Description

Technical Field

[0001] The present invention relates to the technical field of cardiopulmonary resuscitation, and in particular to an intelligent interactive AED first aid training system and method for teaching demonstration. Background Art

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

[0003] In the early stage of cardiac arrest, 85% to 90% of patients suffer from ventricular fibrillation. The most effective way to treat ventricular fibrillation is to use AED (Automated External Defibrillator) defibrillation as soon as possible. After ventricular fibrillation occurs, the most effective defibrillation is within 3-5 minutes. For every minute of defibrillation delay, the survival rate decreases by 7% to 10%. About 540,000 people die from cardiac arrest in my country every year. Placing AED emergency equipment in public places is an important measure to reduce sudden death from cardiac arrest. AED external defibrillation is an important step in CPR (Cardio Pulmonary Resuscitation). The person who uses AED is the implementer of AED CPR (hereinafter referred to as the implementer), and the person who receives AED external defibrillation is the recipient of AED CPR (hereinafter referred to as the patient).

[0004] At present, AED has been widely used in public places outside hospitals to rescue patients with sudden cardiac arrest in a timely manner. Since AED equipment is a professional device related to the life safety of patients, it usually requires implementers who have undergone frequent basic life support training and professional medical staff to perform first aid operations. However, the public's lack of understanding of AED use and first aid knowledge leads to low first aid efficiency. Therefore, it is necessary to develop an intelligent interactive AED first aid training system and related technologies for teaching to improve the public's first aid awareness and skills.

[0005] In the process of implementing the present invention, the applicant found that the prior art still has at least the following problems in the solution for AED first aid training: 1. The current AED first aid training usually only teaches one student. There are usually more than one students in AED first aid training. The lack of interaction among students during the teaching process leads to increased learning time and cost during the training process.

[0006] 2. In the current AED first aid training process, there is a lack of interaction between the AED implementer (trainee), the patient (first aid dummy), and the defibrillator. Trainees cannot more intuitively know whether the actions of the currently operated equipment, the actions during radial cardiopulmonary resuscitation, and the relevant signal parameters of the patient itself are correct, and relevant linkages cannot be made, resulting in poor learning effects of first aid training.

[0007] 3. In the current AED first aid training process, usually only the implementers (trainees) are trained on the application of patients (first aid dummies) and defibrillator equipment. With the establishment of the existing AED first aid platform, the remote guidance of first aid instructors on the first aid platform has emerged in the process of using AED equipment. The existing AED first aid training system is lacking in this aspect.

[0008] Therefore, how to solve the problems existing in the above-mentioned AED first aid training process has become the subject to be studied and solved by the present invention. Summary of the invention

[0019] The navigation module is used to guide the rescuers and volunteers to the shortest path to the AED equipment and the rescue location based on the location information of the rescuers, volunteers and the AED equipment.

[0020] The remote guidance platform is a device that provides audio and video communication for the first aid trainees and first aid instructors themselves according to the remote guidance request sent by the intelligent AED device.

[0021] The central control platform is used to receive and forward signals and instructions from various devices and systems in real time.

[0025] The simulated first aid preparation interaction for responding to distress messages and conducting intelligent interactive AED first aid training is based on the interaction among the current first aid trainee, mobile terminal, first aid platform, intelligent AED device, and intelligent AED outer box. The current first aid trainee obtains the distress message and responds through the mobile terminal and the intelligent AED outer box. Based on the interaction among the first aid platform, the central control platform, and the display terminal, the process of responding to the distress message is synchronously displayed to the first aid trainee through the display terminal; based on the interaction among the first aid trainee, the intelligent AED device, the central control platform, and the display terminal, the display content corresponding to the current first aid trainee carrying the intelligent AED device to the patient's location after responding to the distress message is synchronously displayed to the first aid trainee through the display terminal.

