Blood Collection Device

Abstract

The blood collection device includes a holder configured to allow a blood collection tube to be installed, a blood collection portion configured to collect blood from a person from whom blood is to be collected into the blood collection tube, and a direction adjustment mechanism configured to adjust an orientation of the blood collection tube in the holder. The blood collection tube includes a bottomed cylindrical body portion having an opening in an upper portion, and a protruding portion formed by making a part of the opening in a circumferential direction protrude upward. The direction adjustment mechanism adjusts the orientation around a central axis of the blood collection tube such that a position of the protruding portion relative to the central axis of the blood collection tube falls within a predetermined range set in advance.
