Description

Technical Field

[0001] The utility model relates to the technical field related to anti-swallowing, in particular to an oral anti-swallowing device. Background Art

[0002] During the oral and dental examination and correction surgery, the opening device plays an important role. It can assist the doctor in fixing the patient's lips and opening the mouth, making it easier for the doctor to perform the surgery. During the current surgery, the patient needs to keep his tongue in the correct position at all times to avoid affecting the doctor's surgery due to improper tongue placement. Moreover, during the surgery, the patient's salivary glands will continue to secrete, causing the patient to swallow all the time. The patient's swallowing action will affect the progress of the surgery, so the patient's mouth needs to be opened and fixed to avoid swallowing.

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Reference Figure 1-3 The oral anti-swallowing device shown comprises:

[0020] The upper and lower abutment blocks 1 and 2 are used to support the upper and lower jaws respectively. In order to better fit the shape of the upper jaw and limit the tongue at the same time, the upper end surface of the upper abutment block 1 is set to an arc shape, and the lower abutment block 2 is set to a semi-elliptical shape corresponding to the tongue, and the lower end surface of the lower abutment block 2 is provided with a depression. The edge of the lower abutment block 2 abuts against the lower jaw, and also limits the position of the tongue to avoid the influence of the tongue;

[0021] Specifically, a U-shaped connecting piece 3 is provided between the upper resisting block 1 and the lower resisting block 2, and the two ends of the U-shaped connecting piece 3 are fixedly connected to the upper resisting block 1 and the lower resisting block 2 respectively. An adjustable supporting assembly is provided between the upper resisting block 1 and the lower resisting block 2, and the distance between the upper resisting block 1 and the lower resisting block 2 can be adjusted, so as to limit the size of the opening of the oral cavity. Specifically, the adjustable supporting assembly includes a fixing rod 6 vertically fixedly provided on the lower resisting block 2, and a circular hole groove is provided at the upper end of the fixing rod 6, and a screw member 7 is slidably provided in the circular hole groove. A rotating block 8 is threadedly sleeved on the screw member 7, and the rotating block 8 is rotatably connected to the fixing rod 6. Due to the limiting effect of the U-shaped connecting piece 3, the rotating rotating block 8 can control the vertical movement of the screw member 7 through the threaded structure, thereby controlling the length of the adjustable supporting assembly, and then realizing the change of the opening height;

[0022] After the mouth is stretched open, the lips will still block the outside of the teeth to a certain extent. Therefore, two openers 4 are symmetrically arranged on the front sides of the upper and lower blocks 1 and 2. The two openers 4 are arranged in a U-shape and the cross-sections of the two openers 4 are arranged in an arc shape. The two openers 4 are fixedly connected to the U-shaped connecting piece 3 through an arc-shaped connecting strip 5. Compared with the existing openers 4, the size of the opener 4 is larger, and the lips can be stretched open when the mouth is open. The opener 4 and the arc-shaped connecting strip 5 can be connected by a snap-fit ​​structure to achieve the detachability of the opener 4 and ensure the overall applicability.

[0023] In order to increase the overall comfort of use, the upper block 1, the lower block 2, the U-shaped connector 3, the opener 4 and the arc-shaped connecting strip 5 are all made of medical plastic materials, and the surfaces of the upper block 1, the lower block 2 and the opener 4 are all provided with a soft rubber layer; at the same time, the U-shaped connector 3 and the arc-shaped connecting strip 5 are both provided with elasticity, and the elasticity of the U-shaped connector 3 adapts to the change in the length of the adjustable support component, and the elasticity of the arc-shaped connecting strip 5 allows the position of the opener 4 to be changed. In order to maintain rigidity, the edges at both ends of the arc-shaped connecting strip 5 are spliced ​​with rigid materials to provide support.

[0024] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
