Description

Technical Field

[0001] The invention relates to a pulse replay device, in particular to a traditional Chinese medicine three-part nine-part pulse replay device and a replay method. Background Art

[0002] Traditional Chinese medicine is the crystallization of thousands of years of wisdom of the Chinese nation. "Looking, smelling, asking, and palpating" are the most common and unique diagnostic methods of traditional Chinese medicine. Pulse diagnosis belongs to "palpating" and is the most characteristic of traditional Chinese medicine. It is often regarded as a microcosm of traditional Chinese medicine clinical practice, and even a synonym for traditional Chinese medicine. The pulse can reflect the physiological and pathological conditions of the human body. It is an important window for observing the functional changes of internal organs in the human body. It is of great significance in identifying symptoms, judging the condition, distinguishing the pathogenesis, and inferring the prognosis. The three parts and nine signs are one of the oldest pulse diagnosis methods in my country. It was first seen in "The Yellow Emperor's Classic of Internal Medicine·Su Wen". The Cunkou diagnosis method is a common three-part nine-sign diagnosis method in clinical practice of traditional Chinese medicine. The Cunkou position is superficial and the pulse fluctuation is easy to feel. The Cunkou pulse is divided into three parts: Cun, Guan, and Chi. Each part is divided into light, medium, and heavy pulse pressure to take the pulse, which is divided into floating, medium, and sinking signs, collectively known as "three parts and nine signs".

[0003] Remote TCM diagnosis technology refers to a technical means of remotely conducting TCM diagnosis through the Internet and communication technology, so that doctors can perform TCM diagnosis on patients without direct contact with patients. Remote TCM diagnosis technology can break through geographical restrictions, integrate high-quality medical resources, and improve the accessibility and efficiency of medical services. It is of great significance to alleviate the uneven distribution of medical resources and solve the problem of "difficulty in seeing a doctor" for patients in remote areas. The replay of the pulse image of the three parts and nine hou of TCM is the key technology to realize remote TCM diagnosis.

[0004] The pulse of traditional Chinese medicine contains four attributes: "position, number, shape, and momentum", among which "position" refers to the "floating, middle, and sinking" of the pulse position; "number" refers to the frequency and rhythm of the pulse; "shape" refers to the shape of the blood vessel itself in a static state; and "momentum" refers to the trend of the pulse pulsation. The two attributes of "number" and "momentum" can be restored by simulating and reproducing the pulse pulsation, but the finger feeling of the Chinese medicine practitioner for the pulse is three-dimensional. For the same pulse waveform, the filling degree of the blood vessels is different, the blood pressure is different, and the finger feeling is completely different. It is difficult to simulate and reproduce the pulse without liquid pulsation (such as the Pi pulse). At the same time, the existing pulse simulation and reproduction devices cannot reproduce the pulse of Cun Shang, Cun, Guan, Chi, and Cun Xia on the same flowing tube, nor can they reproduce the opposite pulses of two adjacent parts, such as Cun for sinking pulse and Guan for floating pulse. Only by comprehensively considering the four elements of pulse image, namely "position, number, shape and strength" for playback can the complete information unique to clinical pulse image be correctly restored. This has become an urgent problem to be solved in traditional Chinese medicine pulse image playback technology.

[0005] The invention patent application with application number 201710732393.9 discloses a pulse diagnosis device that accurately simulates the process of Chinese medicine pulse diagnosis, which is composed of a low-power control circuit, a pulse detection sensor, a sensor positioning device, a common pressure sensor, a data sampling and transmission circuit, a temperature sensor, a shell device, a personal information collection module, an instruction issuing device, a data receiving module, a data analysis and diagnosis module, a database, etc. It realizes the precise control of pulse diagnosis, can better promote the quantification of Chinese medicine diagnostic indicators and the standardization of diagnostic results, can realize pulse diagnosis anytime and anywhere, and can better promote the process of Chinese medicine pulse diagnosis.

[0006] The utility model patent with application number 201120547014.7 discloses a pulse information acquisition system, which is mainly composed of three pulse sensors, a controller, a memory, a display, a power supply, etc. The controller includes an A / D conversion circuit, and the three pulse sensors are connected to the analog signal input interface of the A / D conversion circuit of the controller through a sensor interface circuit; the display signal output interface of the controller is connected to the signal input interface of the display. The system is a pulse signal acquisition system based on a piezoresistive sensor, which eliminates the subjective feeling judgment factor in traditional Chinese medicine palpation; a method for automatically adjusting the pulse pressure is proposed to improve the effectiveness of pulse signal acquisition.

