Abstract
Description
Technical Field
[0001] This invention relates to the field of cleaning devices, and in particular to a tongue-biting cleaning device to prevent epileptic seizures. Background Technology
[0002] Epilepsy is a chronic neurological disorder characterized by abnormal synchronous discharges of neurons in the brain, leading to transient brain dysfunction. Studies indicate that there are approximately nine million epilepsy patients in my country, with over five million cases of active epilepsy and nearly four hundred thousand new cases each year. Notably, some patients do not respond well to anti-epileptic drugs, forming a group of patients with drug-resistant epilepsy. During an acute epileptic seizure, generalized or localized tonic-clonic contractions often cause involuntary biting, which can easily lead to tongue injury and even severe bleeding. Significant tongue trauma can directly threaten the patient's life.
[0003] Currently, routine care for preventing tongue biting during epileptic seizures primarily relies on manual intervention. Caregivers or family members typically need to forcibly pry open the patient's mouth and then insert gauze, towels, or other substitutes to prevent direct biting of the tongue by the upper and lower teeth. However, this emergency treatment method has significant clinical limitations. On the one hand, the packing material may obstruct the oral airway, affecting the patient's normal ventilation and increasing the risk of suffocation. On the other hand, patients often experience increased respiratory secretions during seizures, and sputum in the mouth can easily accumulate and be compressed by the packing material, further obstructing the airway and even inducing aspiration pneumonia. Furthermore, manual operation is not only time-consuming and laborious but may also cause finger injuries to the rescuer if the patient's convulsions are strong. Therefore, there is an urgent need to optimize the structure and function of existing tongue-biting prevention and oral cleaning devices to address the aforementioned problems of inconvenience, ventilation obstruction, and secretion blockage. Summary of the Invention
[0004] The present invention aims to provide a tongue-cleaning device to prevent epileptic seizures, which solves the problems of inconvenient operation, ventilation obstruction and secretion blockage caused by manual intervention.
[0005] To achieve the above objectives, the technical solution of the present invention is as follows: A tongue-biting prevention device for epileptic seizures, comprising:
[0006] Sleeve;
[0007] A fixing cylinder, which passes through the opening of the sleeve;
[0008] Two flexible pads are symmetrically arranged on both sides of the sleeve and are movably connected to the outer wall of the sleeve. Each flexible pad has a groove in the middle and one end of the two flexible pads can abut against each other.
[0009] Two flexible rods are rotatably connected between the flexible pad and the slide groove, and the two flexible rods are symmetrically arranged.
[0010] A positioning block, wherein a through hole is provided in the center for the sleeve to pass through, and the positioning block is slidably connected to the sleeve through the through hole;
[0011] Two push rods, both of which are rotatably connected between the flexible pad and the positioning block;
[0012] An oral cavity cleaning component is disposed inside a fixed cylinder and uses negative pressure to suction out secretions from the oral cavity.
[0013] Furthermore, the oral cleaning component includes:
[0014] A micro motor, wherein the micro motor is disposed inside a sleeve;
[0015] A rotating tube, which passes through the center of the fixed cylinder and is rotatably connected to the fixed cylinder;
[0016] A negative pressure fan, wherein the center of the negative pressure fan is coaxially connected to a micro motor, and the negative pressure fan is disposed inside a rotating tube;
[0017] A flexible hose, which is connected to the end of a rotating tube.
[0018] Using the above technical solution, a micro motor can drive a negative pressure fan to rotate, thereby clearing secretions from the mouth through a soft tube.
[0019] Furthermore, the negative pressure fan and the rotating tube are fitted with an interference fit.
[0020] By adopting the above technical solution, the interference fit can drive the rotating tube and the flexible tube to rotate together, so that the flexible tube can generate suction in different directions, which is beneficial to improve the efficiency and effect of cleaning oral secretions.
[0021] Furthermore, the sleeve is provided with multiple equidistant limiting holes, and the positioning block is provided with limiting pins that cooperate with the limiting holes.
[0022] Furthermore, a compression spring is connected between the limiting pin and the positioning block.
[0023] The above technical solution utilizes the cooperation of the limiting pin and the limiting hole to limit the positioning block, while the compression spring ensures the reliability of the positioning block's limitation. Furthermore, it can be flexibly adjusted and reliably fixed according to the size of the patient's oral cavity, adapting to the usage needs of different individuals.
