Description

Technical Field

[0001] This invention belongs to the field of physiological data acquisition technology, specifically referring to a multi-index physiological data acquisition device. Background Technology

[0002] In home and outdoor environments, the lack of power and Wi-Fi signals makes it impossible to collect data from individuals requiring physiological data. Furthermore, the uneven distribution of medical resources in my country currently hinders long-term monitoring and management.

[0003] Currently, many testing devices, such as various blood pressure monitors and blood glucose meters, cannot upload test data. They can only upload single indicators from a single manufacturer to the patient's own app, unable to share data with qualified professionals, thus preventing access to customized services. The FHG-1 portable multi-indicator physiological data acquisition device uses a small embedded system to acquire user physiological data from various commercially available physiological indicator acquisition devices via Bluetooth. This data is then transmitted to the cloud, allowing remote professional managers to view the user's physiological data and provide suggestions. Summary of the Invention

[0004] In view of the above situation and to overcome the shortcomings of the existing technology, the present invention provides a multi-indicator physiological data acquisition device, which effectively solves the problems currently on the market.

[0005] The technical solution adopted by this invention is as follows: This invention proposes a multi-index physiological data acquisition device, including a SoC chip, a voice playback module, a Bluetooth communication module, a Wi-Fi communication module, a 4G communication module, a user interaction module, and a data storage module. The SoC chip is electrically connected to the other modules respectively. It can acquire measurement data from commercially available physiological index acquisition devices through the Bluetooth communication module, and after being temporarily stored by the data storage module, it can be uploaded to the cloud service through the 4G communication module or the Wi-Fi communication module.

[0006] Furthermore, the user interaction module includes a full-color LED light and two function buttons, namely a red triangle button and a blue circle button, which can realize device wake-up, user binding identification, measurement item skipping and data upload cancellation functions, and support two users to share the device.

[0007] Furthermore, the physiological indicator acquisition devices include a blood pressure monitor, a blood glucose meter, a uric acid meter, and an electrocardiogram (ECG) monitoring device. The Bluetooth communication module supports pairing with the above devices using the common Bluetooth protocol to automatically acquire blood pressure, blood glucose, uric acid, and short-term ECG data.

[0008] Furthermore, the voice playback module pre-stores voice prompt data, which can play corresponding voice prompts when the device is woken up, a measurement project is started, a project is switched, data is uploaded, or operation instructions are given, without consuming data traffic in real time.

[0009] Furthermore, the data upload priority is given to the 4G communication module. When a Wi-Fi signal is detected, the data can be automatically switched to the Wi-Fi communication module for uploading. When there is no network, the data is temporarily stored in the storage module and automatically re-uploaded after the network is restored.

[0010] Furthermore, the measurement process includes the following steps: S1. Click any button to wake up the device; the device will automatically initialize. S2. The user clicks the binding button to trigger the measurement; S3. Voice prompts for measurement items; users can press any key within 10 seconds to skip the current item. S4. Automatically acquire and store the measurement data for the current project; S5. After completing all ordered items in sequence, a voice prompt will indicate that data is being uploaded. Users can press any key within 10 seconds to cancel the upload; the upload will proceed automatically after the timeout period.

[0011] Furthermore, the full-color LED lights use different colors and flashing frequencies to reflect the device status, including standby status, initialization status, measurement status, data upload status, and fault status.

[0012] Furthermore, the device has a built-in rechargeable lithium battery that supports continuous operation for ≥8 hours and standby time for ≥72 hours. It also features a low battery voice reminder function and uses a Type-C universal charging interface.

[0013] Furthermore, the data storage module supports storing ≥1000 physiological data points. The data is stored in an encrypted format and transmitted via SSL encryption when uploaded to the cloud, ensuring data security and privacy.

[0014] Furthermore, it can be adapted to scenarios without fixed power supply and unstable network, such as at home and in the wild, and supports communication with cloud management platforms, enabling professionals to view users' long-term physiological data in real time and provide customized intervention suggestions.

