Description

Technical Field

[0001] The invention relates to the technical field of swallowing training assistance, in particular to a swallowing function training auxiliary feeder for Parkinson's patients. Background Art

[0002] For Parkinson's patients, swallowing dysfunction is one of the common symptoms, often leading to aspiration, malnutrition and other complications. Dysphagia (medically known as "swallowing disorder") may be caused by Parkinson's disease, such as muscle stiffness, tremor, bradykinesia and other symptoms, affecting the muscles that control the mouth, throat and esophagus. In order to help improve swallowing function and reduce the risk of swallowing, auxiliary feeding devices have become a very effective auxiliary means. Assisted feeding devices can greatly alleviate Parkinson's patients' dysphagia, help them maintain adequate nutritional intake and reduce the risk of aspiration. Reasonable diet management and physical therapy can improve the patient's quality of life and delay the deterioration of swallowing function.

[0003] The patent with the announcement number CN218187305U discloses a device for taking medicine and feeding liquid food for critically ill patients, which belongs to the field of devices for taking medicine and feeding liquid food. The device for taking medicine and feeding liquid food for critically ill patients comprises an upper shell, one end of which is provided with a lower shell, one end of which is close to the upper shell and fixedly provided with a connecting clamp ring, the upper shell and the lower shell are connected by the connecting clamp ring, the other end of the upper shell is provided with an arc-shaped top cover, the top of which is provided with a nozzle, a catheter is sleeved on the nozzle, the catheter passes through the nozzle and extends to the interior of the upper shell, and the lower shell is far from the connecting clamp ring. A push rod is movably installed, and a push plate is installed at one end of the push rod. A through hole is opened in the center of the top of the arc-shaped top cover, and the hole wall of the through hole and the annular side wall of the nozzle are provided with matching threads A. It can achieve the effects of autonomous feeding and assisted feeding, and has dual functions. For patients who are more awake and have swallowing ability, the swallowing function of the patients can be practiced, which is helpful for later rehabilitation training. However, there is still a problem that the structure is complex, resulting in large volume and weight and cannot be worn. Therefore, an auxiliary feeder for swallowing function training of Parkinson's patients is proposed to solve the above-mentioned problems. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a swallowing function training auxiliary feeder for Parkinson's patients in view of the deficiencies in the above-mentioned prior art.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is: an auxiliary feeder for swallowing function training of Parkinson's patients, comprising a front bracket, a neck bracket is arranged at the rear end of the front bracket, a jaw bracket is hingedly connected to the rear end of the front bracket, a jaw bracket block is fixedly connected to the top end of the jaw bracket, a positioning structure is arranged below the front bracket, a training feeding structure is arranged on the front side of the front bracket, and difficulty adjustment structures are arranged on both sides of the neck bracket; The positioning structure includes an insert block, a buckle block is arranged on the outer side of the insert block, an upper folding piece and a lower folding piece are slidably connected inside the buckle block, a positioning groove is provided on the upper surface of the front bracket, and an inserting groove is provided on the side of the buckle block.

[0006] According to the above technical solution, a groove is provided on the bottom surface of the insert block, a buckle strip is fixedly connected to the bottom end of the lower folding piece, and a positioning block is fixedly connected to the top end of the upper folding piece.

[0007] When the user needs to wear the strap, the upper and lower jaws are pressed downward by the fingers to push the lower jaw downward, so that the lower jaw pulls the elastic force of the return spring downward, and the other end of the return spring holds the buckle block, and then the lower and lower jaws drive the connected buckle strip to slide downward along the buckle block, so that the buckle strip is separated from the plug-in block inserted in the plug-in groove. When the buckle strip is separated from the groove on the plug-in block, the neck strap connected to the plug-in block can be smoothly pulled out of the plug-in groove, and the wearing convenience is improved by the plug-in and engaging structure. At the same time, when it is necessary to adjust the position of the jaw support block to fit the user's lower jaw, the upper and lower jaws are lifted upward by the fingers, so that the upper and lower jaws drive the connected positioning block to move upward, so that the positioning block is separated from the engaging groove on the front bracket.

