Abstract

a presente invenção refere-se a um dispositivo de coletamento de sangue descartável do tipo de pressão de contato provido com uma estrutura de guia de mola, o dito dispositivo compreendendo um alojamento (1), um núcleo de agulha (2), uma mola (3) e um impulsor (4). a estrutura de guia está disposta sobre o lado externo da mola (3), de modo que a força elástica da mola (3) atua em uma direção de ejeção do núcleo de agulha (2). um mecanismo de travamento está formado por um clipe elástico disposto em uma porção de cauda do impulsor (4) coincidindo com o núcleo de agulha (2). um mecanismo de destravamento está formado por uma porção dianteira da estrutura de guia coincidindo com extremidades do clipe elástico através de superfícies inclinadas de destravamento (10). quando uma pressão de contato é aplicada durante a utilização, o impulsor (4) move para trás dentro do alojamento (1), a porção dianteira da estrutura de guia força as extremidades do clipe elástico para abrir lateralmente sob o efeito das superfícies inclinadas de destravamento (10), e o núcleo de agulha (2) ejeta e perfura sob o efeito da mola (3) após os ganchos (6) separarem de pontos críticos de travamento. a estrutura de guia de mola está conectada no mecanismo de destravamento, de modo que aquela estrutura é inteligentemente utilizada para produzir os dois efeitos de guiar e destravar, por meio disto reduzindo a agitação de ponta de agulha, simplificando a estrutura, e diminuindo custos.
