Abstract: An aerosol delivery system has a nebulizer and a humidifier providing a gas flow to the nebulizer. A controller varies humidity level of the gas flow to the nebulizer so that if the nebulizer is not operating it has about 100% humidity and it is operating the value is less to allow for the humidification effect of the nebulizer. The control may be achieved by dynamically varying proportions of flow through a dry branch and a humidification branch.

Abstract: A nebuliser control device has a manually adjustable user interface and a cable extending from the interface to a power source, and a cable extending from the interface to an aerosol generator. The interface is manually adjustable by physical movement of an actuator such a slider or a rotating knob to locally control the operation of the aerosol generator.

Abstract: A nebulizer device has an aerosol generator mounted in a housing, and a mouthpiece. The device is adapted for delivery of an active agent in an aerosol into the buccal cavity, with droplet size greater than 10 ?m. Aerosolization is started at or after the end of breath inhalation and is stopped at or before the start of breath inhalation. The flow is via mouthpiece with internal ridges which periodically narrow the flow path volume to so that droplets coalesce in the flow path before the mesh.

Abstract: The present invention concerns an improved bioreactor with enhanced oxygen transfer. In lieu of the standard impeller and sparger assembly, a rotating gas sparger is used to introduce oxygen into the reactor. A mechanical drive shaft is coupled to a conduit from which a length of tubing extends. A source of pressurized gas is fluidly coupled to the tubing, which tubing is rotated via the mechanical drive shaft. The rotating tubing has a variably sized outlet for introducing oxygen bubbles into the liquid medium of the reactor, the bubbles providing both mechanical agitation and oxygen transfer due to the rotation of the tubing.
