Abstract:
PROBLEM TO BE SOLVED: To provide a newly-structured hemofiltration filter attachable to multiple storage containers with different-sized openings.SOLUTION: In a hemofiltration filter 10, a through-hole 18 covered by a hemofiltration membrane 28 is provided at a bottom wall 14 in a cup-like body 12, and a positioning projection 30 that projects downward and extends in a circumferential direction is formed on the bottom wall 14. As a positioning part to an opening 68 of a storage container 66 for filtered blood that has been filtered by the hemofiltration membrane 28, the hemofiltration filter 10 includes: a first positioning part that is formed by an inner peripheral surface 32 of the positioning projection 30 and an undersurface 38 of the bottom wall 14 on an inner peripheral side of the positioning projection 30; and a second positioning part that is formed by an outer peripheral surface 34 of the positioning projection 30 and an undersurface 40 of the bottom wall 14 on an outer peripheral side of the positioning projection 30.
