Abstract
resumo da patente de invenção para: seringa auto retrátil. seringa hipodérmica auto retrátil que possui um invólucro que se estende axialmente para formar um anel e em que o invólucro interage com os componentes da seringa, um cilindro externo fixo no interior ou que forma parte do invólucro e um cilindro interno deslizável montado no interior do cilindro externo para o movimento para trás no interior do cilindro externo, o cilindro interno possui um suporte para instalação de uma seringa hipodérmica ou uma agulha já instalada em um suporte; um êmbolo com um pistão na sua extremidade distal para retirar a dosagem do líquido para o cilindro interno quando o êmbolo é puxado para trás e para injeção da dosagem quando o êmbolo é empurrado para frente; discos de diferentes diâmetros axialmente espaçados no êmbolo engatam com os braços de bloqueio articulados e radialmente rotativos formados na extremidade proximal do invólucro e existem outros elementos de bloqueio associados no cilindro interno e no invólucro que se movem para dentro e para fora em relação aos movimentos para a frente e para trás do êmbolo; uma mola helicoidal é colocada entre o invólucro e o cilindro interno para exercer uma força de retração na agulha contra o cilindro interno para retraí-la no invólucro após terminar a injeção do conteúdo da seringa, ao que um fecho a bloqueia no invólucro.
