Inverted cannula for use in reconstituting dry material in syringes

A method of reconstituting a material to be reconstituted, comprising:

• (a) providing a first structure having at least one first inner portion configured to receive at least a portion of a material to be reconstituted, comprising:
• a first proximal opening and a first distal opening, wherein the first distal opening has a first mating structure, and
• a first movable member selectively inserted into said first inner portion to urge out the material to be reconstituted,
• (b) providing a connector device, comprising:
• a first mating portion configured to mate with the first mating structure,
• a second mating portion configured to mate with a second mating structure, and
• a lumen extending between the first and second mating portions and configured to permit communication between the materials in said first and second structures,
• (c) connecting the first mating portion to the first mating structure, thereby causing the lumen to extend through the first mating structure and into the first inner portion,
• (d) providing a second structure having at least one second inner portion configured to receive at least a portion of a reconstituting material, comprising:
• a second proximal opening and a second distal opening, wherein the second distal opening has a second mating structure, and
• a second movable member selectively inserted into said second inner portion to urge out the reconstituting material,
• (e) connecting the second mating structure to the second mating portion,
• (f) urging out reconstituting material from the second inner portion into the first structure via said connector device, thereby mixing the reconstituting material and the material to be reconstituted.

• (d) inserting the material to be reconstituted into the first inner portion,
• (e) cooperatively connecting the first movable member with the first structure,
• (f) providing a second structure having at least one second inner portion configured to receive at least a portion of a reconstituting material, comprising:
• a second proximal opening and a second distal opening, wherein the second distal opening has a second mating structure, and
• a second movable member selectively inserted into said second inner portion to urge out the reconstituting material,
• (g) connecting the second mating structure to the second mating portion,
• (h) urging out reconstituting material from the second inner portion into the first inner portion, thereby mixing the reconstituting material and the material to be reconstituted.
