Abstract

uma nova seringa de segurança com autotravamento e autodestrutiva. a presente invenção refere-se a uma nova seringa de segurança com autotravamento e autodestrutiva, que compreende um cilindro oco, um êmbolo que desliza pelo cilindro, um plugue de borracha na frente do êmbolo e um assento para a agulha na parte frontal do cilindro. o êmbolo é provido de uma plataforma circular, que é provida de um dente flexível que se estende obliquamente em direção à parede interna do cilindro. o cilindro é provido na extremidade de uma porção de diâmetro aumentado. na posição transitória entre a porção de diâmetro normal e a porção com diâmetro aumentado do cilindro, fica posicionado um degrau inclinado, sob o qual existe uma ranhura que pode prender o dente flexível quando o êmbolo é movido para trás. a porção do cilindro com diâmetro aumentado é provida internamente de um grampo circular que pode pressionar contra o fundo da plataforma circular. para uma seringa com a estrutura acima mencionada, o êmbolo pode ser travado depois da injeção da seguinte forma: o êmbolo é provido de um dente flexível que se estende em direção à parede interna do cilindro: o dente flexível fica preso na ranhura quando o êmbolo é puxado para trás; o degrau inclinado acima do dente flexível evita que o êmbolo seja movido para frente; e, sob a ação da ranhura, o dente flexível também não pode se mover radialmente.
