The PO Box is a dsPIC30F2012-based pulse oximeter that can be used by medical professionals and home healthcare providers to measure a critically ill patient’s arterial oxygen saturation. A small mezzanine board interfaces to a sensor and serial port. A 2 × 8 character display provides SPO2 and heartbeat data.

In my opinion a very original idea, because I’ve never seen a eletronic stethoscope. And besides the originality you’ve got functionality which is great. The stethoscope gets the sound trough a microphone place inside the classic stethoscope sensor. The temperature and pulse are showed on a 3 digit 7 segment display.
