Abstract: FIELD: medicine. 
     SUBSTANCE: group of inventions refers to medical equipment, namely to a cardiac valve prosthesis to be attached to the interventricular septum. Proposed is a cardiac valve prosthesis attached to the interventricular septum, and a method of delivering and disconnecting the prosthesis of the cardiac valve attached to the interventricular septum. Prosthesis of cardiac valve comprises bearing valve frame and fixing device. Bearing valve carcass comprises valve attachment area and artificial valve. Artificial valve is fixedly connected with valve attachment area. Fixing device comprises fixing and supporting area and fixing element. One end of fixing and supporting area is connected to proximal part of valve suturing area. Other end of the fixing and supporting area is connected to the interventricular septum of the patient by means of a fixing element for supporting the prosthesis of the cardiac valve and limitation of the axial movement of the prosthesis of the cardiac valve. Method involves a stage of insertion of a delivery tube carrying a prosthetic cardiac valve into a ring of an atrioventricular valve through an invasive incision in the atrial wall. Method comprises a step of manipulating the delivery tube to detach the fixing means. Method comprises a step of manipulating a tube for delivering a disengagement region of the valve. Method involves a step of manipulating a delivery tube for inserting a fixing element into an interventricular patient's septum. Method includes a stage of extracting a tube for delivery from a human body. 
     EFFECT: technical result is elimination of problem of attachment technology from previous level of equipment, caused by radial expansion of patient's ring of patient's valve, and reduced effect on output circuit after disconnection of bearing frame and prevention of ring reduction of own valve.

Abstract: Изобретение относится к области спорта, в частности к тренировочным средствам, необходимым для подготовки к соревнованиям, формированию технико-тактических действий в защите и развитию у спортсменов волейболистов специальных физических качеств. Недостатком известного устройства является то, что оно не в полной степени решает задачу по осуществлению контроля выполнения технико-тактических действий в защите и оценки уровня подготовленности каждого спортсмена в команде. Данное устройство позволяет фиксировать только период времени от начала отталкивания спортсмена от пола при прыжке до правильного положения его рук в конечной фазе полета. Таким образом, нет возможности полного моделирования игровой ситуации с осуществлением контроля всех технико-тактических действий игрока, включающих реакцию игрока на сигнал начала движения с последующим перемещением до места отталкивания от пола при совершении прыжка и выбор правильного направления для блокирования нападающего удара соперника. Устройство тренажера позволяет контролировать технико-тактические действия игроков в защите с моделированием различных игровых ситуаций, проводить объективную оценку уровня их подготовленности при выполнении одиночного блокирования, что дает возможность тренерскому составу выявлять недостатки и оперативно вносить поправки в процесс тренировки индивидуально для каждого игрока, осуществлять качественный контроль тренировочного процесса в целом. Техническим результатом предложенного изобретения является обеспечение возможности контроля технико-тактических действий игроков в защите и оценки их уровня подготовленности при выполнении одиночного блокирования в момент моделирования различных игровых ситуаций, выявление ошибок и внесение тренерским составом корректировок при выполнении технико-тактических действий в защите, а также интенсификация скоростно-силовой выносливости игроков.
