Method and apparatus for manufacturing a fluid coupling and a fluid coupling made thereby

摘要

A method and apparatus for manufacturing a fluid coupling employs a rod having a bore at one end into which a plurality of plastic tubes may be inserted. The rod is sized to pass through a lumen of a Luer connector and an elastomeric washer placed within a surface of the Luer connector. The rod and plastic tubes are pulled through the Luer connector and washer. After removal of the rod and back tapping of the tubes flush with the end of the connector, a packing material is introduced into the remote end of the connector to fix the tubes in place. The washer then acts as a dam to prevent a flow of packing material from reaching the distal end of the connector. The apparatus employs tube locator blocks which are sandwiched around the rod for guiding the tubes into place in the end of the rod. A piston and cylinder arrangement is used to pull the rod downwardly through these blocks.
