日常所见的血压计主要分为水银柱式血压计和电子(无液)血压计两大类。由于水银柱式血压计体积较大,携带不方便,所以在日常家庭中应用不是很广泛。电子血压计体积小,携带方便,使用亦比较方便,几乎所有的人都可以自己使用,作为自我简单检查血压的工具很受高血压患者的欢迎。但在使用过程中,很多人都对其不太了解,认为用它测得的血压与水银血压计测得的值不相符,有误差。对此作者从两者的测量原理、可靠性分析、操作难易、及安全性方面对二者进行对比。
Daily sphygmomanometer can be divided into mercury sphygmomanometer and electronic (no liquid) sphygmomanometer two categories. As the mercury sphygmomanometer bulky, inconvenient to carry, so the application in the daily home is not very wide. Small electronic sphygmomanometer, easy to carry, use is also more convenient, almost all of them can use their own, as a simple self-examination of blood pressure tools are very popular with hypertensive patients. However, during use, many people do not know much about it and think that the blood pressure measured by it does not match the value measured by a mercury sphygmomanometer, with errors. The author compares the two from the measurement principle, reliability analysis, easy operation, and safety.
