  • Publication number: 20120330176
    Abstract: A device to facilitate carbon dioxide sampling in the exhalation breath of a person comprising a single nasal prong (10) insertable into a nostril of the person having a first lumen (20) which allows gas passage from the nostril to the surrounding external air, a second lumen (34) located within the first lumen (20). A tube (40) is connected at a first end (42) to an end of the second lumen (34) that is further from the nostril and connectable at a second end (44) to a carbon dioxide monitoring device (50). The carbon dioxide monitoring device (50) detects the level of carbon dioxide in the portion of the person's exhalation that passes through the second lumen (34). The portion of the person's exhalation that passes through the first lumen (20) is dispersed in the surrounding air.

This coagulant hardens and encompasses the sharps. This process can be repeated at intervals until the container is full. The lid is then closed and the container ready for disposal in a landfill or some other appropriate location.
