Abstract
(EN)
A nebuliser comprises means for determining the duration of a pulse of atomisation during inspiration, the determination means including means for measuring the tidal volume (76) of a patient, timing means (77) for measuring the duration of inspiration, means for storing (77) estimates of the volume of a patient's upper airway, and means for calculating (77) the duration of the pulse. The duration of the pulse is calculated on the basis of the tidal volume measuring means (76), the duration of inspiration measured by the timing means, and the stored estimated volume of patient's upper airway from the storage means.

La présente invention concerne un nébuliseur comprenant des moyens de détermination de la durée d'une pulsation de pulvérisation lors d'une inspiration, ces moyens de détermination comprenant des moyens de mesure du volume de respiration (76) d'un patient, des moyens de minutage (77) destinés à mesurer la durée d'inspiration, des moyens de stockage (77) des estimations du volume des voies respiratoires supérieures du patient, et des moyens de calcul (77) de la durée de la pulsation. La durée de la pulsation est calculée sur la base des moyens de mesure du volume de respiration (76), de la durée d'inspiration mesurée à l'aide des moyens de minutage, et du volume estimé des voies supérieures respiratoires du patient provenant des moyens de stockage.
