Claims2
An applicator for use with a handpiece of a hydro dermabrasion device for treating skin, having solution supply and suction apertures, comprising:
- a cylinder that connects to the handpiece, comprising an upper cylinder body with upper and lower walls and a lower cylinder body;
- the upper cylinder body comprising an upper chamber, a lower chamber and a connecting chamber;
- wherein the upper chamber has an open top and a bottom with a supply aperture and a suction aperture and is removably attachable to the handpiece, and the lower chamber and connecting chamber are connected and each has an open bottom;
- the lower cylinder body being dimensioned to slidably fit inside the lower chamber of the upper cylinder body;
- a microneedle array base holder, with a supply lumen and a suction lumen, directly attached to the bottom of the upper chamber of the upper cylinder body;
- a microneedle array base attached to the holder, having supply and suction lumens therethrough and a plurality of microneedles extending therefrom;
- a protective plate having apertures for the microneedles and supply and suction lumens therethrough, attached to the lower cylinder body below the microneedle array base;
- and
- a spring positioned between the lower wall of the upper cylinder body and a ledge around the lower cylinder body;
- wherein the supply aperture, the microneedle array base holder supply lumen, the microneedle array base supply lumen and the protective plate supply lumen are aligned to form a continuous solution supply path through the applicator, the suction aperture, the microneedle array base holder suction lumen, the microneedle array base suction lumen and the protective plate supply lumen form a continuous path through the applicator and the microneedles are reciprocally passable through the safety plate to the treated skin.
