Claims
- 1. A reagent cartridge for use with a clinical instrument, the clinical instrument including a wheel which moves the reagent cartridge, the wheel including means for restraining the cartridge, the reagent cartridge comprising:
- a cartridge body which is formed as a single piece structure, the cartridge body comprising: (i) a pair of spaced apart storage wells, each storage well having side walls, a closed bottom, and an upper access opening; and (ii) an integrally formed hollow shell open at the bottom and otherwise substantially encircles the storage wells from below the access opening to provide a hollow space within the shell around the exterior of said wells.
- 2. The reagent cartridge of claim 1 herein the cartridge body is tapered at one end and includes an open space between the lower ends of said wells which receives said means to support and hold the cartridge in a predetermined position.
- 3. The reagent cartridge of claim 1 wherein the reagent cartridge at one end of the body includes an alignment guide and said wheel includes a slot which receives said alignment guide.
- 4. The reagent cartridge of claim 1 where there are two storage wells and an integrally molded handle forms a bridge between the wells.
- 5. The reagent cartridge of claim 1 wherein the sides of the hollow shell includes areas which receive labeling and barcode information.
- 6. A reagent cartridge for use with a clinical instrument, the clinical instrument including means for restraining the cartridge, the reagent cartridge comprising:
- a cartridge body which is formed as a single integral unit, the cartridge body comprising: (i) a pair of storage wells, each storage well having side walls, a closed bottom, and an upper access opening; and (ii) a hollow shell which substantially encircles the wells, the shell providing space around the storage wells for circulating a conditioned fluid within the shell around the storage wells.
- 7. The reagent cartridge of claim 6 wherein the cartridge body includes an alignment guide which engages the means for restraining the cartridge to secure the cartridge body to the clinical instrument.
- 8. The reagent cartridge of claim 7 wherein the cartridge body includes an open space proximate a lower end of each of the wells, the open space being sized and shaped to receive a fin on the clinical instrument to hold the cartridge body in a predetermined position on the clinical instrument.
- 9. The reagent cartridge of claim 8 wherein the cartridge body includes a hole which is sized and shaped to engage a protrusion on the fin of the clinical instrument.
- 10. The reagent cartridge of claim 7 wherein the cartridge body is tapered proximate the alignment guide, wherein the cartridge body includes a handle which forms a bridge between the wells below the access opening, and wherein the shell includes areas which receive labeling and barcode information.
- 11. The reagent cartridge of claim 6 wherein the cartridge body is molded and made of a translucent high density polyethylene.
- 12. The reagent cartridge of claim 6 wherein each storage well includes a threaded portion proximate to the access opening, each threaded portion is sized and shaped to receive a threaded cap to enclose each access opening.
- 13. The reagent cartridge of claim 6 wherein the shell includes an open bottom end.
- 14. A reagent cartridge for use with a clinical instrument, the clinical instrument including a wheel which moves the reagent cartridge, the wheel including means for restraining the cartridge, the reagent cartridge comprising:
- a cartridge body comprising: (i) a pair of storage wells, each storage well having side walls, a closed bottom, and an upper access opening; (ii) an alignment guide which engage the means for restraining to secure the cartridge body to the wheel; and (iii) a hollow shell which substantially encircles the storage well from a point below the access opening, the shell providing space around the storage well for circulating a conditioned fluid within the shell around the storage well.
- 15. The reagent cartridge of claim 14 wherein the shell includes an open bottom end.
- 16. The reagent cartridge of claim 14 wherein the shell includes a thinned out area to permit observation of the fluid levels in the wells.
- 17. The reagent cartridge of claim 14 wherein the cartridge body is molded and formed as a single integral unit.
- 18. A reagent cartridge for use with a clinical instrument, the clinical instrument including a wheel which moves the reagent cartridge, the wheel including means for restraining the cartridge, the reagent cartridge comprising:
- a cartridge body which is formed as a molded, single piece, integral unit, the cartridge body comprising: (i) a pair of spaced apart storage wells, each storage well having side walls, a closed bottom, and an upper access opening; and (ii) an integrally formed hollow shell open at the bottom and otherwise substantially encircles the storage wells from below the access opening to provide a hollow space within the shell around the exterior of said wells, the shell providing space around the storage wells for circulating a conditioned fluid within the shell around the storage wells.
