Description

Technical Field

[0001] The utility model relates to the technical field of medical care, and more specifically, to a tongue-biting-proof teeth opener. Background Art

[0002] Since epileptic patients will experience paroxysmal mental disorders, they are prone to muscle tension disorders throughout the body. If the throat muscles are involved, the patient's teeth may be clenched easily, causing the patient to bite his tongue. In the daily care of epileptic patients, anti-tongue biting teeth openers are often used.

[0003] At present, the tongue-biting prevention devices used by epilepsy patients in hospitals are generally rod-shaped structures, which generally involve inserting a rod with a certain width between the upper and lower teeth of the epilepsy patient. Although this tongue-biting prevention device can prevent the tongue from biting, it cannot adjust the angle of the oral opening, which can easily cause discomfort to the patient's facial muscles. In addition, this tongue-biting prevention device has a single function and poor practicality. Therefore, in view of the above problems, an tongue-biting prevention teeth opener is proposed. Utility Model Content

[0004] (1) Technical issues to be solved

[0005] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a tongue-biting-proof teeth opener, which has an adjustment function to facilitate medical staff to adjust the angle of the patient's oral opening.

[0006] (2) Technical solution

[0007] The top end of the adjusting board is provided with a rotating shaft, and the second end of the rotating shaft is provided with a rotating shaft, and the second end of the rotating shaft is rotatably connected to the first threaded rod and the second threaded rod. The first threaded rod and the second threaded rod are rotatably connected to the bearing fixedly connected to the bottom end of the adjusting board. The surfaces of the first threaded rod and the second threaded rod are threadedly connected to the threaded caps, and the surfaces of the two sliding blocks and the two threaded caps are fixedly connected to the movable plate, one end of the two movable plates slides through the movable groove, and is fixedly connected to the arc connecting rod, and the side surface of the arc connecting rod is fixedly connected to the bite block.

[0008] When using an anti-tongue biting teeth opener of the present technical solution, a knob is set. When people need to adjust the angle of the patient's oral opening, they rotate the knob to rotate the rotating shaft, the first threaded rod and the second threaded rod, which can drive the two movable plates to move on the surfaces of the first threaded rod and the second threaded rod, and adjust the distance between the two arc-shaped connecting rods, thereby making it easier for people to adjust the angle of the patient's oral opening.

[0009] Furthermore, one end of one of the straps is fixedly connected to a fixing ring, and one end of the other strap is fixedly connected to a Velcro tape.

[0010] Furthermore, a Velcro tape is fixedly connected to the surface of one of the straps.

[0011] Furthermore, air-permeable layers are provided on the inner sides of the two straps.

[0012] Furthermore, tooth grooves are formed on the side surfaces of the bite block.

[0013] Furthermore, a rubber strip is fixedly connected to the inner side surface of the tooth groove.

[0014] (3) Beneficial effects

[0015] In summary, the utility model has the following beneficial effects:

[0016] 1. This anti-bite tongue opener is provided with a knob. When people need to adjust the angle of the patient's oral opening, they rotate the knob to rotate the shaft, the first threaded rod and the second threaded rod, which can drive the two movable plates to move on the surfaces of the first threaded rod and the second threaded rod, and adjust the distance between the two arc-shaped connecting rods, so that people can adjust the angle of the patient's oral opening.

[0017] 2. This anti-tongue biting teeth opener is provided with straps. Medical staff wrap the two straps around the patient's head, and then pass the Velcro through the fixing ring and stick it to the Velcro mother tape to connect the two straps, so that it is convenient for medical staff to fix the device on the patient's face. At the same time, under the action of the breathable layer, the air permeability between the straps and the patient's face can be enhanced. BRIEF DESCRIPTION OF THE DRAWINGS
