Abstract

A laboratory system for a laboratory automation system is presented. The laboratory system comprises a sample container carrier. The sample container carrier is configured to carry a laboratory sample container and comprises a removal detector. The removal detector is configured to interact with the laboratory sample container to detect a removal of the carried laboratory sample container from the sample container carrier. Furthermore, the laboratory system is configured to determine based on the detected removal that a before valid logic assignment of the sample container carrier to the carried laboratory sample container is invalid.

First claim

We claim:

1. A laboratory system for a laboratory automation system, wherein the laboratory automation system comprises a number of analytical stations, the laboratory system comprising:
a sample container carrier comprising a memory element, a transmitter and a receiver, wherein the sample container carrier is configured to carry only one laboratory sample container between the number of analytical stations, the sample container carrier having a logic assignment to the carried laboratory sample container;
a removal detector arranged in a bottom of a holding region of the sample container carrier and in contact with a lower end of the laboratory sample container's outside circumference,
wherein the removal detector comprises a switch, wherein when a laboratory sample container is present in the sample container carrier, the switch is depressed by the lower end of the laboratory sample container,
wherein the removal detector detects a removal of the carried laboratory sample container from the sample container carrier when the switch is no longer depressed by the lower end of the laboratory sample container,
wherein the memory element is encoded with information based on
information based on whether the logic assignment of the sample container carrier is valid, and/or
information based on whether the logic assignment of the sample container carrier is invalid,
wherein the laboratory system determines based on a detected removal that a previously valid logic assignment of the sample container carrier to the carried laboratory sample container is now invalid and in response to the detected removal the previously valid logic assignment is deleted from memory,
wherein the receiver receives information based on whether the logic assignment is valid, and stores the information on the memory element, and
a control device configured to control the transmitter:
to transmit information based on whether the logic assignment is valid, and
to not transmit if the previously valid logic assignment was deleted and/or the logic assignment is invalid.

2. The laboratory system according to claim 1 , further comprising:
a receiver station, wherein the receiver station receives information from the sample container carrier based on whether the logic assignment is valid.

3. The laboratory system according to claim 1 , further comprising
a transmitter station, wherein the transmitter station is configured to transmit information whether the logic assignment is valid to the sample container carrier.

4. The laboratory system according to claim 1 , further comprising:
a barcode reader and assignment station, the control device controlling the barcode reader and assignment station to read a barcode of the laboratory sample container and to logically assign the read barcode to the sample container.

5. The laboratory system according to claim 1 , further comprising:
a loading and assignment station, the control device controlling the loading and assignment station to load the laboratory sample container on the sample container carrier and to transmit to the sample container carrier that the logic assignment of the sample container carrier to the loaded laboratory sample container is valid.

6. A laboratory sample distribution system for a laboratory automation system, the laboratory sample distribution system comprising:
the laboratory system according to claim 1 ;
a transport plane, wherein the transport plane is configured to support the sample container carrier; and
a number of drive elements, wherein the number of drive elements is configured to move the sample container carrier on the transport plane, the control device controlling the number of drive elements such that the sample container carrier moves on the transport plane along a corresponding transport path.

7. The laboratory sample distribution system according to claim 6 , wherein the sample container carrier comprises a magnetically active device, wherein the number of drive elements comprises a number of electro-magnetic actuators, wherein the number of electro-magnetic actuators is stationarily arranged below the transport plane and is configured to move the sample container carrier on the transport plane by applying a magnetic drive force to the sample container carrier, and wherein the control device controls the number of electro-magnetic actuators such that the sample container carrier moves on the transport plane along the corresponding transport path.

8. A laboratory automation system, the laboratory automation system comprising:
a number of analytical stations, wherein the number of analytical stations is configured to analyze a sample; and
the laboratory sample distribution system according to claim 6 , wherein the laboratory sample distribution system is configured to move the sample container carrier to the number of analytical stations, wherein the laboratory automation system is configured to prevent analyzing and/or logically assigning an analytical result to the sample contained by the carried laboratory sample container based on the determined invalid logic assignment.
