FDA-approved insulin pumps used for insulin pump therapy

Insulin Pump Devices 

An insulin pump is a compact, wearable device that administers short-acting insulin in small increments every few minutes throughout the day and night. It can also provide additional doses of short-acting insulin with the press of a button, either during meals or to lower high blood glucose levels. Insulin pumps generally come in two types: traditional tubed and tubeless (Figure 1). 

The adoption of insulin pumps has grown significantly, with over 350,000 users in the US today, primarily those with type 1 diabetes (T1D). The insulin pump market is projected to reach 10.3 billion USD by 2032, driven by a compound annual growth rate of 8.1% from 2023 to 2032, according to DataHorizzon Research.
