Description

Automatic Five-dimensional Pulse Information Acquisition Device Based on Three-dimensional Laser Scanning}

This utility model relates to the field of automatic pulse diagnosis technology in oriental medicine, and specifically relates to a device for automatically obtaining pulse image 5D information based on a kind of laser 3D scanning.

The pulse of oriental medicine contains a wealth of biological information, which is the important content of the four diagnostic methods of oriental medicine. The pulsation refers to the shape of the (finger) called a pulse, and refers to the shape and movement of the pulse. The formation of pulses is closely related to the intestines and gihyeol. Wang Sook-hwa of the Qin Dynasty compiled 24 pulses in 《Maekkyung》. Lee Si-jin of the Ming Dynasty defined it as 27 veins in 《Tachycardiology》, and Isajae Ming dynasty defined it as a total of 28 types of veins by adding disease veins in 《Jin Gajeongan》, and most of the later generations use 28 veins.

The pulsatile element refers to the basic constituent part of the pulsatile phase that includes four aspects such as location, number, shape, and energy. The artificial pulse is recognized mainly depending on the sense of the finger. There are many types of pulses, but in the oriental medicine literature, it is analyzed and inductive from four aspects, such as location, number, shape, and energy, and the frequency of pulse, rhythm, appearance area, length, width, swelling of the vasculature, tension, and smooth flow of blood flow. , Heart rate strength and weakness. By grasping the pulsatile element, we can easily understand the characteristics and formation mechanisms of various pulsatile patterns.

Pulse location: It refers to the area and length where the pulse appears. Whenever there is a pulse, the depth and length of the area where the pulse appears should be diagnosed. The part of the normal pulse can be obtained in the middle where it does not rise or sink, and the pulse can be felt in three parts of the chin, tube, and chuck. If the location of the vein is shallow, it is an arrhythmia, and if the location of the vein is deeply submerged, it is a needle vein. If the pulse exceeds three parts of the chon, tube, and chuck, it is a long vein, and if the pulse movement does not reach the chon and chuck, it is a short vein.

Number of pulses: It refers to the number and rhythm of the pulse. Whenever you lose heart, you should diagnose whether the pace and rhythm of your pulse is regular. The normal adult pulse frequency is 70-90 beats per minute, the rhythm is constant and does not stop. For example, if you breathe more than 5 times at a time, it is a vein, and if it is less than 4 times, it is a vein. When the pulse stops, there are various cases such as arrhythmia, condyle vein, and vena cava. If the rhythm of the pulse is irregular, there are mountain ranges and sharp veins.

Pulse shape: It refers to the shape of the pulse, such as the width of the beating. Whenever there is a pulse, the shape of the pulse should be diagnosed, such as the size and softness of the pulse. The shape of the pulse is mainly related to factors such as swelling of the vessel and the width of fluctuation of the pulse. If the vasculature is relatively swollen and the pulse width is relatively large, it is a red vein, and if the swelling of the vessel is small and the pulse width is relatively small, it is a vein. , Wanmaek, etc.

Pulse energy: This refers to trends in pulse strength and softness. The energy of the pulse includes a number of factors such as the axial and radial strength of the pulse, the softness caused by the influence of the heart and resistance, and the tension caused by the elasticity and tension of the blood vessels. Whenever there is a heartbeat, the intensity and softness of the pulse should be diagnosed. The normal pulse should be gentle, soft, and moderate strength. If there is strength in the pulse, it is a weakness, and if there is no strength, it is a weakness. If the state of the vein is relatively good without blockage and flows smoothly, it is a live vein, and if the vein is not smooth, it is a sap vein.

The above is a basic element constituting a pulse, and is also a basic element for diagnosing a pulse. Since the recognition of the pulse image mainly depends on the sense of the doctor's finger, the doctor who suffers from pain must repeatedly practice the sense of the finger and carefully examine the various elements of the pulse to comprehensively analyze various pulse elements to obtain a relatively perfect pulse image and accurately distinguish various veins. can do.

