摘要： A gas control device includes a pump, a valve, a cuff, and a controller. The valve includes a first plate having a first vent hole and a first vent hole, a channel forming plate having an exhaust hole and an exhaust channel, a second plate having a second vent hole, and an edge separation plate. A manchette rubber tube in the cuff is joined to the periphery of the second vent hole in the second plate by an adhesive, and thus the valve is connected to the cuff. The exhaust hole is opened to the atmosphere. The pump includes a pump housing having a discharge hole and a discharge hole. The upper surface of the pump housing is joined to the bottom surface of the edge separation plate.

摘要： A pump includes a housing, a first vibrating body, a second vibrating body, and a peripheral wall portion that define a pump chamber, and a driving body. The housing has a first wall portion opposed to the first vibrating body and a second wall portion. The first wall portion includes a first concave portion that opens toward the first vibrating body and opposed to a central portion of the first vibrating body and a first circumferential portion adjacent to the first concave portion. A first chamber includes a first wide portion defined by the first concave portion and the first vibrating body, and a first narrow portion defined by the first circumferential portion and the first vibrating body. The first narrow portion overlaps with at least part of the first vibrating body.

摘要： An inhalation device includes a nozzle, a separator, a housing, a battery portion, a circuit board, and a piezoelectric blower. The piezoelectric blower has a suction hole that opens near the center of an upper surface of the piezoelectric blower and a discharge hole that opens at the center of a bottom surface of the piezoelectric blower. The piezoelectric blower is mounted on a first main surface of the circuit board on the side of an upper housing. The circuit board applies a drive voltage to the piezoelectric blower to drive the piezoelectric blower. The circuit board has a through-hole facing the discharge hole. The through-hole overlaps the discharge hole, out of the suction hole and the discharge hole, when the first main surface of the circuit board is viewed from a front side.

摘要： A fluid control device (1) includes a case (21) including a case top plate, a case side plate, and a case bottom plate and having an internal space (59) and a cavity, a pump (11) provided at a position at which the pump (11) divides the internal space (59) into a bottom-plate-side region and a top-plate-side region, the pump (11) being configured to generate a flow of a fluid between the bottom-plate-side region and the top-plate-side region and control the flow direction of the fluid, and a fixing member (31) that fixes the case (21) in place. The case (21) is mounted on the fixing member (31) by using the case top plate or the case bottom plate as a mounting surface (B).

摘要： A valve includes a first valve housing, a second valve housing, a diaphragm, a first fixing part, and a second fixing part. The diaphragm defines an upstream valve chamber together with the first valve housing. The diaphragm defines a downstream valve chamber together with the second valve housing. The diaphragm is movable between a first position in which the diaphragm blocks communication between the upstream valve chamber and the downstream valve chamber, and a second position in which the diaphragm allows communication between the upstream valve chamber and the downstream valve chamber. When in its second position, the diaphragm makes contact with the inlet of the second discharge channel or the wall surface of the downstream valve chamber to seal between the second discharge channel and the first discharge channel, and when in its first position, the diaphragm allows communication between the first discharge channel and the second discharge channel.

摘要： Provided is a suction device that can suppress sound and vibration during use. A suction device includes a flow-passage forming section (1) having a suction port (20) from which fluid is sucked, a discharge port (29) from which the fluid is discharged, and a flow passage (2) which is sealed from an outside except at the suction port (20) and the discharge port (29) and through which the fluid flows, and a piezoelectric driving part (33) that generates a flow of the fluid in the flow passage (2). The piezoelectric driving part (33) includes a diaphragm (37) and a piezoelectric element (34) as a moving part that transmits driving force to the fluid. The moving part is entirely disposed inside the flow passage (2).
