Abstract

Particularly for diabetes therapy, it is desirable to continuously infuse insulin in varying installments into the body of the patient. A control device serves as a program transmitter for a microdosing unit. The physician should be able to pre-program the daily profile of the infusion and, if necessary, to change it. According to the disclosure, at least the control device for the microdosing unit has memory means for a prescribable control program allocated to it, whereby the control program is pre-programmable in discrete time steps by an external programming device corresponding with a 24 hour daily sequence. The control device is detachably connected directly with the programming device or is coupled therewith by means of a program carrier or a programmed memory chip solely for a rapid transfer of the pre-programmed control program into the internal memory means of the control device. Thus the control device is particularly adapted for the adjustment of diabetes patients to an optimum daily profile of insulin administration outside of a hospital setting.
