Technical Field
[0001] This utility model relates to the field of auxiliary device technology, and in particular to an auxiliary device for the treatment of benign paroxysmal positional vertigo (BPPV). Background Technology
[0002] Benign paroxysmal positional vertigo (BPPV), commonly known as "ear stone disease," is the most common peripheral vestibular disorder. The pathogenesis of BPPV is as follows: otolith particles on the macula of the utricle fall off and enter the lumen of the semicircular canals. When the head position changes relative to the direction of gravity, the otolith particles are displaced relative to the wall of the semicircular canals due to gravity, causing endolymphatic flow and resulting in the displacement of the ampulla crest cap, thus producing corresponding signs and symptoms.
[0003] The direction, duration, and movement characteristics of nystagmus are important indicators for determining the possible location of otoliths in the semicircular canals. However, postural tests and repositioning techniques often require the patient to rotate their head to a fixed angle to ensure the semicircular canal containing the otoliths is in a vertical position, with each position held for about half a minute. In clinical practice, it is difficult to accurately determine the angle of head rotation, and if the patient's nystagmus is weak during positional tests, it is difficult for the examiner to observe. Furthermore, the treatment effect is easily affected by individual techniques and methods.
[0004] Currently, patients with weak nystagmus need to wear a gyroscope. The gyroscope is usually fixed to the patient's head with a rope or strap, which makes operation inconvenient. If it is fixed too tightly, it can cause pressure on the patient. If it is fixed too loosely, the gyroscope may not rotate in sync with the patient's head when the patient's head is turned, resulting in deviation.
[0005] Therefore, there is an urgent need to provide an auxiliary device for the treatment of benign paroxysmal positional vertigo (BPPV) to solve the above problems. Utility Model Content
[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology, which requires patients with weak nystagmus to wear a gyroscope. The gyroscope is usually fixed to the patient's head with a rope or strap, which makes operation inconvenient. If the fixation is too tight, it will cause pressure on the patient. If the fixation is too loose, the rotation of the gyroscope will not follow the rotation of the patient's head when the patient's head is turned, causing deviation. This utility model provides an auxiliary device for the treatment of benign paroxysmal positional vertigo (BPPV).
[0007] To solve the above-mentioned technical problems, the present invention provides a technical solution: an auxiliary device for treating benign paroxysmal positional vertigo (BPPV), including a headband, a display screen disposed on the top of the headband, and a gyroscope disposed on the bottom of the display screen, wherein adjustment components are disposed on both sides of the headband;
[0008] Both ends of the headband are provided with connecting straps, and the adjustment component is disposed between the headband and the connecting straps;
[0009] The adjustment assembly includes a storage slot at the end of the headband, an extension strap inside the storage slot, and a locking unit on the side of the extension strap.
[0010] A connecting unit is provided between the connecting strip and the extension strip.
[0011] The present invention is further configured such that a voice broadcaster and a control component are respectively installed on the outer sides of the two connecting strips.
[0012] The present invention is further configured such that: the extension strip has an internal hollow structure, and arc-shaped grooves are provided on the opposite sides of the extension strip.
[0013] The present invention is further configured such that: each adjusting component has two sets of locking units, and the two sets of locking units are arranged opposite to each other on the outer side of the extension belt;
[0014] The locking unit includes a mounting groove disposed inside the side wall of the headband, a movable rod movably disposed inside the mounting groove, a limiting ring mounted on the outside of the movable rod, and a pressing member disposed on the side of the limiting ring. One end of the movable rod extends into the extension belt through the arc-shaped groove, and a locking block is installed on one end of the movable rod. An arc-shaped toothed ring is installed on the inner side wall of the extension belt, and a groove that matches the toothed pattern in the arc-shaped toothed ring is opened on the side of the locking block.
[0015] The present invention is further configured such that: one end of the movable rod extends through to the outside of the headband, and a pressing block is installed at one end of the movable rod.
[0016] The present invention is further configured such that: the connecting unit includes a slot disposed at the end of the connecting strip, an insert block disposed inside the slot, a positioning hole disposed on the side of the insert block, and a positioning portion disposed on the side of the positioning hole.
[0017] The present invention is further configured such that: the positioning part includes a movable groove disposed on the side wall of the connecting belt, a positioning rod movably disposed inside the movable groove, a limiting plate installed on the outside of the positioning rod, and a reset member disposed on the side of the limiting plate, wherein one end of the positioning rod is adapted to the size of the positioning hole.
[0018] The beneficial effects of this utility model are as follows:
[0019] 1. This utility model, through the setting of the adjustment component, in conjunction with pressing the pressing block, causes the movable rod to move into the mounting groove, thereby causing the locking block to move into the extension band. This causes the groove on the side of the locking block to separate from the arc-shaped toothed ring, thereby releasing the limitation on the extension band. In conjunction with the sliding connecting band, the extension band slides along the inside of the storage groove, thereby adjusting the overall length of the headband to adapt to the head of different patients. After adjustment, the pressing block is released. Under the elastic recovery of the squeezing component and the action of the limiting ring, the groove on the side of the locking block engages with a tooth in the arc-shaped toothed ring, thereby limiting the position of the extension band and effectively fixing the gyroscope to the patient's head, thus avoiding excessive pressure that could cause the gyroscope to malfunction.
