Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a control method, device, equipment and medium for a defibrillator. Background Technology

[0002] Cardiac arrest (CA) is one of the major public health challenges worldwide. The core of high-quality cardiopulmonary resuscitation (CPR) lies in continuously providing guideline-compliant chest compressions and promptly delivering defibrillable rhythms (such as ventricular fibrillation) with defibrillation.

[0003] However, existing defibrillator devices still have certain limitations in their control logic design. Their optimization focuses primarily on a single, independent step in the CPR sequence, such as simply increasing the frequency or depth of chest compressions, or focusing solely on the timing of defibrillation. In practical applications, this approach lacks a systematic integration and coordinated control strategy for the entire CPR process. It cannot dynamically adjust parameters at each stage based on the patient's real-time physiological state, thus severely impacting the quality of continuous blood perfusion during CPR. Therefore, achieving precise and coordinated control of the entire CPR process is a pressing technical problem that needs to be solved. Summary of the Invention

[0004] Therefore, in response to the above-mentioned technical problems, this invention provides a control method, device, equipment, and medium for a defibrillator, which can achieve precise and coordinated control of the entire cardiopulmonary resuscitation process.

[0005] A first aspect of this application provides a control method for a defibrillator, the control method comprising: Based on the preset cardiopulmonary resuscitation cycle pattern, the ventilation phase in the next cardiopulmonary resuscitation cycle is determined as the ventilation control window. Based on the window control command triggered by the ventilation control window, the time-limited heart rhythm task and capacitor charging task are executed. Based on the monitored first completion status of the time-limited heart rhythm task and the second completion status of the capacitor charging task, determine whether the preset discharge conditions are met. If the preset discharge conditions are met, the defibrillator will be controlled to deliver an electric shock within the preset discharge time.

[0006] A second aspect of this application provides a control device for a defibrillator, the control device comprising: The determination module is used to determine the ventilation phase in the next cardiopulmonary resuscitation cycle as the ventilation control window based on the preset cardiopulmonary resuscitation cycle pattern. The triggering module is used to execute time-limited heart rhythm tasks and capacitor charging tasks based on window control commands triggered by the ventilation control window. The judgment module is used to determine whether the preset discharge conditions are met based on the first completion status of the time-limited heart rhythm task and the second completion status of the capacitor charging task monitored. The control module is used to control the defibrillator to deliver an electric shock within a preset discharge time if preset discharge conditions are met.

[0007] Thirdly, a defibrillation device is provided, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor, when executing the computer program, implements the control method of the defibrillation device as described in the first aspect.

[0008] Fourthly, a computer-readable storage medium is provided, the computer-readable storage medium storing a computer program that, when executed by a processor, implements the control method of the defibrillator as described in the first aspect.

[0009] In summary, this invention provides a control method, apparatus, device, and medium for a defibrillator. Based on a preset cardiopulmonary resuscitation (CPR) cycle mode, the ventilation phase in the next CPR cycle is determined as the ventilation control window. Based on the window control command triggered by the ventilation control window, a time-limited heart rhythm task and a capacitor charging task are executed. According to the monitored first completion status of the time-limited heart rhythm task and the second completion status of the capacitor charging task, it is determined whether a preset discharge condition is met. If the preset discharge condition is met, the defibrillator is controlled to deliver an electric shock within a preset discharge time. Therefore, this application determines whether the preset discharge condition is met based on the monitored first completion status of the time-limited heart rhythm task and the second completion status of the capacitor charging task, and then controls the defibrillator to deliver an electric shock within a preset discharge time, thereby achieving precise and coordinated control of the entire CPR process, thus reducing the compression interruption time to an extremely low level.

[0019] To illustrate the technical solution of the present invention, specific embodiments are described below.

[0020] See Figure 1 This is a flowchart illustrating a control method for a defibrillator according to an embodiment of the present invention, as shown below. Figure 1 As shown, the control method of this defibrillator can be achieved through the following steps.

[0021] S101: Based on the preset cardiopulmonary resuscitation cycle mode, determine the ventilation stage in the next cardiopulmonary resuscitation cycle as the ventilation control window.

