Abstract

The invention relates to a small-volume nebulizer that is pre-filled with at least one unit-dose of medicine and hermetically sealed until use. The nebulizer may be sealed at the top with a removable cap that may be detached at the time of use and replaced with a patient connector. Likewise, the nebulizer may be sealed at the bottom with a bottom cap that is replaced with a gas source at the beginning of a therapeutic aerosol treatment.

Claims

1. A sterilized, pre-filled, small-volume nebulizer ready for a patient to administer for respiratory care comprising:

a small-volume nebulizer body comprising a housing top having an outlet opening and a baffle and a housing bottom having an inlet opening;

a siphon and jet component contained within said small-volume nebulizer body between said inlet opening and said baffle;

a first cap sealing said outlet opening;

a second cap sealing said inlet opening;

a unit-dose of medication contained within said small-volume nebulizer body,

wherein said small-volume nebulizer body and said siphon and jet component were sterilized; and

wherein said first cap and said second cap prevent said unit-dose of medication from spilling from said small-volume nebulizer body by sealing all openings in said small-volume nebulizer body.

2. The sterilized, pre-filled, small-volume nebulizer according to claim 1, further comprising a means for preventing egress of said unit-dose of medication through said inlet opening.

3. The sterilized, pre-filled, small-volume nebulizer according to claim 1, further comprising a means of preventing retrograde movement into said nebulizer body.

4. The sterilized, pre-filled, small-volume nebulizer according to claim 1, further comprising a plurality of said unit-doses of medication.

5. The sterilized, pre-filled, small-volume nebulizer according to claim 4, further comprising unit-dose completion demarcation marks.

6. The sterilized, pre-filled, small-volume nebulizer according to claim 1, wherein said first cap is comprised of a piercable seal.

7. The sterilized, pre-filled, small-volume nebulizer according to claim 1, wherein said housing top is attached to said housing bottom by a hermetic seal and wherein said hermetic seal, said first cap and said second cap prevent said unit-dose of medication from spilling from said small-volume nebulizer body.

8. A method for creating a sterilized small-volume nebulizer pre-filled with medicine ready for a patient to administer comprising the steps of:

sterilizing said small-volume nebulizer'"'"'s components including a housing top, a housing bottom, a siphon, a jet, a baffle, inlet cap and outlet cap, wherein said housing top includes an outlet port sealed by said outlet cap and said housing bottom includes an inlet port sealed by said inlet cap;

filling said housing bottom with at least one unit-dose of medicine; and

connecting said housing top to said housing bottom with a hermetic seal to form a nebulizer body having said siphon, said jet, said baffle and said unit-dose of medicine sealed within said nebulizer body, wherein all openings of said nebulizer body are sealed by said inlet cap, said outlet cap and said hermetic seal.

9. The method of claim 8 wherein said baffle is part of said housing top, and said siphon and said jet are a single piece, which is placed in said housing bottom prior to connecting said housing top to said housing bottom.

10. The method of claim 8 wherein said outlet port is cylindrical having an outside diameter between 15 and 30 millimeters.

11. A pre-filled, small-volume jet nebulizer ready for a patient to administer for respiratory care comprising:

a small-volume nebulizer body consisting of a housing, a baffle, an outlet opening and an inlet opening;

a siphon and a jet contained within said small-volume nebulizer body;

a first cap sealing said outlet opening;

a second cap sealing said inlet opening; and

a unit-dose of medication sealed within said small-volume nebulizer body by said first cap and said second cap.

12. The pre-filled, small-volume jet nebulizer according to claim 11, further comprising a means for preventing egress of said unit-dose of medication through said inlet opening.

13. The pre-filled, small-volume jet nebulizer according to claim 11, wherein said unit-dose of medication is a first component of a multi-component medication, and said pre-filled, small-volume jet nebulizer further includes a compartment containing a second component of said multi-component medication.

14. The pre-filled, small-volume jet nebulizer according to claim 11, further comprising one or more labels identifying said unit-dose of medication.

15. The pre-filled, small-volume jet nebulizer according to claim 11, further comprising a means of preventing retrograde movement into said housing.

16. The pre-filled, small-volume jet nebulizer according to claim 11, further comprising multiple said unit-doses of medication.

17. The pre-filled, small-volume jet nebulizer according to claim 16, further comprising unit-dose completion demarcation marks.

18. The pre-filled, small-volume jet nebulizer according to claim 11, wherein said first cap is comprised of a piercable seal.

19. The pre-filled, small-volume jet nebulizer according to claim 11, wherein said housing comprises a housing bottom, a housing top and a hermetic seal created between said housing bottom and said housing top.

20. The pre-filled, small-volume jet nebulizer according to claim 19, wherein said hermetic seal, said first cap and said second cap prevent said unit-dose of medication from spilling from said small-volume nebulizer body.
