Abstract

Provided is a priming mechanism for priming a biofluid drop ejection device having a drop ejection opening leading to an ejection reservoir. The priming mechanism includes a vacuum unit which generates a vacuum force, connected to a vacuum nozzle. The vacuum nozzle is located over the drop ejection opening. A disposable sleeve or tubing is attached to the vacuum nozzle and is placed in operational contact with the drop ejection opening. A fluid height detection sensor is positioned to sense a fluid height within at least one of the disposable tubing and the vacuum nozzle. Upon sensing a predetermined fluid height, by the fluid height detection sensor, the priming operation is completed, and the primer mechanism is removed from the operational contact with the drop ejection opening.
