Patent ID: 8070742

Claim:
A method of automatically infusing diuretic to an ambulatory human patient at home comprising: attaching a diuretic infusion device to the body of the ambulatory human patient; receiving weight information based on body weight measurements performed by the patient to measure his body weight; adjusting an infusion rate of diuretic into the patient based on the received weight information according to a predetermined protocol wherein: a program calculates a difference between a target weight and a measured weight; determines a rate of an initial diuretic infusion; adjusts the rate of diuretic infusion using a diuretic infusion protocol chosen among a plurality of diuretic infusion protocols; and calculates a difference between the target weight and measured weights at different time points within a day; and a controller controls a pump based on one of the measured weight of the patient thereby controlling a rate of infusion of the diuretic according to the program to maintain the target weight by adjusting the rate of diuretic infusion until one of the measured weights reaches near the target weight; wherein the adjustment of the diuretic infusion rate starts after a measured weight information is put into the diuretic infusion device, adjusting the diuretic infusion rate with each of the weight measurements at the different time points, and continues adjusting the infusion rate until one of the measured weight reaches near the target weight; and infusing the diuretic subcutaneously in the human body at the infusion rate determined by the program.
