Abstract

A fluid flow sinker including a body having a generally cylindrical sidewall, a first end, a second end, and an aperture extending between the first and second ends; and a fluid passageway disposed on the first end and extending from the generally cylindrical sidewall to the aperture, wherein the fluid flow sinker is adapted to receive a tube in communication with the aperture.

First claim

What is claimed is:

1. A fluid flow sinker comprising:
a body having a first end of the body and an at least partially outwardly rounded second end of the body, wherein the entirety of the body from the first end to the second end has a cylindrical sidewall, and an aperture extending between the first and second ends of the body; and
a fluid passageway disposed on the first end and extending from the cylindrical sidewall to the aperture,
wherein the fluid flow sinker is adapted to receive a tube in communication with the aperture.

2. The fluid flow sinker according to claim 1 , wherein the aperture has a length, L A , wherein a first portion of the aperture has a diameter, D A1 , wherein a second portion of the aperture has a diameter D A2 , and wherein D A2 is greater than D A1 .

3. The fluid flow sinker according to claim 2 , wherein the first portion of the aperture is adjacent the first end of the body, and wherein the second portion of the aperture is adjacent the second end of the body.

4. The fluid flow sinker according to claim 1 , wherein the fluid passageway comprises a plurality of recesses extending from the first end into the body, all of the recesses having a same shape as compared to one another.

5. The fluid flow sinker according to claim 4 , wherein, when viewed from the first end, the plurality of recesses are disposed in a starburst pattern.

6. The fluid flow sinker according to claim 1 , wherein the first end comprises a plurality of projections extending therefrom, and wherein the fluid passageway comprises a fluid passage area free of projections, as defined within a total area as measured between the first end, the cylindrical sidewall, and a plane formed at a distal surface of the plurality of projections.

7. The fluid flow sinker according to claim 1 , wherein the fluid flow sinker has a fluid removal rate as measured according to a fluid removal test of no less than 99%.

8. The fluid flow sinker according to claim 1 , wherein the second end of the fluid flow sinker is adapted such that the aperture remains in fluid communication with a fluid disposed in a vessel when a surface of the second end is oriented in a direction coplanar with a portion of a sidewall of the vessel and when a negative pressure is applied within the aperture.

9. The fluid flow sinker according to claim 1 , wherein the fluid flow sinker has a maximum diameter, D MAX , and a maximum length, L MAX , and wherein L MAX /D MAX is no less than 3.0.

10. The fluid flow sinker according to claim 1 , wherein the fluid flow sinker comprises an average density, as measured at 39° F., of no less than 1.05 g/cm 3 .

11. A fluid flow sinker comprising:
a body including:
a first end of the body and a second end of the body, wherein the entirety of the body from the first end to the second end has a cylindrical sidewall;
an aperture extending between the first and second ends of the body; and
a fluid passageway disposed on the first end, the fluid passageway in communication with the aperture,
wherein the first end is flat and the second end is outwardly rounded, and wherein the fluid flow sinker is adapted to receive a tube in communication with the aperture at the second end.

12. The fluid flow sinker according to claim 11 , wherein the fluid passageway comprises a plurality of recesses extending from the first end into the body, and wherein, when viewed from the first end, the plurality of recesses are disposed in a starburst pattern.

13. The fluid flow sinker according to claim 11 , wherein the fluid passageway comprises a plurality of recesses extending from the first end into the body, wherein each of the plurality of recesses is disposed at a relative angle, A, with respect to an adjacent recess, and wherein A is equal between each adjacent recess.

14. The fluid flow sinker according to claim 11 , the aperture has an average diameter, D A , and wherein D A is constant along a length of the aperture.

15. The fluid flow sinker according to claim 11 , wherein the first end comprises a plurality of projections extending therefrom, and wherein the fluid passageway comprises a fluid passage area free of projections, as defined within a total area as measured between the first end, the cylindrical sidewall, and a plane formed at a distal surface of the plurality of projections.

16. The fluid flow sinker according to claim 11 , wherein the fluid flow sinker has a fluid removal rate as measured according to a fluid removal test of no less than 99%.

17. A fluid flow sinker assembly comprising:
a fluid flow sinker including:
a body having a first end of the body and an at least partially outwardly rounded second end of the body, wherein the entirety of the body from the first end to the second end has a cylindrical sidewall, and an aperture extending between the first and second ends of the body; and
a fluid passageway disposed on the first end, the fluid passageway in communication with the aperture; and
a tube in communication with the aperture at the second end.

18. The fluid flow sinker assembly according to claim 17 , wherein the aperture has an average diameter, D A , and a maximum diameter, D MAX , and wherein D MAX /D A is at least 1.1.

19. The fluid flow sinker assembly according to claim 18 , wherein the fluid passageway comprises a plurality of recesses extending from the first end into the body, and wherein at least one of the recesses has a rectangular profile.

20. The fluid flow sinker assembly according to claim 17 , wherein the fluid flow sinker has a fluid removal rate as measured according to a fluid removal test of no less than 99%.
