Abstract

Un conjunto de jeringa que comprende: un cilindro (120) que incluye una pared lateral cilíndrica (110) que tiene una superficie interior (126) que define una cámara (128) para la retención de fluido, un extremo proximal abierto (129) y un extremo distal (121) que incluye una pared distal (122) que tiene una abertura a través de ella en comunicación de fluidos con dicha cámara (128), dicha pared lateral (110) incluye una nervadura (123) adyacente a dicho extremo proximal (129) y una rampa (127) que tiene una longitud axial que se extiende desde la nervadura (123) hacia dicho extremo proximal (129) de tal manera que el diámetro del cilindro (120) aumenta a lo largo de la rampa (127) desde la nervadura (123) hacia el extremo proximal (129); un vástago alargado (140) de émbolo que incluye un extremo proximal (149), un extremo distal (141) y un cuerpo principal (148) que se extiende entre el extremo proximal y el distal, el vástago (140) de émbolo es movible distal y proximalmente dentro de dicha cámara (128), el extremo proximal (149) incluye un apoyo-de-pulgar (142), el extremo distal (141) incluye una parte (146) de acoplamiento de tapón, y el vástago (140) de émbolo incluye además al menos una parte frangible (143) que comprende una conexión frangible estrechada dispuesta en un extremo proximal (149) del vástago (140) de émbolo; el tapón (160) tiene un extremo proximal (169) y un extremo distal (161), el tapón (160) está conectado a la parte (146) de acoplamiento de tapón del vástago (140) de émbolo, caracterizado por que, el vástago (140) de émbolo incluye además un saliente flexible (144) entre el apoyo-de-pulgar (142) y el cuerpo principal (148), el saliente (144) tiene un diámetro mayor que el diámetro del cilindro (120) en la nervadura (123) y el tapón (160) es movible distal y proximalmente con respecto a la parte (146) de acoplamiento de tapón una distancia axial preseleccionada de tal manera que cuando el extremo distal (161) del tapón (160) está en contacto con la pared distal (122) del cilindro (120), se permite al saliente (144) avanzar distalmente pasando la nervadura (123) del cilindro (120) y trabar el vástago (140) de émbolo en el cilindro (120), la parte (146) de acoplamiento de tapón comprende un expositor visual que es totalmente visible antes de que se aplique una fuerza inicial dirigida distalmente al vástago (140) de émbolo y el expositor visual es bloqueado después de que se aplique la fuerza dirigida distalmente al vástago (140) de émbolo para mover la parte (146) de acoplamiento de tapón del vástago (140) de émbolo distalmente la distancia axial preseleccionada.
