As the weather gets colder, protect your gear from the elements

The t:slim® Insulin Pump is the only pump with a temperature sensor that will warn you if the pump has been exposed to extreme temperature that may compromise the insulin in the cartridge. If your t:slim Insulin Pump detects a temperature outside of the normal operating range, the TEMPERATURE ALARM occurs and all insulin deliveries are stopped. You can read more about this feature on page 130 of the User Guide. The outdoor adventure crew at Connected in Motion has a few general suggestions that you can use, which may help keep your insulin safe when you are out in the cold this winter:

  • Keep your pump close to your body when it is cold outside. Often, this means against your skin, under clothing, or in the inside pocket of a winter coat.
  • Don’t forget about your tubing! The insulin inside the tubing is susceptible to freezing, so be sure it also stays warm, by keeping it close to your body, under clothing.
  • Vials of insulin for insulin pump cartridge refills should also be kept within the recommended temperature range. When insulin freezes and then thaws, it may be ineffective. (Plus, insulin that is frozen solid is really hard to get out of the vial!)
  • Blood-glucose meters have normal operating temperature ranges too. Outside of this range they often won’t give any reading at all. Meters can be kept in waist belts such as SPIbelts and worn close to the body, under clothing.
  • Equipment that drops below the normal operating range can be warmed up quickly against skin.

As a reminder, avoid exposure of your t:slim Insulin Pump to temperatures below 40° F (5° C), as insulin solutions can freeze at low temperatures.
