Abstract
Description
A portable cardiopulmonary resuscitation training system and method based on multimodal feedback Technical Field
[0001] This invention relates to the field of medical emergency simulation training technology, and in particular to a portable cardiopulmonary resuscitation training system and method based on multimodal feedback. Background Technology
[0002] Currently, the most common CPR training solutions on the market are single-function training dummies, designed to provide professional CPR training tools. The core structure of this solution includes a training dummy with pressure sensors built into its chest. The execution steps are as follows: when the user performs compressions, the built-in sensors collect data on compression depth and frequency; an internal processor performs simple calculations; finally, the device uses indicator lights (such as LEDs) or a buzzer to indicate whether the compression is "too shallow," "correct," or "too deep," and whether the frequency is appropriate. However, this solution also has the following drawbacks: for example, all data is only displayed instantaneously on-site and cannot be recorded or output, lacking precise quantitative analysis and summarization, making it difficult to continuously track training effects; it is usually an isolated device, unable to aggregate, compare, and manage data from multiple devices. In group training, instructors cannot simultaneously monitor the training status of all trainees, making it difficult to efficiently organize competitions, assessments, or targeted guidance, limiting training efficiency and scale; and it is costly and complex. To achieve limited functionality, the entire system has high operating costs and complexity, making it difficult to widely adopt as a lightweight, multi-site solution in communities, schools, and other similar settings. Summary of the Invention
[0003] To address the aforementioned technical problems, this invention proposes a portable cardiopulmonary resuscitation (CPR) training system and method based on multimodal feedback. The technical solution of this invention is implemented as follows: The first aspect of this invention discloses a portable CPR training system based on multimodal feedback. The system includes a shell, a control box, and a built-in training system. The control box houses a main control MCU, a power module, a sensor module, a multimodal feedback module, and a wireless module. A pressing part is provided on the top of the shell; the pressing part has a cavity; the bottom of the shell is connected to the control box; the sensor module is located on the upper cover of the control box; the power module is located on the lower cover of the control box; the wireless module and the main control MCU are integrated on a PCB integrated board; the power module is electrically connected to the PCB integrated board; and the multimodal feedback module is located on the PCB integrated board.
[0004] The built-in training system includes a wireless management module, a data parsing and processing module, a visualization module, an evaluation module, and a data storage and report generation module. The wireless management module manages the wireless module. The data parsing and processing module processes the data stream from the wireless module. The visualization module displays the data from CPR training. The evaluation module evaluates the indicators of the user's CPR training. The data storage and report generation module stores the training data and generates training reports.
[0005] Furthermore, the power module includes a power box, a horizontal switch, a power chip, and a detachable power supply; the detachable power supply is disposed inside the power box; the horizontal switch is disposed on one side of the lower cover of the control box; and the power chip is disposed on the PCB integrated board.
[0006] Furthermore, the sensing module includes a laser displacement sensing unit; the laser displacement sensing unit is disposed on the PCB integrated board; the multimodal feedback module includes a visual feedback unit and an auditory feedback unit.
[0007] Furthermore, the wireless module includes a Bluetooth module.
[0008] The data displayed by the visualization module includes the user's pressing depth, the rebound of the pressing part, the pressing rate, the pressing interval time, the pressing depth value, and the training evaluation generated by the evaluation module.
[0009] Furthermore, the material of the pressing part is medical-grade silicone or foam.
[0010] Furthermore, it also includes a teacher's end, a mobile end, and a server; the teacher's end includes a teacher management platform; both the mobile end and the teacher's end are equipped with interfaces for communication with the wireless module; the built-in training system runs on the mobile end; the teacher management platform includes a data list module, a data details module, and an advanced analysis module; the data list module provides a data list, displaying the training data's time, sequence number, student name, student score, learning mode, and session name; the data details module provides total score and session information, and performance details; the advanced analysis module performs joint ranking of freely selected data based on training type and time, and generates a ranking list.
