Obviously, the drawings described below are only some embodiments of this application. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

Detailed Implementation

[0018] In the embodiments of this application, the terms "first," "second," "third," "fourth," "fifth," and "sixth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first," "second," "third," "fourth," "fifth," and "sixth" may explicitly or implicitly include one or more of that feature.

[0019] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0020] Combination Figure 1 As shown in the figure, this application embodiment provides a video laryngoscope system. The video laryngoscope 1 includes a video laryngoscope 1 and a management dock 2. The video laryngoscope 1 includes a first NFC module 11, a wireless charging receiving coil 12, and a first controller 13. The management dock 2 has a video laryngoscope 1 placement compartment, a second NFC module 22, a second wireless communication module, a wireless charging transmitting coil 22, and a second controller 23. When the first controller 13 is awakened by wireless charging information, the first controller 13 controls the first NFC module 11 to establish a first communication connection with the second NFC module 22. Under the trigger of the first communication connection, the second controller 23 controls the wireless charging transmitting coil 22 and the second NFC module 22 to perform time-sharing cyclic wireless charging and establish the first communication connection. During the first time window for establishing the first communication connection, the wireless charging transmitting coil 22 is controlled to stop working, and the second NFC module 22 receives the status information of the video laryngoscope 1 sent by the first NFC module 11. During the second time window for performing wireless charging, the wireless charging transmitting coil 22 is controlled to start, and the first communication connection is disconnected. The second controller 23 determines the wireless charging power for the next cycle based on the status information.

[0021] In this embodiment, the wireless charging transmitting coil 22 and the wireless charging receiving coil 12 have the same frequency, such as 100-205kHz in the Qi standard. In standby mode, the second controller 23 of the management dock 2 periodically sends a brief, low-energy detection pulse to the wireless charging transmitting coil 22. When the video laryngoscope 1 is not placed on the management dock 2, the energy of the detection pulse is slowly released in the coil because there is no wireless charging receiving coil 12 to absorb the energy. The second controller 23 detects the slow signal attenuation and determines that the current state is no-load. When the video laryngoscope 1 is placed on the management dock 2, the receiving coil enters the magnetic field range. At the moment the detection pulse is emitted, the energy is coupled and absorbed by the wireless charging receiving coil 12. At this time, the signal in the wireless charging transmitting coil 22 attenuates rapidly. The second controller 23 determines that the video laryngoscope 1 is placed on the management dock 2 by the signal attenuation rate.

[0022] To further prevent other metal objects placed on the management dock 2 from being misidentified and causing dangerous overheating, the second controller 23 applies an authentication power signal to the transmitting coil that is longer than the detection pulse duration. After the wireless charging receiving coil 12 absorbs the authentication power signal, it powers the first controller 13. The first controller 13 is awakened by wireless charging and can output a load modulation signal to modulate the load of the receiving coil circuit. After the transmitting coil receives the load change signal, it decodes it to confirm that the wireless charging transmitting coil 22 and the wireless charging receiving coil 12 are successfully coupled.

[0023] Simultaneously, the first controller 13 is awakened by wireless charging and controls the first NFC module 11 to establish a first communication connection with the second NFC module 22. After the first communication connection is established, the first controller 13 sends the status information of the video laryngoscope 1 to the management dock 2 through the first communication connection. The status information may include the remaining power of the video laryngoscope 1, the internal temperature of the video laryngoscope 1, and other information. After receiving the status information, the second controller 23 can determine the wireless charging power based on the status information.

[0024] In this embodiment, both NFC and Qi standard wireless charging are based on the principle of electromagnetic induction. They both transmit energy or signals through alternating magnetic fields. Although their base frequencies differ, high-power wireless charging circuits generate abundant high-frequency harmonic noise during operation. These harmonics easily fall within the 13.56MHz frequency band of NFC. Furthermore, wireless charging aims to transmit energy, requiring an extremely strong magnetic field. In contrast, NFC communication aims to transmit data, only needing a very weak magnetic field for short-range communication. When the coils of both are close together, the strong magnetic field generated by wireless charging can saturate the NFC receiving coil, preventing it from interpreting the minute signals it needs, leading to communication failure.

[0025] During wireless charging, the internal temperature of the video laryngoscope 1 will rise. Excessive internal temperature may reduce the lifespan of the video laryngoscope 1 or even damage it. In addition, different remaining power requires different charging power to protect the battery and extend its lifespan. Therefore, during wireless charging, the internal temperature and remaining power need to be sent to the management dock 2 for dynamic management of charging.

