Abstract An infusion device with a disposable administration set which is inexpensive to manufacture. In the preferred embodiment of the present invention the disposable administration set has a plurality of elongated cam followers connected to a plate assembly, wherein the cam followers are displaced in a predetermined sequence and forced against a delivery tube by cam means driven by rotary drive means. The disposable administration set is injection molded as a single integral piece. The disposable administration set includes adjustment spacers disposed between the plate assembly and the cam followers which adjust the distance between them to keep the device accurate. In the preferred embodiment of the present invention the cam means are configured to provide fluid delivery at a consistent and uniform rate.
A method of automatically programming a small, portable pump or cooperation with a disposable administration set comprising: inserting, by relative motion, said disposable administration set within said pump; simultaneously, automatically, transferring coded data regarding a prescribed infusion profile from said administration set to said pump, using said relative motion of said disposable administration set and said pump to automatically activate said transferring; In response to said transferring step, automatically storing said data in said pump; and automatically varying the pumping rate of said pump in accordance with said coded data regarding a prescribed infusion profile stored in said pump.
