Abstract

conector sem agulha com válvula de retenção com design de válvula assimétrica e suporte de vedação primária. a presente invenção refere-se a um conector sem agulha que pode incluir um alojamento compreendendo um eixo longitudinal central, uma porção de corpo e uma porção de base. a porção de corpo pode incluir uma superfície interna formando uma cavidade interna e uma primeira porta formando uma primeira passagem de fluido para a cavidade interna. a porção de base pode incluir uma seção superior incluindo um suporte de vedação de válvula e uma seção inferior incluindo uma segunda porta formando uma segunda passagem de fluido para a cavidade interna. o conector sem agulha pode ainda incluir uma válvula de formato assimétrico disposta na cavidade interna. a válvula de formato assimétrico pode incluir uma porção de cabeça, uma porção de corpo de válvula que se estende no sentido distal a partir da porção de cabeça e uma parede tendo uma superfície interna formando uma cavidade de válvula. a válvula pode ser acoplada ao alojamento de modo que a superfície interna da válvula na porção de corpo de válvula esteja assentada e apoiada radialmente no suporte de vedação de válvula.
