<P>PROBLEM TO BE SOLVED: To provide a liquid coinfusion unit facilitating an operation for allowing an arbitrary tube to communicate or to be blocked, and preventing the backflow of a medicinal liquid. <P>SOLUTION: A liquid coinfusion unit main body 10 includes: a chamber part 11; an upstream tube 14 and a downstream tube 13 all of which extend from the chamber part 11; and a joining tube 12 arranged at the upper side of the chamber part 11. The body 10 internally comprises: a main flow passage for communication from the upstream tube 14 to the downstream tube 13; and a sub-flow passage for communicating or blocking between the joining tube 12 and the chamber part 11. Opening/closing parts 21a, 21b are arranged in the chamber part 11. Accordingly, the opening/closing parts 21a, 21b are closed in the chamber part 11 by pressuring pressure parts 22a, 22b, so as to block a part between the upstream tube 14 and the chamber part 11 in the main flow passage. <P>COPYRIGHT: (C)2008,JPO&INPIT |
