PROBLEM TO BE SOLVED: To filtrate blood simply and speedily and to enable the intact dripping of a filtrate of plasma, etc., onto an analyzing device by housing hemofiltration material at the lower part of a tubular container with a bottom, providing a blood receiving space for filtration over the hemofiltration material, and providing a dripping opening of blood filtrates at the bottom surface of the container. SOLUTION: The tubular container 1 with a bottom is formed of polypropylene and has a cylindrical shape, and a dripping opening in the shape of a short tube is protruded from and formed at the center of the bottom surface of the tubular container 1. The inner diameter of the tubular container 1 is, for example, 4 mmϕ, and the depth from its upper edge to the bottom surface is 15 mm. The diameter (inner diameter) of the dripping opening is 1 mmϕ, and the height of its protrusion below is 5 mm. A polysulfone film with a thickness of, for example, 170μm and a glass fiber filter paper with a thickness of 1 mm overlaid on other are inserted in the container 1. The total thickness of the hemofiltration material is, for example, 7 mm, the blood receiving space for filtration is provided over the material leaving a space with a depth of 8 mm, and blood 6 is poured. A pressing device 7 is mounted onto the dripping device to filtrate the blood 6. The pressing device 7 is made of rubber and is in an umbrella shape with an opening at the center. Filtration is performed by covering the upper part opening of the container 1 with the pressing device 7, supporting the vicinity of the bottom edge of the container 1, and closing the center opening 8 pressing with the thumb. |
