Abstract
The present invention involves a fill needle system for aseptically dispensing a pharmaceutical fluid in an aseptic chamber comprises a fill needle tubing in fluid communication with a pharmaceutical fluid source via flexible tubing and extending through a fill needle hub; a fill needle dispensing tip disposed at a dispensing end of the fill needle tubing; a fill needle sheath shaped and arranged to removably mate with and seal aseptically to the fill needle hub to form an aseptically sealed volume enclosing the dispensing tip; and a fluid pressure pulse induction system disposed and configured to compress the flexible tubing in order to dislodge droplets of pharmaceutical fluid retained on the dispensing tip after halting dispensing of the pharmaceutical fluid. An associated method of dispensing pharmaceutical fluid comprises operating the fluid pressure pulse induction system to dislodge the droplets. The system may comprise a controller for automatically controlling the dispensing and droplet dislodging.