[0007] The utility model with application number 202022020748.1 discloses a pulse recording detection device, comprising a pulse detection device (1) and a pulse display terminal (2), wherein the pulse detection device (1) is electrically connected to the pulse display terminal (2), and the pulse detection device (1) is configured to detect pulse pulsation pressure, generate a pulse fluctuation signal, and convert the pulse pulsation signal into a digital signal and transmit it to the pulse display terminal (2), so that the pulse pulsation signal can be shown in the form of an image by the pulse display terminal (2), and the pulse display terminal (2) is configured with a memory so that the digital signal can be stored by the memory. The utility model can convert pulse fluctuations into image information and store it, so that pulse detection is digitized, which is conducive to adapting to the new development of mobile medical care and is also conducive to the promotion of traditional Chinese medicine pulse.

[0008] To realize remote TCM diagnosis and share medical resources, it is necessary to comprehensively consider the four elements of pulse: position, number, shape, and potential. Only through replay can the complete information unique to clinical pulse be correctly restored. Obviously, the existing technology is far from enough in the research of TCM pulse replay technology, which needs to be solved urgently. The pulse pulsation generation device is the core component of the TCM three-part nine-part pulse replay device, which determines whether the three-part nine-part pulse can be accurately replayed. Summary of the invention

[0009] In order to solve the problem of accurate playback and restoration of the four attributes of "position, number, shape and potential" of the three-part and nine-hou pulse in traditional Chinese medicine, the present invention innovatively designs a method and an implementation device for replaying the three-part and nine-hou pulse in traditional Chinese medicine from the perspective of bionics and engineering, combined with multi-sensor information fusion technology, which can be used for remote traditional Chinese medicine pulse diagnosis and traditional Chinese medicine pulse teaching evaluation.

[0010] The technical solution adopted by the present invention is:

[0011] The device of the present invention is composed of a main control unit ( Figure 1 The module is composed of a main control module in the apparatus, a pulse generating device, a simulated hand and inch, guan and chi pressure detecting module, a liquid pipeline pressure monitoring and feedback control module, and a simulated blood reservoir. Each module is connected by a simulated blood vessel, and simulated blood flows in the simulated blood vessel.

[0012] The pulse pulsation generating device is the core component of the pulse image replaying device of the three parts of traditional Chinese medicine, and is composed of a liquid circuit interface, a bellows upper plug, a fixed platform, a bellows, a bellows lower plug, an oscillator, and a fixed base. The bellows is composed of an elastic tube body, a liquid storage cavity, an upper plug, and a lower plug. The elastic tube body simulates the contraction and relaxation of heart muscles and drives the simulated blood flow in the liquid storage cavity; the bellows upper plug is fixed on the fastening platform and is connected to the simulated blood vessel through the liquid circuit interface; the bellows lower plug is fixed to the oscillator through a connecting rod. The oscillator causes the vibration head to produce different displacements according to the change in the strength of the control current. The vibration head is connected to the connecting rod. The reciprocating movement of the vibration head up and down drives the contraction and relaxation of the bellows elastic cavity, thereby causing the liquid storage cavity to contract or relax, discharge or inhale the simulated blood into the liquid storage cavity, drive the simulated blood to flow in the simulated blood vessel, and produce corresponding expansion and contraction at the simulated blood vessel, thereby forming a perceptible pulse pulsation.

[0013] The simulated hand and Cun, Guan, Chi pressure detection module are made by using bionics to sample and produce the simulated hand of an adult man as a template, simulating the structure and finger feeling of the palm and arm of an adult, and are composed of a silicone hand and hand skin, an injection molded arm, and are embedded with simulated blood vessels. There is a bulge on the front side of the injection molded arm to simulate the radial styloid process to facilitate the positioning of the Guan position. The Cun, Guan, Chi pressure detection module is composed of a Cun, Guan, Chi pressure detection board, a pressure sensor, and a latex module. Five pressure sensors can be placed on the Cun, Guan, Chi pressure detection board to detect the pulse pressure of five sites: Cun Shang, Cun, Guan, Chi, and Chi Xia; there is a simulated blood vessel placement groove on the latex module, and the simulated blood vessel is placed in the groove to restore the relationship between the blood vessel and the peripheral tissue. There are four grooves under the latex module, which divide the latex module into five small modules, and each small module corresponds to a sensor position, so as to prevent interference with the pressure detection of adjacent sites after pressing at one site when taking the pulse.

[0014] The liquid pipeline pressure detection and feedback control module is composed of a liquid pipeline pressure detection sensor, a liquid pipeline control valve 1, a liquid pipeline control valve 2 and a hydraulic control pump. The liquid volume in the simulated blood vessel and the filling degree of the simulated blood vessel are changed by controlling the actions of the liquid pipeline control valve 1, the liquid pipeline control valve 2 and the hydraulic control pump, thereby simulating the compliance of the blood vessel and restoring the static shape of the blood vessel. In this process, the liquid pipeline pressure detection sensor detects the pressure in the simulated blood vessel in real time.

