Abstract
A simplified, user-friendly method and apparatus for producing and collecting a human breath sample, and particularly alveolar air, for analysis of the constituent components thereof. The invention includes an elongated, hollow container and a breath delivery device for directing a subject's breath into the container. A closure device is provided for accommodating the insertion of the breath delivery device into the container and for substantially sealing the container. The volume of the container is small in comparison to the normal human breath which has the effect of purging the container of the initial breath portion and leaving primarily only the alveolar air.
