Abstract: An improved apparatus, method and system are provided for medical liquid administration, including in particular liquid medication and/or flush solution infusions. The inventive apparatus includes a barrel, a plunger slidably disposed within the barrel and extending from a distal end thereof, and at least one medical liquid delivery line having a proximal end fixedly positioned relative to the barrel, wherein the medical delivery line is fluidly interconnectable proximal to the plunger and extends along at least a portion of the barrel and in a direction distally away from the distal end thereof. To accommodate the administration of both a liquid medication and flush solution, two coincidentally-positioned medical liquid delivery lines may be included, each of which may extend through the plunger to the valve. The valve may be positionable to accommodate the selective administration of a desired medical liquid through an interconnected catheter interconnection line.
