Description

The present invention relates to an apparatus that assists a doctor in diagnosis by pulse diagnosis by image information processing inference using electric signals. In Chinese traditional medicine, pulse diagnosis occupies an important position as one of the diagnostic methods. However, this is largely due to the accumulated experience and intuition. As shown in Fig. 1, the common place for pulse diagnosis in traditional Chinese medicine is the thumb side of the left and right wrists, inside the radial styloid process, above the radial artery, and from here almost at the fingertips. Dimension (111) (121), Seki (112) (12)
2), a total of 6 measures (113) (123), and 2 sets of pulse check points (114) (124) each. In addition, in diagnosing the pulse, the doctor applies his fingertip to the patient's pulse point, dimension, function, and scale,
By applying some pressure, the pulsations in response to this pressure are sensed. The present invention will be described below by way of its examples. As shown in FIG.
0), a pulsating signal matching circuit (212), a phase linear characteristic low pass filter circuit (Bessel filter) (213), an analog / digital conversion circuit (214), a computer system (215), and a display device (216), The pressure signal matching circuit (222), the analog / digital conversion circuit (223), and the numerical display device (224) are used as a basic configuration. The palpator (200) is constructed as shown in FIG.
A small microphone is used as the pulsation detector (211), and a small pressure sensor is used as the pressure detector (221). The small microphone (211) is attached to one end of the cylindrical container (31) which is elastic and is capable of expanding and contracting in the lengthwise direction.
2) are closely attached so that they come out of the cylinder (31), the other end of the cylinder (31) is connected to a flexible thin tube (33), and the other end of the thin tube (33) is connected to the pressure sensor (221). It is connected to the pressure detection port (34) and has a structure in which a medium (35) such as a liquid is filled inside the cylinder (31) and the thin tube (33). Use this palpator (200) to measure the pulse size (111) (1
21), Seki (112) (122), Shaku (113) (12)
By hitting 3), the microphone (211) catches the pulsation as a vibration sound and converts it into an electric signal. In addition, at this time, the minute pressure that the doctor applies to the patient's pulse check point causes minute expansion and contraction of the cylinder (31) and is transmitted to the pressure sensor (221) using the internal liquid as a medium, where an electric signal is transmitted. Is converted to. The signal from the microphone (211) is a pulsating signal matching circuit (212) including an amplifier and an attenuator.
In addition, unnecessary frequency components, noise, etc. are removed by the filtering circuit (213), and the computer system (215) is passed through the analog / digital conversion circuit (214).
To enter as data. Also pressure sensor (221)
Signal from the pressure signal matching circuit (222),
The signal level is adjusted to an appropriate level, and this is converted into a digital signal by the analog / digital conversion circuit (223) and input and displayed on the numerical display (224), whereby the doctor confirms the depth of the layer in the pulse diagnosis. On the other hand, the data input to the computer system (215) is temporarily stored and stored, and if necessary, waveform analysis is performed to determine the waveform shape,
Changes in frequency, interval, etc. are displayed as an image, and by this change,
By performing processing based on the fuzzy theory, the medical condition is inferred and diagnosed. In pulse diagnosis in medical diagnostic technology, do not rely only on experience and intuition by the fingertips of doctors,
This method of expressing the state of the pulse in an image and diagnosing the information obtained from this image by fuzzy reasoning is extremely effective. The pulse is a reaction of human life, and if the present invention can support the objective pulse diagnosis, the pulse diagnosis technology can be further promoted.
