Usually worn on the abdomen or upper arm, connected to the cannula inserted beneath the skin.
About the size of a pager or smartphone.
Has a reservoir for holding insulin, a pump to deliver it, and a controller for programming doses.
Some pumps connect to continuous glucose monitoring (CGM) systems for real-time blood sugar readings.
An insulin pump is a small, computerized device worn externally on the body that delivers insulin through a tiny tube (cannula) inserted under the skin.
It mimics the pancreas's function of delivering a continuous flow of insulin, providing more precise control over blood sugar levels than injections.
Improved blood sugar control: Pumps deliver insulin more precisely than injections, leading to tighter blood sugar ranges and reducing the risk of hyperglycemia and hypoglycemia.
Greater flexibility: Doses can be adjusted for meals, exercise, and other activities. Bolus doses for meals can be programmed, and basal rates can be adjusted throughout the day or night.
Reduced finger pricking: CGM systems eliminate the need for frequent finger pricks to check blood sugar.
Improved quality of life: Pumps can provide greater freedom and less anxiety about managing diabetes.
Talk to your doctor: Discuss if an insulin pump is right for you and get trained on its use.
Set up the pump: Fill the reservoir with insulin, insert the cannula, and program the basal rates and bolus doses.
Calibrate the pump: Regularly check the pump's accuracy against finger prick blood sugar readings.
Monitor blood sugar: Use a CGM system or regularly check blood sugar with a meter.
Change the cannula: Replace the cannula every 2-3 days to prevent infection and ensure proper insulin delivery.
Maintain the pump: Clean the pump and reservoir regularly as per the manufacturer's instructions.
Pump malfunctions: Pumps are mechanical devices and can malfunction. Always have backup syringes and vials of insulin on hand.
Skin irritation: The cannula insertion site can become irritated. Monitor the site for redness, swelling, or pain.
Diabetic ketoacidosis (DKA): Although rare, DKA can occur if the pump malfunctions or the cannula becomes dislodged. Be aware of the signs and symptoms of DKA and seek immediate medical attention if needed
