摘要：
The utility model refers to the technical means of medical use, namely the electrocardiographic technique for recording the cardiac biopotentials on the surface of the human body, and is designed to provide metrological verification, certification and production testing of electrocardiographs in testing centers, laboratories and on-site. The technical result of the proposed technical solution is to increase the ergonomics of the simulator with its autonomous (outside the computerized stand) application. This technical result is achieved due to the fact that in the well-known simulator for metrological verification and testing of electrocardiographs, which contains a Universal Serial Bus interface USB 2.0 for communication with a personal computer, a memory unit and a display connected to a microcontroller, the fourth and fifth outputs of which are connected respectively to the audio indication unit and to the first input of the 8-channel digital-to-analog converter (DAC), as well as the stabilized reference voltage generating unit whose output is connected to the second input of the 8-channel DAC, each of whose outputs connected to the input of the corresponding channel of the 8-channel low-pass filter, a 8-channel patient equivalent connection unit and a 8-channel chain termination simulator, 8 outputs of which tsya outputs simulator intended for connection to the electrodes L, F, C1 - C6, respectively, as well as a series connection of a 2-channel unit equivalents patient connections and a 2-channel unit simulate an open circuit, whose outputs are the outputs of the simulator, intended for connection to the electrode N and the reference R electrode, respectively, whereby both inputs of the 2-channel patient equivalent connection block are connected to the analog ground. 3 z.p. f-ly, 5 ill.Полезная модель относится к техническим средствам медицинского назначения, а именно к электрокардиографической технике регистрации биопотенциалов сердца на поверхности тела челов
