[0002] As a key medical device for endotracheal intubation in anesthesiology, emergency medicine, and intensive care units, the clarity of the laryngoscope lens directly affects the success of the procedure and patient safety. In actual clinical application, because the patient's exhaled air is warm and humid, it easily condenses and forms fog on the laryngoscope lens when it comes into contact with the lens at room temperature, resulting in blurred vision, which in turn prolongs intubation time, increases the difficulty of the procedure, and increases the risk of complications.

[0003] However, existing testing equipment and methods cannot simulate real fogging conditions, the testing process is less standardized, and the accuracy of the test results is low. Utility Model Content

[0034] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0035] As a crucial medical device for endotracheal intubation in anesthesiology, emergency medicine, and intensive care units, the clarity of the laryngoscope lens directly affects the success of the procedure and patient safety. In actual clinical applications, because the patient's exhaled air is warm and humid, it easily condenses and fogs on the laryngoscope lens surface when it comes into contact with the lens at room temperature, leading to blurred vision, prolonged intubation time, increased operational difficulty, and higher risk of complications. However, existing testing devices and methods cannot simulate real fogging conditions, the testing process is less standardized, and the accuracy of the test results is relatively low.

[0036] Based on this, please refer to Figures 1-4The laryngoscope blade testing device 1000 provided in this embodiment can effectively solve the aforementioned technical problems. The laryngoscope blade testing device 1000 in this embodiment can simulate real fogging conditions, ensuring the accuracy and reliability of the test, and also ensuring the consistency and comparability of test results between different batches and different models of laryngoscope systems 2000.

[0037] Figure 1 This is a schematic diagram of a laryngoscope blade testing device 1000 equipped with a laryngoscope system 2000 provided in an embodiment of the present invention. Figure 2 This is a schematic diagram of the laryngeal blade testing device 1000 provided in an embodiment of the present invention; Figure 3 This is a schematic diagram from a first-view perspective of the laryngeal blade testing device 1000 for removing the test card 400 provided in an embodiment of the present invention. Figure 4 This is a schematic diagram from a second perspective of the laryngeal blade testing device 1000 for removing the test card 400 provided in an embodiment of the present invention.

[0038] Please see Figures 1-4 The laryngoscope lens testing device 1000 in this embodiment includes a support platform 100, an atomizer 200, a clamping mechanism 300, and a test card 400. The support platform 100 has a cavity 110. The atomizer 200 provides spray to the cavity 110. The clamping mechanism 300 is disposed on the support platform 100 and clamps the laryngoscope system 2000. The test card 400 is housed within the cavity 110 and has a spray hole 410 that communicates with the cavity 110. After the laryngoscope system 2000 is installed and fixed to the clamping mechanism 300, the atomizer 200 is turned on, and the mist can be sprayed onto the laryngoscope lens through the spray hole 410, thus facilitating the testing of the laryngoscope lens's anti-fog performance.

[0039] The laryngoscope blade testing device 1000 can simulate the real-world conditions of a laryngoscope system 2000 during clinical use, where the blade is exposed to the warm, humid environment of the patient's oral cavity and is susceptible to fogging from droplets or aerosols. This allows for testing the anti-fogging performance of the laryngoscope blade, making the test results more accurate and reliable. The clamping mechanism 300 ensures that the laryngoscope system 2000 is firmly and repeatedly fixed in the same position, allowing the laryngoscope blade to be precisely aligned with the center area of ​​the spray nozzle 410 each time. This eliminates test variables caused by manual handling or different installation positions, effectively ensuring the consistency and comparability of test results between different batches and models of laryngoscope systems 2000. Furthermore, the integration of the support platform 100, nebulizer 200, and clamping mechanism 300 into a single unit constitutes a standardized platform specifically for laryngoscope blade testing. Users only need to place the test card 400, install the laryngoscope system 2000, and start the nebulizer 200 to begin the test, which greatly simplifies the operation process, reduces the technical requirements for operators, helps improve testing efficiency, and can meet the needs of batch and repetitive testing.

