Abstract
An arterial blood sampling syringe consisting of a barrel and a plunger assembly in which the plunger is hollow and provided at its distal end with two annular rings which cooperate with the hollow plunger and each other to maintain a sealing ring and gas-pervious but liquid impervious membrane in position at the end of the plunger. The plunger position in the barrel may be preset to receive any desired blood sample volume. Further blood flow is halted when the barrel of the syringe fills to the volume desired.
