Abstract: A venous air capture chamber for use in dialysis, includes an upwardly extending fluid inlet terminating in first and second fluid inlet ports (102). The first and second fluid inlet ports (102) are opposedly positioned on the fluid inlet at an angle of about 180°. The venous air capture chamber also includes a fluid outlet (104) at the bottom of the chamber body. The venous air capture chamber provides improved fluid dynamics, reducing both stagnant flow and turbulence. The venous air capture chamber also provides for bidirectional flow of fluid through the chamber.

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).
