An insulin pump is a small, computerized medical device that delivers insulin to people with diabetes. It is worn outside the body, usually clipped to a belt or waistband, and produces insulin through a small tube (catheter) inserted under the skin. The pump delivers a daily continuous and adjustable insulin dose based on programmed settings and the user’s needs. It can also deliver a larger amount of insulin at mealtimes with the push of a button. Insulin pumps are often used by people with type 1 diabetes, but they may also be used by some people with type 2 diabetes who require insulin therapy.
Where can we wear insulin pump?
Insulin pumps can be worn on various parts of the body that have subcutaneous tissue, which is the layer of tissue just below the skin. Common locations for wearing an insulin pump include:
Abdomen: The abdomen is a popular location for insulin pump users due to the abundance of subcutaneous tissue and the ease of access for inserting the infusion set.
Thighs: The thighs are another common location for insulin pump wearers, as they provide a discreet location and are convenient for active individuals.
Hips: The hip area, including the upper buttocks, can be a good location for wearing an insulin pump, as it is relatively comfortable and out of the way during daily activities.
Arms: Some people choose to wear their insulin pumps on their upper arms, which can be a good option for those who prefer a more discreet location.
Overall, the location for wearing an insulin pump can vary depending on individual preference and comfort. It is important to choose a location that is comfortable, secure, and allows for easy access to the pump controls and infusion site.
How an Insulin Pump Works?
An insulin pump works by delivering insulin to the body through a small tube (catheter) that is inserted under the skin. Here are the basic steps of how an insulin pump works:
- Basal insulin delivery: The insulin pump delivers a continuous and adjustable dose of insulin throughout the day, known as basal insulin. The amount of insulin delivered can be programmed based on the user’s individual needs, such as their age, weight, activity level, and insulin sensitivity. The basal insulin helps to maintain stable blood sugar levels between meals and overnight.
- Bolus insulin delivery: When the user needs additional insulin, such as before a meal, they can deliver a bolus dose of insulin with the push of a button on the insulin pump. The user inputs the amount of insulin they need based on their meal size and carbohydrate content, and the insulin pump delivers the dose over a specified period of time.
- Monitoring and adjustment: The insulin pump continuously monitors the user’s blood sugar levels using a sensor and adjusts the insulin delivery accordingly. If the user’s blood sugar levels are too high or too low, the insulin pump can adjust the basal insulin delivery or recommend a bolus dose to bring the blood sugar back into range.
- Maintenance: Insulin pumps require regular maintenance, such as changing the infusion site and reservoir of insulin, replacing the battery, and checking for proper insulin delivery.
- Overall, an insulin pump provides a more precise and flexible method of insulin delivery compared to traditional insulin injections. It can help people with diabetes maintain better control over their blood sugar levels, reduce the risk of complications, and improve their quality of life.
How to Use an Insulin Pump?
Consult with a healthcare professional: Before using an insulin pump, it is important to consult with a healthcare professional, such as an endocrinologist or certified diabetes educator. They can help you choose the right pump, set up the device, and teach you how to use it.
Program the pump: The insulin pump needs to be programmed with your settings, such as basal rates, insulin-to-carbohydrate ratios, and correction factors. Your healthcare professional can help you determine these settings based on your insulin needs and blood sugar goals.
Insert the infusion set: The infusion set is part of the insulin pump that delivers insulin to your body. It includes a small, flexible tube (catheter) inserted under the skin and a small adhesive patch that holds the tubing in place. You will need to change the infusion set every 2-3 days. Here’s how to insert the infusion set:
Clean the skin where you plan to insert the infusion set.
Fill the insulin reservoir and connect it to the infusion set tubing.
Remove the adhesive backing from the infusion set patch and place it on your skin.
Insert the catheter into your skin using the insertion device provided with the infusion set.
Remove the insertion device and connect the tubing to the pump.
Program a bolus dose: When you need additional insulin, such as before a meal, you can program a bolus dose into the insulin pump. Your healthcare professional can help you determine the appropriate bolus dose based on your meal size and carbohydrate content. Here’s how to program a bolus dose:
Navigate to the bolus dose menu on the insulin pump.
Enter the amount of insulin you need based on your meal size and carbohydrate content.
Confirm the bolus dose and deliver the insulin.
Monitor your blood sugar levels: When using an insulin pump, it is important to monitor your blood sugar levels regularly. You can use a blood glucose meter or a continuous glucose monitor (CGM) to check your blood sugar levels. The insulin pump can also be set up to alert you if your blood sugar levels are too high or too low.
Maintain the insulin pump: Insulin pumps require regular maintenance, such as changing the infusion set and reservoir, checking for proper insulin delivery, and replacing the battery. Follow the manufacturer’s instructions for maintenance and troubleshooting.
