Description

Equipment and method for automatically acquiring pulse condition five-dimensional information based on laser three-dimensional scanning

Technical Field

The invention relates to the technical field of automation of pulse diagnosis in traditional Chinese medicine, in particular to equipment and a method for automatically acquiring five-dimensional pulse condition information based on laser three-dimensional scanning.

Background

The pulse condition of traditional Chinese medicine contains rich biological information, and is an important content of four diagnostic methods of traditional Chinese medicine. The pulse refers to the appearance of the pulse (finger) and refers to the appearance and dynamics of the pulse. The formation of pulse conditions is closely related to qi and blood of viscera. Jing, wang-t He pulse channel summarize the pulse condition into twenty-four; ming-Li Shizhen (on the verge of lake pulse theory) is defined as twenty-seven pulses; ming-Li Shicai "Zhu Jia Zheng Yan" adds to the disease pulse and closes twenty-eight pulse conditions. Twenty-eight pulses are commonly used in the late stage.

The pulse condition element refers to the basic components of the pulse condition, including four aspects of position, number, shape and potential. The identification of the artificial pulse condition mainly depends on the feeling of the finger. The pulse condition is very various, and the Chinese medicine literature is often analyzed and summarized from four aspects of position, number, shape and potential, and is related to factors such as the frequency, rhythm, presented position, length and width of pulse, the fullness and tension of a vessel, the smoothness of blood flow, the strength and weakness of heart beat and the like. The control of the pulse condition elements can play a role in simplifying and controlling the formation mechanism and the characteristics of various pulse conditions.

One pulse bit: refers to the location and length of the pulse beat. Each time a pulse is diagnosed, the depth and length of the pulse manifestation should be examined. The normal pulse is not superficial and sinking, and the three pulses of cun, guan and chi are available. If the pulse is superficial, it is a superficial pulse; deep pulse refers to deep pulse; the pulse above the cun, guan and chi regions is a long pulse, while the pulse below the cun and chi regions is a short pulse.

Two pulse numbers: refers to the number and rhythm of pulse beats. Every pulse diagnosis should examine whether the pulse rate and rhythm are uniform. The frequency of the pulse is about 70-90 times per minute for normal adults, and the rhythm is uniform without stopping. For example, one-rest five to more than one pulse; one breath is not full of four to a delayed pulse; the intermittent pulse is the pulse that promotes the pulse, knots and pulses; uneven pulse rate is marked by irregular three-five pulse, and there are scattered pulse and astringent pulse.

Three pulse shapes: the pulse width and the like. Each time a pulse is diagnosed, the size, hardness, etc. of the pulse should be examined. The pulse shape is mainly related to factors such as the filling degree of the vessel, the amplitude of the pulse wave, etc. If the vessel is filled, the pulse with larger amplitude is a flood pulse; the pulse tube is smaller in filling degree, and the pulse amplitude is smaller as thin pulse; the poor elasticity of the vessel and the weak pulse are wiry pulses; soft and weak pulse can nourish the pulse and slow the pulse.

Four pulse potentials: the pulse refers to the trend of strong or weak pulse and smooth pulse. The pulse potential includes a variety of factors such as the axial and radial force of the pulsation; mainly the fluency created by heart and resistance effects; tension caused by the influence of vascular elasticity and tension, and the like. Each pulse diagnosis should examine the intensity and fluency of the pulse force. The normal pulse condition should mean mild and moderate. The strong pulse should be indicated; weak fingers are deficient pulses; the smooth state is good, and the smooth pulse is smooth; poor smooth condition, and difficult pulse condition, such as astringency.

The above is the basic element of pulse condition and the basic element of pulse condition observation. The pulse condition is distinguished mainly according to the feeling under the finger of the doctor, so that the doctor must repeatedly practice the feeling under the finger and carefully conduct physical examination, and the various pulse condition elements are integrated and analyzed to form a relatively complete pulse condition so as to accurately distinguish various diseased pulses.

