摘要： The present invention relates to an infusion pump system of fluid which can keep supplying a regular quantity of the fluid to the patient regardless of the position of the reservoir by applying pressure upon the reservoir. The infusion pump system of fluid according to the present invention comprises a flexible reservoir containing the fluid therein; a chamber having a squeezer therein which is in tight contact with an outer surface of the reservoir to apply pressure on the reservoir and spaced from an inner wall of the chamber; a storage containing air therein to be supplied to a space between the inner wall of the chamber and the squeezer; and a pressurizing plate movable back and forth in the storage by driving force of a motor to supply the air in the storage to the space between the inner wall of the chamber and the squeezer.
