Description

Technical Field

[0001] The present invention relates to the field of pharyngeal stimulation devices, and more particularly to a pharyngeal stimulation device for rehabilitation training of elderly people with dysphagia. Background Art

[0002] Dysphagia refers to the process in which food cannot be safely and effectively transported to the stomach due to damage to the structure or function of organs such as the mouth, throat, and esophagus, that is, food intake and swallowing disorder. Dysphagia is a common clinical symptom. Various diseases can cause dysphagia, including central nervous system diseases, peripheral neuropathy, muscle diseases, organic lesions of the oral cavity, diseases of the digestive system and respiratory system, and patients after oropharyngeal radiotherapy, chemotherapy, and surgery may all experience dysphagia.

[0003] However, in the prior art, such as the Chinese patent "CN218248346U", a pharyngeal stimulation device for swallowing disorder rehabilitation training is provided, including a shell, a stud is installed on the top of the shell at the left end of the shell, a nut is provided at the bottom of the stud, a swivel is located on the left side of the shell, a cold rod is installed on the left side of the swivel, a hollow column is connected to the bottom of the swivel, a pressing plate is connected to the bottom of the hollow column, a motor is fixedly connected to the inside of the shell, a rotating shaft is provided at the movable end of the motor, and a first bevel gear is fixedly connected to the right side of the rotating shaft.

[0004] However, in the above patent, the patient needs to keep his mouth open for a long time during rehabilitation training. Due to the lack of a mechanism to support the patient's mouth, the patient's facial muscles will feel fatigued when the mouth is open for a long time, causing the patient to be more tired during rehabilitation training. In addition, because the positions of the pressing plate and the cold rod are always in a parallel relationship, if the medical staff moves the cold rod inside the patient's mouth, the position of the pressing plate will inevitably change. At this time, the pressing force of the pressing plate on the patient's tongue root will be weakened, and it is impossible to stimulate different positions of the throat while pressing the tongue root stably. This is inconvenient and has certain limitations when used.

[0005] Therefore, in view of the above technical problems, it is necessary to provide a pharyngeal stimulation device for rehabilitation training of elderly people with dysphagia. Summary of the invention

[0006] The purpose of the present invention is to provide a pharyngeal stimulation device for rehabilitation training of elderly people with dysphagia, so as to solve the problems raised in the above-mentioned background technology.

[0007] In order to achieve the above purpose, the technical solution provided by an embodiment of the present invention is as follows:

[0008] A pharyngeal stimulation device for rehabilitation training of elderly people with dysphagia comprises a base, a tongue depressor is fixedly connected to the bottom of the base, serrated plates are fixedly connected to both sides of the outer wall of the base, sliding blocks are slidably connected to one side of the two serrated plates, the two sliding blocks are serrated on one side close to the serrated plates and have the same size as the serrations on the surface of the serrated plates and in opposite directions, a limiting rod is fixedly connected to one side of the two sliding blocks, a No. 1 spring is fixedly connected between the two limiting rods, a connecting rod is rotatably connected to one side of the base, a support rod is rotatably connected to one side of the sliding block, and an end of the support rod away from the sliding block is rotatably connected to the middle part of the connecting rod.

[0009] As a further improvement of the present invention, a bite plate is rotatably connected inside the connecting rod, and the bite plate is in an arc shape.

[0010] As a further improvement of the present invention, the base is internally slidably connected to a mounting seat, the mounting seat is internally rotatably connected to a first rotating block and a second rotating block, and one end of the first rotating block and the second rotating block located outside the mounting seat are fixedly connected to a missing gear.

[0011] As a further improvement of the present invention, a No. 2 spring is fixedly connected to the outside of the mounting seat, one end of the No. 2 spring is fixedly connected to a clamping block, one end of the clamping block is clamped with the outer wall of the missing gear, the outer wall of the missing gear is fixedly connected to a long rod, and the end of the long rod is fixedly connected to a paddle.

[0012] As a further improvement of the present invention, a sphere is arranged inside the mounting seat, one side of the No. 1 rotating block and the No. 2 rotating block are both connected to the rotation of the sphere, one side of the sphere is fixedly connected to a stimulation block, the stimulation block is spherical, and both the sphere and the stimulation block are hollow structures and are internally connected.

[0013] As a further improvement of the present invention, a mounting block is fixedly connected to the top of the base, a sliding rod is slidably connected to the middle of the mounting block, the sliding rod and the outer wall of the base are slidably connected, a No. 3 spring is sleeved on the outer wall of the sliding rod, the No. 3 spring is located inside the mounting block, and a stopper is fixedly connected to the outer wall of the sliding rod, one of the stoppers is located inside the mounting block, and the other stopper is located outside the mounting block.

