[0032] In order to make the purpose, technical solution and advantages of the embodiment of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Please refer to Figures 1 to 10 As shown: Embodiment 1: The present invention provides a dysphagia rehabilitation training device for the elderly, comprising a mounting seat 1 and a fixed bite block 5, wherein the fixed bite block 5 is fixedly mounted on the side of the mounting seat 1; and a training component, wherein the training component comprises a bite mechanism 2, a regulating mechanism 3 and a limit mechanism 4; The bite mechanism 2 includes a rotating bite block 201, a control seat 202, a support shaft 203 and a positioning screw 204. The rotating bite block 201 is rotatably connected to the inside of the mounting seat 1, and the control seat 202 is inserted into the inside of the mounting seat 1. The support shaft 203 is rotatably connected to the inside of the rotating shaft of the rotating bite block 201. The positioning screw 204 is rotatably connected to the side of the mounting seat 1, and the positioning screw 204 is screwed into the inside of the support shaft 203 through a rod body thread. The regulating mechanism 3 includes an adjusting screw 301 and a positioning plate 302. The adjusting screw 301 is rotatably connected to the top of the mounting seat 1, and the positioning plate 302 is inserted into the interior of the mounting seat 1. The adjusting screw 301 is screwed into the interior of the positioning plate 302 through a rod body thread. The limiting mechanism 4 includes a limiting rod 401 and a limiting block 402 . The limiting rod 401 is rotatably connected to the inside of the mounting seat 1 , and the limiting block 402 is inserted into the inside of the mounting seat 1 .

[0034] In the disclosed embodiment, a linkage gear 2011 is provided on the rotating shaft of the rotating bite block 201, and a linkage rack 2021 is provided on the side of the control seat 202. The gear teeth of the linkage rack 2021 and the linkage gear 2011 are engaged and transmitted. In use, when the training component is in the reset state (the rotating bite block 201 is not subjected to external force), the rotating bite block 201 and the fixed bite block 5 are in an open state, so that the lower teeth are against the bottom of the fixed bite block 5 and the upper teeth are against the top of the rotating bite block 201, so that the bite action training can be realized. A training top spring 3021 is provided at the bottom of the positioning plate 302, and the training top spring 3021 The two ends respectively rest against the bottom of the positioning plate 302 and the inside of the control seat 202. When biting, the rotating bite block 201 rotates downward. When the rotating bite block 201 rotates downward, the linkage gear 2011 can drive the control seat 202 to move upward and compress the training top spring 3021 through the linkage rack 2021, so that the training top spring 3021 can provide resistance for the entire bite training action to play the function of bite action training. When the bite force is released, the rotating bite block 201 can automatically rotate upward and reset under the action of the training top spring 3021, so as to prepare for training during the next bite. It is easy to use and flexible to train.

[0035] In the disclosed embodiment, the cross-section of the positioning disk 302 is a regular polygon, and a track groove 101 is provided inside the mounting seat 1. The positioning disk 302 is inserted into the track groove 101. During use, the training strength during bite training can be adjusted through the regulating mechanism 3. When the adjusting screw 301 is rotated, the adjusting screw 301 can drive the positioning disk 302 to move up and down inside the mounting seat 1 to change the use position through the rod body thread. The change in the use position of the positioning disk 302 changes the initial telescopic length of the training top spring 3021, that is, the size of the training strength obtained by the bite mechanism 2 through the training top spring 3021 during bite training. The regulation is convenient, and can be adapted to patients with different medical conditions for training and use, and has strong adaptability.

