Insert for Restraining Tube Rotation in a Sample Tube Rack
A sample tube carrier insert having a bottom portions with opposing projections vertically extending above bottom portion so that an interference-fit is formed between the bottom of a sample tube carried by the carrier and the projections to prevent undesirable rotation of the tube.
1 . A clinical sample analysis system comprising:
a sample analyzing module capable of analyzing a clinical sample;
a clinical workstation capable of transporting sample racks carrying sample tubes therein along a pathway proximate said sample analyzing module;
a sample transfer mechanism capable of transferring said sample container from said conveyor to said analyzing module; and,
an insert in said sample tube racks, said insert adapted to prevent rotation of the sample tube carried therein.
2 . The clinical sample analysis system of claim 1 wherein said insert comprises a bottom portion with projections extending vertically upwards.
3 . The clinical sample analysis system of claim 2 wherein said vertically extending projections form an interference fit with said tube.
4 . The clinical sample analysis system of claim 2 wherein said vertically extending projections have a rib-like pattern on the innermost surface thereof.
5 . The clinical sample analysis system of claim 2 wherein said vertically extending projections have an uppermost chamfer adapted to guide said tube between said projections.
6 . The clinical sample analysis system of claim 5 wherein chamfer has a rib-like pattern on the uppermost surface thereof.
7 . An insert for use in a sample tube rack, said insert adapted to prevent rotation of the sample tube carried therein, said insert comprising a bottom portion with projections extending vertically upwards and forming an interference fit with said tube.
8 . The insert of claim 7 wherein said vertically extending projections have a rib-like pattern on the innermost surface thereof.
9 . The insert of claim 7 wherein said vertically extending projections have an uppermost chamfer adapted to guide said tube between said projections.
10 . The insert of claim 9 wherein chamfer has a rib-like pattern on the uppermost surface thereof.
