摘要
基于ARM Cortex-M3内核的32 bit超低功耗微控制器STM32L151RBT6,研制出由两节5号电池供电的便携式动态血压监测仪:提出运用超级电容技术解决电源稳定性问题,并设计新型安全逻辑电路来防止袖带过压。实验结果表明,该解决方案准确稳定且安全系数高,具有很强的临床应用价值。
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.
