Abstract: A delivery blood storing member-equipped blood reservoir tank has a blood reservoir tank portion, and a delivery blood storing member that communicates with a blood outlet formed in the blood reservoir tank portion. The delivery blood storing member allows blood to flow out of an interior thereof when pressed from outside. The delivery blood storing member reserves amounts of blood in accordance with the height of liquid surface in the blood reservoir tank portion if the amount of blood in the blood reservoir tank portion becomes equal to or less than a predetermined value. The delivery blood storing member includes a body part that is formed from a hard material, and a flexible diaphragm whose peripheral end is fixed to the delivery blood storing member body part. The diaphragm produces substantially no self-restoring force against deformation.
