Dual chamber nebulizer apparatus

A dual chamber nebulizer apparatus for atomizing a first and second liquid medicine and for administering the atomized medicine, comprising:

• a housing having a first chamber for holding the first liquid medicine and a second chamber for holding the second liquid medicine, said housing having a barrier wall that separates said first chamber from said second chamber;
• an atomizer member situated in an upper portion of said housing and configured to atomize liquid into vapor;
• a flow member coupled to said housing and in fluid communication with said atomizer member, said flow member having an inlet port selectively directing a compressed air flow to said atomizer member;
• a first aspiration tube having a proximal end in fluid communication with said atomizer member and a distal end extending into said first chamber, said first aspiration tube being perpendicular to said atomizer member;
• a second aspiration tube having a proximal end in fluid communication with said atomizer member and a distal end extending into said second chamber, said second aspiration tube being perpendicular to said atomizer member;
• wherein:
• said atomizer member, said flow member, and said first and second aspiration tubes collectively form a junction that is operable to draw the first and second liquid medicines from said first and second medicine chambers via said first and second aspiration tubes, respectively, into said atomizer member where the compressed air flow atomizes the first and second liquid medicines;
• said atomizer member has a tubular configuration defining an interior area having opposed closed ends, each closed end defining a channel connecting the interior area with ambient air outside said atomizer assembly;
• said atomizer member includes a pair of baffles mounted externally to said opposed closed ends, respectively, of said atomizer member, said pair of baffles being positioned in alignment with said channels of said closed ends, respectively, and displaced therefrom, whereby the compressed airflow carrying the atomized first and second liquid medicines impacts said pair of baffles after passing through said channels, respectively.

• a delivery member having a proximal end coupled to an upper end of said housing and in fluid communication with said atomizer member for receiving said atomized first and second medicines and a distal end displaced from said housing;
• wherein said delivery member includes an outlet port situated at said distal end;
• a refill assembly having an inner end coupled to a distal end of said flow member and an outer end opposite said inner end and situated outside of said housing, said refill assembly including a body portion having a tubular configuration and extending between said inner and outer ends;
• wherein said delivery member is constructed of flexible tubing that is selectively shaped to extend away from said housing in any direction.
