Abstract

This document discusses, among other things, an apparatus comprising a pump configured to deliver a fluid from a cartridge, a display a temperature sensor and a controller. The controller is configured to compare a temperature within the cartridge as measured by the temperature sensor to a threshold temperature and cause the display to display a message relating to temperature when the measured temperature goes beyond the threshold temperature.

Claims

1. An ambulatory infusion pump system, comprising:

a pump;

a cartridge adapted to contain a fluid, where the pump is configured to receive the cartridge and cooperate with the cartridge to deliver fluid from the cartridge to a patient;

a display;

a temperature sensor adapted to determine a temperature within the cartridge when the cartridge is coupled to the pump; and

a controller communicatively coupled to the temperature sensor and the display, the controller adapted to;

compare the temperature to a threshold temperature, including both an extreme heat threshold and an extreme cold threshold defining a stable operating range for the fluid there between; and

cause the display to display a message indicating that the fluid has been exposed to an extreme high temperature if the temperature exceeds the extreme heat threshold and cause the display to display a message indicating that the fluid has been exposed to an extreme low temperature if the temperature is below the extreme cold threshold.

2. The ambulatory infusion pump system of claim 1, wherein the temperature sensor is automatically put into communication with the cartridge when the cartridge is coupled to the pump device.

3. The ambulatory infusion pump system of claim 1, wherein the temperature sensor is disposed within the pump.

4. The ambulatory infusion pump system of claim 1, wherein the fluid is insulin.

5. An ambulatory infusion pump system, comprising:

a pump;

a cartridge adapted to contain a fluid, where the pump is configured to receive the cartridge and cooperate with the cartridge to deliver fluid from the cartridge to a patient;

a display;

a temperature sensor adapted to determine a temperature within the cartridge when the cartridge is coupled to the pump; and

a controller communicatively coupled to the temperature sensor and the display, the controller adapted to;

determine from the temperature that stability of the fluid in the cartridge may have been affected based on occurrence of an extreme temperature; and

display a warning on the display that the fluid has been exposed to an extreme temperature.

6. The ambulatory infusion pump system of claim 5, wherein the temperature sensor is automatically put into communication with the cartridge when the cartridge is coupled to the pump device.

7. The ambulatory infusion pump system of claim 5, wherein the temperature sensor is disposed within the pump.

8. The ambulatory infusion pump system of claim 5, wherein the fluid is insulin.

9. A method comprising:

providing an ambulatory infusion pump system, the system including a pump, a cartridge adapted to contain a fluid, wherein the pump is configured to receive the cartridge and cooperate with the cartridge to deliver fluid from the cartridge to a patient, a display, a temperature sensor adapted to determine a temperature within the cartridge when the cartridge is coupled to the pump and a controller communicatively coupled to the temperature sensor and the display;

automatically monitoring a temperature of the cartridge while the cartridge is coupled to the pump device with the temperature sensor;

comparing the temperature to a threshold temperature with the controller, including both an extreme heat threshold and an extreme cold threshold defining a stable operating range for the fluid there between; and

upon the controller determining that the temperature exceeds the extreme heat threshold or is below the extreme cold threshold display a message on a user interface indicating that the fluid has been exposed to an extreme high temperature or an extreme low temperature.

10. The method of claim 9, wherein the temperature sensor is automatically put into communication with the cartridge when the cartridge is coupled to the pump.

11. The method of claim 9, wherein the temperature sensor is disposed within the pump.

12. The method of claim 9, wherein the fluid is insulin.
