Description

Technical Field

[0001] This invention relates to the field of telemedicine communication technology, specifically to a method for collecting and transmitting human pulse images by digitizing traditional Chinese medicine palpation tactile signals and realizing real-time reconstruction in a remote location. Background Technology

[0002] Currently, traditional Chinese medicine pulse diagnosis relies heavily on the tactile perception of the physician's fingers, such as the sensations of superficiality, depth, slowness, and rate, making it highly subjective and experience-dependent. Existing pulse diagnostic instruments are mostly limited to local data acquisition and waveform display, failing to address the uneven geographical distribution of high-quality traditional Chinese medicine medical resources. Although some remote diagnosis methods exist, most can only transmit static data or conduct simple video consultations, lacking the ability to recreate the dynamic tactile signal of "pulse beating" in real-time, high-fidelity remotely. This results in remote traditional Chinese medicine diagnosis losing the core "palpation" element. Summary of the Invention

[0003] To address the aforementioned technical shortcomings, this invention provides a method for collecting and transmitting human pulse data in real time online. This method aims to break the geographical limitations of traditional pulse diagnosis. It accurately collects simulated pulse signals through a client and converts them into digital signals. These signals are then relayed through a server, and finally, on the doctor's terminal device, the digital signals are reversed and converted back into a perceptible simulated pulse waveform or mechanical vibration, thereby enabling remote "pulse diagnosis."

[0004] This invention is achieved through the following measures: A method for acquiring and transmitting human pulse data in real time online includes the following steps: Step 1: Place the pulse acquisition device on the corresponding positions of the cun, guan, and chi points of the human body according to the pulse diagnosis method of traditional Chinese medicine, and use pressure sensors and body pressure sensors to collect simulated signals of the amplitude, frequency, and rhythm of the human pulse. Step 2: The pulse acquisition device converts the acquired analog signals into digital signals, then compresses them into digital pulse data packets, and sends the digital pulse data packets to the server in real time with low latency through the wireless transmission module. Step 3: After receiving the digitized pulse data packet, the server performs data verification and then forwards the data packet directly to the designated terminal device in real time. Step 4: After receiving the digitized pulse data, the terminal device uses a high-fidelity interpolation algorithm to accurately restore the digital signal to an analog signal. Based on the analog signal, the pulse waveform is displayed in real time through the display module. At the same time, the bionic mechanical structure on the terminal device restores the mechanical vibration or physical pulsation that is consistent with the pulse amplitude and frequency.

[0005] The bionic mechanical structure installed on the aforementioned terminal device includes a micro linear motor and a bionic heart composed of a bionic reservoir and a micro hydraulic pump. The bionic heart is connected to a hydraulic bionic blood vessel, and the micro linear motor drives a lifting mechanism used to simulate a pulse.

[0006] The aforementioned pulse acquisition device processes the acquired analog signals into pulse waveform data, pulse position information data, pulse strength level data, pulse rate value data, and timestamp data, and then converts them into digital signals and stores them in a digital pulse data package.

[0007] In step 1, the pulse acquisition device has a built-in micro air pump that simulates the three pulse-taking pressures of traditional Chinese medicine: "floating, middle, and deep," to achieve simultaneous acquisition of pulses from three different locations.

[0008] The transmission protocol adopts a lightweight real-time communication protocol to ensure end-to-end latency <200ms, and the restoration algorithm adopts a high-fidelity interpolation algorithm to ensure that the restored waveform is ≥85% consistent with the original acquired waveform.

[0009] The beneficial effects of this invention are: 1. Breaking through the limitations of time and space, it realizes the remoteization of the "palpation" process in traditional Chinese medicine, allowing experts in large cities such as Beijing to conduct real-time pulse diagnosis for patients in remote areas; 2. High-fidelity reproduction, abandoning the traditional remote consultation mode that relies solely on text descriptions or static images, and preserving the strength, rhythm, and morphological characteristics of the pulse to the greatest extent through a closed-loop conversion of "analog-digital-analog"; 3. Assisting in teaching and inheritance, this method can not only be used for clinical diagnosis and treatment, but also for the collection of pulse data and standardized teaching of renowned veteran TCM doctors, allowing students to repeatedly experience real typical pulse patterns through terminal devices. Attached Figure Description

