A programmable infusion system includes a disposable IV tubing apparatus for conveying intravenous fluid from a source to a patient. A compact, portable case has a receptacle for removably receiving a segment of the disposable apparatus. A peristaltic pump is mounted in the case for engaging the segment of the disposable apparatus and pumping intravenous fluid therethrough. A motor is mounted in the case and is connected for driving the pump upon energization thereof. A bar code reader is mounted in an edge portion of the case for sensing a bar code label attached to the source of intravenous fluid, such as a bag. The bar code label represents the prescribed fluid delivery parameters. These are read and displayed in alphanumeric form by the system when the edge portion of the case containing the bar code reader is passed over the label. A micro-controller mounted in the case energizes the motor so that the peristaltic pump conveys the fluid through the disposable apparatus in accordance with the delivery rate parameters.
