Sampling and storage registry device for breath gas analysis
Methods and systems are described to obtain and analyze one or more gas samples from the breath of a person, and organizing the samples in a sample registry for subsequent analysis. This technique solves the various problems that are associated with targeting an individual breath for analysis, and allows for additional versatility and options in the analysis process.
1. A breath sampling apparatus comprising:
a sensor that identifies the beginning and end of a breath, thereby dividing the breath pattern into different breath portions identifying the beginning and end of different breath portions;
a sample tube comprising a capillary channel in which the different breath portions occupy sections of volume of the capillary channel, wherein the sections have at least one end, and wherein the at least one end of adjacent sections are directly coupled to each other by contacting an end of another adjacent section;
a vacuum pump that draws a gas sample from a person's breath into the sample tube, the sample tube comprising gas from at least one breath and at least one breath portion; and
a computer to identify the location of gas in the sample tube corresponding to the beginning and end of the breath, and corresponding to the beginning and end of the breath portion.
2. The breath sampling apparatus of claim 1 , further comprising an analyzer that analyzes the different breath portions for a first parameter.
3. The breath sampling apparatus of claim 1 , wherein the different breath portions are from a single breath.
4. The breath sampling apparatus of claim 1 , wherein the different breath portions are from different breaths.
5. The breath sampling apparatus of claim 2 , wherein the analyzer analyzes the different breath portions for a second parameter.
6. The breath sampling apparatus of claim 1 , wherein the computer comprises a processor that identifies a desired breath portion from the different breath portions by receiving measurements of a breathing pattern characteristic, and wherein the sample tube receives gas from the desired breath portion.