[0010] Figure 1 This is a structural block diagram of the present invention; Detailed Implementation

[0011] The present invention will now be described in further detail with reference to the accompanying drawings: like Figure 1 As shown, a method for acquiring and transmitting human pulse data in real time utilizes a high-precision pulse acquisition device, such as a piezoelectric or pressure array sensor, deployed on the client and patient ends, closely attached to the radial artery at the cun, guan, and chi positions. The pulse acquisition device captures the simulated signal of the human pulse in real time, which includes the pulse amplitude (reflecting pulse strength), frequency / rate (reflecting pulse rate), and waveform characteristics.

[0012] The client's built-in signal processing module filters and amplifies the analog signal, then converts it into a high-precision pulse digital signal sequence via an analog-to-digital converter (ADC). The client then uploads the encapsulated pulse digital signal to a cloud server in real time via a network communication module (such as Wi-Fi, 4G / 5G, or Bluetooth gateway). The doctor's terminal device (such as a bionic pulse reproduction device or a diagnostic tablet with haptic feedback) retrieves the pulse digital signal from the server. The terminal device performs the following: 1. Visual Reproduction: Displaying a dynamic pulse waveform on the terminal screen in real time, perfectly synchronized with the patient's. 2. Tactile Reproduction: Driving a miniature linear motor, vibrating diaphragm, or hydraulic bionic blood vessel on the terminal device to generate mechanical vibrations or physical pulsations consistent with the patient's pulse amplitude and frequency, allowing the doctor to realistically feel the changes in the patient's pulse through touch.

[0013] Includes the following steps: Pulse Acquisition: The client-side pulse acquisition device is placed at the corresponding positions of the cun, guan, and chi points on the human body according to the traditional Chinese medicine pulse diagnosis method. It uses a high-precision pressure sensor (sensitivity ≥ 0.5mV / gram) and a body pressure sensor to collect simulated signals such as the amplitude, frequency (pulse rate), and rhythm of the human pulse. The acquisition device has a built-in miniature air pump that can simulate the three pulse-taking pressures of "superficial, middle, and deep" in traditional Chinese medicine, achieving simultaneous acquisition of pulse data from all three positions.

[0014] Analog-to-digital conversion: The built-in A / D conversion unit (≥12-bit precision, sampling rate ≥250Hz) performs high-precision analog-to-digital conversion on the analog pulse signal, generating a digital pulse data packet. The data packet includes: pulse waveform data, pulse position information (superficial / middle / deep), pulse strength level, pulse rate value, timestamp, etc.

[0015] Real-time transmission: The client transmits digital pulse data packets to the server in real time with low latency via a wireless transmission module (Wi-Fi / 4G / 5G / Ethernet). The transmission protocol uses a lightweight real-time communication protocol to ensure end-to-end latency <200ms.

[0016] Data relay: After receiving digitized pulse data, the server performs simple data verification and routing distribution, without complex cloud analysis and processing (a key difference from existing technologies), and directly forwards the data to the designated terminal devices in real time. The server supports simultaneous access from multiple terminals, enabling one-to-many real-time pulse distribution.

[0017] Digital-to-Analog Conversion and Waveform Restoration (Terminal Equipment): After receiving digitized pulse data, the terminal equipment uses a built-in D / A converter to accurately restore the digital signal to an analog signal, driving the display module (monitor / oscilloscope / dedicated restoration device) to present the pulse waveform in real time. The restoration algorithm uses a high-fidelity interpolation algorithm to ensure that the consistency between the restored waveform and the original acquired waveform is ≥85%.

[0018] Real-time display and interaction: The terminal device displays the pulse waveform in real time and simultaneously displays pulse parameters (pulse position, pulse rate, pulse rhythm, pulse strength, pulse shape, etc.), supporting doctors to remotely and in real time "pulse diagnosis".

[0019] The above description is only a preferred embodiment of this patent. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of this patent, and these improvements and substitutions should also be considered within the scope of protection of this patent.
