Title
(EN) OPENING AND CLOSING DEVICE AND RESPIRATORY ASSISTANCE DEVICE
(FR) DISPOSITIF D'OUVERTURE/FERMETURE ET APPAREIL D'ASSISTANCE RESPIRATOIRE
Abstract
(EN)

A respiratory assistance device 10 includes: a mask 13
having an expiratory hole 13a; an expiratory valve 15 provided
in the mask 13, for opening and closing the expiratory hole
13a; and a control unit 17 for performing overall control on
the entire device. The mask 13 and the expiratory valve 15
together form an opening and closing device. The expiratory
valve 15 is deformable by deformation of a piezo element 15a.
The expiratory valve 15 is disposed on an inner surface 13f so
that a deformation direction thereof, i.e., a thickness
direction thereof, extends along the inner surface 13f of the
mask 13 and a side surface 15m slides along the inner surface
13f by the deformation thereof.
