Detailed Implementation
[0023] This utility model provides an adjustable endoscope mouthpiece. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following detailed description is provided with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining this utility model and are not intended to limit this utility model.
[0024] Please see Figures 1 to 5 As shown, this utility model provides an adjustable endoscope mouthpiece, including a mouthpiece 1, a tongue depressor 2, a baffle 3, and an elastic band 4. The mouthpiece 1 includes an upper piece 5, a lower piece 6, and several telescopic rods 7 for connecting the upper piece 5 and the lower piece 6. The baffle 3 is fixed to one end of the upper piece 5. The elastic band 4 is connected to both sides of the baffle 3. The tongue depressor 2 is located at the bottom of the lower piece 6 and its position can be adjusted along the length of the lower piece 6.
[0025] Before use, adjust the height of the multiple telescopic rods 7 and the insertion length of the tongue depressor 2 according to the size of the patient's mouth. Then, insert the bite body 1 into the patient's mouth, ensuring the baffle 3 contacts the patient's lips. Finally, place the elastic band 4 over the patient's head to prevent the bite body 1 from detaching from the patient's mouth. Compared to existing technologies, such as... Figure 1 , 2 As shown, the mouthpiece diameter and the position of the tongue depressor 2 can be adjusted to meet the needs of different users.
[0026] In a preferred embodiment, see [reference] Figure 4The telescopic rod 7 includes an adjusting rod 71 fixed to the lower piece 6, a sleeve rod 72 fixed to the upper piece 5, and a positioning block 73 slidably mounted on the sleeve rod 72. The sleeve rod 72 is slidably connected to the adjusting rod 71. The adjusting rod 71 has a guide groove 711 along its length and several slots 712 communicating with the guide groove 711. The guide groove 711 and the slots 712 are perpendicular to each other. The positioning block 73 moves along the guide groove 711 and can be translated into any slot 712 to lock the position of the sleeve rod 72. During adjustment, the positioning block 73 moves within the guide groove 711, allowing adjustment of the position of the sleeve rod 72 on the adjusting rod 71 to increase or decrease the total height of the telescopic rod 7. After adjusting to a suitable height, the positioning block 73 is pushed into the corresponding slot 712 to lock the position of the sleeve rod 72 on the adjusting rod 71.
[0027] In this embodiment, there are three slots 712, which can achieve three different height adjustments, thereby providing three different diameters for patients to use and meeting different usage needs.
[0028] To improve the stability of the connection between the upper piece 5 and the lower piece 6, and to ensure that the bite body 1 can withstand the pressure exerted by the patient's mouth, refer to... Figure 3 There are four telescopic rods 7, and each pair of telescopic rods 7 is used to connect one side of the upper piece 5 and one side of the lower piece 6, so that the bite body 1 has a stable frame structure.
[0029] Preferably, the telescopic rod 7 has a rectangular cross-section and its length extends along the length direction of the bite body 1. This ensures that the telescopic rod 7 has sufficient strength while avoiding excessive occupation of the space inside the bite body 1, thereby reducing the range of motion of the endoscope tube.
[0030] In a preferred embodiment, see [reference] Figure 4 The sleeve 72 has a horizontal groove 721. The positioning block 73 includes a sliding part 731 that is slidably connected to the horizontal groove 721. One side of the sliding part 731 has an insertion part 732 that is slidably connected to the guide groove 711. The thickness of the insertion part 732 matches the width of the slot 712. The other side of the sliding part 731 has a lever 733. The horizontal groove 721 limits the horizontal movement of the sliding part 731, allowing the insertion part 732 to slide smoothly from the guide groove 711 into the slot 712. Since the thickness of the insertion part 732 matches the width of the slot 712, the upper and lower sides of the insertion part 732 abut against the inner sides of the slot 712, respectively, thus locking the position of the sleeve 72. In addition, the lever 733 facilitates medical personnel to push the positioning block 73 into the slot 712.
[0031] Preferably, the end of the slot 712 is chamfered to further facilitate the insertion part 732 sliding into the slot 712.
[0032] Further, see Figure 4 , 5 The paddle 733 is rotatably connected to the sliding part 731. A limiting strip 734 is provided on the side of the paddle 733 near the slot 712. Under the action of the limiting strip 734, the paddle 733 can only rotate 90° towards the baffle 3. When the paddle 733 abuts against the limiting strip 734, it facilitates pushing the positioning block 73 towards the baffle 3, thereby allowing the insertion part 732 to engage in the slot 712. After the operation is completed, the paddle 733 returns to its original position against the sliding part 731, preventing the outwardly extending paddle 733 from pressing against the patient's oral cavity, thus improving the comfort of using the mouthpiece.
