<P>PROBLEM TO BE SOLVED: To provide a liquid coinfusion unit inside which liquid and air are unlikely to accumulate. <P>SOLUTION: A liquid coinfusion unit A comprises a chamber part 11, a main upstream branch pipe 12, a downstream branch pipe 13, a supplementary upstream branch pipe, and a stopcock 30 which can allow communication/block the area between the chamber part 11 and main upstream branch pipe 12, and the area between the chamber part 11 and downstream branch pipe 13, respectively. The portion of the liquid flow channel inside the chamber part 11, which runs from the main upstream branch pipe 12 toward the downstream branch pipe 13, comprises a bypass flow channel which extends from the direction of advance of the liquid from the main upstream branch pipe 12 toward the chamber part 11 to one side which is substantially orthogonal to the direction of advance, after which it extends in the direction of advance of the liquid from the chamber part 11 toward the downstream branch pipe 13. In addition, an inclined surface 17, whereof the upstream portion is positioned on the one side and the downstream portion is positioned further towards the side in the direction of advance of the liquid, from the chamber part 11 towards the downstream branch pipe 13 than that one side, is formed in the bypass flow channel. <P>COPYRIGHT: (C)2010,JPO&INPIT |
