MEDTRONIC MINIMED 640G (01) PDF Document

Your emergency kit for the MEDTRONIC MINIMED 640G system should always be with you and include the following items:

• Fast-acting glucose tablets.

• Blood glucose monitoring supplies.

• Urine or blood ketone monitoring supplies.

• Extra MiniMed-compatible infusion set and MiniMed reservoir.

• Extra new AA lithium or alkaline batteries, or fully charged NiMH batteries.

• Insulin syringe and fast-acting insulin (with dosage instructions from your healthcare professional).

• Wallet card (packaged with your pump accessories).

• Adhesive dressing.

• Glucagon emergency kit.

At the time of manufacture and when the reservoir and tubing are properly inserted, your MEDTRONIC MINIMED 640G pump is waterproof. It is protected against the effects of being underwater to a depth of up to 3.6 meters (12 feet) for up to 24 hours.

If the pump is dropped, hit against a hard object, or otherwise damaged, the waterproof characteristics of the outer casing may be compromised. If your pump has been dropped or you suspect damage, carefully inspect it for any cracks before exposing it to water.

The following table describes how to use the buttons on your MEDTRONIC MINIMED 640G pump:

To insert the battery into your MEDTRONIC MINIMED 640G pump:

1. Insert the new or fully charged AA battery, making sure to insert the negative end (–) first. After you insert the battery, the positive end (+) is visible.

2. Use the belt clip to tighten the battery cap. Turn the battery cap clockwise until the cap is aligned horizontally with the pump case. Do not overtighten or undertighten the battery cap, as overtightening can damage the pump case, and undertightening can prevent the pump from recognizing the new battery.

To remove the battery from your MEDTRONIC MINIMED 640G pump:

1. Before removing a battery, clear any active alarms or alerts.

2. Use the belt clip to loosen and remove the battery cap. If the belt clip is unavailable, you may use a coin.

3. Remove the battery.

4. Dispose of old batteries according to local disposal requirements.

5. After removing your battery, wait until the Insert Battery screen appears before inserting a new battery. Be sure to replace the battery within 10 minutes to avoid a Power loss alarm.

When you insert the battery for the first time, the Startup Wizard will guide you through the initial settings. Follow these steps:

1. The Startup Wizard begins after the Welcome screen appears. When the Language screen appears, select your language.

2. When the Select Time Format screen appears, select a 12 hour or a 24 hour time format.

3. When the Enter Time screen appears, adjust the setting to the current time. If you are using a 12-hour clock, specify AM or PM. Select Next.

4. When the Enter Date screen appears, adjust the Year, Month and Day to the current date. Select Next.

A message confirms that your initial setup is complete, and then the Home screen appears.

6. Repeat for other time segments if needed, then select Done and Save.

When your MEDTRONIC MINIMED 640G pump suspends insulin due to a Suspend before low or Suspend on low event, you can manually resume delivery instead of waiting for it to resume automatically.

1. From the Home screen, select the status message at the bottom (e.g., Suspended before low or Suspended on low).

2. The SmartGuard screen appears.

3. Select Resume Basal.

4. Select Yes to confirm and resume basal delivery.

You can connect your transmitter using either Auto Connect or Manual Connect.

Using Auto Connect:

1. Attach your transmitter to the charger and ensure it is fully charged.

2. On your pump, go to Menu > Utilities > Device Options > Connect Device > Auto Connect.

3. Read the on-screen information and select Continue.

4. Place the transmitter (still on the charger) next to the pump.

5. Select Search on your pump and immediately remove the transmitter from the charger.

6. When the pump finds the transmitter, ensure the serial number on the pump screen matches the one on your transmitter, then select Confirm.

Using Manual Connect:

1. Write down the serial number (SN) from the back of your transmitter.

2. Attach your transmitter to the charger and ensure it is fully charged.

3. On your pump, go to Menu > Utilities > Device Options > Connect Device > Manual Connect.

4. Use the pump navigation buttons to enter the serial number of the transmitter and select OK.

5. Select Search on your pump and immediately remove the transmitter from the charger.

6. A success message will appear when the connection is complete.

If your pump cannot find the sensor signal, follow the troubleshooting steps on the pump screen, which include:

1. Ensure your setup meets requirements: transmitter is fully charged, it is the only one connected to the pump, it’s placed next to the pump, and Airplane Mode is off.

2. Disconnect the transmitter from the sensor for at least 10 seconds.

3. Reconnect the transmitter to the sensor. While the transmitter light is blinking, select OK on the pump.

4. The pump will ask if the transmitter light blinked. Select Yes or No.

• If you select No, the pump will advise you to charge the transmitter.

• If you select Yes, proceed to the next step.

5. Move your pump closer to the transmitter and select OK. It may take up to 15 minutes to find the signal.

6. If it still cannot find the signal, ensure you are away from other electronic devices that might cause interference (like cellular phones) and select OK again.

7. If you still cannot find the sensor signal after these steps, contact your local representative for assistance.

Calibration requires you to enter a BG meter reading into the pump. You must calibrate at a minimum of every 12 hours.

To calibrate your sensor:

1. Take a BG meter reading.

2. Go to the Calibrate Sensor screen: Menu > Sensor Settings > Calibrate Sensor.

3. Select BG and enter the value from your BG meter reading.

The “Insulin flow blocked” alarm means your MEDTRONIC MINIMED 640G pump has detected that the basal or bolus insulin flow was blocked. Because insulin delivery is stopped, you must take immediate action.

Follow these steps:

• Check your blood glucose. Consider checking ketones and take an injection if needed.

• Remove your infusion set and reservoir.

• Select Rewind to start the new reservoir process using a new infusion set and reservoir.

If a bolus delivery was in progress when the alarm occurred:

• Check the Daily History screen for the amount of bolus already delivered before the pump alarmed.

• Consider delivering the remaining bolus, if the bolus insulin was not included in an insulin injection.

A “Critical pump error” alarm indicates that your MEDTRONIC MINIMED 640G pump has encountered a critical error and is not able to deliver insulin. The screen will display an error icon and the pump will siren.

You must take the following steps immediately:

• Immediately disconnect from your insulin pump and discontinue use.

• Consider another form of insulin delivery. Remember, your body still needs insulin while your pump is removed.

• Check your BG and treat as necessary.

• Write down the error code that appears on the alarm screen.

• Contact your local representative for assistance.
