Abstract

A nebulizer is provided that includes an internal medication chamber and a pressurized gas diverter. The internal medication chamber is configured for holding a medication. The pressurized gas diverter includes a diverter orifice.

Claims (47)

1. A nebulizer comprising:

an internal medication chamber configured for holding a medication;

a pressurized gas diverter that includes a diverter orifice; and

a diverter override mechanism configured to actuate the pressurized gas diverter when engaged, the diverter override mechanism comprising a flexible button and a rotatable flange, the rotatable flange configured to restrict the button from actuating the pressurized gas diverter when rotated in a first direction, the rotatable flange configured to permit the button to actuate the pressurized gas diverter when rotated in a second direction.

2. The nebulizer of claim 1 , further comprising a visual indicator that mechanically moves in response to pressure fluctuations within the internal medication chamber.

3. The nebulizer of claim 1 , further comprising a gas outlet orifice in proximity of the diverter orifice, wherein a gas flow from the gas outlet orifice is substantially received through the diverter orifice when the pressurized gas diverter is deactuated and wherein the gas flow received through the diverter orifice is substantially less when the pressurized gas diverter is actuated.

4. The nebulizer of claim 1 , further comprising a diverter-actuator-deactuator that actuates the pressurized gas diverter by substantially sealing an opening of the diverter in response to inhalation and deactuates the diverter by unsealing the opening of the diverter in response to lack of inhalation.

5. The nebulizer of claim 4 , wherein the diverter-actuator-deactuator has a bowl shape that is made of a flexible material.

6. The nebulizer of claim 5 , wherein the diverter-actuator-deactuator stretches to substantially seal said opening of the pressurized gas diverter.

7. The nebulizer of claim 5 , wherein the diverter-actuator-deactuator has an original shape in response to the lack of breathing or exhalation.

8. The nebulizer of claim 4 , wherein the diverter-actuator-deactuator has a piston construction that substantially seals the opening of the pressurized gas diverter in response to the inhalation and unseals the opening in response to the lack of inhalation.

9. The nebulizer of claim 1 , wherein the pressurized gas diverter enables creation of a medical aerosol from the medication when actuated in response to inhalation.

10. The nebulizer of claim 9 , wherein the pressurized gas diverter reduces production of the medical aerosol when deactuated in response to a lack of breathing, exhalation, or reduced inhalation.

11. The nebulizer of claim 10 , wherein the pressurized gas diverter prevents production of the medical aerosol when deactuated.

12. A nebulizer, comprising:

a housing having an internal medication chamber configured for holding a medication that is capable of being converted into a medical aerosol;

a chamber air outlet coupled with the internal medication chamber for transferring the medical aerosol to a living being;

one or more liquid outlet orifices configured for permitting pressurized gas to mix with the medication;

a gas outlet orifice configured for permitting pressurized gas to shear across a surface of the one or more liquid outlet orifices, wherein the gas outlet orifice is adjacent to the one or more liquid outlet orifices;

a pressurized gas diverter containing a diverter orifice configured for preventing the pressurized gas from shearing across a surface of the one or more liquid outlet orifices when an opening in the pressurized gas diverter is not at least substantially sealed;

and a diverter override mechanism configured to actuate the pressurized gas diverter when engaged, the diverter override mechanism comprising a flexible button and a rotatable flange, the rotatable flange configured to restrict the button from actuating the pressurized gas diverter when rotated in a first direction, the rotatable flange configured to permit the button to actuate the pressurized gas diverter when rotated in a second direction.

13. The nebulizer of claim 12 , wherein an amount of flow through the diverter orifice responds to fluctuations of pressure within the internal medication chamber.

14. The nebulizer of claim 12 , wherein an amount of flow through the diverter orifice responds to an operator intervention.

15. The nebulizer of claim 12 , wherein pressure fluctuations within the internal medication chamber are visually indicated through mechanical movement of a visual indicator.

16. The nebulizer of claim 12 , wherein pressure within the internal medication chamber fluctuates in response to a living being's breathing through an outlet of the nebulizer.

17. A method of deactuating a nebulizer in response to breathing of a living being, the method comprising:

deactivating a diverter override mechanism, the diverter override mechanism configured to actuate a pressurized gas diverter when activated, the diverter override mechanism comprising a flexible button and a rotatable flange, the rotatable flange configured to deactivate the diverter override mechanism when rotated in a first direction;

receiving pressurized gas into the pressurized gas diverter at a diverter orifice of the pressurized gas diverter from a gas outlet orifice of a nozzle assembly;

when an opening at a top of the diverter is substantially sealed, wherein the opening at the top of the diverter is at an opposing end of the diverter from the diverter orifice,

creating aerosol by permitting pressurized gas that entered an internal medication chamber by shearing across one or more liquid outlet orifices to mix with medication located in the internal medication chamber; and

when the opening at the top of the diverter is not substantially sealed, reducing aerosol production by allowing the pressurized gas that entered the diverter to escape the diverter through the opening.

18. The method as recited by claim 17 , wherein the method further comprises:

adjusting, with an air inlet valve, an amount of flow through the diverter orifice in response to fluctuations of pressure within the internal medication chamber.

19. The method as recited by claim 17 , wherein the method further comprises:

adjusting, by activating the diverter override mechanism, an amount of flow through the diverter orifice in response to an operator intervention.

20. The method as recited by claim 17 , wherein the method further comprises:

providing a visual indication of pressure fluctuations within the internal medication chamber through mechanical movement located on the outside of the nebulizer.

21. The method as recited by claim 17 , wherein the method further comprises:

enabling, with an air inlet valve, fluctuation of pressure within the internal medication chamber in response to the living being breathing through an outlet of the nebulizer.

22. The method as recited by claim 17 , wherein:

the at least substantially sealing is in response to the breathing; and

the not sealing occurs when there is a lack of breathing.

23. The method of claim 22 , wherein the lack of breathing is selected from a group consisting of breathing has not been initiated and breathing has stopped.

24. A breath actuated nebulizer comprising:

an internal medication chamber configured for holding a medication that is capable of being converted into a medical aerosol;

a pressurized gas diverter that includes a diverter orifice, wherein the pressurized gas diverter enables creation of the medical aerosol when actuated in response to inhalation and reduces creation of the medical aerosol when deactuated in response to a lack of breathing or exhalation; and

a diverter override mechanism configured to actuate the pressurized gas diverter when engaged, the diverter override mechanism comprising a flexible button and a rotatable flange, the rotatable flange configured to restrict the button from actuating the pressurized gas diverter when rotated in a first direction, the rotatable flange configured to permit the button to actuate the pressurized gas diverter when rotated in a second direction.
