Abstract
The utility model relates to a whole heart accessory pulsation ballonet, the shape of which takes the shape of a foldaway bag, the two sides of which are respectively provided with a button type alive button and button, the top of which is provided with a connecting belt, and the bottom of which is provided with a single cavity ballonet guide pipe connected with an air pump. The device of the utility model wraps the surface of the left and the right ventricles. The ballonet of the device is connected with the air pump through a guide pipe, releases the air rhythmically through the air pump and presses the ventricles regularly so as to increase the blood output in each pulsation. The operation to the utility model does not need the anti-congealment, which reduces the related syndromes such as the bleeding, the embolism, the infection, etc. and is applicable for the rescue of the patient which lasts for a long time.
Description
This utility model relates to a kind of Full heart beating-aid air bag.
Assist circulation is meant and adopts certain biology or mechanical means, stablizes to reach circulatory function, can roughly be divided into intracardiac type and heart external form.From the sixties, promptly adopt thoracic wall extruding heart successively, open breast and directly push heart, the heart extrusion cup, external counterpulsation, cardiopulmonary bypass, centrifugal pump until the heart transplantation artificial heart etc., can both improve people's cardiac function, prolongs patient's life-span.After the eighties, the aorta endosphere assists counter fighting to become cardiac surgeon's powerful mean, though it can improve patient's diastolic pressure, increase patient's coronary artery blood supply, improve cardiac function, but for some serious patients with cardiac insufficiency, it improves hemodynamic effect not as good as left chamber auxiliary device, sometimes also can be with severe complications.Various in recent years ventricular assist devices also confusingly have report, but substantially all belong to intracardiac type.These devices all need anticoagulant, are improving the hemodynamic while, owing to also contact with blood so that pipeline is continuous with heart, also can produce complication such as heart and injury and blood component destruction, influence the safety and the time limit of its use.Also the someone uses skeletal muscle and holds ventricle surfaces helping ventricular systole, but skeletal muscle needs long resisting fatigue training period, can't use immediately, and its to improve hemodynamic effect limited.Domestic back of in the application of auxiliary circulating equipment, always following in developed country, never what achievement in research.In view of above assist circulation method or device all have its shortcoming, it improves hemodynamic effect certain qualification, thereby develop a kind of more perfect auxiliary circulating equipment, and improve heart patient's salvage success rate effectively, once be cardiac surgeon's pursuit.
The purpose of this utility model is to provide a kind of Full heart beating-aid air bag, and it surrounds the left and right ventricles surface, and bag shape air bag links to each other with air pump by a conduit, by air pump rhythmicity aerofluxus venting, pushes left and right ventricles regularly, makes it to increase the cardiac output of whenever fighting.The rhythmicity that air bag shrinks triggers and is controlled by electrocardio, also can transfer mechanical rhythmicity control to.
This utility model is achieved in that the profile of air bag is collapsible bag shaped structure, and both sides do not have button knot that can be undone by a pull and button, and the air bag top is provided with connecting band, and the bottom is provided with the single chamber balloon catheter that connects air pump.Gasbag ektexine for the terylene silica gel material make than hard coat, inwall is a biocompatibility silica type material preferably.
Below in conjunction with drawings and Examples this utility model is described in detail.
Fig. 1 is a structural representation of the present utility model.
The figure number explanation:
1-air bag, 2-air bag inwall, 3-gasbag ektexine
4-connecting band, 5-button knot that can be undone by a pull, 6-button
7-balloon catheter
Consult shown in Figure 1, the profile of air bag (1) is collapsible bag shaped structure, folding back contacts with left and right ventricle, both sides are provided with button knot that can be undone by a pull (5) and button (6), to be applicable to the heart of different sizes, air bag (1) top is provided with connecting band (4), and the bottom is provided with the single chamber balloon catheter (7) that connects air pump, and it can tolerate+/-120～150 mmhg pressures.Gasbag ektexine (3) is made than hard coat for the terylene silica gel material, and the air bag inwall is a biocompatibility silica type material preferably.Because banded knot that can be undone by a pull is arranged, so applicable to any big microcardia.
This utility model is a kind of novel Full heart beating-aid device, bleeds by the aerofluxus of air pump rhythmicity, pushes left and right ventricles regularly, and making it increases the cardiac output of whenever fighting, and plays auxiliary whole-heartedly function.The rhythmicity that air bag shrinks can trigger control by electrocardio, and is synchronous with heart contraction, also can transfer machinery control to, makes it not only to can be applicable to failure heart, even quiver in the chamber of can be applicable to or beating heart not.This device is a heart external form auxiliary circulating equipment, does not need anticoagulant in the application process, do not produce blood component and destroy, thereby reduced complication such as relevant hemorrhage, thromboembolism, infection, but the long period is applied to give emergency treatment to a patient.
Claims (2)
1, a kind of Full heart beating-aid air bag, the profile that it is characterized in that air bag is collapsible bag shaped structure, and both sides do not have button knot that can be undone by a pull and button, and the air bag top is provided with connecting band, and the bottom is provided with the single chamber balloon catheter that connects air pump.
2, Full heart beating-aid air bag according to claim 1, it is characterized in that gasbag ektexine for the terylene silica gel material make than hard coat, inwall is a biocompatibility silica type material preferably.
