Abstract

Multiple lumen intravenous tubing systems can include multi-lumen tubing that can be coupled with a manifold, where the multi-lumen tubing includes multiple lumens extending within the tubing and which are fluidly coupled with counterpart fluid flow paths of the manifold when the multi-lumen tubing is connected to an outlet of the manifold, and where the manifold includes more than one inlet and an outlet with each inlet fluidly coupled to a respective fluid flow paths that can be fluidically separated from the other fluid flow paths of the manifold to permit directing a first fluid from through the manifold and multi-lumen tubing, and a second fluid through the manifold and multi-lumen tubing, without the first and second fluids intersecting.

First claim

What is claimed is:

1 . A multi-lumen intravenous tubing system comprising:
a multi-lumen tubing comprising a primary lumen and a secondary lumen, the primary lumen and the secondary lumen each extending from a first end of the multi-lumen tubing to a second end of the multi-lumen tubing, and the secondary lumen is fluidly separated from the primary lumen; and a manifold comprising a first fluid flow path, a second fluid flow path, a first inlet, a second inlet, and an outlet, the first fluid flow path extending from the first inlet to the outlet, and the second fluid flow path extending from the second inlet to the outlet, wherein the first fluid flow path is fluidly separated from the second fluid flow path; wherein the first end of the multi-lumen tubing is coupled to the outlet of the manifold with the first fluid flow path fluidly coupled to the primary lumen, and the second fluid flow path fluidly coupled to the secondary lumen.

2 . The multi-lumen intravenous tubing system of claim 1 , wherein the primary lumen forms a primary lumen cross-sectional profile that is transverse to a longitudinal primary axis of the primary lumen, and the secondary lumen forms a secondary lumen cross-sectional profile that is transverse to a longitudinal secondary axis of the secondary lumen, and wherein an area of the primary lumen cross-sectional profile is greater than an area of the secondary lumen cross-sectional profile.

3 . The multi-lumen intravenous tubing system of claim 1 , wherein the primary lumen forms a first volume between the first end and the second end of the multi-lumen tubing, and the secondary lumen forms a second volume between the first end and the second end of the multi-lumen tubing, and wherein the first volume is greater than the second volume.

4 . The multi-lumen intravenous tubing system of claim 1 , wherein the primary lumen defines a longitudinal primary axis, and the secondary lumen defines a longitudinal secondary axis, and wherein the longitudinal primary axis is parallel with the longitudinal secondary axis.

5 . The multi-lumen intravenous tubing system of claim 1 , wherein the secondary lumen comprises a first secondary lumen and a second secondary lumen.

6 . The multi-lumen intravenous tubing system of claim 5 , wherein each of the first secondary lumen and the second secondary lumen are positioned concentrically around the primary lumen.

7 . The multi-lumen intravenous tubing system of claim 6 , wherein each of the first secondary lumen and the second secondary lumen define a longitudinal secondary axis that is parallel to a longitudinal primary axis of the primary lumen.

8 . The multi-lumen intravenous tubing system of claim 1 , wherein the primary lumen forms a primary lumen cross-sectional profile having a circular shape, and the secondary lumen forms a secondary lumen cross-sectional profile having a circular shape.

9 . The multi-lumen intravenous tubing system of claim 1 , wherein a length of the primary lumen, from the first end to the second end of the multi-lumen tubing, is equal to a length of the secondary lumen, from the first end to the second end of the multi-lumen tubing.

10 . The multi-lumen intravenous tubing system of claim 1 , wherein the multi-lumen tubing comprises an outer surface forming a cross-sectional profile of multi-lumen tubing, and wherein the cross-sectional profile of multi-lumen tubing is circular.

11 . The multi-lumen intravenous tubing system of claim 1 , wherein the manifold comprises a tertiary fluid flow path that extends from the first fluid flow path to the second fluid flow path.

12 . The multi-lumen intravenous tubing system of claim 11 , wherein the manifold comprises a valve configured to selectively permit a fluid to move from the first fluid flow path to the second fluid flow path.

13 . A multi-lumen intravenous tubing system comprising:
a medicament source; a fluid connector; a manifold comprising a first fluid flow path that extends from a first inlet to an outlet of the manifold, a second fluid flow path that extends from a second inlet to the outlet, wherein the first inlet is fluidly coupled to the medicament source; and a multi-lumen tubing comprising a first end, a second end, a primary lumen, and a secondary lumen, the first end coupled to the outlet of the manifold, the second end coupled to the fluid connector, and each of the primary lumen and the secondary lumen extending from a first end to the second end of the multi-lumen tubing; wherein a first fluid can move from the medicament source, through the first fluid flow path of the manifold and the primary lumen, to the fluid connector, and wherein a second fluid can move from the second fluid flow path, through the second fluid flow path and the secondary lumen, to the fluid connector.

14 . The multi-lumen intravenous tubing system of claim 13 , wherein the secondary lumen is fluidly separated from the primary lumen.

15 . The multi-lumen intravenous tubing system of claim 13 , wherein the manifold comprises a tertiary fluid flow path that extends from the first fluid flow path to the second fluid flow path.

16 . The multi-lumen intravenous tubing system of claim 15 , wherein the manifold comprises a valve configured to selectively permit at least a portion of the first fluid to move from the first fluid flow path to the second fluid flow path.

17 . The multi-lumen intravenous tubing system of claim 13 , wherein the primary lumen forms a first volume between the first end and the second end of the multi-lumen tubing, and the secondary lumen forms a second volume between the first end and the second end of the multi-lumen tubing, and wherein the first volume is greater than the second volume.

18 . A method for providing a multi-lumen intravenous tubing system, the method comprising:
providing a manifold comprising a first fluid flow path that extends from a first inlet to an outlet of the manifold, a second fluid flow path that extends from a second inlet to the outlet of the manifold; and providing a multi-lumen tubing comprising a first end coupled to the outlet of the manifold such that a primary lumen of the multi-lumen tubing is fluidly coupled with only the first fluid flow path, and a secondary lumen of the multi-lumen tubing is fluidly coupled with only the second fluid flow path.

19 . The method of claim 18 , wherein providing a manifold further comprises providing a tertiary fluid flow path between the first fluid flow path to the second fluid flow path, such that at least a portion of a fluid can move from the first fluid flow path to the second fluid flow path.

20 . The method of claim 19 , further comprising providing a valve along the tertiary fluid flow path to selectively permit or resist movement of the fluid between the first fluid flow path and the second fluid flow path.
