Apparatus for fluid tube
A fluid tube is disclosed herein. The breathing circuit tube has a wall which comprises a hollow geometry. The wall defines a passageway with a central longitudinal axis therethrough. The wall is expandable and contractible to adjust a diameter and a length of the passageway. The wall includes a partition and one or more corrugations that expand and contract to adjust the diameter and length of the passageway. The corrugations extend between terminal end portions of the wall.
1. A fluid tube comprising:
a wall defining a passageway having a cross-sectional width, the wall comprising a plurality of corrugations, wherein the plurality of corrugations are expandable and contractible to adjust the cross-sectional width; and
a partition secured to the wall within the passageway, wherein a first portion of the partition is configured to overlap a second portion of the partition when the plurality of corrugations are in a contracted position.
2. The fluid tube of claim 1 , wherein the passageway is divided into at least two lumen by the partition.
3. The fluid tube of claim 1 , wherein the partition extends between opposing inner surfaces of the wall.
4. The fluid tube of claim 1 , wherein the wall defines a longitudinal axis through the passageway, and wherein the partition extends along the longitudinal axis.
5. The fluid tube of claim 1 , wherein the partition is planar when the plurality of corrugations are in an expanded position.
6. The fluid tube of claim 1 , wherein the plurality of corrugations are spaced in a helical geometry around a longitudinal axis through the passageway.
7. The fluid tube of claim 1 , wherein the plurality of corrugations comprises a plurality of radial corrugations generally parallel with a longitudinal axis through the passageway.
8. The fluid tube of claim 1 , wherein the plurality of corrugations comprises a plurality of axial corrugations generally perpendicular with a longitudinal axis through the passageway.
9. The fluid tube of claim 1 , wherein the wall comprises a non-corrugated region.
10. The fluid tube of claim 1 , wherein the wall comprises a first non-corrugated region and a second non-corrugated region, and the plurality of corrugations is between the first and second non-corrugated regions.
11. The fluid tube of claim 1 , wherein the wall comprises a cylindrical cross-sectional profile.
12. The fluid tube of claim 1 , wherein in the contracted position, the wall defines a first cross-sectional width, and in an expanded position, the wall defines a second cross-sectional width that is greater than the first cross-sectional width.
13. The fluid tube of claim 1 , comprising a longitudinal partition extending between opposing inner surfaces of the wall and dividing the passageway into at least two lumen.
14. A fluid tube, comprising:
a wall having a first end portion, a second end portion, a corrugated portion between the first and second end portions, and a passageway extending through the first and second end portions;
the corrugated portion comprising a plurality of corrugations, wherein the plurality of corrugations are expandable and contractible to adjust any of a cross-sectional width and a longitudinal length of the corrugated portion; and
a partition secured to the wall within the passageway, wherein a first portion of the partition is configured to overlap a second portion of the partition when the plurality of corrugations are in a contracted position.
15. The fluid tube of claim 14 , wherein the wall comprises a cylindrical cross-sectional profile.
16. The fluid tube of claim 14 , wherein in a contracted position, the corrugated portion defines a first cross-sectional width, and in an expanded position, the corrugated portion defines a second cross-sectional width that is greater than the first cross-sectional width.
17. The fluid tube of claim 14 , wherein the passageway is divided into at least two lumen by the partition.
18. The fluid tube of claim 14 , wherein the partition extends between opposing inner surfaces of the wall.
19. The fluid tube of claim 14 , wherein the plurality of corrugations comprises a plurality of radial corrugations generally parallel with a longitudinal axis extending between the first and second end portions.
20. The fluid tube of claim 14 , wherein the plurality of corrugations comprises a plurality of axial corrugations generally perpendicular with a longitudinal axis extending between the first and second end portions.
