Syringe Assembly with Inverse Delivery

A syringe assembly having a reduced profile prior to use, comprising:

• a syringe barrel having an inside surface defining a chamber, an open proximal end, and a distal end having an opening therethrough;
• a plunger assembly disposed at least partially within the syringe barrel, the plunger assembly comprising an elongate plunger rod and a plunger head disposed on the plunger rod and slidably disposed within the syringe barrel, the plunger head separating the chamber of the syringe barrel into a proximal chamber adjacent the proximal end and a distal chamber adjacent the distal end;
• and
• a conduit extending across the plunger head between the proximal chamber and the opening at the distal end of the syringe barrel, wherein the conduit is radially centered with respect to a general elongated axis of the syringe barrel,
• wherein the syringe assembly is adapted to contain a fluid in the proximal chamber,
• wherein the fluid contained within the proximal chamber is adapted to be expelled through the conduit and out of the opening at the distal end of the syringe barrel upon movement of the plunger head toward the proximal end of the syringe barrel, and
• wherein movement of the plunger head toward the proximal end of the syringe barrel occurs based on conventional operation of expelling fluid from a conventional syringe with a squeezing movement between a thumb and forefinger.

A syringe assembly having a reduced profile prior to use, comprising:

• a syringe barrel having an inside surface defining a chamber, a first end, and a second end having an opening therethrough;
• an opening located at the first end, the opening being offset from a central axis of the syringe assembly;
• a vent located adjacent the second end;
• and
• a plunger assembly comprising a plunger head slidably disposed within the syringe barrel and a plunger rod associated with the plunger head, the plunger head separating the chamber of the syringe barrel into a first chamber adjacent the first end and a second chamber adjacent the second end,
• wherein a pulling movement on the plunger rod causes movement of the plunger head toward the first end of the syringe barrel causing the syringe contents to be expelled through the opening located at the first end.

A method of delivering a fluid, comprising:

• providing a syringe assembly having a reduced profile prior to use comprising:
• a syringe barrel having an inside surface defining a chamber, a first end, and a second end having an opening therethrough;
• an opening located at the first end, the opening being offset from a central axis of the syringe assembly;
• a vent located adjacent the second end;
• a plunger assembly comprising a plunger head slidably disposed within the syringe barrel and a plunger rod associated with the plunger head, the plunger head separating the chamber of the syringe barrel into a first chamber adjacent the first end and a second chamber adjacent the second end;
• providing an actuator portion at least partially extending outside the first end of the syringe barrel, said actuator portion being associated with the plunger rod;
• and
• applying a pulling force to the actuator to cause the plunger rod and plunger head to move within the syringe barrel toward the first end of the syringe barrel causing the syringe contents to be expelled through the opening located at the first end.
