Abstract

"APARELHO PARA A ADMINISTRAçãO DE FLUIDO, E, PROCESSO PARA PRODUçãO DE IMAGEM DE RESSONâNCIA MAGNéTICA". A invenção fornece um aparelho para a administração de fluido compreendendo: um reservatório de fluido de volume variável e um conduto de fluido que leva desse lugar para uma saída de fluido, uma primeira entrada de fluido e uma segunda entrada de fluido; um primeiro detector disposto para detectar o fluxo de fluido entre o dito conduto e o dito reservatório; uma primeira válvula disposta para permitir ou impedir o fluxo de fluido da dita primeira entrada através do dito conduto para dentro do dito reservatório; uma segunda válvula que em uma primeira configuração permite que o fluxo de fluido da dita segunda entrada através do dito conduto para a dita saída e impede o fluxo de fluido do dito reservatório através do dito conduto para a dita saída e em uma segunda configuração permite o fluxo de fluido do dito reservatório através do dito conduto para a dita saída e impede o fluxo de fluido da dita segunda entrada através do dito conduto para a dita saída; um segundo detector disposto para detectar o fluxo de fluido para dentro do dito conduto a partir da dita segunda entrada; e um ativador disposto para controlar a operação das ditas primeira e segunda válvulas.
