Description

Technical Field

[0001] The present invention relates to the technical field of rehabilitation equipment, and in particular to a dysphagia rehabilitation device. Background Art

[0002] Swallowing dysfunction is a core functional disorder in patients with stroke sequelae (incidence is about 37%-78%), mid-to-late stage Parkinson's disease (incidence >80%), and sarcopenia in the elderly. Its pathological nature involves the dual mechanism of abnormal innervation of the suprahyoid muscles (genioglossus, styloglossus, etc.) and damaged oral sensory conduction pathways. Clinical studies have shown that when the contraction force of the tongue muscle drops below 18kPa (normal value: 30-45kPa), the risk of aspiration in patients will surge by 3.2 times (Dysphagia 2019;34:448), and the loss of oral mucosal temperature sensitivity (threshold >2°C) will directly lead to a swallowing trigger delay of more than 800ms (JNeurol Sci 2021;420:117263). This reveals the necessity of synergistic treatment of tongue muscle strength training and temperature stimulation from a neurophysiological perspective.

[0003] In tongue muscle strength training, tongue impedance training and left and right tongue extension training are usually used. In order to allow patients to extend their tongues left and right and fully stretch their tongues, existing dysphagia rehabilitation devices usually use negative pressure to suck the tip of the patient's tongue, and then pull it left and right to achieve the training effect. For example, the dysphagia rehabilitation training device for Parkinson's patients disclosed in the Chinese invention patent (CN117959137A) has a suction nozzle at the front end of the mounting rod, and the suction nozzle is connected to a negative pressure cylinder. The mounting rod can swing left and right under the action of the rotating component, and the patient's tongue tip can be adsorbed on the suction nozzle under the negative pressure of the negative pressure cylinder. In this way, the patient can perform left and right tongue extension training under the combined action of the negative pressure cylinder and the rotating component.

[0004] During the hot and cold stimulation training, an ice cotton swab is usually used to lightly touch specific parts such as the soft palate, posterior pharyngeal wall, tongue root, epiglottic valley, buccal mucosa, etc. After the stimulation, the patient is immediately guided to perform an empty swallowing action to strengthen the reflex. The heat stimulation is to wrap the tongue depressor with warm gauze and lightly touch the target area, which can promote local blood circulation and relieve muscle tension.

[0005] When performing the above rehabilitation training, it is necessary to use tongue muscle training equipment, ice cotton swabs and warm tongue depressors separately, which is cumbersome to operate and has low training efficiency. At present, there is no rehabilitation equipment on the market that can perform the above training in sequence. In response to this problem, the applicant invented a dysphagia rehabilitation device that can perform both tongue muscle stretching training and cold and hot stimulation training.

[0023] Reference Figure 1-16 The figure shows a preferred embodiment of the present invention.

[0024] Embodiment 1: A dysphagia rehabilitation device, including a supporting mechanism for supporting the whole device. The rehabilitation device of this embodiment is placed on a table for use. The specific structure is as follows: Figure 1 As shown, it is mainly composed of a base 1, a lifting plate 2 and a support plate 14. The lifting plate 2 is vertically installed on the base 1, and the end of the support plate 14 is fixedly installed on the lifting end side wall of the lifting plate 2. A double-layer circular fixing ring 6 is fixedly installed on the support plate 14. The two layers of fixing rings 6 are connected by a connecting block 16 at one end close to the lifting plate 2. A swing rod 7 is rotatably installed on the fixing ring 6. The rotation axis of the swing rod 7 is located at the end of the fixing ring 6 away from the lifting plate 2. A swing mechanism that drives the swing rod 7 to swing left and right in the horizontal direction is installed between the fixing rings 6; one end of the swing rod 7 is connected to the negative pressure tube 9 and is internally connected. A suction nozzle is installed at the end of the negative pressure tube 9 away from the swing rod 7. Under the action of negative pressure, the tip of the patient's tongue will be adsorbed on the suction nozzle. Combined with Figure 2 As shown, a liquid storage tank 13 is fixedly sleeved on the negative pressure tube 9; a partition 19 is installed in the liquid storage tank 13 to divide the interior thereof into two spaces, and a plurality of temperature regulating mechanisms are embedded in the partition 19 along its circumferential direction. In the initial state, the two spaces in the liquid storage tank 13 are filled with water, and the temperature regulating mechanisms release the heat and cold generated by them into the water on both sides of the partition 19 respectively.

