Therapeutic Devices encompass infusion pumps, dialysis machines, ventilators, and implantable drug delivery systems, each requiring seals that ensure fluid containment, pressure regulation, and biocompatibility. The seals must resist prolonged exposure to saline, blood, and pharmaceutical compounds while maintaining flexibility for compact device architectures. This application contributes approximately 20 % to the total market, propelled by rising chronic disease prevalence and increased home‑care therapy adoption. The critical nature of therapeutic equipment elevates the importance of seal reliability, as failures can lead to dosage errors or device malfunction. Manufacturers therefore invest in advanced sealing technologies, such as silicone‑based O‑rings and custom‑molded gaskets, which command premium pricing and reinforce the overall market size.
