Description

Technical Field

[0001] This utility model relates to the field of medical emergency training technology, and in particular to a cardiopulmonary resuscitation training device with feedback function. Background Technology

[0002] A common problem with existing CPR training devices is that they often focus only on training chest compressions and artificial respiration, neglecting other equally important steps in CPR, such as assessing the environment, calling emergency services (120 in China), checking heart rate and breathing (including checking the carotid artery to determine if the heart has stopped), and opening the airway. These steps are equally indispensable in actual CPR operations, and their correct execution is crucial to ensuring effective resuscitation.

[0003] Due to the limitations of existing training devices, trainees may not fully understand and master the complete CPR procedure during training, leading to the omission of important steps in actual emergency situations, thus affecting the rescue effect and patient survival rate. Furthermore, existing training devices rely on manual operation to record trainee progress, which is not only time-consuming and labor-intensive but also prone to errors and cannot accurately reflect the trainees' training results. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a cardiopulmonary resuscitation training device with feedback function, which can make the training more closely resemble actual emergency rescue scenarios and prevent trainees from missing important steps.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0006] A cardiopulmonary resuscitation training device with feedback function includes:

[0007] The main torso, simulated neck, and simulated human head;

[0008] The human body control panel is located on the bottom side inside the main body of the torso;

[0009] The voice recognition module is installed inside the training device. When the trainee utters a sentence containing "environmental safety" or "call 120", the voice recognition module recognizes and responds. If the trainee does not shout or the information is incomplete, the voice recognition module fails to recognize the sentence, and the human body control board issues the corresponding instructions to "assess the environment" and "call 120" respectively.

[0010] A push-button switch is located on the simulated neck to determine whether the trainee has touched the carotid artery;

[0011] Indicator light 1 is located on the neck. When the trainee completes the action of touching the carotid artery, the indicator light will light up or the simulated human internal circuit module will emit sound or vibration to indicate that the current operation is completed.

[0012] An angle sensor, installed on the simulated neck, is used to detect the head tilt angle. If the angle is insufficient or excessive, the human body main control board issues a prompt. After the trainee completes the airway opening action, the second indicator light illuminates or the internal circuit module of the simulated human emits a sound or vibration prompt to indicate that the current operation is completed.

[0013] A speaker, located inside the main body of the torso, is used to emit a prompt sound in conjunction with the indicator light when the trainee completes a training step, instructing the trainee to proceed to the next step.

[0014] A touch-sensitive switch is located in the center of the chest of the training device, at the midpoint of the line connecting the two nipples, to provide feedback on whether the trainee's pressing position is accurate.

[0015] Furthermore, the push-button switch can also be a touch-sensitive switch, a tactile switch, a membrane switch, a rocker switch, or a micro switch.

[0016] Furthermore, the button switch is triggered after the student completes the action of touching the carotid artery, and the indicator light on the neck lights up or the simulated human internal circuit module emits sound or vibration to indicate that the current operation has been completed.

[0017] Furthermore, the angle sensor can also be a micro switch. When the simulated human head tilts back, the micro switch opens, indicating that the airway is open. The human body main control board issues a command prompt. When the trainee completes the airway opening action, the second indicator light illuminates or the simulated human internal circuit module emits a sound or vibration prompt to indicate that the current operation is completed.

[0018] Furthermore, the cardiopulmonary resuscitation training device is connected to external devices, including mobile phones, tablets, computers, and controller boxes, via wired or wireless means, and feeds back training data to the external devices. The external devices automatically record whether the trainee has completed the operations of assessing the environment, calling 120, touching the carotid artery, and opening the airway.

[0019] Furthermore, a touch-sensitive switch is installed at the midpoint of the line connecting the two nipples in the center of the chest of the training device. This switch provides feedback on whether the student's pressing position is accurate. When the student presses the correct position, indicator light three illuminates, or the internal circuit module of the simulator emits a sound or vibration to indicate that the operation is complete. The touch-sensitive switch can also be a button switch, a tactile switch, a membrane switch, or a micro switch.

[0020] The above-described solution of this utility model has at least the following beneficial effects:

[0021] By adding feedback functionality, this device can provide real-time prompts to trainees on whether they have completed key operational steps during training, such as assessing the environment, calling 120 (emergency services), checking the carotid artery, and opening the airway. This instant feedback mechanism helps trainees promptly identify and correct their mistakes, thereby mastering CPR skills more accurately and improving training effectiveness.

