Insulin Easier

The Pentander insulin pump aims to revolutionize the insulin pump industry by being the first patch pump to utilize U500, a more concentrated form of insulin than the commonly used U100. Existing patch pumps only last up to 3 days, making maintenance difficult and expensive. Using U500 allows the Pentander pump to be smaller, lighter, and last longer. The delivery volumes for the Pentander pump need to be 5 times smaller than pumps on the market, so the Pentander team has come up with a two part design that involves both a passive pump and a regulator. In the passive pump portion, pressure is supplied using a spring. The regulator then dispenses a discrete amount of insulin at a time, allowing patients to monitor their dosages. The goal of the Pentander pump is to make management easier and more affordable for the millions of people affected by type one diabetes
