摘要:
An aerosol-generating system is provided, including an aerosol-generating device in cooperation with an aerosol-generating article. The article includes a first sealed compartment having a tubular porous element and a delivery enhancing compound sorbed thereon; and a second compartment having a volatile liquid. The device includes an outer housing adapted to receive the article; an elongate piercing member for piercing the first and second compartments. The elongate piercing member includes a piercing portion adjacent a distal end of the elongate piercing member; a shaft portion; and an obstructing portion adjacent a proximal end of the elongate piercing member. The piercing portion has a maximum diameter greater than the diameter of the shaft portion, and the obstructing portion has an outer diameter such that it fits within the tubular porous element of the article when the article is received in the device. A corresponding aerosol-generating device and aerosol-generating article are also provided.
摘要:
The invention relates to a device (1) for inhaling powdery substances (46), in particular of a medical nature, contained in capsules (31), which can be brought into an emptying position by means of a receptacle (A) that can be moved in a flat housing (2), in which position the capsule wall can be pierced by means of movable needles (34) for the purpose of sucking out the capsule content through a mouthpiece channel (5), which extends in axial extension of the capsule chamber (28). According to the invention, in order to further improve a device of the type in question in particular with regard to user-friendly operation and use of the device, the receptacle (A) is designed as a part of the narrow lateral wall (17) of the flat housing (2) that can be pivoted out to a limited extent about an axis (y) and a partial region of the narrow lateral wall plane (E) is designed as a spring-loaded push-button (36) for the needle bearings (35), in such a way that the partial region moves back to the plane (E) of the narrow lateral wall (17) at a maximum.

The invention relates to a device for dispensing a fluid product, that comprises: a body (10), at least one individual tank (21), a mobile holding means (50) receiving at least one tank (21) and movable between a non-dispensing position and a dispensing position, tank opening means (80) for opening a tank upon the actuation of said opening means, loading means (800) for urging said mobile holding means towards said dispensing position, blocking means (100) for blocking said mobile holding means in a non-dispensing position, inhalation triggering means (60), wherein said blocking means (100) includes a blocking member (110) movable between a blocking position and a release position, said blocking member (110) interacting with a protrusion (501) attached to the mobile holding means (50).
摘要:
A method for aerosolizing a powdered medicament comprises coupling a powder inlet end of a feed tube (14) with a penetration in a receptacle (12) containing the powder. Powder is drawn upward through the tube and dispersed in a high pressure gas stream flowing past a portion of the feed tube. Apparatus comprises the feed tube mounted within a base enclosure proximate a holder for one or more receptacles, which may be formed in a continuous web placed in a cartridge (22). A separate piercing mechanism (26) may be provided.
摘要:
In a device to deliver a powdery medicine into a nasal cavity, one-way valve 33 is built in an air flow passage 31 of a capsule housing/holding part 30, the one-way valve 33 is controlled for the opening pressure by a spring 34 and opens by a pressure of air from the pump 50, the one-way valve end 71 does not interfere the setting/detaching operation of the capsule setting/detaching part 40 and the capsule K when the one-way valve 33 is opened and intrudes as far as the inside of the capsule to disperse the medicine in the capsule K when the one-way valve 33 is opened by pressing of the pump 50 upon dosing thereby capable of reliably dosing at a adequate dose also including the medicine falling as far as the one-way valve 33 to the nasal cavity of the user.
