Description

Technical Field

[0001] The invention relates to research on modern application technology of traditional Chinese medicine, and in particular to an intelligent remote diagnosis system for traditional Chinese medicine pulse. Background Art

[0002] With the rapid development of the Internet and mobile medical technology, telemedicine, as a new medical model, is receiving more and more attention. Remote TCM pulse diagnosis technology refers to a technical means of remotely diagnosing pulse diagnosis in TCM through the Internet and communication technology, so that doctors can diagnose pulse of patients without direct contact with patients. Remote TCM pulse diagnosis technology can break through geographical restrictions, integrate high-quality medical resources, and improve the accessibility and efficiency of medical services.

[0003] The three parts and nine signs are one of the oldest pulse diagnosis methods in my country. It was first seen in the "Inner Canon of Medicine·Suwen". The Cunkou diagnosis method is a common three-part nine-sign diagnosis method in TCM clinical practice. The Cunkou location 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 three signs of floating, medium, and sinking according to the light, medium, and heavy finger pressure. They are collectively called "three parts and nine signs". The current pulse detection technology has developed from single-point detection to concentric circle dual-probe detection, array multi-point probe detection, and then to composite photoelectric, pressure, B-ultrasound and other composite pulse monitoring. However, it is quite different from the traditional TCM three-part nine-sign theory and pulse diagnosis method. The traditional TCM pulse diagnosis finger method is based on "three fingers in line" and "fingers alternate" when necessary. It is difficult for the existing pulse detection technology to achieve this. 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 device cannot realize the replay of the pulse of Cun Shang, Cun, Guan, Chi, and Cun Xia on the same flowing tube, nor can it replay 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 the pulse "position, number, shape, and momentum" for replay can the complete information unique to the clinical pulse be correctly restored.

[0004] At present, the research on remote diagnosis technology of traditional Chinese medicine is mainly based on multimedia video interaction and virtual reality based on Internet technology, focusing on traditional Chinese medicine inspection, questioning and voice diagnosis, while the research on remote diagnosis technology of "feeling" or pulse diagnosis is still in its infancy. The detection of three parts and nine hou of traditional Chinese medicine pulse and the playback of three parts and nine hou of pulse are the key issues to be solved in the remote diagnosis technology of traditional Chinese medicine pulse. Only when the remote playback of "feeling" or pulse diagnosis in the true sense is realized can we talk about remote diagnosis of traditional Chinese medicine. Summary of the invention

[0005] The present invention starts from the perspective of bionics and engineering, combines multi-sensor information fusion technology, and innovatively designs a TCM pulse remote diagnosis system. The collection end is based on the pulse collection hand of the Three Parts and Nine Hous of TCM, and the playback end is based on the pulse playback device of the Three Parts and Nine Hous of TCM. The four attributes of the pulse, "position, number, shape, and potential", are comprehensively considered for playback, truly realizing the complete restoration of clinical pulse information, and then realizing TCM pulse remote diagnosis and sharing of medical resources.

[0006] The technical solution adopted by the present invention is:

[0007] A TCM pulse remote diagnosis system comprises a TCM pulse acquisition terminal and a TCM pulse playback terminal, wherein the acquisition terminal and the playback terminal are connected via the Internet to realize the acquisition and remote playback of TCM pulse; wherein:

[0008] The TCM pulse acquisition end is composed of an acquisition end host computer, an acquisition end main control module, a three-part nine-hou pulse acquisition hand, a pulse sensor and signal processing module, a slidable hand pillow and a control module, and the acquisition end main control module is interactively connected with the acquisition end host computer; the three-part nine-hou pulse acquisition hand, the pulse sensor and signal processing module, the slidable hand pillow and the control module are connected with the acquisition end main control module; the acquisition end is based on the basic pulse diagnosis methods of TCM "taking the pulse from the inch-cun position alone" and "taking the pulse with both hands", and designs the TCM three-part nine-hou pulse acquisition hand and the control module, which can simulate 12 kinds of finger manipulations commonly used by traditional TCM practitioners, including lifting, pressing, taking the middle, searching, pushing, following, total pressing, single pressing, bending, looking up, manipulating and vertical, to realize the acquisition and analysis of the double-part three-part nine-hou pulse;

[0009] The Chinese medicine pulse playback end is composed of a playback end host computer, a playback end main control module, a pulse pulsation generating device, a simulated hand and Cun, Guan, and Chi pressure detection module, a liquid 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. The playback end main control module is connected to the playback end host computer; the pulse pulsation generating device, the simulated hand and Cun, Guan, and Chi pressure detection module, and the liquid pipeline pressure monitoring and feedback control module are connected to the playback end main control module; the playback end comprehensively considers the four attributes of the pulse, namely "position, number, shape, and potential", to perform playback, thereby truly realizing the complete restoration of clinical pulse information.

