Conduit access adaptor devices and methods

An adaptor device configured to establish a fluid connection through an access point opening into a conduit section interior of a conduit section of a conduit, the access point opening extending through a sidewall thickness of a conduit section sidewall of the conduit section, the adaptor device comprising:

• an adaptor conduit structure at least partially defining a base conduit extending from an adaptor inlet;
• a conduit connector, the conduit connector configured to engage at least a portion of the conduit section to couple the adaptor conduit structure to the conduit section such that the adaptor inlet of the adaptor conduit structure is external to the conduit;
• and
• an elbow nozzle at least partially defining an elbow conduit extending to an adaptor outlet, the elbow nozzle configured to couple with the adaptor conduit structure such that the elbow conduit and the base conduit at least partially collectively define an adaptor conduit extending between the adaptor inlet and the adaptor outlet through both the adaptor conduit structure and the elbow nozzle, the elbow nozzle configured to at least partially extend through the access point opening into the conduit section interior such that the adaptor outlet is within the conduit section interior and a central axis of the adaptor outlet extends at least partially parallel to a longitudinal axis of the conduit section within the conduit section interior,
• wherein the adaptor device is configured to direct a fluid to flow through the adaptor conduit and through the adaptor outlet as a fluid stream directed in a particular flow direction in the conduit section interior, the particular flow direction at least partially parallel to the longitudinal axis of the conduit section within the conduit section interior.