[0026] Carry out intelligent interactive AED first aid confirmation and remote first aid guidance interaction, based on the interaction between the first aid trainee and the first aid dummy, the remote guidance platform, and the intelligent AED device. The current first aid trainee turns on the intelligent AED device, and the intelligent AED device connects to the remote guidance platform. The current first aid trainee follows the reminder of the intelligent AED device and the prompt of the remote first aid instructor to check the status of the first aid dummy; based on the interaction between the first aid trainee, the remote guidance platform, and the display terminal, the display content corresponding to the current intelligent interactive AED first aid and remote first aid guidance interaction is synchronously displayed to the first aid trainee through the display terminal.

[0027] Conduct and complete the first aid implementation interaction of the intelligent interactive AED first aid training, the current first aid student interacts with the first aid dummy, the remote guidance platform, and the intelligent AED device. The current first aid student sticks the electrode sheets of the intelligent AED device on the chest of the first aid dummy. After the intelligent AED device automatically analyzes and determines that defibrillation is possible, the current first aid student operates the intelligent AED device to perform defibrillation according to the prompts of the intelligent AED device and / or the remote guidance platform. If it is determined that defibrillation is not necessary, perform cardiopulmonary resuscitation according to the prompts of the intelligent AED device and / or the remote guidance platform until the first aid is completed; based on the interaction between the first aid student, the remote guidance platform, and the display terminal, the display content corresponding to the current first aid implementation interaction is synchronously displayed to the first aid student through the display terminal.

[0028] The relevant contents of the present invention are explained as follows: 1. Through the implementation of the above technical solutions of the present invention, in view of the lack of interaction between trainees, the lack of interaction between AED implementers (trainees), patients (first aid dummies), and defibrillators, and the lack of remote guidance interaction in the existing AED first aid training, an innovative intelligent interactive AED first aid training system and method for teaching demonstration with more complete and effective intelligent interaction and corresponding fact feedback is designed. In the intelligent interactive AED first aid training system and method, multiple interactive relationships formed by two or more of multiple devices and personnel are used to complete the whole process of intelligent interactive AED first aid training. Trainees can simulate real scenes, use the emergency call function of the first aid platform, notify first aid volunteers at the first time, and quickly find the nearest AED device through the navigation function of the first aid platform. The animation of each first aid step is demonstrated on the large screen in real time along with the entire first aid process, which is linked with the trainee's operation to help the trainee learn the first aid process more quickly and effectively, and other trainees watching on site can also learn synchronously more intuitively. The recognition module on the intelligent AED device is used to analyze AED and cardiopulmonary resuscitation data in real time. Analysis, no additional camera or CPR feedback device is needed to collect data on the first aid process. At the same time, remote video calls are made through the remote guidance platform. During the training process, remote video calls are made with experienced first aid instructors to guide the trainees' first aid operations in real time. According to the functions of real-time interaction and real-time feedback, the system has real-time feedback on each step of the trainees' operations. Trainees can promptly understand whether their operations are correct, making the training more efficient and convenient. The realization and mutual support of richer, more practical and efficient interactive relationships in the above intelligent interactive AED first aid training system make the training process more in line with the actual scene, and more in line with a high-quality teaching for trainees with different levels of mastery of various first aid skills during the training process. First aid trainees can more intuitively know whether the current first aid actions are standardized and get timely feedback. It also enables other trainees to participate in the intelligent interactive AED first aid training through the display terminal at the same time, avoiding the dilemma that a set of intelligent interactive AED first aid training systems can only be used by one current first aid trainee, greatly improving the training needs of a batch of first aid trainees, and saving site costs and equipment costs.

After analyzing the received signal, the intelligent AED device determines whether the first aid dummy meets the discharge conditions.

[0033] 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 an asystole signal. If it is an asystole signal, no further processing is performed and it is a non-shockable 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 fast ventricular tachycardia, it is determined to be a shockable rhythm and the patient is prompted to receive defibrillation treatment. Otherwise, it is determined to be a non-shockable rhythm. The patient's heart rhythm is continuously identified throughout the entire rescue process.