[0008] According to the above technical solution, the training feeding structure includes a connecting tube, an end of the connecting tube away from the jaw support block is fixedly connected to an inflatable airbag, a spring arc piece is fixedly connected between the under-jaw support and the front support, two airbag solid blocks are fixedly connected to the front side of the spring arc piece, and a rubber airbag is fixedly connected to the side of the airbag solid block away from the spring arc piece.

[0009] According to the above technical solution, the left side of the rubber airbag is fixedly connected to an air inlet port, the top of the rubber airbag is fixedly connected to an infusion tube, the middle bottom side of the infusion tube is fixedly connected to an air supply tube, the air inlet port and the inner wall of the air supply tube are fixedly connected to single-way leaflets, and the top of the infusion tube is fixedly connected to an esophagus.

[0010] According to the above technical scheme, the interior of the jaw support block is interconnected with the connecting tube, the jaw support block is interconnected with the interior of the expansion airbag, and the infusion tube extends from the top of the rubber airbag to the inside of the rubber airbag. When the patient wears it correctly, when using it, the jaw support block needs to be squeezed by the mandible when lowering the head, and the lower jaw fits the jaw support block, so that the jaw support block is compressed and squeezes the lower jaw bracket. The jaw support block will be deformed when compressed and discharge part of the internal air into the expansion airbag through the connected connecting tube, so that the air in the expansion airbag increases and then bulges and fits the neck, thereby improving the comfort during use. At the same time, after the lower jaw bracket is compressed, it deflects around the connection with the front bracket and squeezes the spring arc sheet to deform, so that the spring arc sheet is deformed and squeezes the rubber airbag through the connected airbag solid block to be compressed. One end of the infusion tube in the expansion airbag is externally connected to the liquid supply pipe, and the external pipeline is connected to the liquid supply pipe. It is slowly transported upward until it enters the infusion tube. Since the inflatable airbag is under pressure, the internal air will be compressed, and the air inside the inflatable airbag will enter the infusion tube in one direction along the one-way leaflet on the inner wall of the air delivery tube. After the air enters the infusion tube, part of the liquid in the infusion tube will be separated from the liquid in the external pipe by the discharged air, and part of the liquid will be squeezed by the air and transported to the patient's mouth through the esophagus, so as to exercise the throat muscles and assist in swallowing and feeding, thereby improving the training effect. At the same time, when the inflatable airbag is under pressure, the spring arc sheet will be deformed and bent under pressure and put pressure on the throat, so that the patient needs to use the throat muscle strength to swallow during the swallowing process, so as to achieve the effect of auxiliary training. Then the inflatable airbag recovers its shape and the outside air enters the inflatable airbag in one direction through the one-way leaflet in the air inlet port.

[0011] According to the above technical solution, the difficulty adjustment structure includes a solid tube end, a pressure gas cylinder is fixedly connected to the inner side of the solid tube end, two sliding bars are fixedly connected to the inner wall of the pressure gas cylinder, a pressure plug is slidably connected between the two sliding bars, and a threaded rod is threadedly connected at the center of the pressure plug.

[0012] According to the above technical solution, a knob is provided at the rear end of the fixed tube end, a pressure delivery tube is fixedly connected to the front end of the pressure cylinder, and a pressure reduction rod is fixedly connected to the top end of the pressure delivery tube.

[0013] According to the above technical solution, the threaded rod is rotatably connected to the pressure cylinder, the solid tube end is fixedly connected to the neck support, the knob is fixedly connected to the rear end of the threaded rod, the top end of the pressure reduction rod is hingedly connected to the under-jaw bracket, and the overall shape of the pressure reduction rod is arc-shaped.

