Description

Technical Field

[0001] This invention relates to the field of medical device technology, and more specifically, to a device and method for dynamic electrocardiogram monitoring of myocardial infarction. Background Technology

[0002] Myocardial infarction is a fatal cardiovascular disease with a rapid onset and progression. Early identification of precursory abnormal electrocardiographic signals such as myocardial ischemia and malignant arrhythmias is crucial for reducing mortality and improving prognosis. Currently, Holter monitoring is one of the core methods used in clinical practice for screening high-risk groups for myocardial infarction and for monitoring postoperative rehabilitation.

[0003] In current clinical and civilian applications, vest-style wearable electrocardiogram (ECG) monitors are widely used for home-based long-term Holter monitoring due to their ease of wear, stable electrode fit, and lack of lead wire constraints. A typical structure includes: an elastic vest body, ECG detection electrodes distributed at corresponding positions on the vest, a terminal compartment fixed to the front of the vest, and a pluggable display terminal. The terminal compartment is electrically connected to all ECG electrodes. After the display terminal is inserted into the terminal compartment, it enables the acquisition, display, and storage of ECG data. The display terminal also has a built-in battery that powers the entire device.

[0004] However, the existing structure still has certain shortcomings in practical use. For example, as the sole power supply and control core, the display terminal must be completely disconnected from the charging unit when the user charges it, resulting in a complete interruption of ECG acquisition and data recording during the entire charging process. Myocardial infarction is characterized by its sudden onset, and peak charging times such as at night and after meals coincide with high-risk periods for myocardial ischemia and malignant arrhythmias. Interrupted monitoring can easily lead to missed detection of precursor signals and acute attack signals of myocardial infarction, delaying emergency treatment and potentially posing a safety hazard to high-risk groups. Summary of the Invention

[0005] The purpose of this invention is to provide a device and method for dynamic electrocardiogram monitoring of myocardial infarction, in order to solve the above-mentioned technical problems.

[0006] The present invention solves the above-mentioned technical problems through the following technical solutions: In a first aspect, the present invention provides a dynamic electrocardiogram monitoring device for myocardial infarction, comprising: an electrocardiogram signal acquisition module, a pluggable display terminal, a monitoring integration module, and a main control module; The display terminal has a built-in main power supply and a terminal control unit, which are used to display electrocardiogram data and enable human-computer interaction; The monitoring integration module includes: The terminal housing, electrically connected to the ECG signal acquisition module, is used to house and position the display terminal. A backup power supply is provided to power the ECG monitoring equipment while the display terminal is disconnected. The on / off control element is located in the power supply circuit of the backup power supply and is configured to: disconnect the power supply circuit of the backup power supply when the display terminal is inserted into the terminal compartment; and connect the power supply circuit of the backup power supply when the display terminal is removed from the terminal compartment. The switching circuit is electrically connected to the main power supply, the backup power supply and the core load of the equipment, respectively, and is used to realize uninterrupted power supply switching between the main power supply and the backup power supply during the plugging and unplugging of the display terminal. The main control module is electrically connected to the display terminal, the ECG signal acquisition module, and the monitoring integration module, and is configured as follows: In response to the insertion of the display terminal, the control switching circuit switches the power source to the main power supply and establishes communication with the display terminal to transmit ECG data; In response to the disconnection of the display terminal, the control switching circuit switches the power source to the backup power supply and controls the ECG signal acquisition module to independently acquire and store ECG data; In response to the re-insertion of the display terminal, the control switching circuit switches the power source back to the main power supply and synchronizes the ECG data during the removal with the display terminal.

[0007] Preferably, the on / off control element is a normally closed self-resetting push switch, with its pressing end aligned with the bottom pressing surface of the display terminal.

[0008] Preferably, the monitoring integration module further includes an automatic locking structure set on the terminal housing, used to automatically lock when the display terminal is inserted into place; the spring force generated when the push switch is reset is used to push the display terminal out a preset distance.

[0009] Preferably, the monitoring integration module further includes a charging management element that is electrically connected to the main power supply and the backup power supply respectively; The main control module is also configured to: after the display terminal is reinserted, obtain the power status of the backup power supply, and when the power level is lower than a preset threshold, control the charging management element to start the main power supply to charge the backup power supply.

[0010] Preferably, the main control module is further configured to: detect the remaining power of the main power supply, trigger a first-level warning when the power is below a first threshold, and trigger a forced charging prompt when the power is below a second threshold.

[0011] Preferably, the switching circuit uses an ideal diode ORing controller with a switching time of <1μs.

[0012] Preferably, the electrocardiogram (ECG) signal acquisition module includes a wearable vest and multiple ECG acquisition electrodes disposed on the wearable vest.

