Abstract: The present invention provides a method for coating an inner surface of a polyvinyl chloride medical tube containing a plasticizer with an antithrombogenic material composed of a specific (meth)acrylate copolymer. The simple method of the present invention is capable of evenly and efficiently coating an inner surface of a polyvinyl chloride medical tube with a sufficient amount of an antithrombogenic material without causing appearance deterioration or uneven coating due to elution of the plasticizer. The method is performed by passing through a tube a solution that is prepared by dissolving an antithrombogenic material in a solvent composed of water and at least one alcohol that is adjusted to dissolve the copolymer of the antithrombogenic material but does not dissolve the plasticizer, then subsequently passing water through the tube, and finally drying the tube.

Abstract: In a beam-connection member 9, the bottom surface side is a column-connection surface 14 and one side surface is a beam-mounting surface 16. In other words, the column-connection surface 14 and the beam-mounting surface 16 are formed to be substantially perpendicular. The column-connection surface 14 is the site of connection with a surface of the column. A depression 15 is formed on the column-connection surface 14. The depth of the depression 15 is preferably at least half of the main body thickness of the beam-connection member 9. Further, a notch 11 is formed across the width direction on the column-connection surface 14. The notch 11 is to avoid interference with the diaphragm. Near the notch 11, a rib 17 is provided in the depression 15 as necessary in the width direction. The rib 17 is for preventing deformation of the beam-connection member and for reinforcing the beam-connection member.
