Description

The DeRoyal Esophageal Stethoscope with Temperature Sensor (81-040418) is a disposable internal monitoring device used during anesthesia and critical care procedures. This 18 French esophageal catheter enables continuous core body temperature monitoring while simultaneously transmitting clear heart and breath sounds for effective intraoperative assessment.

The device features a specially designed distal balloon/cuff that enhances acoustic transmission when positioned in the esophagus. An integrated 400-series thermistor ensures compatibility with standard patient monitoring systems, allowing clinicians to accurately track temperature and vital sounds throughout surgical procedures.
