Abstract

"PROCESSO E APARELHO PARA CONTROLE DE RETORNO EM UM CONJUNTO DE CATETER E AGULHA INTRODUTORA". Um processo é proporcionado para controle da vazão de fluido em um tubo de extensão do conjunto de agulha introdutora para uso como confirmação de retorno. O conjunto de agulha introdutora possui um cateter preso a uma conexão de cateter com um orifício lateral, um tubo de extensão preso ao orifício lateral sobre a conexão de cateter, e uma agulha introdutora com um entalhe adaptado para ser inserido em um furo no cateter. Um tabuado se estende através da agulha e está em comunicação fluida com o entalhe. A agulha possui um diâmetro externo inferior ao diâmetro do furo, assim que um espaço anular é definido entre o cateter e a agulha. O fluido, de modo particular sangue, se encontra a uma pressão e possui uma viscosidade, quando a agulha o acessa. Uma velocidade mínima preferida de fluido através do tubo de extensão é selecionada (de preferência, de pelo menos 25,4 mm por minuto através do tubo de extensão em certas aplicações) . o entalhe e o espaço anular são dimensionados, com base, pelo menos em parte, na viscosidade do fluido e na pressão do fluido, para alcançar a vazão preferida através do tubo de extensão.