[0036] In the disclosed embodiment, a distraction training groove is provided inside the support shaft 203, and a distraction protrusion 2012 is provided inside the rotating shaft of the rotating bite block 201, and the distraction protrusion 2012 is inserted into the inside of the distraction training groove. The distraction training groove is composed of an annular avoidance groove 2031 and a spirally designed positioning groove 2032, and one end of the positioning groove 2032 is connected to the groove body of the avoidance groove 2031. When the rotating bite block 201 and the fixed bite block 5 are fitted with each other, the distraction protrusion 2012 is located at the connection between the positioning groove 2032 and the avoidance groove 2031. In use, the training component also has the function of distraction movement training, and can perform oral distraction on patients with difficulty in distraction movement (such as oral fibrosis) in a rigid support manner. Action training, when the training component is in the bite training function, the expansion protrusion 2012 will move inside the avoidance groove 2031, so that the support shaft 203 will not limit the rotation of the rotating bite block 201, and the bite action training can be stably performed. When the patient needs to be trained to open the mouth, the rotating bite block 201 and the fixed bite block 5 are switched to a closed state. At this time, the expansion protrusion 2012 will be at the connection between the avoidance groove 2031 and the positioning groove 2032. After keeping the rotating bite block 201 and the fixed bite block 5 closed to each other and inserting them into the patient's mouth, the positioning screw 204 can be rotated to realize the function of rigid expansion training of the patient's mouth, which is powerful.

[0037] In the embodiment of the present disclosure, a track rod 102 having a regular polygonal cross section is provided inside the mounting seat 1, and the track rod 102 is inserted into the inside of the support shaft 203. In use, when the rotating bite block 201 and the fixed bite block 5 are kept in a closed state and inserted into the patient's oral cavity and the positioning screw 204 is rotated, the support shaft 203 cannot rotate on its own inside the rotating bite block 201 due to the limiting and guiding effect of the track rod 102 on the support shaft 203, so that when the positioning screw 204 rotates, it can drive the support shaft 203 through the rod body thread. 3 axial movement, when the support shaft 203 moves, the positioning groove 2032 can drive the rotating bite block 201 to rotate and change the use angle through the opening protrusion 2012, thereby realizing the function of opening the patient's oral cavity, and the thread matching has the characteristic of one-way transmission. When the positioning screw 204 does not rotate, the support shaft 203 can always maintain the current use position, thereby positioning the use angle of the rotating bite block 201, and can always rigidly maintain the opening state to open the patient's oral cavity, which is convenient and flexible to use and stable to use.

[0038] In the embodiment of the present disclosure, a thread is provided on the outside of the rod body of the limit rod 401, and the limit rod 401 is screwed to the inside of the limit block 402 through the rod body thread. A limit stop block 2022 is provided on the side of the control seat 202, and the limit stop block 2022 is located directly above the side block of the limit block 402. In use, the maximum opening angle between the rotating bite block 201 and the fixed bite block 5 can be limited by the limit mechanism 4, so that it can be adapted to patients with different mouth sizes. When the limit rod 401 is rotated, the limit rod 401 can drive the limit block 402 to move up and down through the rod body thread. The limit block 402 can limit the maximum downward movement distance of the control seat 202 inside the mounting seat 1 by blocking the limit stop block 2022, that is, the maximum opening angle between the rotating bite block 201 and the fixed bite block 5. It is easy to adjust and control, which further improves the flexibility and adaptability of the device.

[0039] refer to Fig.11 As another embodiment of the rotating bite block 201, the rotating bite block 201 further comprises a first bite block group 20102 and a second bite block group 20103, and the first bite block group 20102 and the second bite block group 20103 are slidably arranged along the sliding groove 20101 on the rotating bite block. Preferably, a locking ball is arranged on one side of the first bite block group 20102 and the second bite block group 20103 close to the sliding groove, and correspondingly, a locking groove is arranged on the sliding groove, so that the first bite block group 20102 and the second bite block group 20103 slide to the corresponding position, and the relative position can be locked.

[0040] Likewise, the fixed bite block 5 may also be arranged according to the structure of the above-mentioned embodiment of the rotating bite block 201 .

[0041] As configured above, the fixed bite block 5 and the rotating bite block 201 can be appropriately adjusted according to the size of the patient's mouth shape, thereby improving the application scenario of the entire device.

