Abstract
An infusion apparatus incorporates a RAM which has a first storage section for storing only one delivery pattern defining an infusion rate and a volume to be infused at the infusion rate, and a PDP storage section for storing a plurality of delivery patterns. In a one-pattern delivery mode, an infusion fluid is delivered according to the only one delivery pattern read out from the first storage section by a CPU. Therefore, infusion is performed at the same rate from the beginning to the end. In a PDP (Program Delivery Profile) mode, an infusion fluid is delivered according to the plurality of delivery patterns read out in sequence from the PDP storage section. Therefore, infusion is performed at various rates. One of the one-pattern delivery mode and the PDP mode is selected by an operator through operation of a mode selector in consideration of factors such as the kind of medication and the condition of the patient.
