<P>PROBLEM TO BE SOLVED: To provide a medical valve capable of being connected to a male lure when the inner diameter of the tip of the male lure is small. <P>SOLUTION: The medical valve comprises a hollow housing 1 opening at both upper and lower ends and an elastic seal 2. The upper part inside the housing 1 is a connection port 10 into which the tip 30 of the male lure 29 is detachably inserted, and an expanding part 13 whose inner diameter becomes larger downward is formed under the connection port 10 inside the housing 1. The elastic seal 2 comprises a sealing part 20 and a film part 21. The sealing part 20 constitutes the upper part of the elastic seal 2 to be fitted into the connection port 10, and a liquid feeding passage opening upward and outward in the radial direction is formed on the upper end surface of the sealing part 20. The film part 21 is disposed below the sealing part 20, and is hollow with the outer and inner diameters becoming larger downward. The film part 21 opens at the lower end and closes an expanding part 13 as fitted into the expanding part 13 and closely attached to the inner surface of the expanding part 13. A through hole 27 is formed to pierce through the closely attached part of the film part 21 to the expanding part 13. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