[0024] Furthermore, each of the flexible plates has multiple protrusions on its surface, and all of the protrusions are at a certain distance from the end of the flexible pad.
[0025] The above technical solution utilizes the protrusions to facilitate a more stable bite on the flexible pad for epilepsy patients.
[0026] Furthermore, a collection bottle is threadedly connected to one side of the sleeve.
[0027] By using the above technical solution, the secretions can be collected and temporarily stored using collection bottles, which helps to maintain the continuity of cleaning work.
[0028] Furthermore, a collection pipe located outside the fixed cylinder is connected to the rotating tube, and a one-way valve is installed on the collection pipe.
[0029] By adopting the above technical solution, the one-way valve facilitates the flow of secretions from the rotating tube into the sleeve, thus avoiding the problem of secretion backflow.
[0030] Furthermore, the sleeve is also provided with a guide ring, the inner side of which is a conical surface. One end of the guide ring is located on one side of the collection tube, and the other end is close to the connection between the collection bottle and the sleeve.
[0031] Using the above technical solution, the inner wall of the guide ring facilitates the flow of secretions to the collection bottle. At the same time, due to the continuous negative pressure inhalation, the gas flow can be guided to the inner wall of the guide ring, further propelling the secretions to the collection bottle.
[0032] Furthermore, the ends of the flexible pad are designed with rounded corners.
[0033] By adopting the above technical solution, after the flexible pad is rolled up by the flexible rod, the rounded corners can prevent the end of the flexible pad from damaging the inner wall of the oral cavity, thus improving the safety of this solution.
[0034] Compared with existing technologies, the beneficial effects of this solution are:
[0035] 1. This solution can replace the emergency treatment method of manually prying open the mouth and stuffing gauze or towels in, significantly improving the convenience and safety of on-site rescue operations during epileptic seizures. In use, the ends of the two flexible pads are positioned using a positioning block and a push rod to form a triangular bevel, facilitating the rapid insertion of the device into the patient's mouth. This avoids direct contact between the rescuer's hands and the patient's mouth, effectively reducing the risk of the rescuer being bitten during convulsions. Once the device is inside the mouth, the flexible rod moves the push rod and the flexible pads. When the two flexible pads are parallel, the ends of the pads inside the mouth will lift due to the deformation of the flexible rod, allowing the device to keep the mouth open. Simultaneously, the raised surface and rounded ends of the flexible pads enhance the stability of the bite and reduce mechanical damage to the oral mucosa and tongue.
[0036] 2. In this approach, the supportive effect of the flexible pad maintains a moderate separation between the upper and lower teeth, creating an open space and avoiding airway obstruction caused by traditional fillings that may compress the tongue root or soft palate. Since this approach does not require fillings, it does not occupy central oral space, allowing the patient to maintain spontaneous breathing and gas exchange, thereby reducing the risk of secondary injury due to suffocation.
[0037] 3. This solution not only maintains airway patency but also clears oral secretions. The specific process is as follows: a micro-motor drives a negative pressure fan to rotate, generating continuous negative pressure within the rotating tube and flexible tube. This actively suctions out sputum and secretions from the oral cavity and guides them into a collection bottle through the rotating tube, collection tube, and one-way valve. The flexible tube's rotation with the rotating tube allows for adjustable suction direction and a wider cleaning range. The conical structure of the guide ring further utilizes airflow to guide secretions into the collection bottle, while the negative pressure fan also helps expel warm, moist air from the oral cavity, improving the oral ventilation environment.

Detailed Implementation
[0046] The present invention will be further described in detail below through specific embodiments:
[0047] Example
[0048] like Figures 1 to 7 As shown, a tongue-biting prevention device for epileptic seizures includes:
[0049] The sleeve 1 has anti-slip textured edges on its right side for easy gripping by rescuers. Multiple equidistant limiting holes 2 are located on the upper surface of the sleeve 1 along its length. These limiting holes 2 are blind holes and do not penetrate the sidewall of the sleeve 1, preventing secretions from being ejected through them.
[0050] The fixed sleeve 3 is inserted through the opening of the sleeve 1 and is threadedly connected to the opening of the fixed sleeve 3.