[0010] The traditional Chinese medicine pulse collection end, the three-part nine-hou pulse collection hand is composed of a palm, an index finger, a middle finger, a ring finger, a finger side swing mechanism, a main control module, a flange mechanism, etc. The index finger, middle finger, and ring finger collection fingers are composed of finger tips, simulated bones, simulated tendons, continuous joints, and motion controllers. The pulse sensor is installed on the finger tips of the collection hand. The finger motion controller is composed of a stepper motor and a capstan. One section of the simulated tendon is fixed on the finger tips, and the other section is connected to the capstan. When the stepper motor is driven by the capstan, it drives the simulated tendon to move, control the finger movement and bending, so as to simulate the common finger manipulation techniques of traditional Chinese medicine pulse diagnosis, such as lifting, pressing, taking, searching, pushing, following, total pressing, single pressing, pitching, raising, manipulating, and vertical. The finger side swing mechanism can control the index finger and the ring finger of the collection hand to swing to both sides; the flange mechanism can be connected to the mechanical arm; the pulse sensor on the finger tips collects the pulse information, which is amplified, filtered, and modulated by the signal processing circuit and then connected to the main control module of the collection end for AD conversion and then uploaded to the collection end host computer. The slidable hand rest and control module are composed of a flexible hand rest, a lead screw, a slide rail and a stepper motor. There are "bumps" on both sides of the upper end of the flexible hand rest. The "bumps" protrude directly against the radius of the human body to "calibrate" the closed position. An airbag is installed inside the flexible hand rest. The expansion degree of the airbag can be adjusted through the control module to facilitate adjustment of the wrist position of the person being tested. The flexible hand rest is installed on the slide rail slider to drive the flexible hand rest to slide. When the left hand or the right hand is placed, the flexible hand rest drives the left hand and the right hand to slide along the slide rail slider, and adjusts the expansion degree of the airbag inside the flexible hand rest to ensure that the dexterous hand collects the pulse accurately.

The simulated hand is composed of a silicone hand and hand skin, and an injection-molded arm with simulated blood vessels embedded in it. There is a bulge on the side of the front end of the injection-molded arm, which simulates the radial styloid process and the structure and finger feel of an adult's palm and arm; the Cun, Guan, and Chi pressure detection module is composed of a Cun, Guan, and Chi pressure detection board, a pressure sensor, and a latex module. Five pressure sensors can be placed on the Cun, Guan, Chi, and Chi pressure detection board to detect the pulse pressure at five locations: 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 vessels and peripheral tissues. There are four grooves under the latex module, which divide the latex module into five small modules. Each small module corresponds to a sensor to prevent interference with the pressure detection of adjacent locations after pressing at one location when taking the pulse. The liquid pipeline pressure detection and feedback control module consists of a liquid pipeline pressure detection sensor, liquid control valve I, liquid control valve II and a hydraulic control pump. By controlling the actions of liquid control valve I, liquid control valve II and the hydraulic control pump, the liquid volume in the simulated blood vessel is changed, and the simulated vascular filling degree is changed, thereby simulating the compliance of the vascular and restoring the static shape of the vascular. The simulated blood reservoir is a closed, transparent container, mainly used to store simulated blood; the main component of simulated blood is sodium carboxymethyl cellulose, and the viscosity will increase after adding water. After adding red dye, simulated blood of different viscosities can be prepared.

[0063] The schematic diagram of the slidable handrest and the control module is as follows: Figure 4 As shown, it is composed of a flexible hand pillow 16, a lead screw 15, a slide rail 14 and a stepper motor 18. There are "bumps" on both sides of the upper end of the flexible hand pillow. The "bumps" are facing the protrusion 17 of the radius of the human body, so as to "calibrate" the closed position. An air bag is installed inside the flexible hand pillow 16. The expansion degree of the air bag can be adjusted by the control module to facilitate the adjustment of the wrist position of the person being tested. The flexible hand pillow 16 is installed on the slide rail slider to drive the flexible hand pillow to slide. When the left hand or the right hand is placed, the flexible hand pillow drives the left hand and the right hand to slide along the slide rail slider, and adjusts the expansion degree of the air bag inside the flexible hand pillow to ensure that the position of the pulse is accurate when the dexterous hand collects the pulse.

