Document Type and Number:
WIPO Patent Application WO/2017/056142
Kind Code:
A1
Abstract:
Provided are a flow passage module which can achieve complete liquid substitution in a circulating flow passage with a simple structure, and a cell culture apparatus using said flow passage module. A flow passage module 1 comprises: a flexible branching section 2 which is provided with a first branching flow passage 2a connected with an inflow passage 4 for a fluid, a second branching flow passage 2b connected with an outflow passage 5, a third branching flow passage 2c connected with an entry-side end part 6a of a circulating flow passage 6, and a fourth branching flow passage 2d connected with an exit-side end part 6b of the circulating flow passage 6, and which enables the branching flow passages to be communicated with each other; and a communication state switching part 3 which has opening/closing members (3a, 3b) for closing and opening the desired branching flow passage from among the plurality of branching flow passages, and which switches between a first communication state in which the third branching flow passage 2c and the fourth branching flow passage 2d are communicated and a second communication state in which the first branching flow passage 2a and the third branching flow passage 2c are communicated with each other and the second branching flow passage 2b and the fourth branching flow passage 2d are communicated with each other, by moving the opening/closing members in one direction and pressing the desired branching flow passage closed.