[0026] In order to transmit the status information of the video laryngoscope 1 to the docking station 2 and avoid communication failure caused by high-frequency harmonic noise from wireless charging, in this embodiment, the second controller 23 controls the wireless charging transmitting coil 22 and the second NFC module 22 to perform time-sharing cyclic wireless charging and establish the first communication connection. During the first time window for establishing the first communication connection, the wireless charging transmitting coil 22 is stopped, and the second NFC module 22 receives the status information of the video laryngoscope 1 sent by the first NFC module 11. During the second time window for performing wireless charging, the wireless charging transmitting coil 22 is activated, and the first communication connection is disconnected. The second controller 23 determines the wireless charging power for the next cycle based on the status information.

[0027] During wireless charging, a charging and communication cycle can be set, dividing one cycle into a first time window for transmitting status information only during the first communication connection and a second time window for wireless charging only. The first time window can be determined based on the amount of data to be transmitted and the communication rate of the first communication. For example, the first time window can be set to 100-200ms. For example, the establishment of the NFC radio frequency field is usually completed within 1-5ms, and the establishment of the NFC communication connection, i.e., device activation, is usually completed within 5-15ms. The standard communication rate of NFC is generally 106kbps, while the amount of data transmitted is usually less than 200 bytes. Therefore, setting the first time window to 100-200ms can ensure that the status information is transmitted completely.

[0028] Within the second time window, management dock 2 initiates wireless charging for high-power energy transfer. At this time, the first communication connection pauses data transmission. Within the second time window, management dock 2 actively pauses wireless charging transmission to eliminate electromagnetic interference. During this window, the video laryngoscope 1 quickly transmits key status information, such as internal temperature and real-time remaining charge, to management dock 2 via the first communication connection. Based on the status information received in the first time window, management dock 2 can dynamically adjust the charging power for the next cycle. For example, if the temperature is high, the charging power is reduced; if the remaining charge reaches a preset value, it can be charged at the corresponding charging power; for example, if the remaining charge reaches 90%, trickle charging is activated to protect the battery. This avoids electromagnetic interference issues caused by wireless charging, ensures absolute reliability of NFC communication, and achieves real-time monitoring of key safety parameters and safe charging while maintaining charging efficiency. System reliability is significantly improved; charging and communication can coexist stably, achieving safe and precise control of the charging process and preventing uncontrolled temperature rise due to communication interruptions.

[0029] In one embodiment, when the first controller 13 of the video laryngoscope 1 is activated, the first controller 13 can first obtain the current state information and generate an application strategy for the video laryngoscope 1 based on the current information. This application strategy may include wireless charging power, a first window duration, and a second window duration. The application strategy is then sent to the management dock 2 via the first communication connection, so that the management dock 2 executes the application strategy. In this embodiment, the application strategy can be sent to the management dock 2 when the first communication connection is established for the first time, or it can be sent to the management dock 2 within any first time window.

[0030] In one embodiment, generating an application strategy based on the status information includes: determining the wireless charging power based on the remaining battery power and / or the internal temperature, wherein the wireless charging power is inversely correlated with the remaining battery power and / or the internal temperature. After determining the wireless power, the duration of a second window can be determined based on the wireless charging power. Since a higher wireless power results in a faster internal heating rate for the laryngoscope 1, in order to ensure controllable temperature rise, in this embodiment, the second time window is shortened as the wireless charging power increases, and the frequency of transmitting status information is increased to ensure that the internal temperature of the laryngoscope can be transmitted to the management dock 2 in a timely manner, and the wireless charging power can be dynamically managed according to the internal temperature.

[0031] In one embodiment, the video laryngoscope 1 includes a first wireless communication module, and the management dock 2 includes a second wireless communication module. After the first communication connection is established, the second NFC module 22 sends the SSID and password of the second wireless communication module to the first NFC module 11. The first wireless communication module establishes a second communication connection with the second wireless communication module through the SSID and password, and transmits the laryngoscope data stored in the video laryngoscope 1 to the management dock 2 through the second communication connection.

[0032] The first wireless communication device includes a first WiFi module, and the second wireless communication device includes a second WiFi module. The first WiFi module and the second WiFi module can establish a wireless communication connection when triggered by the near-field communication connection established by the first NFC module 11 and the second NFC module 22.

