INTRA-ORAL NEBULIZER ACTIVATED BY NEGATIVE INSPIRATORY PRESSURE

摘要

A medication reservoir is contained within a nebulizer body. An air line includes a distal end within the nebulizer body and venturi nozzle. A medication suction line extends from the medication reservoir to the venturi nozzle through which medication is drawn upward and mixed with air after passing through the venturi nozzle and nebulized for discharge through the nebulizer outlet. A valve is positioned within the air line proximal to the venturi nozzle and normally configured in a closed position until a negative inspiratory pressure is applied by a user to open the valve and allow air through the air line and venturi nozzle from a source of air and draw medication upward through the medication suction line for nebulization and discharge through the nebulizer outlet.
