Description
Technical Field
The utility model relates to an automatic technical field of traditional chinese medical science pulse diagnosis, concretely relates to pulse condition acquisition equipment based on high-speed camera technique of high definition.
Background
The pulse condition of traditional Chinese medicine contains rich biological information, and is an important content of the four diagnostic methods of traditional Chinese medicine. The pulse is called pulse condition, the image and dynamics of pulse. The pulse condition is closely related to the qi and blood of the zang-fu organs. Jin, Wang Tertiary and Mai Jing summarize the pulse conditions into twenty-four kinds; ming, Li Shizhen (from Binhu Mai Xue (science of the lake of Binghu)) defines twenty-seven pulses; ming Li Shi material (Zhen Jia Zheng Yan) enters Ji Mai, and twenty-eight pulse conditions. The twenty-eight pulses are used in the later generations.
The pulse condition elements refer to the basic components of the pulse condition, including the four aspects of position, number, shape and potential. The artificial pulse condition is mainly recognized by the sense of fingers. The pulse conditions are of various types, and the Chinese medicine literature usually analyzes and summarizes the four aspects of position, number, shape and potential, and is related to the frequency and rhythm of the pulse, the presented position, length and width, the fullness and tension of vessels, the smoothness and fluency of blood flow, the strength and weakness of heart pulsation and other factors. Mastering the pulse condition factors can play a role in simplifying and managing the pulse condition to understand the characteristics and formation mechanism of various pulse conditions.
A pulse position: refers to the position and length of the pulse. Each pulse should be examined for the depth and length of the pulse. The normal pulse is not superficial and deep, and the cun, guan and chi regions have pulses. Superficial pulse refers to superficial pulse; deep pulse refers to deep pulse; the pulse over cun, guan and chi regions is the long pulse, while the pulse under cun and chi regions is the short pulse.
The second pulse is rapid: the number and rhythm of the pulse beat. Each pulse should be examined for the frequency and rhythm uniformity. In normal adults, the pulse rate is about 70-90 pulses per minute with a uniform rhythm and no pause. For example, five to more pulses are counted; the pulse is delayed when the pulse is less than four; the intermittent pulse-promoting, pulse-connecting and pulse-substituting herbs are different; the irregular rapid and slow pulse is marked by the three or five disharmony, with the scattered and astringent pulses.
Three-pulse shape: the pulse width is the form of the pulse beat. The pulse should be examined for the size, hardness, etc. of the pulse each time. The pulse shape is mainly related to the filling degree of the vessels, the amplitude of the pulse wave and other factors. For instance, the vessels are full, and those with large pulse amplitude are surging; the vessels have small filling degree, and the ones with small pulse amplitude are thready vessels; the wiry pulse is the one with poor elasticity and not soft; the soft and weak pulse is called soft pulse or slow pulse.
Four pulse conditions: this refers to the tendency of strong, weak and smooth pulse. The pulse condition includes various factors, such as the axial and radial strength of the pulsation; fluency mainly results from cardiac and resistance effects; the degree of tension due to the influence of the elasticity and tension of blood vessels, etc. Each pulse should be examined for the strength and smoothness of the pulsating force. The normal pulse condition should be gentle and moderate. Forceful is an excessive pulse; weakness of the fingers is the deficient pulse; the smooth state is better, and the smooth pulse is smooth; those with poor unobstructed state and difficult and unsmooth pulse are astringed pulse.
The above are the basic elements constituting the pulse condition and the basic key points for physical inspection of the pulse condition. The pulse condition is distinguished mainly according to the feeling of the physician under the finger, so that the physician must repeatedly practice the finger feeling, carefully and physically examine the pulse, and analyze the various pulse condition elements to form a more complete pulse condition, so as to correctly distinguish the various pulses.
