Abstract
A computer implemented method of determining a clinical variables utilizing an insulin pump that includes initiating blood glucose measurements, initiating ingestion of carbohydrates and receiving input data based on the blood glucose measurements and the ingestion of carbohydrates and utilizing the data to calculate clinical variables. The invention may include presenting instructions to a patient to take various actions and to input various data. The clinical variables determined may be stored in memory and then used to calculate insulin doses and to send a signal to an insulin pump to infuse the insulin dose calculated.
Claims19
A computer-implemented method of determining a carbohydrate factor utilizing an ambulatory infusion pump, the method comprising:
- receiving input data related to a first blood glucose measurement;
- presenting instructions to ingest a quantity of carbohydrates;
- receiving an input indicating the quantity of carbohydrates ingested;
- waiting a length of time;
- receiving input data related to a second blood glucose measurement;
- calculating a change in blood glucose between the first blood glucose measurement and the second blood glucose measurement;
- calculating a carbohydrate factor by dividing the change in blood glucose by the quantity of carbohydrates ingested;
- saving the carbohydrate factor in memory;
- receiving input as to a quantity of carbohydrates to be ingested at a meal;
- utilizing the carbohydrate factor in memory to calculate an insulin dose to be infused prior to the meal;
- and
- sending a signal to an infusion device controller to infuse the insulin dose.
A computer implemented method of determining an insulin sensitivity factor utilizing an insulin pump, the method comprising:
- receiving input data related to a first blood glucose measurement;
- initiating an infusion of a known preselected quantity of insulin;
- recording a time of the infusion of the known quantity of insulin;
- waiting a length of time;
- receiving input data related to a second blood glucose measurement;
- calculating a change in blood glucose between the first blood glucose measurement and the second blood glucose measurement;
- calculating an insulin sensitivity factor by dividing the change in blood glucose by the quantity of insulin infused;
- saving the insulin sensitivity factor in memory;
- receiving input of a current blood glucose level and target blood glucose level;
- utilizing the insulin sensitivity factor to calculate an insulin dose to be infused;
- sending a signal to an infusion device controller to infuse the insulin dose.
