Abstract: An aerosol generating assembly is disclosed, which includes a heater assembly including, a heater body extending in a longitudinal direction, and at least one heater in the heater body; a capillary tube extending longitudinally through at least a portion of the heater body, the capillary tube in fluid communication with a reservoir, the at least one heater configured to heat the capillary tube; a thermocouple in the heater body; and a temperature controller configured to control a heating temperature.

Abstract: A drug delivery system, which includes an aerosol generator unit, a pumping unit, a flow tube, at least one condensate collector and an aerosol transition adapter. The aerosol generator forms an aerosol from a liquid formulation, which is partially volatilized. The pumping unit supplies the liquid formulation to the aerosol generator unit and a flow tube having an inlet end in fluid communication with an outlet of the aerosol generator unit and an outlet adapted for connection to a patient interface, which supplies ventilation gas to a patient's lungs. The system also includes at least one condensate collector adapted to collect condensed liquid or liquid produced by the aerosol generator unit, and a transition adapter arranged to mix aerosol produced by the aerosol generator unit with heated air or ventilation gas and direct the mixed aerosol into the inlet end of the flow passage.

Abstract: An aerosol generation system having an aerosol generator wherein a liquid formulation is at least partially volatilized in a capillary passage and discharged from the capillary passage to form an aerosol. The aerosol generation system includes a pumping unit adapted to supply a liquid formulation to the aerosol generator; and a fluidic element located between the pumping unit and the capillary passage of the aerosol generator, wherein the fluidic element increases backpressure of the liquid formulation as the liquid formulation enters the capillary passage of the aerosol generator.

Abstract: A piston pump delivers precise and repeatable volumes of a fluid from a reservoir to a downstream component, and includes a piston that is rotatably and reciprocally mounted within a cylinder. The outer periphery of the piston forms an interference fit with the inner periphery of the cylinder. At least one groove is formed in the outer periphery of the piston, with the groove defining a precise volume between the piston and the cylinder, and extending in an axial direction of the piston. The cylinder includes an inlet port for providing fluid communication between a reservoir and the at least one groove when the piston is in a first position, and an exit port circumferentially spaced from the inlet port for providing fluid communication between the at least one groove and a downstream component when the first piston is rotated to a second position where the at least one groove is aligned with the exit port.

Abstract: A centrifugal separator for removal of impurities from gases, including deflecting means in an inlet region of the housing of the separator, said deflecting means comprising a central circular body and a plurality of vanes extending from the periphery of said body and having portions bent to extend away from the inlet so as to deflect gases when passed thereover and create a vortex flow in the housing; each of said vanes, prior to the deflecting portion being bent into the deflecting position, including a first outer, arcuate peripheral edge, a second inwardly extending edge running from one end of said outer edge and leading to a third inner arcuate edge extending substantially concentrically and over the same arc as a portion of said outer edge; and a fourth, inwardly extending edge running from the other end of said outer edge and leading to said central body; outer portions of said vanes which include portions of said first and second edges being locatable in the seating means of the separator housing.