[0015] The beneficial effects achieved by the present invention using the above structure are as follows: The device integrates a 4G and Wi-Fi dual-mode communication module and has a built-in high-capacity rechargeable lithium battery. It does not rely on a fixed power source or network and can work stably in scenarios without power or Wi-Fi signal, such as at home or in the wild. It solves the pain point of traditional devices being limited by power and network and unable to be used in outdoor settings, allowing people with chronic diseases, outdoor workers, and others to complete physiological indicator measurements anytime and anywhere, greatly improving the flexibility and coverage of physiological monitoring. It supports Bluetooth pairing with commonly used blood pressure monitors, blood glucose meters, uric acid meters, and short-term ECG devices, allowing for the simultaneous collection of multiple core physiological indicators. This avoids the cumbersome process of repeatedly purchasing and measuring data from traditional single-indicator devices. Simultaneously, the data is uniformly stored and uploaded to the cloud, forming a complete personal health data profile. This provides professionals with comprehensive and continuous monitoring data, solving the problems of scattered and unintegrated data analysis associated with traditional devices.

[0020] like Figure 1-2 As shown, a multi-indicator physiological data acquisition device.

[0021] Example 1: Equipment Hardware Configuration and Structure (I) Selection of core components In this embodiment, the core hardware configuration of the FHG-1 data collector is as follows: SoC chip: The STM32H743VI high-performance microcontroller is selected, with a main frequency of up to 480MHz. It supports multi-module parallel processing, meets the requirements of simultaneous operation of multiple tasks such as Bluetooth data reception, voice playback, and network upload, and also has low power consumption characteristics, making it suitable for use in mobile scenarios.

[0022] Communication module: Bluetooth communication module: It adopts a BLE5.0 dual-mode module (model: CC2652R), which supports pairing with Bluetooth protocols (such as BLE4.0 / 5.0, SPP protocol) of commonly used blood pressure monitors, blood glucose meters, uric acid meters, and short-term ECG devices on the market. The communication distance is ≤10m and the data transmission rate is ≥1Mbps, ensuring fast and stable acquisition of measurement data.

[0023] Wi-Fi communication module: ESP8266 module is selected, which supports 802.11b / g / n protocol, is compatible with Wi-Fi networks in home, community and other scenarios, and has a data upload rate of ≥10Mbps.

[0024] 4G communication module: It adopts Quectel EC200S module, supports the 4G networks of the three major domestic operators, is compatible with LTE-FDD / LTE-TDD standards, and can reliably upload data in the absence of Wi-Fi, with a communication latency of ≤500ms.

[0025] Voice playback module: It adopts the WT588D voice chip, paired with an 8Ω / 1W miniature speaker, and has 20 pre-stored voice prompt data (such as "Device is awake, please click the binding button", "Blood pressure is about to be measured, please pay attention to the operation", "Data will be uploaded in 10 seconds, press any key to cancel", etc.). The voice volume can be preset to 60dB by the hardware circuit (suitable for clear listening in home, outdoor and other scenarios), and the playback response time is ≤100ms.

[0026] User interaction module: Full-color LED lights: RGB three-color LED beads are used, supporting switching between four colors: red, green, blue and yellow, as well as two states: constant light and flashing. Different combinations can be used to reflect the operating status of the device.

[0027] Function buttons: Waterproof tactile switches (model: TS-1185) are used. The two buttons are marked with a red triangle and a blue circle, respectively. The raised surface design facilitates blind operation. The lifespan of pressing is ≥100,000 times and the trigger response time is ≤5ms.

[0028] Data storage module: Equipped with a 16GB NAND Flash storage chip, it supports encrypted storage of ≥1000 physiological data records (each data record includes user ID, measurement index, value, timestamp, etc.), with a data storage life of ≥10 years, and the data can be preserved for a long time after power failure.

[0029] Power supply module: Built-in 3.7V / 2000mAh lithium polymer battery, paired with TP4056 charging management chip, supports 5V / 1A Type-C interface charging, charging time ≤3 hours, continuous working time ≥8 hours, standby time ≥72 hours, and triggers voice reminder when the battery is low (remaining battery ≤20%).

[0030] (ii) Hardware connection relationship The SoC chip serves as the core control unit, connecting to the Bluetooth, Wi-Fi, and 4G communication modules via I2C interfaces, the voice playback and data storage modules via SPI interfaces, and the full-color LED and two function buttons via GPIO interfaces. The power supply module provides stable voltage (3.3V / 5V) to each module through a DC-DC step-down circuit. The hardware circuit adopts a multi-layer PCB design with separate wiring for strong and weak currents to ensure the device's anti-interference capability. The overall size is controlled within 80mm×50mm×20mm, making it easy to handhold or carry.

