Filling system and method for syringes with short needles

A method of transferring a medical substance from a medication container having a septum with a thickness greater than 3 mm into a delivery device having a reservoir in fluid communication to a needle cannula attached to said delivery device having a forward tip extending away from said delivery device a usable length less than 3 mm;

• comprising the steps of:
• providing an adapter including a septum access needle having a lumen, in fluid communication with a distal portion of an adapter septum having a thickness less than the usable length of said needle cannula;
• penetrating said medication container septum with said septum access needle, wherein when said container septum is penetrated with said septum access needle fluid communication between said medical substance and said lumen occurs;
• penetrating said adapter septum with said delivery device needle, wherein when said adapter septum is penetrated with said delivery device needle, fluid communication between said medical substance and said lumen occurs, whereby, fluid communication between said substance in said container and said reservoir of said delivery device is established;
• and,
• aspirating said medical substance into said delivery device.

A method of transferring a medical substance from a medication container having a septum with a pre-determined thickness into a delivery device having a reservoir in fluid communication to a needle cannula attached to said delivery device having a forward tip extending away from said delivery device a pre-selected usable length;

• wherein said usable length is less than said pre-determined thickness of said container septum comprising the steps of:
• providing an adapter including a septum access needle having a lumen, in fluid communication with a distal portion of an adapter septum having a thickness less than the usable length of said needle cannula;
• penetrating said medication container septum with said septum access needle, wherein when said container septum is penetrated with said septum access needle fluid communication between said medical substance and said lumen occurs;
• penetrating said adapter septum with said delivery device needle, wherein when said adapter septum is penetrated with said delivery device needle, fluid communication between said medical substance and said lumen occurs, whereby, fluid communication between said substance in said container and said reservoir of said delivery device is established;
• aspirating said medical substance into said delivery device;
• shielding said delivery device needle with a needle shield, thereby concealing said forward tip of said needle cannula, wherein said shield is slidably engaged to said delivery device;
• performing an injection with said delivery device, locking said shield of said delivery device needle in a distal position after performing said injection step;
• providing said delivery device with said shield in an initial distal position concealing said forward tip of said needle cannula, wherein said forward tip is engageable to said adapter septum;
• and
• moving said shield to a proximal position exposing said usable length of said needle cannula.
