Stopcock Valve

A medical stopcock comprising a medical stopcock main body including:

• a chamber part having an open space part the inner surface of which is formed approximately spherically and a guide hole located at a predetermined position of said inner surface through to the outside,
• plural branch-tubes each of which having a flow passage spaced from the outer peripheral surface of said chamber part and extending outward respectively to communicate with inside said chamber part,
• a valve main body comprising an approximately spherical body installed in the said chamber part and provided with flow passages formed at a predetermined position thereon and capable of allowing predetermined branch-tubes out of said plural branch-tubes to communicate with one another through the use of said flow passages or of shutting-off the communication by rotationally moving along the inner surface of said chamber part and
• a rod-shaped operating part allowing the flow passages of said valve main body to communicate with predetermined branch-tubes out of said plural branch-tubes, or shutting-off the communication by passing through said guide hole from the outer peripheral surface of said valve main body and extending outward and by moving along said guide hole.
