In a biological measurement system (10) for collecting one or more samples of sputum and/or mucus from a patient in the form of an aerosol and for analysing said one or more samples to detect whether or not pathogens are present therein, the one or more samples are in solution within the system (10) and detection of the pathogens is performed using a fluorescently labeled assay. The system (10) is adapted to detect bacterial pathogens using evanescent-wave spectroscopy preferably by using a single-reflective technique. The one or more samples are advantageously provided to the system (10) in aerosol form. However, the system (10) is capable of being adapted for use in analysing samples in liquid form. Methods of analysing said one or more samples in the system (10) are described.

Dans un système de mesure biologique (10) permettant de recueillir un ou des échantillons d'une expectoration ou d'un mucus à partir d'un patient sous la forme d'un aérosol et pour l'analyse dudit ou desdits échantillons en vue de détecter si des agents pathogènes y sont présents, ledit ou lesdits échantillons sont en solution au sein du système (10) et la détection des agents pathogènes s'effectue au moyen d'un dosage biologique à étiquettes à fluorescence. Le système (10) est adapté à la détection d'agents pathogènes d'origine bactérienne au moyen de la spectroscopie à ondes évanescentes préférablement mettant en oeuvre une technique de réflexion simple. Ledit ou lesdits échantillons sont avantageusement fournis au système (10) sous forme d'aérosols. Cependant, le système (10) est capable d'être adapté pour une utilisation dans l'analyse d'échantillons sous forme liquide. L'invention concerne également des procédés d'analyse dudit ou desdits échantillons dans le système (10).
