Abstract
La presente invención se refiere a un medio mejorado para ajuste de la dosis de líquido a ser inyectado de una jeringa que tiene un alojamiento para recibir un recipiente con líquido, donde el recipiente con líquido tiene un primer extremo cerrado y un pistón que cierra un segundo extremo del recipiente, el alojamiento tiene un extremo próximo y un extremo distal, el extremo distal está adaptado para recibir un montaje con aguja de inyección para permitir el paso del líquido fuera del primer extremo del recipiente, una barra de émbolo recibida dentro del alojamiento para ejercer una fuerza en el pistón que cierra el segundo extremo del recipiente, donde la mejora comprende: un primer medio dentro del alojamiento para prevenir la rotación de la barra de émbolo en relación al alojamiento, un segundo medio que, consiste de un medio de punta, que encaja una primer superficie de la barra de émbolo para restringir el movimiento de la barra de émbolo hacia el extremo próximo del alojamiento, un tercer medio que encaja una segunda superficie de la barra de émbolo para el movimiento calibrado con respecto a la barra de émbolo y el alojamiento hacia el extremo próximo del alojamiento, y un cuarto medio fijado con respecto al alojamiento para parar cualquier movimiento del tercer medio hacia el extremo distal del alojamiento en una posición fijada relativa al alojamiento.The present invention relates to an improved means for adjusting the dose of liquid to be injected from a syringe having a housing for receiving a container with liquid, where the container with liquid has a first closed end and a piston that closes a second end of the container, the housing has a proximal end and a distal end, the distal end is adapted to receive an injection needle mount to allow fluid to pass outside the first end of the container, a plunger rod received within the housing to exert a force on the piston that closes the second end of the container, where the improvement comprises: a first means inside the housing to prevent rotation of the piston rod in relation to the housing, a second means, which consists of a pointed means , which engages a first surface of the plunger rod to restrict movement of the plunger rod to the proximal end of the housing, a third means engaging a second surface of the plunger rod for calibrated movement with respect to the plunger rod and the housing towards the proximal end of the housing, and a fourth means fixed with respect to the housing to stop any movement from the third means to the distal end of the housing in a fixed position relative to the housing.
