OnePress is an integrated long-term injection system designed for people with multiple sclerosis. Multiple sclerosis often requires lifelong, frequent injections, yet patients face problems mainly including declining hand function, injection-site rotation errors, and growing medical waste over time. It addresses fine motor decline and fragmented therapy experiences by combining storage, prewarming, injection, and tracking into a single, seamless experience, enabling safer, more confident, and consistent self-injection at home.
