Abstract: The present invention relates to a fluid handling device which can prevent an inclination of a rotary member. The fluid handling device includes: a substrate; a circular first groove disposed on the substrate; a second groove connected to the first groove; a third groove connected to the first groove; a film joined to the substrate so as to cover the first groove, the second groove and the third groove; and a joining area where the film and the bottom of the first groove is joined, the joining area being disposed between a connecting portion of the second groove and a connecting portion of the third groove in the first groove. The surface of the film in the joining area is located closer to the bottom of the first groove than the surface of the film in an area joined to the substrate of the film.

Abstract: The present invention relates to a fluid handling device which can prevent an inclination of a rotary member. The fluid handling device includes a substrate; an arc-shaped groove having a central angle more than 180° disposed on the substrate; a first protrusion located between both ends of the groove in the same circumference as the arc-shaped groove; a second protrusion disposed in the groove; and a film joined on the substrate so as to cover the groove, the first protrusion and the second protrusion. The groove closed by the film functions as a rotary membrane pump.

Abstract: A liquid handling device includes a common channel, a first liquid inlet channel connected to the common channel, a first liquid outlet channel connected to the common channel, a second liquid inlet channel connected to the common channel, and a second liquid outlet channel connected to the common channel. The ratio between the volume between the confluence part of the first liquid inlet channel and the confluence part of the first liquid outlet channel, and the volume between the confluence part of the second liquid inlet channel and the confluence part of the second liquid outlet channel in the common channel is X:Y. The liquid handling device can mix first liquid and second liquid in a volume ratio of X:Y.

Abstract: The objective of the present invention is to provide a fluid handling device capable of easily isolating droplets. This objective is achieved by means of a fluid handling device which includes a first flow passage through the interior of which, when a fluid containing a droplet is delivered, the droplet can move, a first chamber which captures the droplet moving through the first flow passage, a second chamber into which the droplet captured by the first chamber can move, and a second flow passage providing communication between the first chamber and the second chamber, wherein the second flow passage is capable of selectively allowing the droplet to pass, or restricting passage of the droplet.

Abstract: This fluid handling device has a substrate, a film, and a sliding member. The substrate has first flow paths, second flow paths, and partition walls formed between one end of the first flow paths and one end of the second flow paths. The film includes a diaphragm, and is arranged above the substrate such that the diaphragm and the partition walls oppose one another. The sliding member has protrusions formed on the back surface thereof, and is arranged above the film with the back surface facing the film. By sliding on the film the sliding member is able switch alternately between a first state in which the protrusions are arranged so as not to oppose the partition walls, and the diaphragm is sandwiched therebetween, and a second state in which the protrusions are arranged opposing the partition walls, and the diaphragm is sandwiched therebetween.
