Method and apparatus for the control and regulation of glycemia
First Claim
1. A control and regulation system for continuously monitoring glycemia for a diabetic patient, comprising, in combination, means for continuously withdrawing and sampling a low flux of the blood of the diabetic patient, measuring means for continuously determining the glucose concentration in said flux, electronic regulation means for determining the difference between the concentration thus determined and the normal concentration and for determining the quantity of product capable of adjusting the glucose concentration to the normal concentration;
- means for injecting the diabetic patient with a suitable amount of glucose or insulin to produce said normal concentration, the amount of such injection being controlled by said electronic regulation means, and being a function of said difference.

Abstract
The invention relates to the control and regulation of glycemia (that is the glucose rate in blood) for diabetic patients. The device comprises means for sampling the total blood of a diabetic patient 2, means 9 for determining the glycemia of the blood, an electronic unit 11 providing, as a function of the indications at 9, the operation of pumps 15 apable of injecting insulin or 16 capable of injecting glucose. There are also provided recording means for the glycemia 14 and a sound alarm.

5. A method for controlling blood glucose levels comprising the steps of:
-
(1) withdrawing and continuously sampling a low flux of blood from the diabetic patient, (2) continuously measuring the glucose concentration in said flux, (3) electronically determining the difference between said glucose concentration and the normal glucose concentration for determining the quantity of glucose or insulin necessary to adjust the glucose concentration to the normal concentration, and (4) injecting the diabetic patient with a suitable quantity of glucose or insulin determined by said electronic comparison, said quantity being a function of said difference. - View Dependent Claims (6)