[0011] The second aspect of this invention discloses a portable cardiopulmonary resuscitation (CPR) training method based on multimodal feedback. The method employs the system disclosed in the first aspect of this invention and includes the following steps: Initialization and connection establishment: The power module is turned on, and the multimodal feedback module prompts the wireless module to connect; the mobile terminal connects to the wireless module through the wireless management module in the built-in training system, and the user begins CPR training according to the prompts from the multimodal feedback module; the sensing module collects user training data in real time and transmits the collected data to the data parsing and processing module via the wireless module; the data parsing and processing module parses and processes the data collected by the sensing module and transmits it to the visualization module and the evaluation module respectively; the evaluation module evaluates the user training data based on the data output by the data parsing and processing module and transmits it to the visualization module and the multimodal feedback module; the visualization module displays the user training data and training evaluation in real time, and the multimodal feedback module provides corresponding evaluation prompts based on the evaluation data from the evaluation module; after training is completed, the data storage and report generation module stores the user's training data for this session and generates a training report.
[0012] Furthermore, the data parsing and processing module processes the data as follows: The readings of the high-precision micro-laser displacement sensing unit are filtered by a moving average to obtain the instantaneous depth value; the instantaneous rate is obtained by detecting the peak point of the maximum depth reached by two consecutive presses and calculating the reciprocal of the time interval; the rebound height of the pressing part is determined; if the rebound height reaches 90% or more of the total height, it is considered sufficient rebound; otherwise, it is considered insufficient rebound; the time interval between the end of the previous press and the start of the next press is recorded by a timer.
[0013] Furthermore, the main control MCU compares the instantaneous depth value and instantaneous rate output by the data parsing and processing module with the standard threshold, compares the rebound of the pressing part with the standard state, and then controls the multi-module feedback module to give corresponding feedback prompts, and transmits the above data to the mobile terminal through the wireless module.
[0014] The advantages of this invention are as follows: 1. By integrating data from a laser sensor, this invention overcomes the limitations of traditional devices that can only monitor compression depth and frequency. The system can synchronously and accurately collect and calculate four core quality indicators: compression depth, compression rate, rebound, and compression interval time, achieving comprehensive, accurate, and real-time operational quality assessment and feedback; 2. This invention designs a multimodal feedback mechanism, including real-time feedback through the coordination of visual (LED lights) and auditory (buzzer) feedback. The LED light ring provides intuitive visual cues of the status through color changes at different positions, while the buzzer provides rhythmic auditory guidance through its rhythm. Through intuitive multimodal feedback, an immersive training experience is created, effectively promoting the rapid formation of correct muscle memory, improving training efficiency, providing intuitive and efficient multimodal sensory guidance, and accelerating muscle memory formation; 3. This invention, through Bluetooth wireless networking technology, enables a single mobile terminal to simultaneously connect to, manage, and visualize real-time data from up to 10 (or more) training devices. The instructor can view the training status of all trainees on a tablet, changing the inefficient traditional "one person, one device, instructor checks each one" model and achieving centralized, standardized teaching management for one-to-many training. This improves the efficiency and coverage of group training, reduces instructor costs, and makes it possible to implement high-quality CPR teaching in large-scale training (such as in schools, communities, and enterprises), building a highly efficient and scalable group training management model. Furthermore, this invention uses a mobile terminal application to completely record timestamp data from all hardware, which can be stored in a local database and uploaded to the cloud. After training, a personal training report with detailed statistical charts can be generated, solving the problem of traditional training being "undocumented" and achieving digital archiving and traceability of the training process. Coaches and trainees can conduct precise post-class analysis and targeted improvements based on objective data, providing indisputable quantitative evidence for teaching assessment, promoting the refinement and scientification of training management, and realizing traceability of the training process and quantitative analysis of training effects; 5. This invention highly integrates sensing, computing, feedback, and communication modules into a lightweight, all-in-one hardware, eliminating the need for complex external devices and enabling powerful functions through common tablet computers and Bluetooth technology. Beneficial effects: The entire system is compact, lightweight, portable, and easy to deploy, allowing for rapid training in any location. Simultaneously, utilizing a common mobile terminal as the display and computing core avoids dedicated, high-cost hardware, reducing the overall manufacturing cost and usage threshold of the system, facilitating the rapid promotion and popularization of the technology at the social level, and achieving excellent portability, integration, and cost-effectiveness.
[0015] 6. This invention supports both group and individual training. Teachers can simultaneously view the training data of multiple students on their own devices, and students can also use a mini-program on their mobile devices for self-training, both of which provide visualized data feedback.
