Description

Technical Field

[0001] This invention relates to the field of cardiopulmonary resuscitation (CPR) technology, and in particular to an intelligent interactive AED emergency training system and method for teaching demonstrations. Background Technology

[0002] The statements in this section are merely background information related to this application and do not necessarily constitute prior art.

[0003] In the early stages of cardiac arrest, 85%–90% of cases are ventricular fibrillation (VFI). The most effective treatment for VFI is early defibrillation using an AED (Automated External Defibrillator). After VFI occurs, defibrillation is most effective within 3–5 minutes; for every minute defibrillation is delayed, the survival rate decreases by 7%–10%. Approximately 540,000 people die from cardiac arrest in my country each year. Providing AEDs in public places is a crucial measure to reduce sudden cardiac death. AED defibrillation is an important step in CPR (Cardiopulmonary Resuscitation). The person using the AED is the AED / CPR practitioner (hereinafter referred to as the practitioner), and the person receiving AED defibrillation is the AED / CPR recipient (hereinafter referred to as the patient).

[0004] Currently, AEDs are widely deployed in public places outside of hospitals to provide timely assistance to patients suffering from sudden cardiac arrest. Because AEDs are life-threatening devices, their operation typically requires highly trained practitioners with basic life support skills and professional medical personnel. However, insufficient public knowledge of AED use and first aid leads to low efficiency in emergency care. Therefore, it is necessary to develop an intelligent, interactive AED first aid training system and related technologies for educational purposes to improve public awareness and skills in first aid.

[0005] In the process of developing this invention, the applicant discovered that existing technologies for AED first aid training still have at least the following problems:

[0006] 1. Current AED first aid training usually only targets one student for instruction. However, there are usually more than one student in AED first aid training. The lack of interaction among students during the teaching process leads to an increase in learning time and cost.

[0007] 2. Current AED emergency training lacks interaction between the AED user (trainee), the patient (rescue dummy), and the defibrillator. This makes it difficult for trainees to intuitively understand the actions of the device they are operating, the actions during radial cardiopulmonary resuscitation, and whether the patient's relevant signal parameters are correct. Consequently, the training is not effective.

[0008] 3. Current AED emergency training usually only trains practitioners (trainees) on how to use patients (emergency dummies) and defibrillators. With the development of existing AED emergency platforms, remote guidance from emergency personnel has emerged during the use of AED devices. The existing AED emergency training system has lost this aspect.

[0009] Therefore, how to solve the problems existing in the AED first aid training process mentioned above has become the subject of this invention. Summary of the Invention

[0010] The purpose of this invention is to provide an intelligent interactive AED first aid training system and method for teaching demonstrations.

[0011] To achieve the above objectives, the first aspect of the present invention proposes an intelligent interactive AED first aid training system for teaching demonstrations. The intelligent interactive AED first aid training system includes a first aid dummy, a training configuration terminal, a display terminal, a first aid platform, an intelligent AED device, an intelligent AED outer casing, a central control platform, and at least one of the following: a mobile terminal, an AED device Internet of Things platform, a navigation module, and a remote guidance platform.

[0012] The emergency rescue dummy is used to simulate patients who need emergency treatment due to falls or cardiac abnormalities. The emergency rescue dummy is equipped with an identification module for recognizing the rescue process, and the identification module collects identification information.

[0013] The training configuration terminal is a device that interacts with first aid trainees at least to set first aid training parameters and control the demonstration process, and the training configuration terminal has a first aid training system.

[0014] The display terminal is a device used to display interactive content during AED first aid training, and the display terminal has a display system.

[0015] The emergency rescue platform is used to respond to the information of the emergency rescue dummy falling to the ground, generate an emergency rescue code, and send out a distress message to the outside world.

[0016] The intelligent AED device is an AED device that has at least the functions of reminder, navigation and guidance for rescue.

[0017] The smart AED outer box is a box used to store smart AED devices and has at least the functions of reminder and positioning.

[0018] The mobile terminal is a device provided to those seeking help or volunteers for remotely receiving and responding to distress calls.

[0019] The AED device IoT platform is used to collect the action information of the AED device and the AED outer box in real time, and to send control commands to the AED device and the AED outer box.

[0020] The navigation module is used to guide the person in need of help and the volunteer to the shortest path to the AED device or the location of the emergency, based on the location information of the person in need of help, the volunteer, and the AED device.

[0021] The remote guidance platform is a device that provides audio and video communication to first aid trainees and first aid instructors based on remote guidance requests issued by intelligent AED devices.

[0022] The central control platform is used to receive and forward signals and instructions from various devices and systems in real time.

[0023] The intelligent interactive AED first aid training system is configured to use multiple interactive relationships between two or more of the above to complete the entire intelligent interactive AED first aid training process.

[0024] A second aspect of the present invention provides an intelligent interactive AED first aid training method for educational demonstrations, the intelligent interactive AED first aid training method comprising:

[0025] To build an intelligent interactive AED first aid training scenario based on interactive relationships, an interactive relationship must be established between at least two or more of the following: first aid trainees, first aid instructors, training configuration terminals, first aid training systems, display terminals, display systems, mobile terminals, first aid platforms, first aid dummies, intelligent AED devices, intelligent AED outer boxes, central control platforms, and remote guidance platforms. The intelligent interactive AED first aid training scenario is built from the above interactive relationships, where first aid trainees include current first aid trainees and observing first aid trainees.

[0026] Configure and conduct simulated emergency response activation interaction for intelligent interactive AED emergency training. Based on the interaction between the emergency trainee and the training configuration terminal and emergency training system, emergency parameters are configured. Based on the interaction between the training configuration terminal, central control platform, and display terminal, the display content corresponding to the emergency parameter information is synchronously displayed to the emergency trainee through the display terminal. Based on the interaction between the emergency trainee, training configuration terminal, emergency dummy, emergency platform, central control platform, and display terminal, the display content corresponding to the emergency dummy's simulated fall and distress call information is generated and synchronously displayed to the emergency trainee through the display terminal.

[0027] This simulated emergency preparedness interaction system, designed for responding to distress calls and providing intelligent interactive AED first aid training, involves interaction between the trainee, mobile terminal, emergency platform, intelligent AED device, and intelligent AED case. The trainee receives and responds to distress calls via mobile terminal and intelligent AED case. The interaction between the emergency platform, central control platform, and display terminal simultaneously displays the process of responding to the distress call to the trainee. Finally, the interaction between the trainee, intelligent AED device, central control platform, and display terminal also simultaneously displays the corresponding information after the trainee arrives at the patient's location with the intelligent AED device.

