Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary equipment technology, specifically to a tongue-blocking saliva suction device. Background Technology

[0002] In most clinical dental procedures, high-speed vortex handpieces are used. Due to their high speed, reaching hundreds of thousands of revolutions per minute, and the multi-pore spray at the end face, especially in children whose tongues move involuntarily during treatment, the bur can cause damage, bleeding, and pain if it scratches the tongue. Therefore, the protection of the tongue and soft tissues is particularly important in dental procedures.

[0003] However, while existing tongue-blocking saliva suction devices can protect the patient's mouth during use, tartar can form during oral cavity treatment. When tartar fragments are generated, they cannot be suctioned out of the suction channel of the saliva suction device, which can easily clog the pipes and affect the suction effect. Therefore, we have proposed a tongue-blocking saliva suction device. Utility Model Content

[0004] The purpose of this invention is to provide a tongue-blocking saliva suction device to address the aforementioned shortcomings in the technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tongue-blocking saliva suction device, comprising a silicone support block, an air suction hole at the center of the outer wall of one end of the silicone support block, a silicone tongue-blocking plate fixedly provided on one side of the outer wall of the silicone support block, liquid suction holes evenly distributed on the bottom side of the outer wall of the silicone tongue-blocking plate, a silicone frame fixedly provided on the bottom side of the outer wall of the silicone tongue-blocking plate, a metal filter screen installed on the inner wall of the silicone frame, and one end of the liquid suction hole located inside the silicone frame.

[0006] Preferably, the silicone support block has positioning grooves on its top and bottom outer walls. These positioning grooves facilitate the patient's teeth from biting together, prevent the silicone support block from falling out of the patient's mouth, and make it easier for the silicone support block to expand the patient's mouth.

[0007] Preferably, an air suction tube is inserted into the inner wall of one end of the air suction hole, and a pipe connector is fixedly provided on the outer wall of one end of the air suction tube, so that the air suction tube can be easily connected to the negative pressure air suction device through the pipe connector.

[0008] Preferably, one side of the outer wall of the silicone support block has equally spaced liquid guiding holes, and the two ends of the liquid guiding holes are respectively connected to the liquid suction hole and the air suction hole.

[0009] Preferably, the mesh radius of the metal filter is smaller than the radius of the liquid absorption hole to prevent fragments that cannot pass through from entering the liquid absorption hole.

[0010] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0011] A silicone frame is fixed to one side of the outer wall of the silicone tongue guard. A metal filter screen is provided on the inner wall of the silicone frame to block the outside of the suction end of the suction hole. This can filter the suctioned saliva, prevent tartar from entering the suction hole, prevent blockage, and improve the suction effect of the patient's mouth. Attached Figure Description

[0021] Example 1

[0022] Refer to the instruction manual appendix Figure 1-4 A tongue-blocking saliva suction device includes a silicone support block 1. An air suction hole 3 is opened at the center of the outer wall of one end of the silicone support block 1. A silicone tongue-blocking plate 4 is fixedly provided on one side of the outer wall of the silicone support block 1. Liquid suction holes 5 are evenly distributed on the bottom side of the outer wall of the silicone tongue-blocking plate 4. A silicone frame 7 is fixedly provided on the bottom side of the outer wall of the silicone tongue-blocking plate 4. A metal filter screen 8 is installed on the inner wall of the silicone frame 7. One end of the liquid suction hole 5 is located inside the silicone frame 7.

[0023] Example 2

[0024] Based on Embodiment 1, the top and bottom outer walls of the silicone support block 1 are provided with positioning grooves 2. The positioning grooves 2 facilitate the patient's teeth to bite down and prevent the silicone support block 1 from falling out of the patient's mouth. The silicone support block 1 facilitates the expansion of the patient's mouth. An air inlet 9 is inserted into the inner wall of one end of the air inlet 3. A pipe connector 10 is fixedly provided on the outer wall of one end of the air inlet 9. The pipe connector 10 facilitates the connection of the air inlet 9 to the negative pressure air inlet device.

[0025] Example 3

[0026] Based on Embodiment 1, one side of the outer wall of the silicone support block 1 has equally spaced liquid guiding holes 6. The two ends of the liquid guiding holes 6 are connected to the liquid suction hole 5 and the air suction hole 3, respectively. The mesh radius of the metal filter screen 8 is smaller than the hole radius of the liquid suction hole 5 to prevent fragments that cannot pass through from entering the liquid suction hole 5.

[0027] Working principle of this utility model:

[0028] Refer to the instruction manual appendix Figure 1-4In use, the silicone support block 1 is placed in the patient's mouth, with the support block 1 positioned away from the treatment area. The patient's teeth bite into the positioning grooves 2 at the top and bottom of the silicone support block 1, providing support for the patient's mouth. Then, the silicone tongue guard 4 is placed on the patient's tongue, and the suction tube 9 is connected to the negative pressure device through the pipe connector 10. This allows the liquid in the patient's mouth to be drawn into the suction hole 3 through the suction hole 5 and the guide hole 6. The liquid in the suction hole 3 is then drawn out through the suction tube 9, effectively removing cleaning fluid, saliva, and blood from the patient's mouth. During the saliva suction process, the silicone frame 7 fixed to one side of the outer wall of the silicone tongue guard 4, and the metal filter 8 on the inner wall of the silicone frame 7, block the suction end of the suction hole 5, filtering the saliva and preventing tartar buildup from entering the suction hole 5. This prevents blockage and improves the suction effect on the patient's mouth.

[0029] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
