Abstract

Abstract A test tube rack having columns and rows for manually performing medical diagnostic assays which require various sequential operations. The top face of the rack has indicia such as color strips and written directions to provide a program of operations which is to be followed in a particular assay. The individual test tubes are manually progressed in columns from row to row as the programmed sequence of operations is carried out. The top face may be replaced by other top plates programmed for other different assays.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 231 words
An apparatus for performing medical diagnostic assays requiring the manual performance of a plurality of various operations in sequential order on a group of test tubes, comprising, in combination, a test tube support structure, said test tube support structure having a unitary top face, said top face comprising a plurality of rows of test tube support stations all of which are fixed with respect to said unitary top face, each row having a plurality of laterally spaced and aligned individual test tube stations, the individual stations of each row being in perpendicular alignment with corresponding stations of each of the other rows, the centers of all of the individual stations of all of the rows defining on said top face a grid or pattern of horizontal and vertical lines passing through the centers of all of said stations to permit individual test tubes to be individually manually moved perpendicularly from row to row stepwisely upon the completion of particular assay operations thereupon, one or more of said stations being omitted from one or more of said rows to provide for skipping of certain operations on certain test tubes being manually advanced stepwisely perpendicularly from row to row in the performance of a particular assay, and indicia along each row descriptive of the particular operation to be performed on test tubes stationed along that row in the performance of a particular assay.
Claim 2
Independent Claim 231 words
An apparatus for performing medical diagnostic assays requiring the manual performance of a plurality of various operations in sequential order on a group of test tubes, comprising, in combination, a test tube support structure, said test tube support structure having a unitary top face, said top face comprising a plurality of rows of test tube support stations all of which are fixed with respect to said unitary top face, each row having a plurality of laterally spaced and aligned individual test tube stations, the individual stations of each row being in perpendicular alignment with corresponding stations of each of the other rows, the centers of all of the individual stations of all of the rows defining on said top face a grid or pattern of horizontal and vertical lines passing through the centers of all of said stations to permit individual test tubes to be individually manually moved perpendicularly from row to row stepwisely upon the completion of particular assay operations thereupon, one or more of said stations being omitted from one or more of said rows to provide for skipping of certain operations on certain test tubes being manually advanced stepwisely perpendicularly from row to row in the performance of a particular assay, and indicia along each row descriptive of the particular operation to be performed on test tubes stationed along that row in the performance of a particular assay.
Claim 3
Dependent Claim 48 words
Medical diagnostic assay apparatus as defined in claim 1, wherein said top face is removably fitted with respect to said test tube support structure to provide for the replacement thereof with other face plates, selectively, having different indicia along each row for the performance of other diagnostic assays.
Claim 4
Dependent Claim 32 words
Medical diagnostic assay apparatus as defined in claim 2, wherein said indicia comprises written matter along each row describing the operation to be performed on test tubes stationed along that particular row.
Claim 5
Dependent Claim 80 words
Medical diagnostic assay apparatus as defined in claim 2, wherein said top face comprises a panel member, said test tube support stations comprising openings in said panel member for the reception of test tubes, one or more of said station openings being omitted from one or more of said rows to provide for skipping of certain operations on certain test tubes being advanced stepwisely from row-to-row in the performance of the particular assay for which the face panel is programmed.
Claim 6
Dependent Claim 33 words
Medical diagnostic assay apparatus as defined in claim 4, wherein the indicia along each row comprises a strip of a particular color, coded to the operation to be performed along that particular row.
Claim 7
Dependent Claim 33 words
Medical diagnostic assay apparatus as defined in claim 1, wherein the indicia along each row comprises a strip of a particular color, coded to the operation to be performed along that particular row.
Claim 8
Dependent Claim 35 words
Medical diagnostic assay apparatus as defined in claim 6, wherein said indicia further comprises written matter impressed along each row and describing the operation to be performed on test tubes stationed along that particular row.
Claim 9
Dependent Claim 62 words
Medical diagnostic assay apparatus as defined in claim 6, wherein said top face comprises a panel member, said test tube support stations comprising openings in said panel member for the reception of test tubes, one or more of said station openings being omitted from one or more of said rows to provide for said skipping of certain operations on certain test tubes.
Claim 10
Dependent Claim 35 words
Medical diagnostic assay apparatus as defined in claim 8, wherein said indicia further comprises written matter impressed along each row and describing the operation to be performed on test tubes stationed along that particular row.
