Abstract
A device for inhaling an active agent is provided that can be moved from a first configuration to a second configuration. The device comprises two flexible substrates and a membrane located between the two flexible substrates, and the two flexible substrates being connected at two opposing edges and unconnected at two further opposing edges. An active agent provided on the membrane may be inhaled by a user when the device is in the second configuration.
Claims18
An inhaler, comprising:
- two flexible substrates connected at first two opposing edges that extend along a length of the two flexible substrates and unconnected at second two opposing edges that meet the first two opposing edges such that the two flexible substrates are movable between a first configuration where the two flexible substrates are substantially flat and in contact with one another and a second configuration where the two flexible substrates are flexed such that a channel forms between the two flexible substrates, extends along the length thereof, and opens at the second two opposing edges;
- and
- a membrane mounted between the two flexible substrates in the channel within an opening positioned in a reduced portion of the channel, the reduced portion having the smallest cross-section of the channel and configured to restrict air flow through the channel to increase a rate of air flow through the membrane and a force exerted by the air flow on an active agent on the membrane to lift the active agent from the membrane and into the air flow when the inhaler is in the second configuration such that the active agent disposed on the membrane may be inhaled by a user when the inhaler is in the second configuration.