[0014] According to the above technical solution, the bottom end of the pressure reduction rod is fixedly connected to the front bracket, and the pressure reduction rod is a retractable structure. As the patient's training time increases and the difficulty of training the throat muscles needs to be increased, the knob can be turned to drive the pressure plug to slide along the pressure cylinder. When the pressure cylinder slides along the sliding bar and squeezes the air inside the pressure cylinder to be discharged to the pressure reduction rod through the connected pressure pipe, the air in the pressure reduction rod increases, which will increase the resistance and difficulty of the pressure reduction rod to contract under the pressure of the submandibular bracket when it approaches the front bracket.

[0015] The present invention adopts the above technical solution to bring the following beneficial effects: 1. The swallowing function training auxiliary feeder for Parkinson's patients improves the convenience of wearing through the plug-in and snap-fit ​​structure. At the same time, the positioning block is separated from the fitting groove on the front bracket. At this time, the position of the jaw support block can be adjusted by pulling the front bracket and sliding along the connection of the buckle block. The structure can be adjusted to adapt to the mandibular sizes of different patients, thereby improving the adaptation range and use effect. The structure is simple, light and easy to wear.

[0016] 2. The swallowing function training auxiliary feeder for Parkinson's patients uses air to squeeze part of the liquid and deliver it to the patient's mouth through the esophagus, so as to exercise the throat muscles through swallowing and feeding to assist in training and improve the training effect. At the same time, the inflatable airbag restores its deformation and the outside air enters the inflatable airbag in one direction through the one-way leaflet in the air inlet port, and uses the spring arc sheet to apply pressure to the throat, thereby increasing the frequency of pressure on the throat muscles and coordinating with swallowing and feeding to improve the training and recovery effects.

[0017] 3. The swallowing function training auxiliary feeder for Parkinson's patients increases the difficulty of overall contraction of the pressure rod by increasing the internal gas of the pressure rod, thereby improving the effect of throat muscle training, improving swallowing ability, and increasing muscle toughness during swallowing.

When the buckle strip 59 disengages from the groove 57 on the plug-in block 51, the neck support 2 connected to the plug-in block 51 can be smoothly pulled out from the insertion groove 56, and the plug-in locking structure improves the convenience of wearing. At the same time, when it is necessary to adjust the position of the jaw support block 4 to fit the user's jaw, the upper folding piece 53 is lifted upward with the fingers, so that the upper folding piece 53 drives the connected positioning block 58 to move upward, and the positioning block 58 is disengaged from the fitting groove 55 on the front bracket 1. At this time, the position of the jaw support block 4 can be adjusted by pulling the front bracket 1 to slide along the connection with the buckle block 52. The structure can be adjusted to adapt to the jawbone sizes of different patients, thereby improving the adaptation range and usage effect.

