Abstract

Official abstract text for this publication.

A fluid handling device includes a sample channel configured to carry a sample; a dispersion medium channel configured to carry dispersion medium; a dispersion liquid generation part connected to the sample channel and the dispersion medium channel, and configured to generate dispersion liquid by dividing the sample by the dispersion medium, the dispersion liquid being liquid in which droplets of the sample are dispersed in the dispersion medium; and a dispersion liquid channel connected to the dispersion liquid generation part. The dispersion liquid generation part includes a protrusion.

First claim

Opening claim text (preview).

The invention claimed is: 1. A fluid handling device comprising: a sample channel configured to carry a sample; a dispersion medium channel configured to carry dispersion medium; a dispersion liquid generation part connected to the sample channel and the dispersion medium channel, and configured to generate dispersion liquid by dividing the sample by the dispersion medium the dispersion liquid being liquid in which droplets of the sample are dispersed in the dispersion medium; and a dispersion liquid channel connected to the dispersion liquid generation part, wherein the dispersion liquid generation part includes a protrusion, and wherein in plan view of the fluid handling device, at least a part of the protrusion is located on a line connecting a center of the sample channel in a width direction at a connecting part of the sample channel and the dispersion liquid generation part, and a center of the dispersion liquid channel in the width direction at a connecting part of the dispersion liquid channel and the dispersion liquid generation part. 2. The fluid handling device according to claim 1 , wherein the protrusion is line-symmetric with respect to the line. 3. A fluid handling device comprising: a sample channel configured to carry a sample; a dispersion medium channel configured to carry dispersion medium; a dispersion liquid generation part connected to the sample channel and the dispersion medium channel, and configured to generate dispersion liquid by dividing the sample by the dispersion medium, the dispersion liquid being liquid in which droplets of the sample are dispersed in the dispersion medium; and a dispersion liquid channel connected to the dispersion liquid generation part, wherein the dispersion liquid generation part includes a protrusion, and wherein the protrusion includes a tapered portion whose width decreases from a sample channel side toward a dispersion liquid channel side. 4. The fluid handling device according to claim 1 , wherein the protrusion is a columnar member or a conical member.
