Abstract

A storage module for a laboratory automation system, a method of operating a laboratory automation system, and a laboratory automation system are presented. Items used by laboratory stations are stored centrally in a storage module and can be transported to the laboratory stations using a laboratory sample distribution system.

First claim

We claim:

1. A laboratory automation system, the laboratory automation system comprising:
a plurality of laboratory stations;
a laboratory sample distribution system comprising a number of sample container carriers, wherein the sample container carriers are configured to carry one or more sample containers, wherein the sample containers comprise samples to be analyzed by the laboratory stations, a transport plane, wherein the transport plane is configured to support the sample container carriers, a driver, wherein the driver is configured to move the sample container carriers on the transport plane, and
a control device, wherein the control device is configured to control the driver such that the sample container carriers move over the transport plane along predetermined transport paths;
a storage module attached to the laboratory sample distribution system, comprising
a plurality storage areas configured for storing items that are to be transported by the laboratory sample distribution system, wherein the storage areas are configured to dispose the stored items to sample container carriers and/or to transport carriers, wherein the transport carriers are configured to carry one or more items, wherein the driver is configured to move the transport carriers on the transport plane, wherein the control device is configured to control the driver such that the transport carriers move over the transport plane along predetermined transport paths, a processor, wherein the processor is configured to process the stored items and wherein the processor comprises a calibration substance preparation unit configured to prepare a calibration substance,
an internal transfer unit configured for transporting substances required for preparation of the calibration substance calibration substance preparation unit, and

a transfer unit for filling of a sample container with the calibration substance; and
a process control unit, wherein the process control unit is configured to control the laboratory stations, the laboratory sample distribution system, and the storage module and wherein the process control unit is configured to:
detect that items are missing or are running short at one of the laboratory stations,
in response to the detecting, dispose a number of such items from one of a number of storage areas of the storage module, and
transport the items to the laboratory stations using the laboratory sample distribution system, wherein the items are at least one of reagents, tubes, tips, pipetting heads, labels, cartridges comprising a set of reagents used in the laboratory stations and/or other consumables used by the laboratory stations, wherein the items are transported by the sample container carriers of the laboratory sample distribution system.

2. The storage module according to claim 1 , wherein handlers are assigned to the storage areas and wherein the handlers are configured to effect the disposal of the stored items to the sample container carriers or to the transport carriers by loading the items from the storage areas on the sample container carriers or on the transport carriers.

3. The storage module according to claim 1 , wherein the processor is configured to plan and/or cause and/or control the processing of the stored items and/or is configured to cause disposal of the prepared calibration substance to the sample container carriers and/or to the transport carriers.

4. The laboratory automation system according to claim 1 , further comprises,
detecting that at least one storage area is empty or is running short of items stored by the storage areas; and
in response to the detecting, generating a signal indicating that the storage areas should be filled and/or replaced.

5. The laboratory automation system method according to claim 1 , wherein at least some of the items are liquids and are transported using containers of the transport carriers.

6. The laboratory automation system method according to claim 1 , wherein the detecting that a type of items is running short comprises detecting that a number, or amount, of such an item is less than 10% of a maximum capacity.
