What is an insulin pump?

.

Insulin pumps are computerized electromechanical devices that house an insulin reservoir or cartridge.

The insulin in the cartridge is dispensed through an infusion system, of which there are several types, which is inserted into the subcutaneous tissue, usually in the abdomen. Insulin, to cover basal needs, is infused almost continuously, so that insulin deposits do not form in the subcutaneous tissue, appreciably increasing its effectiveness.

The basal insulin infusion can be varied throughout the day and some pump models allow programs to be recorded for different times in different situations: weekdays, shift changes, holidays, etc.

Insulin boluses is the infusion used to cover food intake; are supplied on demand and can be performed immediately (normal bolus), or spread over a certain period of time (extended bolus), or combining both types. There is also the advanced bolus function, which calculates the amount of Insulin needed depending on the type of food to be eaten and / or the user's conditions, glycemic target, insulin sensitivity factor, carbohydrate index.

Current insulin pumps are very safe devices, small in size and weight (similar to a small mobile phone) and very simple to handle and easy to program. Currently there are models capable of infusing basal amounts as small as 0.1 units per hour and delivering specific boluses of insulin, allowing an optimal degree of control to be achieved. In addition, insulin pumps tend to have a very positive impact on improving the quality of life of people with diabetes. The current size of insulin pumps contributes to this improvement. Small enough to allow their comfortable and discreet portability, extremely user-friendly handling and their extremely high reliability and safety.