[0033] It's important to understand that since the mouthpiece is a disposable medical device, generally, once the length of the telescopic rod 7 is adjusted according to the patient's mouth size, no further adjustment is needed. Therefore, the setting of the limiting strip 734 and the lever 733 to abut against each other facilitates the insertion of the positioning block 73 into the slot 712, while also allowing the positioning block 73 to be folded and stored. However, in the event of misoperation, if a secondary adjustment of the telescopic rod 7 is required, the position of the lever 733 can be stabilized using two fingers, or a tool can be used to press against the limiting strip 734 to push the positioning block 73 towards the guide groove 711.
[0034] In a preferred embodiment, see [reference] Figure 4 The baffle 3 is provided with two vertical grooves 31, and the lower piece 6 is provided with two sliders 61 that are slidably connected to the two vertical grooves 31 respectively. During adjustment, the lower piece 6 slides in the vertical direction to further improve the stability of the installation of the lower piece 6.
[0035] In a preferred embodiment, see [reference] Figure 1 , 2 3. The baffle 3 has a first strap hole 32 on one side and two parallel second strap holes 33 on the other side. One end of the elastic band 4 is connected to the first strap hole 32, and the other end is wrapped around the two second strap holes 33. The surface of the elastic band 4 is provided with several anti-slip strips 41. Different anti-slip strips 41 are inserted into the second strap holes 33, which can adjust the installation length of the elastic band 4 so as to fix the bite body 1 on different head circumferences and meet the needs of people of different ages.
[0036] In a preferred embodiment, see [reference] Figure 3 The bottom of the lower piece 6 is provided with two symmetrically arranged L-shaped clips 62. The tongue depressor 2 is slidably connected to the two L-shaped clips 62. By adjusting the position of the tongue depressor 2 on the lower piece 6, the length of the tongue depressor 2 extending into the patient's mouth can be controlled to avoid the tongue depressor 2 being too long and coming into contact with the base of the patient's tongue, which could easily cause a feeling of gagging, or to avoid the tongue depressor 2 being too short and unable to press down on the patient's tongue, thus failing to open the airway.
[0037] Further, see Figure 3 The lower piece 6 has a protruding strip 63 at its bottom, and the tongue depressor 2 has several transverse grooves 21 arranged along its length. The protruding strip 63 can be inserted into any of the transverse grooves 21 to fix the position of the tongue depressor 2. Pushing the tongue depressor 2 allows the protruding strip 63 to be inserted into any of the transverse grooves 21, so as to adjust the position of the tongue depressor 2.
[0038] Preferably, to improve the comfort of using the mouthpiece, the edges of the upper piece 5, the lower piece 6, and the tongue depressor 2 are all rounded.
[0039] In a preferred embodiment, see [reference] Figure 1 , 2 It also includes a silicone pad 8, which is located on the side of the baffle 3 near the bite body 1. During actual examinations, the endoscope tube rests on the baffle 3 due to its own weight, which increases the pressure of the baffle 3 on the patient's mouth, making the patient's mouth prone to redness. Therefore, by setting the silicone pad 8, the comfort of the contact between the baffle 3 and the patient's mouth can be improved.
[0040] See Figure 3 The silicone pad 8 has a retaining edge 81 that wraps around the edge of the baffle 3, allowing for a detachable connection between the silicone pad 8 and the baffle 3, and ensuring high installation stability. In practical use, replacing different silicone pads 8 helps to adapt to bite bodies 1 of different diameters, thus bridging the gap between the lower piece 6 and the baffle 3.
[0041] In summary, this invention achieves height adjustment of the telescopic rod 7 through the cooperation of the adjusting rod 71, the sleeve rod 72, and the positioning block 73, making the diameter of the mouthpiece 1 adjustable. It also features an adjustable tongue depressor 2, making it suitable for patients with different oral cavity sizes and meeting the needs of various users. Furthermore, the baffle 3 is equipped with a silicone pad 8, which improves the comfort of using the mouthpiece.
[0042] It is understood that those skilled in the art can make equivalent substitutions or changes based on the technical solution and inventive concept of this utility model, and all such substitutions or changes should fall within the protection scope of the appended claims of this utility model.
