Abstract

Предлагаются системы и способы для изоляции и/или обезвоживания участка тракта доставки лекарства устройства для доставки лекарства, чтобы уменьшать содержание водяного пара в нем. Например, предлагается дозирующий ингалятор для доставки аэрозолизированного лекарственного препарата или другого вещества пользователю. Аэрозолизированный лекарственный препарат или другое вещество могут выпускаться из выпускного прохода внутри ингалятора в ингаляционный канал для ингаляции пользователем, и ингалятор может содержать уплотнительный элемент, предназначенный для селективной изоляции выпускного прохода от ингаляционного канала и внешней среды в нерабочий период. Ингалятор может дополнительно содержать влагопоглотитель, предназначенный для удаления влаги из изолированного выпускного прохода. В других случаях, влагопоглотитель может быть выполнен с возможностью удаления влаги из выпускного прохода ингалятора, без изоляции выпускного прохода в нерабочий период.Systems and methods are provided for isolating and / or dehydrating a portion of the drug delivery tract of a drug delivery device to reduce its water vapor content. For example, a metered-dose inhaler is provided for delivering an aerosolized drug or other substance to a user. An aerosolized drug or other substance may be discharged from an outlet within the inhaler into an inhalation passage for inhalation by a user, and the inhaler may include a sealing element for selectively isolating the outlet passage from the inhalation passage and the external environment during non-operation periods. The inhaler may further comprise a desiccant for removing moisture from the isolated outlet passage. In other cases, the desiccant can be configured to remove moisture from the outlet of the inhaler, without isolating the outlet during non-operation.