[0022] The training feeding structure 6 includes a connecting tube 61, an end of the connecting tube 61 away from the jaw support block 4 is fixedly connected to an inflatable airbag 62, a spring arc piece 63 is fixedly connected between the jaw support 3 and the front support 1, two airbag solid blocks 64 are fixedly connected to the front side of the spring arc piece 63, a rubber airbag 65 is fixedly connected to the side of the airbag solid block 64 away from the spring arc piece 63, an air inlet port 66 is fixedly connected to the left side of the rubber airbag 65, a liquid infusion tube 67 is fixedly connected to the top of the rubber airbag 65, an air supply tube 68 is fixedly connected to the middle bottom side of the liquid infusion tube 67, and the inner walls of the air inlet port 66 and the air supply tube 68 are fixed. A single-pass leaflet 69 is fixedly connected, and the top of the infusion tube 67 is fixedly connected to the esophagus 610. The interior of the jaw support block 4 is interconnected with the connecting tube 61, and the jaw support block 4 is interconnected with the interior of the expansion airbag 62. The infusion tube 67 extends from the top of the rubber airbag 65 to the inside of the rubber airbag 65. The jaw support block 4 will be deformed when it is compressed and discharge part of the internal air into the expansion airbag 62 through the connected connecting tube 61, so that the air in the expansion airbag 62 increases and swells and fits the neck, improving the comfort during use. At the same time, the jaw support 3 is deflected around the connection with the front bracket 1 after being compressed and squeezes the spring arc sheet 63 to deform. After the spring arc piece 63 is deformed, the rubber airbag 65 is squeezed by the connected airbag solid block 64 to be compressed. One end of the infusion tube 67 in the inflatable airbag 62 is connected to the liquid supply pipe, and the external pipe is allowed to slowly transport upward until it enters the infusion tube 67. Since the inflatable airbag 62 is compressed, the internal air will be compressed, and the air inside the inflatable airbag 62 will enter the infusion tube 67 in one direction along the one-way leaflet 69 on the inner wall of the air supply pipe 68. After the air enters the infusion tube 67, part of the liquid in the infusion tube 67 will be separated from the liquid in the external pipe by the discharged air, and part of the liquid will be squeezed by the air through the esophagus 67. 10 is delivered to the patient's mouth so as to exercise the throat muscles through swallowing and feeding to assist the exercise and improve the training effect. At the same time, when the expansion airbag 62 is pressurized, the spring arc piece 63 will be compressed and deformed and apply pressure to the throat, so that the patient needs to use the throat muscle strength to swallow during the swallowing process to achieve the effect of auxiliary training. Then the expansion airbag 62 restores its deformation and the outside air enters the expansion airbag 62 in one direction through the one-way leaflet 69 in the air inlet port 66. The spring arc piece 63 is used to apply pressure to the throat, thereby increasing the frequency of throat muscle pressure and coordinating with swallowing and feeding to improve the training and recovery effects.

[0023] The difficulty adjustment structure 7 includes a fixed tube end 71, a pressure gas cylinder 72 is fixedly connected to the inner side of the fixed tube end 71, two sliding bars 73 are fixedly connected to the inner wall of the pressure gas cylinder 72, a pressure plug 74 is slidably connected between the two sliding bars 73, a threaded rod 75 is threadedly connected to the center of the pressure plug 74, a knob 76 is provided at the rear end of the fixed tube end 71, a pressure pipe 77 is fixedly connected to the front end of the pressure gas cylinder 72, a pressure reduction rod 78 is fixedly connected to the top end of the pressure pipe 77, the threaded rod 75 is rotatably connected to the pressure gas cylinder 72, the fixed tube end 71 is fixedly connected to the neck support 2, the knob 76 is fixedly connected to the rear end of the threaded rod 75, the top end of the pressure reduction rod 78 is hingedly connected to the jaw bracket 3, and the overall shape of the pressure reduction rod 78 is arc-shaped. The bottom end of the rod 78 is fixedly connected to the front bracket 1. The pressure reduction rod 78 is a retractable structure. By turning the knob 76, the knob 76 is rotated to drive the pressure plug 74 to slide along the pressure cylinder 72. When the pressure cylinder 72 slides along the sliding bar 73 and squeezes the air inside the pressure cylinder 72 to be discharged to the pressure reduction rod 78 through the connected pressure pipe 77, the air in the pressure reduction rod 78 increases. When the pressure reduction rod 78 is pressed against the front bracket 1 by the pressure of the submandibular bracket 3, the resistance and difficulty of the pressure reduction rod 78 to the compressed air increase. By increasing the internal gas of the pressure reduction rod 78 to increase the difficulty of the overall contraction of the pressure reduction rod 78, the effect of throat muscle training is improved, the swallowing ability is improved, and the toughness of the muscles during swallowing is increased.

