Abstract
Description
Technical Field
[0001] This invention specifically relates to a portable device for preventing epileptic seizures. Background Technology
[0002] Epilepsy is a chronic, non-communicable brain disorder affecting approximately 50 million people worldwide. It is characterized by recurrent seizures. During a seizure, a brief, involuntary convulsion occurs in a part of the body or the entire body, sometimes accompanied by loss of consciousness and urinary or fecal incontinence. Seizures are caused by abnormal electrical activity in a group of brain cells. Different parts of the brain can become sites of this abnormal discharge. Seizures range from very brief loss of consciousness or muscle reflexes to severe and continuous convulsions. The frequency of seizures also varies, from fewer than once a year to several times a day.
[0003] During an epileptic seizure, patients may bite their tongue or mouth, causing serious injury. Therefore, special designs are needed to protect the oral cavity. Current protective measures mostly rely on manual intervention, such as forcibly inserting gauze or a tongue depressor to support the patient's mouth.
[0004] However, currently, when patients have epileptic seizures, most of them rely on manually opening their mouths and inserting a bite stick to support their teeth. However, manually opening the mouth can easily cause injury to both the patient and the operator. Moreover, opening the mouth and inserting the bite stick requires multiple people to operate, which cannot quickly protect the patient. As a result, the probability of injury to the mouth and tongue remains high. In view of this, a portable epileptic seizure protection device is proposed to solve the above problems. Summary of the Invention
[0005] To address the shortcomings of existing technologies, this invention proposes a portable epileptic seizure protection device to solve the technical problems mentioned in the background art, where currently, when patients have epileptic seizures, they mostly rely on manually opening their mouths and inserting a bite stick to support their teeth. However, manually opening the mouth can easily cause injury to both the patient and the operator, and multiple people are required to operate the opening of the mouth and insert the bite stick, making it impossible to quickly protect the patient.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a portable epileptic seizure prevention device, comprising:
[0007] The mounting bracket has a mounting groove, in which a biting rod is slidably disposed. The mounting bracket is also provided with a handle for fixed installation and a hinged operating handle.
[0008] Two sets of support frames are arranged opposite each other and are slidably disposed on both sides of the mounting slot at the end of the mounting frame;
[0009] A drive mechanism, mounted on the mounting bracket and connected to the two sets of support brackets, converts the rotation of the operating handle into driving the two sets of support brackets to slide relative to each other; and
[0010] A propulsion mechanism is mounted on the mounting bracket and connected to the bite stick to convert the rotation of the operating handle into driving the bite stick to slide out of the mounting slot.
[0011] In a preferred embodiment, the mounting bracket is provided with a mounting plate at one end, and the support bracket is provided with a snap-fit bracket at one end. The snap-fit bracket is slidably snapped onto the mounting plate. The mounting plate is also provided with a locking component connected to the snap-fit bracket. The locking component can selectively lock or unlock the sliding of the support bracket in one direction.
[0012] In a preferred embodiment, the locking component includes:
[0013] A mounting frame is provided on the mounting plate;
[0014] A ratchet rack is laterally slidable within the mounting frame and extends beyond the mounting frame. A first elastic element is provided between the ratchet rack and the inner wall of the mounting frame. A pull ring extending beyond the mounting frame is also provided on the ratchet rack.
[0015] A ratchet groove is provided on the mounting frame and can engage with the ratchet rack.
[0016] In a preferred embodiment, the ends of the two sets of support frames are provided with arc-shaped opening seats, the two sets of opening seats cooperate to form a conical protrusion, and the opposing sides of the two sets of support frames are provided with limit grooves.
[0017] In a preferred embodiment, both sets of support frames are provided with a lip plate on their opposite sides.
[0018] In a preferred embodiment, the drive mechanism includes:
[0019] A drive frame is slidably disposed within the mounting frame. A connecting column is provided at the end of the drive frame. A sliding groove is provided on the mounting frame, and the connecting column is slidably engaged within the sliding groove.
