近年来,医用电子学方面发展相当迅速,从人体各种生理指标的自动检测到电子计算机用于诊断、治疗与监护已形成综合的电子医疗系统,这不但减轻了医务人员工作的紧张程度(抢救和手术时),而且也有效地避免了人的感观失误,使医疗质量大为提高。血压是最重要的生理指标之一,因此血压测量技术的改进有着重要的意义。 In recent years, there has been a rapid development in medical electronics. From the automatic detection of various physiological indicators of the human body to the formation of a comprehensive electronic medical system for diagnosis, treatment and custody of electronic computers, this not only alleviates the strain on the work of medical personnel And surgery), but also effectively avoid human error perception, the medical quality greatly improved. Blood pressure is one of the most important physiological indicators, so the improvement of blood pressure measurement technology is of great significance.
