1. A method of using a mobile drug infusion device, the method comprising:
determining a time point at which the drug infusion device switches from an inactive mode to an active mode as a use start time point, wherein the drug infusion device includes a housing coupled to a skin of the user with a base body, a refillable insulin reservoir with a predetermined medication dosage sufficient for a predetermined dispensing period, a needle assembly, a storage portion, a driver, and a trigger member and wherein power is provided to at least one component in the active mode and removed in the inactive mode;
providing an impending expiration notification indicating that expiration of the period of use of the drug infusion device is imminent at a first time point after a certain period from the use start time point, based on a usable period of the medication or the material in contact with the medication and a user set time of the drug infusion device; and
providing an expiration notification indicating that the period of use of the drug infusion device has expired at a second time point after the usable period from the use start time point; and
applying the drug infusion device to dispense insulin medication;
wherein the method further comprises:
(a) filling the drug infusion device with a first predetermined medication dosage sufficient for a first predetermined dispensing period, wherein the first predetermined dispensing period ends on a first repetitive day of a week selected for ease of remembrance by a user and attaching the device to user skin;
(b) on the first repetitive day, removing from the user skin and refilling the device with a second predetermined medication dosage sufficient for a second predetermined dispensing period, wherein the second dispensing period ends on a second repetitive day of the week for ease of remembrance and attaching the device on the user for use until the second repetitive day; and
(c) repeating steps a and b each week, wherein the device is refilled and installed on a repetitive twice-a-week replacement schedule on the first and second repetitive days of the week and wherein the first and second repetitive days of the week are programmed by the user into a remote controller that communicates with the device such that the user presets the first dispensing period to be no longer than 80 hours and the second dispensing period to be no longer than 90 hours, wherein the remote controller limits the first and second dispensing periods such that the first and second dispensing periods are not longer than the respective 80 and 90 hours.
