Abstract
Abstract Method for intravenous feeding of a patient by a pump and a pump actuator which is provided with readily insertable and removable cams which control the number of pump strokes per unit of time and also the amount of intravenous fluid injected by each stroke in accordance with a prescription of intravenous fluid placed in a container. A predetermined prescription of intravenous fluid is prepared and placed in a container. The container and a cam which is tailored to the requirements of the prescription in the container is delivered to the patient. The cam is placed on the pump actuator. The container is connected to the pump and the pump is connected to a vein of the patient. The pump actuator is operated by the use of the cam to operate the pump to supply the prescribed intravenous liquid in the container to the patient in accordance with the prescription.
