US Patent 9384947 Cold plasma treatment devices and associated methods

A cold plasma mask application device for delivery of a cold plasma to the face of a patient. An appropriate gas is introduced into a gas containment area that is energized by one or more electrodes that receive energy from a pulsed source. The plasma can be prevented from contact with the patient's face, or can be allowed to make contact with the patient's face at the appropriate treatment area. A three-layer approach to the manufacture of the cold plasma mask application device is also described. Such a device and method can be used to treat acne as well as complex facial wounds such as those resulting from trauma, melanoma, and other cancers of the face, rosacea, and psoriasis.
