A positive displacement intravenous infusion pump device and method are disclosed to precisely meter intravenous fluid to a patient. Intravenous fluid to be injected into the vein of a patient is placed in a closed rigid fluid container, and a variable (but fixed for each administration) quantity of incompressible material, stored in a separate receptacle, is introduced into the fluid container to cause displacement of fluid from the container to thereby inject the fluid into the vein of the patient. Introduction of incompressible material is controlled so that the intravenous fluid is injected in a controlled manner into the vein of the patient.
