    摘要： Disclosed is a method for initializing an ambulatory infusion system. The method includes providing a liquid drug cartridge (5), the liquid drug cartridge (5) including a cartridge body (51) and a cartridge piston (52), the cartridge piston (52) being arranged inside the cartridge body in a sealing and displaceable manner. The method further includes providing a dosing unit (3), the dosing unit (3) including a metering pump unit (30) with a dosing cylinder (300) and a dosing piston (302), the dosing piston (302) being arranged inside the dosing cylinder (300) in a sealing and displaceable manner, the dosing unit (3) further including a valve unit (31) with a filling port (310) and a draining port (311), the valve unit (31) being configured for switching between a filling state and an alternative draining state, wherein the filling port (310) is fluidic coupled with an inner volume of the dosing cylinder (300) in the filling state and the draining port is fluidic coupled with the inner volume of the dosing cylinder (300) in the draining state . The method further includes providing an initialization force member (61). The method further includes executing a sequence of
    a) exerting, with the initialization force member (61), an initialization pushing force onto the cartridge piston (52), thereby displacing the cartridge piston (52) inside the cartridge body in a cartridge piston advancement direction (X) by an initialization distance;
    b) increasing a fluidic volume of the dosing cylinder (300) by displacing the dosing piston (302), thereby sucking liquid drug out of the liquid drug cartridge (5) into the dosing cylinder (300) and further displacing the cartridge piston (52) inside the cartridge body (51) in the cartridge piston advancement direction (X), without the initialization pushing force being exerted.

    摘要： Disclosed is an analyte measurement kit (1), with:
    a) a sensor assembly (100), the sensor assembly (100) including a transcutaneous sensor element (110) and a control unit (120); the control unit (120) including a battery (121) for powering the sensor assembly (100) and a magnetic sensor (122) designed to generate an electrical activation signal in dependence of a magnetic field, wherein the control unit (120) is designed to switch from a pre-operative state into an operative state upon generation of the activation signal;
    b) an insertion device (200), wherein the insertion device (200) and the sensor assembly (100) comprise complementary coupling structures (130, 230) for releasable coupling; wherein the insertion device (200) is designed for executing an insertion routine, the insertion routine including advancing the sensor assembly (100) from a retracted position where the transcutaneous sensor element (100) stands back behind a skin contact surface (220) of the insertion device (200) into an advanced position where the sensor element (100) projects beyond the skin contact surface (220), and subsequently decoupling the insertion device (200) from the sensor assembly (100).
    The insertion device (200) includes an activation magnet (240) and executing the insertion routine is associated with a change of a magnetic coupling between the activation magnet (240) and the sensor assembly (100), thereby generating the activation signal.
