Intra-oral nebulizer
An improved nebulizer places a venturi in close proximity to or inside a patient's oral cavity. One or more medicine feed lines feeds the medicine to a location proximate to a venturi. A plurality of medicines may be administered simultaneously to the patient, with preferably each medicine vial being shape-keyed to a medicine receiver of corresponding shape. The medicine vial or vials may contain a standard unit dose of medication. A portable gas canister can be utilized to supply air pressure to the venturi when a press open release closed type valve is actuated.
1. A nebulizer comprising a main body and at least one medicine receiver configured to receive a medicine container, a mixing chamber and a venturi positioned to be located within the oral cavity of a patient when used and extending into the mixing chamber and connected to the medicine receiver and configured to receive medicine from the medicine receiver and air and mix the medicine and air in the mixing chamber, and a diffuser element positioned at the mixing chamber and configured to receive the flow of air from the venturi and cause the medication entering the mixing chamber to be atomized by the action of the air flowing through the venturi;
the nebulizer further containing a plurality of medicine receivers, each having a different shape, and each medicine receiver is shaped to match the shape uniquely associated with a different medicine container.
2. The nebulizer of claim 1 in which the at least one medicine receiver contains at least one puncture tube for piercing the medicine container.
3. The nebulizer of claim 2 in which the at least one puncture tube delivers medicine from the medicine container to a medicine feed line.
4. The nebulizer of claim 3 in which the medicine feed line delivers medicine to a location proximate to the venturi.
5. The nebulizer of claim 1 in which the medicine receiver is shaped to match a shape uniquely associated with medicine containers contain a particular medicine.
6. The nebulizer of claim 1 in which each medicine receiver communicates with a respective medicine feed line that delivers medicine to a location proximate to the venturi.
7. The nebulizer of claim 1 in which the medicine receiver receives a cup that can be manually filled with the medicine to be administered.
8. The nebulizer of claim 1 in which the medicine receiver receives a container containing a unit dose of medicine.
9. The nebulizer of claim 8 in which the unit dose is a standardized dose.
10. The nebulizer of claim 1 in which the venturi is provided with a source of gas from an air line.
11. The nebulizer of claim 1 in which the venture is provided with a source of gas from an attached gas canister.
12. The nebulizer of claim 11 in which application of the gas to the venture is activated by actuation of a valve.
13. The nebulizer of claim 1 in which the venturi and a medicine feed line communicate with a mixing chamber.
14. The nebulizer of claim 13 in which the mixing chamber contains a baffle.
15. The nebulizer of claim 13 in which the medicine exits from the mixing chamber by way of a plurality of small holes, sized to limit the maximum droplet size of the medication.
16. A nebulizer comprising:
a. a main body having at least an air line, a medicine line and a medicine receiver communicating with said medicine line;
b. a fluid air channel section connected to said main body having an air line and venturi, wherein the air line terminates in at said venturi and a medicine line connecting with the medicine line of the main body;
c. a fluid combiner and nozzle section and mixing chamber connected to said fluid air channel section, said venturi extending into said mixing chamber and permitting medicine from said medicine line to combine with air from the venturi in said mixing chamber, and
d. a diffuser positioned at the mixing chamber and connected to said fluid combiner and nozzle section and configured to receive the flow of air from the venturi and cause the medication entering the mixing chamber to be atomized by the action of air flowing through the venturi.
17. The nebulizer of claim 16 in which the air line is supplied by a portable gas container.
18. A method of administering a medicine to a patient using a nebulizer, comprising the step of nebulizing the medicine using a venturi placed within the patient's oral cavity, the nebulizer comprising a main body and at least one medicine receiver configured to receive a medicine container, a mixing chamber and a venturi positioned to be located within the oral cavity of a patient when used and extending into the mixing chamber and connected to the medicine receiver and configured to receive medicine from the medicine receiver and air and mix the medicine and air in the mixing chamber, and a diffuser element positioned at the mixing chamber and configured to receive the flow of air from the venturi and cause the medication entering the mixing chamber to be atomized by the action of the air flowing through the venturi.