[0015] The simulated blood storage container is a closed, transparent container, which is mainly used to store simulated blood. The main component of simulated blood is sodium carboxymethyl cellulose, which is a food-grade thickener, safe and harmless, does not react with silica gel and can be stored for a long time. The viscosity will increase after adding water, and after adding red dye, simulated blood of different viscosities can be prepared. At the same time, an appropriate amount of alcohol is added to the sodium carboxymethyl cellulose solution to lower the freezing point of the solution and prevent the solution from freezing at low temperatures.

[0016] The "number" and "force" attributes of the pulse are achieved by simulating heart beats through a pulse pulsation generating device, driving simulated blood to flow in a simulated vascular system; the "position" attribute of the pulse is achieved by real-time detection of the pulse pressure and position through the Cun, Guan, and Chi pressure detection module under the simulated hand radius position, and the pulse pulsation generating device generates corresponding pulse pulsations based on the pulse pressure and position; the "shape" attribute of the pulse is achieved by real-time detection of the "blood pressure" in the simulated vascular system through a liquid pipeline pressure monitoring and feedback control module, and the simulated vascular morphology is changed by adjusting the vascular filling degree by controlling the liquid control valve, hydraulic control pump, etc.

[0017] This invention comprehensively considers the four attributes of pulse, namely "position, number, shape and potential", for playback, truly realizing the complete restoration of clinical pulse information and laying a solid foundation for the realization of remote Chinese medicine pulse diagnosis.

[0018] The present invention has the advantages and beneficial positive effects:

[0019] 1. The present invention innovatively designs a pulse playback device for three parts and nine lords of traditional Chinese medicine from the perspective of bionics and engineering, combined with multi-sensor information fusion technology, and comprehensively considers the four attributes of pulse "position, number, shape, and potential" for playback, truly realizing the complete restoration of clinical pulse information, and laying a solid foundation for the realization of remote traditional Chinese medicine pulse diagnosis. The pulse "number" and "potential" attributes are realized by simulating heart beats and driving simulated blood to flow in the simulated vascular system through the pulse pulsation generation device; the pulse "position" attribute is realized by real-time detection of pulse pressure and pulse position by the Cun, Guan, and Chi pressure detection module under the simulated hand radius position, and the pulse pulsation generation device generates corresponding pulse pulsations according to the pulse pressure and pulse position; the pulse "shape" attribute is realized by real-time detection of "blood pressure" in the simulated vascular system through the liquid pipeline pressure monitoring and feedback control module, and the simulated vascular morphology is changed by adjusting the vascular filling degree by controlling the liquid control valve, hydraulic control pump, etc.

[0020] 2. The present invention comprehensively considers the four attributes of "position, number, shape, and potential" of the pulse to reproduce, truly realizes the complete restoration and reproduction of clinical pulse information, and can be used for remote Chinese medicine pulse diagnosis and Chinese medicine pulse diagnosis teaching evaluation. In addition, the device of the present invention can carry out research on the influence of vascular elasticity on the pulse by replacing the simulated blood vessels with different elastic coefficients, and further carry out arteriosclerosis related research work with this. By allocating simulated blood with different viscosities, research on the influence of different viscosities of blood such as hyperlipidemia and hyperglycemia on the pulse can be carried out, and by changing the simulated blood vessel initialization pressure, research on the influence of different blood pressures such as hypertension on the pulse can be carried out, and further carry out blood system, blood system diseases, chronic disease Chinese medicine diagnosis research, integrated Chinese and Western medicine research, etc. with this.

[0021] 3. The pulse playback device of the Three-Part Nine-Hou of Traditional Chinese Medicine of the present invention comprises a bellows composed of an elastic tube body that simulates the contraction and relaxation of heart muscles, driving the simulated blood flow in the liquid storage chamber; the oscillator causes the vibration head to produce different displacements according to the change in the strength of the control current, and the vibration head is connected to the connecting rod. The up and down reciprocating motion of the vibration head drives the contraction and relaxation of the elastic cavity of the bellows, thereby causing the liquid storage chamber to contract or relax, discharge or inhale the simulated blood into the liquid storage chamber, drive the simulated blood to flow in the simulated blood vessels, and produce corresponding expansion and contraction at the simulated blood vessels, thereby forming a perceptible pulse pulsation.

