[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Next, the working principle of this embodiment is described in detail to enable those skilled in the art to better understand the present invention:

[0023] refer to Figure 1 A combined mouth ring for gastroscopy includes a mouth ring body 1, an inner soft rubber sleeve 2, and an outer soft rubber sleeve 3. The inner soft rubber sleeve 2 is mounted on the inner side wall of the mouth ring body 1, and the outer soft rubber sleeve 3 is mounted on the occlusal surface of the mouth ring body 1. The outer soft rubber sleeve 3 and the inner soft rubber sleeve 2 are generally made of rubber. The outer soft rubber sleeve 3 is used to protect the patient's teeth, and the inner soft rubber sleeve 2 is used to protect the gastroscope.

[0024] refer to Figure 2 and Figure 3The mouth ring body 1 includes a fixed baffle 4, an oral septum 5, a connecting plate 6, a first conduit channel 7, and a second conduit channel 8. One end of the first conduit channel 7 is connected to the fixed baffle 4, which is used to position the mouth ring body 1 outside the oral cavity and prevent it from completely entering the oral cavity. One end of the second conduit channel 8 is connected to the oral septum 5, which is used to prevent oral tissue from interfering with the gastroscope. The other end of the first conduit channel 7 is provided with a mounting groove 10, and the other end of the second conduit channel 8 is mounted with a connecting plate 6 corresponding to the mounting groove 10. The outer surfaces of the first and second conduit channels 7 and 8 are occlusal surfaces. The connection between the first and second conduit channels 7 and 8 is achieved by the engagement of the connecting plate 6 and the mounting groove 10. Conversely, the connection is achieved by the separation of the first and second conduit channels 7 and 8. The connecting plate 6 and the mounting groove 10 form an interference fit. When the patient needs to install the outer soft rubber sleeve 3 on the occlusal surface, or the doctor needs to install the inner soft rubber sleeve 2 in the first and second catheter channels 7 and 8, the first and second catheter channels 7 and 8 can be separated, and then the inner and outer soft rubber sleeves 2 and 3 are placed on the inner and outer walls of the first catheter channel 7, and finally the first and second catheter channels 7 and 8 are connected. The inner and outer soft rubber sleeves 2 and 3 can prevent the patient's teeth or gastroscope from directly contacting the first and second catheter channels 7 and 8 and being damaged. In cases where the inner and outer soft rubber sleeves 2 and 3 are not needed, the mouth ring body 1 of the present invention can be used directly, reducing costs.

[0025] A limiting groove 9 is provided on the outer wall of the second conduit passage 8, which is connected to a mounting groove 10. A positioning block 11 is mounted on the connecting plate 6, and the positioning block 11 slides in cooperation with the limiting groove 9. The limiting groove 9 includes a radial portion 901 and an axial portion 902. The radial portion 901 and the axial portion 902 are perpendicular and interconnected. When the positioning block 11 slides to the end of the radial portion 901 away from the axial portion 902, the first conduit passage 7 and the second conduit passage 8 are fixedly connected. To further improve the reliability of the connection between the first and second conduit passages 7 and 8 and avoid problems during inspection, the positioning block 11 and the limiting groove 9 can be used for auxiliary fixation. When the connecting plate 6 enters the mounting groove 10, the positioning block 11 needs to correspond to the axial portion 902 so that the positioning block 11 slides into the axial portion 902. When the connecting plate 6 completely enters the mounting groove 10, the positioning block 11 moves to the connection between the axial portion 902 and the radial portion 901. At this time, the second conduit channel 8 is rotated to allow the positioning block 11 to slide into the radial portion 901. The radial portion 901 and the positioning block 11 cooperate to limit the axial displacement of the second conduit channel 8.

[0026] refer to Figure 4A limiting protrusion 12 is provided at one end of the radial portion 901 away from the axial portion 902. The limiting protrusion 12 makes the width of the limiting groove 9 smaller than the diameter of the positioning block 11. The limiting protrusion 12 can limit the positioning block 11 from rotating freely along the radial portion 901, thereby locking the positioning block 11.

[0027] A positioning groove 13 is provided on the side of the fixed baffle 4 away from the first catheter channel 7. A fixing block 14 is installed symmetrically about the axis of the first catheter channel 7 in the positioning groove 13. The inner soft rubber sleeve 2 includes a positioning portion 201 and a protective portion 202. The positioning portion 201 is provided with a positioning hole corresponding to the fixing block 14. The length of the protective portion 202 is equal to the sum of the lengths of the first catheter channel 7 and the second catheter channel 8, so that the gastroscope connecting rod will not come into contact with the first catheter channel 7 and the second catheter channel 8. To prevent the inner soft rubber sleeve 2 from being displaced during contact with the gastroscope connecting rod, the positioning groove 13 and the positioning hole cooperate to allow the positioning portion 201 to be snapped onto the fixing block 14, restricting the inner soft rubber sleeve 2 from moving in the direction of entering the oral cavity.

[0028] A drainage port is provided on the oral partition 5 , and one end of a drainage tube is connected to the drainage port. The drainage tube is used to drain the liquid in the oral cavity to prevent the saliva produced in the oral cavity from affecting the gastroscopy examination.
