Abstract
A nebulizer and heater system for delivering a heated aerosol spray to a patient. The nebulizer includes a nebulization chamber where an aerosol spray is formed and a subsequent heating chamber. Large liquid particles are collected in a well formed in the heating chamber. The heater is configured such that it can easily be joined to and removed from the nebulizer. The heater has a heating rod which extends into the well and heats the liquid collected therein. The heated liquid, in turn, heats the aerosol as it passes through the heating chamber.
