A pulse waveform of a living body is detected and is analyzed using peak point data or timing data to perform a diagnosis of a condition of the body.

Diagnostic apparatus for analyzing arterial pulse waves

A pulse wave analyzing apparatus that detects a pulse wave from a living body and computes a waveform distortion factor and determines a waveform shape for performing a diagnosis of a condition of the living body.

The present invention relates to a diagnosis apparatus for analyzing arterial pulse waves comprising a database in which is stored data showing the relationship between data representing a pulse wave of a living body and teaching data representing conditions of the living body; and a micro-computer for outputting teaching data corresponding to the pulse wave detected from the living body in the teaching data on the basis of the pulse wave detected from the living body and the stored data inside database . As a result, it becomes possible to perform diagnoses equivalent to a skilled doctor.

The present invention relates to a diagnosis apparatus for analyzing arterial pulse waves comprising a database 26 in which is stored data showing the relationship between data representing a pulse wave of a living body and teaching data representing conditions of the living body; and a micro-computer 21 for outputting teaching data corresponding to the pulse wave detected from the living body in the teaching data on the basis of the pulse wave detected from the living body and the stored data inside database 26. As a result, it becomes possible to perform diagnoses equivalent to a skilled doctor.

A pulse wave analysis device for analyzing the condition of a human body is disclosed. A cuff band is wrapped around the tip of the second finger of a subject's hand. When the operator depresses the beginning-of-measurement key, the finger tip is pressed at various pressures by means of an air pump and a pressure sensor. Pulse wave signals at different pressure values are automatically measured by an optical fingertip plethysmogram sensor. The signals are transmitted to a CPU through a BPF, an amplifier, and an ADC. The CPU performs FFT analyses on the signals and determines to which pattern from among the patterns stored in a ROM the pattern level of the pulse wave spectrum for a given pressure value is closest, and displays the result on a display unit as a test result indicating the viscoelasticity of the subject's peripheral circulation tissue.

Pulse wave analysis device

A microcomputer performs a frequency analysis of pulse waves which are taken at regular time intervals from a patient through a pulse wave detection section. Then, if the amplitudes and phases of the spectra of the pulse waves fulfill some set conditions, either .alpha.-blocker or .beta.-blocker is given to the patient, and the patient's circulatory activity is maintained in a stable condition.
