Description

Technical Field

[0001] The present invention relates to the field of intelligent pulse diagnosis in traditional Chinese medicine, and in particular to a cloud-based real-time interactive remote intelligent pulse diagnosis system in traditional Chinese medicine. Background Art

[0002] With the rapid development of information technology, the country has vigorously promoted the "Internet + Medical Health" action. Medical institutions are encouraged to use information technology such as the Internet to expand the space and content of medical services, and to build an integrated online and offline medical service model covering pre-diagnosis, during diagnosis, and after diagnosis; the remote intelligent pulse diagnosis system is the specific embodiment of "Internet + Medical Health" in the field of traditional Chinese medicine. The system uses Internet technology to break the limitations of time and space, so that patients can enjoy professional pulse diagnosis services without going to the hospital in person. For patients in remote areas, the remote intelligent pulse diagnosis system is even more significant. It can effectively solve the problem of uneven distribution of medical resources and enable more people to obtain high-quality traditional Chinese medicine services. At the same time, it is encouraged to develop telemedicine services and promote the sinking of high-quality medical resources. The remote intelligent pulse diagnosis system can realize remote interaction between doctors and patients. Doctors can make remote diagnoses based on the patient's pulse data and give personalized treatment plans. This not only improves the accessibility of medical services, but also provides strong support for the implementation of the hierarchical diagnosis and treatment system.

[0003] Judging from the current research status, there are many domestic research and development of intelligent pulse diagnosis device systems, which are developing rapidly; however, there are very few intelligent pulse diagnosis devices related to traditional Chinese medicine abroad, and most of them are concentrated on the preparation of flexible pulse sensors. There is a lack of device systems designed based on traditional Chinese medicine pulse diagnosis theory.

[0004] The current pulse diagnosis device has the following shortcomings: it does not realize real-time mutual transmission and communication between the patient and the doctor, that is, the finger method of the doctor is reproduced on the patient side, and the pulse of the patient is reproduced on the doctor side; the three-way pressurized pulse taking mechanism is not designed in parallel, which does not conform to the traditional Chinese medicine pulse diagnosis theory of "Cun, Guan, Chi"; the patient side does not have a pulse pressing function, which does not conform to the traditional Chinese medicine pulse diagnosis theory of "floating, middle, sinking"; there is no sound patient-side pulse database and doctor-side finger method database, which needs to be further improved through extensive pulse collection experiments; the patient-side pulse detection device is generally designed to be large, mostly desktop structure, lacking wearable and biocompatible design. Therefore, new systems, hardware and methods are urgently needed to realize a portable remote intelligent Chinese medicine three-part nine-hou pulse diagnosis system, integrating wearable patient-side pulse detection devices, doctor-side pulse reproduction devices, and cloud real-time interconnection functions, breaking through the geographical limitations of Chinese medicine diagnosis and treatment, opening up a new model of remote diagnosis and treatment, and providing new ideas for daily health testing. Summary of the invention

[0005] In order to overcome the above-mentioned deficiencies in the prior art, the present invention focuses on the urgent demand for remote intelligent diagnosis in the field of traditional Chinese medicine pulse diagnosis, and aims at the problems that the current intelligent pulse diagnosis system cannot realize remote two-end interaction, does not consider the design of the doctor's pulse reproduction device, the pulse collection device does not have both the pulse taking and pulse detection functions, and the pulse detection device is large in size and not portable. A cloud-based real-time interactive remote intelligent traditional Chinese medicine pulse diagnosis system is provided, which has both functions and a miniaturized wearable design, providing a new mode for remote intelligent diagnosis and treatment, and providing a new idea based on traditional Chinese medicine pulse diagnosis for daily health monitoring.

[0006] In order to achieve the above object, the present invention adopts the following technical scheme:

[0007] A cloud-based real-time interactive remote intelligent Chinese medicine pulse diagnosis system comprises a patient-side flexible pulse detection bracelet, a doctor-side pulse reproduction bionic hand and a cloud-based real-time interactive system.