[0040] In this embodiment, the cavity 110 can be formed by machining a groove within the solid structure of the support platform 100. This groove recesses downwards from the upper surface of the support platform 100, allowing the cavity 110 to be entirely submerged within the support platform 100. Alternatively, the cavity 110 can be formed by a box structure disposed on the upper surface of the support platform 100. The box has a predetermined internal space to form the cavity 110, and its bottom is connected to the upper surface of the support platform 100. Depending on different application requirements, parts of the box structure can protrude above the support platform 100, or the entire box structure can be located above the support platform 100.

[0041] Please see Figure 1 and Figure 2 To facilitate the replacement and maintenance of the test card 400, in this embodiment, the test card 400 is detachably connected to the support platform 100. The test card 400 can be connected to the support platform 100 via threaded fasteners, or detachably connected to the support platform 100 via clips or other means, which are not limited here. Alternatively, the test card 400 can simply be held in place by the cavity 110.

[0042] To facilitate the removal of the test card 400, the support platform 100 in this embodiment has a card removal hole 120, which is located on the edge of the test card 400. Of course, to facilitate the removal of the test card 400, a recessed platform structure lower than the test card 400 or a push-out mechanism can also be used, which is not limited here.

[0043] Please see Figure 4The laryngeal lens testing device 1000 in this embodiment also includes a conduit 500; the cavity 110 is provided with a through hole 130 communicating with the conduit 500, and the atomizer 200 provides spray to the cavity 110 through the conduit 500. In this embodiment, the through hole 130 is provided on the side of the cavity 110 away from the test card 400, and the atomizer 200 is connected to the through hole 130 through the conduit 500.

[0044] Please see Figures 1-3 In this embodiment, the spray orifice 410 and the through hole 130 are coaxially arranged, and the diameter of the spray orifice 410 is not smaller than the diameter of the through hole 130. The coaxiality of the spray orifice 410 and the through hole 130 ensures that the gas flow path is on the same straight line, effectively avoiding turbulence, eddies, and unnecessary pressure loss caused by the offset of the flow channel axis. At the same time, the diameter of the spray orifice 410 is not smaller than the diameter of the through hole 130, further eliminating any possible step-like contraction in the flow channel, allowing the fluid to pass smoothly and stably, providing a foundation for forming a stable and uniform spray.

[0045] In addition, the atomizer 200 in this embodiment is an ultrasonic atomizer 200. Of course, other types of atomizers 200 can also be selected, which are not limited here.

[0046] In other embodiments, the atomizer 200 may be disposed within the cavity 110, and after the atomizer 200 generates mist within the cavity 110, it is sprayed directly from the spray hole 410 on the test card 400.

[0047] Please see Figures 1-3 In this embodiment, the clamping mechanism 300 includes a first fixing frame 310, a second fixing frame 320, a bracket 330, a first fixing member 340, and a second fixing member 350. The first fixing frame 310 and the second fixing frame 320 are spaced apart on the support platform 100. One end of the bracket 330 is connected to the first fixing frame 310 via the first fixing member 340, and the other end of the bracket 330 is connected to the second fixing frame 320 via the second fixing member 350. The bracket 330 is used to clamp and fix the laryngoscope system 2000.

[0048] Please continue reading. Figures 1-3In this embodiment, the first fixing bracket 310 has a first strip hole 311, the second fixing bracket 320 has a second strip hole 321, and the bracket 330 has threaded holes at both ends. The first fixing member 340 and the second fixing member 350 are shoulder screws. The first fixing member 340 passes through the first strip hole 311 and is screwed to one end of the bracket 330, and the second fixing member 350 passes through the second strip hole 321 and is screwed to one end of the bracket 330. By adjusting the screwing length between the first fixing member 340 and / or the second fixing member 350 and the bracket 330, the connection state between the bracket 330 and the first fixing bracket 310 can be switched between a fixed connection state and a movable connection state. In the movable connection state, the first fixing member 340 and / or the second fixing member 350 can move along the extension direction of the first strip hole 311 and / or the second strip hole 321, thereby adjusting the position of the bracket 330 relative to the first fixing bracket 310 and the second fixing bracket 320. Of course, the first fixing member 340 and the second fixing member 350 in this embodiment can also be other fixing members such as bolts, screws, screws or pins, which are not limited here.