[0022] 4. The pulse playback device of the three parts and nine hou of traditional Chinese medicine of the present invention fixes the oscillator 14, the bellows 12, etc. together by fastening the platform 11 and the fixed base 15, which limits the elastic cavity of the bellows to only contraction or relaxation movement, thereby reducing the pulse playback error, reducing noise and vibration, and improving the stability and reliability of the pulse playback device of the three parts and nine hou.

[0023] 5. The pulse image replay device of the three parts and nine lords of traditional Chinese medicine of the present invention can be placed on the Cun, Guan, Chi pressure detection board with 5 pressure sensors to detect the pulse pressure of the five sites of Cun Shang, Cun, Guan, Chi, and Chi Xia to restore the relationship between blood vessels and peripheral tissues; there is a simulated blood vessel placement groove on the latex module, and the simulated blood vessel is placed in the groove to restore the relationship between blood vessels and peripheral tissues. There are 4 grooves under the latex module, and the latex module is divided into 5 small modules. A sensor is set at each small module position to prevent interference with the pressure detection of adjacent sites after pressing at one site during pulse taking. The simulated blood vessel is made of silicone tube, and the thickness and elasticity are consistent with the blood vessels of normal adult men, so as to more accurately replay the pulse information.

[0031] Example 1

[0032] See also Figure 1 The present invention provides a pulse image playback device for three parts of traditional Chinese medicine, which is composed of a main control unit (main control module in the figure), a pulse pulsation generating device, a simulated hand and cunguanchi pressure detection module, a fluid pipeline pressure monitoring and feedback control module, and a simulated blood reservoir. The modules are connected through simulated blood vessels, and simulated blood flows in the simulated blood vessels; wherein, Figure 2 As shown, the pulse pulsation generating device includes a simulated vessel 3, a simulated blood vessel 4 and a heart contraction and relaxation simulation mechanism, the simulated vessel 3 is arranged in the simulated blood vessel 4 circuit, and the heart contraction and relaxation simulation mechanism includes a bellows 12 and an oscillator 14; the bellows 12 is composed of an elastic tube body, a liquid storage chamber, an upper plug 10, and a lower plug 13, the bellows upper plug 10 is fixed on a fastening platform 11, and is connected to the simulated blood vessel 4 through a liquid circuit interface 9; the bellows lower plug 13 is fixed to the oscillator 14 through a connecting rod; the oscillator 14 is controllably connected to the main control unit.

[0033] The bellows consists of an elastic tube body that simulates the contraction and relaxation of heart muscles, driving the simulated blood flow in the liquid storage cavity; the oscillator causes the vibration head to produce different displacements according to the change in the strength of the control current. The vibration head is connected to the connecting rod.

The oscillator 14, the bellows 12, etc. are fixed together through the fastening platform 11 and the fixed base 15, which limits the bellows elastic cavity to only contraction or diastole movement, reduces the pulse image replay error, reduces noise and vibration, and improves the stability and reliability of the three-part nine-hou pulse image replay device.

[0036] Example 3

[0037] The Traditional Chinese Medicine Three-Part Nine-Hou Pulse Image Replay Device of this embodiment is different from that of Embodiment 1 or Embodiment 2 in that the simulated hand 1 is composed of a silicone hand and hand skin, and an injection-molded arm, with simulated blood vessels embedded therein. There is a protrusion on the front side of the injection-molded arm to simulate the radial styloid process to facilitate the positioning of the Guan position; the wrist of the simulated hand 1 and the simulated blood vessels 3 are cooperated to set the Cun, Guan, and Chi pressure detection module 2, and the pressure sensor output signal of the Cun, Guan, and Chi pressure detection module 2 is connected to the main control unit.

[0038] The simulated hand 1 and the Cun, Guan, and Chi pressure detection module 2 are manufactured using bionics with an adult male's hand as a template to simulate the structure and finger feel of an adult's palm and arm, with simulated blood vessels embedded inside and a bulge on the side of the front end of the injection-molded arm to simulate the radial styloid process for easy positioning of the joint.

[0039] Example 4

[0040] See also Figure 3 The Traditional Chinese Medicine Three-Part Nine-Hou Pulse Image Replay Device of this embodiment is different from the aforementioned embodiments in that the Cun, Guan, Chi pressure detection module 2 is composed of a Cun, Guan, Chi pressure detection plate 20, a pressure sensor 19 and a latex module 17; a simulated vessel placement groove 18 is provided on the latex module 17, and a simulated vessel 3 connected to a simulated blood vessel 4 is placed in the simulated vessel placement groove 18, and four grooves are provided under the latex module 17, dividing the latex module into five small modules, and a pressure sensor is correspondingly arranged at each small module position; the output signal of the pressure sensor is connected to the main control unit.

