Microdermabrasion device

Abstract

A treatment tool and tissue collection system, for removal of outer layers of skin to provide a revitalized, fresh skin surface, and a method of using same, comprising a abrasive tipped tool mounted on the end or within the end of a hollow tube, said tube being connected to a source of vacuum. The vacuum aids in maintaining intimate contact between the abrasive tip and the skin during the treatment process and transports the removed tissue to a collection container. The abrasive surface within the tube is a motor driven abrasive pad. Contact between the pad and the abrasive disk is brought about or increased by application of a vacuum through the tube to the skin surface.

1. A microdermabrasion device for removing portions of the outer layers of a skin surface comprising:
 a source of a vacuum, and 
 a tube with an abrasive treatment tip therein for dislodging cells from the skin surface being treated, the tube being attached to the source of vacuum so that a lumen through the tube has a reduced pressure therein which is less than the ambient pressure surrounding the tube, the tube having a first end, said first end having an opening therein for applying the reduced pressure within the tube to the skin surface, said vacuum causing the skin surface being treated to have an increased area of contact with the abrasive tip, the vacuum also functioning to collect tissue or cells removed from the skin surface being treated wherein the abrasive treatment tip is a rotatable an abrasive pad located within and the tube adjacent to the opening of the first end configured to rotate at least 360° within the tube, and 
 a collection filter disposed between the treatment tip and the source of vacuum so that all particulate matter entering the at least one opening in the tube is collected therein. 
 
     
     
       2. The device of  claim 1  wherein the source of vacuum is a vacuum pump enclosed within a housing, the housing have having means thereon for monitoring and controlling the level of vacuum delivered. 
     
     
       3. The device of  claim 1  further including means for varying the level of reduced pressure applied through the treatment tip. 
     
     
       4. The device of  claim 3  wherein the means for varying the level of reduced pressure applied through the treatment tip is a valve mechanism mounted in the treatment tube. 
     
     
       5. The device of  claim 3  wherein the means for varying the level of reduced pressure applied through the treatment tip is a valve mechanism in operative connection to the source of vacuum. 
     
     
       6. The device of  claim 1  wherein the abrasive tip has diamond, aluminum oxide, silicone carbide, silicon oxide or metal nitride particles attached thereto. 
     
     
       7. The device of  claim 1  wherein the abrasive tip has a mechanically or chemically created roughened surface. 
     
     
       8. The device of  claim 1  further including a collection filter disposed between the treatment tip and the source of vacuum so that all particulate matter entering the at least one opening in the tube is collected therein. 
     
     
       9. A microdermabrasion device for performing micro-abrasion of a skin surface comprising a tubular device with a lumen there through, the tubular device having a first end with a rotatable abrasive tip having an abrasive surface, the abrasive tip mounted on a multiple RPM drive to provide rotary motion, the first end having an opening therein, the rotatable tip positioned inside the lumen and adjacent the opening, and means on a second end thereof for attachment to a source of a vacuum to apply a negative pressure to a surface to be treated, said vacuum causing increased contacted contact between the skin surface and the abrasive surface, and a collection filter disposed between the first end and the source of vacuum so that all particulate matter entering the opening in the tube is collected therein. 
     
     
       10. The tubular device of  claim 9  wherein the abrasive surface on the tip comprises crystalline diamond pieces permanently secured to said tip. 
     
     
       11. The tubular device of  claim 9  wherein the abrasive surface on the tip comprises crystalline aluminum oxide pieces permanently secured to said tip. 
     
     
       12. A method of treating the skin surface of a patient to remove surface cells and reduce undesirable skin blemishes comprising:
 providing a microdermabrasion device comprising a tubular treatment tool with a rotatable abrasive skin contacting surface within an open distal end of a lumen of the treatment tool, 
 providing a multiple RPM rotational drive, 
 providing a pressure through the lumen within the tubular treatment tool, the pressure being less than ambient pressure surrounding the treatment tube, 
 bringing the rotatable abrasive skin contacting surface into contact with the skin surface to be treated while said lesser pressure is delivered to the skin surface through the lumen and moving the abrasive skin contacting surface across the skin surface wherein while the rotatable abrasive skin contacting surface is a motor driven abrasive disk located within the lumen of the treatment tool and adjacent the open distal end is rotated by the rotational drive, said vacuum providing increased contact between the skin surface and the abrasive disk. 
 
     
     
       13. The method of  claim 12  wherein the abrasive skin contacting surface has an abrasive crystalline material adhered thereto. 
     
     
       14. The method of  claim 13  wherein the abrasive skin contacting surface is formed by a machining process. 
     
     
       15. The method of  claim 14  wherein the abrasive crystalline material is diamond crystals. 
     
     
       16. The microdermabrasion device of claim 1 further including a delivery conduit mounted on the tube for providing chemicals to enhance abrasion and liquids to reduce friction, or irrigate or cool the skin surface and remove material loosened from the skin surface. 
     
     
       17. The microdermabrasion device of claim 9 further including a delivery tube mounted on the tubular device for providing chemicals to enhance abrasion and liquids to reduce friction, or irrigate or cool the skin surface and remove material loosened from the skin surface. 
     
     
       18. The method of claim 12 further including providing through the tubular treatment tool and to the skin surface chemicals to enhance abrasion and liquids to reduce friction, or irrigate or cool the skin surface and remove material loosened from the skin surface while the abrasive skin contacting surface is moved across the skin surface being treated.
