Abstract

A method and apparatus for diagnosing the circulation of blood. A pressure measurement instrument is provided to measure the waveform of the blood pressure in an artery of a patient. An analyzer is employed to analyze the frequency components of the blood pressure wave in order to compare the pattern of each resonance component to the pattern of a normal blood pressure wave in order to determine whether the blood distribution of the patient is off-balance. This off-balance can be diagnosed from the Chinese medicine principles by relating each harmonic in the blood pressure wave to the corresponding meridian which includes a specific organ. If a specific problem or disorder is identified, the effectiveness of any treatment can be monitored by following the change in the specific harmonic component in the blood pressure wave. This method can also be a valuable medical tool in the development of new treatments or drugs. The analyzer includes a device for analyzing the amplitude and the phase of the resonant frequencies in the blood circulation of the body, and includes a transducer attached to or closely adjacent to the surface of an artery of the body of the patient. The analyzer includes a computer for analyzing the frequency spectrum of blood pressure in the artery for determining characteristics of the frequencies of the meridians of the body and for diagnosing whether the meridian is in trouble.
