Abstract

Ένας ενεργοποιούμενος από την αναπνοή εισπνευστήρας ξηρής σκόνης (1), ο οποίος περιλαμβάνει έναν θάλαμο κυκλοφορίας του αέρα (2) σχήματος ουσιαστικά δίσκου για την αποσυσσωμάτωση του εγκλωβισμένου κονιοποιημένου φαρμάκου χρησιμοποιώντας την ενέργεια του εισπνεόμενου ρεύματος αέρα. Ο θάλαμος έχει ένα ουσιαστικά κυκλικό ή πολυγωνικό πλευρικό τοίχωμα (3) που εκτείνεται γύρω από έναν κεντρικό άξονα (4) μεταξύ του επάνω (5) και του κάτω τοιχώματος (6) του θαλάμου ώστε το ύψος (h) του θαλάμου να είναι μικρότερο από τη διάμετρο του (d). Ένα πλήθος διαύλων παροχής αέρα (7) διαταγμένων γύρω από την περιφέρεια του θαλάμου, οι οποίοι δίαυλοι εκτείνονται από κοινές ή ανεξάρτητες εισαγωγές αέρα και οι οποίοι δίαυλοι εισέρχονται στο θάλαμο ουσιαστικά εφαπτομενικά στο πλευρικό του τοίχωμα. Τουλάχιστον ένας από τους διαύλους παροχής εκτείνεται διαμέσου μιας περιοχής παροχής δόσης σκόνης (8) του εισπνευστήρα. Ο θάλαμος περιλαμβάνει περαιτέρω μια εξαγωγή αέρα (9) που εκτείνεται αξονικά από ένα άνοιγμα εκκένωσης (10) στο κέντρο του επάνω ή του κάτω τοιχώματος του θαλάμου και συνδέεται με ένα δίαυλο εκκένωσης (12) ο οποίος εκτείνεται σε ένα επιστόμιο (13). Ο εισπνευστήρας περιλαμβάνει τουλάχιστον έναν περαιτέρω θάλαμο κυκλοφορίας αέρα για την αποσυσσωμάτωση του εγκλωβισμένου κονιοποιημένου φαρμάκου, με τους θαλάμους να συνδέονται με το επιστόμιο παράλληλα.
