Description

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

The present utility model relates to the field of oriental medicine pulse automation technology, and more particularly, to a device for automatically obtaining vein 5-dimensional information based on a kind of laser 3-dimensional scanning.

The vein of oriental medicine contains a wealth of biological information, which is an important part of the four diagnostic methods. Pulsation refers to the shape of the (finger) called the pulse and refers to the shape and movement of the pulse. The formation of veins is closely related to the viscera and blood vessels. Wang Sook-hwa in Qin Dynasty summed up 24 types of pulses in the `` Minige ''. Lee Myung-jin of Ming Dynasty defined 27 veins in Vinh Ho-Kanology, and Myung-Isa Lee defined 28 veins in total, adding disease veins in Jin-Jean Proposal.

A vein element is a basic part of a vein that includes four aspects: position, number, shape, and energy. Artificial veins are recognized mainly depending on the senses of the finger. There are many types of veins, and in the Korean medical literature, the analysis is usually done from four aspects, including location, number, shape, and energy.The frequency, rhythm, site, length, width, edema of the vasculature, tension, and smooth blood flow , Heart rate strength and other factors. Once the vein elements are identified, the characteristics and formation mechanisms of the various veins can be easily understood.

Location of the Mac: The location and length of the pulse. Every time you make a diagnosis, you need to diagnose the depth and length of the area where the pulse appears. The region of normal pulse can be obtained in the middle of not rising or sinking, and the vein can be felt in 3 regions of village, tube, and chuck. If the position of the mac is shallow, it is subarrhythmic. If the position of the mac is deeply submerged, it is acupuncture. If the pulse exceeds the three parts of the chon, ducts, chuck is the bowel, if the movement of the pulse does not reach the chon, chuck is short.

Number of Macs: The number of beats and rhythms. Every time you make a diagnosis, you need to diagnose whether your pulse rate and rhythm are regular. The pulse frequency of a normal adult 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, you are fast veins, and if less than 4 times, you are veins. The pulse stops in a variety of cases, such as arrhythmia, vein, and vein. If the rhythm of the pulse is irregular, there are mountains and shovels.

Mac shape: It refers to the shape of the pulse width. Every time you make a diagnosis, you need to diagnose the size of the pulse, the shape of the softness. If the vasculature is relatively edema and the pulse width is relatively large, the erythema is small; if the pulmonary edema is small and the pulsation width is relatively small, the veins are veins; if the veins lack elasticity and softness, the veins are weak; , Veins and so on.

Aura of Mac: Refers to trends in pulse strength, softness, and more. The energy of the pulse includes several factors, such as the axial and radial strength of the pulse, the softness caused by the heart and resistive effects, and the tension caused by the vascular elasticity and tension effects. As you progress, you should diagnose the intensity and softness of your pulse. Normal pulses should be gentle, smooth, and of moderate strength. If you have strength in your Mac, you have a real vein. If the condition of the mac is relatively good and smoothly flowing, it is a live vein, and if the mac is not smooth, it is shovel.

The above is a basic element constituting the pulmonary vein, and also a basic element for diagnosing the pulmonary vein. Since the perception of the vein depends mainly on the sensation of the doctor's finger, the evolving doctor must practice the finger sensation repeatedly and carefully examine the various vein factors to obtain a relatively perfect vein and accurately distinguish the various veins. can do.

