Description

Technical Field

[0001] This utility model relates to the technical field of otolithiasis treatment devices, and in particular to an otolithiasis repositioning indicator. Background Technology

[0002] Benign paroxysmal positional vertigo (BPPV), also known as otolithiasis, is a condition characterized by a spinning sensation and dizziness when the patient attempts to change the direction of their head, such as up, down, left, or right. Normally, otoliths are attached to the otolithic membrane. When certain factors cause otoliths to detach, these detached otoliths float in the endolymph, a fluid within the inner ear. When the head changes position, these semicircular canals also change position, causing the deposited otoliths to move with the fluid flow. This stimulates the hair cells in the semicircular canals, leading to intense vertigo that typically lasts only a few seconds to a few minutes. BPPV commonly affects the posterior semicircular canals and is prone to recurrence.

[0003] A search revealed a patent application with application number 202320424269.7 that discloses a repositioning indicator for benign paroxysmal positional vertigo (BPPV). The indicator includes a cap support, a support rod with cap clips and a semicircular canal simulator at each end. The semicircular canal simulator comprises two transparent, semi-circular vacuum tubes connected and symmetrically arranged. A cross-shaped fixing bracket is positioned between the two tubes. The semi-circular vacuum tubes contain an oil and an indicator ball. This BPPV repositioning indicator, through the cap support, facilitates fixing the semicircular canal simulator in front of the patient's eyes. The transparent semi-circular vacuum tubes simulate the posterior semicircular canal, allowing the patient to track the movement of the red indicator ball. The upper arc-shaped fixing sleeves at both ends of the cross-shaped fixing bracket are made pink and transparent, indicating the position the indicator ball should reach in each body position, enabling the patient to accurately adjust their position and facilitating BPPV repositioning.

[0004] The aforementioned patent describes a semicircular canal simulator at the front end of the support device to simulate the structure of the human semicircular canals. However, different patients have different head shapes. The semicircular canal simulator in the aforementioned patent uses a fixed angle design, which cannot be personalized according to the shape and size of the patient's head. The fixed angle design may not perfectly fit the head of each patient, thus affecting the treatment effect. Therefore, this device designs an adjustable semicircular canal simulator angle repositioning indicator for benign paroxysmal positional vertigo (BPPV). Utility Model Content

[0023] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] Example 1

[0025] See attached document Figure 1-5 The present invention proposes a repositioning indicator for benign paroxysmal positional vertigo (BPPV), comprising a cap body 10 and a half-scale simulator 30; wherein, the half-scale simulator 30 is prior art, and its structure will not be described in detail here.

[0026] The cap body 10 is equipped with a connecting component, which includes a connecting rod; wherein the connecting rod is an adjustable telescopic rod 20, the length of which can be adjusted to suit different patients.

[0027] The semi-scale simulator 30 is detachably mounted on the connecting rod. The end of the connecting rod away from the semi-scale simulator 30 is mounted on the cap body 10 through an adjustment mechanism. The adjustment mechanism includes two positioning plates 51 fixedly mounted on the outer wall of the connecting plate 21. Through holes are provided on the end of the connecting rod and the outer wall of the positioning plate 51. An adjusting bolt 52 is movably mounted inside the through hole. A locking nut 53 is threaded onto the adjusting bolt 52. The locking nut 53 is used to lock and fix the connecting rod and the positioning plate 51. Here, the installation angle of the semi-scale simulator 30 can be adjusted. When adjusting, the locking nut 53 can be rotated counterclockwise to release the fixing of the adjusting bolt 52. Then, the adjusting telescopic rod 20 can be rotated to adjust the angle. After adjustment, the locking nut 53 is locked back onto the adjusting bolt 52 so that the adjusting telescopic rod 20 can be clamped and fixed by the two positioning plates 51.

[0028] A connecting plate 21 is fixedly connected to the end of the telescopic rod 20 away from the semi-scale simulator 30. A fixing block 11 is fixedly installed on the outer wall of the hat body 10. The connecting plate 21 is installed on the fixing block 11 by a screw.

[0029] A connection box 31 is fixedly installed on the outer wall of the half-scale simulator 30. The connection box 31 has a slot 42 inside. A plug 41 is fixedly installed on the end of the adjusting telescopic rod 20 away from the hat body 10. The plug 41 is inserted into the slot 42 and fixed by a locking component. Here, the half-scale simulator 30 can be removed from the adjusting telescopic rod 20, which is convenient for subsequent maintenance or replacement of the half-scale simulator 30.

[0030] The locking assembly includes two mounting chambers 46 located inside the insert block 41. A slider 44 is slidably connected to the inner wall of the mounting chamber 46. A limiting post 43 is fixedly installed on the end wall of the slider 44. Through holes are symmetrically provided on the outer walls of the insert block 41 and the connecting box 31. The limiting post 43 moves through the inside of the through hole. A spring 45 is fixedly connected to the end wall of the slider 44. The end of the spring 45 away from the slider 44 is fixedly connected to the inner wall of the mounting chamber 46. When disassembling the half-scale simulator 30, the two limiting posts 43 can be pressed so that the ends of the limiting posts 43 enter the through holes on the insert block 41. At this time, the limitation of the limiting posts 43 on the insert block 41 can be released. Then, the insert block 41 can be pulled out from the slot 42 to disassemble the half-scale simulator 30 from the adjusting telescopic rod 20.

[0031] In this embodiment, when different patients use this device, the installation angle of the half-scale simulator 30 can be adjusted to suit different patients, thereby improving the treatment effect and the practicality of the device.