[0033] In one embodiment, both the video laryngoscope 1 and the management dock 2 are equipped with WiFi and NFC modules. When the video laryngoscope 11 is placed in the management dock 2, the first NFC module 11 of the video laryngoscope 1 and the second NFC module 22 of the management dock 2 complete data information docking. After docking is completed, the WiFi module of the video laryngoscope 1 will automatically connect to the WiFi module of the management dock 2, and a network connection will be established between the video laryngoscope 1 and the management dock 2. In this embodiment, the method for WiFi network configuration based on the NFC module can refer to the existing network configuration methods.

[0034] For example, the process of configuring the first WiFi module and the second WiFi module for network access based on the near-field communication between the first NFC module 11 and the second NFC module 22 is as follows: When the first NFC module 11 approaches the second NFC module 22, the first NFC module 11 establishes near-field communication with the second NFC module 22, and the second NFC module 22 connects to the second WiFi module, enabling the second NFC module 22 to receive the SSID and password of the second WiFi module. After the first NFC module 11 and the second NFC module 22 establish near-field communication, the first NFC module 11 receives the SSID and password of the second WiFi module and transmits the SSID and password of the second WiFi module to the first WiFi module, thus establishing a wireless communication connection between the first WiFi module and the second WiFi module.

[0035] The management dock 2 receives data stored in the video laryngoscope 1 via Wi-Fi and forwards the video laryngoscope 1 data to the server 3 via an external communication device 24. In this embodiment, the server 3 can be a hospital server 3, which is equipped with an airway data management system. This system receives the video laryngoscope 1 data uploaded from the management dock 2, categorizes and saves the data according to the video laryngoscope 1 information, and authorized personnel can easily view all the video laryngoscope 1 data through a browser. The airway data management system can also associate the uploaded video laryngoscope 1 data with medical record numbers, allowing patients to be located through the hospital's HIS system.

[0036] In one embodiment, the application strategy of the video laryngoscope 1 system described above may rely on manual settings or single-condition judgments, lacking a deep understanding of the overall operating environment. This results in an inability to adaptively adjust to the dynamic needs of actual usage scenarios, such as emergency resuscitation, routine surgery, and overnight storage. It is also difficult to perform targeted charging management for different usage scenarios. For example, in an emergency resuscitation scenario, charging at the normal usage power may result in insufficient power when needed. Similarly, in maintenance scenarios, such as nighttime or weekends when there is no usage demand, frequent high-power charging may reduce battery life. Therefore, it is essential to adapt to dynamic needs and adjust the charging power adaptively according to the applicable scenario.

[0037] Specifically, the status information also includes usage scenario information for the video laryngoscope 1, and the generation of application strategies based on the status information includes: The second controller 23 determines the current working mode of the video laryngoscope 1 based on the usage scenario information, and adjusts the wireless charging power based on the working mode; wherein, the different working modes correspond to different levels of urgency, and the level of urgency is positively correlated with the wireless charging power.

[0038] In this embodiment, corresponding wireless charging power can be set specifically for different usage scenarios. After determining the initial wireless charging power based on internal temperature and remaining battery power, the current working mode can be determined through usage scenario information, and the initial wireless charging power can be adjusted based on the wireless charging power corresponding to the working mode. For example, the usage scenario information may include predefined scenario tags; the generation of application strategies based on the status information includes: after receiving the predefined scenario tag, the second controller 23 determines the predefined working mode corresponding to the predefined scenario tag based on the predefined scenario tag; and adjusts the wireless charging power according to the set charging power corresponding to the predefined working mode.

[0039] For example, tag information corresponding to different usage scenarios can be pre-written into the video laryngoscope 1. For instance, in the emergency room, the video laryngoscope 1 can be written with emergency room tag information, and in the general anesthesiology department, it can be written with general anesthesiology department tag information. Additionally, the usage scenario can be determined by the placement time. For example, placing it during weekday daytime determines the usage scenario as urgent, generating a tag for urgent use; placing it at night or on weekends determines the usage scenario as no need, generating a tag for no need. After receiving the tag information corresponding to the usage scenario, the management dock 2 parses the tag information to obtain the required operating mode, and then adjusts the initial wireless charging power accordingly. This allows for adaptive and dynamic adjustment of the charging power for different usage scenarios.

[0040] To further meet usage requirements, this embodiment can also combine multimodal data to accurately identify usage scenarios. The usage scenario information also includes multi-source dynamic scene features, where each type of dynamic scene feature corresponds to a predefined working mode. The second controller 23 determines the working mode score of the video laryngoscope 1 based on the predetermined scene label and the multi-source dynamic scene features; the working mode with the highest score is taken as the current working mode of the video laryngoscope 1, and the wireless charging power is adjusted based on the current working mode. By fusing multi-source information, the video laryngoscope 1 system can automatically identify the current scenario and make optimal intelligent decisions.