[0041] like Figure 3 As shown, 5 pressure sensors are placed on the Cun, Guan, Chi pressure detection plate 20, which are used to detect the pulse pressure at the 5 sites of Cun Shang, Cun, Guan, Chi, and Chi Xia respectively; the simulated blood vessels are placed in the simulated blood vessel placement groove 18 on the latex module 17 to restore the relationship between blood vessels and peripheral tissues. The 4 grooves below the latex module divide the latex module into 5 small modules, and a sensor is correspondingly arranged at each small module position to prevent interference with the pressure detection of adjacent sites after pressing at one site during pulse taking. The simulated blood vessels are made of silicone tubes, and the thickness and elasticity are consistent with the blood vessels of normal adult men, so as to more accurately reproduce the pulse information.

[0042] Example 5

[0043] See also Figure 1-Figure 3 The TCM three-part nine-hou pulse image replay device of this embodiment is different from the above-mentioned embodiments in that the fluid pipeline pressure detection and feedback control module is composed of a fluid pipeline pressure detection sensor 5, a fluid pipeline control valve I6, a fluid pipeline control valve II8, a hydraulic control pump 7 and a simulated blood reservoir 16. The fluid pipeline pressure detection sensor 5 is connected to the simulated blood vessel 4; the fluid pipeline control valve I6 is arranged in the simulated blood vessel 4 circuit at the outlet of the hydraulic control pump 7, and the fluid pipeline control valve II8 is arranged in the pipeline from the simulated blood vessel 4 to the blood reservoir 16; the fluid inlet of the hydraulic control pump 7 is arranged in the simulated blood reservoir 16. The control fluid pipeline control valve I, the fluid pipeline control valve II and the hydraulic control pump 7 are controlled and connected to the main control unit; the output signal of the fluid pipeline pressure detection sensor 5 is connected to the main control unit.

[0044] The main control unit changes the liquid volume in the simulated blood vessel and the filling degree of the simulated blood vessel by controlling the actions of the liquid circuit control valve I, the liquid circuit control valve II and the hydraulic control pump 7, thereby simulating the compliance of the blood vessel and restoring the static state of the blood vessel. In this process, the liquid circuit pipeline pressure detection sensor 5 detects the pressure in the simulated blood vessel 4 in real time. The liquid circuit control valve I is opened, the liquid circuit control valve II is closed, and the hydraulic control pump 7 is rotated forward to drive the simulated blood pressure in the simulated blood reservoir to enter the simulated blood vessel system, and the pressure in the simulated blood vessel increases, causing the simulated blood vessel to expand and the filling degree of the blood vessel to increase; the liquid circuit control valve I is opened, the liquid circuit control valve II is closed, and the hydraulic control pump 7 is rotated in the reverse direction to drive the simulated blood in the simulated blood vessel to flow back to the simulated blood reservoir 16, and the pressure in the simulated blood vessel decreases, causing the simulated blood vessel to contract and the filling degree of the blood vessel to decrease. At the same time, open liquid circuit control valve I and liquid circuit control valve II, rotate the hydraulic control pump forward, drive the simulated blood pressure in the simulated blood reservoir to flow in the simulated blood vessel, and discharge the bubbles in the simulated blood vessel system; this working mode can also realize the replacement of simulated blood in the simulated blood vessel system, so as to carry out research on the influence of changes in blood viscosity on pulse.

[0045] In the TCM three-part nine-hou pulse image playback device of the present invention, the simulated blood storage container 16 is a closed, transparent container, which is mainly used to store simulated blood. The main component of the simulated blood is sodium carboxymethyl cellulose, which is a food-grade thickener, safe and harmless, does not react with silica gel and can be stored for a long time. The viscosity will increase after adding water, and after adding red dye, simulated blood of different viscosities can be prepared. At the same time, an appropriate amount of alcohol is added to the sodium carboxymethyl cellulose solution to lower the freezing point of the solution and prevent the solution from freezing at low temperatures.

[0046] Example 6

[0047] A method for replaying the pulse image of three parts and nine hou in traditional Chinese medicine is realized by using the pulse image replay device as described above: a pulse pulsation generating device is used to simulate heart pulsation and drive simulated blood to flow in a simulated blood vessel system to realize the replay of the pulse image of "number" and "force" attributes of traditional Chinese medicine pulse image; a cun, guan, and chi pressure detection module under the simulated hand radius position is used to detect the pulse pressure and pulse position in real time, and the pulse pulsation generating device generates corresponding pulse pulsation according to the pulse pressure and pulse position to realize the replay of the pulse image of "position" attribute of traditional Chinese medicine pulse image; a liquid pipeline pressure monitoring and feedback control module is used to detect the "blood pressure" in the simulated blood vessel system in real time, and the simulated blood vessel morphology is changed by controlling the liquid control valve and the hydraulic control pump to adjust the blood vessel filling degree to realize the replay of the pulse image of "shape" attribute of traditional Chinese medicine pulse image.

