Abstract
A housing and method of using the same is configured and coupled to an aerosol generator which delivers aerosol into an oxygen stream transporting both to a patient via a nasal cannula, in a way to minimize condensation at low liters per minute flow rate.
Claims17
A device for delivery of aerosol along with supplemental oxygen from an oxygen supply to a nasal cannula of a patient, the device comprising:
- a) a housing, wherein the housing includes a base and a cylindrical wall, wherein the base and the cylindrical wall define a chamber through which supplemental oxygen is configured to be led, and
- b) two couplers, wherein a first of the two couplers is an inlet for supplemental oxygen supply into the chamber, wherein a second of the two couplers is an outlet for delivery of the supplemental oxygen supply containing an aerosol, wherein each of the two couplers is configured to engage a nasal cannula line,
- wherein the cylindrical wall is configured to snugly fit to an aerosol delivery portion of a nebulizer, wherein the aerosol delivery portion of the nebulizer is not positioned to act as a baffle to air flow between the two couplers, wherein there is no baffle or impediment to air flow and aerosol through the device,
- wherein the housing and couplers are designed to facilitate laminar flow, wherein each of the two couplers also defines a void which is shaped as an end of an ellipsoid, and wherein the void extends outward and perpendicular from the cylindrical wall.
1 more element
A non-transitory computer readable medium comprising storing computer readable instructions, configured to be acted upon by a 3D printer configured to cause the 3D printer to print an adaptor comprising:
- a) a housing, wherein the housing includes a base and a cylindrical wall, wherein the base and the cylindrical wall define a chamber through which supplemental oxygen is led, and
- b) two couplers, wherein a first of the two couplers is an inlet for supplemental oxygen supply into the chamber, wherein a second of the two couplers is an outlet for delivery of the supplemental oxygen supply containing an aerosol, wherein each of the two couplers is configured to engage a nasal cannula line,
- wherein the cylindrical wall is configured to snugly fit to an aerosol delivery portion of a nebulizer, wherein the aerosol delivery portion of the nebulizer is not positioned to act as a baffle to air flow between the two couplers, wherein there is no baffle or impediment to air flow and aerosol through the adaptor,
- wherein the housing and the couplers are designed to facilitate laminar flow, wherein the non-transitory computer readable medium is configured to cause the 3D printer to print an adaptor wherein a void starts in a slightly larger cylindrical portion and terminates in the chamber, wherein the void is shaped as an end of an ellipsoid and the void extends outward and perpendicular from the cylindrical wall.
1 more element
A method for producing an adaptor for delivery of aerosol along with supplemental oxygen from an oxygen supply to a nasal cannula of a patient, the method comprising:
- causing an additive printing device to print the adaptor according to a prescribed printing process having prescribed parameters;
- the adaptor comprising:
- a housing, wherein the housing includes a base and a cylindrical wall, wherein the base and the cylindrical wall define a chamber through which supplemental oxygen is configured to be led, and
- two couplers, wherein a first of the two couplers is an inlet for supplemental oxygen supply into the chamber, wherein a second of the two couplers is an outlet for delivery of the supplemental oxygen supply containing an aerosol, wherein each of the two couplers is configured to engage a nasal cannula line,
- wherein the cylindrical wall is configured to snugly fit to an aerosol delivery portion of a nebulizer, wherein the aerosol delivery portion of wherein the aerosol delivery portion of the nebulizer is not positioned is not positioned to act as a baffle to air flow between the two couplers, wherein there is no baffle or impediment to air flow and aerosol through the adaptor,
- wherein the housing and couplers are designed to facilitate laminar flow,
- the housing, base, cylindrical wall, and couplers are integrally formed, and wherein each of the two couplers defines a void which is shaped as an end of an ellipsoid and the void extends outward and perpendicular from the cylindrical wall.
