Description
Technical field
This utility model belongs to medical instruments field, is specifically related to a kind of external heart pump.
Background technology
Heart is the most important organ of human body, and its major function relies on the blood circulation that its kinetic pump function is whole body to provide power, maintains the normal operation of pulmonary circulation and body circulation.Heart failure refers to the class heart disease caused by Cardial pump function exhaustion, is the coexpress in whole latter stage of all kinds of cardiovascular disease such as hypertension, coronary heart disease.Can be divided into acute and chronic heart failure, the acute heart failure state of an illness is dangerous, and mortality rate is high.And chronic heart failure is described as " cancer " in cardiovascular disease always.Acute cardiac Pump failure caused by the cause of disease such as acute myocardial infarction and severe myocarditis, often there is cardiogenic shock in patient, mortality in acute phase is high, and current existing curative effect of medication is not good.The usual course of disease of chronic heart failure reaches 5-10, constantly worsens and needs repeated hospitalization to treat, at present for advanced chronic Worsening heart failure patient, especially merge hypotensive patient medication's poor effect at terminal stage of a disease patient Chang Yin Cardial pump function.
For above-mentioned two situations, have also been developed the Cardial pump function adjuvant therapy device of many non-drug at present in recent years, mainly contain with Types Below: 1, implanted, comprises bi-ventricular pacemaker, left ventricular assist device; 2, non-built-in mode, comprises blood filtering machine, intra aortic balloon counterpulsation system, external membrane lung system.Embedded type device present situation: bi-ventricular pacemaker is only applicable to those small part Patients with Chronic Heart Failure merging cardiac conduction disturbances, effective percentage about 70% is invalid to acute cardiac Pump failure.Left ventricular assist device power-driven system only can maintain about 3 months, therefore can only be used as the transition before heart transplant operation.Non-implanting device present situation: apply more general blood filtering machine in existing non-built-in mode, its principle is identical with nephropathy haemodialysis control unit, its effect is only limitted to the moisture getting rid of retention in body, and to causing the acute lung edema that sb.'s illness took a turn for the worse without obvious mitigation, and hypotensive is inapplicable.Its principle of intra aortic balloon counterpulsation system passes through diastole, IAB pressurizes, improve vasodilation pressure, improve the perfusion of remote organization, good auxiliary therapeutic action is had to the organ perfusion deficiency caused by hypotension, but to the pulmonary edema unsatisfactory curative effect caused by Cardial pump function exhaustion.External membrane lung system is the most effective known at present Cardial pump function exhaustion auxiliary treatment equipment, its principle is scaled down version cardiopulmonary bypass unit, blood draws extracorporeal oxygenation, its existing problems to carry out short term therapy (the longest 20 days), cannot repeated multiple times treatment be carried out, and somewhat expensive.
Utility model content
One of the purpose of this utility model be for solve existing heart pump therapeutic effect poor, can only short term therapy, somewhat expensive problem, provide that a kind of cost is low, good effect, can the external heart pump of repeated multiple times treatment.
This utility model provides a kind of external heart pump, comprises dynamical system and turn of tidal stream conduit, and described dynamical system comprises centrifugal pump, motor, input pressure monitor, output end pressure monitor, control system; Described turn of tidal stream conduit comprises input turn of tidal stream conduit and exports turn of tidal stream conduit;
Described motor one end connection control system, the other end connects centrifugal pump, and described control system connects motor, input pressure monitor and output end pressure detector respectively, and control system controls driven by motor centrifugal pump and operates and monitor input and output pressure; Described centrifugal pump is provided with input interface and output interface, input interface to connect after input pressure monitor again with input turn of tidal stream tubes connection, output interface to connect after output end pressure detector again with output turn of tidal stream tubes connection.Described input turn of tidal stream conduit is placed on left atrium by atrial septal puncture, and export turn of tidal stream conduit and be placed in aorta, blood is drawn from left atrium, leads back in body from aorta.
Further, described input turn of tidal stream conduit is rounded with output turn of tidal stream conduit nearly heart end front end, and tube wall has side opening.
Further, described input turn of tidal stream conduit scribbles heparin coating with output turn of tidal stream pipe inner wall.
Further, described centrifugal pump is replaceable centrifugal pump.
Further, described centrifugal pump outfan can arrange secondary rear pump.
The beneficial effects of the utility model are: external heart pump of the present utility model fully for cardiac failure occur core link, i.e. left ventricular systolic dysfunction, cause left atrium and the pulmonary vein blood stasis of blood stagnant, and Patients with Lung Oxygenation function is normal.By interatrial septum of puncturing under x-ray, conduit is placed on left atrium, by in left atrium fully the blood of oxygenate introduce in external kinetic pump, pump into after being pressurizeed by centrifugal pump in ascending aorta, thus get around the left ventricle of exhaustion, simulate the pumping function of heart in vitro, i.e. external left ventricular assist device.By to the pressure of input and the pressure Real-Time Monitoring of outfan, dynamic adjustments blood flow and pressure, ensure the balance of body circulation, rapid recovery heart failure symptoms.The left ventricular insufficiency left ventricle load that this utility model can make acute pathological changes cause alleviates, myocardium of left ventricle cell is had a rest, promote myocardial cell from acute pathological changes as recovered ischemic injuries and inflammation, the left atrium load of chronic heart failure can be made in addition to alleviate, alleviate pulmonary circulatory stasis, be beneficial to the improvement of pulmonary function, the perfusion of each internal organs of chronic heart failure effectively can be improved by the perfusion of external pump, improve the entirety circulation of body, improve immune status, reducing causes the inducement repeatedly worsened of heart failure as respiratory tract infection, the incidence rates such as intestinal infection.And this device can be such to renal failure hemodialysis, regularly and repeatedly treat, treatment cost is low, good effect.
