[0035] The following will be combined with the attached Figure 2 To the attached Figure 5 And specific embodiments will be used to elaborate on the present invention in detail:

[0036] As Figure 2-5 shown, the present invention provides a dental pad, which includes:

[0037] A bite body 1, the bite body 1 includes a rotating part 10 and a biting part 11. The cross-section of the free end of the biting part 11 (i.e., the end for extending into the patient's mouth) forms a rectangle, the rectangle has a long side 12 and a short side 13, and a through hole 14 is provided in the middle of the bite body 1 for sputum suction, etc.; preferably, a soft rubber sleeve 8 can be sleeved on the bite body 1, and the soft rubber sleeve 8 can effectively protect the patient's teeth and prevent the patient's teeth from directly contacting the harder bite body 1;

[0038] An extending body 2, the extending body 2 is sleeved on the rotating part 10 of the bite body 1 and is rotatably connected to the bite body 1.

[0039] Specifically, a blocking piece 3 and a locking sleeve 4 are sleeved on the free end of the rotating part 10 of the bite body 1. The blocking piece 3 is locked by the locking sleeve 4, and the locking sleeve 4 locks and fixes the blocking piece 3 on the bite body 1. There are various ways to fix the blocking piece 3. For example, the locking sleeve 4 and the bite body 1 can be tightly fitted to realize the pressing and fixing of the blocking piece 3; it can also be that the blocking piece 3 is a ring structure, correspondingly sleeved on the bite body 1, the locking sleeve 4 is sleeved on the free end of the rotating part 10 of the bite body 1, is threadedly connected to the rotating part 10, and presses against the blocking piece 3 to realize the locking and fixing of the blocking piece 3.

[0040] At the same time, a reset elastic member 5 is provided between the extending body 2 and the bite body 1. One end of the reset elastic member 5 is connected to the blocking piece 3, and the other end is connected to the extending body 2 to realize the rotational connection between the extending body 2 and the bite body 1. Multiple groups of the reset elastic members 5 can be provided, and the reset elastic members 5 can make the rotating part 10 of the bite body 1 close to the extending body 2 to realize the reset after the bite body 1 rotates.

[0041] In the dental pad of the present utility model, when in normal use, the patient can directly bite on the short side 13 of the occlusal part 11. When the opening and closing degree of the patient's mouth is small, the medical staff can rotate the occlusal body 1 by 90 degrees so that the long side 12 faces the patient's teeth. Since the length of the long side 12 is greater than that of the short side 13, the patient can use the dental pad for assistance without opening the mouth too wide. On the basis of the dental pad in the prior art, the present utility model separates the occlusal body 1 from the protruding body 2, and adjusts the thickness at the occlusal position of the patient by rotating the occlusal body 1 to adapt to the patient's mouth.

[0042] Specifically, the protruding body 2 includes a protruding part 20 and a stopping part 21; among them,

[0043] The protruding part 20 is in a hollow ring shape and is sleeved on the occlusal body 1;

[0044] The stopping part 21 is in a plate shape and has a certain thickness, which is used to fit the human lips and stop on the outer end face 15 at the connection between the occlusal part 11 and the rotating part 10. A U-shaped insertion groove 211 is opened in the stopping part 21, and a limiting flap 6 is installed in the U-shaped insertion groove 211, and the limiting flap 6 can block the U-shaped insertion groove 211. Connection holes 212 for connecting earplugs can also be provided on both sides of the stopping part 21 of the protruding body 2.

[0045] The limiting flap 6 is in an L shape, and the L-shaped limiting flap has a vertical side and a horizontal side. A protruding part 60 is formed on the vertical side, and the protruding part 60 can block the U-shaped insertion groove 211.

[0046] In this embodiment, two U-shaped insertion grooves 211 are provided, which are respectively arranged on both sides of the protruding part 20 of the protruding body 2, and the opening directions of the two U-shaped insertion grooves 211 are opposite.

[0047] During the use process, when it is necessary to place an indwelling catheter, the medical staff directly puts the indwelling catheter into the opening of the U-shaped insertion groove 211. During the putting-in process, the protruding part 60 of the limiting flap 6 will be deformed by the extrusion of the indwelling catheter. When the indwelling catheter is placed at the bottom of the U-shaped insertion groove 211, the limiting flap 6 that loses the restriction resets, so that the protruding part 60 blocks the opening of the U-shaped insertion groove 211, and preliminarily restricts the indwelling catheter to prevent the indwelling catheter from directly sliding out of the U-shaped insertion groove 211; it can be seen that the limiting flap 6 can assist in fixing the catheter and prevent the indwelling catheter from falling off during the treatment process.

[0048] Specifically, the dental pad further includes an auxiliary clamp sleeve 7.

[0049] Auxiliary plug holes 22 are provided on both sides of the extension part 20 of the extension body 2, and the auxiliary jacket 7 is installed in the auxiliary plug holes 22. In this embodiment, the auxiliary jacket 7 is plugged and installed in the auxiliary plug holes 22, and the installation method is simple and convenient.

[0050] After the initial restriction of the indwelling catheter is completed, the indwelling catheter only needs to be pressed against the extension portion 20 of the extension body 2 and the auxiliary jacket 7 is used to assist in locking the indwelling catheter to prevent the indwelling catheter from falling off during the treatment process.

[0051] Specifically, the outer end surface 15 where the occlusal portion 11 and the rotating portion 10 are connected is provided with a plurality of first concave-convex cambered surfaces 151; the abutting surface 213 of the stop portion 21 and the occlusal body 1 is provided with a plurality of second concave-convex cambered surfaces 2131, the first concave-convex cambered surfaces are adapted to the second concave-convex cambered surfaces, the concave-convex cambered surfaces of the occlusal body 1 and the protruding body 2 are fitted to each other, and at the same time, it is ensured that the first concave-convex cambered surface on the occlusal body 1 and the second concave-convex cambered surface on the protruding body 2 can still fit to each other after each 90-degree rotation. When the occlusal body 1 is rotated, the concave-convex cambered surfaces of the occlusal body 1 and the protruding body 2 are staggered. Since the concave-convex cambered surfaces have a certain thickness, the occlusal body 1 will move a short distance backwards during rotation. At this time, the blocking sheet 3 compresses the reset elastic member 5, and the concave-convex cambered surfaces of the occlusal body 1 and the protruding body 2 fit again after 90-degree rotation, and under the action of the reset elastic member 5, the occlusal body 1 is again close to the protruding body 2. In this embodiment, the cross-sectional shape of the rotating part 11 is circular. Correspondingly, four groups of the first concave-convex arc surface on the outer end surface 15 and the second concave-convex arc surface on the abutting surface 213 are arranged, forming an array around the center of the rotating part 11, similar to a four-blade windmill structure.

[0052] The utility model is further described above with the help of specific embodiments, but it should be understood that the specific description here should not be construed as limiting the essence and scope of the utility model. Various modifications made to the above embodiments by ordinary technicians in this field after reading this specification are all within the scope of protection of the utility model.
