摘要:
An inhalation device for dry powder comprising a housing defining a chamber (11) for receiving a dose of powdered medicament in communication with a patient port (23) in the form of a mouthpiece or nasal adapter, the inhalation device additionally comprising: deagglomeration/aerosolisation means to deagglomerate and/or assist aerosolisation of said dose of powdered medicament, which means is operable by a patient-independent energy output source (13), detection means (31) to detect patient inspiration through the patient port (23), and, control means (19) to actuate said deagglomeration/aerosolisation means in response to detection of patient inspiration by said detection means.
摘要:
Un dispositif d'inhalation de poudre sèche comprend un boîtier définissant une chambre (11) qui reçoit une dose de médicament en poudre et communique avec un orifice (23) présenté au patient sous forme d'embouchure ou d'adaptateur nasal. Ledit dispositif comprend également des moyens de désagglomération/aérosolisation permettant de désagglomérer et/ou de contribuer à l'aérosolisation de cette dose de médicament en poudre, lesdits moyens étant actionnés par une source d'énergie (13) indépendante du patient, ainsi que des moyens de détection (31) pour détecter l'aspiration à travers l'orifice présenté au patient. Le dispositif comprend également des moyens de commande (19) pour actionner lesdits moyens de désagglomération/aérosolisation en fonction de la détection d'une aspiration par le patient à l'aide des moyens de détection.
(i) an inhaler (13) including a housing which comprises a mouthpiece and actuation means to prevent dispensing from the reservoir until a patient is ready to inhale through the mouthpiece, and, (ii) a protective casing (1) surrounding the inhaler, the casing comprising a body portion (2) and a movable cover (3) which may be displaced to allow a patient access to the mouthpiece to use the inhaler, causing relative movement of the inhaler (13) and a biasing means (15) within the protective casing (1) thereby cocking the inhaler ready for use, characterised in that the cover (3) is pivotally attached to said casing (1) and a cocking link (7) is pivotally mounted at one end (8) to the cover and has a portion (9,10) in pivotal engagement with the inhaler or biasing means, whereby opening of the cover causes movement of the cocking link (7) and inhaler (13) relative to the biasing means (15), such that the pivot points (8,17) of the cocking link (7) and the pivot point of the cover to the casing (5) pass through a straight line position to an overcentre position at which the inhaler device is cocked.
