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.

First claim

What is claimed is:

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.

2 . The device of claim 1 , wherein said optical path includes a window within said housing.

3 . The device of claim 1 , further comprising:
a sensor directed toward said space for sensing a status of the reservoir and wherein said generator is responsive to output of said sensor.

4 . The device of claim 1 , further comprising:
a processor receiving a feedback from the device and said processor controlling said generator in accordance to said feedback.

5 . The device of claim 4 , wherein said processor is configured to generate said code for a light signal to indicate that said apparatus is functioning properly.

6 . The device of claim 4 , further comprising:
a sensor located within the housing directed toward said space for sensing a status of the reservoir and feedback includes an output of said sensor.

7 . The device of claim 6 , wherein said sensor includes a position sensor sensing a position of the reservoir.

8 . The device of claim 1 , further comprising:
a position sensor sensing a position of the reservoir and wherein said generator is responsive to output of said sensor.

9 . The device of claim 1 , wherein said portion of an interior of said reservoir and said coded light signal are visible along said optical path simultaneously.

10 . The device of claim 1 , wherein said generator is configured to generate said coded light signal to indicate that said apparatus is functioning properly.

11 . The device of claim 4 , further comprising: a position sensor operationally connected to said processor said sensor sensitive to a position of said reservoir and said feedback includes an output of said position sensor.

12 . The device of claim 1 , wherein said generator is configured for illuminating at least a portion of said reservoir with said coded light.

13 . The device of claim 1 , wherein said generator is configured for illuminating at least a portion of said reservoir with said coded light.

14 . The device of claim 1 , wherein said generator is configured for obscuring at least a portion of said reservoir with said coded light.

15 . The device of claim 1 , further comprising said reservoir at least partially filled with the drug.

16 . The device of claim 1 , wherein said generator generates the coded light signal in between 3 and 6 modes.

17 . The device of claim 1 , where said generator generates the coded light signal with three colors, a constant signal and a blinking signal.

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.

20 . The method of claim 19 , further including:
discharging the drug from said internal portion of said reservoir during delivery of the drug.

21 . The method of claim 19 , further comprising:
illuminating said internal portion of said reservoir with said coded light signal.

22 . The method of claim 19 , further comprising:
reflecting a portion of said coded light signal from said reservoir.
