Abstract
A closure system for a conduit defining a connector at its end is provided having increased convenience of use and reliability of sterile sealing. A tubular closure member is provided which may be positioned about the connector in telescoping relation. The closure member surrounds but is spaced from the forward portion of the connector to provide space for antiseptic to be provided, to flow both inside of the connector member and about preferably at least 0.5 centimeter of the exterior forward portion thereof for improved antibacterial effect on the connector. An end closure such as a screw threaded cap may be provided.
Claims17
A closure system for a conduit carrying a connector at its end said connector defining a forward end segment which closure system comprises a flexible, tubular closure member positioned about said connector in sealing relation thereto, said closure member being proportioned to telescope over said connector and defining a groove adapted for snap-fit relation with a projecting flange on said connector and defining annular sealing means for providing a seal between the flexible, closure member and connector, said closure member being spaced from said forward end segment, said closure member carrying a removable cap for access to the system and adapted for enclosing antiseptic which is in contact with both the interior and exterior of said connector and wherein said closure member and removable cap are in a one-piece, molded elastomeric structure, means for limiting the forward penetration of said connector into said closure member, the inner diameter of the flexible structure telescoped around the connector being proportioned to define a space to permit the penetration of antiseptic about a portion of the exterior forward portion of said connector for improved antibacterial effect on the connector.
A closure system for a conduit defining a connector at its end, said connector defining at least a first exterior annular sealing face, said closure system including:
- a hollow, tubular handle member having screw thread means;
- a tubular closure member, the rear end of said closure member defining screw thread means, proportioned to mate in closing relation with the screw thread means of the handle member, said closure member defining means to sealingly press against said sealing face when in closing relation with the handle member, the closure member surrounding but being spaced from the forward portion of said connector;
- said handle member comprising a pair of hinged halves and proportioned to close about the rear portion of said connector in surrounding relation;
- and
- end closure means to sealingly close the forward end of said tubular closure.
A closure system for a conduit defining a connection at its end, said connector defining at least a first exterior, circumferential annular sealing face, said closure system including:
- a hollow, tubular handle member comprising a pair of hinged halves and closed about the rear portion of said connector in surrounding relation;
- a tubular closure member, the rear end of said closure member mating in closing relation with the handle member, said closure member defining means sealingly pressing against the annular sealing face when in closing relation with the handle member, said closure member surrounding but being spaced from the forward portion of said connector, and end closure means to sealingly close the tubular closure member, there being antiseptic present within said tubular closure in contact with both the bore of said connector and exterior end portions thereof, the bore of said conduit being removably sealed at a position adjacent to but spaced from said connector.
The closure system of claim 24 in which said end closure means comprises a separate cap member proportioned for removable sealing relation with the forward end of the tubular closure.
