Abstract
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.
