Claims22
An injectable material delivery device, comprising:
- a barrel having an internal chamber;
- a plunger at least partially disposed within the internal chamber of the barrel;
- a collapsible mixing blade within the internal chamber, the collapsible mixing blade comprising:
- a base having a top and a bottom;
- a plate having a top and a bottom, with the bottom of the plate connected to the top of the base;
- and
- a collapsible mixing arm with a first end extending from the top of the plat;
- a drive assembly integrated with a distal end of the barrel, the drive assembly comprises:
- a motor;
- an output shaft extending from the motor;
- an output gear connected to the output shaft;
- a mixing blade drive gear meshed with the output gear;
- and
- a mixing blade drive hub connected to the mixing blade drive gear, wherein the mixing blade drive hub is coupled to the collapsible mixing blade;
- a needle hilt integrally formed with the mixing blade drive hub;
- and
- a valve extending from the needle hilt and configured for attachment with a material delivery tube,
- wherein the drive assembly is configured to rotate the collapsible mixing blade within the barrel.

A delivery device, for delivering injectable material comprising:
- a base having a top and a bottom;
- a plate having a top and a bottom, with the bottom of the plate connected to the top of the base;
- a collapsible mixing arm with a first end extending from the top of the plate, wherein the collapsible mixing arm is configured to move between an extended configuration in which the mixing arm is substantially upright to extend along at least a majority of a height of an internal chamber within the injectable material delivery device and a collapsed configuration in which the mixing arm is collapsed, or substantially compressed, onto the top of the plate;
- a drive assembly integrally attached to the injectable material delivery device, the drive assembly comprises:
- a motor;
- an output shaft extending from the motor;
- an output gear connected to the output shaft;
- a mixing blade drive gear meshed with the output gear;
- and
- a mixing blade drive hub connected to the mixing blade drive gear, wherein the mixing blade drive hub is coupled to the collapsible mixing blade;
- and
- a needle hilt integrally formed with the mixing blade drive hub,
- wherein the drive assembly is configured to rotate the collapsible mixing blade within the barrel.