[0034] 7. In the first aspect of the above technical solution, the emergency platform includes an emergency response module, and the emergency response module includes an emergency QR code generation module, a call for help module, and an emergency hotline applet; The first aid QR code generation module is used to generate a first aid QR code according to the personal information and geographic information recorded in the first aid event in response to the first aid dummy simulating a fall; The call module is used to be responded to by the user holding the mobile terminal, and the response method at least includes using the mobile terminal to scan the emergency QR code to query the corresponding emergency event details, and the user responds to the reminder function of the AED outer box to learn the details of the emergency event; The first aid platform is provided with a corresponding first aid express applet, which sends a distress message to nearby first aid volunteers, smart AEDs, and smart AED boxes.

[0037] 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, the intelligent interactive AED first aid training system for teaching demonstration as described in the first aspect of the present invention is used.

[0038] 11. In the first aspect of the above technical solution, in the process of configuring and performing the simulated first aid start interaction of the intelligent interactive AED first aid training, the following steps are included: S100, first aid parameter configuration: S110, the first aid trainee starts the first aid training system on the training configuration terminal. If the first aid training system fails to start successfully, it will perform a self-check and then restart. After starting, a parameter configuration page will pop up, and then it will be determined whether it is the first start. If it is not the first start, the last parameter configuration will be automatically filled in, and the main page will be entered after the configuration is completed; 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 animation; S200, simulated first aid start: S210, the first aid trainee clicks the start button on the first aid training system of the training configuration terminal, and the first aid dummy simulates chest pain and then falls. If the first aid dummy does not fall to the ground, the system self-check is started and the fall mode is re-entered; the first aid platform automatically generates a first aid QR code according to the position information of the first aid dummy falling to the ground; S220, the signal transmission module transmits the signal to the first aid dummy through the central control platform, and the signals of the first aid training system and the first aid dummy are transmitted to the display system through the central control platform. The display terminal plays an animation of a patient suddenly suffering from chest pain and falling down in a corresponding scenario, and then the first aid response module generates a QR code for help, which is projected on the training configuration terminal and the display terminal at the same time to be displayed to the current first aid trainees and the bystander first aid trainees.

[0039] In this specific step, step S100 first aid parameter configuration is based on the interaction between the current first aid student and the training configuration terminal and the first aid training system to perform first aid parameter configuration, and based on the interaction between the training configuration terminal, the central control platform and the display terminal, the display content corresponding to the first aid parameter information is synchronously displayed to the first aid student through the display terminal; step S200 simulated first aid initiation is based on the interaction between the first aid student, the training configuration terminal, the first aid dummy, the first aid platform, the central control platform and the display terminal to synchronously display the display content corresponding to the distress call information generated by the first aid dummy simulating falling to the ground to the first aid student through the display terminal, so as to facilitate the students who are operating and the students who are watching on site to master it synchronously, thereby further improving the training quality and training efficiency.

[0040] 12. In the second aspect of the above technical solution, in the process of responding to the distress message and conducting the simulated first aid preparation interaction of the intelligent interactive AED first aid training, the following steps are included: S300, initiate a call for help: S310. The current first aid student uses a mobile terminal to scan the distress QR code on the display terminal to enter the emergency express applet, click the initiate help button, and then the nearby first aid volunteers will immediately receive the distress message. If the volunteers do not receive it, the first aid platform will resend the distress message. At the same time, the nearby smart AED device will also receive the distress signal and the SOS sign on the device will flash to alarm. The smart AED outer box will receive the distress signal and flash the emergency light while sounding a prompt tone to remind you to call for help. If the AED and the outer box do not receive the signal, the AED device IoT platform will start the device self-test program and resend the signal. If the self-test fails, the device alarm will be initiated to notify the operation and maintenance personnel to check; S320: The emergency response module initiates an emergency signal, and the signal transmission module transmits the signal of the emergency express applet to the display system through the central control platform. The display terminal is divided into two screens, one of which plays a one-key emergency QR code image, and the other plays an animation of a person dialing 120 emergency number and scanning the emergency QR code; S400, bring the equipment to the patient: S410. After the call for help is successfully initiated, the emergency line applet 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 call SMS, the emergency volunteer enters the emergency line applet through the link, clicks the nearby AED button, goes to the smart AED device according to the navigation, and goes to the emergency location according to the navigation after taking the smart AED device from the smart outer box; the current emergency trainee clicks the nearby AED button in the emergency line applet, goes to the smart AED device according to the navigation, and goes to the emergency location according to the navigation after taking the smart AED device from the smart AED outer box; S420, the navigation module provides navigation services for the current first aid students and first aid volunteers. The signal transmission module transmits the signal of the smart AED outer box to the display system through the central control platform. The display terminal plays two pictures, one of which plays the location map, the person in need of help, the volunteer students, and the AED location. The other screen plays the animation of the first aid volunteer arriving at the location of the smart AED device and taking the smart AED device out of the smart AED outer box, and then plays the animation of the volunteer arriving at the patient.

