Problems solved by technology

The transfer technique described in the above patent appears to be an inflexible technical solution and in no way adapted to modern automated lines operating in full blood mode
[0016] [16] Other patents or patent applications such as US 5 623 415, US 4 039 288, US 5 623 415, WO 95 / 03548 and WO 98 / 01760 describe the use of analyzers comprising single-tube tracks, but these single-tube The track appears to be used only for the transport of the test tubes and does not appear to have any pre-analytical means which would, for example, allow the test tubes to be agitated prior to analysis

Embodiment Construction

[0056] [56] Referring first to FIGS. 1-3 , in which corresponding parts bear the same reference numerals, these figures show a first embodiment variant of the device according to the invention. The device includes a pre-analysis module 1 located between a blood test tube storage area 2 to be analyzed and at least one single-tube analyzer 3 . A single-tube transfer line 4 implemented in the form of a track ensures that the test tubes 5 are transported from the storage area 2 to the pre-analysis module 1 or to one or more single-tube analyzers 3 . The term "single-tube" means that the operation involved (transfer, analysis, etc.) is performed on a single tube, not on multiple tubes.

[0057] [57] The pre-analysis module 1 is used to complete a series of operations in advance before a later analysis. The pre-analytical module comprises a test tube 5 venting and identification device 6, a chamber 7 in which quality control test tubes can be stored and supplied, and a stirrer 8 wh...

Abstract

The inventive device comprises a pre-analytical module (1) which is provided with at least one tube stirrer (8) for homogenising blood and preventing clot formation and disposed on a line (4) for single-tube transfer between an area for storing analysable tubes (2), at least one unitary operating whole blood analyser (3) and automatic tube-loading / unloading means (27, 28, 29) arranged between the tube stirrer (8) and the single-tube transfer line (4). The invention is suitable for blood analysers.

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 means for agitati...