[0014] As a further improvement of the present invention, a limiting hole is provided on the outer wall of the mounting seat, and one end of the sliding rod is clamped inside the limiting hole.

[0015] As a further improvement of the present invention, a water storage box and a water pump are installed inside the mounting seat.

[0016] As a further improvement of the present invention, the input end of the water pump is fixedly connected to one side of the water storage box.

[0017] As a further improvement of the present invention, the output end of the water pump is fixedly connected to a hose, and one end of the hose away from the water pump is connected to one end of the ball.

[0018] Compared with the prior art, the advantages of the present invention are:

[0019] 1. In the present invention: when the medical staff pushes the sliding block, the connecting rod rotates at a certain angle, and then the patient can bite the upper and lower bite plates. After the patient bites the bite plates, the bite plates will apply an extrusion force to the sliding block, and the direction of the extrusion force is from the tongue depressor to the sliding block. Under the action of the mutual engagement of the sliding block and the serrated plate, the bite plate can be limited to avoid the secondary rotation of the connecting rod. At this time, the support for the patient's oral cavity can be completed, and the bite plate can be rotated at a certain angle, so that the patient's teeth can move within a certain range. Through this design, the patient can avoid facial muscle fatigue caused by long-term mouth opening when training the throat muscles, reduce the intensity of the patient's training, and thus improve the efficiency of rehabilitation training for the patient's throat muscles.

[0020] 2. In the present invention: if it is necessary to stimulate different positions inside the patient's throat, the staff can press the paddle, and the paddle will drive the missing gear to rotate after being pressed. During the rotation of the missing gear, the No. 1 rotating block or the No. 2 rotating block will be driven to rotate. When the No. 1 rotating block or the No. 2 rotating block rotates, it will drive the ball to rotate. When the No. 1 rotating block rotates, the ball will drive the stimulation block to swing horizontally, and when the No. 2 rotating block rotates, the ball will drive the stimulation block to swing vertically. During the rotation of the missing gear, the outer wall of the missing gear will squeeze the card block, and the No. 2 spring of the card block will shrink after being squeezed. When the medical staff stops paddleing, that is, the missing gear stops rotating, under the action of the No. 2 spring, the card block will be re-connected to the groove of the missing gear directly in front of it, so that the stimulation block can stimulate different positions inside the patient's throat while ensuring that the tongue depressor does not move, thereby improving the stimulation range of the patient's throat muscles by the stimulation block.

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0031] Embodiment 1:

[0032] See also Figure 1-7A pharyngeal stimulation device for rehabilitation training of elderly people with swallowing disorders comprises a base 1, a tongue depressor 11 is fixedly connected to the bottom of the base 1, a serrated plate 18 is fixedly connected to both sides of the outer wall of the base 1, a sliding block 12 is slidably connected to one side of the two serrated plates 18, the two sliding blocks 12 are serrated on one side close to the serrated plate 18 and have the same size and opposite direction of the serrations on the surface of the serrated plate 18, a limiting rod 16 is fixedly connected to one side of the two sliding blocks 12, a No. 1 spring 17 is fixedly connected between the two limiting rods 16, a connecting rod 13 is rotatably connected to one side of the base 1, a supporting rod 14 is rotatably connected to one side of the sliding block 12, an end of the supporting rod 14 away from the sliding block 12 is rotatably connected to the middle part of the connecting rod 13, a bite plate 15 is rotatably connected to the inside of the connecting rod 13, and the bite plate 15 is arc-shaped. The seat 1 is internally slidably connected to the mounting seat 2, and the mounting seat 2 is internally rotatably connected to a first rotating block 21 and a second rotating block 22. One end of the first rotating block 21 and the second rotating block 22 located outside the mounting seat 2 are fixedly connected to a missing gear 23, and the outside of the mounting seat 2 is fixedly connected to a second spring 25, and one end of the second spring 25 is fixedly connected to a clamping block 24, and one end of the clamping block 24 is clamped with the outer wall of the missing gear 23, and the outer wall of the missing gear 23 is fixedly connected to a long rod 26, and the end of the long rod 26 is fixedly connected to a paddle 27. A ball 28 is arranged inside the mounting seat 2, and one side of the first rotating block 21 and the second rotating block 22 are both connected to the rotation of the ball 28, and one side of the ball 28 is fixedly connected to a stimulation block 29, which is spherical, and both the ball 28 and the stimulation block 29 are hollow structures and are internally connected.