[0051] Two flexible pads 4 are symmetrically arranged on the upper and lower sides of the sleeve 1, and each flexible pad 4 is movably connected to the outer wall of the sleeve 1. The end of each flexible pad 4 away from the sleeve 1 is rounded to prevent damage to the oral cavity wall of the epilepsy patient if the end of the flexible pad 4 is raised. A groove 5 is provided in the middle of each flexible pad 4, and the ends of the two flexible pads 4 away from the sleeve 1 can abut against each other, so that the left ends of the two flexible pads 4 can be closed to form a triangular structure. In this embodiment, the surface of each flexible plate is provided with multiple protrusions 6. All the protrusions 6 are at a certain distance from the end of the flexible pad 4, and the protrusions 6 are irregularly distributed, which is beneficial to the occlusal positioning of the teeth.
[0052] Two flexible rods 7 are rotatably connected between the flexible pad 4 and the slide groove 5 via pins 8. The left side of the sleeve 1 is provided with a groove 13 for placing the pins 8 and the ends of the flexible rods 7. The two flexible rods 7 are arranged symmetrically up and down.
[0053] The positioning block 9 has a through hole at its center for the sleeve 1 to pass through, and the positioning block 9 is slidably connected to the sleeve 1 through the through hole. The upper center of the positioning block 9 has a through hole, and a limiting pin 10 that mates with the limiting hole 2 passes through the through hole. The limiting pin 10 is a cone, and a compression spring 11 connects the limiting pin 10 and the positioning block 9. The compression spring 11 helps the limiting pin 10 maintain the stability of its insertion into the limiting hole 2.
[0054] Two push rods 12 are rotatably connected between the flexible pad 4 and the positioning block 9 via pins 8. Corresponding grooves 13 are provided on the flexible pad 4 and the positioning block 9 for placing the push rods 12 and the pins 8.
[0055] An oral cavity cleaning component is disposed within a fixed cylinder 3 and uses negative pressure to suction out secretions from the oral cavity. In this embodiment, the oral cavity cleaning component includes:
[0056] The micro motor 14 is threadedly connected to the right side of the sleeve 1. The right side of the sleeve 1 has a mounting hole for installing the micro motor 14. In this embodiment, the micro motor 14 is a waterproof motor, which facilitates the cleaning and disinfection of the device.
[0057] A rotating tube 15 is inserted through the center of the fixed cylinder 3 and rotatably connected to it. One side of the rotating tube is located outside the fixed cylinder 3. In this embodiment, multiple collection tubes 16 located outside the fixed cylinder 3 are connected to the rotating tube 15. The multiple collection tubes 16 are arrayed on the rotating tube 15, and each collection tube 16 is equipped with a one-way valve 17. The one-way valve 17 allows the secretions in the rotating tube 15 to enter the sleeve 1 in one direction.
[0058] A negative pressure fan is coaxially connected to the center of the micro motor 14 and is disposed inside the rotating tube 15. In this embodiment, the negative pressure fan consists of an outer ring 18, an inner ring 19, and three negative pressure blades 20. The outer ring 18 is interference-fitted with the inner wall of the rotating tube 15, so that the outer ring 18 can drive the rotating tube 15 to rotate together. The inner ring 19 is coaxially connected to the output shaft of the micro motor 14 through a rotating shaft 21. The three negative pressure blades 20 are circumferentially distributed between the outer ring 18 and the inner ring 19.
[0059] Hose 22 is connected to the center of the end of the rotating tube 15.
[0060] In this embodiment, a threaded hole is provided at the bottom right side of the sleeve 1, and a collection bottle 23 is threadedly connected to the threaded hole. An exhaust pipe 24 is also inserted into the upper side of the collection bottle 23. A support net and activated carbon 25 are provided on one side of the exhaust pipe 24. A guide ring 26 is also installed on the right side inside the sleeve 1. The inner side of the guide ring 26 is a conical surface. One end of the guide ring 26 is located on one side of the collection pipe 16, and the other end is close to the connection between the collection bottle 23 and the sleeve 1. The lowest point of the conical surface is located on one side of the collection bottle 23.
[0061] The specific working process of this embodiment:
[0062] Before providing emergency care to an epileptic patient, the rescuer holds the sleeve 1, using its anti-slip texture for a more secure grip, and uses one finger to pull upwards on the limiting pin 10, separating the limiting pin 10 from the limiting hole 2, allowing the positioning block 9 to slide freely on the sleeve 1. At this point, the fixed slider is moved, using the push rod 12 to push the two flexible pads 4 to the left, so that most of the left side of the two flexible pads 4 is outside the sleeve 1. The rescuer then presses the left sides of the two flexible pads 4 together, forming a triangular structure.
