Abstract

La présente invention concerne une pompe (2) pour solution chimique, par exemple de l'insuline La pompe (2) comprenden piston (12) déplaçable le long d'un axe, une unité d'entraînement qui presse le piston (12) avec une force d'entraînement prédéterminée pour déplacer le piston (12) dans une première direction le long de l'axe, et un mécanisme d'ajustement (23) qui ajuste le mouvement, du piston (12) de sorte que l'unité fonctionnelle se déplace avec la force d'entraînement Le mécanisme d'ajustement (23) applique une force auxiliaire au piston (12) dans une direction identique à la première direction, ou applique une force de réaction au piston (12) dans une seconde direction opposée à la première direction, conformément à la différence entre une force de résistance générée par le mouvement du piston (12) et la force d'entraînement L'invention concerne également un dispositif d'administration de solution chimique (1) comprenant une telle pompe (2)