[0009] The pulse reproduction bionic hand on the doctor's side includes: a doctor's side main control board, bionic skin, bionic blood vessels, bionic hand, voice coil motor and finger gesture collection sensors. Three voice coil motors are installed inside the bionic hand as the power source for the reproduction of the Cun, Guan and Chi pulses; three sections of bionic blood vessels are fixed on the top of the voice coil motors respectively, and the surface of the blood vessels is covered with silicone molds to imitate the skin on the radial part of the human wrist; three finger gesture collection sensors are attached between two layers of bionic skin, covering the surface of the bionic hand, to collect the finger gestures applied by the doctor at three positions.

[0010] The cloud real-time interactive system includes a patient-side user module, a doctor-side user module and a cloud server. The two-end user modules use the TCP protocol to communicate with the cloud server over the network to achieve two-way connectivity between the two-end data and the cloud server.

[0011] The upper cover plate of the watch case is connected to the watch case by two bolts, and two bosses are designed on both sides of the watch case and threaded holes are drilled to match the two holes on both sides of the upper cover plate of the watch case; a groove is opened in the middle of the upper cover plate of the watch case to display the middle display screen part of the LCD module; the upper cover plate of the watch case matches the four holes around the LCD module display screen by four bolts and nuts.

The server remotely transmits the pulse data to the doctor-side user module; the doctor-side user module transmits the pulse pressure value signal back to the patient-side pulse detection bracelet through the cloud server, and then controls the airbag to inflate and deflate to different degrees, thereby realizing the cloud interconnection function.

[0016] The finger technique acquisition sensor acquires the pulse pressing force applied by the doctor's three fingers, and then converts the force value into a voltage signal through the doctor's end main control board and transmits it to the patient's end. The pulse pressure application device on the patient's end takes the pulse and presses, and transmits the measured pulse signal back to the doctor's end in real time. The doctor's end reproduces the real-time fluctuating pulse signal based on the equivalent relationship between the pulse signal amplitude and the voltage mechanics of the voice coil motor; the signal amplitude of the force value acquired by the pulse sensor and the PWM duty cycle of the voice coil motor are calibrated to determine that the relationship between the signal of the patient's end pulse sensor and the PWM duty cycle of the voice coil motor quantitative action at the doctor's end satisfies the following formula:

[0017]

[0018] Where Data_Force is the force signal collected by the pulse sensor, and Data_PWM is the duty cycle of the voice coil motor. The quantitative reproduction of the pulse is achieved through the above mechanical equivalent relationship.

[0019] The patient-side and doctor-side user modules are developed using the Android studio tool in the Windows system on a PC, and the cloud server development environment is python; the patient-side and doctor-side user modules dynamically display the Cun, Guan, and Chi pulse data received via Bluetooth as a waveform graph, and also contain filtering options, and perform filtering based on real-time matching of the acquisition device based on the median filtering algorithm.

The side and bottom of the watch case are both arc-shaped, and the arc-shaped design of the bottom can make the watch case fit the human wrist more closely; two small bosses are designed on both sides of the top of the watch case, the bosses are 3mm higher than the inner wall of the watch case, and threaded holes with a diameter of 2mm are punched on the bosses, which are matched with the upper cover plate of the watch case through threaded connection; two grooves are opened at the bottom of the watch case, which are 15mm long and 14mm wide, serving as passages for wiring the micro piezoelectric pump and the airbag, and various electronic devices and pulse sensors; a pair of lugs are designed on the bottom of both sides of the watch case, with the inner surface spacing between the two lugs being 20mm, and the outer surface spacing being 30mm. A through hole with a diameter of 1mm is punched in the middle, which cooperates with the spring lugs to assemble the watch strap. The head of strap 1 and strap 2 is designed with a boss and a through hole with a diameter of 1.8mm, which is connected to the lug through a 20mm long 1.5mm diameter lug; strap 1 and strap 2 are designed with a series of grooves for mutual buckling and fixed cooperation of the airbag. The airbag is 80mm long and 20mm wide, with a small boss designed at both ends, which cooperates with the head and bottom grooves of the airbag respectively to achieve the fixation of the airbag; the head of the airbag is designed with an air hole and an air nozzle, which is connected to the air pump inside the case through a 2mm diameter air tube; the pulse force sensor uses RP-C7.6-LT-LF2 thin film sensor, three of which are attached to the surface of the airbag in parallel to detect the pulse signals of the three places of "Cun, Guan, Chi" on the radial part of the human wrist.

