A fluid infusion device and related operating methods are disclosed. The fluid infusion device has a housing, a fluid pump mechanism having an inlet and an outlet, a first flow path in fluid communication with the inlet and at least partially defined by structure compatible with fluid cartridge modules containing medication fluid, a second flow path in fluid communication with the outlet and terminating at a subcutaneous conduit for a body, and a drive motor that actuates the pump mechanism. An exemplary operating method detects a first installation of a fluid cartridge module in the housing. The detecting occurs after the housing has been affixed to the body and after the subcutaneous conduit has been inserted into the body. In response to the detecting, the operating method initiates an automatic priming operation to prepare the device for delivery of the medication fluid to the body.

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 containing the medication fluid;a fluid pump mechanism within the housing, the fluid pump mechanism comprising an inlet and an outlet;a first flow path in fluid communication with the inlet and at least partially defined by structure compatible with the fluid cartridge module;a second flow path in fluid communication with the outlet, the second flow path terminating at a subcutaneous conduit for the body;a drive motor enclosed within the housing and coupled to actuate the fluid pump mechanism; anda processor device operatively coupled to the drive motor, wherein the processor device executes computer readable program instructions to initiate an automatic priming operation when the fluid cartridge module is initially installed in the housing, wherein the automatic priming operation controls activation of the drive motor to actuate the fluid pump mechanism by a predetermined amount that corresponds to a designated number of pump cycles of the fluid pump mechanism. 2. The fluid infusion device of claim 1, wherein the automatic priming operation primes the first flow path, the fluid pump mechanism, and the second flow path with the medication fluid to prepare the fluid infusion device for delivery of the medication fluid to the body. 3. The fluid infusion device of claim 1, wherein the predetermined amount is calibrated in accordance with a combined fluid volume of the first flow path, the fluid pump mechanism, and the second flow path. 4. The fluid infusion device of claim 1, wherein: the fluid cartridge module comprises coded features; andthe program instructions executed by the processor device interpret the coded features and automatically configure at least one operating parameter of the fluid infusion device in accordance with the coded features as interpreted. 5. The fluid infusion device of claim 1, wherein: the fluid cartridge module comprises a first structural feature that cooperates with a second structural feature of the fluid infusion device; andthe processor device initiates the automatic priming operation in response to interaction between the first structural feature and the second structural feature. 6. The fluid infusion device of claim 1, wherein: the fluid cartridge module comprises an electrically conductive element;the fluid infusion device comprises an electronic detection circuit having electrically conductive terminals; andthe processor device initiates the automatic priming operation in response to contact between the electrically conductive element and the electrically conductive terminals. 7. The fluid infusion device of claim 1, further comprising a sensor system enclosed within the housing, wherein the sensor system detects when the fluid cartridge module is initially installed in the housing. 8. The fluid infusion device of claim 1, wherein: the fluid infusion device is a disposable insulin pump device; andthe medication fluid comprises insulin. 9. A method of operating a fluid infusion device comprising a housing that receives fluid cartridge modules containing medication fluid, a fluid pump mechanism within the housing and having an inlet and an outlet, a first flow path in fluid communication with the inlet and at least partially defined by structure compatible with the fluid cartridge modules containing medication fluid, a second flow path in fluid communication with the outlet and terminating at a subcutaneous conduit for a body, and a drive motor enclosed within the housing and coupled to actuate the fluid pump mechanism, and a processor device operatively coupled to the drive motor, wherein the processor device executed computer readable program instructions to initiate an automatic priming operation, the method comprising: 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 and after the subcutaneous conduit has been inserted into the body; andin response to the detecting, initiating an automatic priming operation to prepare the fluid infusion device for delivery of the medication fluid to the body, wherein the automatic priming operation controls activation of the drive motor to actuate the fluid pump mechanism by a predetermined amount that corresponds to a designated number of pump cycles of the fluid pump mechanism. 10. The method of claim 9, wherein the automatic priming operation primes the first flow path, the fluid pump mechanism, and the second flow path with the medication fluid contained in the fluid cartridge module. 11. The method of claim 9, wherein the predetermined amount is calibrated in accordance with a combined fluid volume of the first flow path, the fluid pump mechanism, and the second flow path. 12. The method of claim 9, wherein: the fluid cartridge module comprises a first structural feature that cooperates with a second structural feature of the fluid infusion device; andthe detecting is associated with interaction between the first structural feature and the second structural feature. 13. The method of claim 9, wherein: the fluid cartridge module comprises an electrically conductive element;the fluid infusion device comprises an electronic detection circuit having electrically conductive terminals; andthe detecting is associated with contact between the electrically conductive element and the electrically conductive terminals.
