BPPV diagnosis and reset training teaching device

Abstract

The invention discloses a BPPV diagnosis and reset training teaching device. The device comprises a fixing cap worn on a head, a vestibular model and three pairs of semicircular canal models are detachably arranged on the two sides, corresponding to the ears, of the fixing cap. The three pairs of semi-regular pipe models are arc-shaped pipelines. A cavity is formed in the vestibular model; the cavity is communicated with the three pairs of semicircular canal models. Each of three pairs of semicircular canal models comprise an upper semicircular canal, a rear semicircular canal and a horizontalsemicircular canal; touch chips are arranged on the inner side walls of the upper semicircular canal, the rear semicircular canal and the horizontal semicircular canal and in the vestibular model, the touch chips are connected with one another and are connected with a computer terminal through transmission lines in the vestibular model, and otolith steel balls for simulating otolith are arrangedin the three pairs of semicircular canal models. According to the invention, otolith movement and reduction techniques are simulated in the semicircular canals, so that doctors in the ear-nose-throatdepartment and the neurology department can quickly understand and quickly and skillfully master the diagnosis and reduction methods to perform timely diagnosis and effective reduction on a patient; the disease course is shortened obviously and the pain of the patient is alleviated.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a teaching device for BPPV diagnosis and reset training. Background technique [0002] Benign paroxysmal positional vertigo (BPPV) is a kind of paroxysmal short-term paroxysmal vertigo caused by head position changes and accompanied by characteristic nystagmus, also known as otolithiasis. Misdiagnosed as other diseases and delayed treatment, all three pairs of semicircular canals can occur, and can be divided into posterior semicircular canal (PC-BPPV), horizontal semicircular canal (HC-BP-PV), superior semicircular canal BPPV (SC-BPPV), and two Or two or more semicircular canals suffering from the four clinical types of mixed BPPV at the same time, which can be unilateral or bilateral; BPPV is a common disease in outpatient clinics, and it is also the main cause of vertigo. Manipulative reduction is the first choice for the treatment of benign positional vertigo. Different res...

[0002] Benign paroxysmal positional vertigo (BPPV) is a kind of paroxysmal short-term paroxysmal vertigo caused by head position changes and accompanied by characteristic nystagmus, also known as otolithiasis. Misdiagnosed as other diseases and delayed treatment, all three pairs of semicircular canals can occur, and can be divided into posterior semicircular canal (PC-BPPV), horizontal semicircular canal (HC-BP-PV), superior semicircular canal BPPV (SC-BPPV), and two Or two or more semicircular canals suffering from the four clinical types of mixed BPPV at the same time, which can be unilateral or bilateral; BPPV is a common disease in outpatient clinics, and it is also the main cause of vertigo. Manipulative reduction is the first choice for the treatment of benign positional vertigo. Different reset methods can be used for different types of benign positional vertigo. Clinically, the diagnosis can be made through the characteristic nystagmus induced by the corresponding body position displacement test. Otolith reset treatment has a unique curative effect, but many doctors even otolaryngology Doctors still don’t know much about benign paroxysmal positional vertigo and other vertigo diseases, and patients are easily misdiagnosed as cervical spondylosis, vertebrobasilar artery insufficiency, etc., which waste a lot of medical resources. Patients’ vertigo symptoms cannot be treated well relief
