Claims44
An apparatus for delivery of a medicament to a respiratory system, the apparatus comprising:
- a reservoir for a liquid medicament for delivery to a respiratory system, the reservoir having a liquid medicament inlet port and a medicament outlet;
- an aerosol generator at the medicament outlet of the reservoir for aerosolizing the liquid medicament;
- and
- a connector for entraining the aerosolized medicament from the aerosol generator with a gas.
A connector for entraining an aerosolized medicament with a gas to deliver the medicament to a respiratory system, the connector comprising:
- a gas conduit having an inlet and an outlet;
- an aerosol supply conduit for delivering the aerosolized medicament into the gas conduit to entrain the aerosolized medicament with the gas;
- and
- a cap to selectively seal the aerosol supply conduit to maintain the pressure in the gas conduit when the connector is not in use.
A method of delivering a medicament to a respiratory system, the method comprising:
- providing a reservoir for a liquid medicament to be delivered to the respiratory system;
- delivering a volume of the liquid medicament into the reservoir;
- providing an aerosol generator for aerosolizing the liquid medicament;
- arranging the aerosol generator beneath the reservoir for gravitational flow of the liquid medicament from the reservoir to the aerosol generator;
- aerosolizing the liquid medicament;
- and
- delivering the aerosolized medicament to the respiratory system.
