As with the finished device, it is equally important to fully vet a proposed seal design through prototyping to ensure that it will pass regulatory scrutiny and withstand the manufacturing process. It is essential to choose a supplier with expertise in seals designed specifically for insulin pumps and with an understanding of the regulatory requirements with regard to engineering, quality control, and materials. The supplier must have adequate resources to help determine the optimal sealing solution for the pump design, including but not limited to material compatibility testing, prototyping options, non-linear finite element analysis (FEA), and lifecycle testing capabilities.


For people struggling with the complexities of insulin-dependent diabetes, the idea of more automated, less-intrusive ways to manage their disease is a welcome change. Technology partnerships hold particular promise, such as Medtronic’s announcement that it is working with IBM Watson to develop an app called Sugar.IQ, which acts as a personal assistant for people with diabetes.

Selecting the proper seal for an insulin pump application ensures the adequate design, functionality, and compliance to deliver safer and more precise dosages of insulin. Device manufacturers that take advantage of new seal technologies will drive the growth of the insulin delivery device market. Lighter, smarter devices paired with sophisticated drug-delivery systems will accelerate the pace of innovation. The increasing number of people affected with diabetes is bringing focus to the market and the resulting need to manufacture safe insulin devices with defect-free sealing technology. The goal is to ensure that patients with this chronic disease can be as active, healthy, and comfortable as possible.