[0041] In this specific step, step S300 initiates a call for help based on the interaction of the current first aid trainee, mobile terminal, first aid platform, smart AED device, and smart AED outer box. Step S400 carries the device to the patient based on the interaction of the first aid trainee, smart AED device, central control platform, and display terminal. Through the specific implementation of the above steps and the interaction between various parts and personnel, the division of labor among first aid trainees and first aid volunteers in the training can be more scientific, reasonable and clear, so that relevant personnel can quickly master how to respond to calls for help, how to obtain smart AED devices and corresponding preparations in this training, and quickly improve the training personnel's mastery of relevant processes. It is also displayed to first aid trainees simultaneously through the display terminal, which is convenient for trainees who operate and trainees who watch on site to master simultaneously, and further improve the training quality and training efficiency.

[0042] 13. In the second aspect of the above technical solution, The process of conducting intelligent interactive AED first aid confirmation and remote first aid guidance interaction includes the following steps: S500, AED remote connection: S510, the current first aid trainee turns on the smart AED device, and the smart AED device automatically enters the defibrillation mode. If it does not enter the defibrillation mode, the smart AED device is turned on again. If it does not enter the defibrillation mode again, the device alarm is automatically triggered, and the operation and maintenance personnel are notified to check; then the screen interface of the smart AED device flashes a "remote connection" reminder, and the first aid trainee can connect with the first aid instructor with first aid experience through video after clicking it. If the remote connection button does not flash, the system automatically detects the network connection module. If the network connection reports an error, the device alarm is automatically triggered, and the operation and maintenance personnel are notified to check; S520, the remote connection module ensures the video call between the first aid site and the remote guidance personnel, the AED device IoT platform obtains the AED signal, the signal transmission module transmits it to the display system through the central control platform, and the display terminal plays two left and right pictures, one of which plays the animation of the smart AED device being turned on, followed by the "remote connection" reminder animation of the AED interface, and the other screen plays the animation of the AED starting up, followed by the animation of the smart AED device entering the defibrillation mode; S600, AED confirmation before use: S610. After the remote connection is established, the first aid trainee kneels in front of the patient according to the animation reminder on the screen of the smart AED device and the prompt of the remote first aid instructor, pats the patient's shoulders with both hands and shouts in the ear to confirm that the patient is unconscious, not breathing, and has no pulse. If the patient is not in the above state, other rescue methods are required according to the instructions of the remote instructor; S620. The signal transmission module transmits the video stream signal of the remote connection module to the display system through the central control platform. The display terminal plays two pictures, one of which plays the video connection picture of the online first aid instructor, and the other plays the animation of the rescuer patting the patient's shoulders and shouting in the ear.

