At Medtronic, we are committed to continually evaluating and improving the quality and reliability of our products and services. Through our monitoring system, we have learned about potential issues and we would like to inform you about these and provide recommendations regarding the usage of our pumps.
Sensor Graph Timeout Safety Information for MiniMed Veo Pumps (MMT-554 and MMT-754 only) with sensor usage and Low Glucose Suspend feature enabled
Your MiniMed Veo insulin pump allows you to set the number of minutes to display the Sensor Graph before returning to the home screen.
The factory default setting for Sensor Graph timeout is set to 2 minutes. If the Sensor Graph timeout is set to “NONE” it can prevent the auto-resume of basal delivery 2-hours after a Low Glucose Suspend event, which can result in elevated blood glucose values.
[This will only happen if you go to the Sensor Graph screen during a Low Glucose Suspend event, and leave that screen displayed and if the Sensor Graphic Timeout is set to “NONE”]
When this happens, the pump will beep 3 times every 15 minutes to remind you that insulin delivery has been suspended. All other alarms will function normally, but basal delivery will not resume as long as the Sensor Graph screen is displayed.
You can find the insulin pump model in the status screen or on the label on the back of the insulin pump.
This feature allows you to select how long the Sensor Graph screen will stay displayed after you have stopped pressing the button. The MiniMed Veo is shipped from the factory with the default setting of 2 minutes. The options available in the settings menu are 2 minutes, 4 minutes, 6 minutes, or “NONE”.
This option is a convenience for people who do not want the Sensor Graph screen to stay displayed. Because it can affect the function of the Low Glucose Suspend feature, we do not recommend it.
There is not an alarm that occurs at the end of the 2 hour period. However, whenever your pump is suspended, it will beep 3 times every 15 minutes to remind you that no insulin is being delivered. All the pump and sensor alarms and alerts will work while the pump is displaying the Sensor Graph screen.
This behaviour will not occur unless your Sensor Graph Timeout setting is set to “NONE” and you use the Low Glucose Suspend feature (on the MiniMed Veo pump).
If you are not sure of your Sensor Graph Timeout setting:
The pump is designed to withstand occasional drops or bumps, however when this happens it is recommended to check the pump for cracks or damage. We have learned about some users having experienced issues with the drive support cap of the pump (see picture below) and we want to proactively inform our customers how to avoid experiencing similar challenges. The pump’s drive support cap holds the pump motor in place and allows the motor’s piston to press against the reservoir to deliver insulin.
In rare cases, the cap may stick out from the bottom of the reservoir compartment. This condition can occur when the pump is damaged due to impact with a hard surface (for example if it is dropped). If the loose drive support cap is pressed, it could result in the unintended delivery of additional insulin.
Some customers have experienced a loose drive support cap, and in rare cases the cap may stick out from the side of the insulin pump as a result of impact with a hard surface. In most cases, the loose drive support cap will result in an A33 or Motor Error Alarm during the manual prime/fill tubing process. While the risk to you is low, we’re asking you to examine the drive support cap on your insulin pump. To locate the drive support cap:
The insulin pump’s drive support cap holds the insulin pump motor in place and allows the motor’s piston to press against the reservoir to deliver insulin.
Copy Pushing on the drive support cap can result in unintended insulin delivery if the cap is loose. The drive support cap should appear slightly indented at all times (as shown in the image). However, in rare cases, the cap may stick out from the side of the insulin pump as a result of impact with a hard surface.
If you notice that the cap is loose, or sticking out, discontinue use of the insulin pump and contact your HelpLine. DO NOT PRESS ON THE DRIVE SUPPORT CAP IF IT IS STICKING OUT.
All MiniMed Veo insulin pump models may be affected. You can find the insulin pump model in the status screen or on the back label of the insulin pump.
Because your child’s safety and product quality are so important to us, your Medtronic insulin pump is manufactured to meet an international standard and requires durability against shock and drop.
If your child drops the insulin pump a lot, then periodically follow this standard insulin pump drop procedure:
To check for damage associated with a loose drive support cap follow this process:
Standard insulin pump drop procedure
Take care to protect your pump from being dropped.
As explained in the pump user guide of all MiniMed Veo pumps, exposure to water may result in pump alarm, damage of the pump’s internal electronics or cause the buttons to stop working. Below is a copy of the relevant part of the user guide that we ask you to take good note of.
Our MiniMed Veo insulin pumps have an IPX7 rating, which means they can usually withstand an accidental dunk or splash but should not be immersed in water. This means the insulin pump meets the water standard of 1 metre (approximately 3 feet) for 30 minutes.
The MiniMed® 640G insulin pump, when properly assembled with the reservoir and tubing inserted, is waterproof (watertight rating IPX8) at depth of up to 3.6 metres (12 feet) for up to 24 hours.
Your insulin pump is designed to resist accidental contact with liquids which includes insulin as well as water. If your insulin pump has been exposed to insulin, follow the same steps you would if it was accidentally exposed to water:
While you should not submerge your insulin pump in water during swimming, bathing or other water activities, your insulin pump is designed to resist accidental contact with water, such as a storm. If you get caught in a storm, follow the instructions below:
Constant exposure to moisture can damage your insulin pump. Here are some tips that are helpful in dealing with moisture:
Our MiniMed Veo insulin pumps have an IPX7 rating, which means they can typically withstand an accidental dunk or splash but you should avoid immersing your pump in water.
While insulin pumps are designed and manufactured to be quite sturdy cracking is possible. Because we cannot prevent cracking with absolute certainty, we recommend that insulin pump users do not intentionally submerge their insulin pump in water. Medtronic continuously works to improve product quality and features for both new and existing products. Feedback from customers like you plays a big part in that process. We will be sure to keep you informed on any improvements as they become available.