[0028] The system enables intelligent interactive AED emergency confirmation and remote emergency guidance interaction. Based on the interaction between the emergency trainee, the emergency dummy, the remote guidance platform, and the intelligent AED device, the current emergency trainee turns on the intelligent AED device, which connects to the remote guidance platform. The current emergency trainee monitors the status of the emergency dummy based on the alerts from the intelligent AED device and the prompts from the remote emergency guide. Based on the interaction between the emergency trainee, the remote guidance platform, and the display terminal, the corresponding display content of the current intelligent interactive AED emergency and remote emergency guidance interaction is synchronously displayed to the emergency trainee through the display terminal.

[0029] The interactive AED first aid training program involves the trainee interacting with a first aid dummy, a remote guidance platform, and the AED device. The trainee attaches the AED's electrodes to the dummy's chest. The AED automatically analyzes and determines that defibrillation is possible. The trainee then uses the AED and / or the remote guidance platform to perform defibrillation. If defibrillation is not needed, the trainee performs CPR as instructed by the AED and / or the remote guidance platform until the first aid is complete. Based on the interaction between the trainee, the remote guidance platform, and the display terminal, the corresponding content is simultaneously displayed to the trainee via the display terminal.

[0030] The relevant content of this invention is explained as follows:

[0031] 1. By implementing the above-mentioned technical solution of the present invention, and addressing the problems in existing AED first aid training such as the lack of interaction among trainees, the lack of interaction between the AED practitioner (trainee), the patient (first aid dummy), and the defibrillator, as well as the lack of interaction for remote guidance, an innovative intelligent interactive AED first aid training system and method with more complete and effective intelligent interaction and corresponding factual feedback for teaching demonstrations is designed. In this intelligent interactive AED first aid training system and method, multiple interactive relationships between various devices and personnel are used to complete the entire intelligent interactive AED first aid training process. Trainees can simulate real-life scenarios, use the emergency call function of the emergency platform to notify emergency volunteers immediately, and quickly find the nearest AED device through the navigation function of the emergency platform. Animations of each first aid step are displayed in real time on a large screen, linked to the trainee's operation, helping the trainee learn the first aid process more quickly and effectively. Other trainees watching on-site can also learn more intuitively and synchronously. The recognition module on the intelligent AED device performs real-time analysis of AED and CPR data. Analysis shows that there is no need to add additional cameras or CPR feedback devices to collect data on the first aid process. Simultaneously, remote video calls are conducted through a remote guidance platform, allowing trainees to communicate remotely with experienced first aid instructors during training. The system provides real-time guidance on trainees' first aid procedures, based on real-time interaction and feedback. Trainees can immediately understand whether their actions are correct, making training more efficient and convenient. The richer, more practical, and more efficient interactive relationships implemented in this intelligent interactive AED first aid training system, along with their interdependence, make the training process more closely aligned with real-world scenarios and more suitable for trainees with varying levels of first aid skill proficiency. This provides high-quality instruction, allowing trainees to more intuitively understand whether their current first aid actions are standardized and receive timely feedback. It also allows other trainees to participate in the intelligent interactive AED first aid training simultaneously through the display terminal, avoiding the predicament of a single intelligent interactive AED first aid training system being used only by one current trainee. This significantly improves the training needs of a batch of trainees and saves on venue and equipment costs.

[0032] 2. In the first aspect of the above technical solution, the training configuration terminal is a training configuration terminal computer, and the first aid training parameters set by the training configuration terminal include at least the scenario, human characteristics, and heart rhythm type; the first aid training system is a training configuration terminal program on the training configuration terminal computer that interacts with the user through an interface.

[0033] 3. In the first aspect of the above technical solution, the display terminal is a display terminal that displays the emergency rescue process animation and cardiopulmonary resuscitation parameters in real time, providing visual feedback to emergency rescue trainees; the display system is a TV program on the display terminal that automatically plays corresponding scene animations, emergency codes, emergency information, identification information, and emergency operation animations according to the signals and instructions of the central control platform, providing visual feedback to emergency rescue trainees.

[0034] 4. In the first aspect of the above technical solution, the identification module includes an electrode identification module for identifying and determining whether the emergency dummy meets the discharge conditions, an electrocardiogram identification module for identifying electrocardiogram signals and determining the selection of an electric shock strategy, and a cardiopulmonary resuscitation identification module for identifying and analyzing cardiopulmonary resuscitation compression actions.

[0035] 5. In the first aspect of the above technical solution, the simulated emergency dummy has a built-in electrocardiogram (ECG) signal generator, which includes a digital signal processor, a digital-to-analog converter, a signal conditioning circuit, an electrode interface, and a power supply module. The electrode identification module is attached to the corresponding position of the simulated emergency dummy. The ECG signal generator periodically emits electrical pulses of a specified form, which are transmitted through wires, conductive patches, and electrode patches and then received by the intelligent AED device. The intelligent AED device analyzes the received signals and determines whether the emergency dummy meets the discharge conditions.

[0036] 6. In the first aspect of the above technical solution, the ECG recognition module performs filtering preprocessing on the ECG signal received by the intelligent AED device, and then performs amplitude detection to determine whether it is a cardiac arrest signal. If it is a cardiac arrest signal, no further processing is performed, and it belongs to an unshockable rhythm; otherwise, feature extraction is performed, and a decision is made based on the feature vector. If the feature vector meets the conditions of ventricular fibrillation or rapid ventricular tachycardia, it is determined to be a shockable rhythm, and defibrillation treatment is suggested for the patient; otherwise, it is determined to be an unshockable rhythm; and the patient's heart rhythm is continuously identified throughout the entire treatment process.

[0037] 7. In the first aspect of the above technical solution, the emergency rescue platform includes an emergency response module, which includes an emergency QR code generation module, an emergency call module, and an emergency express line mini-program;

[0038] The emergency QR code generation module is used to generate an emergency QR code based on the personal and geographical information recorded in the emergency event after the emergency dummy simulates a fall.

[0039] The emergency call module is used to be responded to by users holding mobile terminals. The response methods include at least using the mobile terminal to scan the emergency QR code to query the corresponding emergency event details, and being notified of the emergency event details by responding to the reminder function of the AED box.

