Abstract

CET APPAREIL COMPREND UN BOITIER 10 RENFERMANT UNE CHAMBRE QUI CONTIENT UN VOLUME DE GAZ DETERMINE SOUS UNE PRESSION EGALEMENT DETERMINEE, PAR EXEMPLE UNE CARTOUCHE D'ANHYDRIDE CARBONIQUE LIQUIDE 21, UN CONDUIT 13 DE SORTIE DU GAZ QU'ON PEUT METTRE EN COMMUNICATION AVEC LA CHAMBRE, PAR EXEMPLE LA CARTOUCHE 21 AU MOYEN D'UNE PERFORATION 26, CE CONDUIT SE TERMINANT PAR UN ORIFICE CALIBRE 17 PRECEDE D'UN FILTRE 19. LA QUANTITE DE GAZ CONTENU DANS LA CARTOUCHE 21, SA PRESSION ET LE DIAMETRE DE L'ORIFICE 17 SONT CALCULES DE MANIERE QUE L'APPAREIL DEBITE LE GAZ DANS LE SPIROMETRE DANS DES CONDITIONS DE VOLUME ET DE DEBIT (DIMINUANT SUIVANT UNE FONCTION EXPONENTIELLE) A PEU PRES ANALOGUES A CELLES QUE L'ON RENCONTRE DANS L'UTILISATION NORMALE DU SPIROMETRE.
