The paper explains the causes of incorrect sphygmogram recording and describes the physical principle of a pulse wave recording device, its designing and technical features. Evidence is given for the advantages of pneumatic pressing over mechanic one, thereby enhancing the reproducibility and accuracy of pulse wave recording. Trials have indicated that the use of the proposed device needs much less time for making pulse diagnosis.
The paper provides numerical calculations of module-argument relationship of the transducing function of a pulse signal force transducer in the multiarea pulse diagnostic device to the parameters of the oscillation system. It is shown that free oscillations of the low-frequency oscillation system at 300 pi rad/c or more may yield allowable phase and amplitude-time distortions of signal A transduction, with real values of damping of a low-frequency part of the oscillation system, the noninformity of amplitude-time characteristics is no more than 30% in the working frequency range of the force transducer.
