Device for supplying blood tubes to a whole blood analyser

Abstract

The inventive device comprises stirring means (5) arranged upstream with respect to at least one analyser (4), first transport means (1) for conveying blood tubes (2) one after another in front of stirring means (5), second transport means (1) for conveying the blood tubes stirred by stirring means (5) one after another to the sampling point (6) of the analyser (4) and means (5) for picking up separately the blood tubes which are not yet stirred, placed said tubes in front of steering means (5) in order to be stirred thereby and to be separately removed from stirring means (5) and placed on transport means (1) for conveying the stirred tubes to the sampling point (6) of the analyser (4), thereby making it possible to use at least one analysed devoid of stirring means.

Description

technical field [0001] [01] The present invention relates to a device for providing blood test tubes for a whole blood analyzer. Background technique [0002] [02] A whole blood analyzer is an analyzer that analyzes a blood test tube including all blood components, which is different from an analyzer that operates on plasma or serum. [0003] [03] Unlike analysis performed on plasma or serum, blood for analysis by a whole blood analyzer must be carefully mixed in a very short time prior to analysis. This agitation phase is a minimum requirement in order to homogenize the blood and thus suspend the cells, which naturally settle when the tube is immobilized, and should be performed according to the recommendations of the standardization committee (comités denormalisation). [0004] [04] This agitation phase is handled differently depending on the type of analyzer used and its degree of automation. In the case of the simplest analyzers, the instrument has no agitation means a...

Problems solved by technology

[0020] [20] However, the use of test tube boxes is still limited, especially when the automatic operation line needs to feed multiple analyzers, because all analyzers making up the automatic operation line should be able to accept a unique size test tube box

[0021] [21] Another limitation is that the tubes are processed in batches, which means that any other supplementary operations that need to be performed on a particular tube—such as the analysis of a confirmatory assay or a different The entire cassette moves towards the analysis unit

This patent, like patent application WO95 / 03548, completely ignores the need for mixing and agitation

[0026] [26] As described in the patent US 5 623 415, it follows from the prior art that the use of an analyzer comprising a single tube track cannot easily remove the sample, but only transport it

[0039] [39] During this process, the transition from single-tube mode to cassette mode, and from cassette mode to single-tube mode at the end of the analysis, loses the single-tube mode line normally assigned to plasma or serum analyzers the entire flexibility of
