摘要： An ultrasonic detector (10), particularly useful in the level detection of blood within an arterial reservoir. The detector (10) includes a pair of opposed arms (16, 18) for connection to the arterial reservoir. One of the arms (16) carries a transmitting transducer (34, 36) while the other arm (18) carries a receiving transducer (38, 40) facing the transmitting transducer (34, 36). A clamping ring (32) is slidable on both arms (16, 18) for forcing the arms toward each other when the ring (32) is moved in one direction and for enabling the arms (16, 18) to move apart from each other when the ring (32) is moved in the opposite direction.
