Abstract
La presente invenzione è utilizzabile per una vasta gamma di esami diagnostici nel campo della fisiopatologia respiratoria e in generale per tutte le misure di volume, flusso o pressione dell'espirato dell'uomo o di animali. E' costituita da un boccaglio (ingresso del flusso) e due parti speculari, composte ognuna da una doppia camera tubolare coassiale concentrica (dinamica per il passaggio del flusso e statica per la misura) separate da una retina centrale (resistenza al flusso). Su entrambi le parti è posto normale all'asse delle camere esterne un tubo di sezione ridotta per la lettura della pressione statica. Il trovato consente di ottenere una misura del flusso che attraversa la camera interna rilevando sulla camera statica la pressione differenziale riportata ai due tubi di lettura.The present invention can be used for a wide range of diagnostic tests in the field of respiratory pathophysiology and in general for all measures of volume, flow or pressure of the breath of man or animals. It consists of a mouthpiece (flow inlet) and two specular parts, each composed of a double concentric coaxial tubular chamber (dynamic for the passage of the flow and static for the measurement) separated by a central retina (resistance to the flow). On both sides, a tube of reduced section for reading the static pressure is placed normal to the axis of the external chambers. The invention allows to obtain a measurement of the flow that passes through the internal chamber by detecting on the static chamber the differential pressure reported to the two reading tubes.
