TOOL FOR INSPECTING/TREATING BENIGN PAROXYSMAL POSITIONAL VERTIGO

摘要

Provided is a tool for inspecting/treating benign paroxysmal positional vertigo, the tool enabling a user to recognize, in therapy pertaining to the physical position of the head, the positional relationship between a semicircular canal and an otolithic organ at each position of the head, the movement direction of an otolith, the position of the otolith, and nystagmus of a patient. A tool 2 for inspecting/treating benign paroxysmal positional vertigo, the tool 2 comprising an equilibrium function inspection device 4 mounted on the head of a patient, and a vestibular model 6 mounted on the equilibrium function inspection device 4. The vestibular model 6 includes three semicircular canals 20, and an otolithic organ 22 connected to the three semicircular canals 20, and moreover is formed from a transparent synthetic resin so as to be hollow. A liquid is sealed inside the vestibular model 6, and a plurality of otolithic models CP having a specific gravity higher than that of the liquid are accommodated therein so as to be capable of moving. Obstruction pieces 26a, 26b, 26c that allow passage of the liquid but obstruct passage of the otolithic models CP are positioned in enlarged sections 24a, 24b, 24c of the three semicircular canals 20.
