[0030] Example

[0031] Please refer to Figures 1-7. This utility model provides an oral tongue depressor and saliva suction device, including a tongue depressor 1 and a saliva suction tube 2. A limiting ring 3 is fitted around the outside of the saliva suction tube 2. The limiting ring 3 is connected to one end of a rotating component 5. The other end of the rotating component 5 is connected to a rotating assembly 6, which is connected to the tongue depressor 1. The tongue depressor 1 includes a handle 11, a bent section 12, a transition section 13, and a replacement section 14 connected in sequence. The replacement section 14 and the transition section 13 are connected by a snap-fit ​​component. The bent section 12 is inclined and has an arc. Anti-slip pads 111 are fixedly connected to both the upper and lower surfaces of the handle 11 to facilitate the grip of medical personnel on the tongue depressor 1.

[0032] The snap-fit ​​assembly includes two snap-fit ​​plates 41 and one snap-fit ​​connector 42. The snap-fit ​​connector 42 is fixedly connected to the snap-fit ​​block 43, which is fixedly located at the end of the replacement section 14. A cavity 131 is formed at the end of the transition section 13, and a connecting plate 44 is disposed within the cavity 131. A connecting groove is formed on the connecting plate 44, and side wings 45 are provided on both sides of the connecting groove. A pin 46 passes through the connection point of the two snap-fit ​​plates 41, and both ends of the pin 46 are connected to the side wings 45. Compression springs 47 are provided on both sides of the connecting plate 44, and the top ends of the compression springs 47 are fixedly connected to the side ends of the snap-fit ​​plates 41.

[0033] When in use, insert the snap-fit ​​connector 42 on the replacement section 14 between the two snap-fit ​​plates 41 in the cavity of the transition section 13. The snap-fit ​​plates 41 on both sides are pressed together by the extension force provided by the compression springs 47 on both sides, so that they clamp the snap-fit ​​connector 42. When it is necessary to replace the disposable replacement section 14, use tweezers to hold the replacement section 14 and pull it off, so that the snap-fit ​​connector 42 can be released from the snap-fit ​​plate 41. Repeat the above process when replacing a new replacement section 14.

[0034] The rotating assembly 5 includes a rotating shaft 51 with one end connected to a limiting ring, and the other end of the rotating shaft 51 rotatably connected to the bottom of a cylindrical tube 53 via a bearing 52. The cylindrical tube 53 has an internal cavity containing a circular plate 54. A through hole is located at the center of the circular plate 54, through which the rotating shaft 51 passes, and a bearing 55 is provided at the connection point. The circular plate 54 improves the stability of the rotating shaft 51's rotation.

[0035] The rotating assembly 6 includes a rotating block 61 connected to the bottom of the cylindrical tube 53. The rotating block 61 and the fixed clamping block 62 are rotatably connected via a rotating shaft 63. The fixed clamping block 62 is fixedly connected to the insertion block 64, and the insertion block 64 is inserted into the transition section 13. As shown in Figure 7, the insertion block 64 is provided with an insertion rod 641, and the transition section 13 is provided with an insertion hole 132. When only the tongue depressor 1 is used, the rotating assembly 5 and the rotating assembly 6 can be removed for convenient use and cleaning.

[0036] By setting the rotating component 5, the saliva suction tube 2 can make a circular motion within the limiting ring 3. The rotating component also allows the saliva suction tube 2 to move left and right. Furthermore, the inner diameter of the limiting ring 3 is slightly larger than the outer diameter of the saliva suction tube 2, allowing the saliva suction tube 2 to freely adjust its depth into the oral cavity and its working position within the oral cavity, thus improving its flexibility of use.

[0037] One end of the saliva suction tube 2 is fitted with a saliva suction head 21. The saliva suction head 21 is a disposable structure that is fitted onto the saliva suction tube 2 for easy replacement and to avoid cross-infection. The other end of the saliva suction tube 2 is connected to a negative pressure device, which is existing technology in the field and is used for saliva suction operations of the saliva suction tube 2. It will not be described in detail here.

[0038] A fixing ring 22 is also fixedly fitted onto the saliva suction tube 2. A connecting post 23 is provided on the fixing ring 22. A connecting port is provided on the limiting ring 3. The connecting port and the connecting post 23 are compatible. When not in use, the limiting ring 3 and the fixing ring 22 can be aligned and the connecting post 23 can be inserted into the connecting port to prevent the saliva suction tube 2 from moving and falling off.

[0039] The lower part of the suction tube 2 is connected to a waste liquid outlet 24. A filter screen 25 is installed inside the lumen of the suction tube 2. The filter screen 25 is inclined and positioned above the waste liquid outlet 24. The filter screen 25 intercepts blood vessels or other fine fabric particles during the suction process and discharges them through the waste liquid outlet 24, preventing them from being sucked into the negative pressure device and affecting its use. The waste liquid outlet 24 is connected to a waste liquid pipe 26 for easy disassembly. The other end of the waste liquid pipe 26 is connected to a waste liquid treatment tank (not shown in the figure).

[0040] The inner diameter of the limiting ring 3 is larger than the outer diameter of the saliva suction tube 2. This design allows the saliva suction tube 2 to move back and forth within the limiting ring 3, facilitating the adjustment of the working position of the saliva suction tube 2. The outer diameter of the limiting ring 3 is the same as the outer diameter of the fixing ring 22, which facilitates the connection between the connection port and the connecting post 23.

[0041] In practical use, a brand-new disposable replacement section 14 is installed at the end of the transition section 13, and a brand-new saliva suction head 21 is installed at one end of the saliva suction tube 2. The other end of the saliva suction tube 2 is connected to the negative pressure device. Medical staff operate by holding the handle 11, grasping the end of the saliva suction tube 2 that is close to the negative pressure device, and adjusting the saliva suction position until it is completed.

[0042] Therefore, this utility model adopts the above-mentioned oral tongue depressor and saliva suction device. By setting a tongue depressor with a bent section, it avoids obstructing the view and improves applicability. By setting a replaceable disposable section, it avoids cross-infection. By combining the tongue depressor with the saliva suction tube, the tongue depressor can be used to press down the tongue while the saliva suction tube can be used to remove saliva, blood or rinsing fluid in the mouth in time. This reduces the need to frequently change tools or pause the operation due to saliva or other liquids obstructing the view, making the examination or treatment process smoother.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of this utility model.
