Abstract: An apparatus for the biofeedback control of body functions is proposed having at least one sensor for detecting biological body functions, a data memory for storing comparison values, a control unit or microprocessor (9, 16) and a therapy member, the control means (9, 16) activating the therapy system as a function of the measured values detected by the sensor and the comparison values. The therapy systems has a pump for the intravenous, intra-arterial, oral or intraluminal administration and a drug reservoir connected to the pump. The control unit and/or therapy means is provided with a memory, which stores the therapy objectives for the body functions with associated drug doses as a function of the detected measured values and comparison values.