[0022] In one implementation, based on a pre-set cardiopulmonary resuscitation (CPR) cycle mode, the ventilation phase of the next CPR cycle is clearly defined as a ventilation control window by analyzing the current cycle status. This CPR cycle mode refers to a pattern where CPR is performed according to a preset compression-to-ventilation ratio and duration. In practice, the ventilation control window can be directly set for defibrillation using a defibrillator. The start time and duration of the ventilation control window are dynamically adjusted based on the patient's condition and preset parameters to ensure coordination between ventilation and other aspects of CPR (such as chest compressions) for optimal results. This dynamic adjustment mechanism not only improves the flexibility and adaptability of CPR but also reduces the risk of complications caused by improper operation. For example, after a certain number of CPR cycles, the arrival of the next ventilation phase can be observed and marked as a ventilation control window.

[0023] In this embodiment, by determining the ventilation control window, accurate ventilation can be performed on the patient at the appropriate time, thereby improving the success rate of cardiopulmonary resuscitation. Simultaneously, the defibrillator can monitor the patient's physiological parameters in real time, such as heart rate and blood oxygen saturation, providing more precise data support for dynamically adjusting the ventilation control window. When a significant change in the patient's physiological parameters is detected, the device can react quickly and adjust the relevant parameters of the ventilation control window to adapt to the patient's current physiological state. Furthermore, the device has an intelligent alarm function; when the adjustment of the ventilation control window exceeds the preset safety range, the device will immediately issue an alarm to remind medical personnel to intervene promptly, thereby ensuring the patient's safety.

[0024] S102: Execute time-limited heart rhythm tasks and capacitor charging tasks based on the window control command triggered by the ventilation control window.

[0025] In one implementation, at the start of the ventilation control window—the instant ventilation begins after the last compression—a unified hardware trigger signal generates a window control command. This command ensures the defibrillator simultaneously executes time-limited rhythm and capacitor charging tasks, guaranteeing accurate response and completion of each task according to preset timing and conditions. Specifically, during the time-limited rhythm task, the system precisely controls the detection time and frequency of the heart rhythm based on preset algorithms and parameters, acquiring and analyzing the patient's heart rhythm data in real time to determine if the patient's current heart rhythm is normal. If an abnormal heart rhythm is detected, the system records the relevant information promptly, providing data for subsequent operations. During the capacitor charging task, the system precisely charges the capacitor according to set charging parameters, ensuring it reaches the appropriate energy state for defibrillation. Simultaneously, the system monitors the charging process in real time to prevent overcharging and other abnormalities, ensuring the safe and stable operation of the device. By simultaneously executing time-limited heart rhythm tasks and capacitor charging tasks in parallel under the ventilation control window, real-time monitoring and judgment of the patient's heart rhythm during cardiopulmonary resuscitation and precise charging control of the defibrillator capacitor are achieved, thereby improving the overall safety and effectiveness of the operation.

[0026] S103: Based on the monitored first completion status of the time-limited heart rhythm task and the second completion status of the capacitor charging task, determine whether the preset discharge conditions are met.

[0027] In one implementation, the defibrillator monitors the first completion status of a time-limited heart rhythm task and the second completion status of a capacitor charging task in real time. Based on these monitoring results, the defibrillator automatically executes a comprehensive judgment program to assess whether preset discharge conditions are met. Specifically, the defibrillator first checks if the first completion status of the time-limited heart rhythm task meets preset standards, and then verifies if the second completion status of the capacitor charging task meets the requirements. Only when both tasks simultaneously meet the preset conditions will the system determine that the discharge conditions are met, thus initiating the discharge operation. Throughout this process, the defibrillator strictly adheres to preset algorithms and logical rules to ensure the accuracy and reliability of the judgment. For example, regarding the first completion status of the time-limited heart rhythm task, the device compares it with preset standards such as heart rhythm monitoring time and data analysis results to confirm whether an accurate assessment of the heart rhythm status has been completed. For the second completion status of the capacitor charging task, the device checks the capacitor's charging time and whether charging is complete to ensure that the capacitor has reached a suitable energy state and is safe and stable. Only when both of these conditions are met will the defibrillator decisively initiate the discharge operation to provide timely and effective defibrillation for the patient.

[0028] In this embodiment, by monitoring the first completion state of the time-limited heart rhythm task and the second completion state of the capacitor charging task, the defibrillator can accurately control the timing of the discharge operation, effectively avoiding invalid discharge or untimely discharge due to misjudgment, greatly improving the success rate and safety of cardiopulmonary resuscitation defibrillation operation, and providing stronger protection for the patient's life safety.

