Description

УСТРОЙСТВО ДЛЯ ОБЛЕГЧЕНИЯ ДЕЯТЕЛЬНОСТИ СЕРДЦАDEVICE FOR RELIEF ACTIVITY OF THE HEART

1one

Изобретение относитс  к медицинской технике .The invention relates to medical technology.

Известно устройство дл  облегчени  де тельности сердца, содержащее насос кардиосинхронизированного перекачивани  крови, перфузионный катетер и канюли.A device for facilitating cardiac activity is known, comprising a cardiosynchronized blood pump, a perfusion catheter, and cannulas.

Цель изобретени  - снижение травматичности и упрощение хирургических вмещательств при оказании помощи пораженному сердцу, например, при инфаркте миокарда и кардиогенном щоке.The purpose of the invention is to reduce trauma and simplify surgical insertions in assisting the affected heart, for example, in case of myocardial infarction and cardiogenic cheek.

Это достигаетс  тем, что перфузионный катетер снабжен обратными клапанами; всасывающим , установленным на конце катетера, и пагнетающи л, расположенным на рассто нии от конца катетера, завис щем от продольного диаметра внутренней полости левого желудочка .This is achieved by providing a perfusion catheter with check valves; suction, mounted on the end of the catheter, and pagnetasi, located at a distance from the end of the catheter, depending on the longitudinal diameter of the inner cavity of the left ventricle.

На чертеже схематически изображено нредлагаемое устройство дл  облегчени  де тельности сердца.The drawing shows schematically the proposed device for facilitating the functioning of the heart.

Устройство содержит кардиосинхронизированный насос 1 по крови, например камерной, и перфузионный катетер 2 дл  отсасывани  и нагнетани  крови. Перфузионный катетер 2 снабжен всасываюн1им клапаном 3, установленным на его конце дл  всасывани  крови из полости желудочка сердца в насос, и нагнетающим клапаном 4, расположенным на рассто нии 5-20 мм от конца катетера дл  нагнетани  крови из насоса в дугу аорты.The device comprises a cardiosynchronized blood pump 1, for example a chamber pump, and a perfusion catheter 2 for sucking and pumping blood. The perfusion catheter 2 is provided with a suction valve 3 installed at its end to suck blood from the ventricle of the heart to the pump, and with a pressure valve 4 located 5-20 mm from the end of the catheter to pump blood from the pump into the aortic arch.

В камере насоса в конце диастолы и в течении систолы создаетс  разрежение, п кровь из полости желудочка сердца поступает через всасывающий клапан и катетер в камеру насоса. После окончани  систолы в камере насоса создаетс  повышенное давление, откуда кровь через катетер и нагнетающий клапан поступает в дугу аорты.A vacuum is created in the pump chamber at the end of the diastole and during systole, and blood from the ventricle cavity of the heart flows through the suction valve and catheter into the pump chamber. After completion of the systole, an increased pressure is created in the pump chamber, from where blood flows through the catheter and the delivery valve to the aortic arch.
