Abstract:
1. A device for regulating the concentration of glucose in the blood of a diabetes patient, the device comprising: a measuring component adapted for measuring the concentration of glucose in the blood of the diabetes patient; a pump component adapted for selectively introducing glucagon into a body of the patient or introducing glucose into the bloodstream of the patient, or introducing insulin into the body of the patient via at least one hypodermic needle to be inserted into the body of the patient; and a control component which receives signals from the measuring component which are representative of said concentration, and which controls the pump component on the basis of at least one reference value for said concentration pre-entered into the control component and a program such that said concentration is regulated, wherein the program incorporates an adjustable glucagon injection curve represented by a formula 1 (ml(E)/fall mmol/l/unit of time) and an adjustable insulin injection curve represented by formula 2 (ml(E)/rise mmol/l/unit of time) corresponding to an amount of glucagon or insulin, respectively introduced into the body of the patient, and the nominal concentration of the glucose in the blood of the patient as a reaction thereto, wherein the device is embodied such that the measuring component and the pump component can be in substantially permanent contact with a bodily fluid or the blood of a patient.
