Connector assembly
First Claim
1. A connector assembly comprisinga female luer connector including a housing having a rigid tubular portion projecting therefrom, a hollow needle mounted in said housing concentrically within said tubular portion, a tubular shield mounted over said needle and including a resilient collapsible tubular portion concentric to said needle and a septum at a distal end of said collapsible tubular portion in facing relation to said needle and a ring disposed about said septum to circumferentially compress said septum and prevent circumferential distortion of said septum;
- anda male luer connector including a hollow tube for movement coaxially into said rigid tubular portion of said female luer housing, said hollow tube being sized to abut and move said septum into said rigid tubular portion while collapsing said collapsible tubular portion of said shield to effect piercing of said needle through said septum and entry into said hollow tube.

Abstract
The connector assembly includes a female luer connector having a hollow needle disposed in recessed position within a rigid tubular portion. A rubber shield having a tubular portion and a septum at one end is positioned over the needle to maintain the needle in a sealed condition. A compression ring is disposed about the rubber septum to hold the septum in compression whereby the punctured area can be punctured many times without leaking when subjected to relatively high pressures. The male connector may be of any suitable type for pushing the rubber septum into the female connector for piercing by the needle of the female connector.

8. A connector comprising
a housing having a rigid tubular portion projecting therefrom; -
a hollow needle mounted in said housing concentrically within said tubular portion; a tubular shield mounted over said needle and including a resilient collapsible tubular portion concentric to said needle and secured at one end to said housing and a septum at a distal end of said collapsible tubular portion in facing relation to said needle; and a ring disposed about said septum to circumferentially compress said septum and prevent circumferential distortion of said septum in response to repeated passage of said needle through said septum. - View Dependent Claims (9, 10, 11, 12)

13. A connector assembly comprising
a first connector including a rigid tubular portion, a hollow needle fixedly mounted within said tubular portion, a resilient collapsible tubular portion concentric to said needle to define an annular gap therewith, a septum of a thin thickness at a distal end of said collapsible tubular portion in spaced facing relation to said needle and having a surface projecting from said tubular portion, and a rigid compression ring disposed circumferentially of said septum to circumferentially compress said septum; - and
a second connector including a hollow tube for projecting into said rigid tubular portion of said first connector, said tube having a lumen and being sized to push said septum into said rigid tubular portion to effect piercing of said needle through said septum into said lumen of said hollow tube. - View Dependent Claims (14, 15)

16. In combination,
a first connector including a rigid tubular portion, a hollow needle fixedly mounted within said tubular portion, a resilient collapsible tubular portion concentrically between said needle and said rigid tubular portion, a cap-shaped septum at a distal end of said collapsible tubular portion for movement between an extended position with a face of said septum at a distal end of said rigid tubular portion and a recessed position within said rigid tubular portion, and a plastic ring disposed circumferentially of said septum to circumferentially compress said septum and prevent circumferential distortion of said septum; - and
means for moving said septum from said extended position to said recessed position to effect piercing of said needle through said septum while resiliently collapsing said collapsible tubular portion. - View Dependent Claims (17, 18, 19, 20)