[0048] Example 7

[0049] See also Figure 4The difference between the TCM three-part nine-hou pulse playback method of this embodiment and that of Embodiment 6 is that: further, the process of implementing pulse playback through the pulse playback device is as follows:

[0050] After the device is started, the system self-check is first performed, mainly to check whether the pulse pulsation generating device, Cunguanchi pressure detection module, liquid pipeline pressure detection and feedback control module can work normally and whether there is leakage;

[0051] After the self-check is completed, the main control module (main control unit) of the device receives the re-released pulse data, controls the pressure detection and feedback control module of the fluid pipeline to adjust the "blood pressure" in the simulated blood vessel to the "static pressure value" of the re-released pulse data, and controls the pulse pulsation generating device to work after the simulated blood vessel reaches the "static pressure value" to re-release the pulse at the simulated hand Cun Guan Chi position;

[0052] At the same time, the main control module receives the pulse position and pulse pressure detected by the Cun, Guan, and Chi pressure detection modules in real time, and extracts the corresponding pulse data segment in the reproduced pulse data according to the pulse position and pulse pressure, controls the operation of the pulse pulsation generating device, and reproduces the pulse at the simulated hand Cun, Guan, and Chi positions, and repeats this process until the main control module detects that the pulse position and pulse pressure have not changed, and the device automatically determines that the reproduction is completed, the device starts to initialize, the bellows in the pulse pulsation generating device returns to normal, the simulated blood vessel pressure returns to the predetermined initial value, and the system waits for the next pulse data segment to be reproduced.

[0053] During the release process, the liquid pipeline pressure detection and feedback control module always monitors the pressure changes in the liquid circuit in real time. When the pressure in the liquid circuit exceeds or is lower than 25% of the "static pressure value" of the release pulse, the release device will shut down automatically and alarm at the same time to prevent pipe burst and leakage.

[0054] Example 8

[0055] See also Figure 5The method for replaying the pulse of the three parts and nine hou of traditional Chinese medicine in this embodiment is different from that in embodiment 7 in that: further, the self-test process of the device is as follows: after the self-test of the device starts, firstly, it is determined whether the pressure sensor in the Cun, Guan, and Chi pressure detection module can detect data. Because the pressure sensor is under the latex module, it has a certain pressure value. After the pressure data is detected, the detected pressure data is "reset to zero"; secondly, it is determined whether the liquid pipeline pressure detection sensor can detect data. After the pressure value is detected, the main control module controls the liquid pipeline pressure detection and feedback control module to "pressurize" and "depressurize" the simulated blood vessel to determine whether the device can pressurize and depressurize normally; thirdly, the liquid control valve I and the liquid control valve II are opened at the same time. The liquid circuit control valve II and the hydraulic control pump drive and control the simulated blood pressure to flow in the simulated blood vessel and the simulated blood reservoir. If there are bubbles in the simulated blood vessel, the bubbles in the simulated blood vessel can be removed to ensure accurate pulse playback; again, close the liquid circuit control valve I, the liquid circuit control valve II and the hydraulic control pump, and the main control module drives and controls the bellows in the pulse pulsation generating device to move back and forth regularly, and checks in real time whether the pressure in the simulated blood vessel detected by the liquid circuit pipeline pressure detection sensor changes regularly, so as to judge whether the pulse pulsation generating device is working normally; finally, the device starts to initialize, the bellows in the pulse pulsation generating device returns to normal state, the pressure in the simulated blood vessel returns to the preset pressure, and the system plays back the pulse data.

[0056] Example 9

[0057] The present invention is a three-part and nine-part pulse image playback device of traditional Chinese medicine, and the system block diagram is as follows Figure 1 As shown in the structural diagram Figure 2 As shown, it is composed of a main control module, a pulse pulsation generating device, a simulated hand and Cun, Guan, and Chi pressure detection module, a fluid pipeline pressure monitoring and feedback control module, and a simulated blood storage device. Each module is connected by a simulated blood vessel, and simulated blood flows in the simulated blood vessel. The pulse "number" and "potential" attributes are reproduced by simulating heart beats and driving simulated blood to flow in the simulated vascular system through the pulse pulsation generating device; the pulse "position" attribute is detected by the Cun, Guan, and Chi pressure detection module under the radial position of the simulated hand in real time, and the pulse pulsation generating device generates corresponding pulse pulsations according to the pulse pressure and pulse position; the pulse "shape" attribute is detected by the fluid pipeline pressure monitoring and feedback control module in real time in the simulated vascular system, and the simulated vascular morphology is changed by controlling the fluid control valve, hydraulic control pump, etc. to adjust the vascular filling degree. The invention comprehensively considers the four attributes of "position, number, shape, and potential" of the pulse to reproduce, truly realizing the complete restoration of clinical pulse information, and laying a solid foundation for the realization of remote Chinese medicine pulse diagnosis.

