PROBLEM TO BE SOLVED: To provide a medical treatment port little deteriorating sealing performance even if repeatedly used, and to provide a cell-storing container having the medical treatment ports.SOLUTION: A medical treatment port 1 includes an outer cylindrical member 2 having an outer cylindrical portion 22 in which an outer cylindrical hollow portion 21 whose one end portion and other end portion are opened is formed, an inner cylindrical member 3 which is slidably, to the outer cylindrical member 2, inserted from one end portion 22a of the outer cylindrical member 2 into the outer cylindrical hollow portion 21 and in which an inner cylindrical hollow portion 31 whose one end portion 3a and other end portion 3b are opened is formed, an opening or closing mechanism which stops the distribution of a fluid in the inner cylindrical hollow portion 31 at an insertion position where the inner cylindrical member 3 is slid into the outer cylindrical member 2 in an insertion direction, and permits the distribution of the fluid in the inner cylindrical hollow portion 31 at a pullout position where the inner cylindrical member 3 is slid from the insertion position in a counter-insertion direction at a prescribed distance, and a fluid-tight portion 4 for holding a fluid-tight state between the inner circumferential surface of the outer cylindrical member 2 and the outer circumferential surface of the inner cylindrical member 3. |