[0020] The drive arm, having multiple sets, has one end hinged to the connecting column and the other end hinged to the support frame; and
[0021] A transmission assembly is disposed on the operating handle and connected to the drive frame to convert the rotation of the operating handle into driving the sliding of the drive frame.
[0022] In a preferred embodiment, the transmission assembly includes:
[0023] A sliding frame is mounted on the operating handle;
[0024] A drive column is mounted on the drive frame and slidably engaged within the slide frame; and
[0025] A second elastic element is disposed between the drive frame and the handle.
[0026] In a preferred embodiment, a C-shaped fixing seat is slidably disposed in the mounting groove, a flexible material stop is disposed in the opening of the fixing seat, the biting rod is engaged in the fixing seat and abuts against the stop, and the pushing mechanism is disposed on the operating handle and connected to the fixing seat.
[0027] In a preferred embodiment, the propulsion mechanism includes:
[0028] A drive gear is disposed on the operating handle at the hinge point with the mounting bracket;
[0029] A driven gear, rotatably mounted on the mounting bracket along its axis, meshes with the driving gear; the driven gear is provided with a drive rod; and
[0030] The push rod is hinged at one end to the fixed base and at the other end to the end of the drive rod away from the driven gear.
[0031] In a preferred embodiment, one side of one set of the support frame is hinged with an L-shaped frame, and one side of the support frame is provided with a protrusion and a slidably mounted wedge block. One end of the L-shaped frame abuts against the protrusion, and the end of the wedge block is provided with a third elastic member that abuts against the inner side of the support frame.
[0032] Compared with the prior art, the present invention has the following beneficial effects:
[0033] When using this device, the ends of the two support frames are inserted into the patient's mouth to support the teeth. Then, by gripping the handle and operating lever, the operating lever rotates along its hinge point with the mounting frame. During the rotation of the operating lever, the drive mechanism converts the rotation into driving the two support frames to slide relative to each other, thus opening the patient's teeth. This is more convenient and faster than manually opening the teeth. At the same time, the pushing mechanism converts the rotation of the operating lever into driving the biting stick to slide out of the mounting slot. The device can then be removed, and the biting stick can be quickly placed into the patient's mouth, preventing the patient from biting their tongue or mouth due to uncontrolled teething during an epileptic seizure. The entire operation can be completed by a single person, making it more convenient and timely to open the patient's mouth. This avoids situations where there is insufficient personnel to protect epileptic patients. Furthermore, the device has a compact structure, making it easy to carry and convenient for timely protection during epileptic seizures. Attached Figure Description

[0044] The present invention will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present invention and should not be construed as limiting the scope of protection of the present invention. Those skilled in the art can make some non-essential improvements and adjustments to the present invention based on the above application content.
[0045] Example:
[0046] like Figure 1 , 2 As shown in Figure 7, the present invention provides a portable epileptic seizure prevention device, including a mounting frame 1 with a mounting groove 7. Support frames 19 are slidably mounted on both sides of the mounting frame 1 located at the ends of the mounting frame 1 within the mounting groove 7. The ends of the two sets of support frames 19 are provided with arc-shaped opening seats 22, which cooperate to form a conical protrusion. Limiting grooves 23 are provided on the opposite sides of the two sets of support frames 19. A baffle plate 24 is provided on the opposite sides of both sets of support frames 19.
[0047] In use, the device involves inserting two sets of support brackets 19 between the upper and lower teeth of a patient experiencing an epileptic seizure. The opening mechanism 22 facilitates insertion, allowing the two sets of support brackets 19 to be pushed into the patient's interdental space with only a small gap, until the patient's upper and lower teeth are respectively engaged in the two limiting slots 23. This prevents the patient's teeth from dislodging from the support brackets 19 when they are subsequently opened. The lip guard 24 prevents excessive force during insertion, which could cause the support brackets 19 to extend too far and injure the patient's oral cavity. Therefore, the device provides safe oral protection for the patient.
