Embodiment Construction

[0095] Described herein are devices and methods for creating a registry of respiratory gas samples and analyzing the gases in that registry for desired monitoring, screening, or diagnostic purposes. In the illustrated embodiment, for exemplary purposes, a sample of the patient's breath is shown drawn from the patient into the instrument by application of a vacuum. However, the present invention also applies the patient's breath to the instrument in order to allow the instrument to collect breath samples without the need for vacuum application.

[0096] In some variations, one or more breath parameters are measured to identify different components of the breath and corresponding time periods, and a pneumatic system is used for capturing the portion of exhaled breath in the sample tube using the identified time periods. In some variations, one or more valves and / or flow control mechanisms (such as vacuum pumps, for example) are used to regulate the flow rate of gas drawn into th...

Abstract

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.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of U.S. Provisional Application No. 61 / 763,896, filed February 12, 2013, and U.S. Provisional Application No. 61 / 794,254, filed March 15, 2013, respectively, the disclosure of which applications Incorporated herein by reference in its entirety. technical field [0003] Described herein are devices and methods for analyzing exhaled breath for diagnostic purposes. More particularly, devices and methods are described for sampling and analyzing relevant portions of the breathing cycle (eg, end-tidal gas) from a person's breath. The devices and methods can be used, for example, to correlate gas analysis with underlying physiological conditions for diagnostic, monitoring, or screening purposes, or in conjunction with therapeutic treatment. Background technique [0004] Secretion of specific metabolites and chemicals produced in or into the body and bloodstream in the breath. Levels in ...