[0049] Specifically, in this embodiment, the first fixing frame 310 has a first strip-shaped hole 311 extending vertically, and the second fixing frame 320 has a second strip-shaped hole 321 extending vertically. The bracket 330 engages with the first strip-shaped hole 311 via a first fixing member 340, and with the second strip-shaped hole 321 via a second fixing member 350. The first fixing member 340 and the second fixing member 350 can move vertically and lock within their respective first and second strip-shaped holes 311 and 321, thereby achieving height adjustment of the bracket 330 relative to the support platform 100. In this embodiment, the bracket 330 can move vertically relative to the first fixing frame 310 and the second fixing frame 320. By allowing the bracket 330 to move vertically relative to the two fixing frames, stepless and continuous adjustment of the installation height of the laryngoscope system 2000 is achieved. This design allows operators to precisely position the laryngeal blade at the optimal testing height according to the specific geometry of different types and models of laryngeal endoscope systems 2000 and their blades, thus expanding the versatility and application range of the laryngeal blade testing device 1000.

[0050] Of course, the first strip hole 311 and the second strip hole 321 can also extend along the horizontal movement direction, or strip holes extending along both the vertical and horizontal movement directions can be provided simultaneously to adjust the position of the bracket 330 in multiple directions.

[0051] To ensure the bracket 330 remains stable during movement, the cross-sectional shapes of the first slot 311 and the second slot 321 match the shapes of the first fixing member 340 and the second fixing member 350; the specific shapes are not limited here. The first slot 311 and the second slot 321 provide precise guidance for the movement of the bracket 330. The first fixing member 340 and the second fixing member 350 can move and lock at any position within the full length of the slot, realizing stepless and continuous adjustment of the bracket 330 in the height and / or horizontal direction. Furthermore, this structure is simple, reduces costs, and is easy to assemble.

[0052] Please see Figure 3 In this embodiment, the bracket 330 has a mounting groove 331 for supporting and fixing the handle of the laryngoscope system 2000. The shape of the mounting groove 331 is adapted to the outer surface shape of the handle of the laryngoscope system 2000, which can stably support the handle of the laryngoscope system 2000. The operator only needs to place the handle of the laryngoscope system 2000 into the groove to complete the initial centering and positioning in the horizontal plane, without having to repeatedly adjust the front-back and left-right position of the handle on the bracket 330. This greatly simplifies the clamping steps, shortens the operation time, and improves the testing efficiency. The mounting groove 331 provides a reliable support base for the handle of the laryngoscope system 2000, increases the contact area between the bracket 330 and the handle, significantly enhances the overall rigidity and stability of the clamping, and effectively prevents the laryngoscope system 2000 from slight shaking or rotation during the test.

[0053] Furthermore, the bracket 330 can also be movably connected to the first fixed bracket 310 and the second fixed bracket 320 via a linear drive mechanism, such as a guide rail slider, etc., which is not limited here. The clamping mechanism 300 can also be designed in other structural forms, as long as it can clamp and fix the laryngeal blade, which is not limited here.

[0054] In addition, to test the heat-fogging performance of the laryngeal lens, the laryngeal lens testing device 1000 in this embodiment also includes a fog heater 600. The fog heater 600 is disposed between the atomizer 200 and the support platform 100 and is used to heat the spray emitted by the atomizer 200. Specifically, the fog emitted by the atomizer 200 is directed to the fog heater 600 through a first section of pipe, and after being heated by the fog heater 600, the fog is directed to the cavity 110 through a second section of pipe.

