Abstract
Abstract An inhalation device comprising: (i) a breath-actuated inhaler comprising a medicament reservoir mounted within a housing which comprises a mouthpiece and breath-actuation means which prevents dispensing from the reservoir until a patient inhales through the mouthpiece, and, (ii) a protective casing surrounding the breath actuated inhaler, the casing comprising a body portion and a movable cover which may be displaced to allow a patient access to the mouthpiece to use the breath-actuated inhaler while it is within the casing, the breath-actuated inhaler being removable from the protective casing and operable outside the casing.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
186 words
An inhalation device comprising: (i) a breath-actuated inhaler comprising: a medicament reservoir which comprises an aerosol vial containing propellant and medicament and equipped with a dispensing valve; and a housing which comprises a mouthpiece and breath-actuation means which prevents dispensing from the reservoir until a patient inhales through the mouthpiece, wherein the medicament reservoir is mounted within the housing, and (ii) a protective casing surrounding the breath-actuated inhaler, the casing comprising a body portion, a means for applying a cocking force to the breath-actuated inhaler, and a cover that is movable between a closed position and a displaced position that allows a patient access to the mouthpiece to use the breath-actuated inhaler whilst it is within the casing, the breath-actuated inhaler being removable from the protective casing and operable outside the casing, wherein the means for applying the cocking force comprises: an upper portion of the protective casing which is mounted on the remainder of the body portion by a screw thread arrangement, whereby rotation of the upper portion causes movement thereof along the body portion; and a spring means to actually cock the breath-actuated inhaler.

Claim 3
Dependent Claim
28 words
An inhalation device according to claim 1, wherein the breath-actuated inhaler additionally comprises means for providing an indication of the contents dispensed and/or remaining in the aerosol vial.
Claim 4
Dependent Claim
134 words
An inhalation device comprising: (i) a breath-actuated inhaler comprising: a medicament reservoir which comprises an aerosol vial containing propellant and medicament and equipped with a dispensing valve; means to switch the inhaler from the breath-actuated mode to a press-and-breathe mode; and a housing which comprises a mouthpiece and breath-actuation means which prevents dispensing from the reservoir until a patient inhales through the mouthpiece, wherein the medicament reservoir is mounted within the housing; and (ii) a protective casing surrounding the breath-actuated inhaler, the casing comprising a body portion and a cover that is movable between a closed position and a displaced position that allows a patient access to the mouthpiece to use the breath-actuated inhaler whilst it is within the casing, the breath-actuated inhaler being removable from the protective casing and operable outside the casing.
Claim 5
Dependent Claim
134 words
An inhalation device comprising: (i) a breath-actuated inhaler comprising: a medicament reservoir which comprises an aerosol vial containing propellant and medicament and equipped with a dispensing valve; means to switch the inhaler from the breath-actuated mode to a press-and-breathe mode; and a housing which comprises a mouthpiece and breath-actuation means which prevents dispensing from the reservoir until a patient inhales through the mouthpiece, wherein the medicament reservoir is mounted within the housing; and (ii) a protective casing surrounding the breath-actuated inhaler, the casing comprising a body portion and a cover that is movable between a closed position and a displaced position that allows a patient access to the mouthpiece to use the breath-actuated inhaler whilst it is within the casing, the breath-actuated inhaler being removable from the protective casing and operable outside the casing.