[0063] During the rescue, the rescuer holds the triangular structure and gently and quickly inserts it a certain distance into the patient's mouth. Because the left ends of the two flexible pads 4 are abutting each other, and with the help of the two tilted flexible pads 4, it is easier to enter the patient's mouth. Then, the positioning block 9 is pulled to the right, and the push rod 12 moves the flexible pads 4 to the right. Since the patient will involuntarily bite down, the right ends of the two flexible pads 4 gradually move closer to the side wall of the sleeve 1, and the protrusions 6 on the surface of the flexible pads 4 provide stable occlusal limiting points for the teeth, which helps improve the stability of the occlusal points. When the two flexible pads 4 are close to the sleeve 1, their left ends move away from each other. This separation of the left sides of the two flexible pads 4 opens the patient's mouth, effectively preventing the patient's tongue from being bitten and creating a clear airway in the center of the mouth.
[0064] During the continuous movement of the flexible pad 4, the left ends of the two flexible rods 7 gradually separate from each other to a parallel state. After reaching the parallel state, due to the clenching action of the epilepsy patient, the flexible rods 7 cannot rotate as a whole. Simultaneously, as the flexible pad 4 moves, the left ends of the two flexible rods 7 deform and deflect, thereby causing the corresponding ends of the flexible pad 4 to flip. This ensures that the distance between the two flexible pads 4 in the oral cavity is greater than the opening gap of the epilepsy patient's mouth, preventing the flexible pads 4 from accidentally slipping out of the patient's mouth and ensuring the stability of the patient's mouth opening. Furthermore, after the two flexible pads 4 are lifted, the rounded corner design on the left side of the flexible pad 4 prevents secondary damage to the oral cavity wall. After the position of the flexible pad 4 is adjusted, the limiting pin 10 can be lowered. At this time, the limiting pin 10 engages with the limiting hole 2, fixing the position of the flexible pad 4.
[0065] After the patient's mouth is opened, the rescuer activates the micro motor 14. Once powered on, the micro motor 14 begins to rotate. Its output shaft drives the inner ring 19 of the negative pressure fan via the rotating shaft 21, causing the three negative pressure blades 20 and the outer ring 18 to rotate synchronously. Because the outer ring 18 of the negative pressure fan is press-fitted to the inner wall of the rotating tube 15, the rotating tube 15 rotates along with it, causing the flexible tube 22 connected to its end to change the suction direction within the mouth. The continuous negative pressure suction generated by the rotating fan is transmitted through the rotating tube 15 to the end of the flexible tube 22, actively drawing the accumulated sputum and secretions from the patient's mouth into the flexible tube 22. The secretions pass sequentially through the flexible tube 22 and the rotating tube 15 before reaching the collection tube 16. Under centrifugal force, they smoothly pass through the one-way valve 17 and enter the sleeve 1. At this point, guided by the conical surface of the guide ring 26, the secretions flow along the inclined plane to the lowest point and finally enter the threaded collection bottle 23 for temporary storage. The continuously rotating hose 22 can clean secretions from different parts of the mouth from multiple angles. At the same time, the gas discharged by the negative pressure fan is discharged through the exhaust pipe 24 on the upper side of the collection bottle 23. The activated carbon 25 inside the exhaust pipe 24 can absorb odors and improve the air quality at the scene.
[0066] Once the seizure stops and the patient calms down, the rescuer first shuts off the micro motor 14, then pulls up the limiting pin 10 to disengage it from the limiting hole 2, releasing the locking state of the positioning block 9. Next, the positioning block 9 is moved to the left, causing the push rod 12 to pull the two flexible pads 4 back towards the center. The deformed part of the flexible rod 7 begins to recover, restoring the device to its initial triangular contracted state, facilitating its removal from the patient's mouth without damage. Finally, the collection bottle 23 is unscrewed to collect the secretions, and the sleeve 1, flexible pads 4, and hose 22 of the device are cleaned and disinfected for future use. Throughout the entire operation, the rescuer's hands never need to directly contact the inside of the patient's mouth, effectively avoiding the risk of being bitten. Simultaneously, the supporting role of the flexible pads 4 and the synergistic effect of the negative pressure cleaning function solve the key problems of obstructed ventilation and secretion blockage in traditional methods.
