A glucose sensor is a tiny electrode that measures your glucose levels. It sits under the skin in your interstitial fluid. Glucose sensors are easily inserted using an automatic insertion device: a needle is used to insert the glucose sensor. The needle is then removed leaving just the tiny flexible electrode under the skin. The glucose sensor is then connected to a transmitter so that readings can be transmitted to your insulin pump.
Using glucose sensors does not replace the need for fingerstick measurements. You still need to use your blood glucose meter to confirm a Continuous Glucose Monitoring (CGM) reading before treating or to calibrate the CGM system.
The Enlite™ glucose sensor can be worn for up to 6 days at a time and the Guardian Sensor (3) up to 7 days. The expiration date is on the outside of the glucose sensor box and on each individual glucose sensor package.
The transmitter has a self-contained battery, which can be recharged using the charger supplied, but cannot be changed. As it has a selfcontained battery, the transmitter should be disposed of, or recycled, in accordance with local governing ordinances and recycling guidelines.
The transmitter comes with a 12-month warranty.
No. Glucose sensor should be stored at room temperature. Glucose sensors must not be frozen.
This can depend on what you’re wearing, your desired comfort level, individual preference or experience. While many people choose the abdominal area, some people prefer the upper buttocks, as this location is less likely to be bumped or affected by clothing at the waistline.
The Enlite sensor can be worn on the Abdomen and buttocks however the Guardian Sensor (3) can be worn on the abdomen and buttocks in persons aged 7 to 13, and on the abdomen and arm by persons aged 14 and older. 1
