Abstract

APARELHO DE SUSPENSÃO DE BOLHAS DE AR EM LINHA PARA ANGIOGRAFIA DE TRAJETÓRIA DE FLUIDO DE INJETOR. A presente invenção refere-se a um aparelho para suspensão de bolhas de ar em uma trajetória de fluido de um sistema injetor de fluido, que inclui uma câmara interna com uma parede interior curvada definida dentro do alojamento, uma trajetória de fluido de entrada em comunicação de fluido com a câmara interna e uma trajetória de fluido de saída em comunicação de fluido com a câmara interna. A trajetória de fluido de entrada estendendo-se para dentro da câmara em uma tangente à parede interior curvada, e a trajetória de fluido de saída espaçada a partir da trajetória de fluido de entrada de modo que o fluido que escoa para a câmara interna através da trajetória de fluido de entrada, é direcionado distante da trajetória de fluido de saída. A câmara interna é configurada para criar um vórtice de fluido interno em um fluido de injeção que entra na câmara interna a partir da trajetória de fluido de entrada, e em que o vórtice de fluido interno suspende pelo menos temporariamente uma ou mais bolhas de ar no fluido no vórtice interno e retarda a passagem de uma ou mais bolhas de ar para a trajetória de fluido de saída.
