Description

Technical Field

[0001] This invention belongs to the field of rehabilitation training technology, specifically an oral swallowing function rehabilitation training aid. Background Technology

[0002] Dysphagia is a common complication in patients with stroke, traumatic brain injury, and neurodegenerative diseases, severely impacting their nutritional intake and quality of life. Currently, clinical rehabilitation often employs resistance training of the lip and tongue muscles, as well as sucking exercises, to strengthen the perioral muscles and improve the swallowing reflex.

[0003] Existing oral swallowing rehabilitation trainers mostly use a structure where an air bag connects to a mouthpiece. Patients exercise their oral muscles by sucking or inflating the mouthpiece. However, the mouthpiece, as a component that directly contacts the oral cavity, requires frequent disassembly, cleaning, or replacement to meet hygiene requirements. The connection between the mouthpiece and air bag in existing trainers is relatively simple, often using a direct connection or a threaded connection. Direct connections are prone to loosening and falling off during training due to pulling or pressure changes in the patient's mouth, leading to training interruptions. While threaded connections are secure, disassembly and assembly are laborious and time-consuming, which is not user-friendly for medical staff or patients with limited hand function.

[0004] Therefore, the present invention provides an oral swallowing function rehabilitation training aid. Summary of the Invention

[0005] To address the shortcomings of existing technologies and solve the problem mentioned in the background art, where the suction nozzle, as a component that directly contacts the oral cavity, requires frequent disassembly, cleaning, or replacement to meet hygiene requirements, the connection structure between the suction nozzle and the air bladder in existing training devices is relatively simple, often using direct sleeve or threaded connection. Direct sleeve connections are prone to loosening and falling off during training due to the pulling or pressure changes in the patient's oral cavity, leading to training interruptions; while threaded connections, although secure, are laborious and time-consuming to assemble and disassemble, which is not user-friendly for medical staff or patients with limited hand function. Therefore, this oral swallowing function rehabilitation training aid is proposed.

[0006] The technical solution adopted by this invention to solve its technical problem is as follows: The oral swallowing function rehabilitation training aid of this invention includes an air bladder, a suction cup, and a first connecting block; the top of the air bladder communicates with the first connecting block, the top of the first connecting block is movably connected to the suction cup, the inner wall of the first connecting block is provided with an insertion mechanism, and the top of the inner wall of the first connecting block is provided with a guide mechanism; the bottom of the insertion rod is provided with a communication mechanism, the bottom of the inner wall of the first connecting block is provided with a reset component, and a pressing mechanism is provided in the first groove opened on one side of the annular wedge. A guide assembly is provided on the side of the pressing mechanism near the annular wedge block. The insertion mechanism includes a positioning groove, a rod, and a limiting ring. Four sets of positioning grooves are provided, arranged in a ring on the top of the inner wall of the first connecting block. The rod is movably inserted into the inner wall of the first connecting block, and the top of the rod surface is fixedly installed with the limiting ring. The top of the rod communicates with the suction cup. The coordinated arrangement of the positioning groove, the rod, and the limiting ring ensures that after the suction cup is inserted into the first connecting block, the limiting ring can achieve axial limiting, preventing the suction cup from loosening and falling off during training, and ensuring a secure installation.

[0007] Preferably, the guiding mechanism includes annular wedges, fixed blocks, and a first groove. Four sets of annular wedges and fixed blocks are provided. The four sets of annular wedges are fixedly installed in a ring on the top of the inner wall of the first connecting block. The four sets of fixed blocks are fixedly installed in a ring on the side of the insertion rod surface near the positioning groove. The fixed blocks are movably inserted into the inner wall of the first connecting block through the opening of the positioning groove and are slidably connected to the four sets of annular wedges. A first groove is provided on one side of the bottom of the annular wedge, and the fixed blocks are movably engaged in the first groove. In this design, the cooperative arrangement of the annular wedges, fixed blocks, and the first groove allows the fixed blocks to automatically guide along the inclined surface of the annular wedges and engage in the first groove when the insertion rod is inserted. This not only quickly completes the alignment but also prevents the suction cup from rotating circumferentially.

[0008] Preferably, the communication mechanism includes an air supply pipe, a conical insert, and a sealing ring. The air supply pipe is connected to the bottom of the insert rod, and the bottom of the air supply pipe is connected to the conical insert. The sealing ring is fixedly installed at the bottom of the inner wall of the first connecting block. The top of the sealing ring has a conical groove identical to that of the conical insert. The conical insert is movably inserted into the inner wall of the sealing ring and can expand the sealing ring after insertion to achieve a seal. In this scheme, the coordinated arrangement of the air supply pipe, the conical insert, and the sealing ring allows the conical insert to expand when inserted into the sealing ring to achieve an interference seal, forming a reliable air passage between the airbag and the suction cup, avoiding gas leakage during training, and ensuring constant resistance.

