What is it indicated for?

The SimulScope® Bedside Auscultation System allows the user to amplify heart, lung and bowel sounds and transmit them via infrared energy to wireless headphone worn by more then one listener. The system uses an electronic stethoscope connected to a transmitter unit and a receiving unit(s) for each listener.

Indications for use read by OCR from a scanned FDA summary, so letters may be misread. Check the PDF before quoting it.
