Appeal No. 96-0957
Application 08/138,359
24 and (2) locking chambers 26 located on one end of the grooves.
The stated function of Feeney’s rails is to limit the travel of
the piston relative to the tube (see column 3, lines 1-5) while
the locking chambers, by virtue of the fact that the buttons may
be forced or snapped into and out of these chambers, function to
releasably retain the piston in a position wherein the needle is
located inside of the tube. Moreover, as stated on page 5 of the
brief, a self-evident purpose of Feeney’s rails and buttons is
that:
The engagement of the buttons with the rails
inherently prevents the hub from rotating,
and therefore, the syringe barrel can be
attached to, and detached from, the hub.
On the other hand, Quaas is directed to a blood
collecting device which includes (1) a generally tubular, air-
evacuated blood collection container 35 having an otherwise open
end that is closed with a needle-penetrable closure 36 and (2) a
generally cylindrical receptacle 12 having an open end and a
closed end, with a double ended needle cannula fixed to the
closed end in such a manner that one needle 20 protrudes
therefrom and the other needle 22 (which is covered by a
resilient valve sheath 25) is received within the receptacle 12.
