Description

Dual sensing pulse diagnosis instrument

Technical field

The invention relates to a dual-sensing pulse diagnosis instrument, in particular to a pulse function with an instant copying physician, which can copy the pulse experience of the physician and obtain the pulse-like experience of the pulse pulse when the pulse diagnosis instrument automatically synchronizes the pulse. Diagnostic experience data visualization of the pulse diagnosis platform. Background technique

The quantification of TCM pulse diagnosis has been carried out in China, Japan, South Korea and the Western world for more than 40 years. It has accumulated considerable results from the single point of single-point, such as the Taiwan Invention Patent Notice No.

No. 125470 discloses an automatic pulse device. This patent suggests the feasibility of quantification of pulse diagnosis. However, it is a single-point single-point pulse method, and the pulse information is extremely limited. On this basis, the mechanism of the pulse phenomenon is further explored. For example, the Taiwanese Invention Patent Bulletin No. 176587 proposes a pulse wave resonance theory to verify the correspondence between each harmonic and each viscera. In addition, Taiwanese Invention Patent Publication No. 200814966 proposes the correlation between the time domain pulse wave map and the cardiovascular system and the frequency domain diagnosis of the cardiovascular microscopic changes, integrating the idea of obtaining pulse wave information from both the time domain and the frequency domain. However, the above methods are all single-point single-pulse acquisition in the pulse, which is slightly inadequate in comprehensive information and decoupled from the accumulation of huge clinical data in traditional pulse diagnosis. It is a pity.

In addition, in order to explore the doctor's pulse-sensing design, the design of the finger-type pulse diagnosis device, such as the Taiwanese Invention Patent Notice No. 325402, proposes a multi-information measurement method including pulse pressure, temperature, displacement and voltage, and also allows the physician to finger The sensing device is inserted to assist in the accuracy of the diagnosis. However, due to the thickness and softness of the sensor on the sensing device, the doctor did not actually experience the pulse of the doctor. In addition, the Taiwanese Invention Patent Publication No. 200819109 has also designed a finger-type pulse diagnosis instrument for solving the standardization of pulse pressure. However, this method makes the reproducibility and automation of the pulse image difficult to achieve due to the thickness of the sensing device and the manner of finger-wearing.

Therefore, in order to obtain the pulse information comprehensively, the Chinese invention patent No. CN1595335 designs the pulse collection glove, the Chinese invention patent publication No. CN2649019 designs the pulse diagnosis sensor, and the Chinese invention patent CN101049247 designs the traditional Chinese pulse sensor. Three nine-time pulse detectors and pulse detection methods. This type of design suggests that if the pulse information is to be comprehensively obtained, the sensing device needs to be an array type. However, the physician's sense of the device may not be fully reflected by the thickness and softness of the sensing device. In order to automate the diagnosis of the pulse, it is necessary to find out the rules for the doctor to take the pulse. The design of the Taiwanese invention patent No. 200704392 "The ridge point measurement system and measurement method" and the Taiwanese invention patent publication 200727865 "three axes" The pulse diagnosis instrument and its diagnosis method are all open to the principle of optimal ridge point and pulse point.

In addition, in the academic literature, we can find that the current research on the pulse diagnosis instrument is not in the pulse diagnosis instrument itself, but in the following three aspects: pulse diagnosis procedure research, pulse wave characteristic research and pulse diagnosis comprehensive information research. The analysis is as follows: The pulse diagnosis program is mainly to explore how to obtain the optimal position of the pulse wave. For example, in the A Novel Noninvasive Measurement Technique for Analyzing the Pressure Pulse Waveform of the Radial Artery, the standard positioning procedure is proposed. When the amplitude of the pulse wave is the largest, it is the best pulse position [1]. This opens up a feasible way for the standardization of the pulse program. In addition, in the study of pulse wave characteristics, it can be divided into two aspects: one is to analyze the pulse wave as the frequency domain, and try to find the pulse feature by the harmonic analysis of the pulse wave [2]; the other analyzes the pulse wave in the time domain. The characteristics of each pulse are explored by the relationship between the peak value of the pulse wave, the sequence of the peak, and the rise and fall of the peak [3]. However, the above research is not a single single point pulse or three single point pulse, and can not see a comprehensive picture of the pulse. Therefore, Jin Guanchang developed two types of sensors with PVDF: one for three four-point total of twelve detection points to observe the spatial condition of the pulse wave; the other is a list of nine points for observing the pulse wave in the blood vessel The case of the section [4]. In addition, the Beijing College of Traditional Chinese Medicine has proposed three 5x5 points, each with a total of 25 points of micro-sensor arrays to obtain comprehensive information on the pulse [5].

Based on the above-mentioned patent literature and academic discussion, the common shortcomings of the existing pulse diagnosis apparatus are threefold: First, it is impossible to present, observe and record the sensation of the fingering and the finger-pulling (pulse) in the pulse process of the Chinese medicine practitioner. Come down. Second, the sensory device cannot fully reflect the feeling under the finger. Third, the criteria followed by the automated diagnosis of the pulse vein have not been established, so the depth of compression is not standardized. Moreover, due to the variety of pulse changes, the addition of traditional Chinese medicine to the teacher and self-feeling, often requires years of experience and try to figure out, and whether the pulse of self-perception is consistent with the classic description, it is difficult to get the correct answer. As Wang Shuhe, the author of The Pulse, said, "It is easy to understand in the heart," it reflects the difficulty of the traditional pulse diagnosis without objective evidence. The method of the pulse will vary from person to person, and the different ways of the lower finger will make the feeling of the finger different, resulting in the same patient in the clinic. The conclusions of different pulse will be obtained by different doctors. This phenomenon makes the application of pulse diagnosis limited to some extent, and also makes beginners It is very difficult to grasp the pulse diagnosis, and even lose the understanding of the importance of pulse diagnosis for the diagnosis of Chinese medicine, thus losing the interest in learning pulse diagnosis, and it has become a major obstacle to the development of pulse diagnosis of Chinese medicine.
