资料介绍

血压检测对疾病预防和治疗具有重要作用,对危重病人和手术中的病人还需要血压连续监护,以便病人出现意外时医护人员能及时采取救护措施.本文提出了一种无损、快捷的血压计的电路设计和实现方法.首先,系统通过硬件采集电路完成信号的采集以及预处理,再利用微控制器进行信号的A/D转换、存储,所得参数在液晶屏上显示.该电路经过实物样机测试,完全达到实际使用要求,具有安全、可靠等优点.

Detection to blood pressure has a major significance in the prevention and treatment of diseases. In order to prevent the patient from a clinical accident, it also need to continuously monitor blood pressure on critically ill patients and surgical patients, so that the patients can be treated and rescued as soos as accident occur. This paper presents a nondestructive and fast design and realization method of sphygmomanometer. The circuit system finishes collecting and preprocessing signals through hardware acquisition circuit, proceeding A/D conversion and storage by using MCU, and playing the parameters on the LCD panel. The prototyping test indicated that the circuit completely achieved the actual request and practice safely and reliably.
