Abstract

a invenção refere-se a um injetor descartável compreendendo um alojamento, um êmbolo de acionamento de pistão carregado por mola disposto no dito alojamento e capaz de ser liberado por meio de uma unidade de acionamento, e uma unidade de cilindro e pistão compreendendo um cilindro e um pistão que é posicionado a uma distância do dito êmbolo de acionamento de pistão. uma camada fechada (140) feita de um material elasticamente deformável cerca o êmbolo de acionamento de pistão em pelo menos algumas seções e projeta além das mesmas na direção de acionamento. o objetivo da invenção é projetar um injetor descartável de modo que o paciente não seja alarmado durante o uso do mesmo.
