An improved luer lock receiving septum having a configuration which provides rapid and tight resealing and yet allows penetration of the septum by the luer tip with a low penetration force. The elongated septum includes an upper portion of enlarged diameter having a target surface, a central slit, and a central, lower septum extension projecting about the slit below the upper portion and into a housing so that following luer insertion there is provided sufficient room for both the laterally displaced extension of the septum, the luer taper, and the housing to be received into a conventional luer lock connector. The septum is further preferably configured to minimize or eliminate the negative pressure deflection normally associated with the withdrawal of the large diameter luer cannula from an enclosed fluid filled lumen or chamber, by substantially isolating the lumen or chamber from the septum material displacement resultant from luer insertion.

[ What is claimed is:] [1.] A luer receiver for receiving a male luer tip, the receiver comprising:a housing defining an inner wall, the housing having a proximal end and a distal end and a bore extending from said proximal end towards distal end, a proximal end of said housing being sized to be received into said luer lock connector,a septum having a longitudinal axis and mounted to said housing so as to be disposed at least partially within said bore adjacent said proximal end, said septum having an upper portion with an upper face, an extension portion projecting downwardly from said upper portion, and a slit extending from adjacent said upper face through said upper portion and at least partially through said extension portion, a force being applied by said housing to said septum adjacent said upper face thereby to seal said slit adjacent said upper face, said extension portion having a width in a direction transverse to said slit that is less than a transverse width of said upper portion, said septum and said slit therein 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; andat least one cavity defined lateral to said septum for receiving said displaced septum portion when said luer tip is advanced into said septum.
