ABSTRACT:
A flashback chamber for a catheter assembly including a main body portion having a cavity formed therein which is structured to include a path of fluid flow along its length defined by a plurality of sequentially disposed chambers separated, at least in part, by transversely located ribs. The path of fluid flow is at least partially defined by a plurality of ports formed at opposite ends of the spaced apart ribs. An air only permeable vent structure is located at the end of the path of fluid flow so as to properly vent air forced from the cavity as blood from the catheter assembly successively fills the sequentially disposed chambers.