[0025] In this embodiment, the heating and cooling of water is achieved by using a cooling plate, as shown in FIG. Figure 4As shown, the temperature regulating mechanism is mainly composed of a plurality of NP refrigeration semiconductors 17, two heat conducting plates 25 and a plurality of heat sinks 18. The plurality of refrigeration semiconductors 17 are distributed along the length of the partition 19, and the two ends of the refrigeration semiconductors 17 are respectively fixedly connected to the heat conducting plates 25, and the plurality of heat sinks 18 are respectively fixedly mounted on the side walls of the heat conducting plates 25. Among them, the refrigeration semiconductor 17 and the two heat sinks 18 are both embedded in the partition 19, and the heat sinks 18 are located on both sides of the partition 19. In this way, by using the principle that one end of the refrigeration semiconductor 17 cools and the other end heats, the water on both sides of the partition 19 can be cooled and heated respectively, and the liquids of the two temperatures are used for cold and hot stimulation training of the designated area of ​​the patient's mouth. With this structural design, the cold and heat generated by the refrigeration semiconductor can be fully utilized.

[0026] In order to be able to transport water of different temperatures to the suction nozzle, the present embodiment embeds two liquid supply pipes 21 in the side wall of the negative pressure pipe 9, and installs a pump body 20 on the negative pressure pipe 9. In order to be able to pump the water in the liquid storage tank 13 into the inner wall of the suction nozzle, and to be able to pump the water after the hot and cold stimulation training back into the liquid storage tank 13, the pump body 20 of the present embodiment adopts a peristaltic pump that can be reversed, and one end of the pump body 20 is connected to the end of the liquid supply pipe 21. In order to allow the pump body 20 to transport water of different temperatures in the liquid storage tank 13 respectively, the present embodiment sets a connecting mechanism that is sleeved on the negative pressure pipe 9 between the liquid storage tank 13 and the pump body 20. Combined with Figure 2 and Figure 3 As shown, the connecting mechanism is mainly composed of a control box 8, a driving gear 23, a driven gear 22 and a knob 12; the control box 8 is fixedly sleeved on the negative pressure tube 9, the driving gear 23 and the driven gear 22 are both located in the control box 8, the driven gear 22 is rotatably sleeved on the negative pressure tube 9, the axis of the driving gear 23 is connected to the knob 12, and the driving gear 23 and the driven gear 22 are meshed. Figure 3 As shown, two through holes 24 are opened on the circumference of different radii on the driven gear 22, and the two through holes 24 are respectively located on both sides of the negative pressure tube 9. The other end of the pump body 20 is connected to the circumferential radius positions of the two through holes 24 of the control box 8 through two pipes at the same time, and the two spaces of the liquid storage tank 13 are also connected to the circumferential radius positions of the two through holes 24. In this way, when the driven gear 22 rotates, the pump body 20 can be connected to the spaces on both sides of the partition 19 respectively, so that the pump body 20 can pressurize water of different temperatures in the two spaces into the inner wall of the suction nozzle, and achieve the effect of cold and hot stimulation training for the designated area of ​​the patient's oral cavity. The power input method of the connection mechanism of this embodiment is realized by manually rotating the knob 12, and can also be driven by a motor, so that it can be electrically adjusted so that the driven gear 22 can be rotated to the designated position, so that the pump body 20 can be connected to the two liquid storage spaces of the liquid storage tank 13 respectively.

[0027] In order to enable the nozzle to absorb the patient's tongue tip during left and right tongue extension training, the front opening of the nozzle is reduced during hot and cold stimulation training and the temperature is changed to the specified temperature of hot and cold stimulation. Figure 2 and Fig. 9 As shown, the suction nozzle of this embodiment is mainly composed of a fixed shell 11 and two rotating shells 10; the fixed shell 11 is a semi-spherical shell with an opening at the front end and a rear end connected to the negative pressure tube 9; two slide grooves 3 48 are opened in the upper and lower side walls of the fixed shell 11, and the two rotating shells 10 are respectively located in the slide grooves 3 48 and rotate along the slide grooves 3 48. The rotation axis of the rotating shell 10 is connected to the side wall of the fixed shell 11 by a torsion spring, so that the rotating shell 10 can automatically return to the initial position (inside the fixed shell 11) without pressurization. The ends of the two slide grooves 3 48 are respectively connected to the two negative pressure tubes 9, so that when the pump body 20 is pressurized, water can enter the slide groove 3 48 to push the rotating shell 10 to rotate and make it conflict (such as Figure 2 ). In order to allow the mobile shell with a closed front end to quickly reach the specified temperature of hot and cold stimulation, combined with Fig. 9 and Fig.10 As shown, in this embodiment, a liquid storage chamber 47 is opened in the rotating shell 10, and an elastic one-way valve is installed at one end of the liquid storage chamber 47 close to the liquid supply pipe 21. When the two rotating shells 10 are in contact, the pump body 20 continues to pressurize, and water will flush the elastic one-way valve and enter the liquid storage chamber 47. The rotating shell 10 is made of metal with high thermal conductivity. Considering the comprehensive cost, the rotating shell 10 of this embodiment is made of aluminum material with a thermal conductivity of about 237W / (m·K).

