Abstract
Abstract An apparatus including a first and second cylindrical body member separately and coaxially mounted relative to one another with the first body member including a resilient perimeter eye piece mounted about a forward terminal end thereof to permit viewing interiorly of the first cylindrical body member through a focusing lens. The focusing lens coaxially aligned with a plurality of fixed lenses positioned forwardly of a slide receptacle for a slide member directed therethrough for sampling of various blood samples therewithin. A sample transparency is positionable forwardly of the slide member to permit visual observation of normal and abnormal blood samples for comparison with a sample mounted within the slide member. Illumination means is mounted rearwardly of the slide member.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
213 words
A portable microscope apparatus for permitting visual observation in comparison of a blood sample wherein the apparatus comprises, a first cylindrical body selectively securable to a second cylindrical body wherein the first and second cylindrical bodies are coaxially aligned relative to one another, and the second cylindrical body includes a cup shaped cavity defining an illumination compartment therewithin, and the illumination compartment including illumination means therewithin selectively actuatable to effect selective actuation of the illumination means, and the first cylindrical body member including a forward terminal end coaxially aligned with and spaced from the second cylindrical body and the forward cylindrical end defining a forward opening, and a first body web fixedly and diametrically mounted within the first said cylindrical body adjacent said forward opening, first body web adjustably mounting a focusing lens, and adjusting means for axially mounting and adjusting the focusing lens relative to the first body web, and at least one fixed lens member mounted rearwardly of the focusing lens within the first cylindrical body member and coaxially aligned relative to the focusing lens, the said at least one fixed lens positioned between the focusing lens and the illumination means, and a slide member selectively receivable within the first cylindrical body member between the fixed lens and the illumination means.
Claim 2
Dependent Claim

A portable microscope apparatus for permitting visual observation in comparison of a blood sample wherein the apparatus comprises, a first cylindrical body selectively securable to a second cylindrical body wherein the first and second cylindrical bodies are coaxially aligned relative to one another, and the second cylindrical body includes a cup shaped cavity defining an illumination compartment therewithin, and the illumination compartment including illumination means therewithin selectively actuatable to effect selective actuation of the illumination means, and the first cylindrical body member including a forward terminal end coaxially aligned with and spaced from the second cylindrical body and the forward cylindrical end defining a forward opening, and a first body web fixedly and diametrically mounted within the first said cylindrical body adjacent said forward opening, first body web adjustably mounting a focusing lens, and adjusting means for axially mounting and adjusting the focusing lens relative to the first body web, and at least one fixed lens member mounted rearwardly of the focusing lens within the first cylindrical body member and coaxially aligned relative to the focusing lens, the said at least one fixed lens positioned between the focusing lens and the illumination means, and a slide member selectively receivable within the first cylindrical body member between the fixed lens and the illumination means.
Claim 3
Dependent Claim
27 words
Apparatus as set forth in claim 1 including a slide member slot diametrically directed through the first cylindrical body member to selectively receive the slide member therewithin.
Claim 4
Dependent Claim
43 words
Apparatus as set forth in claim 2 including a slide receptacle slot diametrically aligned with the first cylindrical body member positioned between the fixed lens and the slide member, and a translucent comparison slide selectively mounted and received within the slide receptacle slot.
Claim 5
Dependent Claim
49 words
Apparatus as set forth in claim 3 wherein the translucent comparison slide includes a plurality of blood samples positioned within the translucent comparison slide adjacent a perimeter of the translucent comparison slide visually offset from the slide member wherein the slide member is mounted within the slide member slot.
Claim 6
Dependent Claim
45 words
Apparatus as set forth in claim 3 wherein the focusing lens is fixedly mounted to a threaded cylindrical lens body, the threaded cylindrical lens body threadedly mounted through the first body web to permit coaxial adjustment of the focusing lens relative to the fixed lens.
Claim 7
Dependent Claim
37 words
Apparatus as set forth in claim 5 including a further fixed lens coaxially aligned relative to the fixed lens and mounted within the first cylindrical body member between the slide receptacle slot and the first body web.
Claim 8
Dependent Claim
27 words
Apparatus as set forth in claim 6 wherein the forward terminal end of the first cylindrical body member includes a resilient perimeter eye piece coextensively mounted thereto.
Claim 9
Dependent Claim
98 words
Apparatus as set forth in claim 7 wherein the slide member includes a first and second transparent slide, the first and second transparent slide each including a rear terminal end, and the rear terminal end of the first and second slide pivotally mounted together including a hinge strap secured to the rear terminal end of the first and second slide, and a T-shaped slide member handle, and the first and second slide including a forward terminal end, the forward terminal end of the first and second slide complementarily received within a handle cavity formed within the T-shaped handle.
