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: 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: A pump unit (100) includes a plurality of piezoelectric pumps (1), a flow path-defining member (50), and a heat-dissipating part (60). The plurality of piezoelectric pumps (1) each include a first flow path for sucking and discharging of fluid. The flow path-defining member (50) includes a second flow path for connection to the first flow paths in the plurality of piezoelectric pumps (1). Heat generated in the plurality of piezoelectric pumps (1) is dissipated through the heat-dissipating part (60). The heat-dissipating part (60) is disposed between the flow path-defining member (50) and each of the plurality of piezoelectric pumps (1). The heat-dissipating part (60) has through-holes through which the first flow paths are connected to the second flow path.
