What are Insulin Pumps?
People who are living with diabetes and require insulin therapy have to inject insulin numerous times a day, as per their condition and body requirements, obviously.
This has not only been difficult in terms of multiple pins throughout the day, but it has also been limiting people with diabetes. Insulin pumps are designed to save people from these multiple pricks, instead one cannula, with or without a tube, is attached to manage your insulin therapy with ease – supporting your active lifestyle, obviously.
Tubed Insulin Pumps and Their Features
These pumps use tubing (usually available in various lengths) to deliver insulin from a reservoir to a small cannula inserted under your skin. The pump device can be clipped onto your belt or carried in a pocket. Tubed pumps offer precise insulin delivery and advanced features but require careful management of the tubing (catheter). Here are the top examples of closed insulin pumps with its features.
Important Models of Tubed Insulin Pumps
Medtronic Minimed 780 G
Medtronic MiniMed 780G is an advanced hybrid closed-loop insulin pump system designed to help people manage diabetes automatically. It continuously monitors glucose levels and automatically adjusts insulin delivery using built-in SmartGuard™ technology. The 780G system can work with several CGM sensors, including Guardian 4 Sensor and Simplera Sync Sensor, and both are available on CGM Monitors with insurance claim benefits.
Important Note: The 780G does NOT work with Dexcom (G6, Standard G7 and New 15 Days G7 Sensor ) or FreeStyle Libre (Libre 2 Plus and 3 Plus) sensors, because the pump only communicates with Medtronic-compatible CGM sensors.
Medtronic Minimed 770G Insulin Pumps
Medtronic 770G, a semi-automated insulin delivery system that can help streamline your diabetes management. The system can function as a standalone insulin pump without the need for a Continuous Glucose Monitoring (CGM) sensor. However, to fully access advanced features like automated insulin delivery (including automatic basal insulin adjustments and predictive high/low glucose alerts), integration with a compatible CGM sensor is required.
Medtronic Minimed 750G: Phase Out Insulin Pump
The Medtronic 750G is compatible with the Guardian Sensor 3. This insulin delivery system is controlled via the CareLink mobile app Android, the CareLink mobile app Apple, or a separate transmitter, offering enhanced connectivity and remote monitoring. This AID system is indicated for people with type 1 diabetes, 7 years of age and older.
Advantages of Tubed Insulin Pumps
- Precise Customization: Tubed pumps provide extensive programming options for insulin delivery, including basal rates and doses. They are suitable for users requiring highly individualized control over their diabetes management.
- Larger Insulin Reservoirs: Most tubed pumps can hold more insulin, thus reducing the need for frequent refills. This makes them ideal for individuals with higher insulin needs.
- Integration with CGMs: Tubed pumps often integrate seamlessly with Continuous Glucose Monitors (CGMs), creating a closed-loop system that mimics the pancreas.
- Longer Wear Time: Tubed pumps may not need to be changed as frequently as tubeless systems, offering greater convenience for some users.
Drawbacks of Tubed Insulin Pumps
- Visible Tubing: The tubing can be awkward, potentially getting caught on objects or making users feel self-conscious.
- Restricted Movement: Activities like swimming or exercising may require adjustments to prevent tubing issues.
- Portability Challenges: The need to carry the pump on your body at all times may feel restrictive to some users.
- Tubeless Insulin Pumps: Tubeless pumps, often called patch pumps, deliver insulin directly from a wearable pod adhered to the skin. These pumps are controlled remotely, usually via a separate device or smartphone app. They eliminate the need for tubing, offering greater freedom of movement.
Tubeless Insulin Pumps and Their Features
Tubeless insulin pumps or patch pumps are wearable diabetes devices that deliver insulin continuously without external tubing. The pump, insulin reservoir, and cannula are all built into a small patch-like device that attaches directly to the skin. It delivers insulin through a tiny cannula inserted under the skin and is usually controlled wirelessly by a handheld controller or smartphone.
How Tubeless Insulin Pumps Work
- A small patch pump (pod) is filled with insulin.
- It is placed on the body (arm, abdomen, thigh, or back).
- A tiny cannula automatically inserts under the skin.
- The device delivers basal insulin continuously and bolus doses for meals or corrections.
- The pump is controlled via a remote controller or mobile app.
Pods usually last 2–3 days before replacement.
