Abstract: An inhaler for delivery of a dry powder medicament is disclosed that includes a breath sensor for sensing the breath of a patient, a reservoir for the dry powder, a meter for metering an amount of dry powder from the reservoir, and electro-mechanical coupling means for actuating said meter, wherein said coupling means is directly or indirectly responsive to said breath sensor.

Abstract: There is provided a medicament dispenser for dispensing medicament comprising a body having a dispensing outlet; within said body, a medicament container for containing medicament; a dose mover reversibly movable from an initial position to a dispensing position in which the medicament is presented at the dispensing outlet; and a dispensing outlet cover, movable relative to the body from a storage position in which the dispensing outlet is covered to an in-use position in which the dispensing outlet is exposed, wherein the movement of the outlet cover from the storage position to the in-use position is coupled to the movement of the a dose mover from the initial position to the dispensing position.

Abstract: There is provided a medicament dispenser comprising a body (4), a medicament carrier (80), an exit channel (70) for passage of the medicament to a patient, and access means for directly or indirectly exposing the exit channel (70) for use by the patient, wherein the access means (70) comprises an access coupling (74). The coupling (74) is reversibly deformable in response to the application of non-mechanical energy thereto. The non-mechanical energy may comprise heat energy, electrical current energy, electrical field energy or magnetic field energy.

Abstract: There is provided a medicament dispenser comprising a body (44), a medicament container and transport means to transport a metered amount of medicament from a rest position to a delivery position wherein the transport means comprises a transport coupling (72). The coupling (72) is reversibly deformable in response to the application of non-mechanical energy thereto. The non-mechanical energy may comprise heat energy, electrical current energy, electrical field energy or magnetic field energy.

Abstract: A metering device suitable for use in a dry powder inhaler comprises a housing defining a reservoir. The reservoir contains a powder. A rotatable auger, having a first and second end, has one or more flutes extending between the ends. The first end of the auger communicates with the reservoir. A dosing member, defining a dosing recess having a desired volume, is positionable adjacent said second end of said auger. Rotation of said auger causes the powder to be transferred through the flutes and into the dosing recess to fill the recess volume with a specific dose of powder.

Abstract: An inhalation device is described for use with a medicament pack in which at least one container for medicament in powder form is defined between two sheets peelably secured to one another. The device comprises means for peeling the sheets apart at an opening station to open the container; and an outlet, communicating with the opened container, through which a user can inhale medicament in powder form from the opened container.

Abstract: A powder inhalation device comprising a housing containing a pharmacologically active compound, a conduit (8) with an outlet extending into the housing through which a user can inhale to create an airflow through the conduit, a dosing unit (6,7) for delivering a dose of the compound to the conduit and baffles (9) arranged within the said conduit to aid disintegration of powder agglomerates entrained in said airflow. The baffles (9) comprise a plurality of staggered plates extending into the conduit from opposite sides of the conduit at an angle of less than 90.degree. to the sides of the conduit and are inclined towards the outlet to create a plurality of constrictions within the conduit and a plurality of changes in the direction of the said airflow through the conduit.
