Read on to find answers to your questions about our insulin pumps, alerts and alarms as well as important safety information.
Low glucose suspend feature^ (when used in conjunction with Continuous Glucose Monitoring (CGM)) is a feature to help if you want additional protection against hypoglycaemia or hypoglycaemia unawareness. If the feature is turned on, the pump automatically suspends insulin infusion for 2 hours when glucose levels reach a pre-determined threshold and, without intervention, will resume basal insulin delivery to its pre-set rate. All other sensor functions remain operational during insulin suspension.
^ Components sold separately.
If you DO NOT respond to the alarm, the pump suspends insulin delivery, sounds a siren alarm and displays “I have diabetes, call for emergency assistance.” The pump suspends insulin delivery for 2 hours. After 2 hours, the pump resumes basal insulin delivery. If blood glucose (BG) is still low 4 hours after resuming basal, insulin delivery re-suspends.
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 low glucose suspend feature is triggered the pump sirens to ensure the alarm is heard and acted upon.
The two-hour period is based on clinical evidence and allows blood glucose to return to normal. The 4-hour period for resuming insulin delivery after halting it reduces the risk of rebound hyperglycaemia.
SmartGuard™ is a new low glucose suspend feature designed to help people who may have a fear of hypoglycaemia or hypoglycaemia unawareness. It has two different settings so that the pump can automatically ‘Suspend Insulin’ delivery. This suspension of insulin delivery can be set for when the glucose levels are predicted to hit the low limit in the next 30 minutes or can be set to when the glucose levels hit the low limit. The pump can automatically suspend insulin infusion for a maximum of 2 hours when sensor glucose (SG) levels are predicted to approach a pre-determined threshold and, without intervention, will resume basal insulin delivery to its pre-set rate. All other sensor functions remain operational during insulin suspension.
The low glucose features allow you to set your pump to alert, to suspend insulin, or alert and suspend insulin if you are either approaching your low Sensor Glucose limit, or you have reached your low Sensor Glucose limit.
The following table describes the low glucose alert settings.
|How it works|
|Suspend before low||
Your pump temporarily stops delivering insulin if it is predicted that your Sensor Glucose reading will be approaching the low limit within 30 minutes.
Turning on suspend before low, automatically turns on alert on low.
|Alert before low||Your system alerts you any time it is predicted that your Sensor Glucose reading will reach the low limit within 30 minutes. The alert before low can be used whether suspend before low is turned off or on.|
|Suspend on low||
Your pump temporarily stops delivering insulin when your sensor glucose value falls to or below the pre-set low limit.
Turning on suspend on low, automatically turns on alert on low.
|Alert on low||Your system alerts you when your Sensor Glucose reading reaches or falls below your low limit. This is not an optional alert.|
When your pump suspends insulin due to ‘Suspend before low’ the message ‘Sensor glucose approaching Low Limit. Check BG.’ is displayed on your Homescreen.
If you DO NOT respond to the alert, the pump will suspend insulin delivery, sounds a siren alarm and displays “I have diabetes, call for emergency assistance.” The pump basal rate will resume in three ways:
If you DO respond to the alert, you can choose to suspend or resume basal insulin delivery.

When properly assembled with the reservoir and tubing inserted, your MiniMed® 640G insulin pump is waterproof (watertight rating IPX8) at a depth of up to 3.6 metres for up to 24 hours. Because the pump is waterproof, it’s unlikely that water damage will occur if it’s splashed or submerged. However, you should carefully inspect your pump to ensure there are no cracks before exposing it to water, especially if your pump has been dropped or you suspect your pump is damaged. The pump is not waterproof when it is cracked.
If you believe water has entered your pump or you observe any other possible pump malfunction, check your blood glucose, and treat blood glucose per your healthcare professional as necessary. You should always contact your healthcare professional if you experience excessively high or low blood glucose levels, or if you have any questions about your care. Regarding the pump, contact Medtronic for further assistance. 1800 777 808.
You can continue to use your MiniMed® Veo™ insulin pump as normal during your flight. Before travelling outside of Australia, check the compatibility of the radio frequency (RF) used by the pump with existing regulations in your country of destination.
International standards and U.S. Federal Communications Commission (FCC) regulations require that devices using radio frequency capabilities should not be used on an aircraft. Therefore you must disconnect the MiniLink™ transmitter from the glucose sensor. Note that it is not sufficient to turn off the CGM feature because the MiniLink transmitter will continue to transmit on the RF unless disconnected from the glucose sensor. If you need to test your glucose levels while in flight, you will need to do this manually using your blood glucose (BG) meter.
You can continue to use the MiniMed® 640G insulin pump as normal during your flight. Before traveling outside of the European Union, check the compatibility of the radio frequency (RF) used by the pump with existing regulations your destination country.
If you are using the CGM function 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. Therefore you must disconnect the GuardianLink transmitter from the glucose sensor. Note that it is not sufficient to turn off the CGM feature because the GuardianLink transmitter will continue to transmit on the RF unless disconnected from the glucose sensor. If you need to test your glucose levels while in flight, you will need to do this manually using your BG meter.
You should avoid exposing insulin infusion pumps to strong magnetic fields such as those associated with MRI machines. Extensive testing has shown that other magnetised devices such as airport metal detectors, electronic article surveillance equipment, and mobile phones will not affect the working of your insulin pump. Although mobile phones, cordless phones and other wireless high frequency devices can interfere with communication from your glucose monitor/transmitter to your insulin pump, this interference does not cause faulty data and does not damage your pump or the meter. Communication can be restored by removing or switching off these wireless devices.
