PROBLEM TO BE SOLVED: To provide an educational instrument for benign paroxysmal positional vertigo (BPPV) that is used to enable a patient subjected to cephalic presentation treatment to easily understand the details of the cephalic presentation treatment prior to the treatment, and enables physiotherapists or young doctors to easily image the positional relation between a posterior semicircular canal and a utricle at each cephalic presentation and the position of a floating otolith.SOLUTION: An educational instrument for treatment of BPPV is an actual model of a head having built-in a model of three semicircular canals model with movable otolith. In the instrument, a 2-20 times enlarged model of the human three semicircular canals model and the actual model of a head are a 1.0-1.7 times enlarged model of a human head. The instrument has a structure in which a liquid and a plurality of otolithic models having a specific gravity larger than the liquid are enclosed inside a hollow annular member made of a transparent resin and provided with an otolith engaging portion at a position corresponding to that of the cupula of the three semicircular canals. The otolith engaging portion passes through the liquid, but does not pass through the otolithic models.COPYRIGHT: (C)2014,JPO&INPIT【課題】頭位治療に先んじて、頭位治療の施術を受ける患者に治療内容の指示を容易に理解させるため、そして理学療法士並びに若手の医師に各頭位での後半規管と卵形嚢の位置関係や浮遊耳石の位置を容易にイメージし易くさせるために用いられる、良性発作性頭位めまい症の治療教育用器具を提供する。【解決手段】可動耳石付三半規管モデルを内蔵する頭部実態模型であって、前記三半規管モデルが、人体における三半規管の2~20倍拡大模型、及び前記頭部実態模型が、人体における頭部の1.0~1.7倍拡大模型であり、かつ該三半規管のクプラに対応する位置に耳石係止部を配設した透明樹脂からなる中空環状体の内部に、液体と、該液体の比重よりも大きな比重をもつ複数の耳石模型とを封入した構造を有し、かつ該耳石係止部が、前記液体は通過するが、耳石模型は通過しないことを特徴とする、良性発作性頭位めまい症の治療教育用器具である。【選択図】図1
