Abstract

Se describe una protección pasiva de seguridad de anillo de enganche para uso con dispositivos médicos de inyección. La protección de seguridad comprende un manguito interior que define un canal que es dimensionado para recibir un dispositivo de inyección y un manguito exterior que define un canal que es dimensionado para recibir en forma deslizante el manguito interior. Un miembro de desviación es proporcionado entre el manguito interior y el manguito exterior a fin de empujar el manguito exterior con relación al manguito interior de una posición retraída a una posición avanzada. Un anillo elástico de enganche es soportado sobre la protección de seguridad en una posición que evita el movimiento del manguito exterior con relación al manguito interior de la posición retraída a la posición avanzada. El anillo de enganche puede ser deformado en respuesta al accionamiento del dispositivo de inyección para desembragar el manguito exterior del manguito interior y permitir que el miembro de desviación mueva al manguito exterior de la posición retraída a la posición avanzada con relación al manguito interior.