[0031] Example 2: Equipment Software Flow and Function Implementation (I) System Initialization Process When the user clicks any function button, the device wakes up from standby mode, the full-color LED lights up green and flashes (frequency 1Hz), and the voice playback module plays "Device is awake and initializing".

[0032] The SoC chip initiates the initialization process, sequentially checking the working status of the Bluetooth communication module, Wi-Fi communication module, 4G communication module, and data storage module. After initialization is complete (time ≤ 3 seconds), the full-color LED light turns solid green, and the voice prompt "Initialization complete, please click your binding button" plays.

[0033] (II) User Binding and Measurement Process Suppose user A is bound to a button with a red triangle pattern, and user B is bound to a button with a blue circle pattern. When user A clicks the red triangle button, the full-color LED light turns to a solid yellow light, and a voice message appears saying, "User A has been identified. Measurement will begin soon. Please prepare."

[0034] The system starts the first measurement item according to the preset order of ordered items (default priority: blood pressure → blood sugar → uric acid → short-term ECG, which can be adjusted through the cloud platform), and the voice plays "You are about to measure your blood pressure. Please keep the blood pressure monitor connected to the device via Bluetooth and follow the instructions."

[0035] The Bluetooth communication module automatically searches for and connects to user A's blood pressure monitor (pairing and binding have been completed in advance, and the binding information is stored in the data storage module). After the blood pressure monitor completes the measurement, it automatically receives the blood pressure data (such as systolic pressure 120 mmHg and diastolic pressure 80 mmHg) and stores it in the Flash chip. At the same time, it plays a voice message: "Blood pressure measurement complete, blood sugar measurement is about to begin."

[0036] If user A does not need to measure blood glucose, they can click any button again within 10 seconds, and the system will play a voice message saying "Blood glucose measurement has been skipped, uric acid measurement is about to begin," and the system will directly enter the uric acid measurement process. If there is no operation within 10 seconds, the blood glucose measurement process will be started automatically, repeating the Bluetooth connection, data reception, and storage steps.

[0037] After all ordered items are completed in sequence, a voice message will play: "All items have been measured. Data will be uploaded in 10 seconds. Press any key to cancel." The full-color LED light will then flash blue (at a frequency of 2Hz). If the user presses any key, a voice message will play: "Upload has been canceled. Data has been saved." The LED light will then return to a solid green. If there is no operation within 10 seconds, the system will initiate the data upload process.

[0038] (III) Data Upload and Re-upload Process The data upload priority is set to prioritize the 4G communication module. The system first detects the 4G network signal strength (≥-85dBm is considered a good signal). If the signal is good, the stored physiological data is encrypted (using the AES-256 encryption algorithm) through the 4G module and then uploaded to the cloud management platform. After successful upload, the system will play a voice message saying "Data upload successful", the LED light will return to a solid green light, and the uploaded data will be deleted from the storage module.

[0039] If the 4G network signal is weak or absent, the system automatically switches to the Wi-Fi communication module to detect the Wi-Fi signal. If a paired Wi-Fi network is detected (SSID and password configured in advance via the cloud platform), data is uploaded via Wi-Fi. If the Wi-Fi network is also unavailable, a voice message will play: "No network currently, data has been temporarily stored and will be automatically uploaded after the network is restored." The LED light will then turn green and flash slowly (frequency 0.5Hz), and the data will be stored in the storage module.

[0040] Each time the device wakes up or detects network recovery (4G / Wifi signal meets requirements), it automatically starts the retransmission process, uploading the data that was not uploaded in the order of timestamps. After successful retransmission, the uploaded data is deleted synchronously.

[0041] (iv) Equipment status feedback rules Device status full-color LED light status corresponding to the scene The device remains powered on in standby mode with the green light constantly on, indicating it is not yet awake and awaits user input. The green light flashes (1Hz) during initialization, indicating the device is awake and is testing its modules. The yellow indicator light is constantly on, signifying that physiological indicators are being measured and data is being received. The blue light is flashing (2Hz) indicating that data is being uploaded to the cloud. The green light is flashing slowly (0.5Hz) when there is no network connection, indicating that data has not been uploaded and the network is waiting to be restored. A constantly lit red light indicates a module malfunction (such as a communication module error or storage failure). Low battery indicator light flashing red (1Hz): Remaining battery ≤ 20%, needs charging. Example 3: Verification in Real-world Application Scenarios (a) Application in home scenarios User C (a patient with hypertension and diabetes) uses the FHG-1 data collector at home. Clicking the blue circular button wakes up the device and binds it. The system then sequentially initiates blood pressure and blood glucose measurements: The electronic blood pressure monitor is connected via Bluetooth. User C wears the cuff according to the operating procedure of the blood pressure monitor. After the measurement is completed, the data acquisition device automatically receives the data (systolic blood pressure 135 mmHg, diastolic blood pressure 85 mmHg), and the voice prompts "Blood pressure measurement completed, value 135 / 85 mmHg".

