Abstract

A drug delivery device capable of working in at least two different modes which includes a dose injection mode and a set-up mode. The drug delivery device automatically changes from the dose injection mode to the set-up mode and vice versa in accordance with the detection of the cover by a cover detection switch. In the dose injection mode doses can be set and injected; in the set-up mode various parameters assisting the use of the drug delivery device can be set. This setting is preferably done by selecting the parameters from a menu, also in this mode historical data stored in the device can be viewed.

Claims

1. 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.

2. A drug delivery device as in claim 1, wherein a number of parameters can be set in the set-up mode, the parameters including one or more of the following parameters:

languages of use

date and time

insulin type

maximum dose size

maximum daily quantity

alarm functions.

3. A drug delivery device as in claim 1, wherein historical data stored can be viewed in the set-up mode.

4. A drug delivery device as in claim 1, wherein the operator selection panel includes a dose setting option, an escape option, an accept option, and the injection option.

5. A drug delivery device as in claim 1, wherein the operator selection panel includes multiple separate dedicated buttons.
