Claims52
A delivery device comprising:
- a barrel holding a liquid for delivery;
- a finger flange assembly coupled to said barrel, said finger flange assembly comprising:
- a first flange and a second flange each extending laterally from opposite sides of said finger flange assembly, wherein the first flange and the second flange each curve toward said barrel;
- and
- a plunger coupled to said barrel and passing through said finger flange assembly, said plunger comprising a disc-shaped head.
A finger flange assembly configured for use with a delivery device, the finger flange assembly comprising:
- a substantially cylindrical trunk having a proximal end and a distal end, wherein the distal end of said trunk is configured to attach to the barrel of the delivery device;
- and
- a first flange and a second flange each extending laterally from opposite sides of the proximal end of said trunk, wherein said first flange and said second flange each curve toward the distal direction and terminate in respective first and second flange tips, wherein said first flange and said second flange each become narrower as they extend toward the respective first and second flange tips.
A plunger configured for use with a delivery device, the plunger comprising:
- a circular disc-shaped head at a proximal end of the plunger;
- and
- a rod coupled to and extending distally from said head,
- wherein the proximal surface of said head includes a spherical dimple.
