Abstract

Método y aparato asociado con la retraccion segura de agujas médicas de su uso. Se revelan modalidades para combinaciones comprendiendo jeringas médicas y sistemas de agujas auto retráctiles (10). Un mecanismo almacenador de energía, retractor de agujas comprende un tubo elástico (180) que también es pensado para realizar una pluralidad de funciones comprendiendo el almacenamiento de fuerza por la cual una aguja médica (140) es retraída, sellos deslizables (150), válvulas normalmente cerradas (160) y control de volumen dinámico por el que se evita la rejurgitacion de fluido por la retraccion de la aguja. Un control selectivo, constrictivo del volumen interno del tubo (180) cuando se estrecha inhibe efectivamente el flujo rejurgitacion de la aguja (140). En todas las modalidades, la retraccion de la aguja se inicia por fuerzas aplicadas en una direccion transversal a lo largo del eje de la aguja (140) usando solamente una mano. La jeringa (10) puede usarse en una pluralidad de modos tales como una jeringa estándar o una aguja prellenada. También se revelan métodos para la manufactura y ensamble. La manufactura de la invencion requiere solamente de un método para la manufactura y ensamble. La manufactura de la invencion requiere solamente de un numero y complejidad de partes mínimas tales que un costo de manufactura proyectado es potencialmente lo suficientemente bajo para ser competitivo en costo con las combinaciones contemporáneas de jeringas hipodérmicas y sistemas de agujas no retráctiles.
