Abstract
A plug (36, 76) can be used to block the flashback chamber (34) or the proximal end of the adapter in an intravenous catheter assembly (10). The plug can provide ventilation to the flashback chamber or the adapter. The plug may include a body (38) and a neck portion (44) extending from the body. The neck portion may include one or more ventilation channels (54, 78) that can be aligned with the longitudinal axis of the plug. The neck portion may include one or more transverse channels (80) that can provide ventilation and / or blood collection in the event of blood leakage into the plug.
