Interlocking drug infusion device and artificial pancreas

An interlocking drug infusion device, comprising:

• a drug reservoir, used for accommodating a drug to be infused, provided with a piston and a screw;
• a driving wheel, connected with the screw, driving the screw to push the piston forward by rotation;
• a driving unit, the driving unit moved in a driving direction to drive the driving wheel to rotate;
• at least one actuator, electrically connected to the driving unit, used to provide power for the driving unit in the driving direction after energized;
• a program module, electrically connected to the at least one actuator, the program module providing a first driving instruction for controlling the at least one actuator to perform periodic power output;
• and
• a position detection module, used to determine a periodic drug infusion amount, wherein when the periodic drug infusion amount reaches a preset threshold, the position detection module and/or the program module provide the at least one actuator with a second driving instruction,
• wherein the first driving instruction includes energized time T1 and de-energized time T2, and the de-energized time T2 is not less than a shortest time t required for the linear actuator to recover from deformation,
• the second driving instruction includes de-energized time T3, and the de-energized time T3 is not less than a shortest time t required for the linear actuator to recover from deformation.
