Fluid skin treatment systems and methods
View Patent ↗The present invention relates to devices for dermatology and more particularly to fluid enhanced skin treatment system for skin rejuvenation that can optionally use an abrasive probe for removing epidermal layers while contemporaneously providing for the infusion of therapeutic fluids into the skin.
1. A microdermabrasion system for treating a tissue for use with a fluid source and a negative-pressure source, the system comprising:
a device body having an applicator end, the applicator end comprising a tissue contact surface having a recess within the applicator end;
at least one fluid opening configured to deliver a fluid from the fluid source to the skin contact surface located towards an outer edge of the recess;
at least one negative pressure opening located at a center of the recess and fluidly coupled to the negative pressure source, such that application of the negative pressure source causes tissue to be drawn into the recess against the tissue contact surface, wherein when the tissue is positioned against the applicator end, the negative pressure source pulls the fluid from the at least one fluid opening; and
at least one vibratory element positioned in the device body, where actuation of the vibratory element causes a vibratory motion of the applicator end such that the tissue contact surface applies a vibratory force to the tissue.
2. The microdermabrasion system of claim 1 , where the tissue contact surface comprises an abrasive surface.
3. The microdermabrasion system of claim 1 , where the tissue contact surface comprises a plurality of annular ridges and a plurality of recesses.
4. The microdermabrasion system of claim 1 , where the at least one vibratory element comprises at least one vibratory element that produces vibration in a single direction relative to the device body.
5. The microdermabrasion system of claim 4 , where the at least one vibratory element produces vibration in the single direction that is perpendicular to an axis of the applicator end.
6. The microdermabrasion system of claim 5 , further comprising at least a second vibratory element that produces vibration in a direction perpendicular to the single direction of the at least one vibratory element.
7. The microdermabrasion system of claim 5 , where the vibratory element is selected from either a linear resonant actuator or a fluid actuator.
8. The microdermabrasion system of claim 1 , where the applicator end comprises a material configured to flex and/or compress slightly when engaging the tissue.
9. The microdermabrasion system of claim 1 , where the tissue contact surface is concave.
10. The microdermabrasion system of claim 9 , where the at least one fluid opening is located adjacent to an edge of the applicator end allowing the negative pressure source to pull the fluid from the at least one fluid opening adjacent to the edge.
11. The microdermabrasion system of claim 1 , where the applicator end comprises an abrasive surface.
12. The microdermabrasion system of claim 1 , where the applicator end comprises at least one aspiration channel.
13. The microdermabrasion system of claim 1 , where the negative pressure source is in fluid communication with a vacuum lumen in the device body, and further comprising a fluid trap in fluid in the device body communication with the vacuum lumen.
14. A microdermabrasion system for treating a tissue and for use with a fluid source and a negative-pressure source, the system comprising:
a device body having an applicator end, the applicator end comprising a tissue contact surface forming a recess having an abrasive finish within the applicator end;
at least one fluid opening configured to deliver a fluid from the fluid source to the tissue contact surface located towards an outer edge of the recess;
at least one negative pressure opening located at a center of the recess and fluidly coupled to the negative pressure source, such that application of the negative pressure source causes tissue to be drawn into the recess against the abrasive finish, wherein when the tissue is positioned against the applicator end, the negative pressure source pulls the fluid from the at least one fluid opening; and
at least one vibratory element positioned in the device body, where actuation of the vibratory element is configured to vibrate in a single axis, where the vibratory element causes a vibratory motion of the applicator end such that the tissue contact surface applies a vibratory force to the tissue.
15. The microdermabrasion system of claim 14 , further comprising at least a second vibratory element that produces vibration in a direction perpendicular to the single axis.
16. The method of claim 14 , where the recessed tissue contact surface comprises a plurality of annular ridges and a plurality of recesses.
17. The microdermabrasion system of claim 14 , where the tissue contact surface is concave and where the at least one fluid opening is located adjacent to an edge of the applicator end such that the negative pressure source pulls the fluid from the at least one fluid opening adjacent to the edge.
