REDUNDANT INJECTION DEVICE STATUS INDICATION
First Claim
1. A device for delivering a drug from a reservoir comprising:
- a housing with a space shaped to hold the reservoir;
said housing defining an optical path from outside the device to an interior of the reservoir such that a payload status of the reservoir can be discerned from a vantage point outside the device;
a generator of a coded light signal, said generator positioned so that at least a portion of said coded light signal travels along said optical path and is viewable from said vantage point.

Abstract
A method and system for a drug delivery device with multiple status indicators is disclosed. For example the device may include an operator indicator and/or second indicator. The indicators may be seen in one location. For example they may be viewed through one optical path. Optionally the operator indicator may attract attention. The operator indicator may give information that is pertinent to operation of the device to an operator of the system. The operator indicator may have an encoded output signal. Optionally a second indicator may convey information that is not conveyed by the user operator by the operator indicator, for example information that is not pertinent to the regular operation of the machine. Alternatively or additional, the second indicator may function at times when operator indicator is not functioning.

18. A device for delivering a drug from a reservoir comprising:
-
a drug reservoir including a transparent portion through which an interior of the reservoir is visible such that a payload status of the reservoir can be discerned from a vantage point outside the device; a generator of a coded light signal, said generator positioned so that at least a portion of said coded light signal overlaps said transparent portion from said vantage point.

19. A method of indicating a status of a system for delivering a drug the system including a housing and a reservoir for said drug, the method comprising:
-
exposing an internal portion of said reservoir a vantage point outside the housing via an optical path; generating a coded light signal; indicating a status of the device with said coded light signal transmitting said coded light signal along said optical path to said vantage point. - View Dependent Claims (20, 21, 22)
