摘要：
A dose control mechanism (510, 610) for a syringe includes an arrangement of screw coupling between an outer surface of a plunger (514, 614) and a channel extending longitudinally (520d, 620d) from a liner (520, 620). The coupling screw arrangement includes a screw segment (514b, 614b) and a step guide (520c, 620c) including a variable step screw. Part of the canal extending longitudinally (520d, 620d) to the liner (520, 620),Including one between the step guide (520c, 620c) and the screw segment (514b, 614b),And the plunger (514, 614) includes the other from between the step guide (520c, 620c) and the screw segment (514b, 614b). The plunger (514, 614) resides within the liner (520, 620) with the screw segment (514b, 614b) coupled with the step guide (520c, 620c). A syringe administering exact dose medicinal products (500, 600) includes such a dose control mechanism (510, 610),A cylinder (540, 640),A plunger sealant (536, 636) and a cylinder adapter set (450) with a cylinder tip (452) and a needle (454). The syringe (500, 600) may be a filling syringe at the time of use,A pre -filled syringe or safety syringe with safety features integrated by needle retraction or needle lining,Or a combination of these.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, 614
