FIELD: medical equipment; devices for stimulation of muscular activity of organs and systems of human body by pulsed electric current. ^ SUBSTANCE: electric stimulator has stimulating pulse voltage generator and electrode-catheter connected with the generator. Electrode-catheter is provided with at least three contact areas disposed equidistantly along tube of electrode-catheter; contact areas are isolated from each other. Commutator and delay unit are introduced into electric stimulator. Input of commutator is connected to stimulating pulse voltage generator. Contact areas of stimulating electrode-catheter are connected with outputs of commutator through delay unit. After operation on kidneys or ureter is over, multi-electrode stimulating electrode-catheter is put along ureter and is fixed onto it in such a way that contacts of electrode-catheter would touch ureter along its whole length. To restore ureter peristalsis, electric pulse influence starts from supply of stimulation pulses to space between first and second contact areas counting from working end of catheter. Then stimulating pulse voltage is applied to space between second and third contact areas in time gap determined by speed of propagation of peristaltic wave and distance between contact areas. Then stimulating voltage is applied to space between third and fourth contact areas in the same time gap. Stimulation cycle is repeated. Due to ability of sequent excitement of ureter departments which go one after another, the peristaltic wave is excited and kept inside ureter which wave helps to constant removing of urine and dry state of operation seam is provided. Seam recovers faster and broken functions of organ restore. ^ EFFECT: improved efficiency of stimulation of muscular activity. ^ 2 dwg |
