Infusion pump with temperature monitoring
View Patent ↗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.
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.
