Abstract

Particularly for diabetes therapy, it is desirable to continuously infuse insulin in different rates into the body of the patient, because the insulin requirements of the diabetic are subject to great fluctuations. Therefore, a control device serves as the program transmitter for a microdosing unit. The control device for the microdosing unit has memory means for a prescribable control program allocated to it, whereby the control program can be called up directly by the patient at the control device. The program sequence of the infusion is started only by means of the dialing-up of a plurality of insulin units to be delivered into the body or of relevant food values taken in by the patient with a meal and of a starting time (T.sub.1, T.sub.2). In addition, specific base rates of the infusion can be selected by the patient. With the invention device, diabetes patients can call up the necessary insulin administration according to short programs at meals.