[0029] S104: If the preset discharge conditions are met, the defibrillator will be controlled to deliver an electric shock within the preset discharge time.

[0030] S105: If the preset discharge conditions are not met, control the defibrillator to terminate the current discharge and execute the next cardiopulmonary resuscitation cycle.

[0031] In one implementation, if preset discharge conditions are met, the defibrillator control process is initiated, and the defibrillator operation is completed within the preset discharge time range. After the defibrillator operation, the defibrillator automatically and seamlessly resumes chest compressions without any delay to ensure the efficiency and continuity of the emergency response process. If the preset discharge conditions are not met, it means that after monitoring and judging the first completion status of the time-limited heart rhythm task and the second completion status of the capacitor charging task, the current situation is found to be inconsistent with the prerequisites for performing the defibrillator operation. For example, the patient's heart rhythm may not be a defibrillable rhythm, or the defibrillator capacitor may not have reached the charging completion state. This situation of not meeting the conditions can be detected in various ways. For example, the system can continuously monitor the heart rhythm analysis results. If the heart rhythm analysis results show a non-defibrillable rhythm (such as a rhythm other than ventricular fibrillation or pulseless ventricular tachycardia), it is determined that the conditions are not met. Another example is that the system can monitor the charging status of the capacitor. If the target charging energy is not reached within the preset time, it is determined that the conditions are not met, and the current discharge is terminated, and the energy is safely released to seamlessly transition to the next cardiopulmonary resuscitation cycle. This process closely integrates defibrillation decision-making with the cardiopulmonary resuscitation cycle. Even if defibrillation conditions are not met, it will not lead to defibrillation interruption or the equipment being in an unsafe state. Instead, it can continue subsequent life support efficiently and safely, thereby improving the safety and efficiency of the entire cardiopulmonary resuscitation defibrillation process.

[0032] In summary, this invention provides a control method, apparatus, device, and medium for a defibrillator. Based on a preset cardiopulmonary resuscitation (CPR) cycle mode, the ventilation phase in the next CPR cycle is determined as the ventilation control window. Based on the window control command triggered by the ventilation control window, a time-limited heart rhythm task and a capacitor charging task are executed. According to the monitored first completion status of the time-limited heart rhythm task and the second completion status of the capacitor charging task, it is determined whether a preset discharge condition is met. If the preset discharge condition is met, the defibrillator is controlled to deliver an electric shock within a preset discharge time. Therefore, this application determines whether the preset discharge condition is met based on the monitored first completion status of the time-limited heart rhythm task and the second completion status of the capacitor charging task, and then controls the defibrillator to deliver an electric shock within a preset discharge time, thereby achieving precise and coordinated control of the entire CPR process, thus reducing the compression interruption time to an extremely low level.

[0033] In one embodiment, specifically in step S101, which involves determining the ventilation phase of the next cardiopulmonary resuscitation cycle as the ventilation control window based on a preset cardiopulmonary resuscitation cycle pattern, the following steps are included: Get the current count of cardiopulmonary resuscitation cycles; Determine whether the count has reached a preset loop count threshold; If the number of counts reaches the preset cycle count threshold, then the ventilation phase in the next cardiopulmonary resuscitation cycle is determined as the ventilation control window.

[0034] In one implementation, a defibrillator continuously monitors and records the count of completed cardiopulmonary resuscitation (CPR) cycles. This can be achieved by incrementing the counter upon detecting the completion of each ventilation or compression sequence, or by automatically identifying and recording the cycle completion method using an integrated timer and motion sensor. Specifically, the defibrillator performs a preset number of standard 30:2 compression-ventilation cycles (e.g., four) and counts the number of cycles to determine if the current CPR cycle count has reached a preset cycle count threshold. This threshold can be set based on clinical guidelines, patient condition, or device configuration; for example, it could be set to four cycles to ensure the patient has received sufficient basic CPR before defibrillation preparation. If the count reaches the preset cycle count threshold, the ventilation phase of the next CPR cycle is designated as the ventilation control window. This means that once the preset cycle count requirement is met, the system strategically selects the immediately following ventilation phase as the specific time window for performing time-limited rhythm and capacitor charging tasks.