Pulses depend on the tactile function of the human fingertip. Human skin can sense various senses such as touch, pain, and heat, and the sense of touch is particularly important. Human tactile sensations are detected primarily through four tactile receptors out of a large number of mechanically stimulating receptors distributed in various depths of skin. Both the Meissner body in the epidermal skin and the fascini body in the deep skin are rapid adaptive receptors, and the former responds quickly to external stimuli in the 3-40 Hz low frequency dynamic range, enabling low frequency vibration, motion detection and grip control. . The latter responds quickly to external stimuli in the 40-500 + Hz high-frequency dynamic range, enabling sensory functions such as high-frequency vibration and tool use. In contrast, the Merkel cells, which are distributed between the epidermal basal cells throughout the body and the long spindle lupine bodies in the dermis, are slow adaptive receptors, the former being a spatial transformation, sustained in the 0.4-3.0 Hz low-frequency dynamic range. By responding slowly to external stimuli such as pressure, curves, edges, or sharp edges, it delivers sensory functions such as mode / shape detection and texture detection, while the latter is a continuous downward pressure, transverse skin with a 100-500 + Hz high frequency dynamic range. By slowly responding to external stimuli such as stretching and skin slipping, sensory functions such as finger position, stable grip, tangential force and direction of movement are realized. According to the characteristics of tactile sensing, the tactile sense can be divided into two types of sliding and flexible touch. Sliding tactile sense is a sense parallel to the finger contact surface, mainly reflects the geometry, texture, temperature, etc. of the object surface, and flexible tactile sense is a dynamic sense perpendicular to the direction of the finger contact surface, mainly reflects the flexibility or strength of the object. The density of tactile receptor distribution in each part of the human body is largely different. The 241 and 58 cm ² tactile receptors are distributed at the fingertips and palms of adults, respectively, and the difference in spatial resolution of each part of the human body is very clear. The spatial resolution of the fingertip is 0.2mm in depth perception, 0.5mm between two points, and the critical tactile response time of two events at different locations is 30-50ms. According to a controllable pressure sensitivity study, the averages of the normal pressure thresholds on the palms and fingertips of males were 0.158g and 0.055g, respectively, and the corresponding thresholds of women were 0.032g and 0.019g, respectively.

The pulse of oriental medicine is based on the sense of fingertips of the oriental medicine. Since the fingertips of human beings have the highest density of receptors, abundant and accurate information can be obtained through oriental medicine's pulsation. In order to realize the objective pulse of oriental medicine, the sensor has to reach specific indicators of human fingertip receptors in order to obtain pulse information and can accurately distinguish various pulses.

In the mid-50s of the 20th century, scientists in Chinese medicine, East-West medicine and biotechnology first led objective research in the field of oriental medicine, followed by Japanese, Korean, and US officials. Overall, the key to pulse objectification studies is the study of pulse detection sensors.

The traditional pulse detection method cannot exclude subjective factors by finger facilitation, it is not easy to record objectively and accurately, and it is difficult to inherit and innovate. Pulse detection using sensors has been widely applied in practice because it can objectively obtain the main information of the pulse, record the pulse wave signal, is easy to store and analyze, and it is easy to use without harming the human body. .

The pulse sensor was developed by Vierordt in 1860 for the first lever-type pulse recorder. In the mid 70s, interdisciplinary collaborative research teams were established one after another in domestic Tianjin, Shanghai, Yeongzhou, Jiangxi, etc., and joint researches in various fields entered the Korean medical vein research into a new stage.

There are many types of pulse detection sensors such as single part type, three part type, single point type, multi point type, rigid contact type, soft contact type, pneumatic type, silicon cup type, liquid mercury type, liquid water type, and letter type. The pulse probe is mainly composed of strain gauge, piezoelectric crystal, single crystal silicon, photosensitive element, PVDF piezoelectric film, etc. Among them, single part single point strain gauge is most widely used, but recently it has been developed in three part multi point type direction. However, current pulse sensors developed at home and abroad can only collect pulse pressure fluctuations and do not represent other multidimensional information.

In an objective study of pulsation, arterial pulses, in addition to information about pressure pulsations, included a variety of information including vessel lumen, blood flow velocity, and three-dimensional movement of blood vessels: location, number, shape, and energy of the pulse. Pulse pressure graphs obtained using traditional sensors, such as pressure sensors, are difficult to fully and quantitatively reflect the component indices of veins (sometimes converting multi-point pressure information into three-dimensional images, but there are not enough points to collect and Due to accuracy issues, the three-dimensional reconstruction is not accurate). Therefore, full utilization of 3D image acquisition technology, artificial intelligence technology, and automation control technology based on the results of conventional autopsy analysis of vein realizes full information synchronization collection of vein image pressure, 3D dynamic, etc. By providing solutions for implementation, it is important to promote the succession and innovation of oriental medicine.

Recently, a method of acquiring vein three-dimensional information based on structured light and binocular vision technology has been proposed (CN107468222A, CN1927114A), and a sensor array method has been used, but these methods cannot all be sufficiently accurate, and the technology and apparatus can be miniaturized. It is difficult to implement and there is still room for improvement because it is impossible to realize the 5D information synchronization acquisition in the real sense even in the aspect of acquiring the pulse information.

