1. A fluid infusion device for delivering a medication fluid to a body, the fluid infusion device comprising:
- a housing that receives a fluid cartridge module comprising an electrically conductive element;
an electronic detection circuit having electrically conductive terminals;
a fluid pump mechanism within the housing;
a drive motor coupled to actuate the fluid pump mechanism;
a transcutaneous conduit assembly comprising a fluid conduit in fluid communication with the fluid pump mechanism;
an insertion mechanism for inserting the fluid conduit into the body; and
a processor device operatively coupled to the drive motor, wherein the processor device executes computer readable program instructions to initiate an automatic startup routine when the fluid cartridge module is initially installed in the housing, in response to contact between the electrically conductive element of the fluid cartridge module and the electrically conductive terminals of the electronic detection circuit;
wherein the insertion mechanism is automatically activated to insert the fluid conduit into the body when the fluid cartridge module is initially installed in the housing.

Abstract
A fluid infusion device and related operating methods are disclosed. The fluid infusion device has a housing, a fluid pump mechanism, a transcutaneous conduit assembly having a fluid conduit coupled to the pump mechanism, and an insertion mechanism for inserting the conduit into the body. An exemplary method begins by detecting a first installation of a fluid cartridge module in the housing, wherein the detecting occurs after the housing has been affixed to the body. In response to the detecting, the operating method automatically activates the insertion mechanism to insert the fluid conduit into the body.
