Abstract

Un mecanismo de control de la dosis (510, 610) para un jeringa que incluye una disposición roscada de roscas enroscadas entre una superficie exterior de un émbolo (514, 614) y un canal que se extiende longitudinalmente (520D,620D) de una carcasa (520, 620). La disposición roscada de roscas enroscadas incluye al menos un segmento roscado (514B, 614B) y una guía de paso (520C, 620C) que incluye una rosca de paso variable. Al menos una parte del canal quese extiende longitudinalmente (520D, 620D) de la carcasa (520, 620) que incluye una de la guía de paso (520C, 620C) y el o los segmentos roscados (514B, 614B), y el émbolo (514, 614)incluye el otro de la guía de paso (520C, 620C) y el o los segmentos roscados (514B, 614B). El émbolo (514, 614) reside, al menos parcialmente, dentro de la carcasa (520, 620) con el o los segmentos roscados (514B, 614B) enroscados con la guía de paso (520C, 620C). Una jeringa de suministro preciso de la dosis de fármacos (500, 600) incluye dicho mecanismo de control de la dosis (510, 610), un cuerpo cilíndrico (540, 640), un cierre hermético del émbolo (536, 636), y un conjunto adaptador del cuerpo cilíndrico (450) que tiene una punta del cuerpo cilíndrico (452) y una aguja (454). La jeringa (500, 600) puede ser una jeringa de llenado en el momento de utilización, una jeringa de llenado previo o una jeringa de seguridad que tiene integrada unas características de retracción de la aguja o de recubrimiento de la aguja, o una combinación de ambas. De manera similar, se exponen métodos de ensamblaje, fabricación y operación.