Pulse diagnosis relies on the tactile function of the tips of human fingers. Human skin can sense various senses such as touch sense, pain sense, heat sense and the like, wherein the touch sense is particularly important. The human touch is mainly perceived by 4 tactile receptors among a large number of mechanoreceptors distributed at different depths in the skin: the Meissner corpuscle in the surface layer skin and the annular corpuscle in the deep layer skin are both fast adaptive receptors, the Meissner corpuscle can fast respond to external stimulation with a narrow low-frequency dynamic range of 3-40 Hz, and the sensory functions of low-frequency vibration, motion detection, grip strength control and the like are realized; the high-frequency vibration sensor can quickly respond to external stimulation with a wide high-frequency dynamic range of 40-500 + Hz, and achieves the sensory functions of high-frequency vibration, tool use and the like. In contrast, a merkel cell with short finger-shaped protrusion distributed among basal cells of the epidermis of the whole body and a long fusiform rufenib corpuscle in the dermis are slow adaptive receptors, the merkel cell can slowly respond to external stimuli such as narrow low-frequency dynamic range of 0.4-3.0 Hz, continuous pressure, curved surface, edge or sharp angle and the like, and the mode/form detection, texture perception and the like are realizedSensory function; the device can slowly respond to external stimuli such as continuous downward pressure, transverse skin stretching, skin sliding and the like with a wide high-frequency dynamic range of 100-500 + Hz, and achieves sensory functions such as finger position, stable grabbing, tangential force and motion direction. According to the characteristics of tactile perception, the tactile sensation can be divided into a sliding tactile sensation and a flexible tactile sensation. The sliding touch sense is the perception parallel to the finger contact surface and mainly reflects the geometric shape, texture, temperature and the like of the surface of an object; the flexible touch sense is dynamic perception in a direction perpendicular to the finger contact surface and mainly reflects the flexibility or rigidity of an object. The distribution density of the tactile receptors on all parts of the human body has large difference. 241 cm and 58cm are distributed on the finger tip and palm center of the adult respectively2The space resolution of each part of a human body is obviously different by the tactile sensor, the space resolution of the fingertip is 0.2mm in depth sense, the distance between two points is 0.5mm, and the critical tactile response time of two events at different positions is 30-50 ms. Controlled pressure sensitivity studies show that: the normal pressure thresholds for the male palms and fingertips are on average about 0.158g and 0.055g, respectively, and for the female 0.032g and 0.019g, respectively.
The traditional Chinese medicine pulse-taking is the finger tip feeling of traditional Chinese medical doctors, and the density of the receptors of the finger tips of human beings is the highest, so that the traditional Chinese medicine pulse-taking has rich information and high precision. To realize the objectivity of the pulse-taking in traditional Chinese medicine, the sensor needs to reach certain indexes of a human finger tip receptor in the aspect of acquiring pulse-taking information so as to accurately distinguish different pulse conditions.
In the middle of the 50 s of the 20 th century, scientists in the Chinese medicine, Chinese and Western medicine combination and biomedical engineering circles began to objectively study the pulse condition of Chinese medicine. Since then, japan, korea, and the united states, etc. have engaged in this work. In general, the pulse diagnosis objective research focuses on the research of pulse condition detection sensors.
The traditional pulse detection method is finger palpation, which inevitably brings subjective factors, is inconvenient for objective recording and fine analysis, is difficult to inherit and innovate, and greatly limits the application and popularization of the pulse detection method. The sensor is adopted to detect the pulse, so that the main information of the pulse can be objectively obtained, the pulse wave signal is recorded, the storage and the analysis are facilitated, no wound is caused to a human body, and the use is convenient, so that the sensor is widely applied in practice.
A pulse condition detection sensor creates a first lever type pulse recorder as early as 1860 Vierordt, the development of traditional Chinese medicine pulse recorders is fast at home and abroad, particularly, a interdisciplinary pulse condition research cooperation group is successively established at the middle 70 s in China in Tianjin, Shanghai, Guizhou, Jiangxi and the like, and the multi-disciplinary co-cooperation promotes the traditional Chinese medicine pulse condition research work to enter a new border.
The pulse condition detecting sensor has many types, including single-part, three-part, single-point, multi-point, rigid contact, soft contact, hydraulic, silicon cup type, liquid mercury, liquid water, primary and secondary type, etc. The main components of pulse probes include strain gauges, piezoelectric crystals, single crystal silicon, photosensors, PVDF piezoelectric films, and the like, and among them, single-point strain gauges are the most widely used, but in recent years, three-point multi-point probes are developed. However, the pulse sensors developed at home and abroad can only collect the information of pulse pressure and pulsation and cannot represent other multidimensional information.
The objective pulse diagnosis research shows that the arterial pulse not only sends out the information of pressure pulsation, but also has various information such as lumen volume, blood flow velocity, three-dimensional motion of vessels, and the like, namely four aspects such as position, number, shape, and potential of the pulse condition. The pressure pulse diagram acquired by only using traditional sensors such as a pressure sensor and the like is difficult to quantitatively reflect indexes of pulse condition constituent elements (some pressure pulse diagrams are converted into three-dimensional images through multi-point pressure information, but due to the fact that acquisition points are insufficient, the accuracy of the pressure information is poor, and three-dimensional reconstruction is not accurate enough). Therefore, on the basis of the existing automatic pulse condition analysis and research results, the holographic synchronous acquisition of pulse conditions such as pulse condition information pressure, three-dimensional motion and the like is realized by fully utilizing a three-dimensional image acquisition technology, an artificial intelligence technology and an automatic control technology, and the method has important significance for providing a solution for realizing the objectification of the pulse diagnosis of the traditional Chinese medicine and promoting the inheritance and innovation of the traditional Chinese medicine.
In recent years, pulse condition three-dimensional information acquisition methods (CN107466222A, CN1927114A) based on structured light and binocular vision technologies have appeared, and there are methods using sensor arrays, but these methods do not achieve sufficient accuracy, are difficult to miniaturize both on the technology and the equipment, and cannot really achieve multi-dimensional information synchronous acquisition in acquiring pulse condition information, so there is room for continuous improvement.
