Abstract
This invention relates to a syringe-pusher device for ambulatory treatment, automatically delivering in a constant time compatible with the circadian rhythms, a fixed number of elementary volumes varying as a function of the prior filling volume of the syringe used by the operator. Said volume generally corresponding to the daily dose of drug can be directly read on the graduations on the syringe. A sound alarm is set off in the event of an impediment to the flow of the fluid as well as in the event of the untimely injection of elementary volume outside the set program.
