<P>PROBLEM TO BE SOLVED: To provide a medical port configured to suppress a rip in a valve. <P>SOLUTION: The medical port includes the disc-shaped valve 1 having an insertion hole 1f formed in a center part, a base seat 7 for supporting the circumferential edge of the valve from the lower surface side, and a cover 2 which has a fitting hole to expose the upper surface of the center part of the valve and covers at least the circumferential edge of the valve from the upper surface side. The fitting hole is formed to engage an insertion body with the cover by fitting the insertion body in the fitting hole when the insertion body is inserted into the insertion hole. In the lower surface of the valve, protruding parts for suppressing a rip of the insertion hole are each formed in the vicinities of both ends in the longitudinal direction of the insertion hole on a straight line in the same direction as the longitudinal direction of the insertion hole. In the lower surface of the valve 1, the shortest distance between the respective protruding parts and the insertion hole 1f is more than 0 mm and 0.5 mm or less, and the maximum height of the respective protruding parts is between 0.2 mm and 0.5 mm. <P>COPYRIGHT: (C)2010,JPO&INPIT |