[0040] The emergency rescue platform is equipped with an emergency hotline mini-program, which sends distress messages to nearby emergency volunteers, smart AEDs, and smart AED boxes.

[0041] 8. In the first aspect of the above technical solution, the data transmission between the central control console and the emergency training system, the display system, and the emergency platform adopts the HTTP protocol; the data transmission between the intelligent AED device and the AED device IoT platform and the central control platform adopts the MQTT protocol; and the data transmission between the intelligent AED outer casing and the central control platform adopts the AMQP protocol.

[0042] 9. In the first aspect of the above technical solution, the intelligent interactive AED first aid training system further includes a data storage module, which is used to store the operation data and training records implemented during the interaction between the current first aid trainee and the first aid dummy, training configuration terminal, display terminal, first aid platform, intelligent AED device, intelligent AED outer box, central control platform, mobile terminal, AED device Internet of Things platform, navigation module, and remote guidance platform.

[0043] 10. In the second aspect of the above technical solution, in the step of building an intelligent interactive AED first aid training scenario based on interactive relationships, an intelligent interactive AED first aid training system for teaching demonstration as described in the first aspect of the present invention is used.

[0044] 11. In the first aspect of the above technical solution, the process of configuring and conducting simulated emergency response activation interaction for intelligent interactive AED emergency training includes the following steps:

[0045] S100, Emergency Parameter Configuration:

[0046] S110. First aid trainees start the first aid training system on the training configuration terminal. If the first aid training system fails to start, it will perform a self-check and then restart. After starting, a parameter configuration page will pop up. Then, it will determine whether it is the first time to start. If it is not the first time to start, the parameter configuration from the previous time will be automatically filled in. After completing the configuration, the main page will be entered.

[0047] S120, the signal transmission module transmits the configuration information to the display system through the central control platform, and the display terminal plays the corresponding scene and character animations;

[0048] S200, Simulated Emergency Response Activation:

[0049] S210. When the first aid trainee clicks the start button on the first aid training system on the training configuration terminal, the first aid dummy simulates chest pain and falls. If the first aid dummy does not fall, the system self-check is initiated and it re-enters the falling mode. The first aid platform automatically generates a first aid QR code based on the location information of the first aid dummy's fall.

[0050] The S220 signal transmission module transmits signals to the emergency dummy through the central control platform. The signals from the emergency training system and the emergency dummy are transmitted to the display system through the central control platform. The display terminal plays an animation of a patient suddenly experiencing chest pain and falling in the corresponding scenario. Subsequently, the emergency response module generates a distress QR code, which is simultaneously projected on the training configuration terminal and the display terminal to be displayed to the current emergency trainees and the observing emergency trainees.

[0051] In this specific process, step S100, emergency parameter configuration, is based on the interaction between the current emergency trainee and the training configuration terminal and the emergency training system. Based on the interaction between the training configuration terminal, the central control platform, and the display terminal, the display content corresponding to the emergency parameter information is synchronously displayed to the emergency trainee through the display terminal. Step S200, simulated emergency activation, is based on the interaction between the emergency trainee, the training configuration terminal, the emergency dummy, the emergency platform, the central control platform, and the display terminal. The display content generated by the emergency dummy simulating a fall and calling for help is synchronously displayed to the emergency trainee through the display terminal, facilitating simultaneous understanding by both the trainee performing the operation and the trainees watching on-site, further improving training quality and efficiency.

[0052] 12. In the second aspect of the above technical solution, the simulated emergency preparation interaction process for responding to distress calls and conducting intelligent interactive AED emergency training includes the following steps:

[0053] S300, Initiate a distress call:

[0054] S310. When a first aid trainee uses a mobile terminal to scan the SOS QR code on the display terminal to enter the emergency hotline mini-program and clicks the "Initiate Help" button, nearby first aid volunteers immediately receive the SOS message. If a volunteer does not receive the message, the emergency platform will resend the SOS SMS. Simultaneously, nearby smart AED devices will receive the SOS signal, and the SOS icon on the device will flash. The smart AED outer casing will receive the SOS signal, flash its emergency light, and sound an alarm to alert the user. If neither the AED nor its outer casing receives the signal, the AED device's IoT platform will initiate a self-check program and resend the signal. If the self-check fails, an alarm will be triggered, notifying maintenance personnel to investigate.

[0055] S320, the emergency response module initiates an emergency signal, and the signal transmission module transmits the signal from the emergency hotline mini-program to the display system through the central control platform. The display terminal is divided into two screens, one of which plays the one-click emergency call QR code image, and the other screen plays the animation of people dialing the 120 emergency number and scanning the emergency call QR code.

[0056] S400, Arrive at the patient's location with the equipment:

[0057] S410. After a successful SOS call, the Emergency Hotline mini-program displays the location information of the person in distress, nearby volunteers, and nearby smart AED devices. Upon receiving the SOS SMS, the emergency volunteer accesses the Emergency Hotline mini-program via a link, clicks the "Nearby AED" button, follows the navigation to the smart AED device, retrieves the device from its case, and then follows the navigation to the location of the person in distress. Similarly, the current emergency trainee clicks the "Nearby AED" button in the Emergency Hotline mini-program, follows the navigation to the smart AED device, retrieves the device from its case, and then follows the navigation to the location of the person in distress.

[0058] The S420 navigation module provides navigation services for current first aid trainees and volunteers. The signal transmission module transmits the signal from the smart AED box to the display system through the central control platform. The display terminal plays two screens: one screen shows the location map, the person in distress, the volunteer trainee, and the location of the AED; the other screen shows an animation of the first aid volunteer arriving at the location of the smart AED device and taking it out of the smart AED box, followed by an animation of the volunteer arriving at the patient's side.

[0059] In this specific process, step S300, initiating a distress call, is based on the interaction between the emergency medical trainees, the mobile terminal, the emergency medical platform, the smart AED device, and the smart AED outer casing. Step S400, delivering the device to the patient, is based on the interaction between the emergency medical trainees, the smart AED device, the central control platform, and the display terminal. Through the implementation of these steps and the interaction between various parts and personnel, the division of labor among emergency medical trainees and volunteers in this training becomes more scientific, reasonable, and clear. This allows relevant personnel to quickly grasp how to respond to distress calls, how to obtain the smart AED device, and the corresponding preparations, rapidly improving the trainees' proficiency in the relevant procedures. The process is also simultaneously displayed to the emergency medical trainees through the display terminal, facilitating simultaneous understanding by both the trainees performing the operation and those observing on-site, further enhancing the quality and efficiency of the training.

