Abstract: A sensor cover includes a cover film having an upper cover film and a lower cover film that are joined to each other at least at respective one sides thereof, and the cover film is shaped like a bag and configured to accommodate a temperature sensor when in use. The sensor cover also includes a self-adhesive member that has adhesiveness and is disposed on an outside surface of the lower cover film. The sensor cover further includes a sensor mounting member that is disposed on an inside surface of the lower cover film and configured to attach the temperature sensor closely to the lower cover film. The sensor cover further includes a sealing member that closes and seals an edge portion of an opening of the cover film.

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.

Abstract: A pressure device includes a bag-shaped compression bag, a cover member installed at a first surface portion of the compression bag, an accommodating space defined by the cover member and the compression bag, a piezoelectric pump that flows air into the compression bag, and a casing that accommodates the piezoelectric pump. The compression bag has a bag opening formed at a second surface portion different from the first surface portion and connecting an internal space of the compression bag and an outside to each other. The casing has a casing opening. The casing (31) is fixed to the second surface portion of the compression bag while being in contact with the second surface portion to directly connect the bag opening and the casing opening to each other in an overlapping manner.

Abstract: A fluid control device includes piezoelectric pumps and a substrate. The substrate includes dielectric base members. Each of the dielectric base members has a recess and a through-hole. Each of the dielectric base members is laminated such that the recesses of the dielectric base members partially overlap and communicate with each other. A portion of the recesses not overlapping with the dielectric base member serve as a first opening and a second opening, respectively, to the outside. The first opening and the second opening open in opposite directions in the lamination direction. The first opening and the second opening have shapes that may be fit to each other. The piezoelectric pump is on the dielectric base member to communicate with the through-hole, and the piezoelectric pump is on the dielectric base member to communicate with the through-hole.
