Device for cutaneous therapeutic treatment
First Claim
1. A cutaneous therapeutic treatment device comprising rotary means for rolling along a skin area which is to be treated and fixedly carrying at its exterior surface a plurality of sharply pointed projections for micro-puncturing the skin during rolling of said rotary means therealong, said projections being axially and circumferentially distributed over said exterior surface of said rotary means, a shaft extending through said rotary means and supporting the same for free rotary movement, an elongated body extending parallel to said shaft and means fixing said body to said shaft so that said shaft and body form a unitary structure, said exterior surface of said rotary means being situated between said shaft and elongated body while being spaced together with said projections from said elongated body, the latter being formed with an interior longitudinal bore and with a plurality of ports communicating with said bore and the exterior of said body and directed toward said exterior surface of said rotary means, a syringe, and connecting means connecting said syringe to said elongated body in a manner providing from said syringe a handle for manipulating said unitary structure to roll said rotary means along the skin which is to be treated, said connecting means providing communication means between the interior of said syringe and said longitudinal bore whereby said syringe can be manipulated not only to roll said rotary means along an area of skin to be treated but also to supply to said ports a treating agent to be distributed from said ports not only to said exterior surface of said rotary means and the projections carried thereby but also onto the exterior of the skin which is to be treated.

2. The combination of claim 1 and wherein said projections are circumferentially distributed at said exterior surface of said rotary means in circular rows which are respectively in alignment with said ports.
-
3. The combination of claim 2 and wherein said projections are uniformly distributed along each circular row.
-
4. The combination of claim 3 and wherein said rotary means includes a plurality of independent rollers freely turnable on said shaft and each carrying a plurality of said projections which are distributed along a circular row.
-
5. The combination of claim 1 and wherein each of said micro-puncturing projections extends from said exterior surface of said rotary means through a distance of approximately 1 mm.
-
6. The combination of claim 1 and wherein said means fixing said shaft to said elongated body includes a member projecting from one end of said elongated body and fixed to one end of said shaft.
-
7. The combination of claim 6 and wherein said shaft has a threaded connection with said member while said rotary means includes a plurality of independent rollers situated in side by side relation on said shaft so that the latter can be removed from said member and from said rollers while said rollers can be readily assembled with said shaft prior to fixing of the latter to said member.