[0035] For example, in a CPR session, a preset threshold of 5 cycles is set. The CPR device continuously monitors and records the number of completed CPR cycles. When the device detects that the 5th CPR cycle has been completed, it determines that the current count of 5 has reached the preset threshold of 5 cycles. At this point, the device strategically designates the ventilation phase of the upcoming 6th CPR cycle as the ventilation control window. Within this designated ventilation control window, the system triggers window control commands, thereby executing time-limited heart rhythm tasks and capacitor charging tasks to prepare for subsequent defibrillation control. This technical solution makes the timing of critical task initiation more precise and reasonable, avoiding premature initiation of defibrillation preparation tasks in the early stages of CPR and improving the success rate of CPR.

[0036] In one embodiment, specifically in step S103, which involves determining whether the preset discharge conditions are met based on the monitored first completion status of the time-limited heart rhythm task and the second completion status of the capacitor charging task, the following steps are included: Determine whether the first completion state of the time-limited heart rhythm task is a defibrillable heart rhythm state, and determine whether the second completion state of the capacitor charging task is a charging completion state. If the first completion state of the time-limited heart rhythm task is a defibrillable heart rhythm state, and the second completion state of the capacitor charging task is a charging completion state, then the preset discharge condition is determined to be met.

[0037] In one implementation, the defibrillator determines whether the first completion state of the time-limited rhythm task is a defibrillable rhythm state and whether the second completion state of the capacitor charging task is a charging completion state. If both conditions are met—that is, the first completion state of the time-limited rhythm task is a defibrillable rhythm state and the second completion state of the capacitor charging task is a charging completion state—then the defibrillator will further confirm that the preset discharge conditions have been met. Upon confirmation that the preset discharge conditions are met, the defibrillator will immediately initiate the discharge procedure, releasing precisely controlled electric shock energy to the patient to perform an effective defibrillation operation. Simultaneously, the device will continuously monitor the patient's electrocardiogram signals and physiological parameters to ensure the safety and effectiveness of the defibrillation process. If defibrillation is successful, the device will automatically adjust to the subsequent cardiopulmonary resuscitation support mode; if defibrillation is unsuccessful, the device will decide whether to perform a second defibrillation or adjust the defibrillation energy according to preset algorithms and strategies to maximize the patient's chances of survival. Through these steps, this dual-confirmation mechanism greatly improves the accuracy and reliability of defibrillation decisions, enabling dynamic adjustments to the operational strategy based on the patient's real-time condition to ensure the most appropriate operation is performed at the optimal time. This process not only demonstrates a high degree of automation and intelligence, but also greatly improves the success rate of cardiopulmonary resuscitation and defibrillation, providing a more solid guarantee for the safety of patients' lives.

[0038] In one embodiment, determining whether the first completion state of the time-limited rhythm task is a defibrillable rhythm state includes the following steps: Obtain the first maximum execution duration of the time-limited heart rhythm task; Determine whether the first maximum execution duration of the time-limited heart rhythm task is not greater than the target ventilation duration of the ventilation control window; If the first maximum execution duration of the time-limited rhythm task is not greater than the target ventilation duration of the ventilation control window, then the first completion state of the time-limited rhythm task is determined to be a defibrillable rhythm state.

[0039] In one implementation, the patient's heart rhythm is analyzed to obtain a first maximum execution time for the time-limited rhythm task. This first maximum execution time is an upper limit set by the defibrillator to ensure that the rhythm analysis process is completed within a specified time. For example, the rhythm analysis algorithm can be performance-tested and evaluated during the defibrillator design phase to determine its worst-case execution time, which can then be used as the first maximum execution time. Alternatively, the defibrillator can dynamically monitor the actual execution time of the rhythm task and, in conjunction with historical data or preset thresholds, adjust or determine a reasonable maximum execution time in real time. This allows the system to determine whether the first maximum execution time of the time-limited rhythm task does not exceed the target ventilation time within the ventilation control window. This primarily ensures that the analysis of the time-limited rhythm task can be completed within the ventilation control window, thereby avoiding conflicts between the rhythm analysis process and ventilation operations and ensuring the smooth progress of the cardiopulmonary resuscitation (CPR) procedure. For example, a timer can be set to start at the beginning of the ventilation control window and monitor the progress of the rhythm task. If the rhythm task is completed before the timer reaches the first maximum execution time, the condition is met. If the first maximum execution duration of the time-limited rhythm task is not greater than the target ventilation duration of the ventilation control window, then the first completion state of the time-limited rhythm task is determined to be a defibrillable rhythm state. This is the final determination of the completion status of the rhythm task, indicating that the system has successfully identified the patient's rhythm as defibrillable, and that this identification process was completed within the specified time, providing a basis for subsequent discharge operations. For example, when the rhythm analysis algorithm outputs a defibrillable rhythm (such as ventricular fibrillation or pulseless ventricular tachycardia) and the above duration judgment is true, the system's internal status register or flag is set to the defibrillable rhythm state. Alternatively, a specific signal or message can be sent to the main controller to indicate that the rhythm task has been completed within the specified time and that the rhythm type is defibrillable. Upon receiving this signal, the main controller updates the first completion state to the defibrillable rhythm state.

