[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art based on this application are within the scope of protection of this application.
[0024] See Figure 1 , Figure 1 This is a schematic diagram of the structure of the first miniature non-invasive cardiac function monitoring system provided in the embodiments of this application. The system includes a miniaturized hardware circuit board 11 and a miniaturized human-computer interaction terminal 12. The miniaturized hardware circuit board 11 includes a miniature data acquisition circuit 111 and a miniature control circuit 112.
[0025] Specifically, the miniaturized hardware circuit board 11 and the miniaturized human-machine interface 12 constitute a miniature non-invasive cardiac function monitor. The miniaturized human-machine interface 12 is integrated on the outer surface of the monitor, while the miniaturized hardware circuit board 11 is placed inside the monitor. The dimensions of the monitor are 150*90*20mm.
[0026] The miniature data acquisition circuit 111 includes an ECG / impedance integrated module 101, which non-invasively acquires ECG signals and chest impedance signals. In one embodiment of this application, the ECG / impedance integrated module 101 includes a 4-lead chest impedance electrode and a 2-lead ECG electrode. The ECG / impedance integrated module uses the 4-lead chest impedance electrode to acquire chest impedance signals and uses the 2-lead ECG electrode to acquire ECG signals.
[0027] The aforementioned ECG / impedance integrated module 101 also includes a signal acquisition chip, which acquires the signal collected by the electrodes, filters, amplifies and demodulates the signal, and acquires the processed ECG signal and chest impedance signal.
[0028] The micro control circuit 112 includes an MCU (Microcontroller Unit) main control module 102, a power management module 103, and a communication module 104; the miniaturized human-machine interface 12 integrates a miniature LCD screen 121.
[0029] The MCU main control module 102 acquires the signals collected by the micro data acquisition circuit 111, runs the built-in cardiac function monitoring method, and transmits the monitoring results to the miniaturized human-machine interface terminal 12 through the communication module 104. The miniaturized human-machine interface terminal 12 displays the monitoring results using the miniature LCD screen 121, and the power management module 103 supplies power to each module.
[0030] A schematic diagram of the miniaturized human-computer interaction terminal 12 is shown below. Figure 2 As shown, Figure 2 It includes a miniature LCD screen and buttons. The miniature LCD screen displays cardiac function monitoring parameters in real time, and users can trigger corresponding execution events by pressing the buttons.
[0031] The miniature LCD screen 121 is a miniature LCD screen with a size of 2.8 inches. It is used for real-time display and operation input. It is connected to the MCU main control module 102 via serial communication and the connection status is indicated by LED (Light-Emitting Diode Light) indicator.
[0032] The power management module 103 provides a stable power supply and manages the charging and discharging of the battery, which can be a rechargeable lithium battery. The power management module also integrates a charging management chip, supports USB charging, and provides regulated power to all modules. Through the sleep mode and dynamic power consumption management of the MCU main control module, a long battery life is achieved.
[0033] The monitoring results mentioned above include blood flow parameters such as cardiac output and stroke volume. Any existing method can be used for the cardiac function monitoring described above, and this application does not impose any limitations on this method.
[0034] As can be seen from the above, the system provided in this embodiment includes a miniaturized hardware circuit board and a miniaturized human-computer interaction terminal. The miniaturized hardware circuit board includes a miniaturized data acquisition circuit and a miniaturized control circuit. The system adopts a miniaturized and lightweight design. Compared with traditional cardiac function monitoring devices, it can achieve non-invasive cardiac function monitoring in a portable manner and can be flexibly applied to various daily scenarios such as home and outdoors.
[0035] Furthermore, the miniature data acquisition circuit includes an integrated ECG / impedance module, which allows a single module to simultaneously acquire ECG and chest impedance signals, avoiding cumbersome and complex operating procedures. Through a miniaturized human-computer interaction terminal, cardiac function parameters are displayed in real time, allowing users to understand their cardiac function status and reducing the difficulty of interpretation.
[0036] See Figure 3 , Figure 3 This is a schematic diagram of the structure of a second type of miniature non-invasive cardiac function monitoring system provided in an embodiment of this application. (The preceding text appears to be incomplete and requires further context.) Figure 1 Based on the corresponding embodiments, the above system also includes a remote monitoring terminal 13.
[0037] The remote monitoring terminal 13 includes a PC (computer) platform display terminal 131 and a data storage server 132. In addition, the aforementioned communication module 104 also includes a wireless communication module.
[0038] The wireless communication module 1041 supports multi-mode transmission via Bluetooth, WiFi, 4G, and 5G. The WiFi module is primarily used in home scenarios, directly connecting to the router and uploading data to a remote monitoring device. The 4G / 5G module is primarily used in outdoor scenarios. The Bluetooth module can connect to the user's smart devices, such as smartphones, smart bracelets, and smartwatches. As can be seen, through this multi-mode transmission mechanism, low-power transmission (WiFi) is ensured in the home environment while achieving full coverage in outdoor mobile scenarios (4G / 5G), solving the problem of intermittent monitoring when home devices are out and about, allowing for continuous data collection when patients are seeking medical treatment or are away from home.
[0039] The MCU main control module 102 transmits the monitoring results to the remote monitoring terminal 13 via the wireless communication module. The remote monitoring terminal 13 displays the monitoring results on the PC platform display terminal 131 and stores the monitoring results in the data storage server 132. The data storage server 132 stores the monitoring results according to the timestamp and can also periodically generate user cardiac function monitoring reports, which can be pushed to both doctors and patients via email and other means.
[0040] The remote monitoring terminal 13 is deployed in medical institutions, allowing medical staff to remotely view patients' cardiac function.
[0041] In one embodiment of this application, the miniaturized human-computer interaction terminal 12 further includes a multimodal communication module 122. The multimodal communication module 122 establishes a connection with the remote monitoring terminal 13 through a wireless communication module, and the user uses the multimodal communication module 122 to communicate with remote medical personnel.
[0042] The aforementioned multimodal communication module 122 includes a video communication module and an audio communication module.
[0043] The audio communication module is also connected to the MCU main control module 102 via the communication module 104. When the monitoring results obtained by the MCU main control module 102 are abnormal, the audio communication module outputs a monitoring abnormality alarm in natural language. For example, when the MCU main control module 102 detects abnormal heart rhythm or abnormal cardiac output, it triggers the audio communication module to play a pre-recorded alarm voice. Users can initiate a video call request through the video communication module so that medical staff can view the real-time waveform and guide users to adjust electrode positions, etc.
[0044] As can be seen from the above, the system also connects to a remote monitoring terminal, forming a closed loop for remote diagnosis; professional medical institutions can communicate with patients in a timely manner and view data in real time through cloud collaboration and multimodal communication modules, thus solving the medical dilemma of home monitoring for patients.
[0045] The above description is merely a preferred embodiment of this application and is not intended to limit the scope of protection of this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application are included within the scope of protection of this application.
