DISPOSABLE, IN-LINE ENTEROTOMY DETECTION DEVICE

摘要

An in-line enterotomy detection device for use in a surgical procedure wherein access to an internal operating field is provided through a plurality of access ports and further wherein a pressurized insufflating gas is delivered to the internal operating field through one access port and vented from the internal operating field through another access port, the in-line enterotomy detection device comprising: a housing having an inlet, an outlet, and a passageway connecting the inlet to the outlet, the inlet being configured for connection to an access port venting gas from the internal operating field and the outlet being configured to vent gas from the in-line enterotomy detection device; and at least one non-electrical colorimetric enteric gas sensor disposed within the passageway for determining at least one of the presence of a selected enteric gas and the concentration of a selected enteric gas and indicating that presence by a visually-apparent change in appearance.
