Abstract

A multi-analyzer system where at least two automatic clinical analyzers are linked together by a bi-directional sample rack shuttle, both analyzers initially capable of performing a slightly different menu of assays. The bi-directional incoming and outgoing sample rack transport system of a first one of the two analyzers is automatically converted into a one-way incoming sample rack transport system adapted and the incoming sample tube transport system of a second of the two analyzers is automatically converted into a one-way outgoing transport system adapted to dispose of all sample racks having sample tubes with samples finally tested by either analyzer. In the event that one of the two analyzers experiences an operating failure, the analyzer system may automatically revert to a single analyzer system employing only the operational analyzer.

Claims

1. A computer controlled automated clinical analyzer system having at least two stand-alone automatic clinical analyzers, each analyzer having a bi-directional incoming and outgoing sample transport system, the system further comprising a bi-directional shuttle linking together the analyzers, and control means for controlling the system being controlled such that the bi-directional incoming and outgoing sample transport system of a first analyzer is automatically converted into a one-way incoming sample transport system adapted to receive all samples to be analyzed by said system, and the bi-directional incoming and outgoing of a second analyzer is automatically converted into a one-way outgoing transport system adapted to dispose of all samples analyzed by either analyzer.

2. The automated clinical analyzer system of claim 1 wherein the system is controlled such that if any one of the analyzers experiences an analytical operating failure, the analyzer system automatically reverts to a stand-alone analyzer system in which samples are supplied only to and analyzed only by an fully functional analyzer.

3. The automated clinical analyzer system of claim 1 wherein the system is controlled such that if the bi-directional shuttle experiences an operating failure, the analyzer system automatically reverts to a stand-alone analyzer system in which samples are supplied only to and analyzed only by a stand-alone analyzer.

4. The automated clinical analyzer system of claim 1 wherein the system is further controlled such that if the one-way incoming sample transport system of the first analyzer experiences a functional failure, then the one-way outgoing transport system of the second analyzer is automatically re-converted into a bi-directional incoming and outgoing sample rack transport system.

5. The automated clinical analyzer system of claim 1 wherein the system is further controlled such that if the one-way outgoing sample transport system of the second analyzer experiences a functional failure, then the one-way incoming transport system of the first analyzer is automatically re-converted into a bi-directional incoming and outgoing sample rack transport system.

6. The automated clinical analyzer system of claim 1 wherein the analyzers have different analyzer menu assays, each analyzer further comprising a reagent cartridge transporter adapted to transport reagent, calibrator and control cartridges and wherein the system is controlled such that if any one of the analyzers experiences an analyzing operational failure, the reagent cartridge transporter and the bi-directional shuttle are controlled to replicate the analyzer menu assays of the analyzer experiencing an analyzing operating failure upon a operational analyzer.

7. The automated clinical analyzer system of claim 1 wherein if an unusually large number of patient samples are scheduled for a particular assay in the analyzer menu assay of a first analyzer and said particular assay is not within the analyzer menu assay of a second analyzer, then the reagent cartridge transporter of the first analyzer and the bi-directional shuttle are controlled to add the particular assay in the analyzer menu assay of the first analyzer within the analyzer menu of the second analyzer.
