A male connector () includes a first fitting structure () on an inner circumferential surface of a hood () surrounding a male member (). A female connector () includes a rotating cylinder () rotatably provided on a female connector main body () that includes a partition member () made of an elastic material. A second fitting structure () is provided on an outer circumferential surface of the rotating cylinder. When the male connector is connected to the female connector, the male member passes through a slit () of the partition member, the female connector is inserted into the hood, and the first fitting structure fits to the second fitting structure.

Connecting device

A head portion () is provided at one end of an outer circumferential wall () capable of elastic compression deformation. The outer circumferential wall includes multiple compression units () that undergo deformation due to compression force in a central axis () direction. Letting N be an integer of 2 or more, the compression units each have at least either N thick portions () or N thin portions () formed at equiangular intervals with respect to the central axis such that the thickness periodically changes in the circumferential direction. The phase with respect to the central axis of the periodic change in thickness is shifted between two compression units that are neighboring in the central axis direction.

Cover for male member

A medical port includes a disc-shaped valvein which an insertion hole is formed in a central portion, a base seatthat supports the valve from a lower surface side, and a coverthat has a fitting hole exposing an upper surface of the central portion of the valve and covers at least a peripheral edge of the valve from the upper surface side, the fitting hole being formed so that when an inserting body has been inserted into the insertion hole, a fit between the inserting body and the fitting hole can cause the inserting body to be locked against the cover. An annular protrusionis formed in the valve, the annular protrusion being continuous in the circumferential direction, and formed in the valveso that in the state in which the inserting body is locked against the cover, the annular protrusion is in contact with an outer circumferential surface of a leading end portion of the inserting body.

Medical port

A male member () includes a tubular member () and a cover () covering at least a tip () of the tubular member. A lateral hole () that communicates with a flow path () is formed in an outer peripheral surface of the tubular member. The cover includes an outer peripheral wall () that can be deformed elastically by compression and a head part () that is provided at one end of the outer peripheral wall. The head part includes an interior cavity () into which the tubular member is inserted, and a slit () is formed in an innermost part () of the interior cavity. In a state where the outer peripheral wall is not deformed by compression, an inner peripheral surface of the interior cavity contacts closely with the outer peripheral surface of the tubular member so as to block the lateral hole, and the tip of the tubular member and the innermost part of the interior cavity are spaced apart from each other. Thereby, it is possible to reduce an amount of a liquid substance adhering to outer surfaces of the cover and a female member after separation from the female member.
