Corpsman Up Vitals Monitor

Level: Intermediate
Skills Required: Soldering, Programming
Hours to Complete: 8

The Corpsman Up unit is a small, rugged device that provides real-time outputs of vital functions, in this case heart rate, when assessing a casualty. Multiple patients’ vitals can be monitored by simply switching to their channel using the rotary encoder and observing the output on the OLED monitor.  The Base is designed around the Parallax Propeller microcontroller and is equipped with a uOLED information display, an A/D converter and three corresponding LEDs that indicate battery life of the unit. The module only uses 13 of the Propeller microcontroller’s 32 I/O pins, which makes the incorporation of additional sensors, feedback devices and alarm indicators easy and achievable.  The base uses an XBee wireless module to receive the data from the remote nodes, and an Incremental Rotary Encoder for selecting different Remote node’s data to display.  The whole package is powered off of a 5 AA power pack located under the control board, which should provide many hours of run-time before needing to be changed out.