[0048] like Figure 1 , 2 As shown in Figure 5, in this embodiment, the mounting frame 1 is also provided with a fixedly mounted handle 2 and a hinged operating handle 3. The mounting frame 1 is provided with a drive mechanism connected to two sets of support frames 19. The drive mechanism converts the rotation of the operating handle 3 into driving the two sets of support frames 19 to slide relative to each other. The drive mechanism includes a drive frame 29 slidably disposed in the mounting frame 1. A connecting post 30 is provided at the end of the drive frame 29. A sliding groove 31 is provided on the mounting frame 1. The connecting post 30 is slidably locked in the sliding groove 31. It also includes multiple sets of drive arms 32. One end of the drive arm 32 is hinged to the connecting post 30, and the other end is hinged to the support frame 19. The operating handle 3 is provided with a transmission assembly connected to the drive frame 29. The transmission assembly converts the rotation of the operating handle 3 into controlling the sliding of the drive frame 29. The transmission assembly includes a sliding frame 4 disposed on the operating handle 3. A drive post 33 is disposed on the drive frame 29. The drive post 33 is slidably locked in the sliding frame 4. A second elastic member 5 is provided between the drive frame 29 and the handle 2.
[0049] After the two sets of support frames 19 are placed between the patient's upper and lower teeth, the operating handle 3 can be squeezed to close with the handle 2. During the movement, the operating handle 3 squeezes the second elastic element 5. At the same time, the drive frame 29 is driven to slide on the mounting frame 1 through the cooperation of the drive column 33 and the slide frame 4. During the sliding process, the drive frame 29 drives the connecting column 30 to slide in the slide groove 31. The connecting column 30 drives the support frame 19 to slide through the drive arm 32. The two sets of support frames 19 slide in opposite directions, which can quickly control the opening of the patient's mouth.
[0050] like Figure 5 , 6 As shown in Figures 7 and 8, in this embodiment, a mounting plate 14 is provided at the end of the mounting bracket 1, and a snap-fit bracket 20 is provided at the end of the support bracket 19. The snap-fit bracket 20 is slidably snapped onto the mounting plate 14. A locking assembly connected to the snap-fit bracket 20 is also provided on the mounting plate 14. The locking assembly can selectively lock or unlock the sliding of the support bracket 19 in one direction. The locking assembly includes a mounting frame 15 provided on the mounting plate 14. A ratchet rack 16 is slidably installed in the mounting frame 15. The teeth of the ratchet rack 16 extend out of the mounting frame 15. A first elastic element 18 is provided between the ratchet rack 16 and the inner wall of the mounting frame 15. A pull ring 17 extending out of the mounting frame 15 is also provided on the ratchet rack 16. A ratchet groove 21 is provided on the mounting frame 15, which can engage with the ratchet rack 16.
[0051] During movement, the support frame 19 is positioned by the engagement of the locking bracket 20 and the mounting plate 14. As the two sets of support frames 19 are moved by gripping the operating handle 3, the locking bracket 20 slides on the mounting plate 14. Under the action of the first elastic element 18, the ratchet rack 16 engages within the ratchet groove 21, thus unidirectionally locking the position of the support frame 19. This prevents the support frame 19 from closing in the opposite direction due to the patient's teeth biting when the operator's hand strength is insufficient. Furthermore, it eliminates the need for the operator to continuously grip the operating handle 3, improving the reliability of the device. Pulling the pull ring 17 disengages the ratchet rack 16 from the ratchet groove 21, releasing the lock on the support frame 19 and allowing for quick and easy removal of the device.
