Abstract

The invention relates to devices and methods for the identification of test tubes in a test tube rack using RFID technology.

Claims

1. A laboratory device for processing samples, comprising:

a rack holding element for holding an inserted tube rack designed to accommodate at least one test tube having an RFID chip attached thereon, and

an antenna holding element holding an antenna structure element for wireless coupling with the RFID chip of the test tube, the antenna structure element comprising a carrier with at least two antennas applied thereon,

wherein the carrier is made of thin and flexible material and the antenna structure element is held by the antenna holding element in a bent manner such that at least two antennas are brought in pairs into an angular position with each other, and wherein the antenna holding element is positioned adjacent to the rack holding element such that the RFID chip of the at least one test tube is flanked between the pair of two angled antennas while the inserted tube rack is inserted into the rack holding element, wherein the position of the antenna structure element enables coupling of the antennas with the RFID chip.

2. The laboratory device according to claim 1, wherein the antenna holding element forms part of the test tube rack.

3. The laboratory device according to claim 1, wherein the antenna holding element forms part of a rack holding assembly capable of receiving the test tube rack.

4. The laboratory device according to claim 1, wherein the at least two antennas of the antenna structure element are printed on the carrier.

5. The laboratory device according to claim 1, wherein the at least two antennas of the antenna structure element are deposited on the carrier.

6. The laboratory device according to claim 1, wherein the at least two antennas of the antenna structure element are adhered onto the carrier.

7. The laboratory device according to claim 1, wherein the at least two antennas of the antenna structure element comprise a material selected from the group consisting of copper and aluminum.

8. The laboratory device according to claim 1, wherein the at least two antennas of the antenna structure element are produced by a (photo-)lithography process.

9. The laboratory device according to claim 1, wherein the antenna holding element is an antenna receptacle.

10. The laboratory device according to claim 1, wherein the antenna holding element is saw tooth-shaped.

11. The laboratory device according to claim 1, wherein the angle between the at least two paired antennas is between about 0°

and about 180°

.

12. A rack holding assembly comprising:

a rack holding element for holding an inserted tube rack designed to accommodate at least one test tube having an RFID chip attached thereon, and

an antenna holding element holding an antenna structure element for wireless coupling with the RFID chip of the test tube, the antenna structure element comprising a carrier with at least two antennas applied thereon,

wherein the carrier is made of thin and flexible material and the antenna structure element is held by the antenna holding element in a bent manner such that at least two antennas are brought in pairs into an angular position with each other, and wherein the antenna holding element is positioned adjacent to the rack holding element such that the RFID chip of the at least one test tube is flanked between the pair of two angled antennas while the test inserted rack is inserted into the rack holding element, wherein the position of the antenna structure element enables coupling of the antennas with the RFID chip.

13. A laboratory device for processing samples, comprising:

a rack holding element holding an inserted tube rack designed to accommodate at least one test tube having an RFID chip attached thereon, and

an antenna holding element holding an antenna structure element for wireless coupling with the RFID chip of the test tube, the antenna structure element comprising a carrier with at least two antennas applied thereon, the carrier being made of thin and flexible material and the antenna structure element being held by the antenna holding element in a bent manner such that at least two antennas are brought in pairs into an angular position with each other,

wherein the antenna structure element is positioned adjacent to the rack holding element such that the RFID chip of the at least one test tube is flanked between the pair of two angled antennas while the inserted tube rack is inserted into the rack holding element, wherein the position of the antenna structure element enables coupling of the antennas with the RFID chip.
