Insulin Pumps
Insulin Pumps in Pediatric Diabetes Management
Overview
An insulin pump is a sophisticated medical device that delivers precise amounts of rapid-acting insulin continuously throughout the day through subcutaneous tissue. It serves as an alternative to multiple daily injections in managing type 1 diabetes in pediatric patients.
