Abstract: A mouthpiece for a vaporizer device includes a vapor inlet and an aerosol outlet. A first plurality of air inlets and a second plurality of air inlets are disposed between the vapor inlet and the aerosol outlet and configured to provide air streams. The air streams form a first vortex and a second vortex. The air streams mix with a vapor entering from the vapor inlet and form an aerosol exiting through the aerosol outlet.

The electrical resistivity includes an electrical resistivity transition zone including an increase in electrical resistivity over a temperature range such that, when the PTCR heating element is heated to a first temperature within the transition zone, current flow from the power source is reduced to a level that limits further temperature increases of the PTCR heating element. Related apparatus, systems, techniques, and articles are also described.

Abstract: An aerosolization apparatus comprises a body defining a chamber having an air inlet and an air outlet. The chamber is sized to receive a receptacle containing a pharmaceutical formulation in a manner which allows the receptacle to move within the chamber. The chamber comprises a longitudinal axis, and the chamber has a cross-section orthogonal to its longitudinal axis that is non-circular. When a user inhales, air enters into the chamber through the inlet to cause the receptacle to move within the chamber so that the pharmaceutical formulation exits through an opening in the receptacle and is aerosolized for delivery to the user through the outlet.
