Appeal No. 95-2960
Application 08/009,381
tubing segments used in dialysis or transfusion, to permit
sterile fluid flow between them (col. 3, lines 15-20; col. 6,
lines 23-24). The rubber tubing segments are connected by a
conductive metal tube which has male and female portions (col.
5, line 40 - col. 6, line 10). When a dialysis bag is
replaced, the male and female portions of the conductive metal
tube are
sterilized with an alcohol lamp (col. 12, line 34 - col. 13,
line 24). Isono’s method differs from that recited in
appellants’ claim 8 in that the rubber tubing segments are not
compressed to isolate free ends thereof, the heating is not
produced by induction, and there is no teaching that the ends
of the rubber tubing segments are sterilized by the heating.
However, Popovich discloses that using clamps to isolate
a portion of the connection tubing between a patient and a
dialysis bag permits a potential contamination zone to be
formed (col. 4, lines 53-59), and that heating the portion
between the clamps using ultraviolet radiation permits all of
the tubing and tubing connector in the potential contamination