[0022] During training simulating real-life emergency scenarios, trainees need to quickly and accurately complete a series of operations. This device, by simulating these operations and providing feedback, effectively cultivates trainees' rapid response and decision-making abilities in emergency situations, enabling them to handle future real-life emergency scenarios more calmly. The device's design makes CPR training more intuitive and easy to understand, suitable not only for professional medical personnel but also for the general public to learn and practice. By promoting and using this device, more people can understand and master CPR skills, thereby improving the public's self-rescue and mutual-rescue capabilities and reducing mortality rates caused by cardiac arrest and other reasons.

[0023] Traditional CPR training devices typically rely on manual operation to record trainees' progress, which is time-consuming, labor-intensive, and prone to errors. This device automatically records whether trainees have completed key operational steps and presents the results in a statistical report, significantly saving manual recording time, reducing the possibility of errors, and improving the accuracy and reliability of training data. This device supports wired or wireless connection and data transmission with external devices (such as mobile phones, tablets, computers, and controller boxes), making training scenarios more flexible and diverse. CPR training can be conveniently conducted in medical institutions, schools, communities, and homes, meeting the learning needs of different groups. Attached Figure Description

Main body of torso; 8. Simulated neck; 9. Simulated human head; 10. Indicator light 2; 11. Indicator light 3; 12. Touch sensor switch. Detailed Implementation

[0026] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0027] like Figure 1 As shown, an embodiment of this utility model proposes a cardiopulmonary resuscitation training device with feedback function, comprising:

[0028] 7. Main torso, 8. Simulated neck, and 9. Simulated human head;

[0029] The human body control board 1 is located on the bottom side inside the main body 7 of the torso.

[0030] The voice recognition module 2 is located inside the training device. When the trainee utters a sentence containing "environmental safety" or "call 120", the voice recognition module 2 recognizes and responds. If the trainee does not shout or the information is incomplete, the voice recognition module 2 fails to recognize the sentence, and the human body control board 1 issues the corresponding instructions to "assess the environment" and "call 120".

[0031] A button switch 3 is located on the simulated neck 8 and is used to determine whether the trainee has touched the carotid artery.

[0032] Indicator light 5 is located on the neck 8. When the student completes the action of touching the carotid artery, indicator light 5 will light up or the simulated human internal circuit module will emit sound or vibration to indicate that the current operation is completed.

[0033] Angle sensor 4 is installed on the simulated neck 8 to detect the head tilt angle. If the angle is insufficient or excessive, the human body main control board will issue a prompt. After the trainee completes the airway opening action, indicator light 10 will light up or the internal circuit module of the simulated human will emit a sound or vibration prompt to indicate that the current operation is completed.

[0034] The speaker 6 is located inside the main body 7 and is used to emit a prompt sound in conjunction with the indicator light when the trainee completes a training step, instructing the trainee to proceed to the next step.

[0035] In this embodiment of the invention, when a trainee begins CPR training, if the trainee loudly utters phrases containing "safe environment" or "call 120," the voice recognition module 2 will immediately recognize these phrases. If the voice recognition module 2 successfully recognizes the trainee's voice command, the training will continue; if recognition fails (e.g., the trainee did not shout or the information is incomplete), the human body control board 1 will immediately issue corresponding prompts, such as "Please assess the environment" or "Please call 120," to guide the trainee through these crucial steps.

[0036] During training, trainees need to touch the carotid artery on the simulated neck (8) to simulate assessing whether a patient's heart has stopped beating. Upon touching the carotid artery, the trainee triggers button switch 3. This action is detected by the main control board 1, which then controls indicator light 5 on the neck (8) to illuminate, or emits a sound or vibration through the simulated mannequin's internal circuitry to indicate completion. The trainee then tilts the simulated mannequin's head (9) back to open the airway. When the head is tilted back to a certain angle (e.g., 30°), angle sensor 4 on the simulated neck (8) is activated. The main control board 1 detects the activation of angle sensor 4. If the angle is appropriate, training continues; if the angle is insufficient or excessive, the main control board 1 issues a command to the trainee to adjust the head position to ensure an open airway. Throughout the training, speaker 6 works in conjunction with indicator light 10. Whenever the trainee completes a key step, speaker 6 emits a prompt sound, and indicator light 10 illuminates or flashes to indicate the next step.

[0037] Through a real-time feedback mechanism, trainees can promptly understand their performance during training, correct mistakes in a timely manner, and thus master CPR skills more accurately. The training process, simulating real-life emergency scenarios, cultivates trainees' rapid response and decision-making abilities in emergency situations, enabling them to handle future real-world emergency situations with greater composure. Intuitive and easy-to-understand operation prompts and feedback mechanisms make the training process smoother and more efficient, enhancing the trainee's training experience. This device is not only suitable for professional medical personnel but also for the general public to learn and practice, helping to promote the popularization of first aid knowledge and improve the public's self-rescue and mutual-rescue capabilities. The automated feedback and recording mechanism saves time compared to manual recording, reduces the possibility of errors, and improves the accuracy and reliability of training data.