[0036] The patient-side circuit layout has an overall circuit height of 23mm and consists of three parts: an LCD display, a Bluetooth module, and a patient-side main control board. The LCD display is connected to the female connector on the main control board through a pin header; the Bluetooth module is located between the LCD display and the main control board and is connected to the horizontal female connector on the main control board through a pin header. The main control board has the functions of three-way pulse signal acquisition, micro-airbag quantitative inflation and deflation control, Bluetooth connection and signal transmission, and real-time display of pulse waveform.

[0037] The pulse reproduction bionic hand at the doctor's end includes bionic skin, bionic blood vessels, bionic hand, voice coil motor and finger gesture collection sensor. Three voice coil motors are installed inside the bionic hand as the power source for the reproduction of the three pulses of Cun, Guan and Chi; three sections of bionic blood vessels are fixed on the top of the voice coil motor respectively, and the surface of the blood vessels is covered with silicone mold to imitate the skin on the radial surface of the human wrist; three finger gesture collection sensors are attached between two layers of bionic skin and covered on the surface of the bionic hand to collect the finger gestures applied by the doctor at three positions. The bionic hand model is constructed by scanning the real hand, and its three-dimensional model is constructed by 3D printing technology. A groove is set to place three voice coil motors; three pairs of mounting holes are set at the bottom of the groove, which are connected to the threaded holes at the bottom of the selected 26VC002 voice coil motor; the front end and the rear end of the groove are connected, which serves as the passage for the voice coil motor and the sensor circuit. The bionic skin is made of AB glue, and the bionic blood vessel is made by 3D printing technology. It consists of three small cylinders with a diameter of 2mm, simulating the three blood vessel segments of Cun, Guan and Chi. Two threaded holes are set at the bottom of each bionic blood vessel, which are connected to the threaded holes on the top of the selected 26VC002 voice coil motor; the bionic skin made of AB glue is a sheet-like flexible structure, the bottom of the bionic skin is coated with glue, and is attached to the voice coil motor and the surface of the bionic blood vessel. The fingering acquisition sensor uses three RP-C10-LT piezoresistive film sensors, the surface of which is coated with glue and attached between the bionic skin composed of two layers of silicone, and aligned with the bionic blood vessel segments on the top of the three-way voice coil motor.

[0038] The doctor-side and patient-side user modules are interconnected with the cloud server through the TCP protocol to achieve remote real-time interaction. Specifically, 1. The pulse reproduction bionic hand on the doctor-side uses three thin-film pressure sensors to collect the pulse-taking pressure applied remotely by the doctor; 2. The doctor-side Bluetooth module transmits the voltage signal of the pressure to the doctor-side user module; 3. The doctor-side user module transmits the pulse-taking pressure data to the patient-side user module through the cloud server; 4. The pulse-taking pressure data is transmitted from the patient-side user module to the patient-side main control board; 5. The patient-side main control board adjusts and controls the degree of airbag expansion through the air pump-air valve circuit based on force feedback to achieve the remote pulse-taking pressurization process; 6. The patient-side airbag is pressurized and expanded to measure the pulse signal under different pulse-taking degrees, and the patient-side user module connects to the cloud server through the TCP protocol to transmit the pulse signal back to the doctor-side user module;

[0039] The doctor's main control board controls the voice coil motor to move to different degrees through PWM based on the correspondence between the calibrated force value and the PWM value, thereby realizing the remote pulse reproduction function.

[0040] Reference Figure 4 , including the following steps:

[0041] Step 1: Place three pulse sensors on the human wrist at the three positions of Cun, Guan and Chi, connect the two pins of each sensor to the two input pins of the linear voltage conversion module, and connect the AO output pin of the linear voltage module to the ADC pin defined by the STN32F407 main control board to achieve real-time detection of three pulse signals and pressing force;

[0042] Step 2: Circularly sample the pulse data through ADC, collect it once every 5ms, and take the average value every ten times to make the data fluctuation smooth. Since the collected force data is in hexadecimal, each force data is a string of data groups. The first data of each group of data is added with 0xFF as the data header, and the last data is added with 0xEE as the data tail, so as to achieve accurate identification of each force data, ensure the accuracy and integrity of the data, and then transmit the pulse signal to the doctor through the Bluetooth module;

