Abstract
A female luer connector for intravascular or urological use is provided with a needle having a closed distal end with an opening in the side of the needle. In addition, the needle is sealingly received within a recess of a rubber septum with an interference fit between the distal end of the needle and the septum. A slit may be formed in the septum to facilitate penetration of the needle through the septum when in use. In one embodiment, the septum has an elongated recess so that the needle may be received under compression in one portion for storage purposes and in a second portion when in use.
Claims33
A connector for intravascular and urological use comprising
- a hollow needle having a closed rounded distal end and at least one opening in a side of said distal end for passage of fluid;
- and
- a septum receiving said hollow needle therein in sealed relation, said septum having a transverse wall and a recess slidably receiving said closed end of said hollow needle, said septum and said needle being relatively movable to permit passage of said distal end of said needle through said wall of said septum.
A female connector comprising
- a rigid tubular housing part having an internal shoulder;
- a hollow needle disposed concentrically within said housing part and in fixed relation thereto, said needle having a closed distal end and at least one opening in a side of said distal end for passage of fluid;
- a rubber septum receiving said distal end of said needle in sealed relation;
- a longitudinally collapsible tubular portion extending from said septum within and spaced from said housing part to permit movement of said septum along said needle to allow said needle to pierce said septum to expose said opening in said needle;
- and
- means on said collapsible tubular portion for abutting said internal shoulder of said rigid tubular housing part to prevent stretching of said collapsible tubular portion under an internal pressure therein beyond a point at which said septum is no longer maintained on said needle in sealed relation.
A female connector comprising
- a housing having a hub and a rigid tubular part extending from said hub;
- a hollow needle mounted in said hub for conveying fluid therethrough to opposite sides of said hub, said needle having a closed distal end and at least one opening in a side of said distal end for passage of fluid;
- a rubber septum within said housing and receiving said needle therein in sealed relation, said septum having a wall at one end and a recess slidably receiving said closed end of said needle in an interference fit relation;
- and
- a longitudinally collapsible tubular portion extending from said septum within said tubular part of said housing to permit movement of said septum over said needle to expose said opening in said needle.
