Abstract
"PROCESSO PARA A CONSTRUçãO DE UM CORAçãO ARTIFICIAL SUSTENTADO POR UMA BOMBA PNEUMáTICA OU BALãO INTRA-AóRTICO". Patente de invenção que respeito a um processo para construção de uma bomba de assistência circulatória ventricular direita ou esquerda, de fácil instalação e manuseio, que possa ser mantida por uma fonte (bomba) pneumática sincronizada ao ciclo cardíaco. Com baixo custo, temos ainda que o mecanismo de trabalho da força pneumática sincronizada ao ciclo cardíaco é fornecida por um aparelho já existente em qualquer hospital, já que a proposta é usar como fonte de ar sincronizada: o balão intra-aórtico, equipamento usado de rotina em todos os hospitais de grande porte. Composta por duas câmaras, sendo a primeira para passagem de ar e a segunda para passagem de sangue, as quais são divididas por uma membrana de silicone. A primeira câmara (de ar) tem um tubo de entrada e saída de ar injetado e aspirado pela bomba pneumática ou balão intra-aórtico. A segunda, sendo câmara para bombeamento de sangue, tem uma entrada que recebe o sangue vindo do coração que é direcionada por uma válvula mecânica ou biológica com o fluxo unidirecional, levando o sangue para dentro da segunda câmara. A via de saída contendo válvula mecânica, dirige o sangue bombeado para a aorta, sincronizada ao ciclo cardíaco, bombeando durante a diástole."PROCESS FOR CONSTRUCTION OF AN ARTIFICIAL HEART SUSTAINED BY A PNEUMATIC PUMP OR INTRA-AROTIC BALLOON". The invention relates to a method for constructing an easy-to-install, easy-to-install right or left ventricular circulatory assist pump that can be maintained by a pneumatic source (pump) synchronized to the cardiac cycle. With low cost, we also have the working mechanism of the pneumatic force synchronized to the cardiac cycle is provided by an existing device in any hospital, since the proposal is to use as a source of synchronized air: the intra-aortic balloon, used equipment of routine in all large hospitals. Consisting of two chambers, the first for air passage and the second for blood passage, which are divided by a silicone membrane. The first (air) chamber has an air inlet and outlet tube injected and aspirated by the pneumatic pump or intra-aortic balloon. The second, being a chamber for blood pumping, has an inlet that receives blood from the heart that is directed by a mechanical or biological valve with the unidirectional flow, taking the blood into the second chamber. The mechanical valve-containing outlet pathway directs the pumped blood into the aorta, synchronized to the cardiac cycle, pumping during diastole.