[0060] 13. In the second aspect of the above technical solution,

[0061] The process of conducting intelligent interactive AED emergency confirmation and providing remote emergency guidance includes the following steps:

[0062] S500, AED remote connection:

[0063] S510: When the first aid trainee turns on the smart AED device, the device automatically enters defibrillation mode. If it fails to enter defibrillation mode, the device is turned on again. If it fails to enter defibrillation mode again, an alarm is automatically triggered, notifying maintenance personnel to investigate. Subsequently, a "Remote Connection" reminder flashes on the screen of the smart AED device. The trainee can click on it to connect via video with an experienced first aid instructor. If the remote connection button does not flash, the system automatically checks the network connection module. If a network connection error occurs, an alarm is automatically triggered, notifying maintenance personnel to investigate.

[0064] The S520 and remote connection module ensure video calls between the emergency site and remote guidance personnel. The AED device's IoT platform obtains the AED's signal, and the signal transmission module transmits it to the display system through the central control platform. The display terminal plays two screens: one screen plays an animation of the smart AED device being turned on, followed by an animation of the "remote connection" reminder on the AED interface; the other screen plays an animation of the AED being started, followed by an animation of the smart AED device entering defibrillation mode.

[0065] S600, AED Pre-use Confirmation:

[0066] S610. After the remote connection is established, the first aid trainee should kneel in front of the patient according to the animation prompts on the screen of the smart AED device and the instructions of the remote first aid instructor. The trainee should pat the patient's shoulders with both hands and call out in the patient's ear to confirm that the patient is unconscious, not breathing, and has no pulse. If the patient is not in the above state, other methods of rescue should be carried out according to the instructions of the remote instructor.

[0067] The S620 signal transmission module transmits the video stream signal from the remote connection module to the display system through the central control platform. The display terminal plays two screens: one screen shows the video connection between the online emergency medical instructor and the other screen shows an animation of the rescuer patting the patient's shoulders and calling out in their ear.

[0068] In this specific process, steps S500 (remote AED connection) and S600 (pre-use AED confirmation) are achieved through interaction between the emergency medical trainee, the emergency dummy, the remote guidance platform, and the smart AED device. Furthermore, the interaction between the trainee, the remote guidance platform, and the display terminal demonstrates the relevant processes to both the trainee and any observing trainees. This implementation allows trainees to better understand the status of the smart AED device and the patient during emergency care. It also allows remote emergency medical personnel to participate, providing more professional guidance at emergency scenes and increasing the success rate of emergency care. This training process teaches trainees more standardized operating procedures, and the inclusion of remote guidance enables emergency personnel to conduct more accurate emergency preparation and operations. The information is also simultaneously displayed to trainees via the display terminal, facilitating simultaneous understanding by both the trainee performing the procedure and those observing, further improving training quality and efficiency.

[0069] 14. In the second aspect of the above technical solution, the process of conducting and completing the interactive first aid training for intelligent AED includes the following steps:

[0070] S700, attaching electrode pads:

[0071] S710: First aid trainees, following the animated prompts and voice prompts on the smart AED device screen, as well as the instructions from remote first aid instructors, attach the electrode pads to the patient's chest. If the system does not recognize the ECG signal after attachment, the electrode pads are reattached as prompted. If the system still fails to recognize the signal, an alarm is automatically triggered to notify maintenance personnel for troubleshooting.

[0072] S720: The identification module identifies the ECG signal of the emergency dummy. The signal transmission module transmits the signal of the emergency dummy to the display system through the central control platform. The display terminal plays two screens. One screen plays the video connection screen of the online emergency instructor. The other screen plays the animation of the rescuer moving away from the patient. In the animation, the patient's body is in a perspective state, the patient's heart is beating randomly, and the ECG waveform corresponding to the configured heart rate type is displayed.

[0073] S800, Defibrillation:

[0074] The S810 intelligent AED device automatically analyzes the patient's electrocardiogram waveform to determine if defibrillation is needed. If defibrillation is determined to be necessary, the defibrillation button indicator on the device illuminates. First aid trainees, following the animated prompts, voice prompts, and instructions from the remote first aid instructor, press the defibrillation button and then move away from the patient. The intelligent AED device then begins defibrillation. If defibrillation is not needed, it directly proceeds to cardiopulmonary resuscitation (CPR).

[0075] The S820 identification module automatically analyzes the patient's ECG waveform to determine if defibrillation is needed. The signal transmission module transmits the signals from the smart AED device and the emergency dummy to the display system through the central control platform. The display terminal plays two screens: one screen shows the video connection between the online emergency instructor and the other screen shows the patient's body in a transparent state, with an electric current passing through the patient's heart in the animation, and the selected ECG waveform is displayed to show the ECG after the shock.

[0076] S900, Cardiopulmonary Resuscitation:

[0077] S910: First aid trainees begin cardiopulmonary resuscitation (CPR) on the patient based on the animated prompts and voice prompts on the screen of the smart AED device, as well as the prompts from the remote first aid instructor. The smart AED device performs real-time assessment and analysis of the quality of CPR and provides visual and voice prompts on the screen of the smart AED device, including at least whether the compressions are too fast / too slow, too deep / too shallow, and whether the compression posture is correct.

[0078] The S920 recognition module captures and assesses the current actions of the first aid trainee. The signal transmission module transmits the signals from the smart AED device and the first aid dummy to the display system via the central control platform. The display terminal plays two screens: one screen shows the video connection between the online first aid instructor and the other screen shows the animation of the rescuer performing CPR and the specific parameters of CPR. In the animation, the patient's body is presented in a perspective state, and the patient's heart reaches different positions with the depth of compression, and the selected electrocardiogram waveform changes are displayed.

[0079] S1000, Patient awakens:

[0080] S1100, repeat steps S800 and S800 until the emergency training system issues a wake-up signal, the patient wakes up, and the emergency treatment process ends;

[0081] The S1200 signal transmission module transmits the awakening signal to the display system through the central control platform, and the display terminal plays an animation of the patient's awakening.

