Abstract

A sample container of patient sample material includes a sample container barcode containing patient-identifying information. The sample container barcode on the sample container is read, and a tubular reaction vessel is provided to a printer module configured to print a barcode directly onto a surface of the tubular reaction vessel. The printer module prints a barcode on the surface of the reaction vessel by a thermal printing method, and the barcode printed onto the reaction vessel is associated with the sample container barcode.

First claim

The invention claimed is:

1. A method for automatically processing a patient sample within a sample processing station comprising a carousel, said method comprising:
(a) providing, to a first container holder on the carousel, a sample container having a cap and containing a patient sample, the sample container including a sample container barcode on a surface thereof, the sample container barcode containing patient-identifying information;
(b) with a barcode reader, reading the sample container barcode on the sample container held in the first container holder;
(c) vortexing the sample container held in the first container holder to mix the patient sample;
(d) automatically removing the cap from the sample container held in the first container holder with a capping/decapping mechanism;
(e) with a sample pipettor, automatically aspirating at least a portion of the patient sample from the sample container held in the first container holder;
(f) automatically replacing the cap on the sample container held in the first container holder with the capping/decapping mechanism;
(g) providing a tubular reaction vessel having a cap to a printer module disposed within the sample processing station, the printer module being configured to print a barcode directly onto a surface of the tubular reaction vessel;
(h) with the printer module, printing a barcode on the surface of the reaction vessel by a thermal printing method, the barcode printed onto the reaction vessel being associated with the sample container barcode read in step (b); and
(i) automatically moving the reaction vessel from the printer module to a second container holder on the carousel
(j) automatically removing the cap from the reaction vessel held in the second container holder with the capping/decapping mechanism;
(k) with the sample pipettor, automatically dispensing at least a portion of the patient sample aspirated in step (e) into the reaction vessel held in the second container holder; and
(l) automatically replacing the cap on the reaction vessel held in the second container holder with the capping/decapping mechanism.

2. The method of claim 1 , wherein the sample container barcode and the bar code printed on the reaction vessel are identical.

3. The method of claim 1 , further comprising, prior to step (a), placing the sample container in an input rack and placing the input rack into a sample processing instrument.

4. The method of claim 3 , further comprising moving the sample container with a robotic pick and place mechanism from the input rack to the first container holder, wherein the robotic pick and place mechanism and the sample processing station are located within the sample processing instrument.

5. The method of claim 3 , wherein providing the reaction vessel to the printer module comprises placing the reaction vessel in the input rack that is placed into the sample processing instrument.

6. The method of claim 5 , further comprising moving the reaction vessel with a robotic pick and place mechanism from the input rack to the printer module and then, after step (h), moving the reaction vessel with the robotic pick and place mechanism from the printer module to the second container holder.

7. The method of claim 1 , wherein the reaction vessel is provided with a label and the barcode is printed onto the label.

8. The method of claim 1 , wherein the thermal printing method comprises direct thermal printing or thermal transfer printing.

9. The method of claim 1 , wherein the barcode printed on the surface of the reaction vessel includes additional metadata that is not contained in the sample container barcode, wherein the additional metadata includes one or more of time, volume, type, reagents, and errors.

10. The method of claim 1 , further comprising, after step 1 , moving the reaction vessel to an output rack.

11. The method of claim 7 , wherein printing the barcode on the surface of the reaction vessel with the printer module comprises determining an orientation of the reaction vessel with reference to edges of the label on the reaction vessel.

12. The method of claim 7 , wherein the label includes indicia printed thereon and wherein printing the barcode on the surface of the reaction vessel with the printer module comprises determining an orientation of the reaction vessel with reference to the indicia contained on the label.