[0055] In addition, the support platform 100 is equipped with at least one control button 700, which is electrically connected to the atomizer 200 and used to control the start and stop of the atomizer 200; and / or, the control button 700 is electrically connected to the mist heater 600 and used to control the start and stop of the mist heater 600. Integrating the control button 700 onto the support platform 100 allows operators to directly and quickly control the start and stop of the atomizer 200 and the heater, facilitating simultaneous control during observation. This integrated, one-piece design concentrates the core control functions in the most easily accessible location, greatly simplifying the operation process and shortening test preparation time. It is particularly suitable for test sequences requiring frequent start and stop operations, significantly improving test efficiency and user experience. Electrical signal control via the button enables remote low-voltage control of the high-pressure atomizer 200 or the high-temperature heater, eliminating the need for operators to directly contact the high-voltage wiring or high-temperature components, thus improving equipment safety. Indicator lights or audible prompts can be installed on the support platform 100 to clearly indicate whether commands have been executed. Instant feedback (such as indicator lights, touch, or sound) ensures that commands are executed accurately, avoiding energy waste or equipment overload caused by continuous operation due to misoperation.

[0056] The laryngeal lens testing device 1000 can perform clarity testing, anti-fogging performance testing, and anti-heat fogging performance testing on laryngeal lenses.

[0057] When performing clarity testing, the ambient temperature should be between 23±5℃ and the humidity between 60% and 80%, with no wind. The laryngoscope blade to be tested should be left to stand in this environment for 30 minutes. Insert the laryngoscope blade into the appropriate handle of the video laryngoscope system 2000 and place the handle of the laryngoscope system 2000 in the slot of the clamping mechanism 300. Turn on the switch of the video laryngoscope system 2000, observe whether the effective image area of ​​the test card 400 is within the viewing window, read the clarity level of the laryngoscope blade to determine whether it is qualified, and record it by taking a picture.

[0058] For anti-fog performance testing, the ambient temperature should be between 23±5℃, the humidity between 60% and 80%, and there should be no wind. The laryngoscope blade to be tested should be placed in this environment for 30 minutes. The laryngoscope blade should be inserted into the appropriate handle of the video laryngoscope system 2000, and the handle should be placed in the slot of the clamping mechanism 300. The video laryngoscope system 2000 should be turned on, and the effective image area of ​​the test card 400 should be observed within the viewing window. The spray button should then be pressed. The testing device will then spray the laryngoscope blade's viewing window for 10 seconds. After the spraying is complete, the clarity level of the laryngoscope blade should be read to determine whether it passes the test, and the result should be recorded by taking a photograph.

[0059] For the anti-heat fog performance test, the ambient temperature should be between 23±5℃ and 60%~80%, with no wind. The laryngoscope blade to be tested should be placed in this environment for 30 minutes. The laryngoscope blade should be inserted into the appropriate handle of the video laryngoscope system 2000, and the handle should be placed in the slot of the clamping mechanism 300. The video laryngoscope system 2000 should be turned on, and the effective image area of ​​the test card 400 should be observed within the viewing window. The heat fog spray button should then be pressed. At this time, the testing device will spray heat fog onto the viewing window of the laryngoscope blade for 10 seconds. After the heat fog spraying is complete, the clarity level of the laryngoscope blade should be read to determine whether it passes the test, and the result should be recorded by taking a picture.

[0060] The type of test card, ambient temperature and humidity, settling time, spraying time and heating time can all be adjusted according to the actual experimental conditions, and are not limited here.

[0061] In summary, the laryngoscope lens testing device 1000 includes a support platform 100, a nebulizer 200, a clamping mechanism 300, and a test card 400. The support platform 100 has a cavity 110; the nebulizer 200 provides spray to the cavity 110; the clamping mechanism 300 is located on the support platform 100 and clamps the laryngoscope system 2000; the test card 400 is housed within the cavity 110 and has a spray hole 410 that communicates with the cavity 110. This laryngoscope lens testing device 1000 can simulate the actual clinical conditions of the laryngoscope system 2000, where the lens is in a warm and humid environment in the patient's oral cavity and is easily exposed to droplets or aerosols, leading to fogging. This allows for testing the anti-fogging performance of the laryngoscope lens, making the anti-fogging performance test results more accurate and reliable. The clamping mechanism 300 ensures that the laryngoscope system 2000 is firmly and repeatedly fixed in the same position, so that the laryngoscope blade can be accurately aligned with the center area of ​​the spray hole 410 each time. This eliminates test variables caused by manual holding or different installation positions each time, and effectively ensures the consistency and comparability of test results between different batches and different models of laryngoscope systems 2000.

[0062] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