[0082] In this specific process, steps S700 (attaching electrode pads), S800 (defibrillation), and S900 (cardiopulmonary resuscitation) are all completed through the interaction between the current emergency medical trainee and the emergency dummy, the remote guidance platform, and the smart AED device, as well as the interaction between the emergency medical trainee, the remote guidance platform, and the display terminal. When performing step S700 (attaching electrode pads), the smart AED device and the prompts from the remote emergency medical instructor guide the current emergency medical trainee to accurately attach the electrode pads to the correct position on the patient's (emergency dummy's) chest. The relevant correct animation and corresponding data are displayed on the display terminal, allowing the current emergency medical trainee and other trainees to receive feedback on the implementation of this step simultaneously, thereby improving the training effect. During the defibrillation and CPR training, the interaction between the trainees, the emergency medical personnel, the remote guidance platform, and the smart AED device allows trainees to more accurately master these techniques. Defibrillation and CPR are among the most important and essential skills in emergency medical training. Through various interactive elements, the training process includes real-time demonstrations of the procedures on a large screen, linked to the trainees' own defibrillation and CPR practice. This helps trainees learn the procedures more quickly and effectively, allowing them to immediately assess the correctness of their actions and making the training more efficient and convenient. Experienced emergency medical personnel can also provide remote, real-time guidance, improving the training effect and ensuring trainees' actions are more scientific and standardized. The training is also simultaneously displayed on a terminal, allowing both trainees practicing and those observing to learn concurrently, further enhancing training quality and efficiency.

[0083] Due to the application of the above-mentioned solution, the present invention has the following advantages and effects compared with the prior art:

[0084] 1. By implementing the technical solution of this invention, the existing AED emergency training programs address the problems of lack of interaction among trainees, lack of interaction between the AED user (trainee), patient (rescue dummy), and defibrillator, as well as lack of remote guidance interaction. An innovative intelligent interactive AED emergency training system and method with more complete and effective intelligent interaction and corresponding factual feedback for teaching demonstrations is designed. This intelligent interactive AED emergency training system and method utilizes multiple interactive relationships between various devices and personnel to complete the entire intelligent interactive AED emergency training process.

[0085] 2. Through the implementation of the technical solution of this invention, trainees can simulate real-life scenarios and use the emergency call function of the emergency rescue platform to notify emergency volunteers immediately. They can also quickly find the nearest AED device through the navigation function of the emergency rescue platform. Animations of each emergency rescue step are displayed in real time on the large screen, which is linked with the trainees' operations. This helps trainees learn the emergency rescue process more quickly and effectively. Other trainees watching on-site can also learn more intuitively and synchronously. The recognition module on the smart AED device can be used to analyze AED and CPR data in real time without the need for additional cameras or CPR feedback devices to collect data on the emergency rescue process.

[0086] 3. Through the implementation of the technical solution of this invention, and by conducting remote video calls through a remote guidance platform, trainees can have remote video calls with experienced first aid instructors during the training process, and receive real-time guidance on their first aid operations. Based on the real-time interaction and feedback functions, the system provides real-time feedback on each step of the trainee's operation, allowing trainees to understand in a timely manner whether their operation is correct, making the training more efficient and convenient.

[0087] 4. In summary, the richer, more practical, and more efficient interactive relationships and mutual reliance in this intelligent interactive AED first aid training system make the training process more closely resemble real-world scenarios and better suited to trainees with varying levels of proficiency in different first aid skills. This results in high-quality instruction, allowing trainees to more intuitively understand whether their first aid actions are standardized and receive timely feedback. It also enables other trainees to participate in the intelligent interactive AED first aid training simultaneously through the display terminal, avoiding the predicament of a single system being used by only one trainee. This significantly improves the training needs of a batch of trainees while saving on venue and equipment costs. Attached Figure Description

After analyzing the received signals, the intelligent AED device determines whether the emergency rescue dummy meets the discharge conditions.

[0132] In Embodiment 1 of the present invention, the ECG recognition module performs filtering preprocessing on the ECG signal received by the intelligent AED device, and then performs amplitude detection to determine whether it is a cardiac arrest signal.

[0136] The emergency rescue platform is equipped with an emergency hotline mini-program, which sends distress messages to nearby emergency volunteers, smart AEDs, and smart AED boxes.

[0137] In Embodiment 1 of the present invention, the data transmission between the central control console and the emergency training system, the display system, and the emergency platform adopts the HTTP protocol; the data transmission between the intelligent AED device and the AED device IoT platform and the central control platform adopts the MQTT protocol; and the data transmission between the intelligent AED outer box and the central control platform adopts the AMQP protocol.

[0138] In Embodiment 1 of the present invention, the intelligent interactive AED first aid training system further includes a data storage module. The data storage module is used to store the operation data and training records implemented during the interaction between the current first aid trainee and the first aid dummy, training configuration terminal, display terminal, first aid platform, intelligent AED device, intelligent AED outer box, central control platform, mobile terminal, AED device Internet of Things platform, navigation module, and remote guidance platform.

[0139] The following example, using a tablet computer as the training terminal and a large TV screen as the demonstration terminal, will be used to explain in detail the specific composition and functions of the intelligent interactive AED first aid training system used for teaching demonstration in this embodiment of the invention.

[0140] like Figure 1As shown, the intelligent interactive AED first aid training system in this embodiment of the invention consists of hardware devices for interaction, system modules for interaction, and sub-modules in the hardware and system.

[0141] The hardware devices used for interaction include a tablet computer (configuration terminal), a smart AED device, a smart AED case, a first-aid dummy, and a large TV screen (display terminal). Among them:

[0142] Tablet PC (configuration terminal): Used to set first aid training parameters, such as scenario, person characteristics, heart rhythm type, etc., and to control the demonstration process.

[0143] Smart AED devices: AED devices with functions such as reminders, navigation, and rescue guidance, equipped with a touch screen, and interact with users through the interface.

[0144] Smart AED outer case: Used to store smart AED devices, with reminder and location functions, and alerts users through sound and light.

[0145] Emergency mannequin: Used to simulate patient falls and cardiac abnormalities, using sensors to recognize the user's action of attaching electrode pads.

[0146] Large TV screen (display terminal): Displays real-time animations of emergency procedures and CPR parameters.

[0147] The interactive system includes a tablet app (first aid training system), a large-screen TV app (display system), and an emergency hotline mini-program. Among them:

[0148] Tablet app (configuration system): Interacts with users through a user interface, including server-side and client-side components.

