[0002] Common cardiovascular diseases include myocardial infarction and arrhythmia. Heart diseases often have a rapid onset, and the process from examination to diagnosis and treatment is often lengthy. If patients fail to receive timely diagnosis, precious treatment time will be wasted, potentially endangering their lives.

[0003] Electrocardiogram (ECG) signals directly reflect the activity of a patient's heart. Different atria and ventricles produce different ECG signals. Therefore, ECG signals are of significant reference value for initial screening of heart disease. Currently, ECG signals are widely used in the diagnosis and treatment of cardiology in clinical practice. ECG signals are one of the main means for doctors to assess the health of a person's heart. Relying on doctors to manually detect and analyze ECG signals is very time-consuming and inefficient, hindering timely diagnosis. Timely identification of ECG signals and rapid and accurate classification of abnormal signals will greatly improve diagnostic efficiency, buying patients more valuable treatment time.

[0004] A normal human electrocardiogram (ECG) signal consists of four periodic signals: the P wave, the QRS complex, the T wave, and the U wave. By analyzing the morphological characteristics and frequency information of the ECG signal, the location of heart lesions and potential causes can be deduced. Currently, there are many devices used for ECG detection, but most suffer from problems such as high power consumption, poor signal quality, and lack of real-time monitoring, which limits their practicality.

[0005] In view of this, this application aims to provide a portable real-time electrocardiogram (ECG) monitoring device based on low-power wireless transmission, so as to change the way ECG signals are detected, while meeting the requirements of low power consumption and real-time performance, thereby better meeting the application needs of ECG signal acquisition.

[0025] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] In the description of this utility model, it should be noted that the terms "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", "front", "back", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] like Figures 1-6As shown in the figure, the portable real-time ECG monitoring device based on low-power wireless transmission described in this embodiment includes a collector body 1 and lead wires. The collector body 1 has a PCB board 2 inside, and the PCB board 2 is provided with a signal acquisition module 21, a signal processing module 22, a data transmission module 23 and a power supply module 24. The signal acquisition module 21 uses 6-lead electrodes to acquire electrical signals. The signal processing module 22 is provided with a microcontroller and a hybrid filter. The data transmission module 23 is provided with an LTE module and a ceramic antenna. The power supply module 24 is provided with a power supply battery. The collector body 1 is provided with a socket 11 for inserting the lead wires. The socket 11 has two holes, and each hole has three lead points.

[0029] Specifically, the signal acquisition module 21 also integrates an AFE chip to acquire 6-lead electrocardiogram signals through an analog front-end circuit.

[0030] This embodiment features a simple and reasonable structure, employing a 6-lead electrode (flexible electrode sheet) design. It combines an AFE chip with a low-power microcontroller for ECG signal acquisition and filtering. Furthermore, by integrating an LTE module and a ceramic antenna, it enables real-time data upload and cloud storage and analysis, thus overcoming the limitations of traditional devices. In addition, this device uses a power supply battery and incorporates intelligent power management, resulting in a long battery life to meet the needs of long-term monitoring.

[0031] Specifically, the AFE analog front-end circuit (AFE) chip, STM32L4 microcontroller and filter circuit are packaged in the data acquisition unit 1, and the LTE baseband chip and ceramic antenna are built in, and the device is powered by a battery.

[0032] In use, connect the lead wires to the main body 1 of the data acquisition device. The six flexible electrode pads (combining chest and limb leads) are fixed to the patient's chest and limbs with medical adhesive tape. (See attached image.) Figure 4 As shown, this is the 6-lead position, which is reduced from the traditional 12-lead position. Through reasonable positioning, it ensures that the ECG signal covers the main areas of cardiac electrical activity for monitoring.

[0033] Specifically, such as Figure 5 The diagram shown is the main circuit structure diagram of the electrocardiogram signal acquisition described in this embodiment. When the AFE acquires the signal, the amplifier enhances the acquired electrocardiogram signal. The ADC (Analog to Digital Converter) in the AFE converts the acquired analog signal into a digital signal, which is then transmitted to the microcontroller through the SPI interface.

[0034] like Figure 6As shown in the diagram, the main circuit structure of the electrocardiogram signal processing described in this embodiment filters out noise such as electromyographic noise again through second-order IIR and 50th-order FIR, thereby improving the monitoring accuracy.

[0035] Based on the above embodiments, the microcontroller is set as an STM32L4 low-power microcontroller.

[0036] This embodiment employs the STM32L4 low-power microcontroller, which features low power consumption and high performance. While ensuring the device can process and analyze ECG signals normally, it can effectively reduce the device's power consumption, extend the device's usage time, improve the device's battery life, reduce the frequency of battery replacement or charging, and enhance the device's portability and practicality.

[0037] In some specific embodiments, the power supply module 24 is equipped with a low-power DC-DC converter.

[0038] In this embodiment, by setting a low-power DC-DC converter, the voltage of the power supply battery can be efficiently converted to provide a stable power supply for each module. At the same time, the energy loss during the conversion process is reduced, further reducing the overall power consumption of the device, improving energy utilization efficiency, and extending the service life of the device.

[0039] In some specific embodiments, the power supply battery is a rechargeable dual coin cell battery connected in parallel to provide power.

[0040] In this embodiment, parallel power supply of two coin cells can increase battery capacity and improve the device's battery life. Specifically, the two coin cells can be a combination of CR2032 and LIR2032, which are compact and have a battery life of more than 24 hours. They also support charging mode and are portable.

[0041] In some specific embodiments, the collector body 1 is provided with a waterproof outer shell.

[0042] In this embodiment, the collector body 1 is equipped with a waterproof shell, which can effectively prevent water from entering the device, protect the electronic components inside the device from damage, improve the waterproof performance of the device, and enhance the durability and reliability of the device.

[0043] In some specific embodiments, the back of the collector body 1 is provided with a battery compartment, and the battery compartment is provided with a snap-on cover.

[0044] The snap-on cover in this embodiment makes it convenient for users to replace batteries, improving the ease of use and safety of the device.

[0045] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
