Abstract

A sample container carrier for transporting sample containers, for example test tubes and/or vials, in a laboratory automation system is presented. The sample container carrier comprises a body having a hollow center with a central axis. The hollow center accommodates a lower end of a sample container. The sample container carrier also comprises three resiliently deformable and/or displaceable first retaining elements mounted to the body. The first retaining elements, distributed about the central axis, clamp a sample container inserted in the hollow center. The sample container carrier also comprises three resiliently deformable and/or displaceable second retaining elements mounted to the body. The second retaining elements, distributed about the central axis, clamp the sample container inserted in the hollow center underneath the three first retaining elements. The second retaining elements are arranged at least partly inside the hollow center.

First claim

We claim:

1. A sample container carrier for transporting sample containers in a laboratory automation system, the sample container carrier comprising:
a body having a hollow center with a central axis (A), wherein the hollow center is adapted to accommodate a lower end of a sample container, wherein the body comprises at least two parts, an outer sleeve and an inner sleeve received in the outer sleeve;
a retaining structure formed integrally from bent sheet metal material, wherein the retaining structure comprises three first retaining elements mounted to the body, three second retaining elements mounted to the body, and a connecting band having a hexagonal contour with six side surfaces, wherein the three first retaining elements and the three second retaining elements are arranged in an alternating sequence about the central axis (A) at the six side surfaces of the connecting band, wherein the three first retaining elements are resiliently deformable and/or displaceable, wherein the first retaining elements are distributed about the central axis (A) and adapted to clamp a sample container inserted in the hollow center of the body in an area above the hollow center, wherein the three second retaining elements are resiliently deformable and/or displaceable, wherein the second retaining elements are distributed about the central axis (A) and adapted to clamp the sample container inserted in the hollow center of the body underneath the at least three first retaining elements, wherein the second retaining elements are arranged at least partly inside the hollow center of the body, and wherein the retaining structure is mounted between the outer sleeve and the inner sleeve.

2. The sample container carrier according to claim 1 , wherein the body is provided with a number of upwardly projecting support fingers for supporting the first retaining elements in a direction radially outwards about the central axis (A).

3. The sample container carrier according to claim 1 , wherein the first retaining elements and/or the second retaining elements each comprise a hooked portion having a vertex directed toward the central axis (A).

4. The sample container carrier according to claim 1 , wherein the outer sleeve and/or the inner sleeve is provided with a protruding edge forming a stop for the retaining structure.

5. The sample container carrier according to claim 1 , wherein the body further comprises a sliding disc.

6. The sample container carrier according to claim 5 , wherein the outer sleeve and the inner sleeve are mounted to the sliding disc.

7. The sample container carrier according to claim 3 , further comprising,
a number of retaining strips formed from sheet metal material, each retaining strip comprising one of the first retaining elements and one of the second retaining elements.

8. The sample container carrier according to claim 7 , wherein the body is provided with a number of upwardly projecting support fingers.

9. The sample container carrier according to claim 8 , wherein the retaining strips are attached to the support fingers.

10. The sample container carrier according to claim 7 , wherein the body comprises a sleeve surrounding the hollow center and a sliding disc.

11. The sample container carrier according to claim 10 , wherein the sleeve is mounted to the sliding disc.

12. A laboratory sample distribution system having a number of sample container carriers according to claim 1 .

13. A laboratory automation system with a number of pre-analytical, analytical and/or post-analytical stations and with a laboratory sample distribution system according to claim 12 .