This utility model overcomes the shortcomings of the prior art and quickly establishes a precise and accurate dynamic three-dimensional image of the vein, and reflects minute changes in the mechanical characteristics of the vein, the temporal dimension and the spatial dimension (five-dimensional). The present invention provides a device for acquiring vein 5-dimensional information based on a kind of laser 3-dimensional scanning capable of trafficking an oriental medical vein.

In order to achieve the above object, the utility model adopts the following technical scheme.

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

Furthermore, the pneumatic control mechanism is a pneumatic pump, each intake and exhaust pipe is connected to the pneumatic pump through a separate channel, respectively, the pneumatic pump independently regulates the air intake and exhaust of each channel.

Furthermore, the vertical movement control mechanism includes a hydraulic pump and acupressure controller, and each acupressure sensor is disposed with the acupressure controller. The acupressure controller includes a vein sensor sleeve, a hydraulic piston, a piston sleeve and a liquid inlet and outlet pipe, the vein sensor is installed in the vein sensor sleeve, and the hydraulic piston is installed in the piston sleeve to fix the shell of the vein sensor. Is connected to the top of the. Both ends of the liquid inlet and outlet pipe are connected to the inner and hydraulic pumps of the piston sleeve, respectively.

Determine the 3-axis position of the sensor.

The beneficial effects of this utility model are as follows.

1.In traditional piezoelectric sensor arrays (PVDF piezoelectric film, etc.), each sensor is at least 1 * 1mm, so the minimum precision of printing a pattern on a flexible hemisphere inner wall and shooting with binocular vision theory is 0.5mm (exceeding this precision). Because the width of the radial artery is about 2 mm, the data obtained by the conventional two methods of acquiring three-dimensional information of the pulse are not accurate enough, and the points collected by the pulse cross section are not accurate. Because there are only two or four, three-dimensional models cannot be reconstructed fundamentally and cannot accurately reflect the morphological characteristics of the veins (the differences between 28 oriental vein types are extremely subtle). This utility model uses laser scanning technology to irradiate the scanning laser generated by the laser generator with the flexible pulse touch film, and if the pulse fluctuates, the flexible pulse touch film deforms according to the pulse fluctuation, and the inner wall pulse position of the flexible pulse touch film Rises to a different degree, the laser's reflection time is changed, and when the photodiode in the laser receiver receives the reflected light signal, it is processed by the computer system based on the difference in the reflected time and the pulse according to the change of time It can form a three-dimensional image sequence of.

It becomes a local law. Therefore, the pulsed objectification device must be divided into three parts, and each side must be able to press the pulse with weak, medium, and strong forcing.

When S3 and pulse fluctuate, the flexible pulse touch film deforms along the pulse, and as the inner wall pulse position of the flexible pulse touch film rises to a different degree, the reflection time of the laser is changed, and the photodiode in the laser receiver reflects the reflected light signal. Received by the computer system, based on the difference in the reflected time is processed by the computer system to form a three-dimensional image sequence of the pulse according to the change of time, then the computer system combines the pressure data corresponding to the time point Five-dimensional information data of the vein including information, pressure information, and three-dimensional image information is formed, and recognition and analysis of the vein information is performed.

After the recognition, the position of the village, the tube and the vertebrae are determined, and the three-axis platform is controlled to automatically move the three vein sensors to the region of the wrist, the tube and the vertebral vein. When the flexible pulse touch film of the pulse sensor touches the skin, the pressure in the closed chamber changes, and the pressure sensor transmits the measured pressure data in real time to the central controller. The central controller transmits the pressure to the computer system. (I.e. fluctuation in pulse rate) is detected, the positioning is completed.

Specifically, as the computer system recognizes the position of the styloid process of radius through a photograph of the wrist to determine the position of the vein, the oriental medical scriptures show that "the palmar bone is above the tube and the front of the tube is positive, The back of the tube is umbilical, and the position of the veins can be accurately determined based on the vein positioning method of sequential finding of the Yangchon chuck.

It is necessary to explain that, in step S2, a specific process of moving the three pulse sensors up and down by the vertical movement control mechanism is as follows.
