Description

Technical Field

[0001] This utility model relates to the field of video laryngoscopes, and more specifically, it relates to a protective device for the end of a video laryngoscope. Background Technology

[0002] Laryngoscopy is very common in medical procedures. Due to the deep location and complex physiological structure of the larynx, it cannot be directly visualized. Special examination methods are required for larynx examinations. Therefore, video laryngoscopes are needed to visualize the appearance of the larynx. Existing video laryngoscopes generally consist of a display screen, a handle, and a tongue depressor. A camera is installed on the tongue depressor to capture images of the larynx and transmit them back to the display screen, thus enabling the imaging of the larynx. Because the camera and other components are precision structures, the entire machine is frequently removed and placed back during the use of video laryngoscopes. Since the tongue depressor is located at the bottom of the machine, it is easy for the camera to bump against the table or other surfaces, which can affect the long-term use of the laryngoscope. In addition, since different laryngoscopes have different tongue depressor lengths, it is impossible to protect the tongue depressor of the laryngoscope in the same way, thus affecting the use of the laryngoscope.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a protective device for the tip of a video laryngoscope, which has the following beneficial effects:

[0017] 1. This utility model, by setting a fixing structure, when fixing the main body shell and the tongue depressor plate, the main body shell is fitted onto the tongue depressor plate. By rotating the adjusting rod, the fixing block is driven to extend out of the main body shell through the threaded connection between the adjusting rod and the mounting bracket, thereby making contact between the fixing block and the main body shell. Thus, the tongue depressor plate and the main body shell are fixed together through the cooperation of multiple fixing blocks, which makes it easy to install the entire protective device on the tongue depressor plate of the laryngoscope, and thus facilitates the installation and disassembly of the entire protective structure.

[0018] 2. This utility model, through the setting of a connection structure, when assembling the entire protective structure, when connecting the intermediate shell and the main shell, the first mounting ring on the intermediate shell contacts the main shell, aligning the extension block on the first mounting ring with the extension block on the main shell. Pressing the limiting piece compresses the spring, causing the fixing rod to move. The fixing rod and the protruding block pass through the through hole and through groove on the first mounting ring and the through hole and through groove on the extension block on the main shell in sequence, causing the protruding block to extend out of the through groove. Rotating the fixing rod aligns the protruding block with the notch, releasing the pressure on the limiting piece, and the spring's own elasticity causes the fixing rod to rise, thereby causing the protruding block to enter the notch, connecting the intermediate shell and the main shell. This facilitates the connection between the main shell and the intermediate shell, and between the intermediate shells, thus facilitating the lengthening of the entire protective structure and adapting to tongue plates of different lengths.

[0019] 3. This utility model, by setting mounting pieces on the cover plate and the intermediate shell, connects the cover plate and the intermediate shell by using mounting holes and bolts to connect the mounting pieces, thereby connecting the cover plate and the intermediate shell. This facilitates the assembly and disassembly of the protective device, thereby increasing the applicability of the entire protective device. Attached Figure Description

[0032] More specifically, the entire device is connected to the tongue depressor through a fixing structure, and the connecting structure facilitates the connection between the main shell 1 and the intermediate shell 2, and between the intermediate shells 2 and each other.

[0033] Please see Figures 1-5As one embodiment of the assembly and installation of the protective device: the mounting bracket 6 is fixedly mounted on the main body shell 1, the adjusting rod 4 is mounted on the fixing block 5 and is rotatably connected to the fixing block 5, the adjusting rod 4 is threaded, the adjusting rod 4 passes through the mounting bracket 6, and the adjusting rod 4 is threadedly connected to the mounting bracket 6, the main body shell 1, the first mounting ring 10 and the second mounting ring 11 are all fixedly mounted with extension blocks 12, the extension blocks 12 on the first mounting ring 10 are mounted with extension frames 13, the extension blocks 12 and the extension frames 13 are all provided with through holes 14 for the fixing rod 7 to cooperate with, multiple springs 9 and limiting plates 8 are provided, the top ends of the limiting plates 8 and the fixing rod 7 are both provided with threads, the limiting plates 8 and the fixing rod 7 are threadedly connected, the springs 9 are sleeved and mounted on the fixing rod 7, the springs 9 are located between the limiting plates 8 and the extension frames 13, the top end of the fixing rod 7 is fixedly provided with a protruding block 15, the main body shell 1, the first mounting ring 10 and the second mounting ring 11 are all fixedly mounted with extension blocks 12, the extension blocks 12 are fixedly mounted with extension blocks 12, the extension blocks 12 and the first mounting ring 10 are all ... On the extension block 12 of the mounting ring 11, there are mating grooves 16 at both ends of the through hole 14. The mating grooves 16 and the through hole 14 are mutually engaged. On the extension block 12 of the main shell 1 and the second mounting ring 11, there are notches 17 at the positions where the mating grooves 16 are not provided. The notches 17 and the protruding blocks 15 are mutually engaged. There are multiple notches 17.

The limiting piece 8 is pressed, thereby compressing the spring 9 and causing the fixing rod 7 to move. This allows the fixing rod 7 and the protruding block 15 to pass sequentially through the through hole 14 and through groove on the first mounting ring 10, and through the through hole 14 and through groove on the extension block 12 on the main shell 1, causing the protruding block 15 to... 5. Extend through the slot, rotate the fixing rod 7 to align the protruding block 15 with the notch 17, release the pressure on the limiting piece 8, and the spring 9's own elastic force drives the fixing rod 7 to rise, thereby allowing the protruding block 15 to enter the notch 17, connecting the intermediate shell 2 and the main shell 1, thus facilitating the connection between the main shell 1 and the intermediate shell 2, and between the intermediate shell 2 and the intermediate shell 2. When connecting the cover plate and the intermediate shell 2, the mounting piece 20 is connected to the mounting piece 20 through the cooperation of the mounting hole 21 and the bolt, connecting the cover plate and the intermediate shell 2.

[0037] When fixing the main body shell 1 to the tongue depressor, the main body shell 1 is fitted onto the tongue depressor. The adjusting rod 4 is rotated, and through the threaded connection between the adjusting rod 4 and the mounting bracket 6, the fixing block 5 is driven to extend out of the main body shell 1, so that the fixing block 5 and the main body shell 1 come into contact. Thus, the tongue depressor and the main body shell 1 are fixed together by the cooperation of multiple fixing blocks 5, so that the entire protective device can be installed on the tongue depressor of the laryngoscope.
