Integrated drug infusion device

An integrated drug infusion device, comprising:

• an infusion unit configured to deliver drugs;
• a program unit comprising an input end and an output end, and the input end comprising a plurality of electrically connective regions for receiving a signal of analyte data in a body fluid, after the output end is electrically connected to the infusion unit, wherein according to the signal of the analyte data in the body fluid, the program unit controls whether the infusion unit delivers the drugs;
• an infusion cannula with a conductive area, the infusion cannula is a drug infusion channel;
• and
• a plurality of electrodes for detecting the analyte data in the body fluid, the plurality of electrodes comprising a conductive-area electrode and a cannula-wall electrode, the conductive area of the infusion cannula forms the conductive-area electrode, and the cannula-wall electrode being located on/in a wall of the infusion cannula, wherein the integrated drug infusion device further comprises a mounting unit and a housing, the mounting unit is configured for holding the infusion cannula in a pre-installation position, the mounting unit is configured to move relative to the housing to move the infusion cannula from the pre-installation position to a working position,
• wherein the mounting unit is configured such that when the mounting unit moves the infusion cannula from the pre-installation position to the working position, the infusion cannula is inserted into skin, the infusion cannula connects with the infusion unit such that the drugs are capable of being injected into a body through the infusion cannula, and the plurality of electrodes electrically connects the plurality of electrically connective regions respectively to input the signal of the analyte data in the body fluid to the program unit.