[0043] In this specific step, step S500 AED remote connection and step S600 AED pre-use confirmation are implemented based on the interaction between the first aid trainee and the first aid dummy, the remote guidance platform, and the intelligent AED device, and the relevant process is displayed to the current first aid trainee and the bystander first aid trainee based on the interaction between the first aid trainee, the remote guidance platform, and the display terminal; the implementation of this specific step can enable the first aid trainee to better master the confirmation of the intelligent AED device status and the patient status during the first aid process, and at the same time allow remote first aid instructors to participate in the first aid, so that more professional personnel can provide remote guidance at the emergency first aid site, thereby increasing the probability of successful first aid. In this training process, first aid trainees are informed of more standardized operating procedures, and by adding remote guidance, first aid personnel can carry out more correct first aid preparations and operations. At the same time, it is also simultaneously displayed to the first aid trainees through the display terminal, which is convenient for the trainees who perform the operation and the trainees who watch on site to master it simultaneously, further improving the training quality and training efficiency.

[0044] 14. In the second aspect of the above technical solution, in the process of conducting and completing the first aid implementation interaction of the intelligent interactive AED first aid training, the following steps are included: S700, Paste electrode sheet: S710. First aid trainees stick the electrodes on the patient's chest according to the animation prompts and voice prompts on the smart AED device screen and the prompts of the remote first aid instructor. If the system does not recognize the ECG signal after sticking, they stick the electrodes again according to the prompts. If the system fails to recognize the signal again, the device will automatically trigger an alarm to notify the operation and maintenance personnel to investigate.

[0045] S720, the recognition module recognizes the ECG signal of the emergency dummy, and 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 pictures, one of which plays the video connection picture of the online emergency instructor, and the other 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 in a chaotic state, and an ECG waveform corresponding to the configured heart rate type is displayed; S800, Defibrillation: S810, the smart AED device automatically analyzes the patient's ECG waveform to see if defibrillation is needed. If defibrillation is needed, the defibrillation button on the device lights up. First aid trainees press the defibrillation button according to the animation reminders and voice prompts on the smart AED device screen, as well as the prompts of the remote first aid instructor, and then move away from the patient. The smart AED device starts defibrillation. If defibrillation is not needed, cardiopulmonary resuscitation is performed directly.

[0046] S820, the ECG recognition module in the recognition module automatically analyzes whether the patient's ECG waveform needs defibrillation, the signal transmission module transmits the signal of the intelligent AED device and the emergency dummy to the display system through the central control platform, and the display terminal plays two pictures, one of which plays the video connection picture of the online emergency instructor, and the other plays the patient's body in a perspective state, in which the patient's heart has current passing through it in the animation, and the selected ECG waveform is displayed to show the ECG after the electric shock; S900, Cardiopulmonary Resuscitation: S910. The first aid trainee starts to perform cardiopulmonary resuscitation on the patient according to the animation reminder and voice prompt on the screen of the smart AED device and the prompt of the remote first aid instructor. The smart AED device evaluates and analyzes the quality of cardiopulmonary resuscitation in real time and gives visual and voice reminders on the screen of the smart AED device, including at least whether the compression is too fast / too slow, too deep / too shallow, and whether the compression posture is correct. S920, the recognition module captures the current first aid trainee's actions and evaluates them, the signal transmission module transmits the signals of the smart AED device and the first aid dummy to the display system through the central control platform, and the display terminal plays two pictures, one of which plays the video connection picture of the online first aid instructor, and the other plays the animation of the rescuer doing cardiopulmonary resuscitation and the specific parameters of cardiopulmonary resuscitation. In the animation, the patient's body is in a perspective state, and the patient's heart reaches different positions according to the depth of compression and blood flow, and the selected ECG waveform change animation is presented; S1000, patient awakens: S1100, repeating step S800 and step S800 until a wake-up signal is sent out on the first aid training system, the patient wakes up, and the first aid process ends; S1200. The signal transmission module transmits the awakening signal to the display system through the central control platform, and the display terminal plays the animation of the patient awakening.

