Appeal No. 1997-3073
Application No. 07/953,680
of determining concentrations of constituent components of
whole undiluted blood. A significant finding by the Board was
that “Brown uses haemolysed blood” (Decision, page 11).
DECISION
The present appeal is from the final rejection of claims
1 through 44.
The disclosed invention now relates to a method of
determining the concentrations of a plurality of constituent
components of unaltered whole blood.
Claim 37 is illustrative of the claimed invention, and it
reads as follows:
37. A method of determining the concentrations of a
plurality of k constituent components of unaltered whole
blood, k being an integer, comprising:
generating a plurality of n different substantially
monochromatic radiation wavelengths, where n
is
an integer and n > k, k of said n wavelengths
having been selected to measure radiation
absorption by said k constituent components, and n-
k of said n wavelengths having been selected to
compensate for errors due to n-k scattering
factors in unaltered whole blood;
irradiating a sample of unaltered whole blood with
said n radiation wavelengths;
detecting intensities of said n radiation
wavelengths after passing through said sample of