[0009] Preferably, the reset assembly includes a spring and a push ring. The spring is fixedly installed at the bottom of the inner wall of the first connecting block, and the top of the spring is fixedly installed with the push ring. The top of the push ring is slidably connected with the fixed small block. In this scheme, the cooperation between the spring and the push ring allows the spring to provide an upward auxiliary push force to the insertion rod through the push ring when the fixed small block is dislodged from the first groove, thereby realizing the rapid ejection of the suction cup and making disassembly easier.

[0010] Preferably, the pressing mechanism includes a wedge, a fixed long rod, and a connecting ring. The wedge is slidably connected in a first groove on one side of the annular wedge. The side of the wedge near the first connecting block is fixedly connected to the fixed long rod. A rectangular groove is provided on the surface of the first connecting block near the fixed long rod for the fixed long rod to move up and down. The side of the fixed long rod away from the wedge is fixedly installed to the connecting ring. In this design, the wedge, fixed long rod, and connecting ring are designed so that the operator only needs to press down on the connecting ring to push the fixed small block out of the first groove through the wedge, thus releasing the jamming. The disassembly operation can be completed with one hand, making it convenient to use.

[0011] Preferably, the guide component includes a second groove and a second connecting block. The second groove is formed in a first groove on one side of the annular wedge. The second connecting block is fixedly installed on the side of the wedge close to the annular wedge. The second connecting block is slidably connected to the inner wall of the annular wedge through the second groove. In this design, the cooperation between the second groove and the second connecting block allows the wedge to slide smoothly along the second groove during the pressing process, ensuring smooth and accurate disassembly and avoiding jamming.

[0012] The beneficial effects of this invention are as follows: 1. The oral swallowing function rehabilitation training aid of the present invention, through the setting of positioning groove, insertion rod, limiting ring, annular wedge, fixing block and first groove, the positioning groove, insertion rod and limiting ring are set in a cooperative manner so that after the suction cup is inserted into the first connecting block, the limiting ring can achieve axial limiting, preventing the suction cup from loosening and falling off during training, and ensuring firm installation. The cooperative setting of annular wedge, fixing block and first groove allows the fixing block to be automatically guided along the inclined surface of annular wedge and locked into the first groove when the insertion rod is inserted, which can quickly complete the alignment and prevent the suction cup from rotating circumferentially.

[0013] 2. The oral swallowing function rehabilitation training aid described in this invention, through the arrangement of the air supply tube, the conical insert, the sealing ring, the spring, and the push ring, allows the air supply tube, the conical insert, and the sealing ring to cooperate in such a way that when the conical insert is inserted into the sealing ring, it can expand to achieve an interference seal, forming a reliable air passage between the airbag and the suction cup, avoiding gas leakage during training, and ensuring constant resistance. The cooperation between the spring and the push ring allows the spring to provide an upward auxiliary push to the insert rod through the push ring when the fixed small block is dislodged from the first groove, realizing the rapid ejection of the suction cup and making disassembly effortless.

The top of the insertion rod 32 is connected to the suction cup 11. The guide mechanism 4 includes annular wedges 41, fixing blocks 42, and a first groove 43. There are four sets of annular wedges 41 and fixing blocks 42. The four sets of annular wedges 41 are fixedly installed in annular shape on the top of the inner wall of the first connecting block 2. The four sets of fixing blocks 42 are fixedly installed in annular shape on the side of the insertion rod 32 near the positioning groove 31. The fixing blocks 42 are movably inserted into the inner wall of the first connecting block 2 through the opening of the positioning groove 31 and are slidably connected with the four sets of annular wedges 41. The first groove 43 is opened on one side of the bottom of the annular wedges 41. The fixed small block 42 is movably engaged in the first groove 43. The connecting mechanism 5 includes an air supply pipe 51, a conical insert 52, and a sealing ring 53. The air supply pipe 51 is connected to the bottom of the insert rod 32, and the bottom of the air supply pipe 51 is connected to the conical insert 52. The sealing ring 53 is fixedly installed at the bottom of the inner wall of the first connecting block 2. The top of the sealing ring 53 has a conical groove identical to that of the conical insert 52. The conical insert 52 is movably inserted into the inner wall of the sealing ring 53 and can open the sealing ring 53 after insertion to achieve a seal. The reset assembly 6 includes a spring 61 and a push ring 62. The spring 61 is fixedly installed at the bottom of the inner wall of the first connecting block 2, and the top of the spring 61 is fixedly installed with the push ring 62. The top of the push ring 62 is slidably connected to the fixed small block 42. The pressing mechanism 7 includes a wedge. The guide assembly 8 includes a wedge 71, a fixed long rod 72, and a connecting ring 73. The wedge 71 is slidably connected in the first groove 43 opened on one side of the annular wedge 41.

