Abstract

Se describe un mecanismo de control de dosis 10 para una jeringa que incluye un émbolo 14 que tiene un tornillo de paso burdo 14B sobre su superficie exterior, un alojamiento 20 que tiene una guía de paso burdo correspondiente 20C a lo largo de la superficie interior del alojamiento 20, un tornillo 30 que tiene un roscado de paso fino 30B que se interconecta con una tuerca de paso fino 18B de un adaptador 18, en donde el émbolo 14 tiene un espacio anular interno 14C dentro del cual el tornillo 30 reside por lo menos parcialmente. Una jeringa de administración de fármaco de dosis exacta incluye tal mecanismo de control de dosis 10, un barril 140, un sello del émbolo 136 y un conjunto de adaptador de barril 150 que tiene una punta de barril 152 y una aguja 154. La jeringa puede ser una jeringa de llenado al tiempo del uso 100, una jeringa prellena 200 o una jeringa de seguridad 300 que tiene elementos de retracción de aguja o elementos de envoltura de aguja integrados o una combinación de los mismos. Similarmente se revelan métodos de ensamble, métodos de manufactura y métodos de operación.
