Abstract
A device for controlling the dispensing of pigments suspended in solution for reciprocating needles that penetrate the skin. For use in an apparatus of the type which includes a tip assembly, including a needle secured to a reciprocating driven by a motor, an adapter member is disclosed having a generally axially aligned chamber, a portion of which is manually secured to the tip assembly. The adapter member also defines an inclined chamber for receiving a pigment-containing reservoir member with a transfer tube. A weighted wire has a portion located within the transfer tube. The wire includes a second portion which resides within the reservoir member so that when the reservoir member with its pigment solution and wire is inserted into the adapter member, reciprocation of the tip assembly causes the wire to agitate the pigment suspension while controlling flow of the pigment-containing solution to the lower portion of the axially aligned chamber in the adapter member, and hence to the needle.
