ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention pertains generally to devices for treating skin disorders, and in particular to an apparatus which includes a metal ball tip electrode which is applied to a local area of the skin.
PRIOR ART
Treating facial skin disorders by using galvanic electric current is well known in the art. One such device is disclosed in U.S. Pat. No. 5,413,590 in which the treatment apparatus includes a conical electrode tip for treating localized skin disorders such as black heads and pimples. The skin treatment apparatus has a low voltage battery, including a negative pole connected to a probe having a metal electrode tip, and a positive pole connected to a metal plate which is mounted on a housing to be grasped by a user's hand. The metal plate forms a second electrode connected to the positive pole. The metal electrode tip has a pointed portion at an acute angle in the form of a circular cone of about 30°, thereby preventing the electrode tip from penetrating the skin.
However, since the electrodes of the aforementioned apparatus are separated, the user is inconvenienced by having to utilize two hands to operate the device. Also, the shape of the electrode is sharply pointed, and may not be safe when used by an unskilled person.
An object of the present invention is to provide an apparatus for electrically treating skin disorders which includes a metal ball tip which will not penetrate the skin, and an electrode structure which can be grasped with one hand.
SUMMARY OF THE INVENTION
An apparatus for electrically treating skin disorders comprises a case including a low voltage DC battery and a printed circuit board mounted therein for generating galvanic electricity. An electrode structure includes an electrode tip disposed on one end and connected to a negative pole, and a metal electrode connected to a positive pole. The electrode structure includes a body which is conveniently grasped with only one hand.
The electrode tip comprises a ball bearing such as is used in a ball point pen. The metal electrode is mounted on the body, and has a size and shape that can be contacted by a grasping hand. The printed circuit board includes a galvanic electric generating circuit for generating electric current. The ball tip prevents penetration of the skin when unskilled persons use the apparatus.
