Microprocessor-controlled device for administering - or sampling - liquid products as well as microcurrents. It consists of a frame 1 whose upper part 2 is removable and contains a syringe 3 fitted with a needle 4. An electronic microcircuit 5 controls the operation of an electric motor 7 which actuates a rack 8 which ensures penetration and retraction of the needle 4, and an electric motor 9 which drives a rack 10 actuating the piston 11. Potentiometers 12, 13, 14, 27 and 32 respectively program the power and duration of operation of the motor 9, the synchronisation of the motors 7 and 9, the sensitivity threshold of an electronic circuit sensitive to variations in conductivity 24 at the tip of the needle 4, as well as the intensity of a current generated by a second electronic circuit 31. The device according to the innovation is intended particularly for the practice of mesotherapy. <IMAGE>