[0149] TV large-screen app (display system): Includes server and client, automatically plays corresponding first aid operation animations based on the device signal, providing visual feedback for trainees.

[0150] Emergency Call Mini Program (Emergency Call System): Used to initiate a distress signal and promptly send the distress information to volunteers, smart AED boxes, and AED devices near the distress location.

[0151] The hardware and system submodules include a signal transmission module, a device data acquisition and control module, an emergency response module, a navigation module, an identification module, a remote connection module, and a data storage module; among which:

[0152] The equipment data acquisition and control module includes:

[0153] AED Device IoT Platform: Collects real-time action information of AED devices and AED boxes, and receives instructions from the central control platform to send to the devices, thereby controlling the device functions;

[0154] The emergency response module includes:

[0155] First Aid QR Code Generation Module: When the first aid training begins and the first aid dummy falls to the ground, the terminal application (tablet app) obtains the user's current location and sends a request to the server. The server creates a unified first aid event, records the personal information and geographical location of the person seeking help, and each first aid event has a unique ID. The QR code generated through the first aid ID is the first aid QR code.

[0156] SOS module: Users scan a QR code with their mobile phones to enter the emergency hotline mini-program. The terminal application will parse the QR code to obtain the emergency ID and request the server to query the emergency event details corresponding to the emergency ID, including the information of the person seeking help and the geographical location.

[0157] Emergency Call Mini Program: The Emergency Call Mini Program communicates with the server via HTTP through LTE or WIFI to send distress messages to nearby emergency volunteers, smart AEDs, and smart AED boxes; the smart AED boxes communicate with the server via HTTP and AMQP protocols through LTE or WIFI, and the AED devices communicate with the server via MQTT through LTE or WIFI.

[0158] The navigation module includes:

[0159] Based on the location information of the person seeking help, volunteers, and the AED, the terminal (Emergency Line Mini Program) guides the user to the shortest path to the AED device and the location of the emergency call.

[0160] The recognition module includes:

[0161] Electrode recognition module: The dummy has a built-in ECG signal generator as a simulator, which can output three types of electrical signals: ventricular fibrillation heart rate, normal heart rate, and cardiac arrest heart rate. The ECG signal generator consists of a digital signal processor, a digital-to-analog converter, a signal conditioning circuit, an electrode interface, and a power supply module. When the electrode pads are attached to the dummy, the simulator periodically emits electrical pulses of a specified form, which are conducted through wires, conductive patches, and electrode pads to be received by the defibrillator. The defibrillator analyzes the received signals to determine whether the dummy meets the discharge conditions.

[0162] ECG recognition module: The ECG signal undergoes internal filtering and preprocessing, followed by amplitude detection to determine if it is a cardiac arrest signal. If it is, further processing is stopped, indicating a non-shockable rhythm. Otherwise, the algorithm extracts features such as heart rate, QRS width, waveform slope, and complexity. Based on the feature vector, a decision is made. If the feature vector meets the criteria for ventricular fibrillation or rapid ventricular tachycardia, the rhythm is determined to be shockable, prompting defibrillation treatment; otherwise, it is determined to be a non-shockable rhythm. The cardiac rhythm analysis algorithm continuously identifies the patient's heart rhythm throughout the treatment process, ensuring accurate and safe treatment.

[0163] Cardiopulmonary resuscitation (CPR) recognition module: Uses optical sensors to capture video footage during CPR and utilizes machine vision technology to analyze compression actions, including compression posture, compression depth, compression frequency, and number of compressions.

[0164] The remote connection module includes:

[0165] When an AED terminal initiates a remote guidance request, the server creates an instant messaging room. After the AED terminal enters the room, it captures video through its camera and audio through its microphone, and pushes the audio and video streams to the instant messaging room in real time. Volunteers in the room push the streams in the same way through their terminals. Volunteers can pull and play the AED audio and video streams, which means the audio and video from the AED terminal are played in real time, and the AED terminal can pull and play the audio and video streams from the volunteers, which means the audio and video from the volunteers are played in real time.

[0166] The data storage module includes:

[0167] It stores user operation data and training records, and provides data analysis functions to evaluate training effectiveness.

[0168] Example 2: This invention proposes an intelligent interactive AED first aid training method for teaching demonstrations, the intelligent interactive AED first aid training method comprising:

[0169] To build an intelligent interactive AED first aid training scenario based on interactive relationships, an interactive relationship must be established between at least two or more of the following: first aid trainees, first aid instructors, training configuration terminals, first aid training systems, display terminals, display systems, mobile terminals, first aid platforms, first aid dummies, intelligent AED devices, intelligent AED outer boxes, central control platforms, and remote guidance platforms. The intelligent interactive AED first aid training scenario is built from the above interactive relationships, where first aid trainees include current first aid trainees and observing first aid trainees.

[0170] Configure and conduct simulated emergency response activation interaction for intelligent interactive AED emergency training. Based on the interaction between the emergency trainee and the training configuration terminal and emergency training system, emergency parameters are configured. Based on the interaction between the training configuration terminal, central control platform, and display terminal, the display content corresponding to the emergency parameter information is synchronously displayed to the emergency trainee through the display terminal. Based on the interaction between the emergency trainee, training configuration terminal, emergency dummy, emergency platform, central control platform, and display terminal, the display content corresponding to the emergency dummy's simulated fall and distress call information is generated and synchronously displayed to the emergency trainee through the display terminal.

[0171] This simulated emergency preparedness interaction system, designed for responding to distress calls and providing intelligent interactive AED first aid training, involves interaction between the trainee, mobile terminal, emergency platform, intelligent AED device, and intelligent AED case. The trainee receives and responds to distress calls via mobile terminal and intelligent AED case. The interaction between the emergency platform, central control platform, and display terminal simultaneously displays the process of responding to the distress call to the trainee. Finally, the interaction between the trainee, intelligent AED device, central control platform, and display terminal also simultaneously displays the corresponding information after the trainee arrives at the patient's location with the intelligent AED device.

[0172] The system enables intelligent interactive AED emergency confirmation and remote emergency guidance interaction. Based on the interaction between the emergency trainee, the emergency dummy, the remote guidance platform, and the intelligent AED device, the current emergency trainee turns on the intelligent AED device, which connects to the remote guidance platform. The current emergency trainee monitors the status of the emergency dummy based on the alerts from the intelligent AED device and the prompts from the remote emergency guide. Based on the interaction between the emergency trainee, the remote guidance platform, and the display terminal, the corresponding display content of the current intelligent interactive AED emergency and remote emergency guidance interaction is synchronously displayed to the emergency trainee through the display terminal.

