[0002] In clinical medicine, the video laryngoscope is a commonly used auxiliary device to help doctors observe the laryngeal structure more clearly during procedures such as endotracheal intubation and laryngeal examinations. As a key consumable component of the video laryngoscope, the way the laryngeal blade connects to the handle directly affects the ease of use and reliability.

[0003] Currently, the connection between video laryngoscopes and laryngeal blades mostly uses a ball-bearing snap-fit ​​structure. This structure has the following problems during use:

[0004] 1. Mechanical wear issue: The ball bearing clips are prone to wear during frequent pressing and releasing. Over time, the size of the ball bearing clips gradually increases, resulting in insufficient locking force and inability to effectively secure the laryngeal blade, increasing the risk of clinical procedures.

[0005] 2. Inconvenient operation: The ball buckle requires the user to press hard to complete the installation or removal, which is a rather cumbersome process, especially in emergency situations, which may affect the efficiency of operation.

[0006] 3. Short service life: Due to the complex mechanical structure of the ball buckle, it is difficult to repair after wear, and usually the entire device needs to be replaced, which increases the cost of use.

[0007] Therefore, developing a novel laryngeal blade locking device to solve the problems of wear, inconvenience of operation, and short service life in existing technologies is of great clinical significance. Utility Model Content

[0008] The purpose of this invention is to provide a laryngeal lens locking device that is easy to install and disassemble, aiming to solve the problems of existing ball-load locking devices that fail to lock due to wear, are inconvenient to operate, and have a short service life.

[0009] To solve the above problems, the technical solution of this utility model is as follows:

[0010] A laryngeal lens locking device that is easy to install and remove includes a handle, a connector, and a laryngeal lens. The laryngeal lens includes a tubular head and a curved tail. The connector is fitted inside the handle, which is inserted into the head. A stepped hole is provided on one side of the handle. A keycap, an elastic diaphragm, and a spring are arranged sequentially from the outside to the inside of the stepped hole. The edge of the keycap is provided with a skirt that abuts against the stepped surface of the stepped hole. A through hole is provided on the laryngeal lens. The spring pushes one end of the keycap into the through hole through the elastic diaphragm.

[0011] Furthermore, the elastic diaphragm has a flange around its outer edge and a groove around its inner wall, with the flange inserted into the groove.

[0012] Furthermore, a boss is fixedly provided on the elastic diaphragm, and the boss is inserted into the spring.

[0013] Furthermore, a hemispherical recess is provided on the end face of the keycap.

[0014] Furthermore, a chamfer is provided on one edge of the keycap.

[0015] Furthermore, a chamfer is provided at the outer opening of the through hole.

[0016] Furthermore, the elastic diaphragm is a cap-shaped frustum that is thick in the middle and thin at the edges.

[0017] The beneficial effects of this utility model are as follows:

[0018] 1. Simple structure and easy operation: With the built-in spring and elastic diaphragm design, users can easily install and remove the laryngeal blade by simply pressing the keycap, without having to press the ball bearing forcefully, which greatly improves the convenience and efficiency of operation, and is especially suitable for emergency medical scenarios.

[0019] 2. No mechanical wear, long service life: Compared with traditional ball joints, this device uses elastic elements to achieve the locking function, avoiding mechanical wear problems. Under normal use conditions, the service life of the locking device is significantly extended, reducing the frequency of equipment replacement and operating costs.

[0020] 3. Secure locking and high reliability: The spring pushes the keycap through the elastic diaphragm, ensuring that the keycap can be tightly inserted into the through hole of the laryngoscope blade. The locking effect is stable and reliable, effectively preventing the laryngoscope blade from falling off during use and ensuring the safety of clinical operation.

[0021] 4. User-friendly design: The hemispherical concavity and chamfer design on the end face of the keycaps, as well as the special shape of the elastic membrane, give a clear sense of tactile feedback during operation. Users can intuitively feel the locking and unlocking states, which enhances the user experience.