[0041] For example, the first controller 13 can first collect multi-source data. In this embodiment, after the first controller 13 is woken up, it can collect real-time status data at the time of wake-up, such as remaining power and internal temperature; time-series characteristic data, such as the absolute time of being woken up by wireless charging, whether it is a weekday or weekend, and the moment of being woken up by wireless charging; and historical usage patterns, such as the historical average number of times used per day and peak usage periods.

[0042] The collected raw data is transformed into feature vectors to obtain multi-source dynamic scene features. For example, in this embodiment, the multi-source dynamic scene features may include department features, time period features, power consumption features, and historical usage features. In this embodiment, different levels of urgency can be determined for different features, and this urgency level is used as the weight for the work mode scoring. For example, department features may include the emergency department (corresponding urgency quantification value A1), anesthesiology department (corresponding urgency quantification value A2), ICU (corresponding urgency quantification value A3), and others (corresponding urgency quantification value A4). The values ​​of A1 to A4 gradually decrease, indicating a gradual decrease in urgency quantification. Time period features may include weekday daytime (corresponding urgency quantification value B1), weekday evening (corresponding urgency quantification value B2), and weekend (corresponding urgency quantification value B3), where the values ​​of B1 to B3 gradually decrease, indicating a gradual decrease in urgency quantification. Battery level characteristics include different remaining battery level ranges. For example, a remaining battery level of less than 20% corresponds to an urgency level quantification value of C1; a remaining battery level of more than 20% but less than 80% corresponds to an urgency level quantification value of C2; and a remaining battery level of more than 80% corresponds to an urgency level quantification value of C3. The values ​​of C1 to C3 gradually decrease, indicating a decreasing urgency level quantification value. Historical usage characteristics may include usage frequency, with different urgency level quantification values ​​corresponding to different usage frequencies; the higher the usage frequency, the higher the urgency level quantification value.

[0043] When scoring the working mode based on multi-source dynamic scene features, the multi-source dynamic scene features of the current video laryngoscope 1 can be analyzed. The sum of the urgency quantification values ​​corresponding to each feature is used as the working mode score of the video laryngoscope 1. The higher the working mode score, the greater the corresponding wireless charging power. The wireless charging power is determined based on the working mode score, enabling more precise and dynamic application to different usage scenarios.

[0044] In one embodiment, when the management dock 2 stops charging the video laryngoscope 1, it records the charging data of the video laryngoscope 1 and transmits the charging data to the server 3. The charging data includes the remaining battery level, the start time of charging, and the stop time of charging. Based on the charging data, the server 3 sends the wireless charging power adjustment information of the video laryngoscope 1 for the next charge to the management dock 2, so that the management dock 2 can adjust the wireless charging power. Different charging data correspond to different usage needs. For example, removing the video laryngoscope 1 when it is not fully charged indicates that the video laryngoscope 1 is urgently needed. Removing the video laryngoscope 1 when it is fully charged may indicate that the need for using the video laryngoscope 1 is not strong. Therefore, the server 3 can adjust the charging power of the video laryngoscope 1 for the next charge based on the charging data of the currently removed video laryngoscope 1 to meet different usage scenarios and extend battery life.

[0045] For example, in the emergency department, there are multiple video laryngoscopes 1. When a video laryngoscope 1 is being charged, it is charged from a state where the remaining power is less than 20% until it is not fully charged and is then taken away. Afterwards, a second video laryngoscope 1 continues to charge. After obtaining the charging data, the server 3 can also synchronously obtain the ID information of each video laryngoscope 1. Based on the ID information of the video laryngoscope 1, the association between the two video laryngoscopes 1 that are being charged before and after is determined. If they belong to the same department and are taken away before a video laryngoscope 1 is fully charged, then the current scenario is confirmed to be an emergency scenario, and a video laryngoscope 1 is urgently needed. Therefore, adjustment information can be output to adjust the charging power of the next video laryngoscope 1 with the association to the maximum, so as to quickly charge the next video laryngoscope 1 and thus meet the needs of the emergency scenario.

[0046] In another exemplary embodiment, if the video laryngoscope 1 is charged at the standard charging power or a lower charging power and is removed after being fully charged, it indicates that there is no urgent need for its use. Therefore, the video laryngoscope 1 can be charged at the standard charging power for the next charging cycle. This reduces battery wear and extends battery life while ensuring applicability to the current scenario.

[0047] In the description of the embodiments of this application, specific features, structures, materials or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0048] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
