Abstract

"ACIONADOR ENERGIZADO A PRESSãO DE AR PARA DISPOSITIVOS AUXILIARES VENTRICULARES PNEUMáTICOS". A presente invenção refere-se a um acionador para um dispositivo auxiliar ventricular pneumático (VAD) que é energizado por ar pressurizado, oxigênio ou qualquer outro gás comumente disponível nas salas de hospital, unidades de tratamento intensivo e salas de operação. O acionador pode proporcionar tanto a pressão ejetora de sangue (sístole) como vácuo de encher sangue (diástole) ao VAD. O acionador é controlado por um computador/controlador digital por meio de sensores de pressão e volume e válvulas eletromecânicas. O bombeamento ventricular é realizado por um pistão carregado de mola ou fole. O computador pode regular ativamente a pressão ventricular sistólica máxima, vácuo diastólico máximo, taxa de ciclagem e/ou volume de ejeção (dependendo da modalidade de operação). O acionador é, também, capaz de automática e periodicamente ventilar a linha de acionamento para eliminar a condensação e ar impuro. A ausência de um motor ou bomba elétrica torna o dispositivo pequeno, seguro, fácil de manipular e menos dispendioso.
