ABSTRACT:
Improved disposable syringe for taking blood or other fluid samples, particularly arterial samples for blood gas testing or the like, which comprises a syringe body, a piston or plunger having a compressible end piece which forms a seal with the inner surface of the syringe body, the syringe body having a non-tapered section through which the end piece moves during withdrawal of the piston and preferably means for resisting further movement of the end piece when the desired sample size has been obtained. Also preferably the syringe has means which prevent contact between the compressible end piece and the end wall of the syringe.
