Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to an auxiliary device for repositioning and positioning in patients with benign paroxysmal positional vertigo (BPPV). Background Technology

[0002] Benign paroxysmal positional vertigo (BPPV) is a common inner ear disease caused by the detachment of calcium carbonate crystals (otoliths) from the inner ear and their entry into the semicircular canals, resulting in temporary vertigo and severely impacting quality of life. The core treatment method involves using specific techniques to help the detached otoliths return to their original position.

[0003] For example, Chinese patent CN223232897U discloses a repositioning device for benign paroxysmal positional vertigo (BPPV). This device rotates inside a steering ring via a control lever, causing the steering ring to rise and fall. The rotation of the fixed plate drives the device and the patient to rotate 360 ​​degrees. The device rotates 360 degrees between the fixed plates, thereby achieving precise positioning, quantitative and speed-controlled diagnosis and repositioning, and improving the treatment effectiveness of BPPV.

[0004] In existing technologies, otolithic repositioning devices are often used to assist in improving the repositioning accuracy in otolithiasis. However, due to the high cost of high-precision repositioning devices, they are not widely used in most rural hospitals. In actual repositioning operations, manual repositioning still relies on the doctor's experience. During clinical treatment, the repositioning success rate varies greatly among different doctors, especially for some novice doctors, who find it difficult to accurately control the repositioning angle, which can adversely affect the repositioning success rate during clinical treatment.

This can reduce the discomfort during the repositioning treatment of benign paroxysmal positional vertigo to a certain extent. By changing the position of the indicator plate and using the scale lines on the ruler surface, the rotation angle of the swing rod can be directly monitored, so that the bending degree of the liner can be adjusted more accurately, which helps to further improve the accuracy of the repositioning operation.

[0019] This solution, by setting up a rotating component, allows observation of the rotation angle of the shield by observing the position of the scale corresponding to the indicator plate. This not only enables accurate control of the rotation angle of the patient's head, helping to improve the repositioning treatment accuracy for patients with benign paroxysmal positional vertigo (BPPV), but also facilitates novice doctors' internship operations, helping to improve the repositioning success rate in primary hospitals. Furthermore, the device has a simple structure and low manufacturing cost, making it easy to popularize and use in rural primary hospitals.

[0020] This solution incorporates a breathable component; the ventilation holes on the surface of the protective shield effectively improve its breathability. The deformation of the bladder promotes airflow within the shield, further enhancing ventilation and reducing discomfort during wear. The connecting plate gradually pushes the clamping plate through the bladder, increasing the pressure between the clamp and the patient's head, thus maintaining stability between the shield and the patient's head. This effectively reduces the risk of relative movement between the shield and the patient's head during treatment and repositioning, ensuring operational precision. Attached Figure Description

[0031] To make the technical problems, technical solutions and advantages of the present invention clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0032] like Figures 1 to 8As shown, embodiments of the present invention provide a repositioning and positioning aid for benign paroxysmal positional vertigo (BPPV). The following describes... Figure 1 The device is described with reference to its arrangement, including a protective cover 11 and a bracket 12. A rotating plate 41 is rotatably connected to the right end of the protective cover 11. The right end of the rotating plate 41 is fixedly connected to the bracket 12. A lifting assembly is provided on the right side of the rotating plate 41. The lifting assembly includes a liner 14 fixedly connected to the right end face of the rotating plate 41. Folding grooves 19 are alternately opened on the inner and outer walls of the liner 14. A mounting bracket 26 is fixedly connected to the lower outer surface of the liner 14. A movable seat 47 is fixedly connected to the outer surface of the mounting bracket 26. A through hole 50 is opened through the outer surface of the movable seat 47. A spiral sleeve 21 is threadedly connected to the outer surface of the bracket 12. A drive rod 48 is rotatably connected to the inner side of the spiral sleeve 21. A cam 49 is fixedly connected to the outer surface of the drive rod 48. The cam 49 is in rotatable contact with the inner surface of the through hole 50.

[0033] In this device, the protective cover 11 and the bracket 12 are rotatably connected by a rotating plate 41, which can flexibly adjust the angle of the patient's head and provide basic support for the repositioning operation.

[0034] In the support assembly, the folding groove 19 allows the liner 14 to bend in both inward and outward directions, thereby reducing bending resistance and adapting to the physiological curves of different patients' necks. When the drive rod 48 is rotated, the cam 49 on its outer surface will rotate into contact with the through hole 50 of the movable seat 47. The protrusion of the cam 49 can lift the movable seat 47, thereby driving the liner 14 to bend as a whole through the mounting bracket 26, realizing flexible adjustment of the bending angle of the liner 14.

