A recently granted patent (Publication Number: US11865247B2) discloses a breath-actuated inhaler designed to deliver medication efficiently. The inhaler comprises a canister housing with a displaceable canister containing a metering valve stem, metering chamber, and drug reservoir. The canister is moved by a drive mechanism applying variable forces, including a ready-to-fire force in equilibrium with other forces like a dose counter biasing element and a vacuum chamber. The inhaler is designed to provide a firing force between 35N and 60N when the canister is in the firing position, with a travel length ranging from 1 mm to 4 mm.
Furthermore, the inhaler includes features like a mouthpiece with a rotatable cap and a yoke engaging with a cam surface to facilitate canister movement. The device also incorporates a valve system that releases vacuum from the chamber upon inhalation, triggering the canister to move to the firing position. Additionally, the inhaler allows the metering chamber to fill with a predetermined dose of liquid from the drug reservoir when oriented correctly. With a focus on precise dosing and efficient delivery, the breath-actuated inhaler offers a user-friendly and effective solution for administering medication through inhalation.
