An inhalation device for delivering doses of medicament to a user comprising: &#x2014;a canister (), said canister being adapted to accommodate the medicament to be dispensed to a user, and &#x2014;a counter () which is connected to the canister (). According to the invention &#x2014;the canister () is adapted to receive the counter () on a base end (), &#x2014;the counter and/or the canister further having contact parts () for their attachment having means for increasing the friction and thereby allowing the counter to fixedly be attached onto the canister in a range of different positions in the lengthwise direction, &#x2014;the counter further being adapted to during the process to assemble the counter to the canister, be urged onto the canister until the length of the counter and canister together is within a predefined tolerance of a predefined length.

Inhalation device and a method for assembling said inhalation device

Actuator for an inhaler for delivering medicament by inhalation. The actuator comprises a main body comprising a tubular member for receiving a canister containing medicament and having a valve stem extending therefrom, and an outlet assembly, as a part formed separately of the main body, comprising a mouthpiece for guiding medicament to the mouth of a user and a nozzle block for receiving the valve stem of the canister and delivering medicament from the canister into the mouthpiece. At least a part of the outlet assembly is configured so as to deform and optionally break on withdrawal of the outlet assembly from the main body so as to prevent re-use of the outlet assembly.

Inhalation device

Inhaler device () comprising an actuator body () and an inhaler canister assembly (), the inhaler canister assembly () is comprised of a canister () with a metering valve at a valve end and a dose counter unit () attached to a base end thereof. Further, the inhaler canister assembly () comprises first position ensuring means (), the actuator body comprises second position ensuring means (), wherein the first and second position ensuring means being complementary mating means, and the first and second position ensuring means being so arranged that the inhaler device () cannot be fired, nor the counter unit () count unless the first and second position ensuring means are in a mating relationship. There is also provided an inhaler canister assembly () and an actuator body ().

Inhaler device that reduces the risk for miscounting a dosage

Actuator for an inhaler for delivering medicament by inhalation, having a mouthpiece for guiding medicament to the mouth of a user; and a removable protection cap for the mouthpiece. The cap is secured to the mouthpiece by a cap retaining member that engages a mating recess in the mouthpiece outer periphery. The cap includes at least one release button arranged to provide an elastic deformation of the cap inner periphery that disengages the cap retaining member from the recess.

Actuator for an inhaler for delivering medicament by inhalation, having a main body with a tubular member for receiving a canister containing medicament and having a valve stem extending therefrom; and an outlet assembly, as a part formed separately of the main body, including a mouthpiece for guiding medicament to the mouth of a user and a nozzle block for receiving the valve stem of the canister and delivering medicament from the canister into the mouthpiece. The actuator belongs to a range of inhaler actuators where the outlet assembly is a common part for the range of actuators, and the members of the range of actuators differ by the physical appearance of the main body. The outlet assembly is formed such that it has all parts of the actuator that come into contact with the medicament during normal use, and the main body and the outlet assembly are configured so as to snap-fit together and are provided with complementary snap catch members.