[0064] The TCM three-part nine-hou pulse image replay device at the replay end is composed of a replay end main control module, a pulse pulsation generating device, a simulated hand and inch, guan, and chi pressure detection module, a fluid 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. The device structure is as follows Figure 5 , Figure 1 shown.

[0065] The pulse "number" and "force" 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 simulated hand radius position 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 liquid pipeline pressure monitoring and feedback control module in real time in the simulated vascular system, and the simulated vascular morphology is changed by adjusting the vascular filling degree by controlling the liquid control valve, hydraulic control pump, etc. The invention comprehensively considers the four attributes of the pulse "position, number, shape, and force" for reproduction, truly realizing the complete restoration of clinical pulse information, and laying a solid foundation for the realization of remote Chinese medicine pulse diagnosis.

[0066] Among them, the pulse pulsation generating device is the core component of the traditional Chinese medicine three-part nine-hou pulse image replay device, which determines whether the three-part nine-hou pulse image can be accurately replayed. The device consists of a liquid circuit interface 27, a bellows upper plug 28, a fixed platform 29, a bellows 30, a bellows lower plug 31, an oscillator 32, and a fixed base 33. The bellows 30 consists of an elastic tube body, a liquid storage cavity, an upper plug 28, and a lower plug 31. 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 bellows upper plug 28 is fixed on the fastening platform 29 and is connected to the simulated blood vessel 22 through the liquid circuit interface 27; the bellows lower plug 31 is fixed to the oscillator 32 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 drives the bellows elastic cavity to contract and relax, 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 vessels, and produce corresponding expansion and contraction at the simulated blood vessels, thereby forming a perceptible pulse pulsation. At the same time, the oscillator 32, the bellows 30, etc. are fixed together using a fastening platform 29 and a fixed base 33, which limits the bellows elastic cavity to only contract or relax, reducing the pulse playback error, reducing noise and vibration, and improving the stability and reliability of the three-part nine-hou pulse playback device.

[0067] The simulated hand and Cun, Guan, and Chi pressure detection modules, the simulated hand 19 is 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, and is composed of a silicone hand and hand skin, an injection molded arm, and is 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 joint. The structure of the Cun, Guan, and Chi pressure detection module 20 is as follows Figure 6As shown, it is composed of a Cun-Guan-Chi pressure detection board 38, a pressure sensor 37, and a latex module 35. Five pressure sensors can be placed on the Cun-Guan-Chi pressure detection board to detect the pulse pressure at five sites: Cun-Shang, Cun-Guan, Chi, and Chi-Xia. There is a simulated blood vessel placement groove 36 on the latex module 35, and the simulated blood vessel 21 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 divides the latex module into five small modules. Each small module position corresponds to a sensor, so as 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.

[0068] The liquid pipeline pressure detection and feedback control module is composed of a liquid pipeline pressure detection sensor, a liquid control valve I, a liquid control valve 2 and a hydraulic control pump. The liquid volume in the simulated blood vessel is changed by controlling the actions of the liquid control valve I, the liquid control valve 2 and the hydraulic control pump, and the simulated vascular filling degree is changed, so as to simulate the compliance of the vascular and restore the static shape of the vascular. In this process, the liquid pipeline pressure detection sensor detects the pressure in the simulated blood vessel in real time. Open the liquid control valve I, close the liquid control valve II, rotate the hydraulic control pump forward, drive the simulated blood pressure in the simulated blood reservoir into the simulated blood vessel system, increase the pressure in the simulated blood vessel, cause the simulated blood vessel to expand, and increase the vascular filling degree; open the liquid control valve I, close the liquid control valve II, and rotate the hydraulic control pump in the reverse direction, drive the simulated blood in the simulated blood vessel to flow back to the simulated blood reservoir, reduce the pressure in the simulated blood vessel, cause the simulated blood vessel to contract, and reduce the vascular filling degree. At the same time, open the 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.

[0069] The simulated blood storage container 34 is a closed transparent container for storing simulated blood. The main component of the simulated blood is sodium carboxymethyl cellulose, which is a food-grade thickener that is 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.

