Abstract

In accordance with non-limiting examples, a nebulizer includes a main body comprising an air channel section and further comprising a mixing chamber and a venturi positioned to be placed within the patient'"'"'s oral cavity and configured to receive medicine and air and mix the medicine and air within the mixing chamber and receive the air flow through the venturi and cause the medicine entering the mixing chamber to be atomized by the action of air flowing through the venturi. An air flow sensor is associated with the main body and configured to measure the air flow created by the patient'"'"'s one of at least inhaling and exhaling air.

Claims

1. A nebulizer, comprising:

a nebulizer body comprising

a gas channel that receives a flow of gas;

a medicine feed that receives medicine; and

a nebulizer outlet configured to be received within the oral cavity of a patient;

a mixing chamber formed within the nebulizer body;

a longitudinally extending venturi connected to the gas channel and having a venturi outlet at the mixing chamber and the medicine feed terminating thereat, wherein said venturi is configured to be oriented horizontally and located within the oral cavity of a patient when the nebulizer is in use and to receive and mix the medicine and gas at the venturi outlet and within the mixing chamber and to atomize the medicine by the action of gas flowing through the venturi and into the mixing chamber during nebulization and exit the nebulizer outlet into the oral cavity of the patient.

2. The nebulizer according to claim 1, and further comprising at least one medicine receiver contained on the nebulizer body and connected to said medicine feed to deliver medicine within the medicine feed.

3. The nebulizer according to claim 2, wherein the at least one medicine receiver is configured to receive a unit dosage of medicine.

4. The nebulizer according to claim 2, and further comprising a plurality of medicine receivers carried by the nebulizer body, each medicine receiver containing a different medicine.

5. The nebulizer according to claim 4, wherein a plurality of medicines are administered simultaneously.

6. The nebulizer according to claim 4, wherein each medicine receiver is shaped to correspond to different medicines.

7. The nebulizer according to claim 1, and further comprising air curtain conduits that are configured to supply a curtain of air above and below the nebulized medicine and gas to enhance penetration of nebulized medicine into the airway of the patient.

8. The nebulizer according to claim 1, wherein said gas comprises compressed air.

9. The nebulizer according to claim 1, further comprising an air flow sensor positioned at the nebulizer outlet and configured to measure the air flow created by the patient'"'"'s one of at least inhaling and exhaling air.

10. A nebulizer, comprising:

a nebulizer body configured to be grasped by a user and comprising

a canister port and a gas channel in communication therewith that receives a flow of gas from a gas canister attached to the canister port;

a valve positioned at the canister port and actuable to allow a metered amount of compressed gas to flow from the gas canister and through the gas channel and venturi;

at least one medicine receiver;

a medicine feed connected to the at least one medicine receiver that receives medicine from the at least one medicine receiver; and

a nebulizer outlet configured to be received within the oral cavity of a patient;

a mixing chamber formed within the nebulizer body; and

a longitudinally extending venturi connected to the gas channel and having a venturi outlet at the mixing chamber and the medicine feed terminating thereat, wherein said venturi is configured to be oriented horizontally and located within the oral cavity of a patient when the nebulizer is in use and to receive and mix a predetermined amount of medicine and gas at the venturi outlet and within the mixing chamber and to atomize the medicine by the action of gas flowing through the venturi and into the mixing chamber during nebulization and exit the nebulizer outlet into the oral cavity of the patient.

11. The nebulizer according to claim 10, wherein the at least one medicine receiver is configured to receive a unit dosage of medicine.

12. The nebulizer according to claim 10, and further comprising a plurality of medicine receivers carried by the nebulizer body, each medicine receiver containing a different medicine.

13. The nebulizer according to claim 12, wherein a plurality of medicines are administered simultaneously.

14. The nebulizer according to claim 12, wherein each medicine receiver is shaped to match a shape uniquely associated with a different medicine.

15. The nebulizer according to claim 10, and further comprising air curtain conduits that are configured to supply a curtain of air above and below the nebulized medicine and gas to enhance penetration of nebulized medicine into the airway of the patient.

16. The nebulizer according to claim 10, further comprising an air flow sensor positioned at the nebulizer outlet and configured to measure the air flow created by the patient'"'"'s one of at least inhaling and exhaling air.

17. A nebulizer, comprising:

a nebulizer body configured to be grasped by a user and comprising

a canister port and a gas channel in communication therewith that receives a flow of gas from a gas canister attached to the canister port;

a valve positioned at the canister port and actuable to allow a metered amount of compressed gas to flow from the gas canister and through the gas channel and venturi;

a plurality of medicine receivers positioned on the nebulizer body and each medicine receiver containing a different medicine;

a medicine feed connected to the plurality of medicine receivers that receives medicine from a selected number of medicine receivers such that a one or a plurality of medicines are received simultaneously into the medicine feed; and

a nebulizer outlet configured to be received within the oral cavity of a patient;

a mixing chamber formed within the nebulizer body; and

a longitudinally extending venturi connected to the gas channel and having a venturi outlet at the mixing chamber and the medicine feed terminating thereat, wherein said venturi is configured to be oriented horizontally and located within the oral cavity of a patient when the nebulizer is in use and to receive and mix a predetermined amount of gas and one or a plurality of medicines at the venturi outlet and within the mixing chamber and to atomize the medicine by the action of gas flowing through the venturi and into the mixing chamber during nebulization and exit the nebulizer outlet into the oral cavity of the patient.

18. The nebulizer according to claim 17, wherein each medicine receiver is shaped to match a shape uniquely associated with a different medicine.

19. The nebulizer according to claim 17, and further comprising air curtain conduits that are configured to supply a curtain of air above and below the nebulized medicine and gas to enhance penetration of nebulized medicine into the airway of the patient.
