A medical connector includes: a housing comprising a male connector attachment/detachment part, the housing defining a liquid flow path; and a valve that is vertically movable with respect to the housing between a closed position for closing the male connector attachment/detachment part, and an open position in which a flow path in a male connector communicates with the liquid flow path, by the valve being pressed down from the closed position by the male connector against a biasing force. The valve comprises a head portion that closes the male connector attachment/detachment part when the valve is at the closed position, and a body portion that is connected to a bottom end of the head portion and receives the biasing force. A Young's modulus of the body portion is larger than a Young's modulus of the head portion.

A syringe adapter includes a housing having a first end and a second end positioned opposite the first end, with the housing including a connector body positioned at the first end of the housing and configured to be secured to a syringe barrel, a cannula positioned within the housing, with the cannula defining a transfer opening and a valve opening, a seal arrangement positioned within the housing and movable within the housing, and an aspiration assembly comprising an aspiration housing defining an aspiration opening, a filter received by the aspiration housing, and one-way valve received by the aspiration housing, where the valve opening of the cannula is positioned within the aspiration housing, and where air is configured to flow into the filter via the aspiration opening, into the one-way valve, and into the valve opening of the cannula.

A medical connector can include a body having a fluid path with an inlet port, an outlet port, a luer portion, and a post extending through a fluid path. An arm having a latch member is coupled to the body to engage a ridge or thread on an exterior surface of a reciprocal connector. The arm may also include an extension. When the connector is in an open position, the latch member restricts retraction of the reciprocal connector from the outlet port. A seal is coupled to the body and includes a flap extending across the outlet port or a bellows to compress along an axis. In a closed position, the post restricts flow through the luer portion. In an open position, the post permits flow through the luer portion.

A syringe adapter includes a housing having a first end and a second end positioned opposite the first end, with the housing including a connector body positioned at the first end of the housing and configured to be secured to a syringe barrel, a cannula positioned within the housing, with the cannula defining a transfer opening and a valve opening, a seal arrangement positioned within the housing and movable within the housing, and an aspiration assembly comprising an aspiration housing defining an aspiration opening, a filter received by the aspiration housing, and one-way valve received by the aspiration housing, where the valve opening of the cannula is positioned within the aspiration housing, and where air is configured to flow into the filter via the aspiration opening, into the one-way valve, and into the valve opening of the cannula.

A medical device includes a connector portion. The connector portion includes an inner cylinder connectable to another medical device having an elastic valve, a valve body against which the elastic valve is pressed from a distal end side due to connection of the inner cylinder and another medical device, and an outer cylinder disposed radially outside the inner cylinder, and the connector portion is configured to provide fluid communication between the connector portion and another medical device by moving the inner cylinder in an axial direction with respect to the outer cylinder in a state where the inner cylinder is connected with another medical device. The connector portion further includes an anchor that suppresses movement of the valve body with respect to the inner cylinder toward a proximal end.

A swabable valve (10) comprising a valve stem (100) that collapses into a valve body (12), said valve body (12) including a generally cylindrical reduced diameter section (18) having a generally circular rim, said valve stem (100) having a generally cylindrical reduced diameter portion (38) that extends fully into said cylindrical reduced diameter section (18) of said valve body (12), said cylindrical reduced diameter portion (38) including a through-slit (52) that opens when said valve stem (100) collapses into said valve body (12), said valve stem (100) having a concave curvilinear surface (102) that is substantially flush with said circular rim of said cylindrical reduced diameter section (18) of said valve body (12) when said valve stem (100) is not collapsed into said valve body (12); said concave curvilinear upper surface (102) of said valve stem (100) extending rim-to-rim within said cylindrical reduced diameter section (18) of said valve body (12).

A medical connector includes a medical device connection portion communication passage defined by a housing and a valve body to guide a fluid from a first medical device connection portion to a second medical device connection portion. In the medical connector, a male connector inserted into the a connector connection portion presses a head portion of the valve body while contracting and deforming a body portion, and a fluid is guided from the male connector connection portion to the medical device connection portion communication passage, through a gap formed between the head portion and the housing.

A medical connector includes a housing with a central axis, a hollow bore, and a narrowed passage. The connector further includes a rigid valve member configured to move along the axis of the connector as the connector moves between an open and closed configuration. The connector includes a resilient member coupled to the valve member and the housing.

A sterile tube connector for a fluid circuit system comprising a housing. A first opening is configured to receive a first length of tubing in communication with a first chamber. A second opening is configured for communicating with the first chamber when the tube connector is in an open configuration but not in a closed configuration. The second opening is configured to reversibly engage a third opening to form a second chamber. The third opening is configured for communicating with a second length of tubing. A first portion of the housing forming the first opening comprises a material at least partially permeable to a sterilization energy source for sterilizing contents of the second chamber.

A medical connector includes a body, a first connector defining a longitudinal axis extending from a first end of the first connector to a second end of the first connector and a second connector secured to the body and in fluid communication with the first connector. The first connector is secured to and rotatable relative to the body about the longitudinal axis. The first connector includes a valve member and is configured to be secured to a syringe barrel. The valve member of the first connector having a sealed position and an open position. The valve member of the first connector is configured to move from the sealed position to the open position when a syringe barrel is secured to the first connector.