[0033] In this embodiment, during use, the facial muscles of the patient will feel tired after opening the mouth for a long time. If the patient's mouth needs to be supported to reduce the fatigue caused by the patient's long-term opening of the mouth, the medical staff can push the two sliding blocks 12 simultaneously along the direction of the stimulation block 29. Because one side of the sliding block 12 coincides with one side of the serrated plate 18, and the two sliding blocks 12 are pushed, when the sliding blocks 12 are displaced in the vertical direction along the inclined surface of the serrated plate 18, the No. 1 spring 17 will be elastically deformed and stretched. Because the interior of the No. 1 spring 17 is provided with a telescopic rod, the two limit rods can be pushed. 16 plays a good synchronous limiting role. Through the extension and retraction of the telescopic rod inside the first spring 17, the sliding block 12 can push the connecting rod 13 through the support rod 14 during the movement. The connecting rod 13 will rotate after being pushed by the support rod 14. When the connecting rods 13 on both sides of the base 1 rotate, the distance between the two bite plates 15 will increase. After the two bite plates 15 are adjusted to the required angle position, the patient can bite the two bite plates 15 at the same time. After the bite plates 15 are bitten by the patient, a squeezing force will be applied to the sliding block 12, and the direction of the squeezing force is from the tongue depressor 11 to the direction where the sliding block 12 is located. Under the action of the mutual engagement of the block 12 and the serrated plate 18, the bite plate 15 can be limited to prevent the connecting rod 13 from rotating twice. After the tongue depressor 11 is used to press the patient's tongue, if it is necessary to stimulate different positions inside the patient's throat, the staff can press the paddle 27. After being pressed, the paddle 27 will drive the missing gear 23 to rotate. During the rotation of the missing gear 23, the No. 1 rotating block 21 or the No. 2 rotating block 22 will be driven to rotate. When the No. 1 rotating block 21 or the No. 2 rotating block 22 rotates, it will drive the ball 28 to rotate. When the No. 1 rotating block 21 rotates, the ball 28 will be driven to rotate. The ball 28 will drive the stimulation block 29 to swing horizontally. When the No. 2 rotating block 22 rotates, the ball 28 will drive the stimulation block 29 to swing vertically. During the rotation of the missing gear 23, the outer wall of the missing gear 23 will squeeze the block 24. After being squeezed, the No. 2 spring 25 will shrink. When the medical staff stops turning the paddle 27, that is, the missing gear 23 stops rotating, the block 24 will be re-engaged in the groove of the missing gear 23 directly in front of it under the action of the No. 2 spring 25, so that the stimulation block 29 can stimulate different positions inside the patient's throat, thereby improving the efficiency of rehabilitation training.

[0034] Embodiment 2:

[0035] See also Figure 1-7A pharyngeal stimulation device for rehabilitation training of elderly people with swallowing disorders, a mounting block 3 is fixedly connected to the top of the base 1, a sliding rod 31 is slidably connected to the middle part of the mounting block 3, the sliding rod 31 is slidably connected to the outer wall of the base 1, the outer wall of the sliding rod 31 is sleeved with a No. 3 spring 32, the No. 3 spring 32 is located inside the mounting block 3, the outer wall of the sliding rod 31 is fixedly connected with a stopper 33, one stopper 33 is located inside the mounting block 3, and the other stopper 33 is located outside the mounting block 3, a limiting hole 34 is provided on the outer wall of the mounting seat 2, one end of the sliding rod 31 is clamped inside the limiting hole 34, a water storage box 35 and a water pump 36 are installed inside the mounting seat 2, the input end of the water pump 36 is fixedly connected to one side of the water storage box 35, the output end of the water pump 36 is fixedly connected to a hose 37, and the end of the hose 37 away from the water pump 36 is connected to one end of the ball 28.

[0036] In this embodiment, if the medical staff needs to extend the stimulation block 29 inside the patient's mouth, the medical staff can first pull the sliding rod 31 upwards. After being pulled, the sliding rod 31 will slide relative to the mounting block 3. When the sliding rod 31 slides upwards, the stopper 33 located inside the mounting block 3 will squeeze the No. 3 spring 32. After being squeezed, the No. 3 spring 32 will undergo elastic deformation and contraction and store a certain amount of elastic potential energy. Then the medical staff can push the mounting seat 2. When the mounting seat 2 is pushed by the medical staff, it will slide inside the base 1. Wait for the mounting seat 2 to be After moving to the required distance, the medical staff can stop pushing the mounting seat 2, and then release the sliding rod 31. At this time, the No. 3 spring 32 in the elastic contraction state will rebound, so that the sliding rod 31 is clamped inside the waste limit hole 34 just below it. In addition, the medical staff can start the water pump 36, and the water pump 36 will pump out the water inside the water storage box 35. The water inside the water storage box 35 will flow along the hose 37 to the inside of the ball 28 and the stimulation block 29 and finally spray out from the corresponding holes opened in the stimulation block 29, thereby stimulating the patient's throat muscles to exercise his swallowing ability.