Pulse diagnosis relies on the tactile function of the human finger tip. Human skin can sense a variety of sensations, such as touch, pain, heat, etc., with the sensation of touch being particularly important. Human touch is primarily perceived by 4 types of mechanoreceptors distributed in a large number of mechanoreceptors at different depths of the skin: the Meissner corpuscles in the superficial skin and the pericyclic corpuscles in the deep skin are fast adaptive receptors, the fast response of the fast response is 3-40 Hz low-frequency external stimulus with a narrow dynamic range, and the sensory functions of low-frequency vibration and motion detection, grip strength control and the like are realized; the latter can respond to external stimulus with wide dynamic range of high frequency of 40-500+Hz rapidly, and realize sensing functions such as high frequency vibration and tool use. In contrast, the mercer cells with short finger-shaped protrusions and the long spindle-shaped Lu Feini small bodies in the dermis, which are distributed among the epidermal basal cells of the whole body, are slow adaptive receptors, and the mercer cells and the long spindle-shaped Lu Feini small bodies can slowly respond to external stimuli such as spatial deformation, continuous pressure, curved surfaces, edges or even sharp corners with a narrow low-frequency dynamic range of 0.4-3.0 Hz, so as to realize sensory functions such as mode/form detection and texture perception; the latter can respond slowly to external stimulus such as continuous downward pressure, transverse skin stretching and skin sliding with wide dynamic range of high frequency of 500+Hz, and realize the feeling functions of finger position, stable grasping, tangential force and movement direction. According to the characteristics of haptic sensation, the haptic sensation can be classified into a sliding haptic sensation and a flexible haptic sensation. The sliding touch sense is a sense parallel to the contact surface of the finger and mainly reflects the geometric shape, texture, temperature and the like of the surface of the object; flexible touch is a dynamic perception in a direction perpendicular to the finger contact surface, primarily reflecting the flexibility or stiffness of the object. The distribution density of the touch receptors at each part of the human body is greatly different. 241 cm and 58cm are respectively distributed on fingertip and palm center of adult ² The tactile sensor has a significant difference in spatial resolution between parts of the human body, a fingertip spatial resolution of 0.2mm, a depth sense of 0.5mm between two points, and a critical tactile response time of two events at different positions of 30-50 ms. Controllable pressure sensitivity studies indicate that: the normal pressure thresholds for the palm and fingertip of the male were on average about 0.158g and 0.055g, respectively, and the corresponding values for the female were 0.032g and 0.019g, respectively.

The pulse diagnosis of traditional Chinese medicine is the feeling of the finger tip of the middle doctor, and the density of the human finger tip receptor is the highest, so the pulse diagnosis of traditional Chinese medicine has rich information and high precision. To objectify pulse diagnosis in traditional Chinese medicine, the sensor needs to achieve certain indexes of human finger tip receptors in pulse diagnosis information acquisition, and can accurately distinguish different pulse conditions.

In the middle 50 s of the 20 th century, the scientific workers in the world of Chinese medicine, chinese and Western medicine and biomedical engineering began the objective study of the pulse conditions of Chinese medicine. Thereafter, people in japan, korea, united states, etc. are engaged in this work. In general, the objective study of pulse diagnosis is focused on the study 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 used for detecting the pulse, so that the main information of the pulse can be objectively obtained, the pulse wave signal can be recorded, the storage and analysis are facilitated, the human body is not damaged, the use is convenient, and the method is widely applied in practice.

The pulse condition detection sensor creates a first lever type pulse recorder as early as Vierordt in 1860, and then development of the traditional Chinese medicine pulse recorder is fast at home and abroad, especially in the middle 70 s, the domestic Tianjin, shanghai, guizhou, jiangxi and the like sequentially form a interdisciplinary pulse condition research cooperation group, and the cooperation of multiple disciplines promotes the research of the traditional Chinese medicine pulse condition to enter a new boundary.

The pulse condition detection sensor has a plurality of patterns, including single part, three parts, single point, multiple points, rigid contact type, soft contact type, pneumatic type, silicon cup type, liquid mercury, liquid water, mother-son type and the like. The main elements of pulse probes are strain gages, piezoelectric crystals, monocrystalline silicon, photosensitive elements, PVDF piezoelectric films and the like, wherein single-point strain gages are the most widely used, but in recent years, three-point multi-point directions are being developed. However, the pulse sensors developed at home and abroad at present only can collect information on pulse pressure and pulsation and cannot represent other multidimensional information.

The objectification study of pulse diagnosis shows that the arterial pulse is not only the information of pressure pulsation, but also various information of lumen volume, blood flow speed, three-dimensional movement of vessel, namely four aspects of pulse condition such as position, number, shape and potential. The pressure pulse graph acquired by the traditional sensors such as the pressure sensor is difficult to quantitatively reflect the indexes of pulse condition components (some of the pressure pulse graphs are converted into three-dimensional images through multi-point pressure information, but the three-dimensional reconstruction is not accurate due to the fact that the acquisition points are insufficient and the accuracy of the pressure information is poor). Therefore, based on the existing pulse condition automatic analysis research results, the three-dimensional image acquisition technology, the artificial intelligence technology and the automatic control technology are fully utilized, the holographic synchronous acquisition of pulse condition information pressure, three-dimensional dynamic and other pulse conditions is realized, a solution is provided for realizing the objectification of pulse diagnosis of the traditional Chinese medicine, and the traditional Chinese medicine is promoted to inherit and innovate, so that the method has important significance.

In recent years, a pulse three-dimensional information acquisition method (CN 107468222A, CN 1927114A) based on structured light and binocular vision technology and a method adopting a sensor array are presented, but the methods cannot achieve enough precision, are difficult to realize miniaturization in technology and equipment, and cannot truly realize synchronous acquisition of five-dimensional information in the aspect of acquiring pulse information, so that there is room for continuous improvement.