[0022] In summary, this utility model provides a laryngeal lens locking device that is simple in structure, easy to operate, has a long service life, and is securely locked.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] like Figures 1 to 3 As shown, a laryngeal lens locking device that is easy to install and disassemble includes a handle 3, a connector 9, and a laryngeal lens 1. The laryngeal lens 1 includes a tubular head and a curved tail. The connector 9 is assembled inside the handle 3, and the handle 3 is inserted into the head. A stepped hole is opened on one side of the handle 3. A keycap 2, an elastic diaphragm 7, and a spring 8 are arranged sequentially from the outside to the inside in the stepped hole. The edge of the keycap 2 is provided with a skirt 6, which abuts against the stepped surface of the stepped hole. This can limit the keycap 2, allowing the keycap 2 to be moved only axially. A through hole 10 is opened on the laryngeal lens 1. The spring 8 pushes one end of the keycap 2 into the through hole 10 through the elastic diaphragm 7.

[0030] In its normal state, spring 8 is not compressed, and the height of keycap 2 is higher than the plane of handle 3. When installing the laryngeal lens 1, press keycap 2 to apply pressure to spring 8. The height of keycap 2 is lower than the plane of handle 3, allowing laryngeal lens 1 to be easily installed. After installation, release keycap 2, spring 8 returns to its original state, keycap 2 pops out and locks laryngeal lens 1, completing the locking process.

[0031] Detailed operating steps

[0032] 1. Install laryngeal blade:

[0033] Align the tubular head of the laryngeal blade 1 with the insertion end of the handle 3, ensuring that the through hole 10 on the laryngeal blade 1 is aligned with the stepped hole of the handle 3. Press the keycap 2 with your finger, causing it to move axially inward. At this time, the spring 8 is compressed, and the height of the keycap 2 is lower than the plane of the handle 3. With the keycap 2 pressed down, insert the tubular head of the laryngeal blade 1 into the handle 3 until the through hole 10 of the laryngeal blade 1 is aligned with the front end of the keycap 2. Release the keycap 2; the spring 8 returns to its original shape under the action of elastic force, pushing the keycap 2 outward, so that the front end of the keycap 2 is inserted into the through hole 10, completing the locking of the laryngeal blade 1.

[0034] 2. Remove the laryngeal blade:

[0035] Press keycap 2 repeatedly until its front end exits through hole 10. While keycap 2 is pressed down, gently pull out laryngeal blade 1 to complete disassembly.

[0036] Furthermore, a flange 5 is provided around the outer edge of the elastic diaphragm 7, and a groove is provided on the inner wall surface of the handle 3, into which the flange 5 is inserted. This ensures that the elastic diaphragm 7 will not shift during assembly, while also improving the sealing performance of the device and preventing dust or liquid from entering the stepped hole.

[0037] Furthermore, a boss 11 is fixedly provided on the elastic diaphragm 7, which is inserted into the spring 8 and is used to position the spring 8. This design ensures that the spring 8 remains stable during compression and extension, preventing the spring 8 from shifting or tilting within the stepped hole, thereby ensuring the reliability of the locking device.

[0038] Furthermore, a hemispherical recess is provided on the end face of the keycap 2. This structural design ensures that the elastic diaphragm 7 fits tightly against the keycap 2, reducing friction between them and extending their service life.

[0039] Furthermore, a chamfer is provided on one edge of the keycap 2. The chamfer design not only guides the keycap 2 to be smoothly inserted into the through hole 10, but also reduces wear on the throat lens 1 during installation, improving the durability of the device.

[0040] Furthermore, a chamfer is provided on the outer opening of the through hole 10. This makes pressing the keycap 2 smoother during installation and reduces operating resistance.

[0041] Furthermore, the elastic diaphragm 7 is shaped like a cap-shaped frustum, thicker in the middle and thinner at the edges. This design allows the elastic diaphragm 7 to evenly transmit the elastic force of the spring 8 when subjected to force, while deforming at the thinner edges to provide a clear tactile feedback, making it easier for users to perceive the pressing position of the keycap 2.

[0042] The embodiments described in this specification are merely examples of implementations of the inventive concept. The scope of protection of this utility model should not be considered as limited to the specific forms described in the embodiments. The scope of protection of this utility model also extends to equivalent technical means that can be conceived by those skilled in the art based on the inventive concept.
