Abstract
A filling system for syringes utilizing short needles to be filled from a vial having a thick septum is described. The system may be useful in any situation where the septum or vial stopper of a medication container is thicker than the usable length of the needle on the delivery device. Preferably, the syringe is filled just prior to use. The short needle includes an optional limiter which only permits a certain predetermined length of the needle cannula to protrude beyond the limiter a distance which limits penetration of the needle tip into both the skin and a vial stopper. The system and adapter may be useful for needles having a protrusion distance from approximately 0.5 mm to 3 mm, or any needle with a protrusion length shorter that the thickness of a septum to be accessed. Furthermore, a device is provided with shielding capabilities to shield the needle of the device.
