초록 ▼

An ultrasonic air and blood foam detector for use in medical procedures involving extracorporeal handling of blood. A sensor assembly is adapted for positioning about a blood drip chamber and contains ultrasonic transducer means. The blood tube downstream from the drip chamber is preferably placed through the controllable clamp. Electronic circuitry provides excitation to the ultrasonic transducer means and signals transmitted through the chamber are received, amplified and processed by a level detector which provides an output signal for actuating the clamp when a predetermined low signal level occurs, indicating excessive air or foam in the drip chamber. In the preferred embodiment, a clip-on sensor assembly having epoxy lenses is provided.
