Microdermabrasion Treatment Heads

Abstract

An abrasive tip is used to exfoliate skin and tissue through abrasive materials integrated in the tip. The tip also delivers fluid to the skin and vacuums the fluid and abraded tissue during treatment. Treated skin will look younger and healthier in appearance. In an implementation, the tip is replaceable and disposable.

         2 . The device of  claim 1  wherein the abrading surface comprises a plurality of bristles coupled to the first side. 
     
     
         3 . The device of  claim 1  wherein the first side of the tip comprises a circular shape. 
     
     
         4 . The device of  claim 1  wherein each fluid channel is a groove formed in the first edge. 
     
     
         5 . The device of  claim 1  wherein there is a split in the collar portion at each point where a fluid channel passes through the collar portion. 
     
     
         6 . The device of  claim 1  wherein the plurality of fluid channels are evenly distributed about the second edge. 
     
     
         7 . The device of  claim 1  wherein the plurality of bristles comprises:
 a first grouping of bristles; 
 a first gap; 
 a second grouping of bristles, wherein the second grouping of bristles is separated from the first grouping of bristles by the first gap, bristles in the second grouping of bristles are positioned closer to other bristles in the second grouping than any bristle in the first grouping; 
 a second gap; 
 a third gap; and 
 a third grouping of bristles, wherein the third grouping of bristles is separated from the second grouping of bristles by the second gap, the third grouping of bristles is separated from the first grouping of bristles by the third gap, bristles in the third grouping of bristles are positioned closer to other bristles in the third grouping than any bristle in the first and second groupings of bristles, and the first, second, and third groupings of bristles are arranged around the fluid opening. 
 
     
     
         8 . The device of  claim 7  wherein the first, second, and third groupings of bristles are arranged in a circle. 
     
     
         9 . The device of  claim 7  wherein distances between bristles in the first grouping of bristles is less than a size of the first gap, is less than the size of the second gap, and is less than the size of the third gap. 
     
     
         10 . The device of  claim 9  wherein distances between bristles in the second grouping of bristles is less than a size of the first gap, is less than the size of the second gap, and is less than the size of the third gap. 
     
     
         11 . The device of  claim 10  wherein distances between bristles in the third grouping of bristles is less than a size of the first gap, is less than the size of the second gap, and is less than the size of the third gap. 
     
     
         12 . The device of  claim 1  wherein the tip comprises a fluid opening on the first side of the tip. 
     
     
         13 . The device of  claim 1  comprising a handle coupled to the tip, wherein the tip is detachable from the handle. 
     
     
         14 . A device comprising:
 a tip comprising an abrading surface coupled to a planar tip structure formed on a first side, wherein the abrading surface comprises a plurality of bristles coupled to the first side;   a collar portion on a second side of the tip, wherein the second side is opposite of the first side, and the collar portion extends perpendicularly to the planar tip structure;   a plurality of fluid channels formed on the second side of the tip, each channel extending through the collar portion through a first edge to a second edge of the tip, wherein the second edge of the tip is perpendicular to and touches the first side, and an angle between the first side and the first edge is less than ninety degrees; and   at least one key notch, formed on the collar portion between two channel openings, wherein a surface of the collar portion is perpendicular to the first side.   
     
     
         15 . The device of  claim 14  comprising a tip holder having a central opening, wherein the tip is at least partially in the central opening. 
     
     
         16 . The device of  claim 15  wherein the tip is snap coupled to the tip holder. 
     
     
         17 . The device of  claim 15  comprising a handle coupled to the tip and the tip holder, wherein the tip and tip holder are detachable from the handle. 
     
     
         18 . The device of  claim 15  wherein the tip holder comprises fluid channels coupled to the fluid channels of the tip. 
     
     
         19 . The device of  claim 15  wherein the fluid channels are U-shaped channels formed on the second side of the tip. 
     
     
         20 . The device of  claim 14  wherein the plurality of bristles comprises:
 a first grouping of bristles; 
 a first gap; 
 a second grouping of bristles, wherein the second grouping of bristles is separated from the first grouping of bristles by the first gap, bristles in the second grouping of bristles are positioned closer to other bristles in the second grouping than any bristle in the first grouping;
