PROBLEM TO BE SOLVED: To provide a filter support unit of dialyzer configured to easily connect liquid outflow/inflow ports of a filter to a support unit.SOLUTION: A first outflow/inflow port 5A is protrudingly formed at one end in the axial direction of an outer peripheral surface of a filter 2, and a second outflow/inflow port 5B is protrudingly formed at the other end in the longitudinal direction, with the direction thereof matching that of the first outflow/inflow port 5A. A third outflow/inflow port 5C is longitudinally protrudingly formed at an end face of the other end side of the filter 2. Further, a first insertion port 11, a second insertion port 12, and a third insertion port 14 are provided at prescribed positions of a body part 7. An operator inserts the second outflow/inflow port 5B into the second insertion port 12 concurrently with a time when the operator holds the filter 2 and inserts the first outflow/inflow port 5A into the first insertion port 11, thereafter pulls down a cover 15, and inserts the third outflow/inflow port 5C into the lowered third insertion port 14.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2016,JPO&INPIT【課題】濾過器の液体流出入口を容易に支持装置と接続させることができる濾過器支持装置を提供する。【解決手段】濾過器2の外周面の軸方向の一端に第1流出入口5Aが突出させて形成されており、長手方向の他端に第2流出入口5Bが上記第1流出入口5Aと向きを揃えて突出させて形成されている。濾過器2の他端側の端面に第3流出入口5Cが長手方向に突出させて形成されている。他方、本体部7の所定箇所に、第1差込口11、第2差込口12及び第3差込口14が設けられている。作業者が濾過器2を把持して第1流出入口5Aを第1差込口11に差し込むと同時に第2流出入口5Bを第2差込口12に差し込み、その後にカバー15を引き下げて、下降された第3差込口14に第3流出入口5Cを差し込む。【選択図】図1
