Abstract
A fluid connector includes first and second clamping arms coupled together for movement between an open condition and a closed, clamping condition for clamping an end of a length of flexible tubing to a fluid fitting. The first and second clamping arms each have a curved interior surface and at least one barb on each curved interior surface. The barbs are configured to engage the exterior surface of the flexible tubing when the first and second clamping arms are in the closed, clamping condition to form a fluid tight connection between the fluid fitting and the flexible tubing. A fluid system and method of fluid connection using the fluid connector are also disclosed.
Claims15
A fluid connector, comprising:
- first and second curved clamping portions coupled together for movement between an open condition and a closed, clamping condition for clamping an end of a length of flexible tubing to a fluid fitting, the first and second clamping portions each having a curved interior surface and at least one barb on each curved interior surface, the barbs configured to engage the exterior surface of the flexible tubing when the first and second clamping arms are in the closed, clamping condition to form a fluid tight connection between the fluid fitting and the flexible tubing.
A fluid system, comprising:
- first and second clamping portions coupled together for movement between an open condition and a closed, clamping condition, the first and second clamping portions each having a curved interior surface and at least one barb on each curved interior surface,
- a length of flexible tubing, and
- a fluid fitting configured to receive an end of the length of flexible tubing,
- wherein the barb of the first and second clamping portions engage the exterior surface of the flexible tubing when the first and second clamping portions are in the closed, clamping condition to form a fluid tight connection between the fluid fitting and the flexible tubing.
A method of forming a fluid tight connection between a length of flexible tubing and a fluid fitting, comprising:
- directing the end of a length of flexible tubing over a fluid fitting to form fluid passage communicating from the flexible tubing through the fluid fitting,
- placing a fluid connector around the end of the length of flexible tubing,
- moving the first and second clamping portions of the fluid connector into a clamping condition onto the exterior surface of the flexible tubing,
- engaging at least one barb on an interior surface of the first and second clamping portions into the exterior surface of the flexible tubing when the fluid connector is in the clamping condition to thereby form a fluid tight connection between the flexible tubing and the fluid fitting.
