PROBLEM TO BE SOLVED: To sufficiently ensure a connection holding force and require no strong force or special skill in operation of releasing a connection.SOLUTION: An artificial lung 2 is supported by a blood storage tank 1 through a connection member 20. A fitting inner cylinder part of the artificial lung fits within a second fitting part 23 of the connection member and has a plurality of slide projections 12. The connection member comprises engaging grooves 8, 24 corresponding to the slide projections and a lock member 25. The engaging grooves include a vertical groove in a shaft direction of the second fitting part and a lateral groove in a circumferential direction. With a relative displacement of the second fitting part and fitting inner cylinder part, the slide projections enter the vertical groove from a lower end and slide in the lateral groove. The lock member includes a catch protruding inward at a lower portion of a fulcrum and an operation lever part extending upward from the fulcrum. The catch engages with the slide projections at a prescribed position of the lateral groove and prevents a rotation displacement to a start edge side of the lateral groove. By pressing and rotating the operation lever part, the catch displaces to a radial direction, and an engagement with the slide projections is released. |
