Description
Изобретение относится к области медицины и может быть использовано для вспомогательного кровообращения в послеоперационный период.The invention relates to medicine and can be used for auxiliary circulation in the postoperative period.
Известен осевой лопаточный насос для вспомогательного кровообращения, состоящий из рабочего колеса с лопатками, установленного в корпусе и соединенного с гибким валом, установленным в подшипниках, которые запрессованы во втулке, снабженного лопатками спрямляющего аппарата, катетера, закрепленного на гибком валу и установленного на концевике спрямляющего аппарата, при этом число лопаток спрямляющего аппарата больше и некратно числу лопаток рабочего колеса. Крепление катетера к концевику спрямляющего аппарата может быть выполнено в виде резьбы по внутреннему диаметру [1].Known axial vane pump for auxiliary circulation, consisting of an impeller with blades installed in the housing and connected to a flexible shaft mounted in bearings that are pressed into a sleeve provided with vanes of a straightening device, a catheter mounted on a flexible shaft and mounted on the end of the straightening device , while the number of blades of the straightening apparatus is greater than and times the number of blades of the impeller. The catheter can be attached to the end of the straightening device in the form of a thread along the inner diameter [1].
Наиболее близким к заявляемому является устройство для вспомогательного кровообращения, содержащее связанные между собой гибкую канюлю с входными отверстиями, насос с выходными отверстиями и электропривод [2].Closest to the claimed is a device for auxiliary circulation, containing interconnected flexible cannula with inlet openings, a pump with outlet openings and an electric drive [2].
К недостаткам описанного устройства можно отнести достаточно большую длину негнущейся части устройства, обусловленную жестким соединением насосной и двигательной части, отсутствие толкателя, что затрудняет передвижение устройства по кровеносным сосудам.The disadvantages of the described device include a rather large length of the stiff part of the device due to the rigid connection of the pump and motor parts, the absence of a pusher, which makes it difficult to move the device through the blood vessels.
Задачей, на решение которой направлено создание предлагаемого изобретения, является обеспечение возможности использования устройства для вспомогательного кровообращения при минимальном травмировании биологических тканей.The task to which the creation of the invention is directed is to provide the possibility of using the device for auxiliary circulation with minimal trauma to biological tissues.
Поставленная задача решается тем, что в устройстве для вспомогательного кровообращения, содержащем соединенные друг с другом канюлю с входными отверстиями для отсоса крови, насос с выходными отверстиями для выброса крови и электропривод, указанный электропривод выполнен в виде, по крайней мере, двух последовательно соединенных звеньев, каждое из которых включает гибкую муфту, выполненную в виде пружины, залитой вибродемпфирующим материалом и снабженную защитным эластичным корпусом, и электродвигатель, при этом гибкая муфта одного из звеньев соединена с насосом, а электродвигатели - с проводом электропитания, валы насоса и электродвигателей выполнены полыми, а гибкие муфты имеют центральное отверстие для прохождения через них направляющего тросика, выполненного с возможностью изъятия из устройства, и дистальный конец которого выходит из отверстия наконечника гибкой канюли.The problem is solved in that in the device for auxiliary circulation, containing connected to each other a cannula with inlet openings for suctioning blood, a pump with outlet openings for ejecting blood and an electric drive, said electric drive is made in the form of at least two series-connected links, each of which includes a flexible coupling made in the form of a spring filled with vibration-damping material and equipped with a protective elastic housing, and an electric motor, while a flexible coupling of one of Venyev is connected to the pump, and the electric motors are connected to the power supply cable, the shafts of the pump and electric motors are hollow, and the flexible couplings have a central hole for passing through them a guide cable made with the possibility of removal from the device, and the distal end of which leaves the tip of the flexible cannula.
На фиг.1 представлено заявляемое устройство. На фиг.2 размещение устройства в сердце.Figure 1 presents the inventive device. Figure 2 placement of the device in the heart.
Устройство содержит гибкую канюлю 1 с входными отверстиями 2, связанную с насосом 3 с выходными отверстиями 4. Электропривод выполнен из нескольких звеньев, каждое из которых включает гибкую муфту 5, выполненную в виде пружины 6. Электродвигатели 7 соединены с подводом электропитания 8.The device comprises a flexible cannula 1 with inlet openings 2, connected to the pump 3 with outlet openings 4. The electric drive is made of several links, each of which includes a flexible coupling 5 made in the form of a spring 6. Electric motors 7 are connected to the power supply 8.
В полых валах насоса 3 и электродвигателей 7 размещен с возможностью изъятия направляющий тросик 9.In the hollow shafts of the pump 3 and electric motors 7 is placed with the possibility of removal of the guide cable 9.
Гибкая муфта 5 может быть конструктивно выполнена в виде цилиндрической пружины с прямоугольным сечением витков, которая залита вибродемпфирующим материалом и имеет центральное отверстие для прохождения направляющего тросика 9.Flexible coupling 5 can be structurally made in the form of a cylindrical spring with a rectangular cross-section of the turns, which is filled with vibration damping material and has a Central hole for the passage of the guide cable 9.
Устройство используют для вспомогательного кровообращения при выраженной левожелудочковой недостаточности.The device is used for auxiliary circulation with severe left ventricular failure.
Через бедренную артерию (или другим способом) через артериальный клапан вводят устройство в левый желудочек сердца. Введение осуществляют при помощи направляющего тросика 9.A device is inserted through the femoral artery (or in another way) through the arterial valve into the left ventricle of the heart. The introduction is carried out using a guide cable 9.
Устройство занимает положение, показанное на фиг.2, когда гибкая канюля 1 находится в левом желудочке, а выходные отверстия насоса 3 в аорте.The device occupies the position shown in figure 2, when the flexible cannula 1 is in the left ventricle, and the outlet of the pump 3 in the aorta.
После размещения устройства в сердце защитный эластичный корпус муфты 5 каждого звена распрямляется за счет собственных сил упругости, обеспечивая соосность электродвигателей 7. Извлекают из устройства направляющий тросик 9. При включении электропитания через подвод 8 электропривод 5, 6, 7 приводит во вращение шнековый насос 3, который через входные отверстия 2 гибкой канюли 1 отсасывает кровь из левого желудочка в аорту. Выброс крови осуществляется через выходные отверстия 4 насоса 5.After placing the device in the heart, the protective elastic case of the coupling 5 of each link is straightened due to its own elastic forces, ensuring the alignment of the electric motors 7. The guide cable is removed from the device 9. When the power is turned on through the supply 8, the electric drive 5, 6, 7 drives the screw pump 3, which through the inlet 2 of the flexible cannula 1 draws blood from the left ventricle into the aorta. Blood is ejected through the outlet 4 of the pump 5.
Устройство для вспомогательного кровообращения работает в непрерывном режиме и обеспечивает адекватный выброс крови из левого желудочка, осуществляя функцию поддержки работы сердца.The device for auxiliary blood circulation works in a continuous mode and provides an adequate discharge of blood from the left ventricle, performing the function of supporting the work of the heart.
Когда отпадает необходимость в поддержке работы сердца, устройство выводится через бедренную артерию или иным способом с помощью проводов питания.When there is no need to support the work of the heart, the device is displayed through the femoral artery or in another way using the power wires.
В концерне "Энергия" изготовлены макетные образцы описываемого устройства, работоспособность которых была проверена в лабораторных условиях.In the Energia concern, prototypes of the described device were made, the operability of which was tested in laboratory conditions.
