Injection site with outer flange
First Claim
1. An injection site used for passing a needle into an enclosed space surrounded by a wall, which comprises:
- an aperture in said wall communicating between said enclosed space and the exterior;
an elastic, needle pierceable member occluding said aperture and exposed to the exterior to define a route of needle access through said member and aperture to the enclosed space;
a first flange positioned adjacent to said member and extending transversely outwardly from said route of needle access, said first flange carrying a second flange extending longitudinally relative to said route of needle access and spaced transversely outwardly from said member to define a catch area for needles surrounding said plug, in which said aperture is defined by a tube-defining body, said body having a pair of tube fittings communicating with said enclosed space and extending in opposed directions substantially perpendicular to said route of needle access for receiving a pair of flexible tubes in sealed connection with said body and aperture.

Abstract
An injection site for passing a needle into an enclosed space surrounded by a wall, typically defined by a tubular section incorporated in a tubular set. An aperture in the wall communicates between the enclosed space and the exterior, having an elastic, needle-pierceable member such as a plug occluding the aperture. The plug is exposed to the exterior on one side and defines a route of needle access through the plug and aperture to the enclosed space. A first flange is positioned adjacent to the plug and extends transversely outwardly from the plug. The first flange carries a second flange, which extends longitudinally relative to the plug, and is spaced transversely outwardly from the plug to define a catch area for needles, which catch area surrounds the plug.

6. An injection site used for passing a needle into an enclosed space surrounded by a wall, which comprises:
an aperture in said wall communicating between said enclosed space in the exterior;
an elastic, needle pierceable member occluding said aperture and exposed to the exterior to define a route of needle access through said pierceable member and aperture to the enclosed space;
a first flange positioned adjacent to said pierceable member and extending transversely outwardly from said route of needle access, said first flange carrying a second flange extending longitudinally relative to said route of needle access and spaced transversely outwardly from said pierceable member to define a catch area for needles surrounding said pierceable member, said aperture being defined by a hollow body, said body having a fitting for receiving plastic blood or medical solution tubing in a position abutting to said aperture, whereby said tubing within the fitting defines said enclosed space.- View Dependent Claims (7, 8, 9)

10. A tubular set which comprises a pair of lengths of flexible tubing, said lengths of tubing being connected in fluid flow relationship to an injection site for passing a needle into an enclosed space of the injection site, said enclosed space communicating with the lumens of said flexible lengths of tubing, said injection site defining a housing and comprising:
an aperture in said housing communicating between the lengths of flexible tubing and the exterior;
an elastic, needle pierceable member occluding said aperture and exposed to the exterior to define a route of needle access through said pierceable member and aperture to the enclosed space;
a first flange positioned adjacent to said needle-pierceable member and extending transversely outwardly from said route of needle access, said first flange carrying a second flange extending longitudinally relative to said route of needle access and spaced transversely outwardly from said needle-pierceable member, to define a catch area for needles surrounding said plug, said housing having a pair of fittings communicating respectively with said lengths of flexible tubing, said fittings extending in opposed directions substantially perpendicular to said route of needle access, said route of needle access being substantially perpendicular to a path of flow through said lengths of flexible tubing and said housing.- View Dependent Claims (11, 12)