[0042] The system automatically switches to blood glucose measurement, connects to the blood glucose meter via Bluetooth, and after user C's blood is drawn and measured, the collector receives the blood glucose data (6.8 mmol / L), and a voice prompt reads "Blood glucose measurement complete, value 6.8 mmol / L".

[0043] After all the data collection was completed, the data collector detected the home Wi-Fi network and automatically uploaded the data to the cloud 10 seconds later. The professional doctor viewed user C's long-term data (measured 3 times a week for 1 month) through the cloud platform and found that his blood pressure and blood sugar fluctuated little. He gave a customized suggestion to "maintain the current medication plan and monitor regularly".

[0044] (II) Application in Field Scenarios User D (an outdoor worker who needs to regularly monitor ECG and uric acid) uses the FHG-1 data logger while working in the field: Click the red triangle button to wake up the device. After system initialization, start ECG measurement and connect to the portable ECG monitor via Bluetooth. User D wears the electrode pads to complete a short ECG measurement. The data acquisition unit receives the ECG data (heart rate 75 beats / min, no abnormal waveform).

[0045] Switching to uric acid measurement, the system received uric acid data (380 μmol / L). After all items were completed, the data acquisition unit detected no Wi-Fi signal in the field and started uploading via 4G network, successfully uploading the data to the cloud.

[0046] User D later checked the cloud report, and professionals advised him based on his fieldwork environment to "pay attention to hydration, avoid high-purine foods, and have his uric acid levels checked regularly."

[0047] Example 4: Equipment Reliability and Safety Verification (a) Reliability verification Continuous operation test: After the device is fully charged, it runs the "wake-up-measurement-upload" process in a loop for 8 hours. All modules operate normally, with no data loss, voice lag, or communication interruption.

[0048] Environmental adaptability test: The equipment can work normally in a temperature range of -10℃ to 45℃ and a humidity range of 30% to 90% (without condensation), and the button pressing, LED display and voice playback functions are unaffected.

[0049] Interference resistance test: Bluetooth communication and 4G / Wifi upload functions are normal in household appliances (such as refrigerators and microwave ovens) or in outdoor electromagnetic environments, and data transmission is error-free.

[0050] (ii) Security verification Data security: Stored data is encrypted using AES-256, and uploaded data is transmitted via SSL encryption. No data leakage or tampering has occurred.

[0051] Electrical safety: The battery has overcharge, over-discharge, and short-circuit protection functions. The temperature during charging is ≤45℃, with no safety hazards. The equipment shell is made of flame-retardant ABS material, which meets the GB / T2408-2021 flame-retardant standard.

[0052] In practical use, the user wakes up the device by clicking any button. After the device initializes itself, the user can click their bound button to start their physiological indicator measurement process. Two buttons mean that this device and its corresponding testing equipment can be shared by two users, avoiding duplicate equipment purchases. After the user clicks their own button, the data collector will give a voice prompt to start measuring blood pressure, blood sugar, uric acid, or short-term ECG. The user can also press any key within 10 seconds to skip the current indicator check and proceed to the next check. After the current indicator starts, the user only needs to follow the operating procedure of the device for that indicator, such as the blood pressure monitor, to perform the corresponding operation. After completion, the FHG-1 will automatically obtain the measurement results, save them to the data collector, and start the measurement of the next item. After all the items ordered by the user are completed, the data collector will prompt the user to upload the collected data. However, if the user feels that the status of the collected data is incorrect, they can press any key to cancel the check. Otherwise, the data collector will automatically upload the data to the cloud service via the 4G network after 10 seconds. The voice player uses pre-stored voice playback data in the device. The above is the overall workflow of this invention. This step can be repeated for the next use. The actual operation process is very simple and easy to implement.
