Abstract
An inhalation device which entrains air to modify a source gas, such as pure oxygen, down to different selected levels of lower gas concentrations, with a high total gas flow being achieved for inhalation. The inhalation device allows eating and suctioning without interference while maintaining a constant uninterrupted gas supply at high volumes. The inhalation device is adapted for disposal adjacent to the nose and mouth of a person, and includes a nose hood connected to a chamber. The chamber has a central portion defining a longitudinal axis orientated perpendicular to the nose hood and also defining an opening aligned with and facing the nose in a configuration such that gas is inhalable from the central portion to the nose without the gas directly impacting the breathing orifices of a patient wearing the device.
Claims30
An inhalation device, comprising:
- a nose hood having an opening, the nose hood defining a cavity and a vertical axis;
- a chamber connected with the nose hood and including a first end portion, a second end portion, and a central portion, the central portion defining a longitudinal axis being oriented substantially perpendicular to the vertical axis, the first end portion and the second end portion being coaxially disposed about the longitudinal axis, wherein the first end portion extends to a first end of a chamber and the second end portion extends to a second end of the chamber, the first end and the second end each being angularly offset from the longitudinal axis;
- and
- a mixing section connected with either of the first end or the second end, and at least one fluid, wherein the mixing section delivers the at least one fluid to the first end in a fluid flow path configured to travel in a direction along the longitudinal axis and exit the chamber from the second end;
- wherein the central portion defines at least one opening disposed in flush alignment with an upper wall of the central portion in a configuration such that the at least one fluid of the fluid flow path is inhalable from the central portion into the nose hood.
An inhalation device, comprising:
- a nose hood defining a cavity;
- a chamber connected with the nose hood having a central portion, the central portion defining a longitudinal axis, said chamber configured to receive incoming gas flow post air entrainment at an angle of between about 0 and about 70 degrees with respect to the longitudinal axis, said chamber being oriented substantially perpendicular to the nose hood;
- and
- a mixing section being connected with the chamber and at least one fluid, wherein the mixing section delivers the at least one fluid to a first end portion of the chamber in a fluid flow path configured to travel in a direction along the longitudinal axis of the central portion and exit the chamber from a second end portion thereof, the first end portion and the second end portion being coaxially disposed about the longitudinal axis of the chamber;
- wherein
- the central portion defines at least one opening such that the at least one fluid of the fluid flow path is inhalable from the central portion into the nose hood;
- the first end portion of the chamber and the second end portion of the chamber are configured so as to be interchangeable with one other;
- and
- the second end portion includes a second end, which is angularly offset from the longitudinal axis of the central portion.
An inhalation device, comprising:
- a nose hood defining a cavity;
- a chamber connected with the nose hood and including a central portion being disposed below the nose hood, the central portion defining a longitudinal axis, said chamber configured to receive incoming gas generating a total gas flow post air entrainment at an angle of between about 35 and about 70 degrees with respect to the longitudinal axis, said chamber being oriented substantially perpendicular to the nose hood;
- and
- a mixing section connected with the chamber and at least one fluid, wherein the mixing section delivers the at least one fluid to a first end portion of the chamber in a fluid flow path configured to travel in a direction along the longitudinal axis of the central portion and exit the chamber from a second end portion thereof, the first end portion and the second end portion being coaxially disposed about the longitudinal axis of the chamber;
- wherein the central portion defines at least one opening such that the at least one fluid of the fluid flow path is inhalable from the central portion into the nose hood;
- and
- wherein the second end portion includes a second end, which is angularly offset from the longitudinal axis of the central portion.
