Abstract

The subject invention is directed to a breath analyzer which is capable of detecting toxic gas levels from breath analysis. The subject invention includes a mouthpiece which is in communication with a plurality of discrete chambers, such as first and second discrete chambers, each being provided with a separate probe for breath analysis. The probes are connected to analyzers for determining detected levels of gas. In a first embodiment, a first probe may be provided for carbon monoxide detection with a second probe being provided for hydrogen cyanide detection. Advantageously, with this arrangement, breath analysis may be conducted on-site, for example at the site of a fire, to quickly and simultaneously determine carbon monoxide and hydrogen cyanide levels in a person'"'"'s blood stream. In a second embodiment, a first probe may be provided for detection of carbon monoxide and a second probe may be provided for detection of hydrogen. With this arrangement, a calibrated correction of measured carbon monoxide data can be made to correct for improperly detected hydrogen. As such, a highly accurate on-site measurement for carbon monoxide can be achieved.

Claims

1. An analyzer for detecting gas levels, said analyzer comprising:

a carbon monoxide probe for detecting carbon monoxide levels;

a hydrogen probe for detecting hydrogen levels; and

means for adjusting said detected carbon monoxide levels in view of said detected hydrogen levels.

2. An analyzer as in claim 1, further comprising a timer, wherein said timer is configured to indicate predetermined intervals of time for detecting carbon monoxide levels and hydrogen levels.

3. An analyzer as in claim 1, wherein said carbon monoxide probe is able to detect less than 30 parts per million of carbon monoxide.

4. An analyzer as in claim 1, further comprising means for generating a warning signal upon a predetermined level of carbon monoxide being detected.

5. An analyzer for detecting gas levels, said analyzer comprising:

a carbon monoxide probe for detecting carbon monoxide levels; and

,

a hydrogen cyanide probe for detecting hydrogen cyanide levels.

6. An analyzer as in claim 5, further comprising a timer, wherein said timer is configured to indicate predetermined intervals of time for detecting carbon monoxide levels and hydrogen cyanide levels.

7. An analyzer as in claim 5, wherein said carbon monoxide probe is able to detect less than 30 parts per million of carbon monoxide.

8. An analyzer as in claim 5, wherein said hydrogen cyanide probe is able to detect less than 200 parts per billion of hydrogen cyanide.

9. An analyzer as in claim 5, further comprising means for generating a warning signal upon a predetermined level of carbon monoxide being detected.

10. An analyzer as in claim 5, further comprising means for generating a warning signal upon a predetermined level of hydrogen cyanide being detected.