[0035] The aforementioned spiral sleeve 21 is threadedly connected to the bracket 12. After adjustment, tightening the spiral sleeve 21 can fix the position of the drive rod 48 by the friction with the baffles 16 at both ends of the drive rod 48, so that the liner 14 maintains the set bending angle.

[0036] The device provided by this invention allows for precise adjustment of the bending angle of the liner 14 via the cam 49, ensuring close conformity to the physiological curve of the patient's neck for stable support and reducing patient discomfort during repositioning. The mechanically driven angle adjustment method is precise and controllable, avoiding angle deviations during manual repositioning and improving the accuracy of the repositioning operation. The overall structure consists of basic mechanical components such as a protective cover, bracket, and lifting assembly, without complex electronic control components, resulting in a simple structure, low manufacturing cost, and ease of widespread use in primary hospitals. The rotation of the rotating plate 41, combined with the angle adjustment of the liner 14, can adapt to the positional requirements of different repositioning techniques, improving the device's versatility.

[0037] The number of folding grooves 19 is several and they are arranged in a parallel array. The liner 14 is made of elastic material. The through hole 50 has a circular structure. The front and rear ends of the drive rod 48 are fixedly connected to baffles 16. The number of spiral sleeves 21 is two and they are symmetrically distributed. The side of the liner 14 away from the rotating plate 41 is fixedly connected to a connecting strip 20. The connecting strip 20 is fixedly connected to the inner surface of the bracket 12. The bracket 12 is annular.

[0038] The outer surface of the upper end of the protective cover 11 is embedded with a buffer groove 40. A buffer pad 18 is fixedly connected to the inner surface of the buffer groove 40. The buffer pad 18 is made of elastic material. A traction belt 15 is fixedly connected to the inner surface of the bracket 12. The traction belt 15 is fixedly connected to the liner 14 on the side away from the bracket 12. There are two sets of traction belts 15, which are symmetrically distributed. The traction belts 15 are made of elastic material.

[0039] By adopting the above technical solution, when medical staff in primary hospitals use a simple repositioning device to perform repositioning operations on patients with benign paroxysmal positional vertigo (BPPV), the protective shield 11 is worn on the patient's head, and the liner 14 is fitted against the patient's neck. To improve the doctor's operational precision, a support component is set up. The support component includes the liner 14, which is fixedly connected to the right end face of the rotating plate 41. The protective shield 11 is rotatably connected to the bracket 12 through the rotating plate 41. The liner 14 is fixed to the inside of the bracket 12 by the connecting strap 20. The traction straps 15 on both sides of the liner 14 can further improve the structural strength of the liner 14, thereby enabling the liner 14 to support and lift the patient's neck. Since there are certain differences in the physiological curve of different patients' necks, in order to make the liner 14 fit better against the patient's neck, components such as the mounting bracket 26 are set up. It is necessary to increase the size of the liner. When bending plate 14, the operator first rotates the screw sleeve 21 clockwise to disengage the screw sleeve 21 from the outer surface of the baffle 16. Then, the operator rotates the baffle 16, which drives the drive rod 48 to rotate synchronously. During the rotation of the drive rod 48, the cam 49 will rotate. During the rotation, the cam 49 will continuously contact the through hole 50 inside the movable seat 47. When the protrusion of the cam 49 flips upward, the protrusion of the cam 49 will push the movable seat 47 upward. At this time, the movable seat 47 will drive the mounting bracket 26 to move synchronously. The mounting bracket 26 will push the middle part of the liner plate 14 upward, which can effectively increase the bending degree of the liner plate 14. The folding groove 19 on the inner wall of the liner plate 14 can effectively reduce the bending deformation resistance of the liner plate 14, so that the liner plate 14 can be flexibly bent into different curvatures.

[0040] After the liner 14 is adjusted to the appropriate angle, the operator rotates the spiral sleeve 21 counterclockwise, so that the spiral sleeve 21 contacts the outer surface of the baffle 16. The friction between the spiral sleeve 21 and the baffle 16 can limit the position of the baffle 16, thus keeping the position of the baffle 16 and the drive rod 48 stable. By rotating the cam 49 at different angles, the bending angle of the liner 14 can be flexibly adjusted, so that the liner 14 can better match the physiological curve of the patient's neck, so that it can better support the patient's neck during the repositioning treatment, thereby reducing the discomfort during the repositioning treatment of benign paroxysmal positional vertigo to a certain extent. The buffer groove 40 inside the shield 11 is used to fix the buffer pad 18. The buffer pad 18 protrudes outside the buffer groove 40 and can produce elastic deformation, so that it can better cover the patient's head and help to initially limit the position of the patient's head.

