Abstract

A fluid transport system is provided. The fluid transport system may include a vessel closure assembly including one or more conduits, a vessel, and a container. A conduit terminus may be engaged with the conduit and received in the vessel. The conduit terminus may include a body with a head portion and an engagement portion, wherein an aperture extends therethrough. The engagement portion may be configured to engage the conduit. The head portion may taper to a tip defining a first opening to the aperture having a hyperbolic paraboloid shape.

First claim

1 . A conduit terminus, comprising:
a body comprising a head portion and an engagement portion, the body comprising an aperture extending along a longitudinal axis through the head portion and the engagement portion and between a first opening at the head portion and a second opening at the engagement portion, the head portion tapering to a tip defining the first opening, the first opening having a contour that is non-planar, wherein the tip has a hyperbolic paraboloid shape such that the tip forms a recess at the first opening that is concave when viewed from a first direction and the tip forms a protrusion at the first opening that is convex when viewed from a second direction perpendicular to the first direction.

2 . The conduit terminus of claim 1 , wherein the first opening is substantially circular and having a radius, the contour of the first opening having a radius of curvature with respect to an axis extending substantially perpendicular to the longitudinal axis, and
wherein the radius of the first opening is less than the radius of curvature of the contour of the first opening at the tip.

3 . The conduit terminus of claim 1 , wherein the first opening is substantially circular and having a first radius,
wherein the second opening is substantially circular and having a second radius, and wherein the first radius of the first opening is less than the second radius of the second opening.

4 . The conduit terminus of claim 1 , wherein the head portion comprises a plurality of ribs.

5 . The conduit terminus of claim 4 , wherein the head portion further comprises a stop configured to abut an end of the conduit.

6 . The conduit terminus of claim 5 , wherein the ribs extend from the stop to the tip.

7 . The conduit terminus of claim 1 , wherein the body comprises a thermoplastic.

8 . A fluid transport system comprising the conduit terminus of claim 1 and further comprising:
the conduit; and
a vessel.

9 . The fluid transport system of claim 8 , further comprising a container, wherein the conduit terminus, the conduit, and the vessel are sealed in the container.

10 . The fluid transport system of claim 9 , wherein the conduit terminus, the conduit, and the vessel define an aseptic system within the container.

11 . A method of fluid removal, comprising:
providing a conduit, a vessel, and a conduit terminus according to claim 1 ; at least partially filling the vessel with a fluid; and withdrawing at least some of the fluid from the vessel through the conduit terminus and the conduit.

12 . The method of claim 11 , further comprising inserting the conduit terminus and at least a portion of the conduit into the vessel.

13 . The method of claim 12 , wherein inserting the conduit terminus and at least the portion of the conduit into the vessel comprises engaging the tip of the conduit terminus with a wall of the vessel.

14 . The method of claim 13 , wherein engaging the tip of the conduit terminus with the wall of the vessel comprises engaging a bottom wall of the vessel.

15 . The method of claim 11 , further comprising providing a vessel closure defining a conduit aperture.

16 . The method of claim 15 , further comprising inserting the conduit through the conduit aperture.

17 . The method of claim 16 , further comprising engaging the vessel closure with the vessel.

18 . The method of claim 11 , further comprising engaging the engagement portion of the conduit terminus with the conduit.

19 . The method of claim 18 , wherein engaging the engagement portion of the conduit terminus with the conduit comprises inserting the engagement portion into a distal end of the conduit until the distal end abuts a stop associated with the head portion of the conduit terminus.
