Luer receiver and method for fluid transfer

A luer receiver for connecting with a luer lock connector having a male luer tip and a surrounding female threaded end, the receiver comprising:

• a housing having an inner wall, a proximal end, a distal end, and a bore extending from said proximal end towards distal end, said proximal end of said housing being sized to be received into said luer lock connector,
• a septum defining a longitudinal axis and mounted at least partially within said bore adjacent said proximal end, said septum having an upper face and a slit extending from said face at least partially through said septum, said septum being sized and configured to receive at least a portion of said male luer end into said septum through said face and through at least a portion of said slit, at least a portion of said septum being displaced lateral to said longitudinal axis by said luer tip when said luer tip is advanced into said septum to define a displaced septum portion,
• at least one cavity defined at a periphery of said septum for receiving at least a portion of said displaced septum portion upon insertion of said tip into said septum, said cavity having a distal end, and
• a seal being provided adjacent said distal end of said cavity for sealing said cavity.

A method for the transfer of fluid, comprising the steps of:

• providing a medical luer receiver, including:
• a housing having a proximal portion, a central portion, and a distal portion, and a bore extending axially through said proximal and said central portions into said distal portion;
• and
• a septum formed at least in part from an elastomeric material and having an outer face, a proximal portion, an extension portion, and a central slit defined at least partially therethrough, said septum proximal portion including an upper portion having a width greater than a width of said extension portion, a proximal end of said housing comprising a substantially continuous ring structure defining a platform, said upper portion of said septum being seated on said platform;
• pressing a male luer tip of another medical device against the outer face of the septum, the ring structure holding the upper portion of the septum in position while the luer tip penetrates into the slit and into the septum;
• deflecting walls of said slit laterally such that opposing inner faces of said walls directly press against an outer wall of said cannula after the luer tip has been advanced into the slit, and
• flowing liquid through the luer tip and into said distal portion of said housing.

A method of transferring medical liquid between a medical liquid storage container and a chamber using a luer connector, the connector having a central male luer cannula, the connector being mounted in fluid connection with the container, the chamber having a luer receiver mounted in flow communication therewith, the receiver including a housing having an inlet, the housing containing a sealing septum mounted adjacent the inlet, the septum having an upper portion including an outer face and a perforation, the septum including a septum extension projecting axially of the housing, said septum upper portion having a width greater than a width of said septum extension, a proximal end of said housing comprising a substantially continuous ring structure defining a platform, said upper portion of said septum being seated on said platform;

• the method comprising steps of:
• pressing a tip of the male luer cannula against the outer face, the ring structure holding the upper portion of the septum in position adjacent the inlet such that the upper portion is held while the luer tip penetrates into the slit and into the outer face of the septum and into the extension,
• deflecting the extension laterally with the luer cannula such that the extension is elastically expanded within the housing in direct contact with the male luer cannula, the cannula penetrating at least partially through the extension into fluid connection with the chamber, and
• flowing liquid through the luer tip and into the chamber.