[0047] In this specific step, step S700 of pasting electrodes, step S800 of defibrillation, and step S900 of cardiopulmonary resuscitation are all completed based on the interaction between the current first aid trainee and the first aid dummy, the remote guidance platform, the intelligent AED device, and the interaction between the first aid trainee, the remote guidance platform, and the display terminal. When implementing step S700 of pasting electrodes, the intelligent AED device and the remote first aid instructor's prompts allow the current first aid trainee to accurately paste the electrodes on the correct position on the patient's (first aid dummy) chest, and the relevant correct animations and corresponding data are displayed by the display terminal, so that the current first aid trainee and other trainees can simultaneously obtain feedback on the implementation of this step, thereby improving the training effect. In the process of implementing defibrillation and cardiopulmonary resuscitation, the current first aid students also interact with the first aid dummy, remote guidance platform, and intelligent AED equipment to enable the realization of this training process so that first aid students can more accurately master the operation of defibrillation and cardiopulmonary resuscitation. As the most important skills in first aid training and the skills that students need to master the most, in the various interactive relationships in this process, the operation process of defibrillation and cardiopulmonary resuscitation is demonstrated in real time on the large screen, and linked with the defibrillation and cardiopulmonary resuscitation operations of the current first aid students, helping the current first aid students to learn the first aid process more quickly and effectively, so that the current first aid students can understand whether their operations are correct in time, making the training more efficient and convenient. During the training process, experienced first aid instructors remotely and in real time guide the students' first aid operations, making the training effect better and making the first aid students' operations more scientific and standardized. At the same time, it is also displayed to the first aid students simultaneously through the display terminal, so that the students who operate and the students watching on site can master them simultaneously, further improving the training quality and training efficiency.

[0048] Due to the application of the above scheme, the present invention has the following advantages and effects compared with the prior art: 1. Through the implementation of the technical solution of the present invention, in order to solve the problems in the existing AED first aid training, such as the lack of interaction among trainees, the lack of interaction between AED implementers (trainees), patients (first aid dummies), and defibrillators, and the lack of remote guidance interaction, an innovative intelligent interactive AED first aid training system and method for teaching demonstration with more complete and effective intelligent interaction and corresponding factual feedback is designed. In the intelligent interactive AED first aid training system and method, multiple interactive relationships formed by two or more of multiple devices and personnel are used to complete the whole process of intelligent interactive AED first aid training.

[0049] 2. Through the implementation of the technical solution of the present invention, trainees can simulate real scenarios, use the emergency call function of the first aid platform, notify first aid volunteers as soon as possible, and quickly find the nearest AED device through the navigation function of the first aid platform. The animation of each first aid step is demonstrated on the large screen in real time along with the entire first aid process, which is linked to the trainees' operations to help the operating trainees learn the first aid process more quickly and effectively. Other trainees watching on site can also learn synchronously more intuitively. The recognition module on the smart AED device is used to perform real-time analysis of AED and cardiopulmonary resuscitation data, without the need for additional cameras or CPR feedback devices to collect data on the first aid process.

[0088] The interactive system includes tablet app (first aid training system), large screen TV app (display system), and first aid express app. Tablet app (configuration system): interacts with users through the interface, including server and client.

[0089] Large-screen TV app (display system): includes a server and a client, which automatically plays the corresponding first aid operation animation according to the signal of the device to provide visual feedback for trainers.

The server creates a first aid event and records the personal information and geographic location of the person seeking help. Each first aid event has a unique ID, and the QR code generated by the first aid ID is the first aid QR code.

[0092] Help call module: Users use their mobile phones to scan the QR code and enter the emergency hotline applet. The terminal application will parse the QR code to obtain the emergency ID and request the server to query the details of the emergency event corresponding to the emergency ID, including the information of the person seeking help and the geographic location.

[0093] Emergency Express Mini Program: The Emergency Express Mini Program communicates with the server via HTTP via LTE or WIFI, and sends out distress messages to nearby emergency volunteers, smart AEDs, and smart AED boxes. The smart AED box communicates with the server via HTTP and AMQP protocols via LTE or WIFI, and the AED device communicates with the server via MQTT via LTE or WIFI.
