Abstract
Abstract Cells are automatically classified and analyzed by staining a measured amount of a specimen with a material which is adapted to fluoresce when illuminated; preparing a slide containing the stained specimen; illuminating the slide with light of successively changing wavelengths to measure the presence of the fluorescent response at each of the predetermined wavelengths to determine the constituents of the specimen. The detected constituents are automatically focused and scanned by a microscope having a capability of locating the constituent of interest, determining its size, shape and texture to thereby provide information as to the type, count and the like to enable a detailed analysis of the specimen.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
161 words
Apparatus for facilitating the analysis of a sample of cellular material, said sample comprising a precipitation of cells stained with material so as to fluoresce when illuminated by light of predetermined wavelengths wherein the wavelength of the light emitted by the stains is determined by the type of cellular material to which the stain adheres, comprising: a microscope slide member (whose) having a unitary examining surface (includes) including at least a first area portion having a light reflective coating and at least a second area portion having a non-reflective surface said first and second area portions being substantially coplanar and adjacent each other so that, a sample of said cellular material is deposited upon adjacent reflective and non-reflective portions of said examining surface, whereby the reflective area of the slide facilitates examination of individual cells through an absorption technique, and the nonreflective area of the slide facilitates examination of individual cells through the examination of the fluorescent response of cellular materials.
Claim 2
Dependent Claim
161 words
Apparatus for facilitating the analysis of a sample of cellular material, said sample comprising a precipitation of cells stained with material so as to fluoresce when illuminated by light of predetermined wavelengths wherein the wavelength of the light emitted by the stains is determined by the type of cellular material to which the stain adheres, comprising: a microscope slide member (whose) having a unitary examining surface (includes) including at least a first area portion having a light reflective coating and at least a second area portion having a non-reflective surface said first and second area portions being substantially coplanar and adjacent each other so that, a sample of said cellular material is deposited upon adjacent reflective and non-reflective portions of said examining surface, whereby the reflective area of the slide facilitates examination of individual cells through an absorption technique, and the nonreflective area of the slide facilitates examination of individual cells through the examination of the fluorescent response of cellular materials.
Claim 3
Dependent Claim
16 words
The slide of claim 1 wherein the stain material includes at least one fluorescent acridine dye.
Claim 4
Dependent Claim
19 words
The slide of claim 1 wherein said stain material is taken from the group comprising corophosphine and acridine orange.
Claim 5
Dependent Claim
83 words
The slide of claim 3 wherein: said stained specimen is spun upon the slide to distribute the cells uniformly in a manner proportional to the total number of said cells in said specimen whereby a first portion of the said specimen is deposited upon the reflective surface and a second portion of the specimen is deposited upon the slide adjacent to the reflective surface; and wherein said slide is scanned with imaged light to sequentially measure absorbed and fluorescing light from the sample.
Claim 6
Dependent Claim
24 words
The apparatus in accordance with claim 1 wherein said microscope slide includes a third area portion having a frosted surface to permit writing thereon.
Claim 7
Dependent Claim
14 words
The apparatus in accordance with claim 1 wherein said second area portion is transparent.
Claim 8
Dependent Claim
17 words
The apparatus in accordance with claim 1 wherein said first area portion is coated with evaporated aluminum.
Claim 9
Dependent Claim
19 words
The apparatus in accordance with claim 1 wherein said first area portion is coated with a reflective mylar tape.
Claim 10
Dependent Claim
15 words
The apparatus in accordance with claim 1 wherein said microscope slide member is acrylic plastic.
Claim 11
Dependent Claim
32 words
The apparatus in accordance with claim 1 wherein said microscope slide member is substantially rectuangular is shape having one corner cut off to permit insertion into a microscope in a prescribed manner.
