Abstract

resumo seringa descartável e haste do êmbolo para a mesma diz respeito a uma seringa descartável e uma haste do êmbolo para uso em uma seringa descartável. a haste do êmbolo compreende uma extremidade proximal, uma extremidade distal e um eixo estendendo-se através da extremidade proximal e da extremidade distal. a extremidade distal da haste do êmbolo é dotada de um mecanismo de encaixe rápido e de um flange de retenção localizado do lado proximal do mecanismo de encaixe rápido. o flange de retenção compreende uma porção do corpo principal formada sobre o eixo da haste do êmbolo e uma pluralidade de porções digitiformes estendendo-se a partir da porção do corpo principal em uma direção oposta ao eixo da haste do êmbolo. de acordo com a presente invenção, uma pequena força de impulsão continua sendo aplicada à haste do êmbolo após o término da injeção, obtendo-se desse modo um curso adicional necessário quando a extremidade distal da haste do êmbolo se encaixa no assento de agulha, reduzindo, ao mesmo tempo, a dor do paciente.
