Abstract
Abstract A pulse diagnostic device has a pulse wave sensor, a pulse wave signal processing unit and a register--all connected in series. The sensor is provided with means for correcting its amplitude-frequency response to obtain a prescribed shape of the pulse wave signal. The processing unit has an amplifier, an analog-to-digital converter and an analyzer all connected in series for analyzing of the pulse wave signal shape according to prescribed parameters. The method of measuring a pulse wave using the pulse diagnostic device resides in the fact that the sensor is pressed to the wrist in the Cyn, Gyan and Chi points, regulating the force of pressure; in so doing, one creates a pressure force by hand and regulates the position of the sensor corresponding to the measurement of a surface and/or deep or full pulse, until the first maximum value of the maximum amplitude of a signal appears to be visually received in the register.
