A sealable access stopcock 1 includes a valve body (12) having a switching part formed in a valve shaft thereof for switching from one flow passage to another; and a main body (2) having an internal chamber (3) in which the valve shaft of the valve body (12) is rotatably fitted, and a plurality of tributary tubes (5, 6, 7) each having a lumen (5a, 6a, 7a) extending therethrough, the lumen (5a, 6a, 7a) opening on a side wall of the internal chamber (3); the valve body (12) being rotated to selectively bring the lumens (5a, 6a, 7a) into communication with one another through the switching part and thereby switch flow of an infusion fluid from one flow passage to another. The sealable access stopcock 1 is characterized in that a switching channel (16) in the form of an arcuate groove is formed in the switching part of the valve shaft to extend along the circumferential surface thereof. <IMAGE> |
