Description

Technical Field

[0001] This invention belongs to the field of swallowing disorder rehabilitation technology, specifically referring to a cold stimulation device for swallowing disorder rehabilitation. Background Technology

[0002] Dysphagia is a common and serious complication after stroke, neurodegenerative diseases, and head and neck tumor surgery. Rehabilitation is crucial for preventing aspiration pneumonia and malnutrition. Cold stimulation therapy is a commonly used clinical method for swallowing function rehabilitation. It involves repeatedly and gently stimulating the base of the tongue and pharyngeal region with cold instruments to induce a swallowing reflex and promote neuromuscular function reconstruction.

[0003] Current cold stimulation therapy lacks an effective detection and response mechanism to determine whether swallowing is successfully induced. When the device is placed in the mouth and a stable environment is maintained, it stimulates the sensitive tongue base and pharynx. In addition to the swallowing reflex, patients may feel nauseous and then exhale rapidly or gag through the mouth. Secretions or the cold stimulation itself may trigger coughing. The exhalation phase of coughing requires a strong airflow to rush out of the mouth. How can we ensure the patient's respiratory safety and prevent the risk of suffocation caused by the enclosed space? Summary of the Invention

[0004] In response to the above situation and to overcome the shortcomings of the prior art, this invention provides a cold stimulation device for the rehabilitation of swallowing disorders. This application utilizes biting action to automatically trigger oral cavity sealing, and can accurately detect swallowing action based on oral negative pressure. When an effective swallowing action is detected, the stimulation can be automatically paused through a delayed start switch, and the next round of training can be automatically started after rest, ensuring that the timing and rhythm of each stimulation are in line with the physiological response. This solves the technical problem of effective detection and response mechanism for whether swallowing action has been successfully induced in the prior art. While forming a closed oral cavity space, normal exhalation can also be achieved, solving the technical problem of preventing the risk of suffocation caused by the closed space.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention proposes a cold stimulation device for the rehabilitation of swallowing disorders, comprising a support column, a reciprocating electric telescopic rod coaxially fixedly connected to one end of the support column, a semiconductor cooling touch head fixedly connected to the telescopic end of the reciprocating electric telescopic rod, an occlusal seat fixedly connected to the support column, occlusal airbags symmetrically fixedly connected to the occlusal seat, the occlusal airbags communicating with the support column, a sealing plate slidably connected to the outer circumferential wall of the support column, and a detection tube fixedly connected to the occlusal seat, one end of the detection tube slidably penetrating the sealing plate.

[0006] Preferably, a sealing ring is coaxially fixedly connected to one side of the inner circumferential wall of the detection tube, and a guide rod is coaxially fixedly connected inside the detection tube. A moving plate and a movable plate are slidably connected to the guide rod. The outer circumferential wall of the moving plate is fitted with the inner circumferential wall of the sealing ring. A first spring and a second spring are sleeved on the guide rod. The two ends of the first spring are fixedly connected to the side wall of the moving plate and one end of the sealing ring, respectively. The two ends of the second spring are fixedly connected to the side wall of the movable plate and the other side wall of the moving plate, respectively. The first spring and the second spring are initially in an uncompressed state. The first spring and the second spring drive the moving plate to be located in the middle of the sealing ring. A delayed start switch is fixedly connected to the inner circumferential wall of the sealing ring. The delayed start switch is electrically connected to the reciprocating electric telescopic rod and the semiconductor cooling touch head.

[0007] Preferably, the support column is provided with a connecting groove and a guide groove. One end of the connecting groove is connected to the hollow part of the bite airbag, and one end of the guide groove is connected to the other end of the connecting groove. A push rod is slidably connected in the guide groove. One end of the push rod extends out of the support column in a sliding seal and is fixedly connected to the sealing plate. A push spring is provided in the guide groove. Both ends of the push spring are fixedly connected to one end of the guide groove and the other end of the push rod, respectively.

