Abstract
resumo patente de invenção: "turbobomba de sangue". a presente invenção refere-se a um impulsor (5), que é rotativamente suportado em uma câmara de bomba (2), inclui várias palhetas (6), as extremidades periféricas internas de algumas das palhetas são acopladas a um eixo de rotação (7) e a extremidade periférica externa de cada uma das palhetas é acoplada a uma parte de acoplamento anular (8). uma base (17) é formada projetando uma parede de fundo de um alojamento (1) ascendentemente, e tem uma superfície periférica externa cilíndrica que corresponde a um espaço dentro da parte de acoplamento anular. um mancal inferior (10) para suportar a extremidade inferior do eixo de rotação do impulsor é fornecido na superfície de topo da base. um elemento de vedação (20) é colocado abaixo das palhetas e veda um espaço dentro da parte de acoplamento anular enquanto deixa uma abertura (21) em torno da rotação. o diâmetro d da base e a largura do espaço radial cr entre a parte de acoplamento anular e a base satisfazem as relações 13,5 mm ? d ? 15,0 mm, e 0,20 ? cr/d ? 0,28. a hemólise causada por tensão de cisalhamento devido à rotação de impulsor é suprimida enquanto assegura o efeito de aumentar a taxa de fluxo na vizinhança do mancal inferior pelo elemento de vedação. 1/1