The side of the fixed long rod 72 away from the wedge 71 is fixedly installed with the connecting ring 73. The guide assembly 8 includes a second groove 81 and a second connecting block 82. The second groove 81 is opened in the first groove 43 opened on one side of the annular wedge 41. The second connecting block 82 is fixedly installed on the side of the wedge 71 near the annular wedge 41. The second connecting block 82 is slidably connected to the inner wall of the annular wedge 41 through the opening of the second groove 81.

[0020] like Figures 1 to 7 As shown, the combination of the airbag 1 and the suction cup 11 allows the patient to perform sucking or inflatable resistance training by holding the suction cup 11 in their mouth, effectively exercising the perioral muscles and promoting the recovery of swallowing function. The first connecting block 2... The configuration provides a stable assembly carrier for the insertion mechanism 3, guide mechanism 4, and reset assembly 6, ensuring the reliability of the collaborative work of each mechanism and the compact overall structure. The matching arrangement of the positioning groove 31, the insertion rod 32, and the limiting ring 33 allows the limiting ring 33 to achieve axial limiting after the suction cup 11 is inserted into the first connecting block 2, preventing the suction cup 11 from loosening and falling off during training, ensuring a firm installation. The matching arrangement of the annular wedge block 41, the fixing block 42, and the first groove 43 allows the fixing block 42 to automatically guide along the inclined surface of the annular wedge block 41 and lock into the first groove 43 when the insertion rod 32 is inserted, which can quickly complete the alignment and prevent the suction cup 11 from rotating circumferentially. The matching arrangement of the air supply pipe 51, the conical insert 52, and the sealing ring 53 allows the conical insert 52 to be opened when inserted into the sealing ring 53 to achieve the desired effect. The airtight seal ensures a reliable air passage between the airbag 1 and the suction cup 11, preventing gas leakage during training and ensuring constant resistance. The combination of spring 61 and push ring 62 allows spring 61 to provide upward auxiliary force to the insertion rod 32 via push ring 62 when the fixed block 42 is dislodged from the first groove 43, enabling the suction cup 11 to pop out quickly and effortlessly. The combination of wedge block 71, fixed rod 72, and connecting ring 73 allows the operator to simply press down on the connecting ring 73 to push the fixed block 42 out of the first groove 43 via wedge block 71, releasing the jamming. The disassembly operation can be completed with one hand, making it convenient to use. The combination of second groove 81 and second connecting block 82 allows wedge block 71 to slide smoothly along second groove 81 during the pressing process, ensuring smooth and accurate disassembly and avoiding jamming.

[0021] Working principle: During operation, when it is necessary to connect the suction cup 11 to the airbag 1, the operator holds the suction cup 11 and inserts the rod 32 into the inner wall of the first connecting block 2. During the insertion process, the fixing block 42, which is fixedly installed on the surface of the rod 32, first aligns with the positioning groove 31 at the top of the inner wall of the first connecting block 2 and slides along the inclined surface of the annular wedge 41. As the rod 32 continues to be inserted, the fixing block 42 slides into the first groove 43 along the surface of the annular wedge 41, realizing a movable engagement. At this time, the limiting ring 33 abuts against the top of the first connecting block 2, completing the axial limiting of the suction cup 11, making it firmly installed and not easy to fall off. At the same time, the conical insert 52 at the bottom of the rod 32 is inserted into the conical groove of the sealing ring 53. During the insertion process, the conical insert 52 expands the sealing ring 53 to achieve interference fit. The airbag 1 is sealed so that the gas inside can reliably communicate with the suction cup 11 through the air supply pipe 51 and the insertion rod 32, ensuring airtightness during training. When the suction cup 11 needs to be disassembled for cleaning or replacement, the operator presses down on the connecting ring 73. The connecting ring 73 drives the wedge block 71 to move downward in the first groove 43 along the direction of the second groove 81 through the fixed long rod 72. The downward movement of the wedge block 71 pushes the fixed small block 42, which is stuck in the first groove 43, downward, so that the fixed small block 42 is freed from the locking constraint of the first groove 43. At this time, under the elastic force of the spring 61 in the reset assembly 6, the push ring 62 pushes the fixed small block 42 upward, and the auxiliary insertion rod 32 pops up as a whole, thereby realizing the rapid separation of the suction cup 11 from the first connecting block 2. The disassembly operation is labor-saving and convenient.