[0028] In order to allow the water in the liquid storage chamber 47 to return to the liquid storage tank 13 under the action of the pump body 20 for temperature adjustment, as shown in FIG. Fig.10 As shown, the elastic one-way valve of this embodiment is mainly composed of a sealing plate 49, a spring 1 50 and a push rod 53. For stable installation, the bottom of the push rod 53 is fixedly installed at the connection between the slide groove 3 48 and the liquid supply pipe 21 through a bracket 1 51. One end of the spring 1 50 is fixedly connected to the side wall of the through hole 2 52, and the other end is fixedly connected to the sealing plate 49. When the sealing plate 49 is separated from the push rod 53, the sealing plate 49 is stretched by the spring 1 50 to block the through hole 2 52. When the rotating housing 10 returns to the initial position ( Fig. 9 When the pump body 20 is in the position shown in the figure, the push rod 53 can push open the sealing plate 49, so that the liquid storage chamber 47 is connected with the liquid supply pipe 21, and the pump body 20 can transport the water in the liquid storage chamber 47 to the liquid storage tank 13.

The other end side wall of the rotating rod 4 is fixedly connected to the output end of the stepper motor 3. When the stepper motor 3 drives the rotating rod 4 to rotate, the slider 34 will move in the slot 32. Under the rotation of the rotating rod 4, the swing rod 7 can swing left and right along the horizontal direction. In this embodiment, in order to avoid interference between the vertical rod 5 and the rotating rod 4 and the support plate 14, as shown in FIG. Figure 1 As shown, in this embodiment, a through slot 15 is opened on the support plate 14.

[0030] In this embodiment, the negative pressure mechanism uses suction to make the front end of the nozzle in a negative pressure state. Figure 2 and Figure 5 As shown, the negative pressure mechanism is mainly composed of a connecting pipe 28, a piston 29, a sleeve 30, a negative pressure cylinder 27 and a threaded rod 26. The negative pressure cylinder 27 is fixedly mounted on the support plate 14, the connecting pipe 28 is embedded in the fixing ring 6, and one end of the connecting pipe 28 is inserted into the rotation axis of the swing rod 7 ( Figure 8 As shown), it is connected to the inside of the swing rod 7, the other end of the connecting pipe 28 is connected to the negative pressure cylinder 27, the piston 29 is slidably installed in the negative pressure cylinder 27, one end of the sleeve 30 is fixedly connected to the piston 29, and the sleeve 30 is sleeved on the threaded section of the threaded rod 26.

[0031] In order to enable the stepper motor 3 to drive the swing rod 7 to swing and the piston 29 to suck, a transmission device is arranged between the swing mechanism and the negative pressure mechanism.

The end of the power input shaft 38 is fixedly connected to the output end of the stepper motor 3; one end of the transmission rod 35 is fixedly connected to the rotating rod 4. In order for the transmission rod 35 to rotate stably, a support block (not marked in the figure) needs to be fixedly installed on the support plate 14. The transmission rod 35 passes through the support block, and the transmission rod 35 is rotatably sleeved on the end of the power input shaft 38. The worm 39 is also rotatably sleeved on the power input shaft 38. The end of the worm 39 is connected to the connecting block 16 in the form of a bearing. The synchronizer 37 is slidably sleeved on the power input shaft 38 and splined with the power input shaft 38; the two transmission wheels 45 are respectively fixedly sleeved on the transmission rod 35 and the worm 39. The two side surfaces of the synchronizer 37 and the side surface of the transmission wheel 45 close to the synchronizer 37 have meshing teeth. The translation unit can translate the synchronizer 37 so that the synchronizer 37 can be connected to the two transmission wheels 45 respectively through meshing teeth; the worm 39 meshes with the transmission gear 46. The axis of the transmission gear 46 is fixedly connected to the end of the threaded rod 26 , and the threaded rod 26 also plays a supporting role for the transmission gear 46 .

