<p>[PROBLEM TO BE SOLVED] To provide a medical stopcock allowing the switching operation of plural branch-tubes easier. [SOLUTION] The medical stopcock main body 10 was comprised of: the chamber part 11, the inner surface of which is formed in the approximately spherically; the upstream branch-tube 12, the downstream branch-tube 13 and the merge-branch-tube 14 extending from the chamber part 11 respectively. Moreover, the valve body 20 was comprised of the valve main body 21 in the approximately spherical shape and the rod-shaped operating part 22. And, the guide hole 15 passing through from the inner surface of the chamber part 11 to the outside, the valve main body 21 was placed in the chamber part 11, and the rod-shaped operating part 22 was made to protrude from the guide hole 15 to the outside. Moreover, the horizontal flow passages 23 and the vertical flow passage 24 were formed on the valve main body 21, and the rod-shaped operating part 22 was moved along the guide hole 15 through the use of the horizontal flow passages 23 and the vertical flow passage 24 to allow the predetermined branch-tubes out of the upstream branch-tube 12, the downstream branch-tube 13 and the merge-branch-tube 14 to communicate with one another or to shut-off the communication.</p> |