[0041] Specifically, such as Figure 2 , Figure 4 , Figure 5 and Figure 8 As shown, an indicator component is provided on the lower side of the mounting bracket 26. The indicator component includes a mounting groove 30 that extends through the outer surface of the mounting bracket 26. A guide rod 27 is fixedly connected to the inner side of the mounting groove 30. A slot 22 is extended through the lower outer surface of the bracket 12. A movable rod 23 is fixedly connected to the inner surface of the slot 22. A swing rod 24 is rotatably connected to the outer surface of the movable rod 23, and one end of the swing rod 24 engages with the guide rod 27 on the mounting bracket 26. When the mounting bracket 26 moves up and down as the liner 14 bends, the swing rod 24 will rotate around the movable rod 23 via the guide rod 27.

[0042] The outer surface of the swing rod 24 is provided with a movable groove 25. The guide rod 27 passes through the movable groove 25 and passes through both ends of the swing rod 24 and slides in contact with the movable groove 25. An indicator plate 29 is fixedly connected to the lower outer surface of the swing rod 24. A scale 28 is fixedly connected to the lower side of the outer surface of the bracket 12. The scale 28 is embedded with graduation lines 31 on its outer surface. The scale 28 is semi-circular. The indicator plate 29 is located inside the scale 28 and slides in contact with the inner surface of the scale 28.

[0043] By adopting the above technical solution, in order to detect the bending angle of the liner 14, an indicator component is set up. The slot 22 on the surface of the bracket 12 is used to fix the movable rod 23. The movable rod 23 provides rotational support for the swing rod 24, so that the swing rod 24 can rotate with the movable rod 23 as the fulcrum. The movable groove 25 on the surface of the swing rod 24 is used to slide the guide rod 27. The mounting bracket 26 provides fixed support for the guide rod 27 through the mounting groove 30. When the movable seat 47 drives the mounting bracket 26 to move, the mounting bracket 26 will drive the guide rod 27 to move synchronously. When the guide rod 27 slides in the guide groove, it will drive the swing rod 24 to flip. During the flipping process, the swing rod 24 will drive the indicator plate 29 to move synchronously. The indicator plate 29 rotates and contacts the inner surface of the scale 28. By changing the position of the indicator plate 29 in conjunction with the scale line 31 on the surface of the scale 28, the flipping angle of the swing rod 24 can be intuitively monitored, so as to more accurately adjust the bending degree of the liner 14 and help to further improve the accuracy of the reset operation.

[0044] Specifically, such as Figure 4 and Figure 7 As shown, a rotating assembly is provided between the bracket 12 and the protective cover 11. The rotating assembly includes a limiting groove 42 embedded in the inner side of the protective cover 11. The limiting groove 42 is arc-shaped. A guide wheel 43 is rotatably connected to the inner side of the limiting groove 42. A limiting rod 44 is rotatably connected to the inner surface of the guide wheel 43. The side of the limiting rod 44 away from the guide wheel 43 is fixedly connected to the outer surface of the rotating plate 41.

[0045] The outer surface of the protective cover 11 is fixedly connected to an indicator plate 46, and the outer surface of the left end of the bracket 12 is fixedly connected to a scale 45. The scale 45 is arc-shaped, and the indicator plate 46 slides in contact with the inner surface of the scale 45. The rotating plate 41 has an L-shaped cross-section.

[0046] By adopting the above technical solution, after the shield 11 is worn on the patient's head, a rotating component is set up to allow the shield 11 to rotate flexibly with the patient's head. The rotating plate 41 rotates and contacts the outer surface of the shield 11. The rotating plate 41 supports the guide wheel 43 through the limiting rod 44. When the shield 11 and the rotating plate 41 move relative to each other, the guide wheel 43 rotates inside the limiting groove 42. The limiting groove 42 and the guide wheel 43 make the shield 11 rotate more smoothly. During the movement of the shield 11, the indicator plate 46 moves synchronously. The indicator plate 46 slides inside the scale 45. By observing the position of the indicator plate 46 corresponding to the scale 28, the rotation angle of the shield 11 can be observed. This not only allows for accurate control of the rotation angle of the patient's head, which helps improve the repositioning treatment accuracy for patients with benign paroxysmal positional vertigo (BPPV), but also facilitates the practice of novice doctors and helps improve the repositioning success rate in primary hospitals.

[0047] Specifically, such as Figure 4 and Figure 6 As shown, a limiting component is provided on the inner side of the protective cover 11. The limiting component includes a top rod 32 that is threadedly connected to the protective cover 11. A knob 51 is fixedly connected to the outer surface of the right end of the top rod 32. A connecting plate 34 is fixedly connected to the side of the top rod 32 away from the knob 51. A second storage groove 39 is embedded in the outer surface of the connecting plate 34. A bladder 36 is fixedly connected to the inner surface of the second storage groove 39.

