Patent ID: 8221359

Claim:
A drug delivery device, comprising: a housing having a battery compartment and proximal and distal ends; the proximal end includes: an operator selection panel, a display panel that displays the operator selections, and an electronic circuit, powered by the battery, which receives the operator selections as displayed on the display panel and outputs a control signal to a driver motor; the distal end includes: a drug reservoir, and a removable injection needle that are operatively connected to the drive motor and a cover detector; a removable cover that encloses the distal end and overlies the cover detector when assembled on the housing, wherein the electronic circuit further comprises: a set-up mode when the cover is overlying the cover detector, and a dose injection mode when the cover detector is uncovered and an injection option is operated, wherein the operator selection panel used to set the size of a dose to be injected when in the dose injection mode, and the operator selection panel used to set a number of parameters on the display panel when in the set-up mode are at least partly the same, and wherein when the electronic circuit is in set-up mode it allows the display panel to indicate different operator selections, which operator selections are not available on the display panel in dose injection mode.
