<p>A fluid passage valve (2) selectively opens and and closes a fluid passage port defined in a bottom of a chamber (4) which contains a fluid to be transfused into a patient's vein. The fluid passage valve (2) has a valve member (52) movable toward and away from the fluid passage port (34) to open and close the fluid passage port (34), and a valve member casing (54) which houses the valve member (52). The valve member casing (54) has a plurality of limbs (58) which are progressively spread outwardly away from each other in a direction toward the bottom of the chamber, so that the valve member (52) will not be caught by the limbs (58) when the valve member (52) is lowered to close the fluid passage port (34).</p> |