[0048] A clamping plate 17 is fixedly connected to the outer surface of the bladder 36. The outer surface of the clamping plate 17 is arc-shaped and made of lightweight material. A spring 37 is fixedly connected to the inner surface of the bladder 36. There are two sets of springs 37, which are symmetrically distributed. A storage groove 33 is embedded in the inner surface of the protective cover 11.

[0049] By adopting the above technical solution, after the protective shield 11 is worn on the patient's head, a limiting function is set to keep the patient's head stable between the protective shield 11 and the patient's head. The protective shield 11 uses the storage slot 33 to store and limit the connecting plate 34, and the top rod 32 is used to support the rotation of the connecting plate 34. After the protective shield 11 is worn, the operator turns the knob 51. During the rotation of the knob 51, the top rod 32 will rotate synchronously. The top rod 32 is threadedly connected to the protective shield 11. As the top rod 32 rotates, it will move into the protective shield 11. During the movement, the top rod 32 will... The connecting plate 34 moves synchronously, and the connecting plate 34 provides elastic support to the clamping plate 17 through the bladder 36. The clamping plate 17 fits against the patient's head. As the connecting plate 34 moves, it gradually pushes the clamping plate 17 through the bladder 36, thereby increasing the squeezing force between the clamping plate and the patient's head to a certain extent. This ensures that the shield 11 and the patient's head remain stable. When treating and repositioning the patient's head, this effectively reduces the risk of relative movement between the shield 11 and the patient's head, thus effectively ensuring the accuracy of the operation.

[0050] Specifically, such as Figure 6 As shown, a ventilating component is provided on the outer side of the clamping plate 17. The ventilating component includes an air outlet 38 embedded in the outer surface of the clamping plate 17. The air outlet 38 is connected to the inside of the bladder 36. The number of air outlets 38 is several groups and they are distributed in a parallel array. A one-way air inlet pipe 35 is fixedly connected to the outer surface of the bladder 36. The one-way air inlet pipe 35 is connected to the inside of the bladder 36. A ventilating hole 13 is provided through the outer surface of the protective cover 11. A one-way valve is provided inside the air outlet 38.

[0051] By adopting the above technical solution, the ventilation holes 13 on the surface of the protective cover 11 can effectively improve the ventilation effect of the protective cover 11, thereby reducing the stuffiness during the wearing of the protective cover 11 to a certain extent. The connecting plate 34 provides elastic support to the clamping plate 17 through the bladder 36. When the patient's head moves, the bladder 36 will undergo a certain degree of elastic deformation. When the bladder 36 is squeezed, the gas inside the bladder 36 will be discharged into the protective cover 11 through the vent 38. When the bladder 36 moves back to its original position under the elastic force of the spring 37, the gas inside the storage slot 33 will enter the bladder 36 through the one-way air inlet pipe 35, thereby causing the bladder 36 to re-inflate. The deformation of the bladder 36 can promote the flow of air inside the protective cover 11, thereby effectively improving the ventilation effect inside the protective cover 11 and helping to further reduce the discomfort during the wearing of the protective cover 11.

[0052] The working process of the repositioning and positioning auxiliary device for benign paroxysmal positional vertigo (BPPV) provided by this invention is as follows: When the repositioning auxiliary device is working, the shield 11 is first worn on the patient's head, and the liner 14 is fitted against the patient's neck. At this time, the clamping plate 17 will fit against the patient's head. The connecting plate 34 provides elastic support to the clamping plate 17 through the capsule 36, thereby ensuring stability between the shield 11 and the patient's head. When adjusting the bending angle of the liner 14, the drive rod 48 rotates, which drives the cam 49 to rotate. The protrusion of the cam 49 pushes the movable seat 47 upward, thereby effectively increasing the bending degree of the liner 14 and making the liner 14 better match the physiological curve of the patient's neck. When the guide rod 27 slides inside the guide groove, it drives the swing rod 24 to rotate. During the rotation of the swing rod 24, it drives the indicator... The synchronous movement of the indicator plate 29, combined with the positional changes of the indicator plate 29 and the scale lines 31 on the surface of the scale 28, allows for intuitive monitoring of the rotation angle of the swing rod 24. The limit groove 42, in conjunction with the guide wheel 43, enables the shield 11 to rotate more smoothly. During the movement of the shield 11, the indicator plate 46 moves synchronously. The indicator plate 46 slides inside the scale 45. By observing the position of the indicator plate 46 corresponding to the scale 28, the rotation angle of the shield 11 can be controlled. This not only allows for accurate control of the rotation angle of the patient's head, but also, when the bladder 36 is compressed, the gas inside the bladder 36 is discharged into the shield 11 through the vent 38. The deformation of the bladder 36 promotes airflow inside the shield 11, thereby effectively improving the ventilation effect inside the shield 11.

[0053] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
