Abstract
Breath analysis systems and methods test for infectious diseases in exhaled breath gas or condensate. An automatic breath sampling system can obtain reliable samples over a variety of clinical situations. In some variations, the system is modular system and can protect the equipment and clinician from contamination. In some variations, the system can be a point-of-care rapid-result instrument. In some variations, can be configured for off-line analysis in which case the collected sample is presented to a stand-alone analyzer for measurement.
Claims23
A breath analysis apparatus comprising:
- an inlet to obtain a flow of gas from a subject;
- a breath detector to measure a breathing signal in the flow of gas;
- a processor that determines an acceptable breath based on the breathing signal;
- a modular subassembly containing the pathway for the flow of gas that is removable from the apparatus;
- valves for controlling the flow of gas within the pathway, wherein the valves are fluidly disconnected from the flow of gas;
- and
- an analyte composition sensor fluidly connected to the flow of gas.
A method for screening for infectious disease, comprising:
- obtaining a breath sample from a subject, wherein the breath sample passes through a pathway in an instrument;
- analyzing, using a breath analyzer in the instrument, the breath sample for a presence and level of an analyte that correlates to the disease;
- determining the presence of the disease;
- removing the pathway from the instrument;
- and
- inserting a replacement pathway into the instrument.
