Abstract
"CONJUNTOS DE CATETER E PROCESSOS DE MOLDAGEM POR INJEçãO E EQUIPAMENTO PARA FAZER O MESMO". Os vários conjuntos de cateter de parte única, conjuntos de cateter integrado de múltiplas partes, e métodos e aparelho para fazer as mesmas são descritas. os conjuntos de cateter de parte única incluem um cubo de cateter integralmente formado com um tubo de cateter para inserção na corrente sang³ínea de um paciente. os conjuntos de cateter integrado de múltiplas partes incluem um cubo de cateter integralmente formado em um tubo de cateter para inserção no fluxo sang³íneo de um paciente. Os conjuntos de cateter da invenção podem ser moldados por injeção em uma etapa única ou em etapas múltiplas injetando fluxos de plástico fundido em uma cavidade de moldes fornecida aqui tal que os fluxos convergem em uma distribuição uniforme sobre a circunferência da luva. O molde pode ter um pino de núcleo desenhado para encaixar na cavidade. Através do uso da distribuição uniforme de fluxos, o pino de núcleo pode ser assentado dentro da cavidade em uma maneira não tensionada. Os conjuntos de cateter da invenção podem ser produzidos de um material único ou de múltiplos materiais.
