Abstract
A skin treatment device for home use is provided herein. The device has enhanced safety features and improved operation efficiency. RF energy is delivered under strict control to a relatively small and well localized volume of the skin, avoiding excessive heating of the skin surface. Surface heating is monitored both by direct temperature measurement and by movement monitoring of the device to ensure proper use and prevent skin overheating and the pain associated therewith.
Claims16
A skin treatment device comprising:
- a plurality of linearly arranged electrodes adapted to directly contact a contacting surface of a user's skin non-invasively;
- a radio frequency (RF) generator, arranged to deliver RF energy to the skin via the electrodes;
- and
- a control unit arranged to control RF energy delivery by the RF generator to the skin according to a specified transmission plan, the specified transmission plan comprising controlling relative electrode polarities to yield at least one pair of adjacent electrodes with the same polarity to concentrate the delivered RF energy to a specified skin volume at a predetermined depth below the electrodes, wherein the control unit is adapted to elevate a temperature of the specified skin volume with respect to the contacting surface of the skin, while keeping the contacting surface of the skin below a specified temperature threshold.
A skin treatment method comprising delivering RF energy via a plurality of linearly arranged electrodes to a contacting surface of a user's skin, non-invasively, wherein the electrodes contact the contacting surface of the skin, according to a specified transmission plan, the specified transmission plan comprising controlling relative electrode polarities to yield at least one pair of adjacent electrodes with the same polarity to concentrate the delivered RF energy to a specified skin volume at a predetermined depth below the electrodes, to elevate thereby elevating a temperature of the specified skin volume with respect to the surface of the skin while keeping the contacting surface of the skin, which contacts the electrodes, below a specified temperature threshold.
A skin treatment device comprising:
- a plurality of linearly arranged electrodes adapter to directly contact a contacting surface of a user's skin, non-invasively;
- a radio frequency (RF) generator, arranged to deliver RF energy to the skin via the electrodes;
- a temperature sensor positioned in a vicinity of the electrodes;
- a motion sensor arranged to measure movements of the electrodes with respect to the skin;
- and
- a control unit arranged to:
- control RF energy delivery by the RF generator to the skin according to a specified transmission plan comprising controlling relative electrode polarities to yield at least one pair of adjacent electrodes with substantially the same polarity to concentrate the delivered RF energy to a specified skin volume at a predetermined depth below the electrodes to elevate a temperature of the specified skin volume with respect to the surface of the skin and keep a contacting surface of the skin, which contacts the electrodes, below a specified temperature threshold;
- and
- control RF energy delivery with respect to measurements obtained from the temperature and motion sensors according to a specified safety plan designed to prevent overheating of a specified skin surface area upon operation of the device by an unskilled user, to stop energy delivery upon detection of at least one of:
- a temperature measurement higher than a specified threshold;
- a lack of movement for a time period longer than a specified duration;
- and
- a non-changing measurement from at least one of the temperature sensor and the motion sensor.
