1. A portable infusion pump system, comprising:
- a pump device including a pump housing that defines a space to receive a medicine, a drive system positioned in the pump housing to dispense the medicine from the pump device when the medicine is received in the space of the pump housing, wherein the pump housing houses at least one electrically conductive element of a drive system detector that is mounted to a component of the drive system;
a controller device removably attachable to the pump housing so as to electrically connect with the pump device, wherein the controller device houses control circuitry configured to communicate with the drive system positioned in the pump housing to control dispensation of the medicine from the pump device,wherein the control circuitry of the controller device is configured to disable the drive system in response to the drive system detector indicating damage to one or more components of the drive system,wherein the electrically conductive element of the drive system detector is mounted to a piston rod of the drive system and is in electrical communication with the control circuitry that includes computer-readable instructions stored on a computer-readable medium housed in the controller device that, when executed by a processor of the control circuitry, measures an electrical characteristic of the electrically conductive element mounted to the piston rod, and wherein the drive system detector shifts indicates damage to one or more components of the drive system when the electrical characteristic is substantially greater than zero.