[0008] The beneficial effects achieved by the present invention using the above structure are as follows: 1. It automatically triggers oral cavity sealing by biting action and can accurately detect swallowing action based on oral negative pressure. When an effective swallowing action is detected, it can automatically pause stimulation through a delayed start switch and automatically start the next round of training after rest. This ensures that the timing and rhythm of each stimulation are in line with physiological response. It can achieve normal exhalation while forming a closed oral cavity space, ensuring breathing safety. 2. The occlusal airbag drives the movement of the sealing plate, which works in conjunction with the occlusal seat to seal the oral cavity, simulating the oral environment during swallowing, which helps with swallowing rehabilitation training; 3. It uses the characteristic physiological negative pressure generated by swallowing itself as a detection signal and sets the trigger threshold through mechanical structure. It has strong anti-interference ability and accurate and reliable detection results. It effectively avoids false triggering caused by minor movements or breathing. It also realizes a complete automated rehabilitation cycle of cyclic stimulation. It can detect the completion of swallowing movements in real time and can also cycle through the stimulation and cessation of swallowing. 4. When the patient feels nauseous and exhales rapidly through the mouth or gags, the moving plate moves until its edge disengages from the inner wall of the sealing ring. The exhaust channel of the detection tube is opened, and the exhaled air can be quickly discharged out of the device through this gap. The pressure in the oral cavity is released accordingly, prioritizing the patient's respiratory safety. When exhalation ends, the second spring resets, pushing the movable plate and the moving plate back to their original positions, resealing the detection tube, and ensuring that the closed environment required for treatment is restored.

[0013] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0014] Example 1, as Figures 1-5As shown, the proposed solution provides a cold stimulation device for the rehabilitation of swallowing disorders, comprising a support column 1. A reciprocating electric telescopic rod 6 is coaxially fixedly connected to one end of the support column 1. A semiconductor cooling touch head 7 is fixedly connected to the telescopic end of the reciprocating electric telescopic rod 6. The semiconductor cooling touch head 7 is spherically shaped and contains a semiconductor cooling chip. An occlusal seat 3 is fixedly connected to the support column 1. The occlusal seat 3 conforms to the shape of the gums. Occlusal airbags 4 are symmetrically fixedly connected to the occlusal seat 3 and communicate with the support column 1. A sealing plate 2 is slidably connected to the outer circumferential wall of the support column 1. The sealing plate 2 conforms to the shape of the mouth. A detection tube 5 is fixedly connected to the occlusal seat 3. One end of the detection tube 5 can slide through the sealing plate 2.

[0015] like Figures 1-4 As shown, a sealing ring 51 is coaxially fixedly connected to one side of the inner circumferential wall of the detection tube 5. A guide rod 52 is coaxially fixedly connected inside the detection tube 5. A moving plate 53 and a movable plate 57 are slidably connected to the guide rod 52. The outer circumferential wall of the moving plate 53 is fitted with the inner circumferential wall of the sealing ring 51. The moving plate 53 is made of medical-grade PEEK material with high rigidity, light weight, and low coefficient of friction. A first spring 55 and a second spring 56 are sleeved on the guide rod 52. The two ends of the first spring 55 are fixedly connected to the side wall of the moving plate 53 and one end of the sealing ring 51, respectively. The two ends of the second spring 56 are fixedly connected to the side wall of the movable plate 57 and the other side wall of the moving plate 53, respectively. The first spring 55 and the second spring 56 are initially in an uncompressed state. The first spring 55 and the second spring 56 drive the moving plate 53 to be located in the middle of the sealing ring 51. The moving plate 53 moves with the change of oral pressure. When swallowing, negative pressure is generated in the oral cavity, and the moving plate 53 is close to one end of the sealing ring 51. When exhaling, the moving plate 53 moves away from the sealing ring 51. A time-delay start switch 54 is fixedly connected to the inner circumferential wall of the sealing ring 51. The time-delay start switch 54 is a touch switch. The time-delay start switch 54 is electrically connected to the reciprocating electric telescopic rod 6 and the semiconductor cooling touch head 7. When the moving plate 53 contacts the time-delay start switch 54, the reciprocating electric telescopic rod 6 and the semiconductor cooling touch head 7 stop. When the moving plate 53 moves away from the time-delay start switch 54, the reciprocating electric telescopic rod 6 and the semiconductor cooling touch head 7 start after a delay.

