Summary of Digital blood pressure meter design using PIC microcontroller
This article describes a reference design for a non-invasive digital blood pressure meter using the PIC24FJ128GC010 microcontroller and MCP6N11 instrumentation amplifier. The device utilizes oscillometric detection to measure systolic and diastolic pressures while applying the Measurement While Inflating (MWI) principle to reduce discomfort by shortening measurement time.
Parts used in the Digital Blood Pressure Meter:
- PIC24FJ128GC010 microcontroller
- MCP6N11 instrumentation amplifier
- Digital blood pressure meter demo board
This Application Note from Microchip provides a reference design for building a non-invasive blood pressure meter using the PIC24FJ128GC010 microcontroller and MCP6N11 instrumentation amplifier.
A digital blood pressure meter measures systolic and diastolic pressures by oscillometric detection. Microchip’s digital blood pressure meter demo can measure blood pressure and pulse rate during inflation. The Measurement While Inflating (MWI) principle reduces overall measuring time, which in turn reduces discomfort caused by the pressure in the cuff.
