Abstract

L'invention concerne une pompe électrique à pression pour ballons, qui est associée à un instrument médical. La pompe à pression électrique pour ballons comprend : un moteur (3), une tige de poussée (5) comportant un filetage externe ; un manchon de tige de poussée (7) ; et un dispositif de commande, comportant un filetage interne. Une extrémité de la tige de poussée est montée à demeure sur le moteur, et l'autre extrémité de la tige de poussée est une extrémité libre et s'étend dans le manchon de tige de poussée. Le dispositif de commande comportant un filetage interne est monté à demeure sur le manchon de tige de poussée. La tige de poussée et le dispositif de commande comportant un filetage interne forment une adaptation reliée en spirale. Le moteur entraîne la tige de poussée, de telle sorte que la tige de poussée peut se déplacer vers l'avant et vers l'arrière dans le manchon de tige de poussée le long de la direction axiale du manchon de tige de poussée. En fonction de la pompe, pendant la mise sous pression, la mise sous pression est effectuée à l'aide du moteur, permettant ainsi une économie de main d'œuvre et une efficacité élevée. Pendant la détente de la pression, l'adaptation rotative de la tige de poussée est supprimée à l'aide d'un dispositif de détente de pression, ce qui permet à la tige de poussée de se déplacer directement vers l'arrière. Par la commande du fonctionnement du moteur, une mise sous pression linéaire, une mise sous pression de courbe secondaire et une mise sous pression segmentée peuvent être effectuées, et des données peuvent être stockées, partagées et revérifiées.
