Title (EN) OPENING/CLOSING DEVICE AND RESPIRATORY ASSISTANCE DEVICE
(FR) DISPOSITIF D'OUVERTURE/FERMETURE ET APPAREIL D'ASSISTANCE RESPIRATOIRE
(JA) 開閉具及び呼吸補助装置
Abstract:
(EN) A respiratory assistance device (10) is provided with: a mask (13) having an exhalation hole (13a); an exhalation valve (15) provided to the mask (13) and opening and closing the exhalation hole (13a); and a control unit (17) for controlling the entire device in an integrated manner. An opening/closing device is formed by the mask (13) and the exhalation valve (15). The exhalation valve (15) can be deformed by the deformation of a piezo element (15a). The exhalation valve (15) is disposed on the inner surface (13f) of the mask (13) in such a manner that the direction of deformation of the exhalation valve (15), which is the thickness direction of the exhalation valve(15), extends along the inner surface (13f) of the mask (13) and in such a manner that the deformation of the exhalation valve (15) causes a side surface (15m) to slide on the inner surface (13f).
(FR) Cette invention concerne un appareil d'assistance respiratoire (10) comprenant : un masque (13) pourvu d'un orifice d'expiration (13a); un clapet d'expiration (15) équipant le masque (13) et ouvrant et fermant l'orifice d'expiration (13a); et une unité de commande (17) pour commander l'ensemble de l'appareil de manière intégrée. Un dispositif d'ouverture/fermeture est formé par le masque (13) et le clapet d'expiration (15). Le clapet d'expiration (15) peut être déformé par déformation d'un élément piézoélectrique (15a). Le clapet d'expiration (15) est monté sur la surface intérieure (13f) du masque (13) de façon que le sens de la déformation du clapet d'expiration (15), qui est le sens de l'épaisseur dudit clapet d'expiration (15), s'étende le long de la surface intérieure (13f) du masque (13) et de façon que la déformation du clapet d'expiration (15) fasse coulisser une surface latérale (15m) sur la surface intérieure (13f).
(JA) 呼吸補助装置(10)は、呼気孔(13a)を有するマスク(13)と、マスク(13)に設けられ呼気孔(13a)の開閉を行う呼気弁(15)と、装置全体を統括的に制御する制御ユニット(17とを備えている。そして、マスク(13)と呼気弁(15)とによって開閉具が 形成される。呼気弁(15)は、ピエゾ素子(15a)の変形によって変形自在となる。呼気弁(15)は、自身の変形方向、すなわち自身の厚み方向がマスク(13)の内面(13f)に沿うように、かつ、自身の変形により側面(15m)が内面(13f)に摺動するように、内面(13f)に配される。
