[1] Claims 18-21 set forth a method of performing hemodialysis. The subject matter of claims 18-21 relates to a treatment method of the human or animal body, and therefore, according to the criteria set out in Rule 39.1(iv), relates to subject matter for which an international search is not required.
2.
Claims Nos.:
because they relate to parts of the international application that do not comply with the prescribed requirements to such an extent that no meaningful international search can be carried out, specifically:

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).


6. Drawings
a.
The figure of the drawings to be published with the abstract is Figure No.     1    
as suggested by the applicant.
