摘要： A respiratory assistance device including a pair of prongs which are airways to be attached to a user's nose, and a blower which is connected to the pair of prongs and sends air to the user's nasal cavity via the prongs. The blower is placed on and is in contact with the user's mouth. The blower includes a housing including an intake port from which gas is taken in, a flow channel through which the air taken in via the intake port flows, and a discharge port which sends the air flowing through the flow channel toward the prongs, an impeller arranged in the housing so that its front side faces the intake port, and a partition member arranged on a rear side of the impeller so that a slit is formed along an inner periphery of the housing thereby partitioning the rear side into a space where the impeller is arranged.

摘要： A program for controlling a respiratory assistance device that is connected to a user's airway and regulates an airway pressure to assist ventilation has a plurality of different respiratory assistance modes. The respiratory assistance program causes a computer to realize an input reception function that receives an input of setting for a respiratory assistance mode during operation of an air blower that blows air to the user's airway, and a flow rate control function that, when the input reception function receives the input of setting, controls a flow rate from the air blower in reflection of a result of the input of setting. A respiratory assistance device in which a user can change setting to select a comfort pressure and flow rate is provided by using such a program.

摘要： 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.