[0042] Specific usage and function of this embodiment: In the present invention, the usage and training intensity of the training component are adjusted according to the actual condition of the patient. When the training component is in the reset state (the rotating bite block 201 is not subjected to external force), the rotating bite block 201 and the fixed bite block 5 are in an open state, so that the lower teeth are pressed against the bottom of the fixed bite block 5 and the upper teeth are pressed against the top of the rotating bite block 201, so that the training of the bite action can be realized. When biting, the rotating bite block 201 rotates downward. When the rotating bite block 201 rotates downward, the linkage gear 2011 can drive the control seat 202 to move upward and compress the training top spring 3021 through the linkage rack 2021, so that the training top spring 3021 can provide resistance for the entire bite training action to play a role in the bite action. The function of training is that when the bite force is released, the rotating bite block 201 can automatically rotate upward and reset under the action of the training top spring 3021, so as to prepare for the next bite training. The training force during bite training can be adjusted by the regulating mechanism 3. When the adjusting screw 301 is rotated, the adjusting screw 301 can drive the positioning plate 302 to move up and down inside the mounting seat 1 through the rod thread to change the use position. The change of the use position of the positioning plate 302 changes the initial telescopic length of the training top spring 3021, that is, the size of the training force obtained by the bite mechanism 2 through the training top spring 3021 during bite training. The regulation is convenient and can be adapted to patients with different medical conditions for training. The rotation of the bite block 20 can be limited by the limiting mechanism 4. 1 and the fixed bite block 5, so that it can be used for patients with different mouth sizes. When the limit rod 401 is rotated, the limit rod 401 can drive the limit block 402 to move up and down through the rod body thread. The limit block 402 can limit the maximum downward movement distance of the control seat 202 inside the mounting seat 1 by blocking the limit block 2022, that is, the maximum opening angle between the rotating bite block 201 and the fixed bite block 5. The training component also has the function of opening movement training, and can perform oral opening movement training for patients with difficulty in opening movement (such as oral fibrosis) in a rigid support manner. When the training component is in the bite training function, the opening protrusion 2012 will move inside the avoidance groove 2031 to support The shaft 203 will not limit the rotation of the rotating bite block 201, and can be used for stably biting action training. When the patient needs to be trained to open the mouth, the rotating bite block 201 and the fixed bite block 5 are switched to a closed state. At this time, the opening protrusion 2012 will be at the connection between the avoidance groove 2031 and the positioning groove 2032. After the rotating bite block 201 and the fixed bite block 5 are kept in a closed state and inserted into the patient's mouth, the positioning screw 204 can be rotated to realize the function of rigid opening training of the patient's mouth. When the rotating bite block 201 and the fixed bite block 5 are kept in a closed state and inserted into the patient's mouth and the positioning screw 204 is rotated, under the limiting and guiding effect of the track rod 102 on the support shaft 203,The support shaft 203 is unable to rotate inside the rotating bite block 201, so when the positioning screw 204 rotates, the support shaft 203 can be driven to move axially through the rod thread. When the support shaft 203 moves, the positioning groove 2032 can drive the rotating bite block 201 to rotate and change the use angle through the opening protrusion 2012, thereby realizing the function of opening the patient's oral cavity. The thread matching has the characteristic of one-way transmission. When the positioning screw 204 does not rotate, the support shaft 203 can always maintain the current use position, thereby positioning the use angle of the rotating bite block 201, and can always rigidly maintain the open state to open the patient's oral cavity.

[0043] In another embodiment, arc-shaped positioning grooves are provided on the top of the rotating bite block 201 and the bottom of the fixed bite block 5. The design of the positioning grooves facilitates the positioning of the patient's upper and lower teeth on the rotating bite block 201 and the fixed bite block 5, and facilitates the training of biting movements. There will be no slipping between the teeth and the rotating bite block 201 or the fixed bite block 5, thereby improving the stability of the device.
