The assembly further includes a metered dose inhaler adapter for connecting the medication inlet port to an external source of aerosolized medication to permit the administration of the aerosolized medication to a patient through the connector tube. The assembly also has a releasable cap for closing the medication inlet port during non-use. ## Claims ### Claim 1 A treatment non-rebreather assembly for the separate and simultaneous administration of oxygen and an aerosolized medication to a patient, comprising: (a) a hollow connector tube including (i) a transport body having one end and an opposite end and one side portion and another side portion, said transport body defining a passageway extending between said one and opposite ends, (ii) an oxygen inlet port formed at said one side portion of said body, (iii) an aerosolized medication inlet port formed at said another side portion of said body, (iv) a reservoir port formed at said one end of said body for connecting to a reservoir bag, (v) a patient outlet port formed at said opposite end of said body for connecting to means for attaching said assembly to a patient, and (vi) a single one-way inhalation valve located across said passageway of said transport body between said oxygen inlet port and said medication inlet port and adapted to limit direction of flow to being from said reservoir port toward said patient outlet port; (b) means for connecting said medication inlet port to an external source of an aerosolized medication to permit the delivery of the aerosolized medication to a patient through said connector tube; and (c) means for closing said medication inlet port during the non-use of said port. ### Claim 2 (depends on 1) The assembly of claim 1 wherein said oxygen inlet port is positioned closer to said reservoir port on said connector tube than to said patient outlet port thereon and said medication inlet port is positioned closer to said patient outlet port on said connector tube than to said reservoir port thereon so as to prevent opposing flows from said oxygen inlet port and said medication inlet port from obstructing one another. ### Claim 3 (depends on 1) The assembly of claim 1 wherein said oxygen inlet port is positioned closer to said reservoir port on said connector tube than to said patient outlet port thereon such that oxygen arriving from said oxygen inlet port tends to flow to said reservoir port. ### Claim 4 (depends on 1) The assembly of claim 1 wherein said medication inlet port is positioned closer to said patient outlet port on said connector tube than to said reservoir port thereon such that said aerosolized medication arriving from said medication inlet port tends to go directly to the patient. ### Claim 5 (depends on 1) The assembly of claim 1 wherein said means for connecting said medication inlet port to the external source of aerosolized medication is a flexible tubing. ### Claim 6 (depends on 1) The assembly of claim 1 wherein said means for connecting said medication inlet port to the external source of aerosolized medication is a hollow elongated sleeve having means for gripping with fingers and being connectable to said medication inlet port to permit the delivery of an aerosolized medication to a patient through said connector tube. ### Claim 7 (depends on 6) The assembly of claim 6 wherein said means for gripping said sleeve is a pair of tabs attached to and projecting from opposite sides of said sleeve. ### Claim 8 (depends on 7) The assembly of claim 7 wherein said pair of tabs is located closer to one end than to a opposite end of said sleeve. ### Claim 9 (depends on 1) The assembly of claim 1 wherein said means for closing said medication inlet port during non-use of said port is a releasable cap attached to said port to fit over said port opening. ### Claim 10 (depends on 9) The assembly of claim 9 wherein said cap is secured to the outside of said medication inlet port by a ring that is fitted around said port which holds said cap when said port is in use. ### Claim 11 A treatment non-rebreather assembly for the separate and simultaneous administration of oxygen and an aerosolized medication to a patient, comprising: (a) a hollow connector tube including (i) a transport body having one end and an opposite end and one side portion and another side portion, said transport body defining a passageway extending between said one and opposite ends, (ii) an oxygen inlet port formed at said one side portion of said body, (iii) an aerosolized medication inlet port formed at said another side portion of said body, (iv) a reservoir port formed at said one end of said body for connecting to a reservoir bag, (v) a patient outlet port formed at said opposite end of said body for connecting to means for attaching said assembly to a patient, and (vi) a pair of one-way inhalation valves, a first of said valves being located across said passageway of said transport body between said oxygen inlet port and said medication inlet port and adapted to limit direction of flow to being from said reservoir port toward said patient outlet port, a second of said valves being located at said medication inlet port and adapted to limit direction of flow to being into said transport body through said medication inlet port; (b) means for connecting said medication inlet port to an external source of an aerosolized medication to permit the delivery of the aerosolized medication to a patient through said connector tube; and (c) means for closing said medication inlet port during the non-use of said port. ### Claim 12 (depends on 11) The assembly of claim 11 wherein said oxygen inlet port is positioned closer to said reservoir port on said connector tube than to said patient outlet port thereon and said medication inlet port is positioned closer to said patient outlet port on said connector tube than to said reservoir port thereon so as to prevent opposing flows from said oxygen inlet port and said medication inlet port from obstructing one another. ### Claim 13 A treatment non-rebreather assembly for the separate and simultaneous administration of oxygen and an aerosolized medication to a patient, comprising: (a) a hollow connector tube including (i) a transport body having one end and an opposite end and one side portion and another side portion, said transport body defining a passageway extending between said one and opposite ends, (ii) an oxygen inlet port formed at said one side portion of said transport body and opening into said passageway, (iii) an aerosolized medication inlet port formed at said another side portion of said transport body and opening into said passageway, (iv) a reservoir port forming an opening at said one end of said transport body for connecting said passageway thereof in communication with an external reservoir bag, and (v) a patient outlet port forming an opening at said opposite end of said transport body for connecting said passageway thereof to means for attaching said assembly to a patient; (b) means for connecting said medication inlet port to an external source of an aerosolized medication to permit the delivery of the aerosolized medication to a patient through said connector tube; and (c) means for closing said medication inlet port during the non-use of said port. ### Claim 14 (depends on 13) The assembly of claim 13 wherein said oxygen inlet port is positioned closer to said reservoir port on said connector tube than to said patient outlet port thereon and said medication inlet port is positioned closer to said patient outlet port on said connector tube than to said reservoir port thereon so as to prevent opposing flows from said oxygen inlet port and said medication inlet port from obstructing one another. ### Claim 15 (depends on 13) The assembly of claim 13 wherein said oxygen inlet port is positioned closer to said reservoir port on said connector tube than to said patient outlet port thereon such that oxygen arriving from said oxygen inlet port tends to flow to said reservoir port. ### Claim 16 (depends on 13) The assembly of claim 13 wherein said medication inlet port is positioned closer to said patient outlet port on said connector tube than to said reservoir port thereon such that said aerosolized medication arriving from said medication inlet port tends to go directly to the patient.
