Abstract
Abstract A dual passage adapter for providing an inlet-outlet port system that couples a medical liquid bottle to a medical gas source. The adapter has a snap lock feature which permanently connects it to the medical liquid bottle so the adapter can be used with only one bottle to reduce risk of cross-contamination among patients. Gas and liquid are mixed in the bottle and exit through the adapter as humidified gas which a patient breathes during inhalation therapy.
