PROBLEM TO BE SOLVED: To provide caps 12A, 12B for a blood apparatus in which a weld line is not formed in a blood contact region 31, and a blood apparatus 10.SOLUTION: Caps 12A, 12B for a blood apparatus are attachable to an opening of a cylindrical body 11 of a blood apparatus and is obtained by subjecting a thermoplastic resin to injection molding. The cap for a blood apparatus includes a cylindrical side part 21, a lid part 22 which closes an opening in one direction 101A in an axial direction 101 of the side part 21 and has a through hole 25 in the axial direction 101; and a nozzle part 23 which is provided on the lid part 22 and makes an inner space communicate the through hole 25 of the lid part 22. In an attached state where the caps 12A, 12B for a blood apparatus are attached to the opening of the body 11, in the caps 12A, 12B for a blood apparatus, a weld line is not formed in a blood contact region 31 with which blood circulating in the body 11 is brought into contact on an inner surface of the lid part 22.SELECTED DRAWING: Figure 2 |
