System and method for multiple site dispensing or injection

A system for fluid delivery, comprising:

• a syringe body having proximal and distal ends, a syringe interior, and a syringe flange at the proximal end thereof;
• a fluid disposed in the syringe interior;
• a finger flange coupled to the syringe flange;
• a stopper member disposed in the syringe interior;
• a plunger member coupled to the stopper member and having a ratchet portion;
• a push member disposed coaxially around at least a portion of the plunger member and operatively coupled thereto, the push member having an outer telescoping member disposed at a proximal end thereof;
• an inner telescoping member disposed slidably and at least partially in the outer telescoping member and operatively coupled thereto;
• and
• a thumbpad disposed coupled to a proximal end of the inner telescoping member,
• wherein the finger flange comprises a proximally projecting tubular member,
• wherein a distal end of the push member is disposed in the proximally projecting tubular member,
• wherein the proximally projecting tubular member of the finger flange defines a proximally facing surface, and
• wherein the outer telescoping member of the push member defines a distally facing surface configured to interfere with the proximally facing surface of the proximally projecting tubular member of the finger flange to limit distal movements of the push member relative to the finger flange.
