Abstract
The present invention provides a particulate delivery device with an automatic activation mechanism that pierces or cuts a composition capsule when a cap is removed. The cap cannot be replaced once the device is activated for use. The device allows for gas flow through the device from a gas inlet to a gas outlet through a composition receptacle and dispersion chamber to deliver particulate to the airway of a subject.
Claims14
A device for delivery of a composition to an airway of a subject, the device comprising:
- in fluid communication:
- a gas inlet;
- a gas outlet;
- a composition receptacle comprising a composition capsule containing the composition;
- and
- a dispersion chamber;
- and
- one or more primers each comprising a cam follower and an associated pin or blade;
- and
- a cap comprising one or more cams which are located so as to engage with and displace the respective primer to pierce the composition capsule upon removal of the cap,
- wherein the cam follower of each of the one or more primers prevents the cap from being replaced once removed.
