ABSTRACT:
A nebulizer is provided which includes a liquid container and a cap attachable thereto. The cap includes a outlet port for delivery of a nebulized liquid/gas mixture to a patient, a gas inlet, a venturi in communication with the gas inlet, a conduit through which liquid may be circulated in the cap and heated by an external heater, a liquid outlet adjacent the end of the venturi, so that the gas flowing through the venturi draws out the liquid, and a dial rotatable on the cap. The dial has windows which may be positioned over openings in the cap to allow air from the environment to enter the cap and dilute the gas to a desired concentration. The dial engages the cap securely once its position is set on the cap, so the gas concentration is not inadvertently changed during use of the nebulizer.