Your pump should not go through the x-ray machine that is used for carry-on or checked luggage, or the full body scanner. If you choose to go through the full body scanner, you will need to disconnect the infusion set and remove your insulin pump and CGM (sensor and transmitter) prior to the scan. To avoid removing your devices, you should request an alternative screening process that does not use x-ray. Your insulin pump, infusion set, reservoir and CGM system can withstand exposure to airport metal detectors and wands used at airport security checkpoints.
Your pump can make good blood glucose control easier when you travel. You can adjust boluses for meals that come at odd hours, for ones that are bigger or smaller than usual, or for meals that you want to take your time over. You can also adjust your pump to changes in your normal activity level, like sleeping in later.
How you prepare for your travel and what you need to take depends on where you are going and for how long. You’ll obviously need different supplies for a long-haul flight over different time zones, compared to a short domestic holiday.
Here’s a handy checklist:
There is no 'universal' approach when it comes to adjusting basal rates for crossing time zones. When planning a trip, consult with your diabetes healthcare team to discuss the trip itinerary and any adjustments you may need. Don’t forget to always carry a list of your basal rates and other pump settings with you.
Set your pump to the new destination time at any point during your flight or when you arrive. It’s very important, however, that you do change the time to that of your destination, as your basal rate settings may be quite different overnight to during the day. If you don’t change the time, you may receive too much insulin during the daytime and then not enough at night. This can be quite dangerous. Remember to change your time back when you return to your original time zone.
It’s a good idea to get up and walk during long-haul flights and drink plenty of water – this helps prevent blood clotting, which is an issue people with or without diabetes may experience. Blood glucose levels can go too high or low due to stress or changes in activity or eating, so you should test your blood glucose more often.
In the US, doctors’ letters are no longer sufficient proof of medical necessity when you are carrying syringes. In order to board an airplane with syringes and other insulin delivery devices, you must produce an insulin vial with a professional, pharmaceutical, pre-printed label that clearly identifies the medication. No exceptions will be made. If the prescription is located on the outside of the insulin box then you should carry that as well.
Check-in time in the US even for domestic flights is 2 hours to enable you to clear all the security checks.
In the US you must notify security screeners that you have diabetes and that you are wearing a pump and are carrying supplies with you.
An MRI test uses extremely powerful magnetic fields and radio frequency waves to create images of organs and structures inside the body. These strong magnetic fields can damage your pump and potentially pull it from your body. The cannula infusion sets (which do not contain metal) include the Mio, Sof-set, Quick-set and Silhouette, and may be left in your body without concern.
Before having an MRI, X-ray, CT scan or diathermy treatment or other type of exposure to radiation, you should temporarily disconnect your pump, transmitter and glucose sensor before entering the room in which the procedure is to occur.
If you have questions regarding a specific test and how it may affect your pump please contact our global local Helpline 1800 77 808.

It’s not about having the most expensive cover – just one that suits your needs, so check that insulin pump therapy is included. You can log on to: www.privatehealth.gov.au to compare health funds and if in doubt, check with your health fund that your policy meets your needs.
The National Diabetes Service Scheme (NDSS) offers consumable medical products at a subsidised rate for those with an Australian Medicare card and a formal diagnosis of Type 1 diabetes by their medical specialist. For people with Type 1 diabetes, insulin syringes are free. Insulin pump consumables (IPCs) and blood testing strips are subsidised equating to a cost of about $26 per month. The cost of consumables for people with Type 2 diabetes is not covered by the NDSS and costs approximately $270 per month. See http://www.ndss.com.au/en/About-NDSS/Product-and-Supply/ for more details.
It is important to always change your level of health cover to reflect changes in circumstance. Remember, children can be covered on family policies until their late teens or early 20s depending on the policy.
Waiting periods apply to your ability to access many aspects of private health insurance coverage. If you’re in the interim ‘waiting period’ for private health cover benefits, Medtronic hosts a ‘Bridging the Gap’ loan pump program meaning you can go on insulin pump technology straight away. Information on this program is available by speaking with a Diabetes Educator or Medtronic Australasia.
Under the Private Health Insurance Act 2007, private health insurers are required to pay benefits towards devices that are listed on the Prostheses List when provided as part of an episode of hospital treatment, for which a member has an appropriate level of hospital cover and has met any requirements by their individual health fund, e.g. waiting periods. The MiniMed® 640G Insulin Pump is listed on the Prostheses List. Diagnosis of diabetes may follow a hospital admission or GP/specialist consultation, when a hospital admission is not required. Many health funds approve funding for an insulin pump in an ‘outpatient’ setting.
Health fund policies vary, however our commitment is always to ensuring the health of people using Medtronic therapies. If a person’s pump malfunctions ‘out of warranty’, the Medtronic Helpline (which is available 24/7 by calling 1800 777 808) will seek to determine the cause of the malfunction. A ‘product observation report’ can then be provided as evidence the pump is not working (assuming a malfunction) to a patient for their healthcare team. Medtronic will provide short-term loan pumps in this instance to ensure continuity of care while the patient waits for their health fund to approve provision of a new pump.
Dependent on the health fund, “extras” cover may include rebates for a self glucose monitoring device. However, this does not include the cost of consumables or sensors. Some health funds also cover the cost of services provided by a credentialed diabetes educator under their “ancillary” cover. Please check with your health insurance provider for details.
Transmitters and sensors for the Medtronic Insulin Pump System can be purchased directly from Medtronic. A rebate may be provided for the transmitter under ancillary or general (‘extras’) health insurance, depending on your level of cover. Please contact Medtronic Diabetes support services or your health fund for more information. For more information about the benefits you are entitled to under your policy, contact your private health insurer.
The Private Health Insurance Ombudsman provides an independent service to help with health insurance problems and inquiries. You can contact the Ombudsman on 1800 640 695 (free call anywhere in Australia) or email at firstname.lastname@example.org
