Abstract
An infusion syringe pump for forcing an infusion liquid out of the syringe comprises a sensor which is actuated at a certain displacement of a movable piston in the syringe. The residual infusion time before the syringe is completely empty is calculated from the residual volume of liquid left in the infusion syringe upon activation of the sensor, and from the infusion rate. At a given time before expiration of the residual infusion time, an alarm is produced by an alarm device. The alarm is thus always given independently of the particular infusion rate of the syringe and at a predetermined time (e.g. three minutes) before the end of infusion.