The pulsation depends on the tactile function of the human fingertips. Human skin can detect various sensations such as touch, pain, and heat, and among them, the sense of touch is particularly important. The human sense of touch is primarily detected through four tactile receptors among a large number of mechanical stimulus receptors distributed in the skin of varying depths. Both the Meissner corpuscle in the epidermal skin and the Parsini corpuscle in the deeper layers of the skin are quick adaptive receptors, and the former responds quickly to external stimuli in the low-frequency dynamic range of 3 to 40 Hz, realizing functions such as low-frequency vibration and motion detection and grip control. . The latter responds quickly to external stimuli in the 40-500+Hz high-frequency dynamic range, realizing sensory functions such as high-frequency vibration and the use of tools. In contrast, Merkel cells with a kind of terrestrial processes distributed between the basal cells of the epidermis of the whole body and the long fusiform Lupine corpuscle in the dermis are slow adaptive receptors, and the former are spatially transformed in the low-frequency dynamic range of 0.4 to 3.0 Hz, sustained. By slowly responding to external stimuli such as pressure, curved surfaces, edges or sharp edges, sensory functions such as mode/shape detection and texture detection are implemented, and the latter is a continuous downward pressure in the high frequency dynamic range of 100 to 500+Hz, transverse skin By gradually responding to external stimuli such as stretching and skin slipping, sensory functions such as finger position, stable gripping, tangential force and direction of movement are realized. According to the characteristics of tactile sensing, tactile sensation can be divided into sliding tactile sensation and flexible tactile sensation. The sliding tactile sense is a sensing parallel to the finger contact surface, mainly reflecting the geometric shape, texture, temperature, etc. of the object surface, and the flexible tactile sense is a dynamic sensing perpendicular to the finger contact surface direction, mainly reflecting the flexibility or strength of the object. The distribution density of tactile receptors in each part of the human body differs greatly. ^{Since 241 and 58 cm 2} tactile receptors are distributed on the fingertips and palms of adults, respectively, the difference in spatial resolution of each part of the human body is very distinct. The spatial resolution of the fingertips is 0.2mm in depth perception, 0.5mm in distance between the two points, and the critical tactile response time of two events at different locations is at the level of 30-50ms. According to a controllable pressure sensitivity study, the average of normal pressure thresholds for the male palm and fingertip were 0.158g and 0.055g, respectively, and the corresponding thresholds for women were 0.032g and 0.019g, respectively.

The pulse of oriental medicine is based on the sense of the fingertips of an oriental medicine doctor. Since human fingertips have the highest density of receptors, it is possible to obtain rich and highly accurate information through the pulse of oriental medicine doctors. In order to realize the objective pulse diagnosis of oriental medicine, the sensor can accurately distinguish various pulse images only when it reaches a specific index of the human fingertip receptor in the direction of acquiring pulse diagnosis information.

In the mid-50s of the 20th century, scientists in the fields of oriental medicine, eastern and western medicine and biotechnology in China first led the objective study of oriental medicine, and then Japanese, Korean, and American officials also participated in this work. Overall, the core of the study of objectification of pulses is the study of the pulse sensor.

The traditional pulse detection method cannot exclude subjective elements by finger palpation, objective recording and accurate analysis are not easy, and inheritance and innovation are also difficult, so there is a great limit to its application and popularization. Pulse detection using a sensor has been widely applied in practice because it can objectively obtain the main information of the pulse and record the pulse wave signal, it is easy to store and analyze, and it is convenient to use without harming the human body. .

After Vierordt developed the first lever-type pulse rate recorder in 1860 for the pulse sensor, research in the field of oriental medicine pulse measurement at home and abroad has been rapidly developed. In particular, in the mid-70s, interdisciplinary joint research teams were established one after another in Tianjin, Shanghai, Huizhou, and Jiangxi in Korea, and joint research in various fields took the research work of oriental medicine to a new stage.

There are many pulse sensor types, such as single part type, 3 part type, single point type, multi point type, rigid contact type, soft contact type, pneumatic type, silicone cup type, liquid mercury type, liquid water type, and magnetic type. The pulse probe is mainly composed of strain gauges, piezoelectric crystals, single crystal silicon, photosensitive elements, and PVDF piezoelectric films, among which single-part single-point strain gauges are most widely used, but recently, they are developing in the direction of a three-part multi-point type. However, all pulse sensors developed at home and abroad can only collect information on pulse pressure fluctuations and cannot display other multidimensional information.

In an objective study of the pulse, it was revealed that the arterial pulse includes various information such as blood vessel lumen, blood flow velocity, and three-dimensional motion of blood vessels, that is, the location, number, shape, and energy of the pulse, in addition to the information on the pressure pulse. It is difficult to fully and quantitatively reflect the component index of the pulse with a pulse pressure graph obtained using only traditional sensors such as pressure sensors.(Sometimes, multi-point pressure information is converted into a three-dimensional image, but the collection points are insufficient and the pressure information Due to the accuracy problem, the 3D reconstruction is not accurate). Therefore, the full use of 3D image acquisition technology, artificial intelligence technology, and automation control technology based on the results of the conventional automatic pulse analysis research realizes the synchronized collection of all information on the pulse such as pulse image pressure and 3D dynamic, and objectification of the oriental medicine pulse. By providing solutions for implementation, it has an important meaning in the succession of oriental medicine and promotion of innovation.