[0032] In order to control the synchronizer 37 to move left and right, the translation unit of this embodiment is as follows Figure 7 As shown, it is mainly composed of a crossbar 40, a screw rod 42, a servo motor 41 and a translation block 43; the end of the crossbar 40 is fixedly connected to the connecting block 16, a slide groove 44 is provided on the side of the crossbar 40 close to the synchronizer 37, the output end of the servo motor 41 is fixedly connected to the end of the screw rod 42, the translation block 43 is sleeved on the screw rod 42, an annular groove 36 is provided on the rotating side wall of the synchronizer 37, and the end of the translation block 43 is located in the annular groove 36, so that when the screw rod 42 rotates, the translation block 43 can be driven to move left and right, thereby driving the synchronizer 37 to translate left and right. In this way, the output power of the stepper motor 3 can be transmitted to the swing mechanism and the negative pressure mechanism respectively.

[0033] In this embodiment, the negative pressure tube 9 and the swing rod 7 can also be connected in a detachable manner, such as a threaded connection, so that the patient can perform hot and cold stimulation training on the designated area of ​​the oral cavity according to his own situation. At the same time, in this embodiment, each component can be powered by an external power cord or a battery. In addition, a control chip is used to control various electronic control operations.

[0034] Working principle: When the device is used for cold stimulation training, the pump body 20 is connected to the cavity storing ice water in the liquid storage tank 13 by rotating the knob 12. The pump body 20 is pressurized to make the water enter the chute 3 48, pushing the rotating shell 10 to rotate. When the two rotating shells 10 collide with each other, the pump body 20 continues to pressurize, and the ice water breaks the sealing plate 49 and enters the liquid storage chamber 1 47, thereby reducing the temperature of the rotating shell 10. In order to maintain this state, the communication channel between the pump body 20 and the liquid storage tank 13 can be cut off by rotating the knob 12. When the training is completed, the pump body 20 is reversely pressurized, and the ice water in the chute 3 48 first enters the liquid storage tank 13. The rotating shell 10 returns to the initial position under the action of the torsion spring. At this time, the push rod 53 will push open the sealing plate 49, so that the liquid storage chamber 1 47 is connected with the liquid supply pipe 21, so that the ice water in the liquid storage chamber 1 47 will be pressurized into the liquid storage tank 13.

[0035] When the patient's tongue muscles need to be trained to extend the tongue to the left and right, the servo motor 41 drives the lead screw 42 to rotate. Since the translation block 43 is sleeved on the lead screw 42, the translation block 43 drives the synchronizer 37 to move to the right, so that the synchronizer 37 engages with the transmission wheel 45 on the worm 39, and then drives the stepper motor 3 to rotate. The stepper motor 3 drives the power output shaft to rotate. At this time, the power is transmitted to the worm 39 through the synchronizer 37, so that the transmission gear 46 can rotate, and the transmission gear 46 drives the threaded rod 26 to rotate. Under the rotation of the threaded rod 26, the sleeve 30 pulls the piston 29 to move in the direction of the transmission gear 46. In this way, the entire connecting tube 28, the negative pressure tube 9 and the inside of the suction nozzle are all negative pressure, and the patient's tongue tip can be adsorbed on the suction nozzle. When the switch is pressed, the servo motor 41 rotates in the opposite direction and the translation block 43 moves to the left. At this time, the synchronizer 37 is engaged with the transmission wheel 45 on the transmission rod 35. In this way, when the stepper motor 3 rotates, the transmission rod 35 can be rotated, thereby driving the swing rod 7 to swing, thereby realizing the left and right tongue extension training of the tongue muscles.