[0043] Step 3: After receiving the pressure data from the doctor, the air pump is started to control the expansion of the airbag through the air valve. At this time, since the airbag is fixed between the strap and the wrist, the expansion of the airbag can achieve pressurization of the Cun, Guan, and Chi positions of the radial part of the wrist;

[0044] Step 4: To control the expansion degree of the airbag to be equal to the degree of remote compression by the doctor, the static pressure value measured by the sensor is compared with the value of the pressure sensor on the doctor's end. If the expansion degree of the airbag is greater than the target force value, the air pump is controlled to be closed, the solenoid valve is opened, and the airbag is deflated; if the expansion degree of the airbag is less than the target force value, the air pump remains in a working state and the solenoid valve remains in a closed state; if the expansion degree of the airbag is near the target force value, the air pump is controlled to be closed, the solenoid valve remains closed, and the airbag remains in a certain expansion state;

[0045] Step 5: Data transmission and display of pulse signals under different compression levels, and real-time display of data changes on the PC host computer through USART serial communication. At the same time, the patient-side main control board transmits the three-way pulse force value signals of Cun, Guan, and Chi under different compression forces to the patient-side user module through the Bluetooth module, and displays the waveforms. The three-way pulse force value data change waveforms are then further transmitted to the cloud through the user module and stored, providing a data basis for the generation of subsequent auxiliary diagnosis reports. At the same time, the pulse force value data is transmitted back to the doctor for reproduction, thus completing a remote pulse diagnosis process.

[0046] In order to restore the scene of Chinese medicine pulse diagnosis, fully simulate the pulse diagnosis method of pressing the wrist with the fingertips, and objectively obtain the best pulse, a pulse acquisition module with automatic pressurization function is designed based on the pressure sensor. This acquisition module requires the sensor to not only collect pulse signals, but also to be able to obtain pulse pressure. Among pressure sensors, piezoelectric and piezomagnetic sensors cannot meet the requirements in terms of sensitivity, resolution, and package size compared to piezoresistive sensors. Therefore, the RP-C10-LT piezoresistive pulse sensor (PVDF piezoelectric film) is selected. This pressure sensor is composed of a polyester film with excellent comprehensive mechanical properties and environmental protection, a highly conductive material, a graphene pressure-sensitive material, and an adhesive material. It can output pulse pressure and pulse signals, and can better realize the acquisition of pulse signals.

[0047] The strap-airbag structure and miniaturized circuit layout can effectively solve the problem that the current traditional pulse diagnosis devices are large in size and inconvenient to carry; the pressure feedback method can solve the problem of quantitative pressure application in intelligent pulse diagnosis devices, and is suitable for different pressurization schemes, and can be widely used in daily health monitoring, telemedicine and clinical pulse diagnosis.

[0048] Reference Figures 5 and 6 A remote real-time pulse mechanics equivalent reproduction device based on pressure feedback includes a bionic skin 12, a bionic blood vessel 13, a voice coil motor 14, a bionic hand 15, and a thin film force sensor located in the middle of the bionic skin. The three voice coil motors are respectively connected with the bottom of the inner groove of the voice coil motor through threaded connection; the three sections of bionic blood vessels are connected with the voice coil motor through threaded connection; the bionic skin is attached to the surface of the voice coil motor by glue, and the three sensors are attached between the two layers of bionic skin.

[0049] Reference Figure 7 , a cloud-based real-time interactive remote intelligent Chinese medicine pulse diagnosis system doctor-side pulse reproduction bionic hand, the doctor-side reproduction device has two main functions: receiving the patient's end pulse signals of Cun, Guan, and Chi under different degrees of compression, and quantitatively reproducing the pulse signals from the frequency and amplitude levels through three voice coil motors; collecting the pressing force of the doctor's three-way finger method, and remotely transmitting the force value signal to the patient for compression operation, specifically including the following steps:

[0050] Step 1: Calibrate the signal amplitude of the pulse sensor collecting force value and the PWM duty cycle of the voice coil motor to determine whether the relationship between the signal of the pulse sensor at the patient end and the PWM duty cycle of the voice coil motor controlling the quantitative action at the doctor end satisfies the following formula:

[0051]

[0052] Where Data_Force is the force signal collected by the pulse sensor, and Data_PWM is the duty cycle of the voice coil motor. The quantitative reproduction of the pulse is achieved through the above mechanical equivalent relationship.

