how to choose the best insulin pump
what are insulin pumps
Insulin pumps are primarily used by individuals with type 1 diabetes (because body stops producing insulin) , although some people with type 2 diabetes who require intensive insulin therapy may also benefit from using insulin pumps. Insulin pumps are small electronic devices designed to deliver insulin continuously throughout the day. They are about the size of a pager or small cell phone and are worn externally, typically attached to a belt, pocket, or clothing. These devices are primarily used by individuals with diabetes who require insulin therapy to manage their blood sugar levels.
Insulin pumps consist of several key components:
- Reservoir: A cartridge or reservoir holds the insulin and is connected to the pump.
- Pump: The pump is the main unit that houses the electronics and mechanics responsible for delivering insulin.
- Infusion Set: A thin, flexible tube called an infusion set is connected to the pump and inserted under the skin to deliver insulin into the fatty tissue (subcutaneous tissue).
- Controls: The pump is equipped with controls and a screen to allow the user to program insulin delivery settings, monitor insulin doses, and interact with the device.
Unlike traditional insulin injections, which require multiple daily shots, insulin pumps deliver insulin continuously in small doses, mimicking the natural release of insulin by the pancreas. This continuous delivery provides a more steady and precise control of blood sugar levels throughout the day.
How insulin pumps work in managing diabetes
Insulin pumps are small, pager-sized devices that deliver insulin continuously throughout the day. Insulin pumps work by delivering insulin continuously at a programmed basal rate and providing additional insulin doses (boluses) to cover meals or correct high blood sugar levels. Here’s how insulin pumps function in managing diabetes:
Continuous Insulin Delivery: Unlike traditional insulin injections, which require multiple daily shots, insulin pumps deliver insulin continuously through a tiny catheter inserted under the skin. This continuous delivery mimics the natural release of insulin by the pancreas, providing a more stable blood sugar level throughout the day.
Basal and Bolus Insulin: Insulin pumps deliver two types of insulin: basal and bolus. Basal insulin is delivered continuously at a low rate to meet the body’s basic insulin needs between meals and overnight. Bolus insulin is delivered in larger doses to cover meals and correct high blood sugar levels. With an insulin pump, you have the flexibility to adjust both basal and bolus insulin doses according to your individual needs.
Programming and Adjustments: Insulin pumps are programmed with personalized insulin delivery settings based on factors such as your weight, insulin sensitivity, and lifestyle. These settings can be adjusted by you or your healthcare provider to optimize blood sugar control. For example, you can program different basal rates for different times of the day or adjust bolus doses to account for changes in meal size or physical activity.
Carbohydrate Counting and Bolus Wizard: Many insulin pumps are equipped with features like carbohydrate counting and bolus calculators to simplify mealtime insulin dosing. With these features, you can enter the amount of carbohydrates in your meal, and the pump calculates the appropriate bolus insulin dose based on your insulin-to-carbohydrate ratio and blood sugar level.
Integration with Continuous Glucose Monitoring (CGM): Some insulin pumps can be integrated with CGM systems, allowing for real-time monitoring of blood sugar levels and automatic adjustments to insulin delivery. This integration provides greater insight into blood sugar trends and helps prevent highs and lows by adjusting insulin doses accordingly.
Site Rotation and Maintenance: To ensure optimal insulin absorption and minimize the risk of complications, it’s important to rotate infusion sites regularly and follow proper site care procedures. Insulin pump manufacturers provide guidance on site rotation and maintenance to help prevent issues such as infection or insulin absorption problems.
Now that you have understood how insulin pumps work for diabetes management, you should know what various types of Insulin Pumps are available in the market before making a decision.
Types Of Insulin Pumps Available In The Market
There are several types of insulin pumps available in the market, each with its features, advantages, and limitations. The main types of insulin pumps include:
- Traditional Insulin Pumps: These pumps are worn externally and deliver insulin through a thin tube (infusion set) inserted under the skin. They typically use rapid-acting insulin and allow for continuous basal insulin delivery and bolus doses.
- Patch Pumps: Patch pumps are compact, tubeless insulin pumps that adhere directly to the skin. They are discreet and offer more freedom of movement compared to traditional pumps. Patch pumps use a pre-filled insulin reservoir and are discarded after a certain period (e.g., 2-3 days) when the insulin runs out.
- Hybrid Closed-Loop Systems: Some insulin pumps are integrated with continuous glucose monitoring (CGM) systems to create hybrid closed-loop systems, also known as artificial pancreas systems. These systems automatically adjust insulin delivery based on real-time CGM data, helping to maintain stable blood sugar levels without the need for constant manual intervention.