[0016] like Figures 1-3 and Figure 5As shown, the support column 1 is provided with a connecting groove 11 and a guide groove 12. One end of the connecting groove 11 is connected to the hollow part of the bite airbag 4, and one end of the guide groove 12 is connected to the other end of the connecting groove 11. A push rod 13 is slidably connected in the guide groove 12. One end of the push rod 13 extends out of the support column 1 in a slid seal and is fixedly connected to the sealing plate 2. A push spring 14 is provided in the guide groove 12. The two ends of the push spring 14 are fixedly connected to one end of the guide groove 12 and the other end of the push rod 13, respectively.

[0017] In practical use, the occlusal seat 3 is first placed in the oral cavity between the gums. The lips are closed and wrapped around the support post 1. Then, the teeth bite the occlusal seat 3 through the occlusal air bladder 4, compressing the occlusal air bladder 4. The air in the occlusal air bladder 4 enters the guide groove 12 through the connecting groove 11. The air pressure in the guide groove 12 increases, and the air pressure drives the push rod 13 to move in the guide groove 12, stretching the push spring 14. The push rod 13 drives the sealing plate 2 to move, and the sealing plate 2 contacts the lips. The sealing plate 2 and the occlusal seat 3 lock the lips, so that a closed space is formed in the oral cavity. When the blocking plate 2 contacts the lips, the manually controlled reciprocating electric telescopic rod 6 and the semiconductor cooling touch head 7 are activated. The reciprocating electric telescopic rod 6 drives the semiconductor cooling touch head 7 to gently and repeatedly stimulate the midline of the tongue root, stimulating the patient to swallow. When swallowing occurs, the tongue root pushes back and the pharyngeal constrictor muscles contract, compressing the oropharyngeal space. This compression of the oropharyngeal space creates a negative pressure in the oral cavity towards the throat. This negative pressure attracts the moving plate 53 inside the detection tube 5, bringing it closer to the blocking ring 51 and compressing the first spring 55. The moving plate 53 moves the movable plate 57 via the second spring 56. When the moving plate 53 contacts the delayed start switch 54, the reciprocating electric telescopic rod 6 and the semiconductor cooling touch head 7 stop. After swallowing, the pressure in the oral cavity returns to balance, the first spring 55 resets, and the first spring 55 drives the moving plate 53 to reset. The moving plate 53 stops contacting the delayed start switch 54, and the reciprocating electric telescopic rod 6 and the semiconductor cooling touch head 7 start after a delay, giving the patient a rest time. The reciprocating electric telescopic rod 6 and the semiconductor cooling touch head 7 provide cyclic stimulation. When the semiconductor cooling touch head 7 stimulates the sensitive base of the tongue and pharynx, the patient may feel nauseous and exhale rapidly or gag through the mouth. The lips are sealed by the sealing plate 2, and gas enters the detection tube 5, causing the moving plate 53 to move closer to the movable plate 57, stretching the first spring 55 and compressing the second spring 56. The moving plate 53 moves away from the sealing ring 51. When the moving plate 53 moves to the point where it is no longer in contact with the inner wall of the sealing ring 51, the exhaust channel of the detection tube 5 is opened, and gas is discharged from the mouth through the detection tube 5. After the gas is discharged, the second spring 56 returns to its original position, causing the moving plate 53 to return to its original position. The moving plate 53 cooperates with the sealing ring 51 to reseal the detection tube 5. When the cold stimulation stops, the reciprocating electric telescopic rod 6 and the semiconductor cooling touch head 7 are turned off, the teeth stop contacting the occlusal airbag 4, the occlusal airbag 4 is reset, the air in the connecting groove 11 and the guide groove 12 enters the occlusal airbag 4, pushing the spring 14 to reset, driving the push rod 13 and the sealing plate 2 to reset, and holding the support column 1 to remove the occlusal seat 3 from the mouth.

[0018] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
