Abstract
An inhaler is disclosed. The inhaler has a housing to receive an elongate strip of blisters each containing a dose of medicament and being sequentially movable into alignment with means for breaching a blister to enable a user to inhale said dose contained therein. The device has a spiral wound element within the housing that receives and coils said strip of blisters that have been breached.
Claims12
An inhaler comprising a housing containing a strip of blisters each blister being defined by a blister cavity containing a dose of medicament and a puncturable lid, the inhaler including means to sequentially move each blister into alignment with means for puncturing said puncturable lid of a blister to enable a user to inhale said dose through said puncturable lid and, a spiral wound element in the said housing, the blister cavities, together with their punctured lids, being received in said spiral wound element to coil the strip, wherein the housing includes a common chamber to receive an unused blister strip and a used portion of that strip, wherein a flexible dividing wall separates the chamber into a used and unused blister compartment, the flexible dividing wall comprising a foam strip.
An inhaler comprising a housing to receive a strip of blisters, and an actuator to sequentially move each blister into alignment with means for opening a blister to enable a user to inhale a dose, the housing including a chamber to receive used blisters and, the inhaler further comprising an indexing wheel around which emptied blisters are fed and which rotates in response to movement of said actuator to draw the blister strip through the housing and sequentially align each blister with said means for opening a blister, the indexing wheel being configured such that blister cavities are partially squashed between the indexing wheel and a wall of the housing to compress said blister cavities as they pass around the indexing wheel.
An inhaler comprising a housing containing a strip of blisters each having a blister cavity containing a dose of medicament with a puncturable lid extending over and sealing said dose within the blister cavity, and an actuator to sequentially move each blister into alignment with means for puncturing the lid of an aligned blister to enable a user to inhale said dose, the housing including a first compartment to contain unused blisters cavities with their lids intact and a second compartment, separated from the first compartment by a movable dividing wall, to receive used blister cavities together with their punctured lids, the inhaler further comprising an indexing wheel around which the used blister cavities and their punctured lids are fed and which rotates in response to movement of said actuator to draw the blister strip through the housing and sequentially align each unused blister cavity with said means for puncturing a blister, the indexing wheel being configured such that used blister cavities, together with their punctured lids, are partially squashed between the indexing wheel and a wall of the housing to compress said blister cavities and punctured lids as the strip passes around the indexing wheel.
