ABSTRACT:
A syringe device includes a syringe tube having a distal end with a passageway in fluid communication with a cavity thereof. A plunger rod slidingly and sealingly engages within the cavity of the syringe tube. The plunger rod includes at least one aperture in fluid communication with a hollow interior of the plunger rod. A plunger tip is engaged with a distal end of the plunger rod and interacts with an inner surface of the side wall of the syringe tube to separate the cavity into first and second areas. The at least one aperture fluidly connects the hollow interior of the plunger rod and the first area of the syringe tube cavity, such that the generally hollow plunger rod interior allows air to move between an outside of the syringe device and the first area of the cavity during sliding movement of the plunger rod within the syringe tube.
