Mixing syringe and method of use

A syringe mixing device comprising:

• a cylindrical syringe housing having an internal chamber for holding material, a distal end and a proximal end, the proximal end has an enlarged lip or ring around an external surface of the cylindrical syringe housing and adjacent the proximal end being a pair of finger grips;
• an end cap with a proximal end for attaching to the distal end of the cylindrical syringe housing, the end cap having a nozzle configured to pass material ejected from the cylindrical syringe housing;
• a nozzle cap for sealing the nozzle;
• a removable stir rod mixer assembly for mixing material in the internal chamber of the cylindrical syringe housing, wherein the removable stir rod mixer assembly comprises:
• a stir shaft with a mixing paddle at a distal end of the stir shaft, the mixing paddle having a plurality of mixing blades;
• a seal with a central hole for receiving the stir shaft, the seal sized to slide in and seal the internal chamber of the cylindrical syringe housing;
• a seal support configured with a central hole for receiving the stir shaft, the seal support configured to abut a proximal end of the seal to provide rigidity;
• and
• a handle configured to attach to a proximal end of said stir shaft and provide a means to assist in rotating the stir shaft to move the plurality of mixing paddles;
• a large mouth funnel configured to fasten at a throat end to the distal end of the cylindrical syringe housing, the funnel having a slope shaped chamber configured to receive and pass material for mixing into the internal chamber of the cylindrical syringe housing;
• and
• wherein the syringe mixing device includes one or more locking clips, each locking clip configured to lock onto the enlarged lip or ring at the proximal end of the cylindrical syringe housing;
• the locking clip having a central hollow cylinder for passing the stir shaft for movement linearly and rotationally, a length (L) of the central hollow cylinder limits the travel of the mixing paddles linear movement inside the internal chamber, each locking clip has lateral ends at a proximal end adjacent a hollow cylindrical tube such that the lateral ends can be pushed up against the proximal end of the cylindrical syringe housing and snapped onto the enlarge lip or ring of the cylindrical syringe housing at the lateral ends of the locking clip.
