基于MSP430的防水型电子血压计设计

Design of a Waterproof Electronic Sphygmomanometer Based on MSP430

为实现在洗浴、水下等特殊环境下对人体血压的实时监测,基于传统电子血压计的结构进行改进,设计出一种新型防水电子血压计,该系统可浸入水中正常工作。该系统采用TI的MSP430FG449型高速单片机作为控制核心,设计基于MP3V5050DP压力传感器的血压监测电路,可最大限度减少外围电路,实现系统体积小、功耗低、速度快等特性。经过全面的测试与调试,系统工作正常,并能获得良好的实验结果与血压监测曲线。

In order to realize monitoring blood pressure in real time for people in special conditions such as bathing or working in water, a waterproof electronic sphygmomanometer is designed, which can work normally when immersed in water, as a result of structure modification based on traditional electronic sphygmomanome- ter. In this system, the high speed microchip MSP430FG449 from TI Company with varieties of in-chip func- tions is used as the control center, and the blood pressure monitoring circuit by means of pressure sensor of MP3V5050DP is designed. In this way, it can decrease the peripheral units and circuits, in order to implement the characteristics of small volume, low consumption and high speed. After complete testing and debugging, this system operates normally, and good experiment data and blood pressure monitoring curve can be obtained.
