Abstract

um mecanismo de controle de dose (510, 610) para uma seringa inclui um arranjo de rosca de parafuso de engate entre uma superfície exterior de um êmbolo (514, 614) e um canal se estendendo longitudinalmente (520d, 620d) de um invólucro (520, 620). o arranjo de rosca de parafuso de engate inclui um segmento de rosca (514b, 614b) e uma guia de passo (520c, 620c) incluindo uma rosca de passo variável. parte do canal se estendendo longitudinalmente (520d, 620d) do invólucro (520, 620), incluindo um de entre a guia de passo (520c, 620c) e o segmento de rosca (514b, 614b), e o êmbolo (514, 614) inclui o outro de entre a guia de passo (520c, 620c) e o segmento de rosca (514b, 614b). o êmbolo (514, 614) reside dentro do invólucro (520, 620) com o segmento de rosca (514b, 614b) engatado com a guia de passo (520c, 620c). uma seringa de administração de medicamentos de dose exata (500, 600) inclui um tal mecanismo de controle de dose (510, 610), um cilindro (540, 640), um vedante de êmbolo (536, 636) e um conjunto adaptador de cilindro (450) com uma ponta de cilindro (452) e uma agulha (454). a seringa (500, 600) pode ser uma seringa de enchimento no momento da utilização, uma seringa pré-cheia ou uma seringa de segurança com características de segurança integradas por retração de agulha ou por revestimento de agulha, ou uma combinação destas.
