Description

COMPUTER-IMPLEMENTED METHOD AND APPARATUS FOR DIABETES MANAGEMENT

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of U.S. Provisional Patent Application No. 60/669,431 filed on April 8, 2005 which is incorporated in its entirety herein by reference.

FIELD OF THE INVENTION

The present invention relates to management of diabetes and more particularly to a method and apparatus for assisting a user with diabetes management.

BACKGROUND

Diabetes Mellitus is a disease known since ancient times. In 1865 Bernard identified that "something" controlled glucose levels in the blood and that diabetes mellitus occurred because that "something" was deficient or missing. Later, insulin was discovered to be that "something" and it was given to people whereby diabetes mellitus became a possibly survivable disease.

Ever since insulin was first given to people, it has been characterized on a molecular level and the physiology of the human glucose-insulin action has been defined. This characterization of molecular and physiologic aspects of human glucose control includes the timing of glucose excursions and of the changes in the relationship between insulin action and glucose responsiveness during a 24-hour day.

As the pathophysiology of diabetes mellitus was studied and better defined, the technology of diabetes management was developed to allow for glucose measurement and insulin delivery to diabetic individuals throughout the day. Current clinical glucose measurement is primarily episodic, with single measurements of blood glucose taken with a finger stick and done by the diabetic individuals or by others.

Avoiding dysglycemia (low and high glucose levels) is vital to the clinical management of diabetes mellitus, and in many patients, current approaches are unsuccessful as measured by the occurrence of acute and chronic complication, and by the immense cost of diabetes care in this country and throughout the world.

Low blood glucose levels are potentially devastating because they can produce coma and lesser degrees of brain dysfunction that can result in injury or death. Low blood glucose levels may be unrecognized by people who have diabetes mellitus for several years, thereby causing an added danger. Furthermore, low blood glucose levels are the major impediment to clinically acceptable glucose level control in insulin dependent, diabetes mellitus patients.

High blood glucose levels are associated with increased risk of devastating long term complications in all people with diabetes mellitus. These complications include microvascular and macrovascular problems. Microvascular complications of diabetes mellitus include retinopathy (visual loss), nephropathy (renal or kidney failure) and neuropathy (loss of feeling, altered sensation, severe pain, or inability to recognize low blood glucose levels). Macrovascular complications of diabetes mellitus include myocardial infarction, increased cardiac death, and stroke. All of these complications are reduced by improved blood glucose control and many are reversible over time if glucose levels are normalized.

Current treatment, based upon episodic, patient obtained, finger stick glucose measurements, are not adequate to obtain clinical diabetes management targets because blood glucose levels can fall by 50% in 20 minutes, or increase by 200% in 15 minutes, depending upon the circumstances. Further, significant changes in glucose levels occur when patients are sleeping.

Diabetes Mellitus makes people's life more complicated. It can be difficult for a person to maintain a useful glucose diary, and it can be challenging to achieve "acceptable" glucose levels.

There is a critical need for people with Diabetes Mellitus to manage their specific glucose levels as well as individual factors that determine dysglycemia in people with diabetes mellitus. Further, there is a need to be able to identify and alert diabetic patients to life events and associated glucose trends that produce recurrent dysglycemia.

WHAT DOES THE USER DO WITH THE DATA FROM THE LIFE EVENT DIARY?

The user of the present invention has now written their own program for more successful management of their diabetes. The user is beginning to get information that they never had before. It is understood that this is just the beginning of collecting data for analysis. The reason is because if the program is used only once, its repetitiveness cannot be relied upon. If the program is used many times, the repetitiveness will enable the user to predict of glucose changes in certain situations. With this information, the user will be able to manage their glucose levels and diabetes more successfully.

Moreover, the data can be shown to a physician or nurse, particularly when discussing your diabetes management with them.

An advantage of the present invention is that it allows the user to rely on their own experiential knowledge intimacy of how their diabetes mellitus reacts to life events and the physiologic responsiveness for better control and successful management.

There is a clinical application of the computerized intensive life event diary programs with mathematical modeling of continuously generated glucose data that anticipates and alerts patients with diabetes mellitus to increased vulnerability to low and high glucose levels.

This system changes the paradigm of treatment in people with diabetes mellitus by making insulin delivery prospective based on the individuals life events and physiologic responsiveness, instead of being generalized or reactive to high or low glucose levels that have already occurred, as it is now.

This system has the potential to improve glucose control over time, thereby improving quality of life and clinical outcomes by avoiding acute and chronic complications of diabetes. Application of this system is designed to avoid the major impediment to effective diabetes control, namely hypoglycemia. By preventing hypoglycemia, this system will also prevent adverse effects from hypoglycemia unawareness as well as rebound hyperglycemia. It can recognize glycemic effects of exercise, sleep, or work in individuals.

This system is designed to prevent hyperglycemia as well. It will recognize meals or mealtimes associated with inadequate insulin use, as well as life events that require increased insulin doses such as emotional stress, pain, menses or arousal.

Although the invention has been shown and described with respect to a certain preferred embodiment or embodiments, certain equivalent alterations and modifications will occur to others skilled in the art upon the reading and understanding of this specification and the annexed drawings. In particular regard to the various functions performed by the above described components (assemblies, devices, etc.) the terms

(including a reference to a "means") used to describe such components are intended to correspond, unless otherwise indicated, to any component which performs the specified function of the described component (i.e., that is functionally equivalent), even though not structurally equivalent to the disclosed structure which performs the function in the herein illustrated exemplary embodiments of the invention.
