Abstract
The invention concerns an array and a method for dosing a hormone regulating the blood glucose, especially insulin, of a diabetic patient. In order to improve the administration of the hormone, the invention provides the following characteristic combination: a first sensor for measuring tissue glucose level; a controller having as an input the measured tissue glucose level from the first sensor, the controller having a control algorithm to determine an amount of hormone to be dosed based upon the measured tissue glucose level; a hormone dosing unit connected to the controller and automatically administering a hormone dose based upon a signal received from the controller; a second sensor for measuring an influencing patient variable; a pilot control device connected to the second sensor, the pilot control device connected to and forming a circuit with the controller, the pilot control device acting on the controller in accordance with the influencing patient variable that is measured by the second sensor, whereby the pilot control device reduces dead time of the controller.
