The Medtronic Mini Med Insulin Pump 780G is a hybrid closed-loop system designed to assist individuals with type 1 diabetes between 7 – 80 years of age. This automatic insulin delivery (AID) system is compatible with Guardian 4 Sensor and Guardian 3 Sensors. Equipped with SmartGuard technology, the system delivers correction boluses, and with meal detection technology, it reduces the hassle of manual carb counting. Thus, minimising adverse events, improving glycemic control and enhancing the quality of life for users. Let’s have a closer look at the features and how they may help people with type 1 diabetes, but before we dive, just have a glance at what insulin pumps are and how they work.
What Is an Insulin Pump?
An insulin pump is a medical device used to administer insulin continuously throughout the day and night. Unlike multiple daily injections, a pump delivers rapid-acting insulin via a small catheter placed under the skin. This method provides more precise and flexible insulin delivery, closely mimicking the body’s natural insulin release. Some insulin pumps only give you your bolus when you instruct from your phone or the AID system controller, while some offer the smart technology that automatically detects your blood sugar levels, based on which they will give you the required bolus doses or correction dose.
The 780g insulin pump belongs to the second type. However, as it is a hybrid closed-loop system, you are still required to input meal boluses.
Who Is It Suitable For?
As highlighted by the medtronicdiabetes, the MiniMed 780G system is primarily intended for individuals with type 1 diabetes aged 7 and above. It is particularly beneficial for those who:
- Experience frequent fluctuations in blood glucose levels.
- Have difficulty achieving target glucose levels with multiple daily injections.
- Desire to minimise the bolus counting and enjoy an automated approach to insulin delivery.
In short, any type 1 diabetic aged 7 plus and fed up of manually calculating carbs or who tends to forget taking insulin boluses may find it useful to opt for a waterproof insulin pump like the Insulin pump Medtronic Mini Med.
Key Features and Sensor Compatibility
The MiniMed 780G system boasts several advanced features:
- Hybrid Closed-Loop System: Based on continuous glucose monitoring (CGM) data, it automatically provides correction boluses every 5 minutes. The best part, new systems allow you to set target blood sugar levels as low as 100 mg/dL.
- Meal Detection Technology: Identifies meals and provides automatic corrections for missed or underestimated carbohydrate intake.
- Water Resistance: The pump is waterproof up to 12 feet for 24 hours, making it suitable for swimming and other water activities.
