A nebulizer which includes a housing having a vertical axis, an open bottom, an air inlet tube extending into the housing and an outlet tube extending from the housing. A bottom cup is removably attached to the open bottom for storing liquid medication, the bottom cup having an opening therethrough. Pressurized air is supplied through the bottom cup opening into the housing and a capillary tube extends from the cup to the air supply so that liquid medication will be drawn up through the capillary tube to form droplets. An axial cylindrical chimney is receivable inside the housing, the chimney having an annular flange extending perpendicularly from the chimney, the flange capable of resting against the housing. The chimney includes a removable check valve at the top thereof. A horizontal target extends across the cylindrical chimney, whereby the air supply and liquid droplets will impinge on the horizontal target and impinge on the check valve, the droplets being broken into micron size droplets for delivery to a patient. |