[0052] like Figure 2 , 4As shown, in this embodiment, a biting rod 10 is slidably disposed in the mounting groove 7, and a pushing mechanism connected to the biting rod 10 is disposed on the mounting frame 1. The pushing mechanism converts the rotation of the operating handle 3 into driving the biting rod 10 to slide out of the mounting groove 7. A C-shaped fixing seat 8 is slidably disposed in the mounting groove 7. A flexible material stop block 9 is disposed in the opening of the fixing seat 8. The biting rod 10 is locked in the fixing seat 8 and abuts against the stop block 9. The pushing mechanism delivers the biting rod 10 to the operating handle 3 and connects it to the fixing seat 8. The pushing mechanism includes a driving gear 6 disposed on the operating handle 3 at the hinge point with the mounting frame 1. A driven gear 13 is disposed on the mounting frame 1. The driven gear 13 meshes with the driving gear 6. A drive rod 11 is disposed on the driven gear 13. One end of the pushing rod 12 is hinged to the fixing seat 8, and the other end is hinged to the end of the drive rod 11 away from the driven gear 13.
[0053] During the rotation of the control handle 3, the drive gear 6 is driven to rotate. The drive gear 6, in turn, drives the driven gear 13 to rotate, which in turn drives the drive rod 11 to swing. During the swing, the drive rod 11 controls the fixed seat 8 to slide in the mounting groove 7 via the push rod 12. The mounting groove 7 positions the sliding of the fixed seat 8. When the two sets of support frames 19 are opened, they can also position the sliding of the fixed seat 8, providing a large space for the sliding of the fixed seat 8 until the biting stick 10 moves into the patient's mouth. Then the device is disassembled so that the biting stick 10 remains in the mouth. The biting stick 10 supports the patient's teeth, freeing the operator's hands to perform other first aid measures on the patient. This avoids prolonged use of the device and prevents damage to the patient's incisors.
[0054] like Figure 2 , 3 As shown in Figures 4 and 7, in this embodiment, one of the support frames 19 is hinged to an L-shaped frame 25 on one side. A protrusion 26 and a slidably mounted wedge block 27 are provided on one side of the support frame 19. One end of the L-shaped frame 25 abuts against the protrusion 26, and the end of the wedge block 27 is provided with a third elastic member 28 that abuts against the inner side of the support frame 19. The L-shaped frame 25 is simply limited by the protrusion 26 to prevent it from rotating. During the sliding process, the bite stick 10 pushes the L-shaped frame 25 to rotate through one end until one end pushes the wedge block 27 to slide and retract through the inclined surface of the wedge block 27 until the L-shaped frame 25 is inserted into the inside of the wedge block 27. Under the action of the third elastic element 28, the wedge block 27 is extended to lock the L-shaped frame 25 in one direction. This allows the bite stick 10 to be limited when the pull ring 17 is pulled to release the fixation of the support frame 19 and the second elastic element 5 is reset to retract the fixing seat 8. This allows the bite stick 10 to detach from the fixing seat 8 and remain in the patient's mouth, improving the convenience of the device during use.
[0055] Specific usage and beneficial effects of the present invention:
[0056] When using this device, the ends of the two sets of support frames 19 are inserted into the patient's mouth to support the teeth. Then, by gripping the handle 2 and the operating handle 3, the operating handle 3 is rotated along its hinge point with the mounting frame 1. During the rotation of the operating handle 3, the drive mechanism converts the rotation into driving the two sets of support frames 19 to slide relative to each other, thereby opening the patient's teeth. This is more convenient and faster than manually opening the teeth. At the same time, the push mechanism converts the rotation of the operating handle 3 into driving the biting stick 10 to slide out of the mounting slot 7. The device can then be removed, and the biting stick 10 can be quickly placed into the patient's mouth, preventing the patient from biting their tongue or mouth due to uncontrolled teeth during an epileptic seizure. The entire operation can be completed by a single person, making it more convenient and timely to open the patient's mouth. This avoids the inability to protect epileptic patients when there are insufficient personnel. In addition, the entire device has a compact structure, making it easy to carry and convenient for timely protection of epileptic patients during a seizure.
[0057] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above. Modifications or improvements can be made to the present invention, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
