Abstract

A method and a hand-held device for dermaplaning is disclosed that includes a blade with a safety cage forming an assembly removably mounted to a housing. The dermaplaning device is configured to limit the depth that the blade can penetrate the skin which makes the device safe for use by non-professionals. The dermaplaning device is electrically powered to cause the blade to vibrate at a predetermined frequency. Various embodiments of the hand-held dermaplaning device are disclosed for vibrating the blade. In accordance with an important aspect of the invention, the blade includes a safety guard for limiting the amount of penetration of the blade into the facial skin to enable the device to be safely used by non-professionals.

Claims (19)

1. A portable hand-held dermaplaning device comprising:

a housing for carrying respective components, wherein said respective components comprise:

a blade assembly having a blade and a safety cage, the safety cage being attached to the blade and the blade configured to remain stationary relative to said safety cage during use of the dermaplaning device, said blade assembly removably mounted with respect to said housing, said blade assembly carried by said housing to enable said blade to penetrate an epidermis during use, said safety cage juxtaposed over said blade and constructed and arranged to limit the depth of cut from cutting below the epidermis wherein portions of said safety cage extend below a cutting edge of said blade;

a vibration generator mechanically coupled to said blade assembly for selectively generating vibrations to vibrate said blade assembly at a predetermined frequency;

a power supply for powering the vibration generator;

a switch for selectively connecting said power supply relative to said vibration generator in an on mode of operation, wherein the blade remains stationary relative to the safety cage, and disconnecting said power supply from said vibration generator in an off mode of operation; and wherein said housing is formed to carry said blade assembly, said vibration generator, said power supply, and said switch.

2. The portable hand-held dermaplaning device as recited in claim 1 , wherein said vibration generator includes a piezo-electric crystal.

3. The hand-held dermaplaning device as recited in claim l, wherein said vibration generator includes a motor and an eccentric rotary load.

4. The hand-held dermaplaning device as recited in claim l, wherein said vibration generator includes a piezo-electric crystal and a motor and said switch is configured to enable one or the other piezo-electric crystal and said motor to he alternatively selected.

5. The hand-held dermaplaning device as recited in claim l, wherein said blade extends along an axis generally parallel to a longitudinal axis of said main housing.

6. The portable hand-held dermaplaning device as recited in claim 1 , wherein said housing includes a handle portion.

7. The portable hand-held dermaplaning device as recited in claim 1 , wherein said blade is a surgical blade.

8. The hand-held dermaplaning device as recited in claim 1 , wherein said power supply includes a battery.

9. The hand-held dermaplaning device as recited in claim 1 , wherein said power supply is an alternating current power supply.

10. The hand-held dermaplaning device as recited in claim 1 , further including a printed circuit board for connecting said switch, said power supply and said vibration generator together.

11. The hand-held dermaplaning device as recited in claim 1 , wherein said safety cage is snapped in place over the cutting edge of the blade.

12. The hand-held dermaplaning device as recited in claim 1 , wherein said safety cage is formed as a comb-like structure.

13. The hand-held dermaplaning device as recited in claim 1 , wherein said safety cage is injection molded over the cutting edge of the blade.

14. The hand-held dermaplaning device as recited in claim 1 , further comprising an LED constructed and configured to illuminate when the dermaplaning device is in use.
