Title: (EN) Blood reservoir
Abstract: front page image
(EN)

A blood reservoir serves to suppress generation of air bubbles in blood in an extracorporeal blood circulation circuit. The blood reservoir includes a blood storage chamber for temporarily storing the blood, the blood storage chamber having blood inlet and outlet ports, and a fluid-permeable blood spouting inhibitor disposed over the blood inlet port. Since the blood flows into the blood storage chamber through the blood spouting inhibitor, the blood is prevented from being spouted into the blood reservoir, so that air bubbles are prevented from being generated in the blood.
