Abstract: An air sampling device and method is described, the air sampling device having a bag, an interior of the bag, a conduit coupled with the interior of the bag, the conduit generally being a duck-bill valve within the interior of the bag.

Abstract: An air sampling device for obtaining an air sample from a person's lungs, and a method for using the same. The air sampling device is comprised of generally of a breath intake structure, an expandable bag structure, an adhesive patch, and a removable adhesive patch cover. Optionally an adhesive inlet seal patch also seals either the expandable bag inlet or an outer shell. The outer shell is provided to capture the air sample should the expandable bag structure fail. A person breathes into the breath intake, the device directing a first predetermined volume of breath into the expandable bag structure, and the remainder of breath also into the expandable bag, the remainder of the breath expelling the first predetermined volume of waste air from the expandable bag structure. The breath intake structure and removable adhesive patch cover are removed and the adhesive patch seals the interior surfaces of the expandable bag structure.

Abstract: An air sampling device for obtaining a sample of air from a person's lungs. The air sampling device is comprised of a blow tube connected to a waste air collection bag, and an air capture assembly connected to the blow tube by a needle assembly, for directing a portion of the air from the blow tube into the air sample capture assembly. The air sample capture assembly including a test tube containing a vacuum and having a rubber stopper that separates the vacuum contained within the test tube from the needle assembly connected to the blow tube. The rubber stopper is capable of being pierced by a needle of the needle assembly at a predetermined time. Additionally, the invention includes a method of using the air sampling device for obtaining a sample of air from a person's lungs.