[0036] Embodiment 2: A swallowing disorder rehabilitation device. The difference between this embodiment and embodiment 1 is mainly in the structure of the nozzle. Figure 11-Figure 14As shown, the suction nozzle of this embodiment is mainly composed of a fixed shell 2 54, a bracket 2 59, a fixed cylinder 62, a piston 2 64, a slider 2 58, a connecting rod 61, a spring 2 65, a plurality of transmission rods 2 60, a plurality of support rods 56 and two layers of flexible cloth 55. The fixed cylinder 62 is horizontally arranged in the fixed shell 2 54. In order to ensure the stable installation of the fixed shell 2 54, the bracket 2 59 is fixedly installed on the outer wall of the fixed cylinder 62, and the bracket 2 59 plays a supporting role. One end of the liquid inlet pipe 57 is connected to the fixed cylinder 62 and communicated with the inside of the fixed cylinder 62. The slider 2 58 is slidably sleeved on the liquid inlet pipe 57. At the same time, the other end of the liquid inlet pipe 57 is hinged to the plurality of support rods 56 along the circumferential direction. The two ends of the transmission rod 2 60 are respectively hinged to the support rod 56 and the slider 2 58. The flexible cloth 55 is attached to a plurality of support rods 56. When the slider 58 slides on the liquid inlet pipe 57, the structure of this part is similar to an umbrella frame opening or contracting inward. When fully unfolded, the ends of the support rods 56 will be like Fig.12 The flexible cloth 55 is completely attached to the inner wall of the fixed housing 54, and the entire flexible cloth 55 can block the opening at the front end of the fixed housing 54. When the slider 58 moves toward the fixed cylinder 62, as shown in FIG. Fig.13 As shown, the whole structure will shrink inwards, and the tongue can be adsorbed on the fixed housing 2 54 by means of negative pressure. The flexible cloth 55 of this embodiment is made of TPU coated cloth, which has the advantages of high elasticity, high wear resistance, and is not easy to crack after repeated bending. The temperature range is -50℃-80℃, which is conducive to the patient's cold and hot stimulation training.

[0037] like Fig.14 As shown, the second piston 64 slides along the inner wall of the fixed cylinder 62, and a through hole 3 63 is opened on the second piston 64. The elastic one-way valve of this embodiment is the same as the elastic one-way valve of embodiment 1, except that the spring 1 50 of the elastic one-way valve in this embodiment is installed on the through hole 3 63, and the push rod 53 is fixedly installed on the inner end of the fixed cylinder 62. The second piston 64 is connected to the second slider 58 through the connecting rod 61, and the second piston 64 is connected to the inner end of the fixed cylinder 62 through the second spring 65, and the end of the liquid supply pipe 21 is connected to the fixed cylinder 62. A sealed space is formed between the two layers of flexible cloth 55, and the sealed space is connected to the liquid inlet pipe 57. In this way, when the pump body 20 is continuously pressurized, the flexible cloth 55 can be first unfolded to block the front end of the fixed shell 2 54, and then water enters the cavity between the double layers of flexible cloth 55 to achieve rapid adjustment of the temperature of the front end of the suction nozzle.

[0038] Working principle: When cold stimulation training is performed, the pump body 20 pressurizes water into the fixed cylinder 62 through the liquid supply pipe 21 and pushes the piston 2 64 forward. Under the action of the connecting rod 61, the slider 2 58 is pushed forward and translated. The transmission rod 2 60 drives all the support rods 56 to expand outward. When the ends of the support rods 56 fit the inner wall of the fixed shell 2 54, the entire flexible cloth 55 blocks the front end of the fixed shell 2 54, thereby blocking the front end of the fixed shell 2 54. The pump body 20 continues to pressurize, and water will enter the cavity between the two layers of flexible cloth 55. In this way, the temperature of the front end of the nozzle will drop or rise rapidly, so that cold stimulation training can be performed on the designated area of ​​the patient's oral cavity. When the training is completed, the pump body 20 is reversely pressurized to transport the water in the fixed cylinder 62 to the liquid storage tank 13, and the piston 64 returns to the initial position under the pulling force of the spring 65. At this time, the push rod 53 pushes the sealing plate 49 open, so that the water in the double-layer flexible cloth 55 can be smoothly transported to the liquid storage tank 13.

[0039] Embodiment 3: A dysphagia rehabilitation device, such as Fig.15 and Fig.16 As shown, the difference between this embodiment and embodiment 1 is that the structure of the suction nozzle is different. In this embodiment, the suction nozzle is made of a flexible silicone 31 with two ends opened and in a spherical shell shape. The flexible silicone 31 is connected to the negative pressure tube 9. A second liquid storage cavity 33 is provided in the wall surface of the flexible silicone 31. The liquid supply tube 21 is connected to the second liquid storage cavity 33. When the pump body 20 continuously pressurizes water into the second liquid storage cavity 33, the front end opening of the flexible silicone 31 will shrink and become as shown in FIG. Fig.15 The shape shown, at this time, the temperature of the flexible silicone 31 will also change rapidly, so that the patient's oral designated area can be trained for hot and cold stimulation.

[0040] It should be emphasized that as long as the nozzle can close or reduce the opening at the front end under the pressurized action of cold or hot liquids, and can directly use cold or hot liquids to adjust the front end temperature of the nozzle, no matter what structure and material is used, such a nozzle is within the scope of protection of this application.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
