Abstract
The fitment is an elongated connector providing a conduit for aspirant to flow from a pump cartridge to an interior of the collection bag. The connector has a first end configured for attachment to the pump cartridge and a second end for positioning within the interior of the collection bag. The second end also includes at least one notch formed in the connector. The notch acts to prevent the collection bag from sealing off the conduit during surgery so that a sufficient amount of air will remain within the bag to allow a surgeon to air vent an aspiration path during surgery.