[0058] The pulse pulsation generating device is the core component of the TCM three-part nine-hou pulse image playback device, which determines whether the three-part nine-hou pulse image can be accurately played back. The device is composed of a liquid path interface 9, a bellows upper plug 10, a fixed platform 11, a bellows 12, a bellows lower plug 13, an oscillator 14, and a fixed base 15.

[0059] The bellows is composed of an elastic tube body, a liquid storage cavity, an upper plug 10, and a lower plug 13. The elastic tube body simulates the contraction and relaxation of the heart muscle and drives the simulated blood flow in the liquid storage cavity. The upper plug 10 of the bellows is fixed on the fastening platform and is connected to the simulated blood vessel 4 through the liquid path interface 9. The lower plug 13 of the bellows is fixed to the oscillator 14 through a connecting rod. The oscillator causes the vibration head to produce different displacements according to the change of the strength of the control current. The vibration head is connected to the connecting rod. The reciprocating up and down movement of the vibration head drives the contraction and relaxation of the elastic cavity of the bellows, thereby causing the liquid storage cavity to contract or relax, discharge or inhale the simulated blood into the liquid storage cavity, drive the simulated blood to flow in the simulated blood vessel, and produce corresponding expansion and contraction at the simulated blood vessel, thereby forming a perceptible pulse pulsation.

[0060] At the same time, the oscillator 14, the bellows 12, etc. are fixed together by using the fastening platform 11 and the fixed base 15, which limits the bellows elastic cavity to only contraction or relaxation movement, thereby reducing the pulse playback error, reducing noise and vibration, and improving the stability and reliability of the Sanbu Jiuhou pulse playback device.

[0061] Among them, the simulated hand 1 and the Cun, Guan, and Chi pressure detection module 2 are made by using bionics to sample and sample an adult man's hand as a template, simulating the structure and finger feel of an adult's palm and arm. It is composed of a silicone hand and hand skin, and an injection-molded arm, with simulated blood vessels embedded inside. There is a bulge on the front side of the injection-molded arm to simulate the radial styloid process to facilitate the positioning of the joint.

[0062] The structure of the Cunguanchi pressure detection module 2 is as follows Figure 3 As shown, it is composed of a Cun-Guan-Chi pressure detection plate 20, a pressure sensor 19 and a latex module 17. Five pressure sensors can be placed on the Cun-Guan-Chi pressure detection plate 20 to detect the pulse pressure at five sites: Cun-Shang, Cun-Guan, Chi and Chi-Xia. There is a simulated blood vessel placement groove 18 on the latex module 17, and the simulated blood vessel is placed in the groove to restore the relationship between the blood vessel and the peripheral tissue. There are four grooves under the latex module, and the latex module is divided into five small modules. A sensor is correspondingly set at each small module position to prevent interference with the pressure detection of adjacent sites after pressing at one site during pulse taking. The simulated blood vessel is made of silicone tube, and the thickness and elasticity are consistent with the blood vessels of normal adult men, so as to more accurately reproduce the pulse information.

[0063] The fluid pipeline pressure detection and feedback control module is composed of a fluid pipeline pressure detection sensor 5, a fluid control valve I, a fluid control valve II and a hydraulic control pump 7. The fluid volume in the simulated blood vessel is changed by controlling the actions of the fluid control valve I, the fluid control valve II and the hydraulic control pump 7, so as to change the simulated blood vessel filling degree, thereby simulating the compliance of the blood vessel and restoring the static state of the blood vessel. In this process, the fluid pipeline pressure detection sensor 5 detects the pressure in the simulated blood vessel 4 in real time. The fluid control valve I is opened, the fluid control valve II is closed, and the hydraulic control pump 7 is rotated forward to drive the simulated blood pressure in the simulated blood reservoir to enter the simulated blood vessel system, and the pressure in the simulated blood vessel increases, causing the simulated blood vessel to expand and the blood vessel filling degree to increase; the fluid control valve I is opened, the fluid control valve II is closed, and the hydraulic control pump 7 is rotated backward to drive the simulated blood in the simulated blood vessel to flow back to the simulated blood reservoir 16, and the pressure in the simulated blood vessel decreases, causing the simulated blood vessel to contract and the blood vessel filling degree to decrease. At the same time, open liquid circuit control valve I and liquid circuit control valve II, rotate the hydraulic control pump forward, drive the simulated blood pressure in the simulated blood reservoir to flow in the simulated blood vessel, and discharge the bubbles in the simulated blood vessel system; this working mode can also realize the replacement of simulated blood in the simulated blood vessel system, so as to carry out research on the influence of changes in blood viscosity on pulse.

