Embodiment Construction

[0183] Fig. 1 schematically shows a unique dilution and analysis tank 1, which can provide a blood sample 2 to be analyzed, a diluent 3 and a reagent 4 to form an analysis solution together. This tank 1 is equipped with means 5 for measuring the level of hemoglobin in said analysis solution by photometry, and means 6 for measuring the resistance of said analysis solution in order to calculate the total number of leukocytes. Also provided are some means for withdrawing a portion of the analysis solution from the analysis tank 1 and for injecting it into an optical tank 7 equipped with an optical measuring device 8 (such as a flow cytometer) for analysis leukocyte. According to selected embodiments, there are also provided means for withdrawing a portion of the sample pre-solution consisting of blood and diluent and injecting it into the counting and dilution tank 9 equipped for measuring said portion Solution resistant device 10 for counting red blood cells and platelets. The...

Abstract

The invention concerns a circulation vessel (300) adapted to an optical device (120) for leukocyte counting and / or differentiation in a blood analyzing automaton. The invention is characterized in that in an analyzing zone of the vessel (403), the cross section of the vessel has at least one transverse dimension ranging between 1 and 5 millimeters. It can advantageously be made, at least partly, from an injected plastic material and comprises at least one lens (302) molded in one single piece with the vessel (300).

Description

technical field [0001] The present invention relates to a flow-through cell for an optical device suitable for counting and identifying leukocytes in automated blood analysis equipment. It also relates to an analytical device equipped with such a tank. Background technique [0002] Analysis by blood samples is usually devoted to determining: [0003] - the total number of white blood cells; [0004] - More specifically, the number of white blood cells by sub-population (basophils, eosinophils, neutrophils, monocytes and lymphocytes); [0005] - the number of red blood cells and platelets; and [0006] - Hemoglobin level. [0007] Various analytical techniques are known, in particular: [0008] - Hemoglobin determination is performed after erythrocyte lysis, i.e. destruction of the red blood cell membrane, and is determined by spectrophotometric measurement of hemoglobin released in the culture medium; hemoglobin determination also requires hemoglobin in a complex form (...
