Abstract

An improved connector member is provided for providing sealed and preferably sterile connection between a pair of conduits which each terminate in a hollow, transparent housing where some of the wall portion of each housing comprises an opaque wall portion sealed to the remainder of the housing. The opaque wall portions of each housing are positioned in facing contact with each other and are held in sealed, retentive relationship so that exposure to radiant energy causes them to fuse and open an aperture therethrough. In accordance with this invention, improved retention means are provided to permit the respective housings to be moved together in a path which is generally parallel to the opaque walls into sliding retaining relation. Also, the conduit communicating with the housings may be internally sealed, being openable from the exterior.

Dependent claims

In a connector member providing sealed connection, said connector member comprising a pair of hollow, transparent housings, the hollow interiors of each of said housings being sealable from the exterior, some of the wall of each housing comprising an opaque wall portion separating the hollow housing interior from the exterior, each opaque wall portion being sealed to the remainder of its transparent housing, said housings being positioned together with the opaque wall portions in facing contact with each other, and held in sealed, retentive relationship, whereby upon exposure of connected housings to radiant energy, the opaque wall portions in facing contact can fuse together and open an aperture therethrough, the improvement comprising:

retention means carried by said connector member for retaining said housings together, said retention means including:
track-defining gripper arm means positioned adjacent a first end of each housing, and flange means positioned adjacent a second end of each housing, said flange means of each housing being adapted to fit in sliding retaining relation within the track defined by said gripper arm means of the other housing to retain said housings together in said sealed, retentive relation with the opaque wall portions in facing contact, said flange means and the tracks defined by the gripper arm means occupying a plane which is parallel to the plane of said facing, opaque wall portions.

A connector element for providing sealed connection with a second connector element of similar design, said connector element comprising a hollow, transparent housing communicating with a conduit member, the hollow interior of said housing being sealable from the exterior, some of the wall of said housing comprising an opaque wall portion separating the hollow housing interior from the exterior and sealable by connection to said second connector element with said opaque wall portion in facing contact with a corresponding opaque wall portion of the second connector element, and openable through said connector elements upon exposure of said opaque wall portions to radiant energy, thereby forming an edge-sealed aperture through said opaque portions and providing a virtually sterile connection through the joined connectors, and the improvement comprising:

retention means carried by said connector element for retention to the second connector element, said retention means including:
track-defining gripper arm means positioned adjacent a first end of said housing, and flange means positioned adjacent the second end of said housing, said flange means and the tracks defined by the gripper arm means being parallel to the opaque wall portion, the width of each track defined by the gripper arm means being at least as great as the width of said flange means, whereby the flange means may slideably fit into the corresponding gripper arm means of the second connector element, and the gripper arm means may receive corresponding flange means of the second connector element for sealing of the two connector elements into a single connector member with the opaque wall portions in facing contact.

A connector element for providing sealed, sterile connection with a second connector element of similar design, said connector element comprising a hollow, transparent housing, the hollow interior of said housing being sealable from the exterior, a flat section of said housing wall comprising an opaque wall portion separating the hollow housing interior from the exterior and being sealable by connection to said second connector element in facing contact with a corresponding opaque wall portion of the second connector element, and openable through said connector elements upon exposure to of said opaque wall portions to radiant energy, thereby forming an edge-sealed aperture through said opaque portions and providing a virtually sterile connection through said connector, the improvement comprising:

retention means as part of said connector element for retention to the second connector elements, said retention means including track-defining gripper arm means positioned adjacent the first end of the housing, and flange means positioned adjacent the second end of said housing, said flange means and the track defined by the gripper arm means occupying a plane which is parallel to the plane of said opaque wall portion, the width of the track defined by the gripper arm means being at least as great as the width of said flange means, whereby the flange means may slideably fit into the corresponding gripper arm means of the second connector element, and the gripper arm means may slideably receive corresponding flange means of the second connector element, for sealing of the two connector elements into a single connector member with the opaque wall portion in facing contact;
a conduit member communicating with the hollow interior of said housing, the outer end of said conduit member defining a frangible closed end wall, and a projecting member extending outwardly from said closed end wall, and an annular area of weakness in said end wall about said projecting member, whereby manual bending of said projecting member can cause the rupture of said end wall to permit the opening of the outer end of said conduit member.

A connector element for providing sealing sterile connection with a second connector element, said connector element comprising a hollow, transparent, housing the hollow interior of said housing being sealable from the exterior, a flat section of said housing wall comprising an opaque wall portion separating the hollow housing interior from the exterior and being sealable by connection to the said second connector element in facing contact with a corresponding opaque wall portion of the second connector element, and openable through said connector elements upon exposure of said opaque wall portions to radiant energy, thereby forming an edge-sealed aperture through said opaque portions and providing a virtually sterile connection through said connector, the improvement comprising a conduit member communicating with the hollow interior of said housing, the outer end of said conduit member defining a frangible closed end wall, and a projecting member extending outwardly from said closed end wall, whereby manual bending of said projecting member can cause the rupture of said end wall to permit the opening of the outer end of said conduit member.
