Abstract
A method for measuring the pulse wave on the wrist based on a multipoint sensor with a fiber-optic transducer probe is proposed. The development and current state of techniques for recording the radial artery pulse wave signal are analyzed. It is noted that the problem of comfortable pulse wave detection without reinstalling the sensor has not yet been solved. The possibility of reducing the distortions in the pulse wave signal using the method of superposition of readings of reinstalled single-point sensor is considered. It was shown experimentally that at any position of the proposed sensor it is possible to reliably measure the pulse wave signal. Amplitude changes in the measuring channels corresponding to the displacement of the radial artery apex relative to the sensor could be traced in the recordings. Thus, it can be concluded that it is possible to design a mobile medical device for comfortable measurement of the pulse wave, which does not require special skills when installing the sensor. A name for such a device − matrix analyzer of pulse wave (MAPW) − is suggested.
