What is insulin pump and how does it work?

A small electronic device, like a free (same size of a mobile phone) that check your metabolic insulin and prevent you from hypoglycemia and hyperglycemia, called as the insulin pump.

 It can be easily carried on a belt, inside a pocket, or even attached to a bra thus becoming virtually invisible to others and allowing a very discreet therapy.


How insulin pumps work in the body?

  • The pump, through a Continuous Subcutaneous Insulin Infusion (CSII), replaces the need for frequent injections by delivering precise doses of rapid-acting insulin 24 hours a day to carefully match your body’s needs.

Basal Rate:       

  • A programmed insulin rate made of small amounts of insulin delivered continuously mimics the basal insulin production by the pancreas for normal functions of the body (not including food).
  • The program rate is determined by your healthcare professional based on your personal needs. This basal rate delivery can also be customized according to your specific daily needs.
  • For example, it can be suspended or increased/decreased for a definite time frame; this is not possible with basal insulin injections.

Bolus dose:

  • Additional insulin can be delivered “on demand” to match the food you are going to eat or to correct high blood sugar, also known as the bolus dose.
  • Insulin pumps have bolus calculators that help you calculate your bolus amount based on settings that are pre-determined by your healthcare professional and again based on your particular needs.

Benefits of the insulin pump:

  • Insulin pump therapy has multiple benefits as the comparison to insulin injections. It is more beneficial for type 1 diabetic people, But also useful for type 2 diabetes. It has following advantages:
  • It can control HbA1c much better.
  • Usually, people less expose to hypoglycemic events.
  • Fewer variations in glycemic variability and more control.
  • It can help to manage the need for insulin dose adjustment better, particularly for meals and overnight and can thus contribute to achieving better glucose control.
  • The ability of adjustment insulin dose and more prevention from complication as compared to other diabetic control medicine.
  • Insulin calculation is the most challenging task for people in routine. It can help to accurate dosing with a calculation of body insulin, current glucose level, and intake amount of carbohydrates.
  • The amount can also personally control.
  • It has greater flexibility because it instantly adjusted to allow for exercise or illness or heavy meal. It delivers insulin according to body’s metabolic condition.
  • There is even a temporary basal rate option to proportionally reduce or increase the basal insulin rate, during exercise or illness.

It has regulatory monitor:

  • This meter automatically sends blood glucose values to the pump, allows for more accurate Bolus calculations and to deliver insulin boluses discreetly.

Parts of the insulin pump:

The insulin pump consists of:

  • A compartment that holds a reservoir.
  • The reservoir which is filled with insulin.
  • From the pump’s reservoir, insulin is infused into your body through an infusion set.
  • The infusion set is inserted into your body and is introduced through a tiny flexible tube called a cannula that sits just underneath your skin.
  • The infusion set is then connected to the reservoirs through a small tube which can be easily disconnected and reconnected from your body whenever you want to. This is helpful when people want to swim, shower or play a sport.