[0038] like Figure 1 As shown, the push-button switch 3 can also be a touch-sensitive switch, a tactile switch, a membrane switch, a rocker switch, or a micro switch.

[0039] In this embodiment of the invention, the push-button switch 3 is used to detect whether the trainee has touched the carotid artery on the simulated neck 8, in order to simulate the operation of determining whether a patient's heart has stopped beating. The push-button switch 3 is designed to be of various interchangeable types, including touch-sensitive switches, tactile switches, membrane switches, rocker switches, or micro switches. These different types of switches have different triggering mechanisms and sensitivities, but all can effectively detect the trainee's touch actions.

[0040] Regardless of the type of button switch 3 used, once the trainee completes the action of touching the carotid artery, the switch is triggered. The human body control board 1 receives this signal and controls the indicator light 5 set on the simulated neck 8 to light up, or emits a sound or vibration prompt through the internal circuit module of the simulated human to indicate that the current operation has been completed. At the same time, the speaker 6 will also emit a prompt sound in conjunction with the indicator light 5 to instruct the trainee to perform the next operation.

[0041] The device offers a variety of button switches3, allowing for flexible configuration based on different usage scenarios and trainee needs. For example, touch-sensitive switches or microswitches can be selected for applications requiring high sensitivity, while rocker switches can be chosen for situations where a clear on / off status is needed. Different types of button switches offer different triggering mechanisms and tactile feedback, allowing trainees to choose the switch type according to their preferences, thereby improving user experience and training effectiveness. Using high-quality button switches, such as microswitches, reduces wear and tear and malfunctions caused by frequent use, extending the lifespan of the training device. Different types of button switches can meet the needs of trainees of different ages, genders, and hand conditions, making CPR training devices more widespread and applicable.

[0042] like Figure 1 As shown, the button switch 3 is triggered after the student completes the action of touching the carotid artery, and the indicator light 5 on the simulated neck 8 lights up or the internal circuit module of the simulated person emits sound or vibration to indicate that the current operation has been completed.

[0043] In this embodiment of the invention, the push-button switch 3 is designed on the simulated neck 8 to simulate the operation of detecting whether the trainee has touched the carotid artery to determine whether the patient's heart has stopped beating. When the trainee correctly touches the carotid artery on the simulated neck according to the training procedure, the push-button switch 3 is triggered, and this triggering action is immediately sensed by the human body control board 1 connected to the push-button switch.

[0044] Once the human body control board 1 receives the signal from the trigger of the button switch 3, it will immediately execute a series of preset operations. First, it will control the indicator light 5 set on the simulated neck 8 to light up, this visual signal intuitively informing the trainee that the current operation (touching the carotid artery) has been completed. At the same time, in order to further enhance the feedback effect, the human body control board 1 may also control the circuit module inside the simulated human to emit specific sound prompts, such as a short beep or a voice prompt "carotid artery touch completed", to confirm the completion of the operation again in an auditory form. Through this multi-sensory feedback mechanism, the trainee can immediately know whether his operation is correct, so as to carry out the next step of training or adjustment in a timely manner.

[0045] The triggering of button switch 3 and the illumination of indicator light 5 (or the emission of sound) create an instant feedback mechanism, allowing trainees to immediately confirm whether they have correctly performed the carotid artery palpation procedure. This instant feedback helps trainees identify and correct errors in a timely manner during training, improving training efficiency. Through dual feedback—visual (indicator light) and auditory (sound prompts)—the trainee's training experience is enhanced. This multi-sensory feedback method makes the training process more vivid and interesting, helping to stimulate trainees' learning interest and enthusiasm. A clear feedback mechanism helps trainees accurately grasp each step and key point of CPR. In the crucial step of palpating the carotid artery, the triggering of the button switch and the feedback from the indicator light / sound allow trainees to more clearly understand and remember the correct procedure. Long-term practice with this training device featuring instant feedback enables trainees to master CPR skills more quickly and perform the procedure more confidently and accurately in actual emergency situations.

[0046] like Figure 1 As shown, the angle sensor 4 can also be a micro switch. When the simulated human head tilts back, the micro switch opens, indicating that the airway is open. The human body main control board issues a command prompt. When the trainee completes the airway opening action, the indicator light 10 lights up or the simulated human internal circuit module emits a sound or vibration prompt to indicate that the current operation is completed.

