Self-contained reagent package device for an assay

Claim 2

A self-contained reagent package device useful in the performance of chemical and biological assays comprising: a substantially planar support member; a plurality of wells in said support member, all of said wells having open top ends for access thereto, and all but one of said wells being integrally formed as a unitary structure with and from the same material as said support member, said one well having its interior surfaces coated with an immunoreactive substance for carrying out the assay; at least one of said integrally formed wells having a predetermined amount of reagent therein; another of said integrally formed wells being empty so that the specimen to be assayed may be deposited therein; and a protective cover sealed over the open ends of said wells to maintain the incorporated reagents in stable form prior to use thereby providing a self-contained reagent package device.

Claim 3

The device of claim 1 wherein the open top ends of said wells lie substantially in the same plane.

Claim 4

The device of claim 2 wherein said support member is a substantially planar strip having the open top ends of said wells coextensive therewith.

Claim 5

The device of claim 3 wherein said wells are linearly arranged in single file in said support member.

Claim 6

The device of claim 4 wherein said coated well is positioned at one end of said support member and said empty well for the specimen is positioned at the other end of the support member.

Claim 7

The device of claim 1 wherein the protective cover is positioned on the open top ends of the wells such that the empty specimen well is uncovered.

Claim 8

The device of claim 1 wherein said support member and all of said wells are made of plastic.

Claim 9

The device of claim 7 wherein said coated well is made from a plastic different from the plastic of said integrally formed wells.

Claim 10

The device of claim 8 wherein said coated well is made from polystyrene and said integrally formed wells and said support member are made from polypropylene.

Claim 11

The device of claim 1 wherein said coated well is made from a material which is substantially optically clear.

Claim 12

The device of claim 1 wherein said protective cover includes labeling information thereon relating to the nature of the assay to be performed.

Claim 13

The device of claim 11 wherein said information is in the form of a bar code constructed and arranged so as to be read electronically to determine said information.

Claim 14

The device of claim 1 wherein the immunoreactive substance on the interior surface of the coated well is antibody.

Claim 15

The device of claim 1 wherein the empty well for the specimen has a conically-shaped bottom end.

Claim 16

The device of claim 1 which further includes keying means for assuring that the device is insertable into analyzer means in a predetermined direction.

Claim 17

The device of claim 1 wherein said coated well has a lip around its open end and said support member has a detent formed therein so that said coated well is snap-fit in said support member.

Claim 18

A self-contained reagent package device useful in the performance of chemical and biological assays comprising: a substantially planar strip member; a plurality of wells in said strip member, all but one of said wells being integrally formed as a unitary structure with and from the same material as said member; all of said wells being arranged in single file in said member and having open top ends for access thereto with said open top ends lying in substantially the same plane coextensive with the member, the non-integrally formed well being positioned at one end of said member and made from substantially optically clear material and having its interior surfaces coated with an immunoreactive substance for carrying out the assay; at least one of said integrally formed wells having a predetermined amount of reagent therein; one of said integrally formed wells at the other end of the member being empty so that the specimen to be assayed may be deposited therein, said specimen well having a conically-shaped bottom end; and a protective cover sealed over the open ends of said wells except said empty specimen well to maintain the incorporated reagents in stable form prior to use, said cover including labeling information thereon in the form of a bar code constructed and arranged so as to be read electronically to determine said information.

Claim 19

A self-contained reagent package device useful in the performance of chemical and biological assays comprising: a substantially planar strip member; a plurality of wells in said strip member, all but one of said wells being integrally formed as a unitary structure with and from the same material as said member; all of said wells being arranged in single file in said member and having open top ends for access thereto with said open top ends lying in substantially the same plane coextensive with the member, the non-integrally formed well being positioned at one end of said member and made from substantially optically clear material and having its interior surfaces coated with an immunoreactive substance for carrying out the assay; at least one of said integrally formed wells having a predetermined amount of reagent therein; one of said integrally formed wells at the other end of the member being empty so that the specimen to be assayed may be deposited therein, said specimen well having a conically-shaped bottom end; and a protective cover sealed over the open ends of said wells except said empty specimen well to maintain the incorporated reagents in stable form prior to use, said cover including labeling information thereon in the form of a bar code constructed and arranged so as to be read electronically to determine said information.
