摘要：
The invention relates to the field of medical technology, specifically to defibrillators, and can be used in medical institutions for reanimation, cardio surgery and intensive therapy departments and for departments of emergency aid, and also in pre-hospital stages of medical aid. The device for forming a bipolar signal comprises an electric power accumulator, electronic controllable switches which commutate said electric power, and a circuit for controlling said switches. In order to form a signal of positive and negative polarity, an electric power accumulator, which is connected to a circuit of consecutively connected switches, is set up. Each of the switches is connected in parallel to a resistor. The circuit for controlling the switches in order to change the pulse shape controls the connection of the electronic switches and circuit for forming the bipolar signal. The circuit for forming the bipolar signal consists of four switches consecutively connected to the electric power accumulator and to the circuit for changing the pulse shape in such a manner that, when the first and fourth switches are connected up, a current via a load flows in the direction forming a signal of positive polarity and, when the second and third switches are connected up, a current via a load flows in the direction forming a signal of negative polarity. The signals for controlling the electronic switches comes from the control circuit for forming the bipolar signal. The technical result of the present invention comprises simplifying the electric circuit.Изобретение относится к области медицинской техники, а именно, к дефибрилляторам и может найти применение в медицинских учреждениях для отделений реанимации, кардиохирургии, интенсивной терапии, отделений неотложной скорой помощи, а также на догоспитальных этапах медицинской помощи. Устройство формирования биполярного сигнала содержит накопитель электрической энергии, коммутирующие ее электронные управляемые ключи и схему управления эти
