ABSTRACT:
An infusion pump formed by a fluid containing shell and a pressurizing shell. A conical helical spring is attached within the pressurizing shell. A circular fluid bag with an outlet tube is placed within the fluid containing shell. The bottom of the fluid containing shell is contoured to match the contour of the fluid bag. The fluid containing shell and the pressurizing shell are threadably received within one another so that by screwing the shells together the spring is compressed to pressurize the fluid bag. A platen distributes the force of the spring over a substantially flat area of the bag.
