Abstract

aperfeiçoamento introduzido em seringa hipodérmica de segurança, sendo que a presente seringa compreende um corpo principal (1), que apresenta um formato cilíndrico e que em seu extremo posterior apresenta duas atas radialmente opostas (2), ao passo que o extremo frontal do referido corpo (1) inclui um estreitamento (3), local onde é internamente montada uma peça postiça (4) que configura o terminal onde a agulha é montada; internamente, o estreitamento (3) incorpora nervuras de travamento (5) que servem como meio de retenção para a parede externa (6) da peça postiça (4); a haste do êmbolo (7) é formada por quatro paredes radiais contrapostas (8), sendo que a presente seringa prevê que a haste do êmbolo (7) seja definida como urna estrutura, que na sua região frontal, incorpora uma linha de enfraquecimento (9) que separa a porção traseira (7a) da haste do êmbolo da sua porção frontal (7b), onde está montada a guarnição de borracha (10); a região frontal (7b) da haste do êmbolo (7b), apresenta um terminal troncocônico (7c), o qual, na sua região central conta com uma projeção de retenção (7d), a qual é fornada por um curto trecho anelar (7d1), que tem continuidade em uma projeção troncônica (7d2).improvement introduced in a safety hypodermic syringe, the present syringe comprising a main body (1), which has a cylindrical shape and which at its posterior end has two radially opposite legs (2), while the front end of said body (1) includes a neck (3), where an insert (4) is internally mounted that configures the terminal where the needle is mounted; internally, the narrowing (3) incorporates locking ribs (5) that serve as a retaining means for the outer wall (6) of the insert (4); the piston rod (7) is formed by four opposed radial walls (8), and the present syringe provides that the piston rod (7) is defined as a structure, which in its frontal region incorporates a weakening line ( 9) separating the rear portion (7a) of the piston rod from its front portion (7b), where the rubber gasket (10) is mounted; the frontal region (7b) of the piston rod (7b) has a frustoconical terminal (7c), which, in its central region, has a retention projection (7d), which is formed by a short annular section (7d1 ), which continues in a frustoconical projection (7d2).
