SONOCHECK® ABD Non-Invasive Medical Air Bubble Detectors The non-invasive SONOCHECK air bubble sensor series of ABD05, ABD07, and ABD08 have been designed for high safety requirements in medical devices. The compact and light-weight sensors detect air and gas bubbles in flexible plastic tubes filled with liquids such as blood, blood plasma, water or saline solution. Intelligent ultrasonic transmission technology and innovative safety concepts guarantee maximum sensor reliability for highest patient safety. The modular design of the sensor offers various possibilities for application-specific adaptations. → Non-invasive air bubble or full / empty detection → Compact sensor designed for dry coupling on flexible tubing → Application-specific microbubble detection → Dynamic compensation to changing acoustic conditions ensuring reliable bubble detection → High safety standards for maximum patient safety → Built-in electronics, no external electronic board required → Customization and miniaturization of sensor Technical Safety Features → Advanced fail-safe architecture → Cyclical self-tests ensuring functionality of all essential components → Watchdog to detect malfunctions → Initial test procedure after power on or software reset → Safe operation in electromagnetically sensitive environments Product Portfolio Medical Air Bubble Detectors

Input / Output Serial Interface Cyclical Self-Tests Fail-Safe Redundant Design Outer Tube Diameter Operating Temperature Ultrasonic Transmission Technology SONOCHECK ABD bubble sensors are based on intelligent ultrasonic transmission technology. Existing air bubbles and obstructions are detected by means of dynamic amplitude monitoring. When an air bubble passes the sensor channel, the signal level of the transmitted sound wave drops. The higher the drop of the signal level, the larger the size of the air bubble. Hw Amplitude monitoring for bubble detection As an extracorporeal circuit, the dialysis...
