Patent number: 9867925Abstract: In general, multiple embodiments of a catheter/fistula needle to bloodline connection assurance device, which secures and strengthens a connection between an extension tube end of a catheter or fistula needle and a bloodline, are provided. In one embodiment, the assurance device includes a clamshell having two halves that open rotatably about at least one hinge. The assurance device includes a male luer portion that pressure seals to the male luer portion of the bloodline connector. The bloodline male luer portion of the device extends to a female luer portion, which is lined with a compressible material that conforms around any industrial catheter/fistula needle connector when the assurance device is closed about the mated connectors. Once the assurance device is closed, this prevents axial movement of the bloodline connector relative to the assurance device.Type: GrantFiled: December 6, 2013Date of Patent: January 16, 2018Assignees: Baxter International Inc., Baxter Healthcare SAInventors: Bernard J. Lyons, Shincy J. Maliekkal, William Patrick Burns, Justin Belanger Rohde, Serhan Acikgoz, Roshni S. Barot, Yuanpang S. Ding, Brian Connell, William R. Griswold

Publication number: 20140100548Abstract: In general, multiple embodiments of a catheter/fistula needle to bloodline connection assurance device, which secures and strengthens a connection between an extension tube end of a catheter or fistula needle and a bloodline, are provided. A first embodiment of the assurance device is configured for use with a bloodline connector having locking clips which are biased slightly outwardly from the bloodline connector. The first embodiment of the assurance device includes clamshell halves that open rotatably about at least one hinge. The first embodiment of the assurance device includes an upper, threaded portion and a lower housing portion. The interior wall of the upper portion defines a plurality of barbs configured to engage with distal or moveable ends of the locking clips. Each locking clip is biased slightly outwardly to enable the distal or moveable end of the locking clip to fit between two respective barbs.Type: ApplicationFiled: December 6, 2013Publication date: April 10, 2014Applicants: Baxter Healthcare S.A., Baxter International Inc.Inventors: Bernard J. Lyons, Shincy J. Maliekkal, William Patrick Burns, Justin Belanger Rohde, Serhan Acikgoz, Roshni S. Barot, Yuanpang S. Ding, Brian Connell, William R. Griswold

Publication number: 20140094775Abstract: In general, multiple embodiments of a catheter/fistula needle to bloodline connection assurance device, which secures and strengthens a connection between an extension tube end of a catheter or fistula needle and a bloodline, are provided. One embodiment includes internal and external clamshells. Internal clamshell halves pressure seal to the bloodline connector, and form outwardly extending barbs. The external clamshell opens rotatably about at least one hinge and includes inwardly facing threads that catch the outer barbs of the internal clamshell. After a user connects the catheter or fistula needle to the bloodline, the user closes the internal clamshell about the bloodline connector. Then, the user closes the external clamshell about the internal clamshell, causing the inwardly facing barbs of the external clamshell to engage the outwardly facing barbs of the internal clamshell. Such engagement prevents axial movement of the bloodline connector relative to the external clamshell.Type: ApplicationFiled: December 6, 2013Publication date: April 3, 2014Applicants: Baxter International Inc.Inventors: Bernard J. Lyons, Shincy J. Maliekkal, William Patrick Burns, Justin Belanger Rohde, Serhan Acikgoz, Roshni S. Barot, Yuanpang S. Ding, Brian Connell, William R. Griswold

Patent number: 8603022Abstract: In general, multiple embodiments of a catheter/fistula needle to bloodline connection assurance device, which secures and strengthens a connection between an extension tube end of a catheter or fistula needle and a bloodline are provided. A first embodiment of the assurance device is configured to be compatible with any industrial catheter/fistula needle female luer connector and is specifically configured for use with a bloodline connector having locking clips which are biased slightly outwardly from the bloodline connector. The first embodiment of the assurance device is cylindrical and includes clamshell halves that open rotatably about at least one hinge. The first embodiment of the assurance device includes an upper, threaded portion and a lower housing portion. The interior wall of the upper portion defines a plurality of barbs configured to engage with distal or moveable ends of the locking clips.Type: GrantFiled: December 17, 2009Date of Patent: December 10, 2013Assignees: Baxter International Inc., Baxter Healthcare S.A.Inventors: Bernard J. Lyons, Shincy J. Maliekkal, William P. Burns, Justin B. Rohde, Serhan Acikgoz, Roshni S. Barot, Yuanpang S. Ding, Brian Connell, William R. Griswold
