Abstract

An apparatus for altering characteristics of a fluid. The apparatus includes a first perimeter wall defining an internal chamber therein. The first perimeter wall defines a first opening and a second opening therethrough. The first opening is constructed to be fluidly connected to a fluid source. The internal chamber defined in said first perimeter wall is constructed to contain a beneficial agent therein. A beneficial agent is disposed in the internal chamber defined in the first perimeter wall, the beneficial agent being dispersible in a fluid flowing from the first opening to the second opening through the internal chamber defined in the first perimeter wall.

Claims

1. An apparatus for altering characteristics of a fluid, said apparatus comprising:

a first canister including

a first perimeter wall defining first internal chamber therein, said first perimeter wall defining a first opening and a second opening therethrough, said first opening constructed for fluid connection to a fluid source;

a second canister including

a second perimeter wall defining a second internal chamber therein, said second perimeter wall defining a first opening and a second opening therethrough, said second canister constructed to be mechanically connected to said first canister, said first and second perimeter walls defining a flow path therethrough from said first opening defined through said first perimeter wall to said second opening defined through said second perimeter wall when said first canister and said second canister are mechanically connected together;

at least one of said first internal chamber and said second internal chamber constructed to contain a beneficial agent therein; and

a beneficial agent disposed in said internal chamber that is constructed to contain the beneficial agent, said beneficial agent being dispersible in a fluid flowing from said first opening of the first canister to said second opening of said second canister.

2. An apparatus for altering characteristics of a fluid in accordance with claim 1, wherein the beneficial agent is disposed in said first internal chamber, said apparatus further comprising:

a frangible membrane covering said second opening defined through said first perimeter wall, said frangible membrane constructed to retain said beneficial agent in said first internal chamber.

3. An apparatus for altering characteristics of a fluid in accordance with claim 2, wherein said apparatus further comprises:

a piercing member mounted on said second canister proximate said first opening defined through said second perimeter wall, said piercing member constructed to pierce said frangible membrane covering said second opening defined through said first perimeter wall when said first and second canisters are mechanically connected together.

4. An apparatus for altering characteristics of a fluid in accordance with claim 1, wherein said first perimeter wall defines a first thread thereon and said second perimeter wall defines a second thread thereon, said first and second threads being complementary to mechanically connect said first and second canisters together.

5. An apparatus for altering characteristics of a fluid in accordance with claim 1, wherein said first perimeter wall and said second perimeter wall are constructed to be snap fit to one another to mechanically connect said first and second canisters together.

6. An apparatus for altering characteristics of a fluid in accordance with claim 1, wherein said apparatus further comprises:

a spike constructed to be mounted on said first perimeter wall, said spike defining a channel therethrough for fluid communication with said first internal chamber through said first opening defined through said first perimeter wall when the spike is mounted thereon, said spike constructed to pierce a pierceable seal of a fluid source.

7. An apparatus for altering characteristics of a fluid in accordance with claim 1, wherein said second canister is constructed to be connected to an apparatus for delivering fluid to a patient.

8. An apparatus for altering characteristics of a fluid in accordance with claim 1, wherein said internal chamber that is constructed to contain a beneficial agent includes a transverse wall having at least one aperture therethrough to divide said internal chamber that is constructed to contain a beneficial agent into separate chamber portions.

9. An apparatus for altering characteristics of a fluid, said apparatus comprising:

a first canister having a first perimeter wall, said first perimeter wall defining a first internal chamber therein, said first internal chamber constructed to contain a beneficial agent therein, said first perimeter wall defining first and second openings therethrough;

a frangible membrane covering said second opening defined through said first perimeter wall of said first canister;

a first beneficial agent disposed in said first internal chamber defined by said first perimeter wall of said first canister;

a second canister having a second perimeter wall, said second perimeter wall defining a second internal chamber therein, said second internal chamber constructed to contain a second beneficial agent therein, said second perimeter wall defining first and second openings therethrough;

a piercing member mounted on said second canister, said piercing member constructed to pierce said frangible membrane covering said second opening defined through said first perimeter wall of said first canister;

said first and second canisters constructed to be mechanically connected to one another.

10. An apparatus for altering characteristics of a fluid in accordance with claim 9, wherein said first canister is constructed to be connected to a source of a fluid whereby fluid from said source can flow through said first opening defined by said first perimeter wall, and wherein said second canister is constructed to be connected to an apparatus for delivering fluid to a patient, whereby fluid can flow from a fluid source through said first and second internal chambers and into an apparatus for delivering fluid to a patient.

11. An apparatus for altering characteristics of a fluid in accordance with claim 9, said apparatus further comprising a spike constructed to be mounted on said first canister, said spike defining a channel therethrough for fluid communication with said first internal chamber through said first opening defined through said first perimeter wall.

12. An apparatus for altering characteristics of a fluid in accordance with claim 9, wherein at least one of said first internal chamber and said second internal chamber includes a transverse wall having at least one aperture therethrough to divide said at least one internal chamber into separate chamber portions.