[0070] The workflow of the present invention includes three parts: the acquisition end acquires pulse information, the pulse information is transmitted over the Internet, and the replay end replays the pulse information. Among them, the main workflow of the pulse acquisition end of the three parts of traditional Chinese medicine is:

[0071] ① System startup self-test, mainly to check whether the pulse collection hand and flexible hand pillow are in the initial position, whether the pressure value detected by each pressure sensor is normal, etc.;

[0072] ② The person being tested chooses whether to test the "left hand" or "right hand". After the selection, the main control module of the acquisition end controls the sliding hand pillow module to automatically move to the "left hand" or "right hand" position; the person being tested places his hand on the flexible hand pillow, with the radial protrusion of the hand facing the "radial protrusion" mark position of the flexible hand pillow, and the person being tested adjusts the expansion degree of the airbag on the inner side of the flexible hand pillow to make the pulse collection position accurate;

[0073] ③ The pulse collecting hand moves to the detection position, and the index finger, middle finger, and ring finger of the collecting hand are pressed to the Cun, Guan, and Chi positions of the person being tested. The index finger, middle finger, and ring finger of the dexterous hand are fine-tuned radially (parallel to the arm cross section), and the radial artery fluctuation signal is detected in real time. The index finger, middle finger, and ring finger are adjusted to the position where the radial artery pulse fluctuation is the largest;

[0074] ④ The pulse acquisition hand simulates 12 common finger manipulation techniques of traditional Chinese medicine pulse diagnosis, including lifting, pressing, taking the middle, searching, pushing, following, total pressing, single pressing, leaning forward, leaning back, manipulating, and vertical, to collect pulse information in real time, and upload it to the host computer of the acquisition end after AD conversion by the main control module of the acquisition end;

[0075] ⑤ The host computer at the acquisition end receives the pulse information, displays the pulse signal in real time, calculates various parameters of the pulse chart and the pulse pressure, and compares them with the pulse diagnosis standard to determine what kind of pulse or combined pulse it is;

[0076] ⑥ After the test is completed, the person being tested is prompted to test the other hand; after the test of both hands is completed, the main control module of the acquisition end controls the pulse collection hand and the flexible hand pillow to return to the initial position, and the host computer of the acquisition end displays the pulse data of the three parts of both hands and the test and analysis results;

[0077] ⑦ The host computer at the acquisition end sends the pulse data to the host computer at the playback end via the Internet.

[0078] Among them, the workflow of the TCM three-part nine-hou pulse image playback terminal is as follows:

[0079] ⑧ Power-on self-test: After the system is powered on, the liquid pipeline pressure detection and feedback control module controls the operation of the liquid control valve I, liquid control valve II, and hydraulic control pump, drives the simulated blood in the liquid circuit to circulate, discharges the bubbles in the pipeline that may affect the pulse playback effect through the liquid circuit circulation, and detects whether there is any leakage in the liquid system;

[0080] ⑨ The host computer at the replay end selects the pulse data to be replayed, pre-processes the pulse data, and sends the basic pulse data and the pulse data at each pulse sampling position and pulse sampling pressure segment to the main control module at the replay end, and the replay end is ready to replay the pulse;

[0081] ⑩ The main control module at the replay end controls the pressure detection and feedback control module of the liquid pipeline to adjust the "blood pressure" in the simulated blood vessel to the "static pressure value" of the replay pulse data. After the simulated blood vessel reaches the "static pressure value", the pulse pulsation generating device is controlled to work and the pulse is replayed at the simulated hand Cun Guan Chi position;

[0082] At the same time, the main control module at the playback end receives the pulse position and pulse pressure detected by the Cun, Guan, and Chi pressure detection modules in real time, extracts the corresponding pulse data fragments in the playback pulse data according to the pulse position and pulse pressure, controls the pulse pulsation generating device to operate, and plays the pulse at the Cun, Guan, and Chi positions of the simulated hands, and repeats this process until the main control module detects that the pulse position and pulse pressure have not changed, and the main control module at the playback end automatically determines that the playback is finished;

[0083] The playback end starts initialization, the bellows in the pulse pulsation generating device returns to normal state, the simulated blood vessel pressure returns to the predetermined initial value, and waits for the next pulse data segment to be played back.

[0084] During the pulse re-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 re-release pulse, the re-release device will shut down automatically and alarm at the same time to prevent pipe burst and leakage.

[0085] The remote diagnosis technology of TCM pulse can break through geographical restrictions, integrate high-quality medical resources, and improve the accessibility and efficiency of medical services. It has important practical significance for alleviating the uneven distribution of medical resources and solving the problem of "difficulty and high cost of seeing a doctor" for patients in remote areas. The present invention 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 TCM pulse diagnosis.
