摘要： A biological fluid separation device adapted to receive a biological fluid sample having a first portion and a second portion is disclosed. The device includes a housing having a first chamber having a first chamber inlet for receiving the biological fluid sample therein and a first chamber outlet. The housing has a second chamber having a second chamber inlet and a second chamber outlet, and a separation member separating at least a portion of the first chamber outlet and the second chamber. The separation member is adapted to restrain the first portion of the biological fluid sample within the first chamber and to allow at least a portion of the second portion of the biological fluid sample to pass into the second chamber. An actuator, such as a vacuum source, draws the biological fluid sample into the first chamber and the second portion into the second chamber.

摘要： A plug may be used to plug a proximal end of a flashback chamber or an adapter in an intravenous catheter assembly. The plug may provide air venting of the flashback chamber or the adapter. The plug may include a body and a neck portion extending from the body. The neck portion may include one or more air vent channels, which may be aligned with a longitudinal axis of the plug. The neck portion may include one or more transverse channels, which may provide air venting and/or blood collection in case of leakage of blood into the plug.
