Abstract: A Breath Actuated Inhaler (10) comprising a canister (14) with a medication dispensed when compressing the canister (14). Compression of the canister (14) is prevented by a mechanism only allowing compression when an air flow is sufficient to ensure dispensing of the medication in the lungs/throat of the person. No latch or blocking mechanism is provided so that any force exerted by the person is, at all times, directed to the canister or preventing mechanism so that when no force is exerted by the user, no force is exerted in the inhaler (10). Prolonged exertion of such force could otherwise cause dimension changes and subsequent uncertainty of the dose size.

Abstract: It is an object of the present invention to provide a mechanical blocking device by means of which the user will only be able to initiate an event by activating a stroke of the button or lever past the activation point of the event. Should the movement of the button or lever be stopped or the direction changed before reaching the activation point, retaining means will hinder further movement in the first direction before the lever or button has been brought back to its starting position.

Abstract: The present invention relates to a device for dispensing a medicament from a pressurised canister comprising a mouthpiece, a seat for engagement with the top of the canister and a housing provided with means for guiding and/or holding the canister.

Abstract: An inhaler for delivering medicament by inhalation, comprising a housing for holding a canister of medicament having a body and a valve stem compressible together to actuate the canister to deliver a dose of medicament from the valve stem, an actuation mechanism for compressing the canister, a cannister re-set mechanism comprising a locking element for locking the canister in a compressed state and a release member resiliently biassed by the actuation mechanism on compression of the canister to release the locking mechanism to allow reset of the canister. By provision of the locking element for locking the canister in a compressed state, it is possible to ensure re-set does not occur immediately. The release member subsequently releases the locking mechanism to allow re-set of the canister after a proper dose has been delivered.

Abstract: A breath actuated inhaler for delivering medicament by inhalation, comprising a housing having a mouthpiece and defining an air flow path extending from the mouthpiece through the housing; the housing holding a replaceable canister of medicament actuatable to deliver a dose of medicament into the air flow path, wherein the housing defines an opening in the air flow path and the opening is closed by a closure element connected to and replaceable with the canister. The closure element acts as a safety feature because it is only closed when the inhaler is used with a canister to which a closure element is connected the closure element carries an indication of the type of medicament in the canister to allow the user to recognise the type of medicament. A plurality of inhalers may be provided in which each given inhaler has an opening with a different shape and has a closure element with a shape which conforms with the opening of the given inhaler but which does not conform with the openings of the other inhalers.

Abstract: An inhaler such as a breath-actuated inhaler for delivering medicament by inhalation, comprising a housing for receiving a canister of medicament actuatable to deliver a dose of medicament, a detector for detecting actuation of a received canister, a timer responsive to the detector to measure the elapsed time from actuation of the canister, and an indicator means responsive to the timer to indicate when a predetermined time has elapsed during which the user should maintain inhalation or delay exhalation. This allows the inhaler to provide an indication of how the user should breath to properly receive a dose of medicament. The indicator means may be further responsive to the timer to indicate when a second predetermined time has elapsed.
