Description

Technical Field

[0001] The utility model relates to the technical field of oral support, in particular to an oral support device. Background Art

[0002] Stomatology is one of the classifications of medical disciplines. The main oral diseases include: oral and maxillofacial dermoids, epidermal submandibular space infection, maxillofacial lymphangioma, odontoid malformation, maxillary sinus malignant tumor, jaw ameloblastoma, chronic ethmoid sinusitis, mandibular retrusion, tetracycline teeth, leukoplakia of the tongue and other diseases. With current technology, many periodontal diseases can be completely cured. During the oral treatment, patients are sometimes required to keep their mouths open for a long time, and equipment is needed to support the patient's mouth.

[0003] An existing oral support device (authorization announcement number CN215130689U) has the following defects: the above-mentioned device supports the patient's mouth through a support plate, and the screw rod rotates to control the first connecting rod and the second connecting rod, thereby controlling the lifting and lowering of the two support plates. The two connecting rods are rotatably connected to the support plates through a fixed block. When supporting the patient's mouth, the upper support plate is tilted due to the effect of the oral angle during occlusion, resulting in uneven force between the two connecting rods. Due to the rotatable connection between the connecting rod and the support plate, when subjected to external force, the device is prone to shaking and has poor stability, resulting in poor support effect. Utility Model Content

[0004] The utility model aims to solve the problems existing in the prior art and provides an oral support device.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Please see attached Figure 1 -Attached Figure 5 An oral support device comprises a mounting plate 1, the mounting plate 1 is made of rubber, an upper support plate 2 is rotatably provided on one side of the mounting plate 1, a lower support plate 3 is fixed on one side of the mounting plate 1, a support structure is provided between the upper support plate 2 and the lower support plate 3, the support structure comprises a fixed block 201 fixed on the top surface of the lower support plate 3, a screw rod 202 is rotatably provided on one side of the fixed block 201, a support block 203 is fixed on the top surface of the lower support plate 3, the support block 203 and the screw rod 202 are rotatably provided, a movable plate 204 is hinged on the bottom surface of the upper support plate 2, a notch is provided on the bottom surface of the movable plate 204, a movable plate 205 is rotatably provided on the notch on the bottom surface of the movable plate 204, a threaded hole is provided on one side of the movable plate 205, and the threaded hole on one side of the movable plate 205 is threadedly connected to the screw rod 202.

[0023] In the embodiment, the bottom surface of the movable plate 204 is hinged with a transmission plate 206, and the top surface of the transmission plate 206 is hinged with a stabilizing plate 207. The top surface of the stabilizing plate 207 is hinged to the bottom surface of the upper support plate 2, and a movable notch 208 is opened on one side of the stabilizing plate 207. The screw rod 202 is rotatably arranged with the movable notch 208, and the stabilizing plate 207 is parallel to the movable plate 204. Through the setting of the supporting structure, the screw rod 202 drives the movable plate 205 to move backward, and the movable plate 204 moves with the movable plate 205. During the movement, the inclination angle of the movable plate 204 increases and lifts up the upper support plate 2 to support the patient's oral cavity. At the same time, under the action of the transmission plate 206, the movable plate 204 makes the inclination angle of the stabilizing plate 207 change with the change of the movable plate 204, so that the stabilizing plate 207 assists in supporting the upper support plate 2, thereby improving the stability of the equipment, making it less likely to shake during the support process, and the equipment is small in size and only supports one side of the patient's oral cavity, occupies a small space, and is convenient for medical staff to operate.

[0024] In the embodiment, a through slot 301 is opened on one side of the lower support plate 3, a rotating shaft 302 is fixed inside the through slot 301, a tongue depressor 303 is arranged inside the through slot 301, and the tongue depressor 303 is rotatably arranged with the rotating shaft 302. The medical staff can rotate the tongue depressor 303 out of the through slot 301 to press the patient's tongue to prevent the patient's tongue from moving around in the oral cavity, making the operation of the medical staff more convenient.

[0025] In the embodiment, a connecting arc plate 4 is provided on one side of the mounting plate 1. The connecting arc plate 4 is made of rubber. Both sides of the connecting arc plate 4 are respectively fixed to the upper support plate 2 and the lower support plate 3. The connecting arc plate 4 is made of polyethylene and has good elasticity and durability. The upper support plate 2 and the lower support plate 3 are connected to provide certain support therefor, thereby reducing the pressure on the movable plate 204.

[0026] In the embodiment, the top surface of the upper support plate 2 and the bottom surface of the lower support plate 3 are both fixed with anti-dropout plates 5, which are made of rubber. The anti-dropout plates 5 can fit the inner sides of the teeth in the patient's mouth to prevent the device from falling off the patient's mouth. The top surface of the upper support plate 2 and the bottom surface of the lower support plate 3 are both fixed with protective layers 6, which are made of rubber cotton. During the support process, the patient's teeth are protected to improve the patient's comfort.

[0027] Working principle: During use, the medical staff puts the device into one side of the patient's oral cavity so that the device is located between the patient's upper and lower teeth, and the mounting plate 1 fits with the inner wall of the oral cavity. The medical staff then rotates the screw rod 202 in the positive direction, and the movable plate 205 threadedly connected to the screw rod 202 moves backward. The movable plate 205 drives the movable plate 204 to move backward. The tilt angle of the movable plate 204 increases and lifts up the upper support plate 2, so that the top surface of the upper support plate 2 and the bottom surface of the lower support plate 3 fit with the patient's teeth and support the patient's oral cavity at the same time. During the backward movement of the movable plate 204, the bottom of the movable plate 204 pushes the transmission plate 206, and the transmission plate 206 drives the stabilizing plate 207 to move under the push of the movable plate 204. The inclination angle of the stabilizing plate 207 changes with the change of the movable plate 204, so that the stabilizing plate 207 can assist in supporting the upper supporting plate 2. During the supporting process, the medical staff can change the inclination angle of the movable plate 204 by rotating the screw rod 202, thereby changing the size of the patient's mouth opening. The anti-dropping plates 5 on the upper supporting plate 2 and the lower supporting plate 3 fit the inner sides of the teeth in the patient's mouth to prevent the device from falling off the patient's mouth. When the patient's tongue needs to be limited, the medical staff can rotate the tongue depressor 303 out of the through groove 301 to press the patient's tongue to prevent the patient's tongue from moving around in the mouth. During the patient's biting process, the protective layer 6 protects the patient's teeth to improve the patient's comfort.

[0028] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
