Ambulant apparatus and method for operation of a syringe for parenteral infusion with the volume of the syringe dependent.

摘要

A syringe-pushing device for ambulant treatment automatically delivers, in a constant time compatible with circadian rhytms, a fixed number of boluses of a volume which varies according to the contents of the syringe (9) used by the operator. Said volume is generally equal to the daily dose of the medicament and can be read directly from the graduations (11) on the syringe (10). An acoustic warning signal indicates obstruction of the flow of fluid and inadvertent non-scheduled injection of boluses.
