METHOD AND SYSTEM FOR ELECTROKINETIC INTRODUCTION OF MATTER Russian patent published in 2006 - IPC A61N1/30 

FIELD: electrokinetic introduction of matter (for example, medicine) into tissue.

SUBSTANCE: method and system can be used for electrokinetic introduction of matter into tissues to meet specific criterion of risk for medical equipment which supplies current to patient's skin. Electrokinetic system has ac source with preset frequency, curing electrode, counter-electrode and ancillary electrode connected with ac source, and rectifying circuit among electrodes which is connected with ac source. Electrodes are made for make electric contacts among them and tissue. Curing electrode supplies electric current to area of tissue where matter is introduced. Method of introduction of matter into tissue is based upon delivery of matter into area where the matter should be introduced later. For the purpose, three electrodes are mounted (one of which ones has to be curing electrode); current, coming from ac source wit preset frequency, is subject to rectification, and rectified current is passed through electrodes when they are in electric contact with tissue. In this case rectified current goes through curing electrode. Device for electrokinetic introduction of matter in tissue is made in such a manner, that part of its external surface has shape is adapted to embrace patient's arm from inside to allow patient manipulating with the arm. System also has three electrodes made of current-conducting material. One of electrodes has to be tactile and it is mounted onto mentioned part of structure to make contact with patient's arm. Autonomous ac supply is placed inside structure. One terminal of ac supply is connected with tactile electrode and the other one - with curing electrode. System has rectifying circuits which are connected with a source and with electrodes, one of which electrodes has to curing one.

EFFECT: reduced risk of letting current go through patient's body.
