Description
Technical Field
The invention relates to a traditional Chinese medicine pulse condition signal acquisition technology, in particular to a separable traditional Chinese medicine three-part pulse condition acquisition combined bracelet device.
Background
The "inspection and study" of the four diagnostic methods in traditional Chinese medicine is the intelligent crystal accumulated in ancient Chinese people in the process of seeking for treatment of diseases, and the pulse diagnosis is the content represented by the "diagnosis" and is an integral and important component of the traditional Chinese medicine. In recent years, the pulse-taking of traditional Chinese medicine is regarded as a non-invasive and painless detection means, and is appreciated and welcomed by people at home and abroad. However, the pulse diagnosis in traditional Chinese medicine also has some limitations, such as the pulse condition can be judged only by the finger feeling during pulse diagnosis, which is highly subjective and is prone to have deviation from the actual pulse condition. In addition, the talent culture in the aspect of pulse feeling in traditional Chinese medicine needs to spend a large amount of manpower and material resources, needs long-term practical experience, is difficult to say and inherit pulse feeling skills, and is not beneficial to the development and popularization of traditional Chinese medicine. Therefore, various research institutions and scholars at home and abroad develop pulse diagnosis objective research in recent years, mainly including three aspects of pulse signal acquisition, signal processing and analysis and pulse condition signal classification, and the development of pulse diagnosis standardization, informatization and intellectualization is gradually promoted.
In the research of pulse diagnosis objectification, the most important thing is the development of a pulse diagnosis device. In the pulse taking process of the traditional Chinese medicine, three-finger pulse taking is generally carried out in the cunkou area 'cunguanchi' of the radial artery of the wrist of a patient, and because the three parts of different people have differences, in the pulse taking process, the traditional Chinese medicine needs to adjust the positions of fingers to find the correct three parts, and then different pressures are applied to the three parts to feel the pulse through lifting, pressing and seeking so as to achieve the purpose of distinguishing diseases. Therefore, in the development process of pulse diagnosis devices, the devices should be designed to meet the functional requirements based on the pulse manifestation theory and diagnosis mode of traditional Chinese medicine. In summary, the pulse diagnosis device mainly includes the following aspects: the selection of the sensor, the design of the sensor position adjusting mechanism, the design of the sensor pressurizing mechanism, the design of the whole mechanical structure of the device and the design of related circuits.
In terms of sensor selection, pressure sensors, photoelectric sensors, and the like are frequently used in conventional pulse diagnosis devices. The photoelectric sensor can not obtain pulse pressure information when acquiring pulse signals, and in addition, the pulse condition information measured by the photoelectric sensor mainly refers to the change of blood flow volume in blood vessels, which has a certain difference with the pulse vibration strength sensed by the traditional Chinese medical fingers, and the conversion relationship between the pulse condition information and the pulse vibration strength needs to be deeply researched, so that the development of the photoelectric sensor has certain limitations due to the lack of the pulse condition information and the difference between pulse condition principles. In the aspect of sensor position adjustment, in the existing pulse condition pressure acquisition device, a single pulse condition is measured more, and a device for measuring three pulse conditions is difficult to accurately find the positions of the three parts of cunguan and chi due to the fact that the pressure sensor is large in size and limited in position adjustment range. In the aspect of pulse condition pressurization, there are three main ways of mechanical pressurization, pneumatic pressurization and liquid pressurization. At present, the pneumatic pressurization or liquid pressurization pulse condition acquisition devices are adopted, and the integral pressurization mode is adopted for the wrist cunt and mouth area, namely, the pressure adjustment cannot be carried out on the three parts, and the traditional Chinese medicine three-finger pulse taking and searching method cannot be simulated. When adopting mechanical pressurization mode, need spare parts such as motor, axle, the desk-top or the wrist strap formula device that the preparation formed, its volume size and weight are all bigger, and inconvenient carrying, in addition, when looking for three positions and carrying out add and subtract pressure, it is longer with the adjustment time to measure preparation in earlier stage, and the operation is not simple and convenient enough, needs the professional to guide and accomplish the collection work, is unfavorable for the intelligent development of pulse diagnosis, is not suitable for house medical treatment.

23) slowly and continuously pressurizing: the upper computer sends a serial port instruction to the single chip microcomputer, the off-position air pump starts to inflate and slowly pressurize, and the pulse condition sensor sends pulse condition signals under continuously increased pressure to the flexible circuit board;
24) signal processing and sending; after circuit differential amplification, filtering, alternating current amplification, direct current amplification, superposition and voltage lifting processing are carried out on signals of the off-position sensor, pulse condition pressure signals are respectively obtained from the output end of the voltage lifting circuit, pulse taking pressure signals are obtained from the output end of the direct current amplification circuit, and the pulse condition pressure signals and the pulse taking pressure signals are sent to an upper computer through a serial port;
25) searching for the best pulse taking pressure: the upper computer displays a pulse condition signal curve and a pulse taking pressure value in real time according to the received signal, and selects the corresponding pulse taking pressure when the peak-to-peak value is maximum as the optimal pulse taking pressure of the gateway part;
26) three pulse condition data under different pressures are obtained: the upper computer obtains the optimal pulse pressure according to the off position, sets a pressurizing range and divides pressure sections, the three parts start to pressurize simultaneously, the signals are sent to the upper computer after being processed, the testing time of 10s is kept under each section of pressure, so that stable pulse condition data under the pressure are obtained, and the upper computer obtains the data of the three pulse condition signals under different pressures according to the obtained data;
under the three bracelet combination assembly pulse condition mode, adjust the relative position between the bracelet through set screw and guide vane for confirm the position of cun guan chi, relative position between the bracelet is adjustable along the pulse length direction and along the pulse width direction, and the adjustment range of each pulse condition collection bracelet along the pulse length direction is 0-5.5mm, and the adjustment range of along the pulse width direction is 0-10 mm.
