Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
100 words
A nebulizer apparatus comprising a casing, inlet means and outlet means associated with said casing, nebulizer means adapted to produce a mist upon introduction of a fluid thereto, first and second fluid reservoirs associated with said casing, said first and second fluid reservoirs being normally in open communication with each other, tube means for normally withdrawing fluid from said first fluid reservoir to supply a first fluid to said nebulizer means, and means to block communication between first and second reservoirs whereby said tube means withdraws fluid from said second reservoir for supplying a second fluid to said nebulizer means.
Claim 2
Dependent Claim
100 words
A nebulizer apparatus comprising a casing, inlet means and outlet means associated with said casing, nebulizer means adapted to produce a mist upon introduction of a fluid thereto, first and second fluid reservoirs associated with said casing, said first and second fluid reservoirs being normally in open communication with each other, tube means for normally withdrawing fluid from said first fluid reservoir to supply a first fluid to said nebulizer means, and means to block communication between first and second reservoirs whereby said tube means withdraws fluid from said second reservoir for supplying a second fluid to said nebulizer means.
Claim 3
Dependent Claim
28 words
A nebulizer apparatus as set forth in claim 1 further including means to collect and return excess first fluid droplets from the mist to said first fluid reservoir;
Claim 4
Dependent Claim
28 words
A nebulizer apparatus as set forth in claim 2, further including means to collect and return excess second fluid droplets from the mist to said second fluid reservoir.
Claim 5
Dependent Claim
27 words
A nebulizer apparatus of claim 1 wherein said tube means comprises a downwardly extending flexible tube normally terminating adjacent the lowermost area of said first fluid reservoir.
Claim 6
Dependent Claim
51 words
A nebulizer apparatus of claim 4, said flexible tube being adapted to be removed from association with said first fluid and repositioned to withdraw a second fluid within said second fluid reservoir, and wherein said flexible tube thereby blocks fluid communication between said second fluid reservoir and said first fluid reservoir.
Claim 7
Dependent Claim
96 words
A high output nebulizer apparatus comprising an outer casing, inlet means and outlet means associated with said casing, a first fluid reservoir and a second fluid reservoir within said casing, nebulizer means disposed intermediate said inlet means and said outlet means for producing a mist upon the introduction of a fluid thereto from said respective reservoirs, means for effectively and independently introducing a first fluid and a second fluid to said nebulizer means, and means to collect and return excess droplets of first and second fluid from the mist to saiD respective first and second reservoirs.
Claim 8
Dependent Claim
96 words
A high output nebulizer apparatus comprising an outer casing, inlet means and outlet means associated with said casing, a first fluid reservoir and a second fluid reservoir within said casing, nebulizer means disposed intermediate said inlet means and said outlet means for producing a mist upon the introduction of a fluid thereto from said respective reservoirs, means for effectively and independently introducing a first fluid and a second fluid to said nebulizer means, and means to collect and return excess droplets of first and second fluid from the mist to saiD respective first and second reservoirs.
Claim 9
Dependent Claim
94 words
A nebulizer apparatus comprising a casing, inlet and outlet means associated with said casing, nebulizer means located intermediate said inlet and outlet means, said nebulizer means being adapted to produce a mist upon introduction of a fluid thereto, first and second fluid reservoirs within said casing for containing, respectively, a first and a second fluid, and means communicating with said nebulizer means for selectively and independently supplying fluid from either of said first and second fluid reservoirs whereby a mist may be produced having as a constituent either of the first or second fluids.
Claim 10
Dependent Claim
94 words
A nebulizer apparatus comprising a casing, inlet and outlet means associated with said casing, nebulizer means located intermediate said inlet and outlet means, said nebulizer means being adapted to produce a mist upon introduction of a fluid thereto, first and second fluid reservoirs within said casing for containing, respectively, a first and a second fluid, and means communicating with said nebulizer means for selectively and independently supplying fluid from either of said first and second fluid reservoirs whereby a mist may be produced having as a constituent either of the first or second fluids.
