Abstract

Przedmiotem wynalazku jest urzadzenie do badania progu pobudliwosci skóry charakteryzujace sie tym, ze zawiera w obudowie zródlo pradowe (3) o natezeniu od 0 do 9 mA regulowane i polaczone z potencjometrem regulujacym (1) zadajacym natezenie pradu zródla pradowego (3) oraz z przelacznikiem wyboru zakresu regulowanego pradu (2) oraz z zewnetrznym amperomierzem pradu stalego (4), przez który przeplywa prad do mostka H(7) polaczonego z elektrodami wykonawczymi (9) przykladanymi do skóry oraz z mikrokontrolerem sterujacym mostkiem H(6) polaczonym z przelacznikiem sekwencyjnego wyboru czestotliwosci pradu elektrod (8) oraz ze wskaznikiem czestotliwosci pradu elektrod (5), korzystnie diodowym.The subject of the invention is a device for testing the skin excitability threshold characterized in that it comprises a power source (3) in the casing with an intensity of 0 to 9 mA regulated and connected with a regulating potentiometer (1) setting the power source current (3) and with a selection switch adjustable current range (2) and with an external DC ammeter (4) through which current flows to the H bridge (7) connected to the operating electrodes (9) applied to the skin and to the microcontroller controlling the H bridge (6) connected to the sequential selection switch electrode current frequency (8) and with an electrode current frequency indicator (5), preferably diode.
