The priming attachment for a vacuum syringe can prevent air that is drawn out of the IV set and into the vacuum syringe from being released into the environment or back into the IV set. The priming attachment couples to the vacuum syringe and prevents the syringe plunger from reentering the syringe barrel. One embodiment of the priming attachment includes arms that fit inside the barrel and are pulled distally until they are released from the barrel. Once the arms released, the arms cannot reenter the barrel, which prevents distal movement of the plunger relative to the barrel. Another embodiment of the priming attachment includes a key that couples with a notch in a modified plunger. The modified plunger can rotate between a free position, where it can reciprocate within the barrel, and a locked position, where the notch aligns with the key and prevents translation of the modified plunger.
A priming attachment for a vacuum syringe, the priming attachment comprising (a) a proximal cap comprising one or more engagement features configured to couple to a plunger flange of the vacuum syringe and (b) stoppers extending distally from at least one of the one or more engagement features, wherein each stopper comprises:
A priming attachment for a vacuum syringe, the priming attachment comprising:
A priming system for a vacuum syringe, the priming system comprising:
