Abstract
A blood-gas sampler in the nature of a syringe comprising a hollow internally stepped cylindrical barrel and a coaxial stepped plunger having one or more nesting stepped seals at the leading end thereof, the assembly accommodating arterial blood aspiration causing retraction of the plunger within the barrel and discharge of blood from the hollow of the barrel caused by advancement of the plunger. A clip prevents inadvertent excessive retraction of the plunger during the blood aspiration and blood discharge phases.