[0013] Secondly, the present invention also provides a method for dynamic electrocardiogram monitoring of myocardial infarction, applied to the aforementioned dynamic electrocardiogram monitoring device for myocardial infarction, comprising the following steps: S100, insert the display terminal into the terminal housing, trigger the on / off control element to disconnect the power supply circuit of the backup power supply; S200, the switching circuit switches the power source to the main power supply of the display terminal, and the main control module establishes communication with the display terminal to transmit ECG data; S300 will remove the display terminal from the terminal housing and trigger the on / off control element to turn on the power supply circuit of the backup power supply; S400, the switching circuit switches the power source to the backup power source the moment it is disconnected, ensuring that the ECG signal acquisition module continues to operate and monitoring is uninterrupted; In the S500, the ECG signal acquisition module independently completes the acquisition, analysis and local storage of ECG data while the display terminal is disconnected; S600 will re-insert the display terminal into the terminal housing, triggering the on / off control element to disconnect the power supply circuit of the backup power supply; S700, the switching circuit switches the power source back to the main power supply; S800: The main control module establishes communication with the display terminal to synchronize the ECG data during disconnection, forming a continuous monitoring record.

[0016] The beneficial effects of this invention are as follows: This invention achieves completely uninterrupted ECG monitoring when the display terminal is disconnected for charging by setting up a backup power supply, on / off control element, switching circuit and main control module independent of the display terminal; the backup power supply is automatically connected the moment the terminal is disconnected, and the ECG signal acquisition, analysis, storage and early warning are continuous throughout the process, ensuring that abnormal signals of myocardial infarction and acute attack signals are captured at all times, buying time for emergency treatment and providing safety guarantee for patients. In addition, the present invention, through its on / off control and microsecond-level electronic switching design, can prevent power outages, restarts, and data loss during plugging and unplugging. Even if the on / off control element fails, the switching circuit can still achieve priority management of the main and backup power supplies, ensuring uninterrupted monitoring and effectively meeting the power supply needs of sudden myocardial infarction scenarios.

Detailed Implementation

[0019] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.

[0020] Please refer to the following: Figures 1 to 4 A dynamic electrocardiogram monitoring device for myocardial infarction includes: an electrocardiogram signal acquisition module, a pluggable display terminal 201, and a monitoring integration module.

[0021] The ECG signal acquisition module includes a wearable vest body 101, which is made of medical elastic breathable fabric and has at least ten Ag / AgCl textile ECG acquisition electrodes 102 embedded in it, corresponding to the standard twelve-lead ECG acquisition position.

[0022] The pluggable display terminal 201 has a built-in main power supply and terminal control unit, and is equipped with a display screen and control buttons for displaying ECG data and human-computer interaction.

[0023] The monitoring integration module is fixedly installed on the front of the vest body 101. The monitoring integration module includes: terminal compartment 301, on / off control element 303, backup power supply 302, switching circuit 304, charging management element 307, and automatic locking structure 306.

[0024] The terminal housing 301 is made of medical flame-retardant PC material. It has an internal slot that matches the shape of the display terminal 201. The bottom of the slot has a conductive connector that is electrically connected to the bottom of the display terminal 201. After the display terminal 201 is inserted into the slot, the bottom interface of the display terminal 201 is connected to the conductive connector, so that the electrocardiogram signal acquisition module can establish communication with the display terminal 201. The terminal housing 301 also has a miniature vibration motor and a buzzer as an early warning structure. By making the terminal housing 301 vibrate and make a sound, it can remind the user of any abnormal situation.

[0025] The on / off control element 303 adopts a conventional normally closed self-resetting push switch. The self-resetting push switch is fixed to the bottom of the slot in the terminal housing 301, with its pressing end facing upwards. The pressing end of the self-resetting push switch is aligned with the pressing surface of the bottom of the display terminal 201, and the elastic force of the pressing end is greater than the weight of the display terminal 201, allowing it to lift the display terminal 201 upwards. This self-resetting push switch is connected in series in the positive power supply circuit of the backup power supply 302. When the display terminal 201 is inserted into the slot, its bottom presses against the self-resetting push switch, causing the power supply circuit of the backup power supply 302 to disconnect, and the backup power supply 302 to stop supplying power to the ECG signal acquisition module.

