Abstract
An arterial air capture chamber (101) is used in dialysis. The arterial air capture chamber (101) includes an upwardly extending fluid inlet (102) terminating in a fluid inlet port (105) positioned at about a 90° turn relative to a fluid flow of a fluid inlet tube (107). The arterial air capture chamber (101) includes a draw tube (104) with an opposedly positioned beveled opening (306) at about 180° relative to the fluid inlet port (105). The arterial air capture chamber (101) provides improved fluid dynamics, reducing both stagnant flow and turbulence. The arterial air capture chamber (101) also provides for bidirectional flow of fluid through the arterial air capture chamber (101).
Claims20
An arterial air capture chamber, comprising:
- a chamber body comprising a top portion, a bottom portion, and a side portion extending between the top portion and the bottom portion,
- wherein the chamber body defines a center axis and an interior volume;
- a fluid inlet tube located in the interior volume of the chamber body,
- wherein the fluid inlet tube is further defined by at least the side portion of the chamber body and at least one wall,
- wherein the at least one wall extends upwards from the bottom portion of the chamber body,
- a fluid inlet port,
- wherein the fluid inlet port is located between the top portion of the chamber body and the bottom portion of the chamber body,
- a fluid outlet tube comprising a draw tube downwardly extending from the top portion of the chamber body towards the bottom portion of the chamber body, the draw tube terminating in a beveled opening, the beveled opening opposedly positioned on the draw tube from the center axis of the chamber body relative to the fluid inlet tube,
- wherein the fluid inlet port is positioned higher than the beveled opening of the fluid outlet tube relative the bottom portion of the chamber body to induce a downward flow of fluid in the chamber body.
