Abstract

This document discusses, among other things, an apparatus comprising a pump configured to deliver insulin, a processor, and a user interface including a bistable display. A display element of the bistable display is placed in one of two stable orientations upon application of a biasing voltage and stays in the stable orientation when the biasing voltage is removed. The processor includes a display module configured to display a non-blank reversion display screen on the bistable display when no input is received at the user interface after a specified time duration, and to recurrently change the reversion display screen until input is received at the user interface.

Claims

1. A medical pump system for administering medicaments to a patient, comprising:

a pump;

a user interface operably coupled to the pump, the user interface including a color display for presenting information in a variety of display colors; and

monitoring means operably coupled to the user interface for monitoring the clinical status of the user, the color display being responsive to the monitoring means such that the color presented by the color display is dependent on, and indicative of, the clinical status of the user.

2. A medical pump system as claimed in claim 1, the display color presented on said color display changing from one color to another in response to a change in the clinical status of the user.

3. A medical pump system as claimed in claim 2, the clinical status of the user including one or more of a recent blood glucose reading, the exercise status of the user, or the user eating within a specified time period, the change in clinical status of the user being one or more of a recent blood glucose reading being higher than a first threshold blood glucose value, a recent blood glucose reading being lower than the same threshold blood glucose value or a second threshold blood glucose value, the user exercising within a specified time period, the user eating within a specified time period, the user not eating within a specified time period, or the user having active insulin in their body.

4. A medical pump system as claimed in claim 1, the display color presented on said color display changing from one color to another in response to a change in the status of the pump.

5. A medical pump system as claimed in claim 4, the pump system further including an insulin cartridge, and a device battery, the change in the status of the pump being one or more of the insulin cartridge containing less than a threshold level of insulin, the device battery having a capacity less than a threshold battery capacity value, or an indication that the pump has stopped operating.

6. A medical pump system as claimed in claim 1, a change in the color of the display screen including one or more of a change in a display backlight color, or a change in a text color, or a color flashing indicator.

7. A medical pump system as claimed in claim 1, the color presented on said color display indication being a gradual change.

8. A medical pump system as claimed in claim 7, the gradual change indicating a gradual decrease of medicament in the body of the patient.
