Abstract
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.
