Embodiment Construction

[0032] These figures not only supplement the invention, but in some cases also illustrate its definition.

[0033] Referring now to FIGS. 1 and 2, an optical fluid inspection device D according to an embodiment of the present invention will be described.

[0034] In the following description we assume that the device D is used to examine (or analyze) a fluid in the form of a blood sample in order to carry out a blood count. However, the invention is not limited to this type of fluid or count. In fact, it involves all types of counts, and various types of analysis, especially flow cytometry.

[0035] As shown in FIG. 1 , an inspection device D according to the invention comprises a measuring vessel 1 , preferably of the type known as a “flow sleeve”, such as that described in French patent FR 2653885 .

[0036] Briefly, a vessel 1 of this type comprises an inner wall on which is placed a converging nozzle 2, usually made of sapphire, and defining a calibrated nozzle, typicall...

Abstract

The invention concerns an optical device for examining a fluid (D) comprising a measuring space (4) including a compulsory passage (5) for the fluid to be examined, at least one source (7) delivering a selected light to optical illuminating means (21-25) serving to collect at least part of the light having traversed the compulsory passage (5) and to deliver same to means (20) serving to analyze the collected light so as to deliver signals representing data borne by same. The optical illuminating means (8-12) comprise first light guiding means (8) including one end (9), opposite the source (7), and configured to deliver the light, derived from the source (7), in accordance with a selected geometry so that it illuminates the compulsory passage (5) in a substantially uniform manner and under a substantially constant intensity.

Description

technical field [0001] The present invention relates to the field of fluid analysis, and in particular to devices for analyzing (or examining) fluids using light. Background technique [0002] In certain fields, eg medical analysis (blood counting or flow cytometry), fluid inspection devices based on the interaction between different components of fluid and light are used. [0003] These devices generally consist of: a measurement space with a mandatory passage for the fluid to be examined; a light source providing selected light to a light illumination device which illuminates the mandatory passage with this light; an optical device whose function is to collect at least some of the The light transmitted through the mandatory channel passes it to analysis means for analyzing the collected light in order to pass a signal representative of the data it carries. A device of this type is described in detail in French patent FR 2653885 . [0004] For example, the data carried by...