Recently, a method for acquiring pulse image 3D information based on structured light and binocular vision technology has been proposed (CN107468222A, CN1927114A), and a sensor array method has also been used, but neither of these methods can obtain sufficient accuracy, and miniaturization of technology and devices is also possible. It is difficult to implement, and there is still room for improvement in terms of acquiring pulse information, since it is not possible to achieve synchronization of 5D information in a true sense.

This utility model overcomes the shortcomings of the prior art to quickly establish a precise and accurate dynamic three-dimensional image of a pulse, and reflects minute changes in the mechanical characteristics of the pulse, temporal and spatial dimensions (five dimensions), making the computer complex. It provides a device for automatically acquiring 5D pulse information based on a kind of laser 3D scanning that can personally detect a pulse in oriental medicine.

To achieve the above object, this utility model adopts the following technical solutions.

The pneumatic control mechanism, the vertical movement control mechanism, the laser generator, the laser receiver and the central control unit are all arranged in the housing.

Further, the pneumatic control mechanism is a pneumatic pump, each intake and exhaust pipe is connected to the pneumatic pump through an independent channel, and the pneumatic pump independently controls air intake and discharge of each channel.

Further, the vertical movement control mechanism includes a hydraulic pump and an acupressure controller, and the acupressure controllers are respectively disposed in each pulse sensor. The acupressure controller includes a pulse sensor sleeve, a hydraulic piston, a piston sleeve, and a liquid inlet and discharge pipe, and the pulse sensor is installed in the pulse sensor sleeve, and the hydraulic piston is installed in the piston sleeve to provide a fixed shell of the pulse sensor. Is connected to the top of the. Both ends of the liquid inlet and discharge pipe are connected to the inside of the piston sleeve and to a hydraulic pump, respectively. Each of the liquid inlet and discharge pipes is connected to the hydraulic pump through an independent channel, and the hydraulic pump independently controls the inflow and outflow of the liquid in each channel.

Furthermore, it further includes a Jinmaek platform, wherein the Jinmaek platform is mainly composed of a forearm support and a pulse meter automatic positioner.

Determine the 3-axis position of the sensor.

The beneficial effects of this utility model are as follows.

1.Since each sensor is at least 1*1mm in traditional piezoelectric sensor arrays (PVDF piezoelectric film, etc.), the minimum precision for printing a pattern on the inner wall of a flexible hemisphere and photographing and printing with binocular visual theory is 0.5mm (exceeds this precision). If the camera cannot accurately shoot), the width of the radial artery is about 2 mm, so the data obtained by the conventional two methods of acquiring three-dimensional information on the pulse shape are not sufficiently accurate, and the points collected by the pulse cross section are also Since there are only 2-4, the 3D model cannot be reconstructed basically, and the morphological characteristics of the vein cannot be accurately reflected (the difference between the 28 types of oriental medicine bottle veins is extremely subtle). This utility model uses laser scanning technology to irradiate the scanning laser generated by the laser generator with a flexible pulsating touch film, and if the pulse fluctuates, the flexible pulsating touch film deforms according to the pulsation fluctuation, and the position of the pulse on the inner wall of the flexible pulsating touch film. As is rising to a different degree, the reflection time of the laser changes, and when the photodiode in the laser receiver receives the reflected light signal, the pulse rate according to the change of time is processed by the computer system based on the difference in the reflected time. Can form a sequence of three-dimensional images. The planar spatial resolution of the method is 0.006mm, the depth resolution reaches 0.15μm (the number of cross-sectional collection points of the pulse is up to 333), and the scanning speed is 200000 Hz, so the composed pulse dynamic three-dimensional image is precise and accurate. In addition, it can reflect subtle changes in pulses in the temporal and spatial dimensions, allowing the computer to recognize complex oriental medicine pulses.

In Jinmaek, 3 parts and 9 parts, that is, 3 times 9 parts by 3 times 3 times 3 times 3 times 9 after each part is divided into part, middle, and acupuncture by pressing the pulse with the intelligence of weak, middle, and strong, respectively. You can get information (“Difficulties, 18 columns”), and then add the comparisons between them again. The complete jinmaekji method includes: If one part is pressed with weak, medium, and strong, and the other two parts match the strength of weak, medium, and strong respectively, that is, one side is 3*3*3, resulting in a total of 27 types of paper methods, and if both sides, a total of 54 It becomes a local law. Therefore, the objectification device of pulsation must be divided into three parts and solved so that each part can press the pulsation with weak, medium, and strong intelligence.
