1. A method for providing for the insulin needs of a diabetic individual, comprising:
- mounting a blood flow sensor on the individual such that digestive tract blood flow may be monitored;
monitoring said digestive tract blood flow and forming an electrical data signal relating thereto;
computing the individual insulin needs based upon said electrical data signal; and
delivering an amount of insulin responsive to said determined need to the individual.

Abstract
A method and apparatus for providing for the insulin needs of a diabetic individual utilizes blood flow in the digestive tract as the operative variable. Such blood flow is monitored and when deviations from a base level are sensed insulin is provided in measured amounts. The blood flow may be monitored on a continuous basis to provide real-time analysis and delivery. The system may be under microprocessor control, and may include recording means to allow a record of blood flow and insulin delivery to be made either for insulin need computation or for later review.

5. A method for providing of the insulin needs of an individual, comprising:
- mounting a blood flow sensor on the individual such that digestive tract blood flow may be monitored;
monitoring said digestive tract blood flow and forming a data signal embodying such blood flow data at a first time;
computing the individual'"'"'s insulin needs based upon said blood flow data;
delivering an amount of insulin responsive to said computed insulin need;
storing said blood flow and insulin amount in memory means;
sampling said digestive tract blood flow at a second time;
recalculating said individual'"'"'s insulin needs based upon said second time blood flow data and said stored blood flow and insulin amount data; and
storing said recalculated insulin amount and second time blood flow data in system memory.

6. Apparatus for administering insulin to a patient in accordance with the patient'"'"'s requirements, comprising a blood flow sensor located upon the patient to sense digestive tract blood flow;
- control means operatively connected to said flow sensor to calculate the insulin need of the patient based upon data received from said flow sensor; and
insulin dispensing means operatively connected to said control means to administer the amount of insulin calculated by said control means. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15, 16)
