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.
Core Innovation
A device for delivery of a composition to an airway of a subject is described with a gas inlet, a gas outlet, a composition receptacle comprising a composition capsule containing the composition, and a dispersion chamber. The device delivers the composition to the airway via fluid communication between the gas inlet, the composition receptacle, and the dispersion chamber, with output through the gas outlet and mouthpiece for airway delivery.
The device includes one or more primers, each comprising a cam follower and an associated pin or blade. A cap covers the gas outlet and comprises one or more cams which are located so as to engage with and displace a respective one of the one or more primers to pierce the composition capsule upon removal of the cap. The composition capsule is held in place for piercing by the one or more primers between a capsule seat formed in a base of the device and one or more elongate members extending from the cap.
The dispersion chamber receives the gas and a pierced or cut composition capsule, with optional features for dispersion including a vortex chamber and protrusions to promote capsule spinning, and an optional deagglomerator adjacent to the dispersion chamber. The document also describes dispensing as inhalation-driven or pressure-driven capsule movement and dispersion, including variants for positive pressure insufflation with a piston first configuration and second configuration, and negative-pressure-only single-sided operation.
Claims Coverage
The independent claim covers an automatic respiratory particulate delivery device that uses gas flow and a dispersion chamber, combined with a cap-driven piercing mechanism using cam followers and pins or blades, and controlled capsule positioning between a capsule seat and elongate members extending from the cap.
Airway delivery with gas inlet and gas outlet to dispersion chamber
A device for delivery of a composition to an airway of a subject comprising in fluid communication a gas inlet, a gas outlet, a composition receptacle comprising a composition capsule containing the composition, and a dispersion chamber.
Cap-driven piercing using cams that engage cam followers
A cap configured to cover the gas outlet and comprising one or more cams located so as to engage with and displace a respective one of the one or more primers to pierce the composition capsule upon removal of the cap.
Primers comprising cam follower with associated pin or blade
One or more primers each comprising a cam follower and an associated pin or blade.
Capsule held between capsule seat and elongate members for piercing
The composition capsule is held in place for piercing by the one or more primers between a capsule seat formed in a base of the device and one or more elongate members which extend from the cap.
Inhalation through the gas outlet drives gas flow to move the capsule
Inhalation through the gas outlet by a subject drives gas flow from the gas inlet, thereby moving the composition capsule from the composition receptacle to the dispersion chamber.
Overall claim coverage centers on an airway delivery device that couples gas-flow dispersion with an automatic cap-removal piercing mechanism. The core inventive aspects are the primer structure, cap cams that displace primers to pierce the composition capsule upon removal, and capsule positioning between a capsule seat and elongate members extending from the cap.
