Methods and systems for selection and use of connectors between conduits
Medical devices including vascular access kits and methods of using the kit are disclosed. In some embodiments, a conduit is measured using an outside diameter measurement apparatus to determine if the conduit is compatible with a connector such that there is a continual lumen between the conduit and the connector. In some embodiments, various outside diameter measurement devices and the methods of their use are disclosed. In some embodiments, the methods of connecting a conduit, and in some embodiments a strain relief structure, to a connector are described.
1. A vascular access kit comprising:
a conduit outside diameter measurement apparatus comprising indicia; and
a connector comprising a first securing structure and a second securing structure each pivotably coupled to the connector and together are configured to close over a first end of the connector, the connector configured to couple to a first end of a first artificial conduit with a first outside diameter and a first end of a strain relief by sandwiching the first end of the artificial conduit and the first end of the strain relief between a portion of the connector and the first and second securing structures such that there is a continual lumen through the first artificial conduit and the connector,
wherein the indicia enable an end user to determine if the first artificial conduit and the strain relief are couplable with the connector when the first end of the artificial conduit and the first end of the strain relief are compared to the indicia,
wherein the connector is one of a plurality of different sized connectors,
wherein the conduit outside diameter measurement apparatus comprises a first portion pivotably coupled to a plurality of members that are substantially the same size and each with a different half crescent cut-away which corresponds to one of a plurality of outside diameter measurements, and
wherein each half crescent cut-away is defined along a bottom edge of each plurality of members, the bottom edge of each plurality of members is coextensive with each other when the bottom edges of the plurality of members engage the first portion.
2. The vascular access kit of claim 1 , wherein the indicia correlate to the plurality of different sized connectors.
3. The vascular access kit of claim 1 , wherein the connector is configured to couple to a first end of a second artificial conduit with a second outside diameter, such that there is a continual lumen through the first artificial conduit, the connector, and the second artificial conduit.
4. The vascular access kit of claim 1 , wherein the first artificial conduit is one of a plurality of different sized artificial conduits.
5. The vascular access kit of claim 4 , wherein each one the different half crescent cut-aways is sized to match an outside diameter of a respective artificial conduit of the plurality of different sized artificial conduits.
6. The vascular access kit of claim 4 , wherein each one of the plurality of different sized artificial conduits is configured to pass into a respective half crescent cut-away.
7. The vascular access kit of claim 4 , wherein each one of the plurality of the different sized connectors is configured to couple with a respective artificial conduit of the plurality of the different sized artificial conduits.