[0173] The interactive AED first aid training program involves the trainee interacting with a first aid dummy, a remote guidance platform, and the AED device. The trainee attaches the AED's electrodes to the dummy's chest. The AED automatically analyzes and determines that defibrillation is possible. The trainee then uses the AED and / or the remote guidance platform to perform defibrillation. If defibrillation is not needed, the trainee performs CPR as instructed by the AED and / or the remote guidance platform until the first aid is complete. Based on the interaction between the trainee, the remote guidance platform, and the display terminal, the corresponding content is simultaneously displayed to the trainee via the display terminal.

[0174] The following describes Embodiment 2 of the present invention in more detail with reference to one of the preferred embodiments.

[0175] The preferred embodiment of the intelligent interactive AED first aid training method for educational demonstrations includes, as follows: Figure 2 The following detailed steps are shown.

[0176] To build an intelligent interactive AED first aid training scenario based on interactive relationships, an interactive relationship must be established between at least two or more of the following: first aid trainees, first aid instructors, training configuration terminals, first aid training systems, display terminals, display systems, mobile terminals, first aid platforms, first aid dummies, intelligent AED devices, intelligent AED outer boxes, central control platforms, and remote guidance platforms. The intelligent interactive AED first aid training scenario is built from the above interactive relationships, where first aid trainees include current first aid trainees and observing first aid trainees.

[0177] S010: In the step of building an intelligent interactive AED first aid training scenario based on interactive relationships, the intelligent interactive AED first aid training system for teaching demonstration as described in Embodiment 1 of the present invention is used.

[0178] The process of configuring and conducting simulated emergency response activation interaction for intelligent interactive AED first aid training includes the following steps:

[0179] S100, Emergency Parameter Configuration:

[0180] S110. First aid trainees start the first aid training system on the training configuration terminal. If the first aid training system fails to start, it will perform a self-check and then restart. After starting, a parameter configuration page will pop up. Then, it will determine whether it is the first time to start. If it is not the first time to start, the parameter configuration from the previous time will be automatically filled in. After completing the configuration, the main page will be entered.

[0181] The S120 signal transmission module transmits configuration information to the display system through the central control platform. The display terminal plays animations of the corresponding scenes and characters, making it easy for both the trainees performing the operation and those watching on-site to grasp the information simultaneously.

[0182] S200, Simulated Emergency Response Activation:

[0183] S210. When the first aid trainee clicks the start button on the first aid training system on the training configuration terminal, the first aid dummy simulates chest pain and falls. If the first aid dummy does not fall, the system self-check is initiated and it re-enters the falling mode. The first aid platform automatically generates a first aid QR code based on the location information of the first aid dummy's fall.

[0184] The S220 signal transmission module transmits signals to the emergency dummy through the central control platform. The signals from the emergency training system and the emergency dummy are transmitted to the display system through the central control platform. The display terminal plays an animation of a patient suddenly experiencing chest pain and falling in the corresponding scenario. Subsequently, the emergency response module generates a distress QR code, which is simultaneously projected on the training configuration terminal and the display terminal to be displayed to the current emergency trainees and the observing emergency trainees.

[0185] The simulated emergency preparedness process, which involves responding to distress calls and conducting intelligent interactive AED first aid training, includes the following steps:

[0186] S300, Initiate a distress call:

[0187] S310. When a first aid trainee uses a mobile terminal to scan the QR code on the display terminal to enter the emergency hotline mini-program and clicks the "Initiate Help" button, nearby first aid volunteers will immediately receive the distress message; at the same time, nearby smart AED devices will also receive the distress signal and sound an alarm, and the smart AED outer box will receive the distress signal and sound an alarm.

[0188] S320, the emergency response module initiates an emergency signal, and the signal transmission module transmits the signal from the emergency hotline mini-program to the display system through the central control platform. The display terminal is divided into two screens, one of which plays the one-click emergency call QR code image, and the other screen plays the animation of people dialing the 120 emergency number and scanning the emergency call QR code.

[0189] S400, Arrive at the patient's location with the equipment:

[0190] S410. After a successful emergency call, the Emergency Line mini-program displays the location information of the emergency call, the location information of nearby volunteers, and the location information of nearby smart AED devices. After receiving the emergency information, the emergency volunteers and the current emergency trainees enter the Emergency Line mini-program through the link, click the nearby AED button, and assign one of them to go to the smart AED device according to the navigation. After taking the smart AED device from the smart outer box, they go to the location of the emergency call according to the navigation.

[0191] The S420 navigation module provides navigation services for current first aid trainees and volunteers. The signal transmission module transmits the signal from the smart AED box to the display system through the central control platform. The display terminal plays two screens: one screen shows the location map, the person in distress, the volunteer trainee, and the location of the AED; the other screen shows an animation of the first aid volunteer arriving at the location of the smart AED device and taking it out of the smart AED box, followed by an animation of the volunteer arriving at the patient's side.

[0192] The process of conducting intelligent interactive AED emergency confirmation and providing remote emergency guidance includes the following steps:

[0193] S500, AED remote connection:

[0194] S510: When the first aid trainee turns on the smart AED device, the smart AED device automatically enters defibrillation mode; then the screen of the smart AED device flashes a "remote connection" reminder, and the first aid trainee can click on it to connect with a first aid instructor with first aid experience via video.

[0195] The S520 and remote connection module ensure video calls between the emergency site and remote guidance personnel. The AED device's IoT platform obtains the AED's signal, and the signal transmission module transmits it to the display system through the central control platform. The display terminal plays two screens: one screen plays an animation of the smart AED device being turned on, followed by an animation of the "remote connection" reminder on the AED interface; the other screen plays an animation of the AED being started, followed by an animation of the smart AED device entering defibrillation mode.

[0196] S600, AED Pre-use Confirmation:

[0197] S610. After the remote connection is established, the first aid trainee should kneel in front of the patient according to the animation prompts on the screen of the smart AED device and the instructions of the remote first aid instructor. The trainee should pat the patient's shoulders with both hands and call out in the patient's ear to confirm that the patient is unconscious, not breathing, and has no pulse. If the patient is not in the above state, other methods of rescue should be carried out according to the instructions of the remote instructor.