[0024] Working principle: When the user needs to wear the device, he presses the lower folding piece 54 on the plug-in block 51 with his fingers, and presses the lower folding piece 54 downward, so that the lower folding piece 54 pulls the elastic force of the return spring downward, and the other end of the return spring pulls the buckle block 52, and then the lower folding piece 54 drives the connected buckle strip 59 to slide downward along the buckle block 52, so that the buckle strip 59 is separated from the plug-in block 51 inserted in the insertion groove 56. When the buckle strip 59 is separated from the groove 57 on the plug-in block 51, the neck support 2 connected to the plug-in block 51 can be smoothly removed from the insertion groove 56. The plug-in and snap-fit ​​structure improves the wearing convenience. At the same time, when it is necessary to adjust the position of the jaw support block 4 to fit the jaw of the user, the upper folding piece 53 is lifted upward by fingers, so that the upper folding piece 53 drives the connected positioning block 58 upward to move, so that the positioning block 58 is separated from the fitting groove 55 on the front bracket 1. At this time, the position of the jaw support block 4 can be adjusted by pulling the front bracket 1 to slide along the connection with the buckle block 52. The structure can be adjusted to adapt to the jawbone sizes of different patients, thereby improving the adaptation range and use effect. When the patient wears it correctly, when using it, the jaw support block 4 needs to be squeezed by the mandible when lowering the head, and the lower jaw fits the jaw support block 4, so that the jaw support block 4 is compressed and squeezes the lower jaw bracket 3. The jaw support block 4 is deformed when compressed and discharges part of the internal air into the expansion airbag 62 through the connected connecting pipe 61, so that the air in the expansion airbag 62 increases and swells and fits the neck, thereby improving the comfort during use. At the same time, the lower jaw bracket 3 is compressed and deflected around the connection with the front bracket 1 and squeezes the spring arc piece 63 to deform, so that the spring arc piece 63 is deformed and squeezes the rubber airbag 65 through the connected airbag solid block 64 to be compressed. One end of the infusion tube 67 in the expansion airbag 62 is externally connected to the liquid supply tube, and the external pipe is allowed to slowly transport upward until it enters the infusion tube 67. Since the expansion airbag 62 is compressed, the internal air is compressed, and the air inside the expansion airbag 62 flows along the inner wall of the air supply tube 68 The one-way leaflet 69 enters the infusion tube 67 in one direction. After the air enters the infusion tube 67, part of the liquid in the infusion tube 67 will be separated from the liquid in the external pipe by the discharged air, and part of the liquid will be squeezed by the air and delivered to the patient's mouth through the esophagus 610, so as to exercise the throat muscles and assist in swallowing and feeding to improve the training effect. At the same time, when the expansion airbag 62 is pressurized, the spring arc piece 63 will be deformed and bent by the pressure and apply pressure to the throat, so that the patient needs to use the throat muscle strength to swallow during the swallowing process to achieve the effect of auxiliary training. Then the expansion airbag 62 recovers its deformation and the outside air enters the expansion airbag 62 in one direction through the one-way leaflet 69 in the air inlet port 66. The spring arc piece 63 is used to apply pressure to the throat, thereby increasing the frequency of throat muscle pressure and cooperating with swallowing and feeding to improve the training and recovery effects. As the patient's training time increases and it is necessary to increase the difficulty of training the patient's throat muscles, the knob 76 can be turned to drive the pressure plug 74 to slide along the pressure cylinder 72. When the pressure cylinder 72 slides along the sliding bar 73 and squeezes the air inside the pressure cylinder 72 to be discharged to the pressure reduction rod 78 through the connected pressure pipe 77, the air in the pressure reduction rod 78 increases. When the pressure reduction rod 78 is pressed against the front bracket 1 by the pressure of the submandibular bracket 3, the resistance and difficulty of the pressure reduction rod 78 being contracted by the compressed air will increase. By increasing the gas inside the pressure reduction rod 78 to increase the difficulty of the overall contraction of the pressure reduction rod 78, the effect of throat muscle training is improved, the swallowing ability is improved, and the toughness of the muscles during swallowing is increased.

[0025] The present invention provides a swallowing function training auxiliary feeder for Parkinson's patients. There are many methods and ways to implement the technical solution. The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be considered as the protection scope of the present invention. All components not specified in this embodiment can be implemented by existing technologies.
