2. Patch pumps

We worn Patch pumps on the skin like a patch and connect it to a catheter under the skin. They are smaller and less visible than traditional pumps and deliver insulin continuously.

How Insulin Pump Works

Insulin pumps are small, computerized devices that deliver insulin continuously throughout the day through a small tube placed under the skin. The insulin pump is programmed to deliver continuous insulin the whole day and additional doses at mealtimes.

A tubing connects the pump to the catheter and the pump is worn on a belt or waistband. The patient can adjust the insulin delivery rate as needed, such as increasing the basal rate during increased activity or decreasing it during rest.

The pump also has a feature called a bolus calculator, which helps the patient calculate the amount of insulin needed at meal times based on the carbohydrate content of the meal and the patient’s blood sugar level.

Insulin pumps are a popular treatment option for people with Type 1 diabetes, as they can help to improve blood sugar control and reduce the risk of complications from the disease.
