Description
Technical Field
The utility model relates to a pulse condition acquisition sensor, which belongs to the technical field of pulse diagnosis informatization of traditional Chinese medicine.
Background
The formation and development of traditional Chinese medicine have been 5 thousand years old, researchers developed modern research of traditional Chinese medicine as early as the 19 th century and the 80 th century, wherein the research on pulse diagnosis in traditional Chinese medicine still mainly focuses on the pickup of pulse conditions and the analysis of pulse condition graphs, and only a small part of scholars begin to pay attention to pulse simulation inversion, so that no traditional Chinese medicine diagnosis and treatment product is applied to clinic.
The traditional Chinese medicine is empirical medicine formed in the process of thousands of years of development and practice of Chinese nationalities, and diagnosis and treatment means of the traditional Chinese medicine are more important than visual description and have larger subjective randomness. Especially in the pulse diagnosis, the expression of the difference between different pulse conditions is too fuzzy, which makes the development and inheritance of traditional Chinese medicine difficult, and further brings up a schedule for the objective research of pulse conditions.
Although various types of pulse instruments visible in the market are available, the pulse instruments are not perfect in effect in practical application, and therefore, the pulse instruments are not popularized vigorously. The main reason is that different pulse taking methods of doctors in traditional Chinese medicine are completely different in pulse diagnosis, because although pulse conditions exist objectively, pulse condition feedback information caused by different pulse taking methods is different, and the interaction process of different fingering actions and finger pulse condition feeling is realized, and complete pulse condition collection cannot be completed only by fixed pressing of a sensor. Meanwhile, because a large amount of pulse condition data support does not exist, analysis models of various pulse conditions cannot be completely established, so that the whole-course recording of the pulse feeling process, and the interaction equipment and the terminal of the pulse condition and the pulse feeling, which can really meet the requirements of traditional Chinese medicine, are not really researched.
With the development of traditional Chinese medicine, the inspection and the inquiry of the four diagnostic methods are the basis of the complementary diagnosis of traditional Chinese medicine, wherein the pulse diagnosis is an indispensable part of the clinical diagnosis of traditional Chinese medicine, and the core of the digitization of the pulse diagnosis lies in the extraction of pulse condition signals. Because the pulse amplitude of the human body is weak, the pulse is easily interfered by other noise signals during acquisition, and certain difficulty is added to the extraction of the pulse condition. How to accurately acquire the pulse condition puts forward a certain demand on the performance of the pulse condition acquisition sensor.
The piezoresistive pulse sensor has the advantages of simple structure and wide dynamic range, but is greatly influenced by the ambient temperature and the like, and the piezoresistive pulse sensor with high precision has complex manufacturing process and higher manufacturing cost; the piezomagnetic pulse sensor has simple structure, firmness, reliability and strong anti-interference performance, but has general precision and less research; the photoelectric pulse sensor is simple in structure, non-contact in measurement and good in repeatability, but mainly detects the transmittance of a human body, so that the photoelectric pulse sensor is mainly used for fingers and is not in accordance with the original diagnosis mode of traditional Chinese medicine; because the pulse beat can generate an acoustic signal, the microphone can also be used as a pulse sensor, the structure is simple, but the coupling of human skin is not easy, and the energy loss is serious; ultrasonic Doppler is mainly used for measuring the blood flow velocity, the blood vessel wall and other conditions, can be used for pulse measurement, but is expensive in equipment price, is non-contact measurement and is not in accordance with the finger pressure diagnosis mode of traditional Chinese medicine; the piezoelectric pulse sensor has the advantages of simple structure, high precision and sensitivity, no power consumption and superior performance, and is a passive device.
SUMMERY OF THE UTILITY MODEL
In order to solve the problems existing in the prior art, the utility model provides a pulse condition acquisition sensor.
The utility model discloses a pulse condition acquisition sensor adopts technical scheme as follows:
the pulse condition acquisition sensor's base is hollow cylinder, and open the side has two through-holes, and two copper lines are introduced at the bottom surface center on the base, and the copper line is drawn forth separately from the through-hole respectively, bottom surface paste has polyvinylidene fluoride piezoelectric film under the base, to polyvinylidene fluoride piezoelectric film both wings oblique cutting fifty percent discount, with the interior copper line UNICOM of through-hole.
Further, the base is made of plastic insulating materials.
Furthermore, two wings of the polyvinylidene fluoride piezoelectric film are connected with the copper wire in the through hole through conductive silver adhesive.
Furthermore, the polyvinylidene fluoride piezoelectric film adopts a bonding mode of bonding the periphery and suspending the middle.
Furthermore, the polyvinylidene fluoride piezoelectric film is made of a polyvinylidene fluoride material which is subjected to polarization treatment under the environment of high temperature and applied electric field.
