Description

Technical Field

[0001] The present invention particularly relates to a dysphagia facial trainer. Background Art

[0002] Swallowing disorders refer to abnormalities or functional disorders in the structures of the oral cavity, pharynx, esophagus, etc., which cause patients to have difficulty eating and malnutrition, and have a negative impact on recovery.

[0003] More than 85% of patients with dysphagia can recover or alleviate their symptoms after treatment. However, if not treated in time and the best time for treatment is missed, the patient may be unable to eat normally for life and can only rely on nasogastric feeding, which reduces the patient's quality of life and prognosis of disease recovery. Therefore, early comprehensive functional rehabilitation training can promote the recovery of swallowing function and neurological function of patients with dysphagia, improve self-care ability, promote the patient's physical and mental health, and reduce the occurrence of complications.

[0004] For example, Chinese patent publication number CN218944273U provides a swallowing disorder trainer, comprising a medication delivery tube and a blocking rubber ring fixedly mounted around the outer periphery of the medication delivery tube. A suction silicone tip is provided at the front end of the medication delivery tube, a medication storage tank is provided on the outer side of the medication delivery tube, and an outer sealing cap is provided at the outer end of the medication storage tank. A connecting end plate is provided at the lower end of the medication delivery tube, and a finger pull sleeve is provided at the lower end of the connecting end plate. This trainer combines medication assistance with instrument training, thereby enhancing the overall training effect. Furthermore, during sucking exercises, the overall limiting pulling and blocking prevents accidental swallowing during training.

[0005] However, the existing devices for dysphagia have relatively simple functions and are not convenient for stimulating patients to swallow, resulting in poor recovery of patients' swallowing function. Therefore, in view of this, a dysphagia facial trainer is proposed to solve the above technical problems. Summary of the Invention

[0048] The present invention is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present invention and cannot be understood as limiting the scope of protection of the present invention. Those skilled in the art can make some non-essential improvements and adjustments to the present invention based on the above application content.

[0049] Example:

[0050] like Figure 1 、 2 As shown in Figures 3 and 5, the present invention provides a facial trainer for dysphagia, including a mounting base 101, a connecting frame 103 is provided on the mounting base 101, a tongue depressor 108 and two groups of lower dental trays 105 are provided at one end of the connecting frame 103, a supporting base 301 is hinged on the connecting frame 103, an elastic member 110 is provided between the supporting base 301 and the mounting base 101, and two groups of upper dental trays 304 are provided at the other end.

[0051] When the trainer is in use, the upper and lower teeth can be clamped in the upper dental tray 304 and the lower dental tray 105 respectively. The patient can train the bite muscles through the biting action, thereby exercising the mouth closing function. During the biting process, the support seat 301 does not move, and the connecting frame 103 rotates along the hinge point between it and the support seat 301. The elastic member 110 applies resistance to the movement of the connecting frame 103 to improve the training effect. The tongue can also be pressed against the tongue depressor 108. The tongue depressor 108 can be made of elastic material. The tongue muscles are trained through the tongue depressor 108 to further improve the training effect.

[0052] like Figure 1 、 2 As shown in Figures 4 and 5, in this embodiment, the mounting base 101 and the connecting frame 103 are connected via a telescopic rod 102. Connecting rods 201 are hinged at both ends of the mounting base 101. The hinge points of the connecting rods 201 and the mounting base 101 are equipped with torsion springs. The ends of the connecting rods 201 are equipped with curved massage rods 202, which are circumferentially arranged with multiple groups of rotatable massage wheels 203. One group of massage rods 202 has a Velcro closure 204 at its end, while the other group of massage rods 202 has a connecting frame 205 at its end. The Velcro closure 204 has a looped surface that extends through the connecting frame 205 and adheres to its hooked surface after folding.

[0053] The two sets of massage rods 202 can be opened and placed around the patient's neck. The torsion springs control the opening of the two sets of massage rods 202. The Velcro 204 is then pulled through the connecting frame 205 and bonded to the two sets of massage rods 202. The multiple sets of massage wheels 203 contact the patient's neck. The engagement movement drives the connecting frame 103 to move, causing the two sets of massage rods 202 to move and massage and relax the patient's neck muscles, promoting the recovery of swallowing muscles and improving the effectiveness of swallowing function training. The distance between the mounting base 101 and the connecting frame 103 can be adjusted by controlling the telescopic rod 102 to extend and retract, making it easier for patients of different body shapes to use. The telescopic rod 102 can be electrically or hydraulically controlled, or in other configurations.

[0054] like Figure 1 、 2 As shown in Figures 3 and 5, in this embodiment, a liquid storage tank 306 is further provided on the support base 301, and a supply assembly is provided between the connecting frame 103 and the support base 301. The supply assembly pumps the liquid in the liquid storage tank 306 into the patient's mouth when the connecting frame 103 rotates. The supply assembly includes a piston cylinder 106 provided on the connecting frame 103, a through hole 109 is provided on the tongue depressor 108, and the through hole 109 is connected to the piston cylinder 106 via a one-way valve. A communicating pipe 107 is provided on the liquid storage tank 306, and one end of the pipe 107 is connected to the piston cylinder 106 via a one-way valve. A flexible rod 302 is provided at the bottom of the support base 301, and a piston block 303 is provided at the end of the flexible rod 302. The piston block 303 is arranged in the piston cylinder 106 along the axis of the piston cylinder 106.

