Appeal No. 2000-0188
Application No. 08/900,720
BACKGROUND
Appellants’ invention relates to a device for identifying liquid anaesthetics using the
refractive index and temperature of liquid anaesthetic to determine the identity. An
understanding of the invention can be derived from a reading of exemplary claim 1, which
is reproduced below.
1. A device for use with an anaesthetic administration apparatus for identifying
at least one liquid anaesthetic in said anaesthetic administration apparatus, said
device comprising:
means for determining at least one parameter related to a refractive index
of a liquid anaesthetic to be identified;
means for determining a temperature of said liquid anaesthetic to be
identified; and
analysis means for identifying said liquid anaesthetic to be identified from
said at least one parameter at said temperature.
The prior art references of record relied upon by the examiner in rejecting the
appealed claims are:
