Wearable otolith returning device

Abstract

The invention provides a wearable eardust returning device. The wearable eardust returning device comprises a vestibule model and a fixing strap, wherein the vestibule model comprises a semicircular canal model and an accommodating bag; the semicircular canal model comprises a front semicircular canal, a rear semicircular canal and an external semicircular canal; the accommodating bag comprises acenter accommodating cavity and a sound penetrating cavity; transparent liquid is stored in the semicircular canal model and the center accommodating cavity; and two ends of the front semicircular canal, two ends of the rear semicircular canal and two ends of the external semicircular canal are all located in the center accommodating cavity. In the treatment process of the wearable eardust returning device disclosed by the invention, the situation that eardust cannot be seen in the ear is converted into the situation that the eardust can be seen from outside, the position of an eardust simulacrum in the semicircular canal when a patient is under different body positions can be seen, the kinematic trajectory of the eardust in the semicircular canal can be more intuitively observed by a doctor, so that the patient is told to alternate an appropriate body position, the fallen eardust is returned to the vestibule, the success rate of eardust returning can be effectively increased, and thepain of the patient is alleviated.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a wearable otolith reset device. Background technique [0002] Otolithiasis, also known as benign paroxysmal positional vertigo, ranks highest in the incidence of vertigo, and the common manifestation is transient vertigo attacks related to posture. Patients often experience dizziness when turning over or getting up or lying down, and the duration of vertigo is usually less than 1 minute. The otolith is an important organ that controls the balance of the human body. Under normal circumstances, the otolith is in the utricle of the vestibule. Due to head trauma or local structural degradation due to old age, the otolith will fall off from its original position and move into the semicircular canal. After the patient's body position changes, the otoliths flow in the semicircular canal with the action of gravity, stimulating the vestibular terminal to induce vertigo. Among them, the s...

AI Technical Summary

Problems solved by technology

At present, doctors can diagnose otolithiasis based on the typical clinical manifestations of patients. However, because the anatomical structure of the inner ear vestibule and semicircular canal is relatively abstract, it is difficult for non-professional doctors to accurately judge the location of semicircular canal and otolith in each body position during the actual reset process. The position of the otolith is not conducive to the rapid reset of the otolith, which is also the main reason for the failure of the otolith reset
