摘要：
A blood gas syringe includes a porous plastic plug having a crosslinked hydrogel affixed to a wall of a passageway of the plug. When a blood sample is taken with the syringe, the incoming sample forces air in the system out through the passageway of the plug until the sample contacts the hydrogel, causing the passageway to seal shut.
