Method for controlling body fluid condition using diuretics, based on weight measurement
First Claim
Patent Images
1. 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 programcalculates a difference between a target weightand 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.

Abstract
The system for controlling body fluids overcomes the limitations of the prior art by automatically infusing diuretic and/or other drugs into a human patient. In one approach, the rate of infusion of the diuretic is adjusted based on the measured weight of the patient. For example, this weight can be transmitted wirelessly to a portable diuretic infusion device attached to the patient.

18. 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 a 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 infusion rate of the diuretic when the measured weight is different from the target weight;
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 when 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;
displaying the calculated infusion rate to the patient; andinfusing the diuretic subcutaneously into the human body at the infusion rate determined by the program. - View Dependent Claims (19, 20)
