Breath actuated nebulizer having a pressurized gas diverter with a diverter orifice
View Patent ↗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.
1. A nebulizer comprising:
an internal medication chamber configured for holding a medication;
a pressurized gas diverter comprising a top, a bottom, a wall encompassing an inner chamber, a diverter orifice located at the bottom of the pressurized gas diverter, a diverter opening opposite the diverter orifice and located at the top of the pressurized gas diverter; and
a diverter-actuator-deactuator that actuates the pressurized gas diverter by substantially sealing the diverter opening, and deactuates the pressurized gas diverter by unsealing the diverter opening, wherein the opening is configured to divert a pressurized gas from shearing across a surface of a liquid outlet orifice when the diverter opening is at least partially unsealed.
2. The nebulizer of claim 1 , further comprising a diverter override mechanism configured to permit creation of medical aerosol when engaged.
3. The nebulizer of claim 1 , further comprising a visual indicator that mechanically moves in response to pressure fluctuations within the internal medication chamber.
4. 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.
5. The nebulizer of claim 1 , wherein the diverter-actuator-deactuator actuates the pressurized gas diverter in response to inhalation and deactuates the pressurized gas diverter in response to lack of inhalation.
6. The nebulizer of claim 1 , wherein the diverter-actuator-deactuator comprises a flexible material in a bowl shape.
7. The nebulizer of claim 1 , wherein the diverter-actuator-deactuator stretches to substantially seal said diverter opening.
8. The nebulizer of claim 5 , wherein the diverter-actuator-deactuator has an original shape in response to the lack of inhalation.
9. The nebulizer of claim 5 , wherein the diverter-actuator-deactuator has a piston construction that substantially seals the diverter opening in response to the inhalation and unseals the diverter opening in response to the lack of inhalation.
10. 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.
11. The nebulizer of claim 10 , wherein the pressurized gas diverter reduces production of the medical aerosol when deactuated in response to a lack of breathing, exhalation, or reduced inhalation.
12. The nebulizer of claim 11 , wherein the pressurized gas diverter prevents production of the medical aerosol when responsively deactuated.
13. A nebulizer, comprising:
a housing having an internal medication chamber;
a chamber air outlet coupled with the internal medication chamber;
a liquid outlet orifice configured to permit a pressurized gas to mix with a medication;
a gas outlet orifice adjacent the liquid outlet orifice and configured to permit the pressurized gas to shear across a surface of the liquid outlet orifice; and
a pressurized gas diverter comprising a top, a bottom, a wall encompassing an inner chamber, a diverter orifice located at the bottom of the pressurized gas diverter, a diverter opening opposite the diverter orifice and located at the top of the pressurized gas diverter;
a diverter-actuator-deactuator that actuates the pressurized gas diverter by substantially sealing the diverter opening, and deactuates the pressurized gas diverter by unsealing the diverter opening, wherein the opening is configured to divert the pressurized gas from shearing across the surface of the liquid outlet orifice when the diverter opening is at least partially unsealed;
wherein a gap between the gas outlet orifice and the diverter orifice remains substantially same when the pressurized gas shears across the surface of the liquid outlet orifice.
14. The nebulizer of claim 13 , wherein an amount of flow through the diverter orifice responds to fluctuations of pressure within the internal medication chamber.
15. The nebulizer of claim 13 , wherein an amount of flow through the diverter orifice responds to an operator intervention.
16. The nebulizer of claim 13 , wherein pressure fluctuations within the internal medication chamber are visually indicated through mechanical movement of a visual indicator.
17. The nebulizer of claim 13 , wherein pressure within the internal medication chamber fluctuates in response to a living being's breathing through an outlet of the nebulizer.
18. A nebulizer, comprising:
a housing having an internal medication chamber;
a chamber air outlet coupled with the internal medication chamber;
a liquid outlet orifice configured to permit a pressurized gas to mix with a medication;
a gas outlet orifice adjacent the liquid outlet orifice and configured to permit the pressurized gas to shear across a surface of the liquid outlet orifice;
a pressurized gas diverter comprising a top, a bottom, a wall encompassing an inner chamber, a diverter orifice located at the bottom of the pressurized gas diverter, a diverter opening opposite the diverter orifice and located at the top of the pressurized gas diverter;
a diverter-actuator-deactuator that actuates the pressurized gas diverter by substantially sealing the diverter opening, and deactuates the pressurized gas diverter by unsealing the diverter opening, wherein the opening is configured to divert the pressurized gas from shearing across the surface of the liquid outlet orifice when the diverter opening is at least partially unsealed; and
a pressurized gas diverter override mechanism configured to permit creation of medical aerosol when engaged;
wherein a gap between the gas outlet orifice and the diverter orifice remains substantially same when the pressurized gas shears across the surface of the liquid outlet orifice.
19. The nebulizer of claim 18 , further comprising a wherein the diverter-actuator-deactuator is configured to actuate the pressurized gas diverter in response to inhalation and deactuate the pressurized gas diverter in response to lack of inhalation.
20. The nebulizer of claim 18 , wherein the diverter-actuator-deactuator comprises a flexible material in a bowl shape.
