Abstract
A gas mixture apparatus includes a measurement control system, an activation system, a pressurized chamber with one or more gases, and a mixing chamber. The apparatus can also include additional pressure regulation control systems. The gas mixture apparatus can be used to introduce and automatically perform the steps to achieve a desired concentration of the one or more gases contained in the pressurized chamber. The gas mixture apparatus can include the pressurized chamber within the apparatus itself such that no external devices are necessary for introducing the one or more gases into the mixing chamber.
Claims16
A hand-held gaseous injector assembly, comprising:
- a syringe body with an outlet;
- a plunger slidably disposed in the syringe body and with the syringe body, defining a first chamber within the syringe body;
- a second chamber disposed within at least one of the syringe body and the plunger, the second chamber comprising a seal and an internal volume containing at least a first fluid in a concentration different than that in atmospheric air and at a pressure greater than that of the surrounding atmospheric air;
- a metering device configured to limit at least one of a volume and a pressure of at least the first chamber when at least the first fluid is introduced into the first chamber;
- a filling mechanism comprising a channel and an aperture between the second chamber and the first chamber, the filling mechanism configured to direct the first fluid from the second chamber into the first chamber of the syringe body so as to move the plunger and expand the first chamber;
- and
- a pressure regulation system comprising:
- a first pressure regulation system configured to regulate the first fluid within the second chamber, wherein the first pressure regulation system releases the first fluid out of the second chamber when pressure within the second chamber exceeds a threshold value, and
- a second pressure regulation system configured to regulate at least the first fluid within the first chamber.
