Study on Reillumination of Hi-soo type Electronic Manometer

희수식 전자 맥진기의 재조명

In early 1970s, Electronic Manometers were researched and developed for modernization and objectification of pulse diagnosis. Method of finger pressing, also known as cuffs pressing, is essential for sensing a pulse wave. I think comprehension and deduction of problem from the existing Hi-soo type electronic manometer, will be important for making a better one. The Hi-soo type electronic manometer is constructed of cuff pressing type sensor, differential amplifier, transmitter and recorder. Pulse movement and pulse wave, gauging blood flow, is analyzed by pulse image of "Yixuerumen(醫學入門)". At standard of pulse wave, huanmai(緩脈) is distinguish from chishu(slow and fast, 遲數), fushen(float and sink, 浮沈), interference wave, modificated wave, and phase angel. The Hi-soo type electronic manometer had no explanation of formational mechanism, significantly different with pulse wave which is early known and reported. The strength of Hi-soo type electric manometer is use of cuff pressing type sensor. Above all, the importance of electric manometer is reading the pulse movement accurately then expressing it as pulse wave. From now on the improvement of precise sensor should make a progress.
