Abstract
A flow path cassette, a cell culturing kit, and a cell culturing system are provided, which are capable of increasing a degree of freedom in the layout of the flow paths. A flow path cassette, in which flow paths are aggregated, is equipped with a first cassette main body in which flow paths are formed between resin sheets and a second cassette main body in which flow paths are formed between resin sheets, and a frame in which these elements are accommodated. In the frame, the first cassette main body is accommodated in a first accommodation space formed in a first direction, and the second cassette main body is accommodated in a second accommodation space formed in a second direction on an opposite side from the first direction.

A flow path cassette in which flow paths are aggregated, the flow path cassette comprising:
- a first cassette main body in which a first group of flow paths is formed between a first pair of superimposed resin sheets;
- a second cassette main body in which a second group of flow paths is formed between a second pair of superimposed resin sheets;
- a plurality of connectors that communicate with the first group of flow paths and the second group of flow paths at outer edges of the first cassette main body and the second cassette main body;
- and
- a frame formed to be harder than the first cassette main body and the second cassette main body and configured to support the first cassette main body and the second cassette main body, the frame comprising:
- a flat plate-shaped cover member disposed between the first cassette main body and the second cassette main body;
- first side portions that project from outer edges of the cover member in a first direction perpendicular to the cover member;
- second side portions that project from the outer edges of the cover member in a second direction opposite to the first direction;
- and
- engaging portions disposed on the first side portions and the second side portions and configured to engage with the plurality of connectors,
- wherein the first cassette main body is accommodated in a first accommodation space defined in a first recessed shape formed by the first side portions and the cover member, and wherein the second cassette main body is accommodated in a second accommodation space defined in a second recessed shape formed by the second side portions and the cover member.
