1. A control device for infusion apparatus which on the one hand consists of a housing (2, 41, 62) implanted in a patient's body (1, 40, 61) and has a delivery and dosage unit (27) for the measured transportation of infusion liquid from a feed container (28) to the outlet of a catheter (31) together with the assigned operating circuit, and which on the other hand consist of a separate control or programming apparatus (3, 42, 63, 142) for the operating circuit, where for inductive signal transmission the control or programming apparatus (3, 42, 63, 142) possesses a first coil (12, 49, 64, 71, 149) and the operating circuit possesses a second coil (21, 121), and where coding of the signals to be transmitted is provided for in the control or programming apparatus by a coder (9, 46, 68, 146) and by a decoder (25, 53, 74, 153) in the operating circuit, characterized in that by means of the coder/decoder (9/25, 46/53, 68/74, 146/153) either each control signal for adjusting a variable infusion rate of the delivery and dosage unit (27) is individually transmitted with a code signal in accordance with a predetermined code or an entire signal sequence as a control programme for timed infusion rates is trasmitted with a common code signal in accordance with a predetermined code, which control programmes are held in storage means (55, 57, 76, 180) assigned to the operating circuit for the delivery and dosage unit (27). |
