Abstract

A monitor system is provided which includes means for measuring blood glucose values and for generating glucose data signals, monitor means coupled to the measuring means and including means for inputting patient data, means for transmitting and receiving data to and from the monitor means, and computing means for receiving glucose data signal in connection with administration treatment for diabetes mellitus.

Claims

1. A method of monitoring a patient having diabetes mellitus with the use of a blood glucose measuring device and a thereto linked monitor apparatus capable of receiving and storing data, and of using the data to generate insulin dosage recommendations, comprising:

(a) inputting initial physician-supplied data into the monitor apparatus;

(b) supplying patient blood specimens at periodic times to the measuring device;

(c) utilizing the measuring device to obtain blood glucose values from the specimens, and to effect automatic input into the monitor apparatus of glucose data representative of the glucose values;

(d) utilizing the monitor apparatus to prompt and receive patient input into the monitor apparatus at periodic regular times of patient data relating to diet, exercise, emotional stress, and symptoms of hypoglycemia and other illness actually experienced by the patient during a preceding time period;

(e) storing in the monitor apparatus the inputted physician, glucose and patient data;

(f) utilizing the monitor apparatus to at times evaluate the data stored therein and to generate recommendations, based upon the evaluation, relative to patient insulin dosage.

2. A method as in claim 1, wherein the symptoms of illness include fever.

3. A method as in claim 1, wherein step (f) includes generating a recommendation relative to a supplemental insulin dosage.

4. A method as in claim 1, wherein the blood glucose measuring device is a reflectance photometer, and step (b) includes utilizing the monitor apparatus to prompt patient preparation of blood specimen test strips used in the photometer.

5. A monitor system adapted for use by a patient afflicted with diabetes mellitus, comprising:

means for measuring blood glucose values and for generating blood glucose data in response to measuring said blood glucose values;

monitor means, connected to said measuring means and capable of receiving, storing and evaluating data, for (a) receiving and storing said blood glucose data, (b) receiving and storing physician-supplied data, (c) prompting and receiving patient input into the monitor means at periodic times of patient data relating to diet, exercise, emotional stress and symptoms of hypoglycemia and other illness experienced by the patient during a preceding time period, (d) receiving and storing the patient data supplied by the patient, and (e) generating recommendations relative to patient insulin dosage based at least in part upon the received blood glucose data, physician data and patient data.

6. The monitor system as set forth in claim 5 wherein said measuring means includes:

reflectance photometer means for measuring blood glucose values; and

circuit means coupled to said reflectance photometer means for converting the output signals from said reflectance photometer means to glucose data.

7. The monitor system as set forth in claim 5 wherein the recommendations generated by said monitor means include a base insulin adjustment recommendation based at least in part upon said glucose data and said patient data stored in said monitor means over a prescribed number of days.

8. The monitor system as set forth in claim 5 wherein the recommendations generated by said monitor means include a supplemental insulin dose recommendation based at least in part upon said patient data and said glucose data stored in said monitor means.

9. The monitor system as set forth in claim 5 and further comprising:

computer means for at desired times receiving glucose data and patient data from said monitor means and for transmitting a physician insulin prescription to said monitor means;

and communication linkage means for at said times establishing a communication linkage between said computer means and said monitor means.

10. The monitor system as set forth in claim 9 wherein said linkage means includes modems associated with said monitor means and said computer means for receiving and transmitting data therebetween.
