PRIMING APPARATUS FOR A DRIP CHAMBER OF A FLUID INFUSION SYSTEM

Apparatuses for priming a drip chamber of an infusion tube seta are described. A priming apparatus may be incorporated into a cavity of a body, such as a drip chamber cap, that is attached to or integrally formed with the inlet side of drip chamber. The priming apparatus includes a closure mechanism at least a portion of which is accommodated in a cavity in the body. The cavity is part of an outflow or vent passage through the body (e.g., the drip chamber cap) and the closure mechanism is operable, e.g., responsive to user force, to selectively open the outflow passage, thereby unsealing the vent cavity to ambient air and allowing air to be purged from the fluid system during priming of the drip chamber. When the closure mechanism is an closed position, the outflow passage and vent cavity as sealed from ambient air, preventing any air from passing into the fluid system through the cap.
