Electronic oesophageal stethoscope, single-use

An electronic oesophageal stethoscope is a single-use medical device designed to be placed in a patient's oesophagus to listen to internal body sounds such as heart and lung activity, commonly during anaesthesia. It may also include integrated temperature sensing capabilities to monitor core body temperature via a thermistor or similar sensor, with electrical conductors linking the sensing elements to a proximal connector for attachment to standard monitoring equipment or earpieces.

As a single-use device, it is intended for one patient and one procedure only, then discarded to prevent cross-contamination. Regulatory oversight focuses on its design as a non-reusable, electronically enabled diagnostic tool, with supply and classification determined by its intended use as a temporary, invasive monitoring accessory under general medical device regulations.
