Detailed Implementation
[0016] The present application will now be described in further detail with reference to the embodiments and accompanying drawings. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the application. Furthermore, it should be noted that, for ease of description, only the parts relevant to the application are shown in the accompanying drawings.
[0017] It should be noted that, unless otherwise specified, the embodiments and features of the embodiments in this application can be combined with each other. The present application will now be described in detail with reference to the accompanying drawings and embodiments.
[0018] The following describes in detail, with reference to the accompanying drawings, an electrocardiogram monitoring system, an electrocardiogram recorder, and a wearable device according to embodiments of this application.
[0019] Figure 1 This is a schematic diagram of an electrocardiogram (ECG) monitoring system according to an embodiment of this application. Figure 1 As shown, an electrocardiogram (ECG) monitoring system according to one embodiment of this application includes: a charging module 110 and a battery 120, a power supply circuit 130, an ECG measurement module 140, a pacing detection circuit 150, a communication and processing module 160, and an early warning module 170, wherein: The charging module 110 is connected to the battery 120. For example... Figure 1As shown, the charging module 110 includes a charging interface and a charging circuit, wherein the charging circuit is connected to the charging interface and the battery 120 respectively.
[0020] The charging circuit is powered by a built-in rechargeable lithium polymer battery, connected to an internal charging chip via a USB port, and the charging current is set by a configuration resistor. Testing showed that with a charging current of 63mA, charging is complete in approximately 2 hours.
[0021] The power supply circuit 130 is connected to the battery. The power supply circuit uses a high-frequency DC-DC converter chip to reduce the voltage to 3V to power the entire system. This chip operates at a high frequency above 1.4MHz, which causes less interference to the system and is easier to filter out compared to low-frequency DC-DC chips. Furthermore, the power supply circuit uses a P-channel metal-oxide-semiconductor (PMOS) for power path management, and the USB port can also power the system via PMOS. The system's operating current is <1mA. Testing has shown that the system can support more than 12 days of normal operation.
[0022] The electrocardiogram (ECG) measurement module 140 is connected to the power supply circuit 130. The ECG measurement module 140 is used to collect and process ECG signals to obtain ECG data.
[0023] In one embodiment of this application, such as Figure 1 As shown, the electrocardiogram (ECG) measurement module 140 includes: an ECG interface for acquiring ECG signals; and an ECG measurement circuit connected to both the ECG interface and the power supply circuit, which amplifies and converts the ECG signals to analog-to-digital data.
[0024] Specifically, the ECG interface uses a two-lead configuration, connecting to the human body via electrode pads. The ECG signal is input to the ECG measurement circuit through two contacts. The ECG measurement circuit employs a high-precision fully integrated chip to amplify and convert the ECG signal into analog-to-digital data, thus transforming the ECG signal into quantifiable ECG data. In this process, the integrated solution reduces system power consumption and size, while improving system reliability.
[0025] The pacing detection circuit 150 is connected to the electrocardiogram (ECG) measurement module, and the pacing detection circuit 150 is used to detect pacing signals based on the ECG data.
[0026] In one embodiment of this application, such as Figure 1 As shown, the pacing detection circuit 150 includes a filter circuit, an alarm circuit, and a latch circuit.
[0027] Specifically, after receiving ECG data, the pacing detection circuit 150 first preprocesses the data using a filter circuit to eliminate noise interference; then, the alarm circuit detects the preprocessed ECG data, and generates a detection signal when a pulse that meets the characteristics of a pacing signal is detected; the latching circuit latches the detected signal upon receipt to output the captured pacing signal.
[0028] The communication and processing module 160 is connected to the electrocardiogram measurement module 140, the pacing detection circuit 150 and the power supply circuit 130 respectively. The communication and processing module 160 is used to determine whether the electrocardiogram state is abnormal based on the electrocardiogram data and the pacing signal.
[0029] In one embodiment of this application, such as Figure 1 As shown, the communication and processing module 160 includes: a Bluetooth circuit and a Bluetooth antenna, wherein the Bluetooth circuit is connected to the Bluetooth antenna and the Bluetooth circuit integrates a microcontroller unit; a WIFI circuit and a WIFI antenna, wherein the WIFI circuit is connected to the WIFI antenna and the WIFI circuit integrates a microcontroller unit; a switching switch and a power switch, wherein the switching switch is used to switch the data read / write channel of the storage module, and the power switch and the switching switch are controlled by the Bluetooth circuit to control the opening and closing of the power switch and to switch the data read / write channel of the storage module through the switching switch; and a real-time clock circuit, which is connected to the Bluetooth circuit module and the power supply circuit respectively.
[0030] Specifically, the microcontroller in the Bluetooth circuit can identify whether the electrodes are making good contact with the skin by detecting specific locations in the acquired ECG data. Combined with the pacing signal output from the pacing detection circuit, it can determine whether the current ECG state is abnormal and the type of abnormality, thereby controlling the operation of the warning module. In addition, users can read real-time ECG data and waveforms via Bluetooth on their mobile phones.
[0031] Furthermore, the WIFI circuit utilizes a system-in-package (SoC) chip, integrating all peripheral components such as the ESP32 chip, Flash memory, crystal oscillator, filter capacitors, and RF matching link. This eliminates the need for external components, significantly reducing the required footprint. The WIFI chip also enables the export of large volumes of historical ECG data.
[0032] In one embodiment of this application, the real-time clock circuit is used to calibrate the internal clock of the Bluetooth circuit to record the real-time time of ECG signal acquisition.
[0033] Specifically, the real-time clock circuit uses a high-precision real-time clock chip and communicates with the microcontroller of the Bluetooth circuit through the integrated circuit bus (IIC) to calibrate the internal clock of the Bluetooth circuit. Thus, the real-time time of ECG signal acquisition can be recorded through the internal clock of the Bluetooth circuit.
[0034] The early warning module 170 is connected to the power supply circuit 130 and the communication and processing module 160 respectively. The early warning module is used to provide multi-form early warning when the electrocardiogram state is abnormal.
[0035] In one embodiment of this application, such as Figure 1 As shown, the early warning module includes: an indicator light and a button, wherein the indicator light is used to indicate the ECG status, and the button is used to turn the device on and off; and a buzzer is used to issue an early warning when an abnormal event is detected.
[0036] Specifically, RGB tri-color LEDs are used as indicator lights, with different colors used to indicate different ECG states, such as green for lead dislodgement and red for pacing abnormalities. Simultaneously, a buzzer and vibration motor provide further audible warnings to the user. This multi-faceted warning system ensures users receive timely alerts when their ECG status is abnormal, thereby reducing patient risk.
[0037] In one embodiment of this application, it further includes: a storage module 180, which is connected to the communication and processing module 160, and is used to: store the electrocardiogram data and the pacing signal, and be woken up when a data read / write request is received to provide read / write services for the electrocardiogram data and the pacing signal; and enter a sleep state after the read / write service is completed.
[0038] Using the above method, the storage module 180 is only woken up when data is read or written, which can significantly reduce the overall power consumption of the system. Furthermore, tests have shown that the SD-NAND memory used in this application can store 12 days of ECG data.
