Abstract: A blower is disposed in a main flow passage of a main unit of a CPAP device. An upstream flow passage connected upstream of the main flow passage is in a base unit. A sealing member secured to the base unit of the CPAP device has an annular shape surrounding a second outlet from outside. The shape of an opening of the sealing member at a distal end edge in the extending direction is a shape surrounding a first inlet from outside. The dimension of the sealing member in the extending direction is greater than the dimension of the sealing member in the thickness direction. When the main unit is attached to the base unit, the dimension of the sealing member in the extending direction is greater than a minimum distance from a proximal end of the sealing member in the extending direction to the main unit.

Abstract: A fluid control device 1 includes a casing 10 configured to house a cylindrical infusion tube 100 and a droplet detecting section 60 configured to detect the amount of droplets dripping from a nozzle 124 in the infusion tube 100 housed in the casing 10. The infusion tube 100 includes a flange protruding outward. The casing 10 includes an engagement member 30. The engagement member 30 includes a flange configured to engage with the flange in the infusion tube 100 in a direction along the longitudinal direction of the infusion tube 100 and fix the infusion tube and a fixation surface configured to fix the infusion tube 100 in a direction orthogonal to the longitudinal direction of the infusion tube 100.

Abstract: The present disclosure relates to a continuous positive airway pressure (CPAP) device which sends, into an airway of a user, air sucked into the device. A body unit as a first unit has a cylindrical first lead-out portion through which air circulates. A base unit as a second unit has a third introduction portion to which the first lead-out portion is to be connected. A body-side terminal is provided as a first terminal with conductivity at the first lead-out portion of the body unit. A base-side terminal is provided as a second terminal with conductivity at the third introduction portion of the base unit. The body-side terminal is in contact with the base-side terminal while the body unit is attached to the base unit.

Abstract: The CPAP device includes a main unit and a second unit to be attached to or detached from the main unit. The main unit includes a first housing having a first lead-out part, an air blower for leading out air from the first lead-out part, and a first electrical connection part provided on the first housing. The second unit includes a second housing having a second lead-in part and a second lead-out part, a humidifier which humidifies air led therein from the second lead-in part, and a second electrical connection part to be connected to the first electrical connection part. The first lead-out part and the second lead-in part are configured to guide, with a connection between them, the first electrical connection part and the second electrical connection part to a position where they are connectable to each other.