[0037] Working principle: If it is necessary to stimulate the swallowing muscles of the patient's throat, the mounting seat 2 can be inserted into the patient's mouth. During use, the patient's facial muscles will feel tired after opening his mouth for a long time. If it is necessary to support the patient's mouth to reduce the fatigue caused by opening the mouth for a long time, the medical staff can push the two sliding blocks 12 at the same time along the direction of the stimulation block 29. Because one side of the sliding block 12 coincides with one side of the serrated plate 18, and the two sliding blocks 12 are pushed. When the sliding blocks 12 are displaced in the vertical direction along the inclined surface of the serrated plate 18, the No. 1 spring 17 will undergo elastic deformation and stretching. Because a telescopic rod is provided inside the No. 1 spring 17, it can play a good synchronous limiting role on the two limit rods 16. By extending and retracting the telescopic rod inside the No. 1 spring 17, the sliding block 12 can push the connecting rod 13 through the support rod 14 during the movement. The connecting rod 13 will rotate after being pushed by the support rod 14. When the connecting rods 13 on both sides of the base 1 rotate, the distance between the two bite plates 15 will increase. After the two bite plates 15 are adjusted to the required angle position, the patient can bite the two bite plates 15 at the same time. After being bitten by the patient, the bite plates 15 will apply an extrusion force to the sliding block 12, and the direction of the extrusion force is from the tongue depressor 11 to the direction where the sliding block 12 is located. Under the action of the mutual engagement of the sliding block 12 and the serrated plate 18, the bite plate 15 can be limited to avoid the secondary rotation of the connecting rod 13. After the head is pressed, if it is necessary to stimulate different positions inside the patient's throat, the staff can press the paddle 27. After being pressed, the paddle 27 will drive the missing gear 23 to rotate. During the rotation of the missing gear 23, the No. 1 rotating block 21 or the No. 2 rotating block 22 will be driven to rotate. When the No. 1 rotating block 21 or the No. 2 rotating block 22 rotates, the ball 28 will be driven to rotate. When the No. 1 rotating block 21 rotates, the ball 28 will drive the stimulation block 29 to swing horizontally. When the No. 2 rotating block 22 rotates, the ball 28 will drive the stimulation block 29 to swing vertically. During the rotation of the missing gear 23, the outer wall of the missing gear 23 will squeeze the card block 24. After the card block 24 is squeezed, the No. 2 spring 25 will contract. When When the medical staff stops toggling the paddle 27, that is, the missing gear 23 stops rotating, the clamping block 24 will be re-connected to the groove of the missing gear 23 located directly in front of it under the action of the No. 2 spring 25, so that the stimulation block 29 can stimulate different positions inside the patient's throat, thereby improving the efficiency of rehabilitation training. If the medical staff needs to extend the stimulation block 29 inside the patient's mouth, the medical staff can first pull the sliding rod 31 upwards. After being pulled, the sliding rod 31 will slide relative to the mounting block 3. When the sliding rod 31 slides upwards, the stopper 33 located inside the mounting block 3 will squeeze the No. 3 spring 32. After being squeezed, the No. 3 spring 32 will undergo elastic deformation and contraction and store a certain amount of elastic potential energy. Then the medical staff can push the mounting seat 2.When the mounting seat 2 is pushed by the medical staff, it will slide inside the base 1. After the mounting seat 2 moves to the required distance, the medical staff can stop pushing the mounting seat 2 and then release the sliding rod 31. At this time, the No. 3 spring 32 in the elastic contraction state will rebound, so that the sliding rod 31 is clamped in the waste limit hole 34 directly below it. In addition, the medical staff can start the water pump 36, and the water pump 36 will pump out the water inside the water storage box 35. The water inside the water storage box 35 will flow along the hose 37 to the inside of the ball 28 and the stimulation block 29 and finally spray out from the corresponding holes opened at the stimulation block 29, thereby stimulating the patient's throat muscles to exercise his swallowing ability.
