摘　　要：目的:设计血压柯氏音信号采集装置,用该装置实现基于柯氏音方法的血压测量。方法:通过传音器采集柯氏音信号,根据柯氏音信号出现和消失对应的袖带压力得到收缩压和舒张压,将该装置的血压测量结果与人工听诊法测量结果对比,验证结果的可信性。结果:2种方式得到的血压结果差别很小,用该装置测量血压结果是可信的。结论:用该装置可实现测量血压,进一步可以研究用该方法实现基于柯氏音原理的血压自动测量。Objective To design a device sampling Korotkoff s sound signal and acquiring blood pressure based on Korotkoff theory.Methods The author sampled Korotkoff s sound signal via microphone,and then according the cuff pressure corresponding to signal appearance and disappearance,the author acquired SBP and DBP.At last,the author validated the creditability by contrasting with the results of auscultatory method.Results The difference of SBP and DBP is near nonexistence,the blood pressure data using this device is creditable. Conclusion The blood pressure can be measured using this device, and it can be used to further study the auto-measurement of blood pressure base on Korotkoff＇s sound theory.
