摘要：
FIELD: medicine.SUBSTANCE: device comprises an electric motor connected to a crank mechanism connected to a piston located in a cylinder. The device contains a controller. One part of the cylinder working cavity, separated by the piston, is connected to the air cavity of the first artificial ventricle and to two counter-turned check valves. The working cavity is connected to a pressure sensor and a two-line electromagnetic distributor. The distributor is configured to communicate with the atmosphere at the forward stroke of the piston, after blood discharge from the first artificial ventricle and during the reverse stroke of the piston after filling of the first artificial ventricle with blood. Another part of the cylinder working cavity, separated by the piston, is connected to the air cavity of the second artificial ventricle. The other cavity is connected to an additional counter-turned check valve, an additional pressure sensor and an additional two-line electromagnetic distributor. The distributor is configured to communicate with the atmosphere during the reverse stroke of the piston after blood discharge from the second artificial ventricle and during the forward stroke of the piston after filling of the second artificial ventricle with blood. The controller is connected to both pressure sensors and both electromagnetic distributors.EFFECT: provision of synchronous operation of two artificial ventricles, with a ratio of systole-diastole phases, approximating the physiological values.3 dwgИзобретение относится к медицинской технике, а именно к аппаратам вспомогательного кровообращения и искусственного сердца и может быть использовано в качестве носимого автономного привода пневматических искусственных желудочков. Устройство содержит электродвигатель, соединенный с кривошипно-шатунным механизмом, соединенным с поршнем, размещенным в цилиндре. Устройство содержит контроллер.
