Description

Technical Field

[0001] The invention relates to the technical field of swallowing function training, and in particular to an oral-facial swallowing function training device. Background Art

[0002] Dysphagia is a common complication of diseases such as stroke and brain trauma. It is mainly manifested as damage to the lips, upper and lower jaws, tongue, soft palate, throat, esophageal sphincter or esophageal function during eating, which makes it impossible to safely and effectively transport food from the mouth to the stomach to obtain sufficient nutrition and water. This not only affects the patient's daily life, but may also lead to serious complications such as aspiration, aspiration pneumonia, dehydration, malnutrition, etc., endangering the patient's life. For patients with dysphagia and oral-facial dysfunction, tongue, lip, and mandibular dysfunction will occur before the oral bolus is transmitted, resulting in impaired autonomous swallowing function. At the same time, delayed swallowing initiation and oral bolus transmission disorders will occur, aggravating the degree of dysphagia and affecting the rehabilitation of swallowing function. Patients with dysphagia and oral-facial dysfunction cannot be intervened according to general treatment methods. On the basis of swallowing treatment, oral-facial function training must be added to gradually let the patient relearn the movement pattern of oral-facial muscles, improve their oral motor function and promote the recovery of swallowing function. Therefore, oral-facial rehabilitation training is a necessary measure to improve neurological dysphagia.

[0036] During the specific implementation, the patient holds the shell 1 so that the bite plate 21 enters the patient's oral cavity, so that the two bite plates 21 respectively abut the patient's upper and lower teeth, and the patient performs a biting action, driving the ends of the bite plates 21 located outside the shell 1 to abut each other, thereby driving the two bite plates 21 to rotate, so that the ends of the two bite plates 21 located inside the shell 1 are separated from each other, and in the process of separation, the elastic force of the elastic telescopic member 23 applies a resistance to the bite plates 21, so as to perform bite training in the oral-facial swallowing function; and when it is necessary to adjust the resistance of the bite plate 21 according to the patient's condition, the elastic force adjustment mechanism 3 is controlled to operate, and the elastic force adjustment mechanism 3 adjusts the position of the other end of the elastic telescopic member 23 in the length direction of the bite plate 21, so as to adjust the elastic force of the elastic telescopic member 23, thereby realizing the adjustment of the resistance of the bite plate 21, so that the training device can adapt to patients with different conditions.

[0037] See also Figure 1-Figure 7In other embodiments, the width of the bite plate 21 is adjustable; by adjusting the width of the bite plate 21, it can adapt to patients with different mouth sizes, thereby improving the applicability of the training device.

[0038] See also Figure 1-Figure 7In other embodiments, a limiting mechanism 4 is also included, and the limiting mechanism 4 can limit the relative sliding of the first bite member 211 and the second bite member 212; through the setting of the limiting mechanism 4, after the width adjustment of the bite plate 21 is completed, the relative position between the first bite member 211 and the second bite member 212 is limited by the limiting mechanism 4, so as to fix the width of the bite plate 21. Furthermore, the limiting mechanism 4 includes: a sleeve 41, a sliding connector 42, an abutment 43 and a plug-in connector 44; in the width direction of the first bite member 211, a circular groove 213 that is plugged into and matched with the sleeve 41 is provided on one side close to the second bite member 212; one end of the sleeve 41 is fixedly mounted on the second bite member 212, and the other end of the sleeve 41 is slidably plugged into the circular groove 213; the shaft 22 is rotatably mounted on the housing 1, and the shaft 22 extends coaxially. The sliding connection member 42 is sleeved on the rotating shaft 22 and is slidably connected to the rotating shaft 22 along the length direction of the rotating shaft 22; the sliding connection member 42 includes a threaded section 421 and a shoulder section 422 arranged in the length direction; the outer side of the threaded section 421 is threadedly connected to the inner side of the sleeve 41; the shoulder section 422 close to the threaded section 421 can abut against the end of the sleeve 41; and the shoulder section 422 is located in the circular groove 213; the abutment member 4 3 is slidably mounted on the sliding connector 42 along the length direction of the sliding connector 42; an abutting portion 431 is provided on the abutting member 43, and the abutting portion 431 is located between the shaft shoulder of the shaft shoulder section 422 and the end of the sleeve 41; an isosceles triangle pushing portion 432 is provided on the side of the abutting member 43 away from the sleeve 41; the plug-in member 44 is slidably mounted on the sliding connector 42 along the radial direction of the sliding connector 42, and the plug-in member 44 is located on the side of the abutting member 43 away from the sleeve 41, and a pushing groove 441 is provided on the side of the plug-in member 44 close to the abutting member 43 to cooperate with the isosceles triangle pushing portion 432; an isosceles triangle plug-in portion 442 is provided on the side of the plug-in member 44 away from the axial direction of the sliding connector 42; a plurality of annular abutting grooves 214 are opened in the length direction of the inner side wall of the circular groove 213, and the annular abutting grooves 214 are arranged in cooperation with the isosceles triangle plug-in portion 442; specifically, the cross section of the annular abutting groove 214 is arranged in an isosceles triangle.

