Optimal design of portable ambulatory blood pressure monitor based on STM32L / 中国医疗器械杂志

ABSTRACT

Based on the 32-bit ultra low power microcontroller STM32L151RBT6 using ARM Cortex-M3 kernel, the portable ambulatory blood pressure monitor powered by two AA batteries was designed. In order to insure the stability of power supply and prevent overpressure of cuff, super capacitor technology and new kind of safety logic circuits were used. The experimental result shows that this solution is accurate and stable, which has high safety coefficient and a great clinical application value.
