  • Patent number: 4677987
    Abstract: A connector and sampling line for obtaining sample gases from a patient's exhaled gas stream present in an air tube coupled to the patient is disclosed. The sampling line comprises a sampling end portion having an open end and at least one hole in a wall of the end portion. A tubular shaped connector through which the gas stream passes along a first path includes a hollow cylinder coupled to the wall of the connector and protruding therefrom.
