Compact Medication Reconstitution Device and Method

A container usable for lyophilization, storage, and reconstitution of medication having only two parts, one of which is a plug component having a flow path terminating in a side outlet port and a second of which is a barrel component. The barrel component has a spiral mixing channel near its distal end in which powder medication is stored and upon reconstitution, yields a gradient concentration. The inner wall of the barrel includes a longitudinal diluent groove. To connect the plug outlet port with the longitudinal diluent groove, the plug or barrel has a 360° distribution groove encircling the plug and connecting to the plug outlet port. Regardless of what rotational orientation the plug has to the barrel, the diluent will always reach the mixing channel. 1. A reconstitution container device for reconstituting a dried medication , the reconstitution container device comprising: 1) a plug diluent connector port; and', '2) a plug body having a proximal end, a distal end, a side having an outer surface, and an interconnecting lateral diluent channel with a plug outlet port, the plug outlet port opening at the side of the plug body;', 'wherein the plug component has an internal diluent flow path from the diluent connector port to a plug outlet port;, 'a) a plug component, the plug component comprising 1) a wall with an inner surface within which forms a cavity; and', '2) a distal end comprising an injection connector port;', 'wherein the plug component and the barrel component engage each other in a manner where the cavity of the barrel component receives the distal end of the plug component;, 'b) a barrel component, the barrel component comprisingc) a diluent distribution groove;d) a longitudinal diluent flow groove;e) a mixing channel, the mixing channel comprising an elongated mixing channel wall, a fixed input end, and a fixed output end; wherein the fixed output end is connected with the injection connector port; and wherein the mixing channel contains a dried ...
