LIQUID DRUG CARTRIDGES AND ASSOCIATED DISPENSER

摘要

Liquid drug cartridges and an associated inhaler are used to deliver one more separate doses of an aerosolized liquid drug. A cartridge includes a container for storing the liquid drug, an end cap having an ejection opening, a filter element, and a piston that is repositionable relative to the container to selectively eject a volume of liquid drug from the ejection opening. The filter element filters the liquid drug prior to ejection from the ejection opening. The liquid drug cartridge can be coupled with an inhaler that includes an aerosol generator. The aerosol generator includes a vibratable membrane onto which the liquid drug is ejected. The liquid drug is aerosolized by the vibration of the membrane for inhalation by a user.

1. A liquid drug cartridge, comprising:
a container configured to store a liquid drug; an end cap coupled with a first end of the container, the end cap having an ejection opening from which a volume of the liquid drug from the container can be selectively ejected; a filter element configured to filter the liquid drug prior to ejection from the ejection opening; and a piston sealing a second end of the container, the piston being repositionable relative to the container so as to selectively eject a volume of the liquid drug from the container via the ejection opening.
