Abstract: A channel chip having a channel for running a fluid that is opened and closed by sliding on a film a sliding member slidable on the film while contacting with the film, the channel chip comprising: a substrate including a first channel, a second channel and a partition wall formed between the first channel and the second channel; a film including a diaphragm having a substantially spherical crown shape, the film being disposed on the substrate so that the diaphragm faces the partition wall; and a positioning section for holding the sliding member in such a way that the sliding member is slidable on the film while the positioning section positions the sliding member, the positioning section being disposed on the film.

Abstract: A fluid handling device includes: a substrate including a first surface and a second surface which are opposite to each other, wherein a first recess which allows fluid to flow therethrough is formed on the first surface; a film including a third surface and a fourth surface which are opposite to each other, wherein at least a pair of second recesses is formed on the third surface; and at least a pair of electrodes whose shape is defined by the second recesses, the electrodes being disposed in the second recesses and configured to apply an electric field to an inside of the first recess, the film being joined to the substrate such that the first surface and the fourth surface face each other.

Abstract: A fluid handling device, comprising: a substrate including a first channel, a second channel and a partition wall formed between the first channel and the second channel; a film including a diaphragm, the film being disposed on the substrate so that the diaphragm faces the partition wall; and a sliding member slidable on the film while contacting with the film, the sliding member including a protrusion formed on an underside thereof, and the sliding member being disposed on the film with the underside facing the film, wherein: the sliding member is capable of switching between a first state and a second state by sliding on the film, wherein the protrusion is positioned so as not to face the partition wall with the diaphragm therebetween in the first state, and the protrusion is positioned so as to face the partition wall with the diaphragm therebetween in the second state.

Abstract: A micro fluid chip includes a first chip and a second chip. The first chip includes a first substrate having a fluid channel and a partition wall, and a first film made of resin. The second chip includes a second substrate having a recess, and a second film made of elastomer. The second film has an elastic modulus higher than that of the first film. The first chip and the second chip are stacked in such a manner that the partition wall and the recess face each other with the first film and the second film therebetween. By setting the inner side of the recess to a negative pressure, a gap is formed between the first film and the partition wall, and thus a fluid channel is opened.
Abstract translation: 微流体芯片包括第一芯片和第二芯片。 第一芯片包括具有流体通道和分隔壁的第一基板和由树脂制成的第一薄膜。 第二芯片包括具有凹部的第二基板和由弹性体制成的第二薄膜。 第二膜具有比第一膜高的弹性模量。 第一芯片和第二芯片以这样的方式堆叠，使得分隔壁和凹部彼此面对，其中第一膜和第二膜彼此面对。 通过将凹部的内侧设定为负压，在第一膜和分隔壁之间形成间隙，从而打开流体流路。