[0026] The backup power supply 302 typically uses a medical-grade lithium polymer battery and is installed inside the terminal compartment 301. The charging management element 307 is electrically connected to both the main power supply and the backup power supply 302, and is used to charge the backup power supply 302. The switching circuit 304 is electrically connected to the main power supply, the backup power supply 302, and the ECG signal acquisition module, and is used to achieve uninterrupted power supply switching between the main power supply and the backup power supply 302 during the insertion and removal of the display terminal 201. The switching circuit 304 preferably uses an ideal diode ORing controller, which can achieve microsecond-level (<1μs) automatic switching without voltage drops or reverse current backflow, ensuring continuous operation of the core load and uninterrupted monitoring during power switching.

[0027] The automatic locking structure 306 is mainly used to lock the display terminal 201 after it is inserted into the terminal compartment 301, preventing it from falling off during use. In a preferred embodiment, the automatic locking structure 306 includes a spring-loaded latch 3061 and an unlocking button 3062 that engages with the spring-loaded latch 3061. A locking groove adapted to the spring-loaded latch 3061 is provided on the side wall of the display terminal 201. After the display terminal 201 is inserted into place, the spring-loaded latch 3061 automatically engages with the locking groove on the side wall of the display terminal 201, achieving automatic locking. When the unlocking button 3062 is pressed, the spring-loaded latch 3061 retracts and unlocks, and the reset force of the button lifts the display terminal 201, exposing the top of the compartment for easy removal.

[0028] The main control module 305 is installed inside the terminal compartment 301. It typically uses an MCU controller and is equipped with local storage, data processing, and early warning units. It is electrically connected to the display terminal 201, the ECG signal acquisition module, and the switching circuit 304. The main control module 305 is configured to execute the following control modes: First control mode (display terminal 201 inserted): When the display terminal 201 is inserted into the terminal compartment 301, the bottom pressing surface presses the switch to disconnect it, physically cutting off the backup power supply 302 circuit. The main control module 305 detects that the switch is disconnected, and then controls the switching circuit 304 to switch to the main power supply. The real-time ECG data collected by the ECG signal acquisition module is synchronized to the display terminal 201 for display and storage.

[0029] Second control mode (display terminal 201 disconnected): When the user presses the unlock button 3062, the elastic latch 3061 retracts and unlocks, the press switch resets and conducts, and the backup power supply 302 circuit is connected; at the moment of disconnection (triggered by an interruption through a change in switch state), the main control module 305 controls the switching circuit 304 to switch to backup power supply 302, and the ECG signal acquisition module continues to operate; during disconnection, the ECG signal acquisition module independently completes the acquisition, analysis and storage of ECG data in the local memory.

[0030] Third control mode (display terminal 201 reinserted): After the display terminal 201 is fully charged and reinserted, the mechanical actions and power switching of the first control mode are repeated. After the display terminal 201 is inserted, it establishes communication with the main control module 305 and automatically synchronizes the ECG data stored in the local memory during the removal period to the display terminal 201 based on the timestamp, forming a continuous monitoring record. At the same time, the main control module 305 detects the power of the backup power supply 302. If it is lower than 20% (preset threshold), it controls the charging management element 307 to start the main power supply to charge the backup power supply 302. The charging will stop automatically after the backup power supply is fully charged.

[0031] Tiered power consumption warning: During daily use, the main control module 305 monitors the main power supply level in real time. When the level is ≤15%, the display terminal 201 triggers a first-level warning (screen pop-up and vibration) to prompt "The main battery power is low, please prepare to charge". When the level is ≤5%, a second-level emergency warning is triggered (continuous sound, light and vibration) to force the user to charge immediately.

[0032] The specific workflow of the dynamic electrocardiogram monitoring device for myocardial infarction provided by this invention is as follows: Daily wear: The display terminal 201 is inserted and locked, powered by the main power supply, and monitors, displays and stores ECG data in real time. The backup power supply 302 is disconnected and has sufficient power.

[0033] Low battery alert: When the main power supply level drops to 15%, a level 1 warning is triggered, prompting the user to prepare for charging.

[0034] Disconnect charging: When the user presses the unlock button 3062, the terminal automatically pops out. Upon disconnection, it seamlessly switches to the backup power supply 302 for power supply, and the compartment is independently monitored.

[0035] During charging: Display terminal 201 is charged separately, the compartment is continuously monitored, and the data is stored locally.

[0036] Restore to normal operation: After the display terminal 201 is fully charged and reinserted, it automatically locks, switches back to main power supply, synchronizes breakpoint data, detects the power of backup power supply 302 and starts replenishment, and resumes normal monitoring.

[0037] Repeating the above steps achieves 24-hour uninterrupted dynamic electrocardiogram monitoring for myocardial infarction. The embodiments of the present invention have been described above, but the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art, under the guidance of the present invention, can make many other modifications, all of which fall within the protection scope of the present invention.