[0040] In this embodiment, to ensure the timeliness and safety of defibrillation, especially during the ventilation phase for rhythm determination, strict control over the execution duration of the time-limited rhythm task is introduced. First, the system obtains the first maximum execution time for rhythm determination, representing the longest possible time required for the rhythm analysis task. Then, this first maximum execution time is compared with the target ventilation duration of the current ventilation control window. If the longest execution time of the rhythm analysis task does not exceed the available time during ventilation, the rhythm task can be considered to be completed without interfering with ventilation. Once this condition is met, and the rhythm analysis result indeed indicates a defibrillable rhythm, the system determines the first completion state of the time-limited rhythm task as a defibrillable rhythm state. This mechanism is closely integrated with the steps of determining whether preset discharge conditions are met and whether the first completion state of the time-limited rhythm task is a defibrillable rhythm state. By incorporating additional consideration of execution time when determining defibrillable rhythm status, the effectiveness and timeliness of rhythm assessment are ensured, avoiding delays in defibrillation or conflicts with ventilation operations due to excessively long rhythm analysis time. This makes the entire defibrillation control process more efficient and safer, thereby improving the patient's resuscitation success rate.

[0041] In one embodiment, determining whether the second completion state of the capacitor charging task is a charging completion state includes the following steps: Obtain the second maximum execution time of the capacitor charging task; Determine whether the second maximum execution time of the capacitor charging task is not greater than the target ventilation time of the ventilation control window; If the second maximum execution time of the capacitor charging task is not greater than the target ventilation time of the ventilation control window, then it is determined whether the capacitor charging task has reached the preset target capacitor energy. If the capacitor charging task has reached the preset target capacitor energy, then the second completion state of the capacitor charging task is determined to be the charging completion state.

[0042] In one implementation, the second maximum execution time of the capacitor charging task is obtained through various methods. For example, the maximum time required for capacitor charging at different energy levels can be pre-stored, or the maximum execution time can be dynamically estimated by monitoring charging current and voltage in real time and combining the capacitor characteristic curve. Another approach is to perform calibration testing before the device leaves the factory, recording the longest charging time required to reach the preset target capacitor energy under various typical operating conditions, and storing this as a fixed parameter. Then, it is determined whether the second maximum execution time of the capacitor charging task is not greater than the target ventilation time within the ventilation control window. This is used to assess the time feasibility of the capacitor charging task and ensure it can be completed within the predetermined ventilation control window. For example, if the target ventilation time is 5 seconds and the second maximum execution time of the capacitor charging task is 4 seconds, the result is determined to be no greater than. Alternatively, a time margin can be set, i.e., determining whether the second maximum execution time plus a safety margin is not greater than the target ventilation time, to increase operational robustness.

[0043] Furthermore, if the second maximum execution time of the capacitor charging task is not greater than the target ventilation time of the ventilation control window, the system determines whether the capacitor charging task has reached the preset target capacitor energy. This is typically achieved by monitoring the voltage across the capacitor or the amount of stored charge. For example, the system can continuously sample the capacitor voltage and compare it with a preset target voltage threshold. When the voltage reaches or exceeds this threshold, the preset target capacitor energy is considered to have been reached. Another approach is to calculate the accumulated charge by integrating the change in charging current over time and comparing it with a preset charge threshold. If it is determined that the capacitor charging task has reached the preset target capacitor energy, the second completion state of the capacitor charging task is ultimately confirmed as the charging completion state. When the second maximum execution time of the capacitor charging task meets the time requirement and the capacitor itself has reached the preset target capacitor energy, the system can logically mark the task as a charging completion state. This is typically achieved by setting an internal status flag or variable, which is set to true when all conditions are met, indicating that the capacitor is ready for defibrillation discharge.

