The reservoir contains the fluid, and the drive system forces the fluid from the reservoir. The electrical elements control the pow er to the drive system to regulate the rate that fluid is forced from the reservoir. The tab mates with the housing, and contains at least one electrical element. The tab is removable, and may be replaced with a differe nt tab. The different tab may change the rate fluid is forced from the reservoi r. A tab may be removed from one external infusion device and installed in a different external infusion device. The tab may be limited to use in a predetermined number of external infusion devices and may include a power supply.