[0198] The S620 signal transmission module transmits the video stream signal from the remote connection module to the display system through the central control platform. The display terminal plays two screens: one screen shows the video connection between the online emergency medical instructor and the other screen shows an animation of the rescuer patting the patient's shoulders and calling out in their ear.

[0199] The process of conducting and completing the interactive first aid training for intelligent AEDs includes the following steps:

[0200] S700, attaching electrode pads:

[0201] S710: First aid trainees should place the electrode pads on the patient's chest according to the animated reminders and voice prompts on the screen of the smart AED device, as well as the prompts from the remote first aid instructor. If the system does not recognize the ECG signal after placement, the electrode pads should be re-placed according to the prompts.

[0202] The S720 identification module identifies the ECG signal of the emergency dummy. The signal transmission module transmits the emergency dummy's signal to the display system through the central control platform. The display terminal plays two screens: one screen shows the video connection between the online emergency instructor and the other screen shows the rescuer making movements away from the patient.

[0203] S800, Defibrillation:

[0204] The S810 intelligent AED device automatically analyzes the patient's electrocardiogram waveform to determine if defibrillation is needed. If defibrillation is determined to be necessary, the defibrillation button light on the device illuminates. The first aid trainee, following the prompts on the intelligent AED device screen and the instructions from the remote first aid instructor, presses the defibrillation button, then moves away from the patient. The intelligent AED device then begins defibrillation. If defibrillation is not needed, it directly proceeds to cardiopulmonary resuscitation (CPR).

[0205] The S820 identification module automatically analyzes the patient's ECG waveform to determine if defibrillation is needed. The signal transmission module transmits the signals from the smart AED device and the emergency dummy to the display system through the central control platform. The display terminal plays two screens: one screen shows the video connection between the online emergency instructor and the other screen shows the patient's body in a transparent state, with an electric current passing through the patient's heart in the animation, and the selected ECG waveform is displayed to show the ECG after the shock.

[0206] S900, Cardiopulmonary Resuscitation:

[0207] S910. First aid trainees begin cardiopulmonary resuscitation (CPR) on the patient based on the prompts on the smart AED device screen and the prompts from the remote first aid instructor. The smart AED device performs real-time assessment and analysis of the quality of CPR and provides reminders on the smart AED device screen that include at least the following: pressing too fast / too slow, pressing too deep / too shallow, and whether the pressing posture is correct.

[0208] The S920 identification module captures and assesses the current actions of the first aid trainee. The signal transmission module transmits the signals from the smart AED device and the first aid dummy to the display system through the central control platform. The display terminal plays two screens: one screen shows the video connection between the online first aid instructor and the other screen shows the animation of the rescuer performing CPR and the specific parameters of CPR.

[0209] S1000, Patient awakens:

[0210] S1100, repeat steps S800 and S800 until the emergency training system issues a wake-up signal, the patient wakes up, and the emergency treatment process ends;

[0211] The S1200 signal transmission module transmits the awakening signal to the display system through the central control platform, and the display terminal plays an animation of the patient's awakening.

[0212] Below, again using a tablet computer as the training terminal (the first aid training system is a tablet app) and a large TV screen as the demonstration terminal (the demonstration system is a large TV screen app) as an example, we will explain in detail the specific implementation steps of the intelligent interactive AED first aid training method used for teaching demonstration in this embodiment of the invention, combined with more specific processes and interactive relationships.

[0213] A smart, interactive AED first aid training method for educational demonstrations, comprising the following steps:

[0214] S010: In the step of building an intelligent interactive AED first aid training scenario based on interactive relationships, the intelligent interactive AED first aid training system for teaching demonstration as described in Embodiment 1 of the present invention is used.

[0215] S100, Emergency Parameter Configuration.

[0216] First, the first aid trainee opens the first aid training app on the tablet. If the app fails to start, it will perform a self-check and then restart. After starting, a parameter configuration page will pop up, and it will then determine whether it is the first time to start. If it is not the first time to start, it will automatically fill in the parameter configuration from the previous time. After completing the configuration, the trainee will enter the main page.

[0217] The specific configuration parameters should include at least one or more combinations of the contents in Table 1 below:

[0218]

[0219] Table 1

[0220] The S120 signal transmission module transmits configuration information to the TV app via the central control platform. The corresponding scene and character animations are then played on the large TV screen, allowing both the trainees performing the operation and those watching on-site to grasp the information simultaneously.

[0221] For the detailed process of step S100, please refer to [link / reference]. Figure 5 As shown, the system module interaction in step S100 can be referred to Figure 6 As shown.

[0222] S200, simulated emergency response activated.

[0223] S210: First aid trainees click the start button on the tablet first aid training app. A dummy simulates chest pain and falls. If the dummy does not fall, the system self-checks and re-enters the fall mode. The first aid platform automatically generates a first aid QR code based on the dummy's fall location information.

[0224] The S220 and signal transmission module transmit signals to the dummy through the central control platform. The signals from the tablet app and the dummy are transmitted to the TV app through the central control platform. An animation of the patient suddenly experiencing chest pain and falling in the corresponding scenario is played on the TV screen. Then, the emergency response module generates a distress QR code, which is simultaneously projected on the tablet and the TV screen for easy scanning by everyone on site.

[0255] For the detailed process of step S1000, please refer to [link / reference]. Figure 19 As shown, the system module interaction in step S1000 can be referred to Figure 20 As shown.

[0256] Through the implementation of the above embodiments, and through the realization and mutual reliance of richer, more practical, and more efficient interactive relationships in the intelligent interactive AED first aid training system, the training process becomes more closely aligned with actual scenarios and more suitable for high-quality teaching for trainees with varying levels of proficiency in different first aid skills. First aid trainees can more intuitively understand whether their current first aid actions are standardized and receive timely feedback. It also allows other trainees to participate in the intelligent interactive AED first aid training simultaneously through the display terminal, avoiding the predicament that a single intelligent interactive AED first aid training system can only be used by one current first aid trainee. This significantly improves the training needs of a batch of first aid trainees, saves on venue and equipment costs, and solves the problems of lack of interaction among trainees, lack of interaction between the AED implementer (trainee), patient (first aid dummy), and defibrillator, and lack of remote guidance interaction in existing AED first aid training, thus achieving the purpose of this invention.

They should not be construed as limiting the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