[0044] In this embodiment, by introducing a consideration of the time dimension of the capacitor charging task, the mechanism for determining defibrillation conditions is further improved. When performing the capacitor charging task, the maximum execution time under the most unfavorable conditions is obtained. This maximum execution time is then compared with the target ventilation time within the preset ventilation control window in the cardiopulmonary resuscitation (CPR) cycle. This ensures that the capacitor charging process can be completed within the ventilation control window, thus avoiding delays in defibrillation or conflicts with ventilation operations due to excessive charging time. Only when the second maximum execution time of the capacitor charging task is confirmed to be within the target ventilation time of the ventilation control window will the system further determine whether the capacitor has reached the preset target capacitor energy required for defibrillation. When both conditions—time feasibility and energy sufficiency—are met, the second completion state of the capacitor charging task is finally determined as the charging completion state. This scheme ensures that defibrillation operations can be performed promptly and efficiently within the specific safety window of the CPR cycle, allowing for optimal shock control at the optimal time, provided that a defibrillable rhythm is met, thereby improving the success rate of CPR defibrillation and the patient's chances of survival.

[0045] In one embodiment, prior to step S104, i.e. after the defibrillator is controlled to deliver an electric shock within a preset discharge time, the following steps are included: Obtain the ventilation action status of the ventilation control window; Determine whether the ventilation action status meets the preset safety requirements; If the ventilation action state meets the preset safety requirements, then the current time corresponding to the state that meets the preset safety requirements is taken as the preset discharge time, and the step of controlling the defibrillator to deliver an electric shock within the preset discharge time is executed.

[0046] In one implementation, a respiratory sensor monitors the patient's ventilation status within the ventilation control window in real time. This ventilation status can refer to the patient's physiological states such as inhalation, exhalation, breath-holding, and no breathing. The system can then preset one or more safe ventilation status thresholds or modes to determine whether the ventilation status meets the preset safety requirements. For example, when the amplitude of the respiratory signal is below a certain threshold, or when the respiratory cycle is at the end of expiration and the duration reaches a preset value, it is considered to meet the safety requirements. The preset safety requirements typically refer to the patient being relatively still, without obvious respiratory movements, or in a specific stage of the respiratory cycle. This setting helps to avoid unnecessary mechanical damage to the patient's airway or lungs from electric shock, while ensuring that the electric shock energy can be delivered to the target site efficiently and accurately. If the ventilation status meets the preset safety requirements, the defibrillator will immediately send a discharge command to the defibrillator and record the current system time as the preset discharge time. That is, the current time corresponding to the ventilation status meeting the preset safety requirements is used as the preset discharge time, and the defibrillator is controlled to deliver an electric shock within the preset discharge time.

[0047] In this embodiment, the defibrillator continuously acquires the patient's ventilation status within the ventilation control window and compares it with preset safety requirements. Only when the patient's ventilation status is determined to meet the preset safety requirements—for example, when the patient is in apnea or a specific safe phase of the respiratory cycle—will the system accurately determine the current moment corresponding to that safe status as the preset discharge time and immediately execute the electric shock control. By introducing a real-time assessment mechanism of the ventilation status on top of meeting the defibrillation conditions, the system ensures that the electric shock is performed at the moment when the patient's ventilation is most stable and safest. This mechanism effectively avoids the electric shock occurring when the patient is making violent breathing movements, thereby reducing the risk of electric shock energy attenuation, poor electrode contact, or additional damage to the patient's respiratory system that may be caused by respiratory movements. This further optimizes the safety and effectiveness of the electric shock, making the entire cardiopulmonary resuscitation defibrillation process more precise and reliable.

[0048] Please see Figure 2 , Figure 2 This is a schematic diagram of the control device of the defibrillator provided in an embodiment of the present invention. This control device corresponds one-to-one with the control method of the defibrillator in the above embodiments. Please refer to [link / reference] for details. Figure 1 as well as Figure 1 The relevant descriptions in the corresponding embodiments are shown below. For ease of explanation, only the parts relevant to this embodiment are shown. See also...
