Insulin pumps
Please note: Insulin requirements may change over time, in particular during pregnancy and in adolescence. Therefore, you are encouraged to discuss this decision with your health care professional.
We have designed the 7series insulin pump for patients who use more insulin or anticipate using more insulin - specifically, more than 50 units daily. The 7series insulin pump can hold up to 300 units of insulin; it can also use either of the 2 MiniMed Paradigm reservoirs -- the 1.76 ml (MMT-326A) or the 3.0 ml reservoir (MMT-332A). Therefore, if you are anticipating life changes such as pregnancy or adolescence, you may appreciate the flexibility to upsize or downsize your reservoir. If you currently use more than 50 units daily, you may want to consider the MiniMed Paradigm Veo 754 for its larger reservoir capacity.
The 5series insulin pump can accommodate our 1.76 ml reservoir, and it holds up to 176 units of insulin. It is ideal for people who require less than 50 units of insulin per day. In addition, it is the best choice for people who want the maximum discretion offered by the smaller, lighter-weight member of the Paradigm insulin pump family (the MiniMed Paradigm Veo 554).
Medtronic are the only Company on the market offering this flexibility of different model sizes to suit the different requirements patients may have.
The insulin pump is IPX-7, which means that it is protected against water immersion for 30 minutes at a depth of 1 meter. So while it is designed to survive only any accidental dunking or splashing, it is not designed to be swum with. You should temporarily disconnect the pump while bathing or swimming.
Alarms
If you are using the CGM funstion of your pump then you can set high/low glucose alerts, predictive high/low glucose alerts, rate of change alerts and Snooze alerts for any of these alarms. You can also turn on the Low Glucose Suspend feature.
The Paradigm® Veo™ has more alerts and alarms than any other product on the market, but these can all be customised and can be turned on or off depending on your needs.
The high and low glucose alarms have to be at least 0.6 mmol/L apart. If you set your high glucose limit at 5.6 mmol/L, then you cannot set your low glucose limit greater than 4.9 mmol/L. Conversely, if you set your low glucose limit at 2.8 mmol/L then you cannot set your high limit lower than 3.3 mmol/L.
For example, you can change your high and low alarm thresholds to levels that are appropriate for you. In addition, you can disable the "high glucose" alarm when you know you are going high. Another example is to adjust the time duration of the "snooze alarm" so that you receive fewer reminders. Other alerts can be avoided by taking action before they occur, such as doing your calibration on a regular schedule and keeping your transmitter within 6 feet (2 meters) of the insulin pump so that synchronisation is not lost.
If the feature is turned on, the pump automatically suspends insulin infusion for 2hours when glucose levels reach a pre-determined threshold and, without patient intervention, will resume Basal insulin delivery to it’s pre-set rate.
All other sensor functions remain operational during insulin suspension
LGS is a safety feature, rather like an airbag in a car, helping to protect you and providing peace of mind for you, your parent/carer and healthcare professional. It is designed to reduce the severity of hypoglycaemic episodes, NOT to prevent hypoglycaemia itself.
If you DO respond to the alarm, you can choose to suspend or resume Basal insulin delivery. If you resume Basal delivery then your pump will continue to deliver insulin. If you choose to suspend, the pump suspends insulin delivery as above.
When the LGS is triggered the pump will siren to ensure the alarm is heard and acted upon.
A CAL ERROR happens when a meter reading vastly differs from a CGM reading. There are 3 main reasons this can happen:
- If you have an inaccurate meter reading, a long delay between taking your fingerstick and entering your meter value into the CGM system, or if you use more than 1 blood glucose meter to calibrate
- If you calibrated when your glucose is changing rapidly - such as after a meal
- If there is something wrong with the sensor
If the new meter reading is still really different from the CGM reading and the system displays a second CAL-ERROR message followed by a "SENSOR END" message, then you will need to replace the sensor.
Calibration
The MiniMed Paradigm® Veo™ System must be calibrated a minimum of twice a day (once every 12 hours) by entering a fingerstick value into the insulin pump. However for best results, you can calibrate 3 to 4 times per day, with the calibrations spread throughout the day at periods when glucose is not changing rapidly, this will allow more accurate detection at all levels.
It is important to calibrate when glucose values are not changing rapidly (for example glucose is more stable before a meal. After a meal, it is more likely that glucose will change rapidly to adjust for the food being digested).
Glucose sensors
The glucose sensor measures glucose levels in your body's interstitial fluid (fluid between the cells). It does not infuse insulin, nor does the measurement automatically cause the insulin pump to infuse a certain amount of insulin. Insulin is administered through the cannula or needle of an infusion set connected to the inmsulin pump.
Note - infusion sets should be inserted at least 5 cm away from the glucose sensor site.
Our latest sensors do not need to be refrigerated if kept at temperatures ranging from 2˚ to 27˚ C (or 36˚ to 80˚ F). This temperature labeling applies to all manufactured glucose sensors over the last year. To identify these glucose sensors, look for a temperature graphic on the outside of the individual glucose sensor package, or on the side of the glucose sensor box. Glucose sensors are still being shipped in a protective foam container containing chilled gel packs designed to protect glucose sensors from temperature outside of the 2˚ to 27˚ C range during shipment.
Glucose sensors must not be frozen.
If you choose to keep your sensors in the refrigerator anyway, allow approximately 15 minutes for the sensor to warm up to room temperature before you use it.
Glucose sensors have a 6 month expiration date from the time they are manufactured. An expiration date will appear on the outside of the glucose sensor box and on each individual glucose sensor package.
Note - glucose sensors used for the iPro system should only be worn for up to 3 days at a time.
Sensor readings may never actually quite reach the apexed highs or lows of your blood sugar due to the lag time between blood glucose and sensor glucose. i.e. the blood sugar may have reached a high and then quickly begin to fall and the sensor glucose will be following this in relation to the calibration factor applied to it and thus begin to fall with the blood sugar in order to track as closely as possible to blood sugar readings.
Other
The Bayer Contour Link meters and MiniLink transmitter send information to the insulin pump using radio frequency. So if other devices that use radio frequency are in use, such as mobile phones, cordless phones or wireless networks, they may prevent communication between the insulin pump and the meter. This interference will not cause incorrect data to be sent and will not cause any harm to your insulin pump or meter so moving away from or turning off these other devices may help.
If you are using the CGM funstion of the pump, International standards and U.S. Federal Communications Commission (FCC) regulations require that devices using radio frequency capabilities should not be used on an aircraft. So you must disconnect the MiniLink transmitter from the glucose sensor. It is not sufficient to simply turn the continuous glucose monitoring (CGM) feature off on the insulin pump because the MiniLink transmitter will continue to transmit on the RF frequency and will only stop if disconnected from the glucose sensor. While in flight, you need to manually test your glucose levels using your BG meter.
Note - when downloading data and reviewing historical reports, you will notice "data gap" where information is missing during this period of time.
