Self-purging, air-stabilizing, illuminated collection system for breath analysis
First Claim
1. A breath analysis system, comprising:
- a breath collection tube having at least a first end into which breath is exhaled by a user without lip or mouth contact with the first end and a second end from which air is exhausted to self-purge the system, the breath collection tube for stabilizing the flow of exhaled breath; and
a sensing device comprising;
a sensor airway; and
at least one sensor.

Abstract
A breath analysis system includes a dual-entry, illuminated breath collection tube that allows purging of ambient air while stabilizing the pressure and/or turbulence of exhaled breath. Circular illumination at either end of the collection tube acts as a visual prompt for proper use and for the reporting of test results. The collection tube may be placed along the width or length of a hand piece without adding size or bulk to the hand piece. The form factor utilization feature of the collection tube is suitable for adding breath alcohol measurement or other breath measurement capability to handheld products such as cell phones, PDAs, iPods®, MP3 players, GPS units, cigarette lighters, and police batons.

22. A method for performing breath analysis, comprising the steps of:
-
providing a breath collection tube having at least a first end and a second end;
a sensor for measuring a characteristic of exhaled breath;
exhaling breath into the first end of the breath collection tube without lip or mouth contact with the first end;
