Patent ID: 7748892

Claim:
A device for substantially uniformly distributing an active ingredient within a transdermal vehicle, said transdermal vehicle being a viscous material and said active ingredient being in particulate form, comprising: a-first container, b-said first container containing a non-uniform mixture of a transdermal vehicle and said active ingredient, said first container having a restricted opening at its proximal end and a first container piston mounted movably within said first container for movement between a first position proximate said first container distal end to a second position proximate said proximal end of said first container, c-second container, said second container having a distal end and a restricted opening at its proximal end and a second container piston mounted movably within said second container for movement from a first position proximate said distal end of said second container to a position proximate said proximal end of second container, said second container being threadedly secured to said first container at said proximal end, said first container restricted opening and said second container restricted opening being in open communication, said first container piston being movable from said position proximate said distal end to a position proximate said proximal end, said movement causing said mixture to be forced from said first container through said first container restricted opening and said second container restricted opening, into said second container, d-support member, said support member having a horizontal base and a vertical element fixed to said horizontal base, said first container and said second container being releasably and rotatably mounted on said vertical element of said support member, parallel to said vertical element, e-drive means, said drive means being mounted on said horizontal base of said support member, and having a drive means piston, said drive means piston being vertically movable relative to said horizontal base and being positioned to contact said first container piston when said first container piston is in a first location proximate said drive means, and being positioned to contact said second container piston when the position of said first container and said second container are rotated relative to said support member horizontal base and said second container piston is in said first location and said first container piston is in a second location, f-a lever member, said lever member being mounted to activate said drive means piston to selectively move said first container piston from said position proximate said distal end to a position proximate said proximal end or said second container piston from said position proximate said second container distal end to a position proximate said second container proximal end.
