An experimental bile perfusion system for the in vitro bile flow phantom model. This system consists of a peristaltic pump, a bile reservoir, a bile reservoir warming container, five stent containing silicone tubes, and ten connecting silicone tubes. Three types of antireflux metal stents were inserted into the silicon tubes (15 stents in total)
