Abstract
This document provides systems, devices, and methods for treating hypocapnia. For example, systems, devices, and methods for delivering carbon dioxide (CO2) to a user are provided.
Claims23
A system for delivering carbon dioxide (CO2) to a user, the system comprising:
- a fluid receptacle defining an interior space to contain a fluid;
- and
- a cap device configured to be coupled to the fluid receptacle, the cap device comprising:
- an inner shell;
- an outer shell that is rotatably coupled about the inner shell;
- a mouthpiece positioned on the outer shell;
- a vent extending through the outer shell;
- a first opening extending through the inner shell;
- and
- a second opening extending through the inner shell.
7-23. (canceled)
A cap device configured to be coupled to a fluid receptacle for delivering carbon dioxide (CO2) to a user, the cap device comprising:
- an inner shell;
- an outer shell that is rotatably coupled about the inner shell;
- a mouthpiece positioned on the outer shell;
- a vent extending through the outer shell;
- a first opening extending through the inner shell;
- and
- a second opening extending through the inner shell.
30-34. (canceled)
A method of delivering carbon dioxide (CO2) to a user, the method comprising:
- attaching a cap device to a fluid receptacle defining an interior space to contain a fluid, the cap device comprising a mouthpiece;
- placing the cap device in an open position, wherein the mouthpiece is in fluid communication with the interior space of the fluid receptacle when the cap device is coupled to the fluid receptacle and in the open position;
- and
- breathing into and out of the fluid receptacle through the mouthpiece of the cap device.
39-45. (canceled)
A method of delivering carbon dioxide (CO2) to a user, the method comprising:
- placing a dry carbon dioxide saturated composition that releases CO2 when heated within a receptacle defining an interior space;
- heating the dry carbon dioxide saturated composition inside the receptacle using a heating system at least partially disposed within the interior space to a threshold temperature to generate CO2;
- and
- breathing into and out of the receptacle through a mouthpiece fluidly coupled to the interior space.