[0055] Syrup, glucose solution, or other liquid, preferably a cryogenic liquid, is injected into the liquid reservoir 306. During the bite movement, the support base 301 and the connecting frame 103 open and close, driving the piston block 303 to slide within the piston cylinder 106. The flexible rod 302 is configured to accommodate changes in the angle between the support base 301 and the connecting frame 103. As the piston block 303 slides, negative pressure draws liquid from the liquid reservoir 306 and delivers it to the through hole 109. The liquid is then discharged into the patient's mouth, stimulating the patient's swallowing muscles to initiate swallowing. This makes the entire swallowing process more comfortable and enhances the training effect.

[0056] like Figure 1 、 Figures 5 to 7As shown, in this embodiment, a mounting bracket 501 is provided on a support base 301. A housing 601 is slidably mounted on the mounting bracket 501. A massage plate 603 is disposed within the housing 601. The massage plate 603 is connected to the connecting bracket 103 via a drive mechanism, which converts the movement of the connecting bracket 103 into reciprocating rotation of the massage plate 603. A mounting sleeve 305 is provided on the support base 301. The mounting bracket 501 is fixedly mounted on the mounting sleeve 305. A connecting bracket 602 is provided on one side of the housing 601. The connecting bracket 602 is slidably mounted on the mounting bracket 501. The mounting bracket 501 is made of a flexible material.

[0057] After the device is worn, the two sets of mounting frames 501 can apply a certain amount of pressure inward through the flexible mounting frame 501, and the connecting seat 602 on one side of the shell 601 can be slid on the mounting frame 501 to adjust the position of the massage plate 603, so that the massage plate 603 on one side of the shell 601 fits the position of the patient's masseter muscle.

[0058] like Figures 5 to 7 As shown, in this embodiment, the driving mechanism includes a lifting frame 502 that is liftable and arranged in the mounting frame 501, and a first linkage component connected to the lifting frame 502 and the connecting frame 103 is arranged in the mounting sleeve 305, and the rotation of the connecting frame 103 is converted into driving the lifting frame 502 to move up and down through the first linkage component. The first linkage component includes a first gear 104 fixedly arranged at the hinge between the connecting frame 103 and the support seat 301, a rotatable idler wheel 404 is arranged in the mounting sleeve 305, and the idler wheel 404 is meshed with the first gear 104, and a second gear 403 that is rotatable in the mounting sleeve 305 and meshed with the idler wheel 404 is rotatably arranged, and the number of teeth of the second gear 403 is smaller than that of the first gear 104, and a coaxial driving disk 401 is provided on the second gear 403, and a driving column 402 is eccentrically arranged on the driving disk 401, and a sliding frame 503 is arranged on the lifting frame 502, and the driving column 402 is slidably arranged in the sliding frame 503.

[0059] During the engaging movement, the first gear 104 rotates relative to the support base 301, thereby driving the second gear 403 to rotate to a greater extent through the idler gear 404. During the rotation, the second gear 403 drives the driving column 402 to rotate, and then the lifting frame 502 is controlled to rise and fall in the mounting frame 501 through the cooperation between the driving column 402 and the sliding frame 503.

[0060] like Figures 5 to 7As shown, in this embodiment, the massage tray 603 is equipped with a second linkage assembly connected to the lifting frame 502. This second linkage assembly converts the lifting of the lifting frame 502 into rotation of the massage tray 603 along its axis. The second linkage assembly includes two sets of limiting posts 604 spaced apart on either side of the massage tray 603, with the lifting frame 502 positioned between the two sets of limiting posts 604. During the lifting and lowering process of the lifting frame 502, the two sets of limiting posts 604 drive the massage tray 603 to rotate. During the rotation of the massage tray 603, the massage posts on one side of the massage tray 603 massage and relax the patient's bite muscles, further enhancing the rehabilitation effect.

[0061] Specific usage and beneficial effects of the present invention:

[0062] During use, the device injects syrup or glucose solution into the reservoir 306, then clamps the upper and lower teeth into the upper and lower dental trays 304 and 105, respectively. The elastic member 110 supports the support base 301 and the connecting frame 103. The patient can control the connecting frame 103 to rotate along its hinge with the mounting base 101 by biting, training the occlusal muscles and improving the ability to close the mouth. The tongue can press against the tongue depressor 108 to train the tongue muscles, making swallowing more effective. During rotation, the connecting frame 103 pumps the liquid from the reservoir 306 into the patient's mouth via a supply assembly, stimulating the tongue root and prompting the patient to swallow. The housing 601 can also be slid into contact with the patient's occlusal muscles. While controlling the opening and closing of the upper and lower teeth, the drive mechanism converts the motion of the connecting frame 103 into reciprocating rotation of the massage plate 603, gently massaging spastic muscles and further improving the patient's recovery efficiency. Training with this trainer is simple to use and has rich training functions. It can exercise in multiple directions simultaneously, thereby effectively improving the patient's ability to recover from swallowing function.

[0063] The basic principles, main features, and advantages of the present invention are shown and described above. It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above. Modifications and improvements may be made based on the present invention, as will be apparent to those skilled in the art. Therefore, such modifications and improvements, without departing from the spirit of the present invention, are intended to fall within the scope of protection claimed in the present invention.