[0020] 2. With the connection unit provided in this utility model, when it is necessary to repair the entire device or replace parts, the positioning rod is pulled outward to separate one end of the positioning rod from the positioning hole, thereby releasing the restriction on the insertion block. Pulling the extension belt outward can separate it from the connecting belt, thus facilitating the replacement of the connecting belt or the repair of the voice broadcaster and control components.

[0027] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.
[0028] Please see Figure 1 - Figure 5 An auxiliary device for treating benign paroxysmal positional vertigo (BPPV) includes a headband 1, a display screen 2 located at the top of the headband 1, and a gyroscope 3 located at the bottom of the display screen 2. Adjustment components 4 are provided on both sides of the headband 1. The adjustment components 4 are used to adjust the overall length of the headband 1 to adapt to the size of the patient's head and avoid the headband 1 being too tight on the patient's head, which would cause the gyroscope 3 to malfunction.
[0029] Both ends of the headband 1 are provided with connecting straps 5, and the adjustment component 4 is located between the headband 1 and the connecting straps 5;
[0030] The adjustment component 4 includes a storage groove 41 disposed at the end of the headband 1, an extension band 42 disposed inside the storage groove 41, and a locking unit 43 disposed on the side of the extension band 42.
[0031] A connecting unit 44 is provided between the connecting strip 5 and the extension strip 42.
[0032] Among them, a voice broadcaster 6 and a control component 7 are respectively installed on the outer side of the two connecting strips 5. Preferably, the control component 7 is the power switch and volume control button of the whole device.
[0033] By activating the control component 7, the display screen 2 simulates the dynamic movement of otoliths. The built-in gyroscope 3 determines whether the angle of head movement is correct and issues a voice instruction. Then, the voice broadcaster 6 guides the patient to adjust the angle, position, and time of head movement to meet the requirements of the treatment tutorial.
[0034] The extension strip 42 has an internal hollow structure, and arc-shaped grooves 421 are provided on the opposite sides of the extension strip 42.
[0035] Each adjustment component 4 has two sets of locking units 43, which are arranged opposite to each other on the outside of the extension belt 42.
[0036] The locking unit 43 includes a mounting groove 431 disposed inside the side wall of the headband 1, a movable rod 432 movably disposed inside the mounting groove 431, a limiting ring 433 mounted on the outside of the movable rod 432, and a pressing member 434 disposed on the side of the limiting ring 433. One end of the movable rod 432 extends into the extension belt 42 through the arc-shaped groove 421, and a locking block 435 is installed on one end of the movable rod 432. An arc-shaped toothed ring 436 is installed on the inner side wall of the extension belt 42. A groove is opened on the side of the locking block 435 to match the toothed pattern in the arc-shaped toothed ring 436. Preferably, the pressing member 434 is a compression spring.
[0037] One end of the movable rod 432 extends through to the outside of the headband 1, and a pressing block 4321 is installed on one end of the movable rod 432.
[0038] The connecting unit 44 includes a slot 441 disposed at the end of the connecting strip 5, a plug 442 disposed inside the slot 441, a positioning hole 443 disposed on the side of the plug 442, and a positioning part 444 disposed on the side of the positioning hole 443. Preferably, the cross-sections of the plug 442 and the slot 441 are both T-shaped structures.
[0039] The positioning part 444 includes a movable groove disposed on the side wall of the connecting belt 5, a positioning rod 4441 movably disposed inside the movable groove, a limiting plate 4442 installed on the outside of the positioning rod 4441, and a reset member 4443 disposed on the side of the limiting plate 4442. One end of the positioning rod 4441 is adapted to the size of the positioning hole 443. Preferably, the reset member 4443 is a reset spring.
[0040] In use, the overall length of the headband 1 needs to be adjusted for different patients. The patient presses the pressing block 4321 to move the movable rod 432 into the mounting groove 431, thereby moving the locking block 435 into the extension band 42. This causes the groove on the side of the locking block 435 to separate from the arc-shaped toothed ring 436, thus releasing the restriction on the extension band 42. The extension band 42 slides along the storage groove 41 by sliding the connecting band 5, thereby adjusting the overall length of the headband 1 to suit the head of different patients. After adjustment, the pressing block 4321 is released. Under the elastic recovery of the squeezing member 434 and the action of the limiting ring 433, the groove on the side of the locking block 435 engages with a tooth in the arc-shaped toothed ring 436, thereby limiting the position of the extension band 42 and preventing excessive pressure from causing the gyroscope 3 to malfunction.
[0041] When the device needs to be repaired or parts replaced, the positioning rod 4441 is pulled outward to separate one end of the positioning rod 4441 from the positioning hole 443, thereby releasing the restriction on the insertion block 442. The extension belt 42 is then pulled outward to separate it from the connecting belt 5, making it easier to replace the connecting belt 5 or repair the voice broadcaster 6 and control components 7.
[0042] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
