Skin patch drug infusion device

A skin patch drug infusion device, comprising:

• an infusion mechanism module, wherein the infusion mechanism module includes:
• a reservoir, used for accommodating a drug to be infused, a screw and a piston connected with the screw, wherein the screw and the piston are arranged inside the reservoir;
• a driving unit, provided with a driving wheel and a driving end, wherein the driving wheel is connected with the screw, and the driving end pushes the driving wheel to make the screw advance in the reservoir;
• a power unit, connected with the driving unit, used for offering power for the driving unit;
• a control mechanism module, electrically connected with the infusion mechanism module to regulate drug infusion;
• a blockage detection module, operably connected to the control mechanism module, including a detection circuit and at least one detection element, used to sense and measure physical parameters during a drug filling process or a drug infusion process to confirm whether a blockage has occurred;
• and
• an adhesive patch, for attaching the infusion mechanism module and the control mechanism module to a skin surface.
