摘要:
The invention relates to medical devices intended to replace the pumping function of the heart in case of partial or complete circuit of the natural ventricles of the heart, and can be used in implantable circulatory support systems.In the housing (1) of the artificial ventricle diaphragm pump disposed with a tight diaphragm seals, electromechanical drive and a pusher (11) which is the actuator body. The pusher (11) is mechanically connected to the lead screw (14) connected to the rotor of the motor (13). On the surface of the pusher (11) from the membrane separator is a metal plate (12) with a polished surface. Membrane separator divides the housing chamber (1) into a liquid chamber (2) and the gas chamber (3). With liquid cavity (2) serving the working chamber of the diaphragm pump is connected to the inlet pipe (7) with an inlet valve (8) and outlet (9) with an outlet valve (10). Under the action of the pusher (11) a membrane separator performs a reciprocating movement. Membrane separator consists of two elastic membranes (4 and 5) separated by a cavity (6) filled with a liquid polydimethylsiloxane. The inner membrane (4) is located by the fluid chamber (2). The outer membrane (5) is mounted on the part of the gas chamber (3). Membranes (4 and 5) are made of polyurethane. The thickness of the outer membrane (5) is greater than the thickness of the inner membrane (4).The technical result is to increase the reliability of the implantable artificial ventricle of the heart, increasing the resource system and ensuring patient safety during long-term operation of the system circulatory support. 4 ZP f ly-2-yl.Полезная модель относится к медицинским аппаратам, предназначенным для замены насосной функции сердца при частичном или полном обходе естественных желудочков сердца, и может использоваться в имплантируемых системах вспомогательного кровообращения.В корпусе (1) искусственного желудочка сердца размещен мембранный насос с герметичным мембранным разделителем, электром