[0047] In this embodiment of the invention, the angle sensor 4 precisely detects the tilting angle of the simulated human head 9 to confirm whether the airway has been correctly opened. This design simulates a key step in opening the airway during cardiopulmonary resuscitation (CPR), namely, ensuring an open airway by tilting the patient's head back at a certain angle (e.g., 30°). When trainees perform the airway opening operation during training, they need to tilt the simulated human head 9 back. At this time, the angle sensor 4 starts working, monitoring the tilting angle of the head in real time. If the angle reaches the preset value (30°), it indicates that the airway has been correctly opened, and the human body control board 1 will receive a success signal from the angle sensor 4.

[0048] Once the airway is confirmed to be open, the main control board 1 will immediately control the indicator light 10 on the simulated neck 8 to illuminate, or emit a sound or vibration prompt through the internal circuit module of the simulated human, such as a short beep or a voice prompt "Airway opened successfully." This visual or auditory signal informs the trainee that the current operation is complete and guides them to the next training step. If the angle sensor 4 detects that the head tilt angle is insufficient or excessive, the main control board 1 will immediately issue a prompt, such as a voice prompt "Please adjust your head position to ensure the airway is open." This feedback mechanism helps the trainee correct errors in a timely manner and ensures that the airway is opened correctly.

[0049] The precise detection of the head tilt angle by angle sensor 4 ensures that trainees correctly perform the airway opening procedure during training. This precision helps improve trainees' skill level, enabling them to perform CPR more accurately in real-life emergency scenarios. The illumination or sound of indicator light 10 provides trainees with immediate visual and auditory feedback, allowing them to immediately confirm whether they have correctly performed the airway opening procedure. This multi-sensory feedback mechanism helps deepen trainees' memory and understanding of the steps. Precise angle detection and immediate feedback make the training process more intuitive and easier to understand, enhancing the trainees' training experience. This positive learning experience helps stimulate trainees' interest and increases their enthusiasm and initiative in training. Through repeated practice and immediate feedback, trainees can master CPR skills more quickly, including key steps such as correctly assessing the environment, calling 120 (emergency services), checking the carotid artery, and opening the airway. Mastering these skills is crucial for improving the success rate of emergency care.

[0050] like Figure 1 As shown, the cardiopulmonary resuscitation training device is connected to external devices, including mobile phones, tablets, computers, and controller boxes, via wired or wireless means, and feeds back training data to the external devices. The external devices automatically record whether the trainee has completed the operation of assessing the environment, calling 120, touching the carotid artery, and opening the airway.

[0051] In this embodiment of the invention, during training, when the trainee completes each key operation, such as assessing the environment, calling 120 (emergency services), touching the carotid artery, and opening the airway, the sensors and circuit modules inside the CPR training device detect and record data of these operations in real time. This data includes the timestamp of the operation, whether the operation was successful or not, and any relevant sensor readings (such as the pressure when touching the carotid artery, the angle of head tilt, etc.). Once this data is collected, the CPR training device packages and sends it to a connected external device via a preset data transmission protocol. After receiving the data, the external device automatically parses and processes it, presenting the trainee's operation record in an intuitive form, such as the operation sequence, operation time, and operation result.

[0052] For operations requiring voice recognition, such as assessing the environment and calling 120 (emergency services), the CPR training device internally performs the recognition and sends the result as part of the data to an external device. This allows the external device to comprehensively and accurately record the trainee's performance throughout the training process.

[0053] By automatically recording trainees' operational data through external devices, the training process can be digitally managed. This helps training institutions or coaches to comprehensively and objectively evaluate trainees' progress, providing strong data support for subsequent training and improvement. External devices can display trainees' operational results in real time, allowing them to immediately understand their training status. For unsuccessful operations, trainees can receive timely feedback and make targeted improvements, thereby increasing training efficiency.

[0054] Through wireless connectivity, instructors or medical institutions can remotely monitor trainees' progress, providing real-time guidance and suggestions. The collected training data can be analyzed and researched to help medical and training institutions understand the learning curve, challenges, and common mistakes in CPR skills, thereby optimizing training content and methods. Connectivity with external devices makes the training process more intelligent and interactive, enhancing the trainee's experience. Trainees can view their training records through external devices, understanding their progress and shortcomings, thus encouraging more active participation in training.

[0055] like Figure 1 As shown, a touch-sensitive switch 12 is installed at the midpoint of the line connecting the two nipples in the center of the chest of the cardiopulmonary resuscitation training device. When the trainee's palm is placed in the correct compression position, the indicator light 11 on the chest lights up and the internal circuit module of the mannequin emits a sound or vibration to indicate that the current compression position is correct. The touch-sensitive switch 12 can also be a button switch, a tactile switch, a membrane switch, or a micro switch.

[0056] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
