generated in a second position in the body. The device also features a detector unit for detecting the embolus. The detector unit is triggered only if the time interval between the characteristic changes in the first and second signal, corresponding to a possible embolus, exceeds a minimum value, or if the characteristic signal change occurs in one of the signals only.
