FIELD: medicine.
SUBSTANCE: invention relates to medical equipment. Monopolar needle electrode for registration of electric activity of GIT organs of animals contains needle (2), cable (3), case (1) and electrode fixer (4). Case (1) tightly envelopes needle (2), connected with cable (3). Electrode fixer (4) is made with possibility of putting up with tension on needle (2) tip, brought out of biological tissues. Case (1) is made in form of polymer bushing, which is filled with fixing substance with ratio of its length to its diameter being not less than 3:1. Working part of needle (2) projects from middle part of lateral surface of case (1). Cable (3) projects from one of case (1) butt ends.
EFFECT: application of the invention will make it possible to increase reliability of electrode fixation in wall of GIT organ.