[0039] When the width of the bite plate 21 needs to be fixed, the rotating shaft 22 is rotated and the first bite member 211 and the second bite member 212 are limited to rotate by hand. The rotating shaft 22 drives the sliding connection member 42 to rotate, so that the threaded section 421 on the sliding connection member 42 enters the sleeve 41. Under the action of the thread, the sliding connection member 42 moves toward the sleeve 41 on the rotating shaft 22, so that the distance between the shoulder of the shoulder section 422 and the end of the sleeve 41 gradually decreases, so that the abutment portion 431 can be pushed to move toward the direction of the plug-in member 44, thereby driving the isosceles triangle pushing portion 432 toward the pushing groove 441 on the plug-in member 44. Sliding inward, under the guidance of the isosceles triangle pushing portion 432 and the inclined surface of the pushing groove 441, the isosceles triangle pushing portion 432 pushes the plug-in component 44 to move toward the nearest annular abutment groove 214, so that the isosceles triangle plug-in component 442 is plugged into the annular abutment groove 214; in this way, the first bite component 211 can be connected and fixed by plugging the isosceles triangle plug-in component 442 into the annular abutment groove 214; the second bite component 212 is connected and fixed by threading the threaded section 421 with the sleeve 41, so as to limit the relative sliding of the first bite component 211 and the second bite component 212, thereby achieving the fixation of the width of the bite plate 21.

[0040] When it is necessary to adjust the width of the bite plate 21, rotate the shaft 22 in the opposite direction. Under the action of the thread on the threaded section 421, the shaft 22 drives the sliding connection member 42 to slide out of the sleeve 41, so that the distance between the shoulder of the shoulder section 422 and the end of the sleeve 41 gradually increases; then push the first bite member 211 to slide, so as to adjust the width of the bite plate 21, and make the inclined surface of the annular abutment groove 214 on the inner wall of the circular groove 213 push the isosceles triangle plug-in part 442 to reset, and the inclined surface of the pushing groove 441 on the plug-in part 44 pushes the isosceles triangle pushing part 432 to reset, so as to realize the reset of the abutment member 43.

[0041] See also Figure 1-Figure 7 In other embodiments, the distance between the two rotating shafts 22 is adjustable. Since the patient has a small force when opening his mouth at the beginning of training, the distance between the upper and lower teeth is small; after gradual training, the force gradually recovers, and when the patient opens his mouth, the distance between the upper and lower teeth will gradually increase. Therefore, by adjusting the distance between the two rotating shafts 22, the distance between the two bite plates 21 can be adjusted, so as to adapt to different training stages. After adjusting the distance between the bite plates 21, the position of the other end of the elastic telescopic member 23 in the length direction of the bite plate 21 is adjusted by the elastic force adjustment mechanism 3, so as to ensure that the resistance to the bite plate 21 is sufficient.

[0042] See also Figure 1-Figure 7In other embodiments, the spacing between the two rotating shafts 22 is adjusted by a spacing adjustment mechanism 5, which includes a base 51, a nut seat 52, and a bidirectional screw 53; the rotating shaft 22 is rotatably mounted on the base 51, and the base 51 is slidably mounted on the housing 1; the nut seat 52 is fixedly connected to the base 51; the bidirectional screw 53 is rotatably mounted on the housing 1; and the two nut seats 52 are mounted on the bidirectional screw 53. In specific implementation, the bidirectional screw 53 is rotated, and the bidirectional threads drive the two bases 51 to move toward each other through the nut seat 52, so as to adjust the spacing between the two rotating shafts 22, and then realize the adjustment of the spacing between the two bite plates 21. Furthermore, the elastic force adjustment mechanism 3 includes: a threaded rod 31, a connecting plate 32 and a slider 33; the threaded rod 31 penetrates the housing 1 and is threadedly connected to the housing 1, and the threaded rod 31 is arranged along the length direction of the bite plate 21; the connecting plate 32 is slidably installed in the housing 1 along the length direction of the bite plate 21, and the connecting plate 32 is arranged along the length direction of the rotating shaft 22, and the threaded rod 31 and the connecting plate 32 are rotatably connected; the end of the elastic telescopic member 23 away from the bite plate 21 is fixedly installed with a slider 33, and the slider 33 is slidably installed on the connecting plate 32 along the length direction of the connecting plate 32. In specific implementation, the threaded rod 31 is rotated, and the threaded rod 31 drives the connecting plate 32 to slide, thereby pulling the elastic telescopic member 23 through the slider 33, thereby realizing the adjustment of the elastic force of the elastic telescopic member 23; and when the first bite member 211 and the second bite member 212 slide, they will drive the elastic telescopic member 23 to slide, and the slider 33 will slide adaptively on the connecting plate 32, thereby reducing the tilt of the elastic telescopic member 23.

[0043] See also Figure 1-Figure 7 In another embodiment, elastic membranes 6 are respectively provided on opposite sides of the bite plate 21 in the width direction, and both ends of the elastic membranes 6 are respectively fixedly mounted on the two bite plates 21; the patient inserts the tongue deep into the space between the two bite plates 21, and the patient's tongue pushes the elastic membrane 6, thereby pushing the patient's tongue for rehabilitation training, which is more conducive to the recovery of swallowing function.