[0064] The simulated blood storage tank is used to store simulated blood. The main component of simulated blood is sodium carboxymethyl cellulose. By adding water and red dye, simulated blood of different viscosities can be prepared. At the same time, an appropriate amount of alcohol is added to the sodium carboxymethyl cellulose solution to lower the freezing point of the solution and prevent the solution from freezing at low temperatures.

[0065] The pulse replay process of the device of the present invention is as follows Figure 4 As shown, after the device is started, the system self-check is first performed, mainly to check whether the pulse pulsation generating device, the Cun, Guan, and Chi pressure detection module, and the fluid pipeline pressure detection and feedback control module can work normally, whether there is leakage, etc. After the self-check is completed, the main control module of the device receives the re-released pulse data, controls the fluid pipeline pressure detection and feedback control module to adjust the "blood pressure" in the simulated blood vessel to the "static pressure value" of the re-released pulse data, and controls the pulse pulsation generating device to work after the simulated blood vessel reaches the "static pressure value", and re-releases the pulse at the Cun, Guan, and Chi positions of the simulated hands.

[0066] At the same time, the main control module receives the pulse position and pulse pressure detected by the Cun, Guan, and Chi pressure detection modules in real time, and extracts the corresponding pulse data segment in the reproduced pulse data according to the pulse position and pulse pressure, controls the operation of the pulse pulsation generating device, and reproduces the pulse at the simulated hand Cun, Guan, and Chi positions, and repeats this process until the main control module detects that the pulse position and pulse pressure have not changed, and the device automatically determines that the reproduction is completed, the device starts to initialize, the bellows in the pulse pulsation generating device returns to normal, the simulated blood vessel pressure returns to the predetermined initial value, and the system waits for the next pulse data segment to be reproduced.

[0067] During the release process, the liquid pipeline pressure detection and feedback control module always monitors the pressure changes in the liquid circuit in real time. When the pressure in the liquid circuit exceeds or is lower than 25% of the "static pressure value" of the release pulse, the release device will shut down automatically and alarm at the same time to prevent pipe burst and leakage.

[0068] The self-checking process of the device of the present invention is as follows Figure 5 As shown, after the self-test of the device starts, it first determines whether the pressure sensor in the Cun Guan Chi pressure detection module can detect data. Because the pressure sensor is under the latex module and has a certain pressure value, the detected pressure data will be "reset to zero" after the pressure data is detected; secondly, it determines whether the liquid pipeline pressure detection sensor can detect data. After the pressure value is detected, the main control module controls the liquid pipeline pressure detection and feedback control module to "pressurize" and "depressurize" the simulated blood vessel to determine whether the device can pressurize and depressurize normally; thirdly, open the liquid circuit control valve I, liquid circuit control valve II and the hydraulic control pump at the same time to drive and control the simulated blood pressure in the simulation. The blood flows in the simulated blood vessel and the simulated blood reservoir. If there are bubbles in the simulated blood vessel, the bubbles in the simulated blood vessel can be removed to ensure accurate pulse playback; again, close the liquid circuit control valve I, liquid circuit control valve II and the hydraulic control pump, and the main control module drives the bellows in the pulse pulsation generating device to move back and forth regularly, and checks in real time whether the pressure in the simulated blood vessel detected by the liquid circuit pipeline pressure detection sensor changes regularly, so as to judge whether the pulse pulsation generating device works normally; finally, the device starts to initialize, the bellows in the pulse pulsation generating device returns to normal state, the pressure in the simulated blood vessel returns to the preset pressure, and the system plays the pulse data.

[0069] In addition, by replacing simulated blood vessels with different elastic coefficients, the device of the present invention can carry out research on the effect of vascular elasticity on pulse, thereby further carrying out research related to arteriosclerosis. By allocating simulated blood with different viscosities, research on the effect of blood with different viscosities such as hyperlipidemia and hyperglycemia on pulse can be carried out. By changing the initialization pressure of the simulated blood vessels, research on the effect of different blood pressures such as hypertension on pulse can be carried out, thereby further carrying out research on the blood system, blood system diseases, chronic diseases, TCM diagnosis, and integration of Chinese and Western medicine.

[0070] The above is a detailed description of the specific implementation methods of the present invention, but the described contents are only preferred implementation methods of the present invention and cannot be considered to limit the implementation methods and implementation scope of the present invention. All equal changes and improvements made within the scope of the application of the present invention should still fall within the scope of the patent coverage of the present invention.