[0053] Step 2: The doctor applies varying pulse pressure to three finger-collecting sensors in the bionic skin through finger techniques, and the pressure sensors convert the pressure signals into voltage signals.

[0054] Step 3: Use ADC to perform cyclic AD sampling on the doctor's finger pressure value data, collect it once every 5ms, and take the average value every ten times to make the data fluctuation smooth. Since the collected force value data is in hexadecimal, each force value data is a string of data groups. The first data of each group of data is added with 0xFF as the data header, and the last data is added with 0xEE as the data tail, so as to achieve accurate identification of each force value data, and then transmit the pressure signal to the doctor's user module through the Bluetooth module;

[0055] Step 4: The patient end collects force data under different pressing states through the pulse sensor. The force data is the combined force of the dynamically fluctuating pulse force and the static pressing force. After the force data is processed using the processing method of step 3, the patient end user module uses the TCP protocol to connect to the cloud server and transmit the force data back to the doctor end.

[0056] Step 5: The doctor receives the pulse data sent by the patient, finds the three corresponding pulse signals according to the data header 0xFF and the data tail 0xEE, and restores them from the split high and low bits; the restored signal is input into the voice coil motor drive after transformation through the relationship described in step 1, and the actual pressure value is measured by the pressure sensor, and compared with the pressure value of the pulse signal on the patient side. If the amplitude of the waveform data of the doctor's sensor is lower than that of the patient, the amplitude of the voice coil motor action is further increased, otherwise it is reduced. In this way, the three pulse signals of Cun, Guan, and Chi and the static pressing pressure reaction force are accurately and quantitatively restored;

[0057] Step six, display the doctor's finger signal and pulse signal in real time, display the data changes in real time on the PC host computer through USART serial port communication, and display the data waveform changes in real time on the doctor's user module through the Bluetooth module.

[0058] The bionic skin is made of AB glue. First, the A and B components are mixed evenly in a 1:1 ratio, placed in a vacuum to degas, and then poured into the mold silicon, vulcanized at room temperature for three hours; heated to 100°C and solidified for ten minutes. The bionic skin is attached to the surface of the bionic hand. The bionic blood vessels are made by 3D printing technology and consist of three small cylinders to simulate the three blood vessels of Cun, Guan, and Chi. The bionic blood vessels are matched with the mounting holes on the top of the voice coil motor through threads. The fingering acquisition sensor uses the RP-C10-LT piezoresistive film sensor. The pressure sensor is composed of polyester film with excellent comprehensive mechanical properties and environmental protection, high conductive materials and graphene pressure-sensitive materials, and adhesive materials. It can output pulse pressure and pulse signals, and can better realize the acquisition of fingering signals. The sensor is attached between the bionic skin composed of two layers of silicone films. The remote pulse reproduction device and method solve the problem of quantitative reproduction in current traditional devices, adopt more bionic designs, and combine the feedback reproduction method of pulse force and pressing force to make the touch feeling on the doctor's side more realistic and closer to the real scene of pulse diagnosis, and can be widely used in pulse diagnosis teaching and telemedicine.

Network data interaction includes receiving the "Cun, Guan, Chi" pulse data sent by the patient end through the cloud server, and sending the pulse diagnosis compression data collected by the doctor end hardware to the corresponding patient end through the cloud server; Bluetooth data interaction includes receiving the collected pulse diagnosis compression data from the doctor end device, and at the same time, the "Cun, Guan, Chi" pulse data sent from the cloud can be sent to the doctor end device when forming a remote pulse diagnosis system; data display can dynamically display the "Cun, Guan, Chi" pulse data received through the cloud as a waveform diagram in real time, and also contains filtering options, which can match the collection device for filtering; data storage can choose to save waveform data when receiving Bluetooth pulse data.

[0060] The present invention effectively solves the problem of remote intelligent pulse diagnosis, solves the problem that traditional pulse diagnosis equipment is large in size and not portable, and most devices do not consider different degrees of pressure to take the pulse. It provides a new model for remote intelligent diagnosis and treatment, and provides a new idea based on TCM pulse diagnosis for daily health monitoring.
