<P>PROBLEM TO BE SOLVED: To provide a medical stopcock which prevents the retention of a liquid and air bubbles for sufficiently higher workability by decreasing a dead space of a space within a branch passage. <P>SOLUTION: A first groove part 21 as a first communication passage and a second groove part 22 as a second communication passage are formed in a valve 20 while a partition 20a is provided to shut down the communication between the first and second groove parts 21 and 22 within the valve 20. This allows the flow of the main passage to reach a third branch passage 13a as a mixing path, thereby achieving the decrease in the dead space in the third branch passage 13a. <P>COPYRIGHT: (C)2007,JPO&INPIT |
