Casing for metered dose inhaler |
摘要 |
A pocket-sized apparatus for dispensing a metered amount of aerosolised medication comprises a casing (27) defining a cavity, a discharge opening through which the user receives the medication, a valve (59) for the discharge opening which opens under the force provided by inhalation, an air opening (31) through which air enters the cavity and a medication opening. The casing also defines an open pocket for receiving a pressurised canister and there is a passageway to deliver medication from the canister via the medication opening to the cavity. The apparatus also includes means to indicate to the user when to activate the medication at a predetermined inspiratory flow. The apparatus preferably includes an electronic pressure transducer (22) to measure the back pressure of the breath moving through the casing and a cap (58) comprising openings (60) to limit air flow into the casing. |
